SPECIFICATION forming part of Letters Patent No. 681,439, dated August 27, 1901. Application filed September 14, 1898- Serial No. 690,901. (No model.)

To all whmn it nuty concern:

Be it known that I, HOWARD CARR, a citizen of the United States, residing at San Francisco, county of San Francisco, and State of California, have invented certain new and useful Improvements in lVIagazine-Guns,fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates especially to an improved gun of that class known as recoiloperated guns, in which the energy developed by the recoil when the gun is fired is utilized in retracting the breech-block from the barrel to open the breech and performing the other operations of the gun required for a new discharge.

The invention is intended especially for use in machine or field guns; but itis applicable also to other classes of firearms.

The especial object of the presentinvention is to provide an improved machine or field gun employing the breech-movement of my prior Letters Patent No. 584,153, dated June 8, 1897; and the invention includes certain improvements in the construction and arrangement of the parts by which the recoil is utilized in performing the breech operations and certain features of construction and combinations of parts in a gun of this general organization, as well as certain features of construction which are applicable also in other classes of guns employing a different breech movement. I have devised also a novel magazine construction and means for feeding cartridges therefrom to the barrel, which in themselves form parts of the invention and may be used also in other classes of magazineguns,although preferably combined with the other features of the invention.

For a full understanding of the invention a detailed description of a construction embodying all the features of the same as applied in their preferred form to a field-gun and a modified magazine construction will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention will then be specifically pointed out in the claims.

Figs. 23 and 24 are details of the pawl and pawl-lever. Figs. 25 and 26 are detail plan views of the bottom of the magazine casing.

In giving a detailed description of the gun I will first describe the breech mechanism of the gun proper, after which similar detailed descriptions will be given of the novel magazine shown and its operating devices and of the tripod construction.

Referring now to the drawings, and especially to Figs. 1 to 10, A is the barrel, and B the barrel-extension, which may be formed integral with or secured to the barrel, and O the breechblock, sliding in the extension. The barrel A and extension 13 move longitudinally in a frame or casing D, which, as in the form shown, consists of a rectangular casingsurrounding the extension B and having an opening 15 at the bottom for the discharge of the empty shells and an opening 16 at the top for the reception of the live cartridges from the magazine. The frame D has a forwardly-extending cylindrical portion E, which surrounds the breech portion of the barrel A and serves as a guide and support for the barrel during its movement. A still further support for the oarrelis provided by the sleeve E, hereinafter described. The frame D has also a rearwardly-extending arm or tongue F, which forms the stock or handgrip. The barrel extension B consists of two side plates 17, joined by a screw-threaded extension, into which the barrel A is screwed, and of a shape conforming to the inner wall of'the frame D, in which they fit snugly, said barrel extension B forming acasing inclosing the breech-block and its operating parts and being open at the top and bottom for the reception of the cartridges and expulsion of the shell, as in the case of the frame D. t The breech-block C is provided with ribs 19, which run in grooves formed in the upper part of the sides 17 of the casing forming the extension B and by which the breech-block is guided and held in position. The breechblock also carriesk'on either side the springpressed extractors ct, also running in grooves in the sides of the casing forming the extension B. The ejector b is pivoted on pin 21 in the'rear end of the casing B and enters a groove 22 in the under side of the breech-block U, the forward portion of the ejector I) being slightly curved downwardly and the end inclined. The groove at the end of the breechblock 0 is also inclined to conform to the shape of the ejector and pressit down to force the shell out of the extractors a when the breechblock is in retracted position, as shown in pass under the ejector on its return.

a when the breech-block C is drawn rearward the upper portion of the head of the shell will pass under the inclined end of the ejector b, which is stationary with the barrel extension B, and be pressed down by the curved inclined surface at the end of the breech-block, and thus be forced down out of the grasp of the extractors, when it will fall between the sides 17 of the extension B and through the opening 15 in the frame D. The breech-block O is connected to the barrel extension B by a pair of links K L, pivoted together at 23, the forward end of the front link K being pivoted to the breech-block O by the pivot 24 and the rear end of the rear link L to the barrel extension B by a pivot 25. The link L is preferably forked, as shown, consisting of two side plates, which embrace the rear end of the link K and aiford space for a central hammer within the breech-bolt.

Mounted in the forward end of the breechblock G is the firing-pin c, which consists of a disk having a pin on its forward side and a central slot through which passes the pin 24, which limits the movement of the firing-pin c in both directions. The firing-pin c is engaged at its rear end and actuated for firing by a bar d, which is practically a part of the firing-pin, but is separate therefrom to allow the link K to turn on the pivot 24. This bar 01 is supported in the link K by a slot-and-pin connection 26 to allow the bar at to be forced forward to engage the firing-pin c. The bar d extends rearward to the end of the link K, and the link L has a similar short bar d, mounted in the link by a pin-and-slot connection, as shown, so as to have a limited movement in the link. This bar cl is actuated by the hammer e in firing the gun, and

in turn actuates the bar d .to force the firingpin 0 forward to explode the cartridge. The hammer ccarries a cross-pin 27, which moves in horizontal grooves in opposite sides of the barrel extension B, being guided thereby in a straight line, and the pin 27 passes through slots 28 in the side plates of the link L. The slots 28 have a horizontal portion, in which the pin 27 lies in the normal position of the gun, and an upwardly-inclined portion, by movement in which the pin 27 breaks down the links for retracting the breech-block. The hammer carries on its lower side a cross-pin 29, adapted to be engaged by the upward extension on the hand-lever H, so that the breech can be readily opened by hand, as described hereinafter. At its rear end thehammer e is pivoted by pin 30 between two side plates, which form a lever f, which is connected at its lower end to the base of the barrel extension B by links 31, and between the hammerc and links '31 the lever is pivotally connected by a pin 32 to two side plates g g, cut away on their the plates g g are entered by the head 34 of IIO a spring-rod 35, the head 34 having formed on it two lugs 36, which enter openings 37 in the forward ends of the plates g g, as shown in Figs. 3 and 7. The rod 35 has coiled about it a spring 38, one end of which bears against and is held under tension by an adjustable nut 39, screw-threaded on the outer end of the rod 35, the other end of the spring 38 bearing against a head 40, which connects and forms part of the hand-lever bars 41, which extend rearward and are pivoted to the hand-lever H. This spring 38 is the op erating-spring of the breech mechanism put under tension by the recoil and by which all the operations of the breech mechanism are performed and the magazine advanced. The spring 38 and rod 35 are inclosed in a casing G, screw-threaded at its inner end to the frame D and secured at its outer end to the under side of the sleeve E by a screw 42.

The lever f has pivoted at 43 between its two side plates a catchhook h, forming the sear by which the hammer is held in firing position and which is released by the trigger, this sear being adapted to engage either one of two teeth 10 11, formed in a catchblock 44. This sear h carries a flat curved spring 45 on its upper surface, the free end of which engages the inner curved bearingsurface 46 of the stock F, so that the spring 45 operates to press the sear it down into engagement with either one of the two teeth 1O 11 for the operation of the gun, as hereinafter described. The sear It carries a pin 12, adapted to enter a notch 13 in the catchblock 44 when the breech-block 0 has been retracted, and the sear 77. engages the tooth 10, as shown in Fig. 4, and forms a fulcrum for the rocking of the sear h to release it from the tooth 10 as the breech-block returns to close the breech, and as the sear h leaves the tooth 10 it is forced by the spring 45 into position to engage with the tooth 11 of the catch-block 44. The sear h'is thrown out of engagement with the tooth 11 by means of a tripper 48, pivoted to the stock at 49. This tripper 48 has two arms 5 6, the arm 5 entering an opening in the block 44 near the tooth 11 and the upper end of the arm 5 lying directly beneath the sear 7t when the sear is in engagement with the tooth 11. The other arm 6 extends down and forward, with its end in position to be engaged by a pivoted catch on the trigger Z and by a vertical pin 7, loosely mounted in the trigger-block 50, this pin 7 being the means by which the trigger acts to hold the tripper 48 in position with the sear hraisedforcontinuousfiringofthegun. The tripper 48 is spring-pressed downward by a spring 51. The tripper 48 is actuated for firing the gun by a swinging catch 52, pivoted at 1 in a groove formed in the trigger Z, the end 2 of the swinging catch 52 engaging the end of the arm 6 of the tripper 48 to swing the tripper upward on its pivot 49 and raise the arm 5 to release the sear h from the tooth 11. The swinging catch 52 carries a pin 3, which enters holes 4 in the side plates of the trigger Z, the holes 4 being elongated or somewhat larger than the pin 3, thus allowing the catch 52 to be swung upward and downward slightly on the pivot l. The trigger-spring 8 has a tongue 8, forming a light spring-bearing on the top of the catch 52, so as to return it to position with the pin 3 at the bottom of the holes 4. With this construction the pulling of the trigger lifts the tripper by the engagement of the end 2 of the catch 52 with the lower end of the arm 6, so as to release the sear hfrom the tooth 11, and the catch 52then slips off and passes the arm 6, so as to allow the tripper to be returned to normal position by the spring 51, even though the trigger be held back, thus permitting the sear h to engage the tooth 11 when again brought into proper position therefor by the action of the breech mechanism, so as to assure single firing. In raising the arm 6 the catch 52 is swung upward on its pivot 1 against the tension of spring 8, so that the pin 3 is at the top of the holes 4, and when the catch has passed the arm 6 and is thus released the spring 8 swings the catch 52 downward on the pivot 1 until it is stopped by the pin 3 striking the bottontof the holes 4, this downward swinging of the catch carrying its end 2 forward sufficiently to permit it to pass the end of the arm 6 as the trigger is returned by the trigger-spring 8 when re-' leased by the finger, and the end 2 of the catch 52 being again brought beneath the arm 6 when the trigger is returned to normal position, so as to engage the arm 6 again on the next pull of the trigger. To prevent the trigger from actuating the pin 7 in single firing, the trigger is provided with a notch 9, directly in line with the pin 7, this notch 9 being deep enough to allow the upward firing movement of the triggerl without striking the pin 7. When the gun is used for continuous firing, the notch 9 in the trigger is covered by a plate 53, which is mounted on the trigger and adapted to be moved thereon to cover or uncover the notch 9 by a pin-and-slot connection 14. When the plate 53 is moved to cover the notch 9, the upper end of the plate 53 will engage the lower end of the pin 7 when the trigger is pulled and lift the pin, so as to hold the tripper 48 raised and the sear h out of position to engage the catch ll as long as the trigger is held back. The spring 8, as shown clearly in plan View in Fig. 10, is fast to the trigger-block 50, and besides operating the swinging catch52 by its central tongue 8 bears byits front cross-bar on the upper edge of the trigger Z to return it to position when released by the finger of the operator. In place of the catch construction above described any other suitable device may be used for operating the tripper, such that it will hold and actuate the tripper when the trigger is pulled and permit the trigger-catch to return to position past the tripper for the next firing movement.

Referring now especially to Figs. 1, 2, and

11 to 16, the magazine consists of astationary lug 93 moves, and the parts being" covered outer casing M, circular in form, and an inner rotating cartridge-holder N, in which the cartridges are packed. The casing M consists of an outer cylindrical shell m, bottom m, and a removable cover m The bottom m has a cartridge-opening 99 in line with the feed-opening 16 in the frame D. The bottom mof the casing M also has rigidly attached to it a central vertical sleeve 70, mounted on a vertical support on the gun-barrel by being slipped over it and screw-threaded at the top to receive a screw 87 on the top m This holder 80 is formed by a vertical stud on a ring 81, which is the trunnion-ring of the gun, as hereinafter described, and which is screwed onto the end of the barrel guide or support E and receives the screw-threaded end of the sleeve E. The rear portion of the casing M is supported by the frame D, and its forward portion rests on a block 82, carried by the sleeve E, and is held in proper position and against rotation on the holder 80 by a key or lug 83 on the holder, which enters a notch in the sleeve 70, and by a slotted clip 84 on therear side of the casing, which is entered by a lug 85 on the rear sight 2' when the latter is swung up into vertical position on its pivot 120. The rear sight i also carries an arm 121, which bears upon the top of the casing M, so as to hold it firmly against vertical movement. The rear sight may be held in vertical position by any suitable means, such as are well known in the art. As shown in Fig. 19, a vertically-moving catch-pin 122 is used, engaging a notch in the sight-support. The inner casingor holder N has an outer shell n and an inclined top at, sloping inward to an inner shell n its central portion being horizontal. Depending from the top at is a central sleeve 86, journaled 011 the sleeve 70 of the stationary casing M and supported by shoulders formed on the sleeve 70, so as to be free to rotate thereon. The upper portion of the outer shell n of the holder N is just within the cover M of the casing M, the top 71 of the holder N sloping down and inwardly to the inner shell n at about the inclination of the top row of cartridges. The cartridges are placed in the holder, as shown, in radial vertical rows of five, the rows being separated one from the other by radial partitions 88 89, which form stalls receiving the opposite ends of the cartridges, and the bottom cartridge of each row resting on the bottom m of the casing \4. The cartridges are brought at the proper time to the opening 99 in casing-bottom 7% and opening 16 in the upper part of the gun-frame D and forced through these openings and in front of the retracted breechblock in the following manner:

Pivotally mounted on the outer side of the gun-frame D at 90 is a rocking lever J, the lower portion of which is formed of two fingers 91 92, which are alternately. engaged by a lug 93, carried by the sliding plate g, the frame D having a slot 94, through which the by a casing j on frame D. The upper end 95 of the rocking-lever J is circular and projects through a slot 96 in the bottom m of the casingM and enters an opening in a horizontally-swinging plate I, having a projection forming a pawl 97, which engages teeth formed on the under side of a ratchet-ring 98, fast to theholder N. The plate I is pivoted loosely on a stud 100, rising from the bottom m of the casing M, and coiled about the stud 100 is a spring 101, one end of which is fast to the plate I and the other end is connected by a link 102 to aswinging cartridgeguide 108, which is pivoted at 104 to the under side of a table 105, so as to swing below the latter over'the opening 99. The table 105 extends rearward relatively to the movement of the holderN from a point in advance of the opening 99 and is arranged with its rear edge on the line between the first and second layers of cartridges, so as to allow only the lower layer of cartridges to pass to the opening 99, the second layer passing over the upper surface of the table and gradually falling to the bottom of the casing M over the inclined table-support 124, so that the second layer as the cartridges approach the table is advanced over the top of the table and after passing the table becomes the first or bottom layer from which the gun is fed, and so on for each successive layer.

The spring 101 is normally under tension to hold the pawl 97 against one of the teeth of the ring 98, and when the plate I is swung to the position shown in Fig. 14 to move the holder N forward the tension of spring 101 will be slightly increased by reason of the link 102 and swinging arm 103, which at this time are given a greater movement than the plateI by the forward cartridge of the bottom layer, which is being moved to a position over the Opening 99, pressing against the swinging arm 109 and forcing it forward or away from over the opening 99. The guide 103 is pivoted in such a position that it will normally lie across the opening 99 at an angle, as shown in Fig. 13, and when the holder N is moving and the cartridge next the opening 99 is being moved over the opening it will pressthe swinging guide 103 back to the position shown in Fig. 14' against a block '107, and the under side of the guide 103 is curved or inclined, so that the guide 103 acts to force the cartridge down through the openings 99 1 6 as the spring 101 acts through link 102 to move the guide back to the position shown in Fig. 13. The cartridge passes through the openings 99 16 from the position shown in Fig. 12 and down in front of the breechblock 0, when the latter is retracted and is caught and prevented from falling out of the path of the returning breech-block by two curved supports or holding-plates 8, (shown in Figs. 4 and 12,) which catch the rear por- IIO tion of the cartridge and support it while the forward end is supported bya rest 106 in position to be forced into the barrel, this rest 106 forming part of the barrel extension B Fig. 12 acartridge is shown in full lines in the position it occupies in the openings 99 16 during the withdrawal of the breech-block and in dotted lines after it has been pressed down by guides 103 in front of the retracted breech-block. A follower O, resting on the top of the cartridges, is also provided for the following purpose: When the magazine has been emptied, with the exception of the last layer on top of the table 105, the cartridges in moving over the edge of the table 105 while the. holder is being rotated may rebound, and to prevent this the ring 0, preferably formed of a comparatively wide plate, as shown, is hung on the magazine in such a manner that it will follow the cartridges downward as they move toward the bottom of the holder and press upon them to prevent rebound and secure their proper feed. For this purpose I suspend the ring 0 by links .109 from the top n of the holder N, as shown in Figs.'2 and 11, the links being of the proper length and arranged to allow the ring 0 to lower with the layer of cartridges in the magazine on which it rests, so that the ringholds the cartridges down and thus assures the last layer passing over the edge of the table without rebound.

With the construction above described, when the gunhas been discharged and the barrel and breech-block, with their operating parts, have by the recoil been forced back to the position shown in Fig. 3 the lug 93 will have engaged the finger 91 of the rocking lever J and thrown the lever J to the position shown in dotted lines in Figs. 2 and 3, withdrawing the pawl 97 into the position shown in Fig. 13. Then as the'links K L are broken down and the sliding plate 9 is moved forward by the tension of the operating-spring 38 the lug 93 is'moved from the dotted position shown in Fig. 3 forward to the dotted position shown in Fig. 4 without actuating lever J, but is then in position to engage finger 92 and actuate the lever on further movement of the plate 9, and such further movement occurs during the return of the links and breeck-block to normal position. The moving of the lever J during this return of the breech-block will through the end 95 swing the plate I in the direction of the arrow in Fig. 13 to the position shown in Fig. 14:, and the plate I will through the pawl 97, which engages the toothed ring 98, fast to the holder N, move the holder a space of one tooth-that is, the distance between the center of two cartridges. This movement of the holder will bring a cartridge over the openings 99 16, and the guide 103 willforce the cartridge partially through these openings onto the top of the breech-block, which is then in its normal position, closing the breech. The fingers 91 92 are formed on their lower surface so as to allow the lug 93 to pass under them when the lever J has obtained sufficient movement and act as a lock to prevent swinging of the lever J. I preferably provide a two-leafed spring-plates, fastened to the bottom m of the casing M, one leaf 108 of which engages a tooth of the ring 98 to prevent overthrow and also to press the pawl 97 into engagement with the teeth 98 next to be engaged as it returns to engaging position, and the other leaf 108 engages a teeth 98 to prevent a backward movement of the magazine, as shown in Figs. 15 and 16.

Figs. 17 to 26 show a modified construction of the magazine and means for rotating the holder N. In this case the lever J is dispensed with and the pawl 97 forms a part of a lever 110, having a vertical slot entered by a bar 111, having on its lower surface two studs 112 and 113 and on its upper surface a stud 114. This lever 110 is mounted in an opening 115 in the under side of the sightblock 116 and normally pressed against the upper surface of the opening 115 bya spring 117, carried by the lever and bearing on the 1 gun-frame D. The bar 111 is journaled in the sight-block 116 and the upper face of the frame I) by the studs 112 114,-and the stud 113 runs through a slot 118 in the frame D and enters a cam-groove 119 in the upper face I v of the breech-block C. When the breech is closed, the pin 113 lies in the position shown in dotted lines in Fig. 20, and as the breechblock is retracted the pin 113 will be actuated by the cam-groove 119 to the position shown in full lines in Fig. 20, and thus throw the bar 111, and consequently the pawl 97, which engages the teeth 98, from the position shown in Fig. 21 to the position shown in Fig. 17 and bring a cartridge over the opening 99 under the table 105. In this construction the movable guide 103 is omitted and the table the opposite direction, the spring 117 allow- 1 ing the end of the pawl to lower as it moves along the incline of the tooth 98 until it passes the point of the tooth and then raising the pawl to engage the tooth. It will be seen from this that the lever has a slight rocking movement on the bar 111, and as the lever is held against the upper surface of the sight-block the rear end of the lever 110 is slightly rounded or curved, so as to allow the lever to tilt slightly as the pawl 97 is forced down by the incline of the teeth 98. Aplate or cover w, as shown in Fig. 26, may be used for closing the opening 99 when desired for any purpose, as for re-serving the magazine.

The construction shown in Figs. 17 to 26 isotherwise the same as that shown in the other figures and previously described. To refill I casing M, raised off the support 80.

cover m of the casing M is then removed and holder N drawn off'the sleeve 70 and placed either of the magazines, the rear sight 1' is:

turned down and the magazine, including top down and refilled. The casing M is then placed over the filled holder and the casingv an externally-screw-ihreaded hub 73, the upper part of which is removable to allow the trunnions to be placed in the trunnion-box. A ring 74 is then screwed on over the trunnion-box 73, and a two-part cap-plate 75 is fastened to the end of trunnion 72 by screws stock of the gun for convenient removal.

or otherwise, thus preventing any dust or dirt from entering the trunnion-box. With this construction the parts are such that they can be readily renewed when broken or worn.

A handle and shoulder rest P is shown which is screwed onto a projection on the The rear leg as of the tripod is pivoted at the upper end to the head 71 and consists of a tube which receives the bar 00', adjustable in the tube so as to lengthen or shorten the leg. The lower end of the tube w is shown as split and encircled bya clamp 76, which clamps it tightly to the rod on. An adjusting-clamp 77 on the tube 00 is connected by a chain 78 to the'head 71. The other two tripod-legs y y carry at their upper ends intermeshing geared segments 79, so that they move outward or inward together. The tripod may be adjusted so that the gun is fired from a high position or close to the ground. As shown in Fig. 1, the gun is raised. When the gun is to be lowered, the clamp 77 is moved upward on the leg 00 toward the head 71, and the chain 78 is thus slackened, allowing leg 00 to be swung away from legs y as far as desired. A seat V is mounted on the rear leg at, its front end being supported on the leg by clamp 126 and its rear end by link 127, connected to clamp 128 on the leg w. The seat may thus be adjusted to any desired position of use by moving the clamps 126 128, or the seat and link 127 may be closed against the leg :1; for packing.

The operation of the gun will be understood from a brief general descriptionin connection with the description of the parts heretofore given and the drawings, referring also to Letters Patent No. 584,153.

Assuming that the parts are in the position shown in Fig. 2 and that the gun has just been discharged, the recoil carries the barrel A and barrel extension B rearward together to the limit of the recoil movement, as shown Thein Fig. 3, the breech-block O moving with the barrel and barrel extension B. This movement of the barrel and barrel extension forces the lever f backward bodily by the connection of the upper end of the lever to thebarrel extension B and the connecting-link 31 between the lower part of the barrel extension and the leverf. The leverf is thus moved back until the sear it engages the tooth 10 in the catch-block 44, and the spring 38 isthus compressed against the head 40 by the plates 9 g moving back with the lever f. During this movement the links K L are held in normal position and the breech-block 0 locked to the barrel by the pin 27 moving in slot 60 andthe straight portion of slot 28, so that the barrelextension B receives the full force of the recoil. YVhen the force of the recoil is expended and the barrel free to return, the spring 38 will recoil, and as the lever f is held by the sear 7L and tooth 10 of the catch-block 44 the leverf will be operated as a lever with its fulcrum at the pivot 43 and the lower end thrown forward and its upper end rearward as the plates g g are returned by spring 38 toward their normal position, and by this action the lower end of the leverfactuates the barrel extension B through link 31 and returns the barrel to its normal position, at

the same time throwing backward the upper end of the leverf to throw back the hammer e, which is connected thereto by pin 30. The pin 27 of the hammer e travels in the straight portion of the slot 28 for a short distance during this movement and then enters the inclined portion of the slot and breaks down the links K L, and the link L is then actuated as a lever with its fulcrum at 25 and the power applied by the pin 27 and through the link K, connecting the other end of this lever L to the breech-block 0, draws the latter back to open the breech as the barrel reaches its normal position. \Vhen the breech-block is nearly withdrawn and the barrelis nearly returned'to position, so that the breech is open for the discharge of the shell and the insertion of the cartridge, the forward end of the ejector b strikes the head of the cartridge shell held by the extractors a and forces it IIO out of the grasp of the extractors and down and out of the opening 15 of the frame D. The parts are now in the position shown in Fig. 4. During these operations of the different parts the magazine-actuating leverJ has been moved by the plate g, lug 93, and finger 91 of the lever J from the position shown in full lines in Fig. 2 to the position shown in dotted lines in the same figure and in Fig. 3, and the pawl 97 of the plate 1 thus moved backward into position to engage a tooth on the ratchet 9b, which occurs when the parts areas shown in Fig. 3, the position of the lever J at that time being shown in dotted lines in this'figure, the lug 93 running under the finger 91 during the latter part of this movement, so as to lock the lever J in position. Fig. 13 shows this position of the pawl. As

' down the links K L, to withdraw the breech bolt from the barrel and open the breech, as previously described, and to bring the parts into the position shown in Fig. 4, the forward movement of the plate g carries the lug 93 from under the finger 91 and into position to engage the finger 92, as shown in dotted lines in Fig. 4, but does not actuate the lever J. During this movement of the breech block the cartridge that has entered the openings 99 16 and is then in the position shown in full lines in Fig. 12 lies upon the top of the breech-block, and the spring 101, which has been put under increased tension by the backward movement of the plate I, as above described, presses the curved-surface guide 103 so as to tend to force the cartridge downward. As the breech-block reaches its rear position and the breech is fully opened the support of the cartridge by the breechblock is withdrawn and the cartridge passes down through opening 16 into the position shown in Fig. 5, in which it is supported throughout the rear portion by the plates .9 and at the point by the support or rest 106. The cartridge is moved downward through opening 16 not only by gravity, but by the pressure of spring 101 upon guide 103, so that the latter acts to force the cartridge down with a quick spring movement. The guide 103 is thus moved over theopening 99 and into the position shown in Fig. 13, so as to close the opening, but yield, as before described, for the feed of the next cartridge. The barrel is now in normal position, the breech fully open, and a cartridge in position for loading, the next movement being for the return of the breech-block to close the breech. The sear -h is now rocked upon the point of the pin 12, resting in the notch 13 on block 44, so as to raise the sear-hook out of engagement with tooth 10 on block 44 against the tension of spring 45, and as the sear-is released from the tooth 10 the spring 38, acting through the plates 9, g upon the leverf, rocks the lever f forward upon the pivot formed by its connection to the link 31, the connection of the link 31 to the barrel extension B being now stationary, as the barrel has returned to normal position, and the hammer e is thus moved forward by the upper end of the lever f, so as to swing the links K L upward by the pin 27 acting in the slot 28 in link L, and thus open the links and return the breech -block to position to close the breech, the breech-block during this movement engaging the head of the cartridge and moving it forward into the barrel, with the extractors grasping the rim of the cartridgeshell, as usual. The position of the parts with the breech-block 0 partially returned and just engaging the head of the cartridge supported by the plates 8 to move it forward into the-barrel is shown in Fig. 5. During this return movement of the breech-block the sear-hook moves over the top surface of the catch-block 44, between the catches 1O 11, and is pressed downward by the spring 45 into position to engage the catch 11 and hold the hammer a back from the forward end of the slot 28, so as to permit a slight forward movement of the hammer suflicientto actuate the firing-pin for the discharge of the gun when the sear is released from the catch 11, as previously described. When the breech-block has been fully returned to position to close the breech, the breech-block is locked in position by the pin 27 in the straight portion of the slot 28 and all the parts are in the position shownin full lines in Fig. 2, except that the hook of the sear h is in engagement with the forward catch 11 of block 44, and the hammer e and upper end of the lever f are thus held back correspondingly, as indicated in dotted lines in Fig. 2. During this return movement of the breech-block the lug 93 engages and actuates the finger 92 of lever J, and thus rocks the lever J from the position shown in Figs. 3 and 4 to that shown in full lines in Fig. 2,which movement of the lever J, through the projection 95,actuates the pawl 97 to move from the position shown in Fig. 13 to that shown in Fig. 14, and thus rotate the holder N to carry a cartridge over the openings 99 16, and this cartridge then falls and is pressed downward partially through these openings by the guide 103 and into the position shown in full linesin Fig. 2, restingupon the breechblock. The parts are now in position for the discharge, and upon the pulling of the trigger Z the tripper 48 will be swung upward and the sear 77. released from the tooth 11 by the tripper-arm 5, when the spring 38, which has been held from full return by the engagement of the sear h with the catch 11, will rock the lever f forward from the position shown in dotted lines in Fig. 2 to the position shown in full lines in the same figure, and thus through hammer 6, bars d (Z, and pin 0 explode the cartridge, when the operation above described will be repeated.

The abovedescription applies to the operation of the gun in single firing, with the plate 53 moved down on the trigger Z into the position shown in the drawings, so as to uncover the opening 9 and prevent the movement of the pin 7 by the trigger. The operation in continuous firing is the same except that the plate 53 is moved upward on the trigger to cover the opening 9, so that the pin 7 is raised by the engagement of the plate 53 therewith repeated as long as the trigger is held back until the cartridges in the magazine are exhausted.

To load the gun by hand, the handle end of the hand-lever H is thrown forward, thus moving the upper part or fork of the handlever H rearward to engage the pin 29 of the hammer e and move the hammer rearward, thus rocking the lever frearward upon its pivot to the link 31 to break the links K L downward and withdraw the breech-block'to open the breech, this movement also withdrawing the plates 9 g, so as to actuate the lever J and cartridge-holder N to feed a cartridge in the same manner as previously described, and the hand-lever H is then thrown rearward to move thehammereback and move the breech-block forward to close the breech, the sear h then engaging the catch 11 on block 44 to hold the hammer cooked in the same manner and the cartridge being carried into the barrel by the returning breech-block, all

as previously described. The hand-lever is thus operated without compressing the spring 38, as the spring 38 bears against the head 40 of the handle-lever bars 41, and this head 40 moves with the handle-lever H, so that the tension of the spring 38 is thus equ'alizedby .the corresponding movement of the head 40 and the plates g g in the rearward movement of these members, while the head 40, acting upon the spring 38, pulls the plates g g forward to actuate the lever f and close the breech as the hand-lever is returned to normal position. It is obvious from the drawings that the hand-lever is locked in normal position when fully returned by the bars 41 and head 40 abutting against the spring 38. The hammer may be uncocked by hand by throwing the hand-lever H so that its upper end by engagement with the pin 29 holds the hammer a back against the tension of spring 38, then pulling the trigger to release the sear h and allowing the hammer to move forward against pressure on hand-lever H.
