Patented .Tune 2, 1908 To all whom 'it may concern:

Be it known that I, BENJAMIN F. LANG- DON,. of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Firearms; and I- do hereby declare that the following is a full, clear, and exact descri tion thereof7 which will enable others skille in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference ed for firearms handlinfg has numerous points o marked thereon, .which form part of this speclcation.

My invention -relates to improvements in Ifirearms, and more particularly to the magazine and the manner in which it is arranged to handle cartridges and to coperate with the barrel and working parts performing its function. Y v

This invention is more particularly adaptsmall cartrid es and utility as will ereinafter more fully appear.

Flg. 10 shows details partially 1n sectlon of bottom view 0f the rearend of the magazine tube. Fig. 12 is a'partialview of the rear end of the stock with the magazine closure or cover in open position. v

Referring t0 the reference letters and figures in a more particular description, 1 mdlcates the barrel which is extended rearwardly and chambered to a larger diameter in the part -1a which constitutes practically `mer) is provided Wit Fig. 11 is a partial at the rear end. The stock 3 is extended forwardly under the barrel and is secured thereto by a screw or bolt, the barrel and receiver portion 1a thereof lying in a groove cut in the u per side of the forward end of the stock.

e receiver portion is rovided on top with an opening 5 through W ich the empty shells are ejected and through which access may be had for other purposes, as will hereinafter appear. This opening is made by a cross cut across the to of the ba-rrelfsufliciently dee to enter well into the enlar ed o ening Whic receives the bolt 2. The reec bolt is of a tubular form asshown except the front end, which is provided with a sectionv2a of truncated cone form.

They vtubular portion of the breech bolt receivesthe firing pin 6, which is itself hol- `low or tubular in the ymain part, and rethe walls of the firing) pm and supported'in the rear end of the reech bolt. ward endof the firing1 The forpin (otherwisehama rojecting pin 6b which is' adapted to be projected through an o ening in the forward end of the bolt and is t e partwhich strikes the cartridge to explode the' same. The rear end of the firing pin may be provided with a knob 6, which will afford means for. manually operating the firing pin and close the rear end thereof and give a finished a pearance thereto.

The combine trigger and bolt stop 10 is pivoted at 11 in the frame art and 1s provided at its forward end wit a catchV shoulder 12 adapted to catchl the forward endof the firing pin and hold it'against the tension of the sprmg 7 when not disengaged therefrom. The forward end of the trigger and bolt stop 10 is ada ted to strike on a shoulder 10a of the breec bolt and limit-the opening movement of the bolt. The bolt is cut out on the underside, as indicated at 10b, to permit its rotation in locking and unlocking without interfering with the forward end of the trigger 10 and to enable the trigger to engage with lthe forward end of the firing in.

t 1s also slotted, as indicated at 10, to a ow the Ibolt to be Withdrawn to a sufficient extelit to open the breech before theforwad end of the trigger engages with the shoulder 10a and limits the opening movement.

TheA breech bolt is -provided with a handle the shock of the explosion.

12 by means of which it is mani ulated, the shank or base portion of the han le adjacent to the bolt being adapted to enter an L- sha ed recess 14 in the rear end of the frame, an( when turned into proper position, lock the bolt in closed position and so as to resist The trigger and bolt stop 1() is operated into securing osition by the sprin 15 and is provided wit the usual projecting ever portion 10d to receive the finger of the operator to actuate the same.

The magazine consists in the main of a tube 16 which passes through an opening in the stock 3 from the butt plate to'the rear end of the barrel and is jointed at 17 so that the forward end is flexible and may be moved into and out of line with the rear end of the barrel. For moving the forward end of the magazine into line with the barrel, there is provided a spring 18 which tends at all times to throw the forward end of the magazine up into line with the barrel. The forward end of the bolt 2 is adapted to ride the forward end of the magazine down against the tension of the spring 18 and move it out of line with the barrel and occupy that ositionitself. The joint 17 is arranged well ack from the rear end of the barrel, whereby relatively sharp turns for the cartridges are avoided, particularly when the delivery end of the magazine is in register with the barrel. The forward end of the magazine occupies a osition in an opening in the underside of the rame immediately below the opening 5 before mentioned, and-at the rear end of the barrel proper; and when the breech bolt is in open osition the forward end of themagazine rises up into said opening and when the breech bolt ,is closed, it is forced down and more or less out of said o ening and into a suitable recess in the stoc Vimmediately below the opening. The rear end of the 'barrel is provided with a-downwar'dly projecting tang or plate 19, which is adapted to practically close the front end of the magazine when in its lower or depressed osition. The magazine 16 is provided wit a flexible follower 20 in the nature `of a clo'se coil spring,- the same being dprovided on one end with a head 20 adapte to engage the cartridge and secured atthe other end in a flanged or headed socket 20". The follower 20 is impelledl to- Ward the delivery end of the magazine b a spring 21. The s ring 21 with the soc et 20b is received wit in the ma azine follower tube 22, the forward end of w ich is slightly closed in so that the flan e of the socket 20b will enga e therewith an prevent the socket 20 with t e spring 21 from escaping through the forward end of `the magazine follower tube. The magazine follower tube is received in and fits in the magazine tube 16 and 1s provided at its rear end with a'plate piece 22* firmly secured thereto.

In connection with the tubular magazine 16, which, for the purposes of description, may be termed the primary magazine, there is provided also an auxiliary magazine 23 which is of tubular form and lies side by side with and extends parallel along the primary magazine for a sufficient distance where it communicates at its delivery end through an opening with and into the primary magazine. The length of the magazine tube 22 is such that when in position in the magazine 16 it will close the passage from the auxiliary to the primary magazine. Both the primary and auxiliary magazines may be supported at the rear by a plate 24 provided in a recess in the butt end of the stock, through which plate 24 the rear end of the primary and auxiliary tubes ass and also register with an opening in the utt plate 25.

In order to prevent longitudinal movement of the primary and auxiliary magazines inthe plate 24 these twoparts will preferably be provided with stops 24a and 24b engaging with the plate 24. secure the magazine follower tube 22 in position in the primary magazine while the follower is pressing on the cartridges which may be contained in the forward end of the maga- V zine tube, the follower tube 22 is provided with adpin or projection 26 ada ted to be receive of the magazine'tube, which projection 26 is particularly adapted to engage with shoulders 27l and 27b in one wall of the spiral groove.

Mounted on the plate 24 is a spring 30, the forward free end of which operates through an opening in the side of the tube 16 and is adapted to engage with the depressions or shoulders 31 and 32 in the magazine follower tube 22. When engaged with the depression 31, the spring 30 is ada ted to maintain the tube 22 against other t an forcible rotation while the projection '26 is in engagement with the shoulder 27. When engaged with the depression or shoulder 32, the spring 30 is adapted to maintain the follower tube 22 against other than forcible rotation while the projection 26 is engaged with the shoulder 27h. The spring 30 is also adapted to engage with a shoplder 33 provided on the forward end of the follower tube 22 and prevent the entire withdrawal of this tube from the magazine tube 16. 4The shoulder 33 will' preferably be provided so as to not entirely encircle the tube 22, whereby at one point by rotating the tube 22 into suitable position the spring 30 can be forced back and the follower tube entirely withdrawn.

The plate 22 on the rear end of the follower tube not onl serves as a handle to manipulate the fol ower tube by, but also as a closure for the rear end of the auxiliary magazine when turned into a ,vertical position. l

in a spiral groove 27 in t e rear end.

In order to to end position. In case these cartridges in- Fig. 1'.

tridge chamber, and in troduced in the auxiliary magazine are desired in the primary magazine, the follower tube 22 is rotated sufficiently' to disengage the projection 26 from the shoulder 27b and drawn out until sto ped by the spring 30 engaging on the shoullder 33. When so drawn out, the passage from the auxiliary magazine l into the primary magazine will be unob.

structed and the cartridges in the auxiliary magazine will readily pass by gravity into the primary one. When this has occurred, the magazine follower tube 22 will be forced back until it is caught and secured on the shoulder 27h. This closes the passage from the auxiliary to the primary magazine and a second lot of cartridges can then be introduced into the auxiliary magazine and confined therein by turning the plate 22a into proper position. `The cartrid es in the primary magazine may not only ll the portion 'j y. of the same which is in advance of the forward end of the follower tube, but they may also extend back into the follower tube, the opening in the forward end of the follower tube being suilicient to allow free passage of the cartridges in or out therethrough.

When the breech bolt is in open position, the forward end of the magazine will be raised by the spring 18 in line with the carcase the cartridge chamber is em ty a cartridge will be pushed into the cham er. When the breech bolt is closed the'forward end of the magazine Will be forced down into the position shown in The breech bolt will beA provided with an extractor 35, which, as the breech bolt is opened, engages with the cartridge shell and withdraws the same. The shell will be flipped out by the forward end of the magazine as it rises, or a projection 36 may be provided on the top of the forward end of the -magazine which will engage the lower edge of the cartridge head, and,coperating wlflitli the extractor 35, eject the cartridge s e The forward delivery -end of the magazine will referably beA curved and formed so that the orwardmstcartridge in the magazine will occupy a position substantially parallel with the cartridge chamber, and so as to form also what is practically amovable bottom for the o ening 5 in the frame of the firearm. The elivery end of the magazine may also be slotted, as indicated at 37, at its forward end whereby a pointed instrument may be inserted, if necessary, to move the cartridges in case of their becoming jammed or their passage interfered with by dirt or other obstruction. 1 The gun can be operated as a single loader Without using the magazine by the operator placing the cartridge on the top of the end of the magazine and forcing the magazine down against the tension of the spring 18, and then slipping the shell forward into the barrel chamber. It will also be noted that cartridges of sundry lengths may be promiscuously used in this ma azine, such, for instance,V as 22 caliber s iort, 22 caliber'long and 22 caliber long rifle when the gun is arranged for 22 caliber.

The joint 17 in the magazine tube may be vomitted and the magazine tube hinged at its rear end' at or adjacent to the plate 24. This construction, however, is deemed inferior to the one illustrated, in that the recess in the stock to provide therefor materially cuts the Way and weakens the stock, and the size and weight of the movable parts are much i'ncreased.y

What I claim as new and desire to secure by Letters Patent is:

1. The combination in I and with a :lirearm of a tubular primary magazine and a l tubular auxiliary magazine .substantially parallel with and arranged to discharge into the primary magazine, means for retaining cartrid es in the auxiliary magazine and means or feeding the cartridges to the firing mechanism provlded in the primary maga# zine, substantially as set forth.
