This invention relates generally to a gun feed mechanism and more specifically to a feeder and stripper mechanism for feeding ammunition to high speed guns.
Modern high speed guns operate at a very high rate of fire and it has been found that current ammunition feeding and stripping mechanism present inherent difiiculties in the delivery of linked ammunition for example such as link separation at the folds in a storage box as the belted ammunition is removed therefrom. The inertia in the belt travelling at high speed tends to spring the links at the folds releasing a round of ammunition and separating the belt with consequent disastrous effects under actual combat conditions.
Heretofore the extremely high rate of ammunition feed has not been entirely satisfactorily obtained even under the most ideal test conditions and under actual combat conditions it would appear impossible to in any way closely approach the rate of fire obtained under the ideal test conditions. One of the main drawbacks encountered appears to be the impracticability of feeding the firing mechanism from a single belt by existing systems so as to give the desired rate of rounds per minute.
An object of the present invention is to provide a solution to the existing problem of feeding a gun at a very high rate while at the same time eliminating drawbacks and failures of prior known devices. Broadly the present invention provides a device for feeding the firing mechanism of the gun from two or more belts of ammunition wherein the rate of travel of the belted ammunition is reduced in proportion until a rate of speed consistent with known satisfactory delivery is obtained both from the standpoint of the channels and the storage boxes.
Accordingly, an object of the invention is to provide a multiple feeder and stripper utilizing a series of two or more specially designed and formed sprockets mechanically connected and intermeshing in a manner to provide both a constant flow to input and output units. The mechanism is applicable to free, linked, belted or otherwise connected ammunition and is adapted for installation in and connection to existing gun mechanisms.
A further object of the invention is to provide a multiple feeder and stripper with an external feed or booster mechanism which can be interconnected with the driving mechanism of the gun to provide ammunition feed.
A still further object of the invention is to provide a mechanism in which link ejection can be incorporated at any desired position commensurate with the gun design.
Other and further objects and advantages of the present invention will be apparent from the following detailed discussion of embodiments of the invention taken together with the accompanying drawings, in which:
Figure 1 is a partial elevational view, partly in section, of a multiple feeder and stripper mechanism having four supply sources feeding a common firing mecha- IllSm;
Figure 2 is a partial view of an embodiment having two feed sources looking forward just aft of the feed sprockets;
Figure 3 is a view similar to Figure 2 looking aft just forward of the feed sprockets;
Figure 4 is a partial sectional view through the feed mechanism showing a cartridge therein and the double contact therewith, and
Figure 5 is a schematic diagram of the gear train shown: in Figure 4.
In the drawings, the existing gun firing mechanism is diagrammatically illustrated at It) in Figures 1, 2 and 3, with an existing guide cam 11. The present invention, as shown in Figure 1, comprises a casing 12 adapted to be secured to the existing mechanism 10 by any existing securing means such as screws 13 or the like. The existing feed sprocket center is shown at 14.
The ammunition as shown in the drawings at 15 is pre sumed to be linked Cal. .60 ammunition of a standard type carried by link belts 16 also of standard construction.
In Figure 1, four supply sources designated A, B, C, and D are shown leading from standard ammunition storage boxes. The casing 12 accordingly is provided with ammunition inlets at each of the four points A, B, C and D and with feed channels leading therefrom established by cam guide surfaces such as at 17, 13, f9, 20 which in conjunction one with another provide guide channels for the ammunition. In Figure 1 there are four initial guide channels 21, 22, 23 and 24. Guide channel 21 merges with guide channel 23 to form guide channel 25 and guide channel 22 merges with guide channel 24 to form guide channel 26. Guide channel 25 and 26 then merge into a single final guide channel 27 which then feeds into the gun firing mechanism.
As can be seen in Figure 1, the ammunition feeding from the four supply sources simultaneously is brought to a single output feeding into the firing mechanism. In order to feed the ammunition, a plurality of sprocket wheels having cammed spokes thereon are provided and which are driven from a single source by a gear train as will be set forth hereinafter. Sprocket wheels are provided of two types for contacting the cartridges at two spaced points as can be seen from Figures 2, 3 and 4. Sprocket wheels 28 have the spokes thereof shaped to contact with the rearward portion 29 of the cartridge and sprocket wheels 30 have the spokes thereof shaped for contacting the forward end 31 of the cartridge. The shapes and dimensions of the sprocket wheels are such as to provide proper contact with the cartridges and also for proper spacing in conjunction with the cammed surface forming the guide channels for the cartridge.
Also provided in the device are stripper cams .32 which act to strip the belt from the cartridges as soon as the cartridges enter the guide channels and the belts are thereafter discharged from link ejection channels 33.
In Figures 2 and 3 as set forth hereinbefore only two ammunition supply sources are utilized which feed into two guide channels 34 and 35 which subsequently merge into a single output channel 36. As seen from Figures 2, 3 and 4 the sprocket wheels interrnesh with one an' other. For example, sprocket wheel 37 is formed of two spaced plates having the spokes thereon, whereas dividual sprocket wheels are ke ed on their shafts by The individual shafts means of pins as shown at 41. are rotatably journalled in bearings.
From Figures 4 and 5, the drive for a device such as shown in Figure 2 is set forth. A gear 42 is operatively connected to the drive mechanism for example of the firing mechanism. Gear 52 is secured to shaft 43 by means of pin 44. This shaft 43 carries a gear 45 se Patented Dec. 19, 1957 ured. the eon. by P n. as so sp Wheels 38 d 40. Gear 45 intermeshes with an idler gear 47 rotatably journalled on bolt 48. Idler gear 47 engages with a further gear 49 secured on shaft 50 which is rotatably journalled and to which the sprockets 3-7 and 39 are secured by pins 41, Upon rotation, therefore, of gear 42, the shafts 43 and 50 are synchronously driven with respect to one another and therewith the various sprocket wheels.
The direction of rotation of the various sprocket wheels are shown by the arrows in the various figures of the drawing. The gear train for driving the various; sprocket wheels is shown in Figure 5, wherein there is also shown the sprocket drive means 51 and 52,
The; arrangement of coacting adjacent sprocket wheels as seen from the drawings provides that; a tooth or spoke of one sprocket wheel is interposed between adjacent teeth or spokes of the coaeting sprocket wheel and the spacing of these teeth or spokes is arranged to allow each of the sprocket wheels to coact with the cartridges being fed to it in the synchronous arrangement and to clear cartridges and teeth of adjoining sprocket wheels as will be apparent.
From the foregoing discussion of the figures, it is believed that the operation of the multiple feeder and stripper mechanism will be readily apparent. Due to this arrangement, the cartridges can be fed from a plurality of sources to a single firing mechanism with a commensurate decrease in the speed of movement of the ammunition belts thereby overcoming drawbacks and failures of known devices and insuring proper and adequate rate of feed to the gun to fulfill the requirements of the modern high speed firing mechanisms.
Obviously modifications will be apparent to those skilled in the art to which the present invention pertains without departing from the scope and spirit of the invention as defined in the appended claims.
