11 Claims.

'The invention relates toimprovements in machine gun ammunition supply and feed apparatussand has for an object the provision of Vmeans for readily positioning a supply of ammunition in association with a machine gun and for effectively guidingand feeding the ammunition tothemachine gun.

. f Another object. is to provide a feedchute or vfeed-Way assembly which is of simple and easily assembled construction and Which is adapted to y lbe fixedly mounted' upon the gun cradle structure AV further Objectis the provisionof mounting means on the gun cradle structure in association with thel feedvvay assembly-v for removably' supporting anammunition box. Another object'Y is to. provide a novel and effectivelatchmechanism provid-ing for rapid positioningrand removal' of the ammunition box.

A further-Objectis to4 provide means for quick loading of'machine guns', such as the Browning type of' machine guns, Withoutv the necessity of handlingthe. ammunition belt', nor of opening thecoverf of the gun in. order to Vplace the loaded n belt. properly intoY the belt opening of the gun.

`A .still further object is to provide means mountingthe ammunition box; in a substantially balanced: position substantially half above. and

Referring to the drawings, an` ammunition container or box I is provided, containing a supply of ammunition preferably in thel form of' a metallic link belt of cartridges 2. The box is mounted on a bracket 41 which is secured by bolt means 6 to a support plate 66, and which in. turn is bolted to the lugs 9a of the gun cradle 9 at 61. B8, 69, and 10, the support plate being provided with holes at thesepoints for the purpose; The belt of. cartridges discharges from a lateral opening 4 near the top of the box, into the mouth 5 of the feed chute 3, which cooperates with the feedopening T of the machine gun 8.

The feed chute 3 is also mounted upon the support plate 66 which is secured to the gun cradle 9, with the discharge end I0 of the feed chute in operative position to discharge into the feed opening of the gun 8. A desirable fixed mounting of the feed chute upon the support plate 66 which is fixed to the gun cradle, consists in the anges II on the feed chute or feedway assembly 3 having openings I2 therein for alignment with corresponding openings I3 in the support plate 66 with securing means such as bolts i4 in said aligned openings.

A. sprocket or star wheel assembly is-mounted inA bearings I5 in the upper part of the feed chute assembly 3 and comprises an axle H5 received in said bearings I5 and a sprocket or star wheel member Il receiving said axle andsecured on saidaxle by pin means I8 or the like. The pin means I8 may desirably be held in place by a removable clamping means I9 having resilient fingers 2!) which clamp around the central portion of the star wheel member. The sprocketY or star wheel member Il preferably is provided .with spacedapart sprocket or star wheels 2l, one of larger diameter than the other for receiving and moving the belted cartridges of .theammunition supply fromthe exit opening i of the ammunition box` I into the entrance opening 5 of thev feed chu-te 3, the. sprocket memberk I1 isrotated the . plate 66 secured to the gun cradle, and a feed chute cover member 3a pinned to the apertured v ears 23 o-f the main feed chute member 3 by means f of a pin 24 extending through the upper end of the cover member 3a and through the apertures of said ears, and held in place by cotter keys 25 in l the ends of the pin. Lateral projections26 of the cover are slidably received in slots 2l provided in the side members 28 of the main feed chute member 3.

At the lower end of the feed chute cover there is provided a roller assembly comprising a roller receiving recess 29 in the lower end of the feed chute cover 3a between arrn members 30 having openings 3l thereinY receiving the roller shaft 32. The roller shaft is secured in the feed chute cover by pins33 extending throughl the arm members 30 and through the roller shaft.y lThe roller 34 may desirably be of metal or other suitable material and is rotatively mounted on the 'roller shaft 32 so as to be capable of sliding axially thereon. Bumpers 35are provided on the roller shaft within the opposite arm members l.'-36 of the feed chute cover 3a on either side of the roller 34 and normally spaced from said roller,

ybeing preferably of rubber or like resilient ma- Aprojecting partly into the feed opening 'l of the gun to guide the cartridges into the gun. The resilient fingers permit the belt of cartridges to move with the recoil and counterrecoil motion of the gun during firing. The resilient, fingers or guide blades 36 may desirably be of Spring metal. They are preferably curved to conform'to the feed chute and extend from a point of attachment in the upper portion of the feedway assembly and may desirably be secured at their upper ends to the main feed chute member. The upper ends 31 of the fingers or 'guide blades are turned over and receive pins 38 passing therethrough and seated in outwardly extending apertured ears 39 of the main feed chute member 3, openings 4U being provided in the sides of the said member for receiving the turned over ends 3l of the guide blades or fingers. l

Liners 4l and 42 of suitable material such as spring steel are secured Vwithin the main feed chute member and the cover, by means of rivets 43 or the like. VThe liner 42 for the cover is pro'- vided with a turned over part 44- which embraces the upper edge of the cover and is riveted through.

The gun feed opening I is provided with a feed pawl 46 and a retaining pawlV 45'.

At the upper ends of the side walls of the ammunition box bracket 4l notches 48 are provided -for receiving lugs or pins 49 projecting `from. the

'out of connection with the bracket. Y Vmeans 59 are provided between the side wall of provided with an inturned lip 53, providing surfaces inclining inwardly and downwardly for sliding reception of correspondingly inclined projections -54 on the oppositeksides 50 of the ammunitionV box. The inclined lips 53 on the bracket arms constitute retaining means for the box requiring the box to be lifted for removal from Ythe bracket. v

The bracket 41 is provided with a latch 5571101' retaining the box in position in the bracket, the latch being pivotally mounted to the side of the bracket and vcomprising a detent portion 56 below the pivot 5] for engagementwithV the'upper surface 58 of the projection 54 on the side of the ammunition box to retain the box in posi-,- 73; Y,

tion in the bracket by preventing its being lifted Spring the bracket'and the upper part 6llof rthe pivoted latch for urging the latch into box retain- .ing position. `Thelatch is pivoted at thefinsideV of theside wall of the bracket vand is desirably j provided with an operating handle portion. 6I or iingertpiece inthe formof a, bent extension embracing the vfront edge 62 of the sidewall of the bracket and providing a stop properly Dositioning the latch in operative vpositionamd lim- -iting its movement underthe spring action. rlhe latch is released by moving the upper partj thereof outwardly against the spring action which swings the lower or detent .portion v56 inwardly away from the projection 54 on the side of the box, so that the box may be removed from the bracket by lifting the box upwardly. j

The inner wall of the ammunition box is shaped inwardly of the box providingy a :recess 63 to enable the wall of the box to clear portions cartridge exit. A spring-pressed retaining Da fwlY V65 is vprovided in the top of the ammunition box for engaging the cartridges in the exit opening of the ibox and preventing the ammunition belt from slipping backinto the box wl'lenither beltv is not engaged and retained by the belt holding or retaining pawl 45 on the gun. TheV pawl 65 yields upwardly about its pivot infeed- .ingmovement of the belt but retains the cartridge belt against retractioninto the box.

' The special latch `mechanism permits rapidV positioning and removal of the ammunition box.V When the box is latched into position, the exit openingv is in operative communication with the feed chute entrance opening. Y

The ammunition box and its supporting bracket are so disposed that the box is mounted'in a balanced position on Athe gun substantially half above and half below the center of the elevation trunnions substantially onl the center line' of the gun, to provide substantial equilibrium Vof the structure rotatably supported on the elevation trunnions in various angles of elevation.
