Patented Apr. 25, 1950 AMMUNITION BOX HOLDER George H. Collins, Lynn, Mass, assignor to United Shoe Machinery Corporation, Flemington, N. 3., a corporation of New Jersey Application July 1, 1946, Serial No. 680,578
This invention relates to ammunition box holders and is herein illustrated as embodied in a holder adapted to support ammunition boxes for automatic guns, more particularly the caliber .30 or caliber .50 Browning machine gun.
It is an object of the invention to provide an ammunition box holder so constructed as to permit easy and rapid attachment of an ammunition box thereto and its removal therefrom.
Another object of the invention is to provide an ammunition box holder adapted to accommodate ammunition boxes of different heights and types.
A further object of the invention is to provide an ammunition box holder adapted to lock the ammunition box securely on the gun to prevent its falling off during the operation of the gun.
These and other objects and features of the invention will become apparent from the following description with reference to the accompanying drawings, in which:
Fig. 1 is a view in front elevation of one form of ammunition box holder embodying the invention;
Fig. 2 is a horizontal sectional view on the line II-II of Fig. 1;
Fig. 3 is a vertical sectional view on the line III-III of Fig. 1, indicating a metal ammunition box secured to the holder;
Fig. 4 is a view in front elevation of a modified form of ammunition box holder;
Fig. 5 is a vertical sectional view on the line V--V of Fig. 4, indicating the metal ammunition box secured to the holder shown in Fig. 4;
Fig. 6 is a view substantially similar to Fig. 5, but indicating an ammunition box of a diiferent type secured to the same holder; and
Fig. 7 is a horizontal sectional view along the line Vl1-VII of Fig. 4.
In one embodiment of the invention, illustrated in Figs. 1, 2 and 3, the ammunition box holder is adapted to support a sheet metal ammunition box B, indicated by broken lines in Fig. 3, from which ammunition is to be supplied to the feed channel of a gun G, such as a caliber .30 or caliber .50 Browning machine gun, mounted on a gun support comprising a cradle C.
A mounting bracket I0 is rigidly secured, as by welding, to the gun supporting cradle 0 adjacent to the ammunition feed channel in the breech end of the gun. The bracket has a pair of forwardly and inwardly projecting vertical ribs l2 forming ways within which is mounted a plate M. The lower end of the plate [4 terminates in a U-shaped flange [6 adapted to engage a flange ii at the lower end of the wall of the ammunition box facing the gun, as shown in Fig. 3. The plate It is provided with a pair of rearwardly projecting ears it which engage the lower end of the bracket It to prevent upward movement of the plate relative to the bracket.
The plate [4 is further provided with a pair of inwardly turned vertical ribs 20 forming ways in which is mounted a latch member 22 provided at its upper end with a hooked portion 26, which is arranged to engage a hinge 26 on the wall of the ammunition box facing the gun and to cooperate with the U-shaped flange [6 of the plate It to lock the box in operative position. The latch member 22 is movable heightwise relatively to the plate It against the tension of springs 28 anchored at their lower ends to lugs 36 extending forward from the plate It and, at their upper ends, to a lug 32 projecting forward from the latch member through a rectangular opening 34' in the latch member. Downward movement of the latch member 22 relative to the plate It is limited by its engagement with a tongue 36 projecting forward from the bracket l0 through an opening 38 in the plate H.
To attach an ammunition box B to the holder just described, the hinge 26 on the box is placed under the hooked portion 2 of the latch member 22 and the box is pushed upward until its flange ll engages the U-shaped flange [5 at the lower end of the plate 14. As the box is being pushed upward the latch member 22 is moved upward relatively to the plate id against the tension of the springs 28, which are of such strength that the box will be rigidly clamped in operative position when the flange ll of the box and the flange B6 of the plate Hi are interlocked.
By reason of the spring connection between the latch-member 22 and the plate M, the latch member is self-adjusting to accommodate ammunition boxes of various heights.
To remove the ammunition box 13 from the holder, the box is pushed up until its flange I! is disengaged from the flange it of the plate 14, whereupon the box is tilted to free its hinge from the hooked portion 24 of the latch member 22. Upon removal of the box the latch member 22 is returned to its initial position by the springs 28.
Figs. 4 to 7 illustrate a modified form of ammunition box holder adapted to support either metal or wooden boxes for caliber .30 or caliber .50 ammunition.
This holder comprises a plate 49 having a pair of rearwardly extending vertical ribs il, which fit in guideways formed in a mounting bracket 3 42 secured to the gun cradle C adjacent to the feed channel in the breech end of the gun. The bracket 42 is provided with forwardly and inwardly extending vertical ribs 43. The lower end or" the plate 40 terminates in a U-shaped flange G4 which is arranged to be engaged by the flange ll on the lower end of the rear wall of the metal ammunition box B, i. e., the wall facing the gun, as illustrated in Fig. 5. In the spaces between the ribs 4! and the walls of the guideways in the l mounting bracket 42 are inserted metal strips 45, the upper ends of which are bent outward over the upper ends of the mounting bracket and the lower ends of which are bent inward over the lower ends of the ribs 4! to lock the plate 40 against downward movement relative to the mounting bracket.
Also mounted in the bracket 42 is a latch slide QB which is movable heightwise relatively to the plate 40 during attachment and removal of a metal ammunition box. Downward movement of the latch slide 48 relative to the plate 48 is limited by engagement of the slide with a forwardl projecting tongue 48 on the plate 41}. The tongue 48 abuts against a projection 53 on the lower end of the mounting bracket 42 and prevents upward movement of the plate 40 relative to the bracket.
The latch slide 46 has lugs 52 extending rearward through an opening in the plate 4%. The lugs 52 provide bearings for a rockshaft 54 extending lengthwise of the gun. Rigidly mounted on the shaft 54 is a latch member 55 having at its upper end two hooked portions 58 arranged to engage the hinge 26 on the box B, as shown in Fig. 5, and to cooperate with the flange 4 of the plate 49 to lock the box in its operative position. The hooked portions 58 of the latch member extend forward through openings 60 in the slide 46 and through an opening 62 in the bracket 42. The latch member '56 is yieldingly connected to the plate 46 by springs 64 secured at their lower ends to lugs 66 extending rearward from the lower end portion of the plate 40 and, at their upper ends, to a cotter pin 68 anchored tothe latch member 56.
To attach the metal box B to the holder just described, the box is presented with its hinge 26 under the hookedportions 58 of the latch member and pushed upward; As the' box is pushed upward, the latch member 56 and the slide 46 are moved upward, against the tension of the springs 64, until the flange ii at the lower end of the box engages the U-shaped flange 44 at the lower end of the plate 40, whereupon the box is clamped in operative position, as shown in Fig. 5. The box is removed from the holder in the manner described previously in connection with the holder illustrated in Figs. 1 to 3.
The manner of attaching a wooden ammunition box, such as the box B illustrated in Fig. 6, is somewhat different from that previously described in connection with the metal box. The wooden ammunition box has no flange such as the flange ll of the metal box but, instead, is provided with vertical grooves '10 (Fig. 6) in its side walls, and the lower portion of the rear wall facing the gun is cut at an angle and recessed to provide a ledge '12. To attach the wooden box to the holder, the ribs 43 of the mounting bracket are caused to engage in the grooves 10 of the box and the box is moved downward until the ledge 12 seats against the projection 50 on the bracket. During the downward movement of the box, the engagement of its rear wall with the hooked portions 58 of the latch member 58 causes the latch member to swing inward. The above procedure is reversed to remove the box and, as the box is freed from the holder, the latch member 56 swings back to its initial position.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. An ammunition box holder comprising a bracket, a plate mounted in said bracket and having a box-engaging portion adapted to engage the lower end of a box of one type, yielding latching means mounted for heightwise movement relative to said plate and also for swinging movement about a horizontal axis, said latching means having box-engaging portions adapted to engage the upper end of said box and to cooperate with the box-engaging portion of said plate to clamp the box in operative position, means on said bracket adapted to support a box of a differ-. ent type, and spring means connecting said plate and said latching means and against the tension of which said latching means efiects its heightwise and swinging movements, whereby the latching means is rendered self-adjusting to accommodate boxes of difierent heights and types.
2.
