This invention relates to an ammunition clip of the en bloc type arranged to hold a stack of cartridges preferably in double row staggered relation and adapted to be ina sorted or charged therewith into the receiver of a gun. 4 In its general aspects, the present clip is of the character shown in my prior applications Serial No. 383,030, filed August 2, c 1929, and Serial No. 385,608, filed August 13, 1929; and the present improvement has to do more particularly with features of construction for such a clip whereby it will rest securely in the gun and firmly hold its 5 stack with a small amount of frictional engagement to permit the easy feeding of the cartridges therefrom.

A further feature of importance in the present clip is the provision of means to predetermine the correct filling of the clip with cartridges so that the higher row of the stack will always be in proper position for (reacting with the feedin follower of the gun. This feature of theinvention pertains to the double row staggered character of the stack wherein one row stands vertically higher than the other and a stepped follower is employed to feed the cartridges, as shown in my Patent No.- l,737,974i, dated December i 3,1929.

Other features of advantage in the present clip will be apparent from the following description and accompanying drawings, in which: 7

Fig. 8 is a sideelevation of a clip with certain modifications therein over that shown in Fig.. 1;

Fig. 9 is a front viewpartly in section along line 9-9 of Fig. 8.

Referring more particularly to the drawings, the clip is adapted to be made of a single piece of sheet metal stamped and die pressed into shape so that its cost of production will be low. The clip comprises a back plate 1 with forwardly converging

side walls

2 and 3 extending from said back plate for a considerable distance so as to engage thecartridges well forward from their bases and to embrace the contained stack. The clip is designed to receive and hold a double row stack of cartridges in staggered relation and the side walls of the clip are preferably of spring metal so as to exert a compressing action on both sides of the stack. The cartridges C are slightly tapered so that the 70 embracing action of the spring sides in combination with the base engagement of the cartridges, as hereinafter described, will hold the double row stack firmly and securely.

The present clip is of the reversihle type, that is similarly constructed both at its top and bottom ends so that either end may be introduced downwardly into the receiver of the gun and the other end will serve as the top of the clip for presenting the cartridges to the bolt for loading. Cut out

portions

36 and 37 in the back of the clip serve to permit travel of the bolt therethrough in loading the cartridges as described in my Patent 1,737,- 974' The back plate of the clip has a straight as transverse section but is slightly curved vertically.,as shown, and it will be understood that the rear wall of the n receiver will be correspondingly curved or the reception-of the clip. Each of the

side walls

2 and 3 is on formed at its upper and lower end with an inturn'ed portion or car such as d, 5, 6 and 7. In the form of clip shown in Figs. 1 to 4:, inelusive, the ears 4: and 7 are slightly nearer .Ltogethe'r in a diagonal direction across the 95 clip than the other ears 5 and 6. Another way of stating this is that each pair of ears (vizA and 6 or 5 and 7) at the same end-of the clip have a slight displacement vertically as regards their cartridge engaging portions. V"

This vertical displacement distance is indicated at w on Fig. 2. The diagonal distance between ears 4 and is indicated at 3 and the diagonal distance between ears 5 and 6 is indicated as 2. The distance 3 is slightly less than the distance 2.

By keeping the vertical displacement distance a; small as compared with the radius of a cart-ridge base, the clip is. constructed so that the loading of cartridges from the clip by the bolt may still be effected as described in m Patent 1,7 37 ,97 4. As therein disclosed, the olt picks off the top cartridge of the stack alternately from each row. While, as shown in Fig. 3 of the present application, cartridges on the right row will rise to a .slightl hi her osition a ainst ear 6 than y g P g ears 4 and 7 being less than that between ears 5and 6 requires thata full stack of cartridges -be filled into the clip with the higher row of the stack always on the right side, looking at the front of the clip as in Fig. 3. Afull stack could not be packed in the clip with the high row on the left side without forcibly distorting the clip out of its proper shape because of the insuflicient distance between the ears 4 and 7. Such forcible distortion of the clip out of shape would be a warning of its incorrect packing even in such cases where it could be accomplished and would ordinarily make the clip of unsuitable shape for insertion in the gun. The desirability of predetermining the aforesaid proper filling of the clip with cartridges is so that it maybe conveniently used in its reversible form with a stepped follower in the gun, as shown in my previous Patent No. 1,7 37 ,974. However, this particular feature of design in the present clip of having the ears arranged as de scribed may be readily dispensed with and said ears 4; and 7 may be spaced apart equal y with the ears 5 and 6 in which case the 6111) would preferably be used in combination with a follower having a shiftable step of the character shown in my copending application Serial No. 339,916, filed February 14, 1929.

The back plate 1 of the clip is formed with upper and lower outwardly projecting catch portions 8 and 9 adapted to engage with the suitable latchfof the gun as shown in my patent referred to for retaining the clip in the receiver. Each

side wall

2 and 3 of the clip is similarly formed and only one need be de-- scribed in detail. As shown more clearly in V 10 extends from near the bottom of the clip to near the top, and conforms in its lengthwise disposition to the curved back plate 1. It should be understood that the upper end of-the rib 10 stops short of engaging the flange F of the topmost cartridge in the stack. This is for the purpose of leaving said top cartridge free for easy loading by the bolt of the rifle in the usual manner.

Slightly in front of the rib 10 there is formed an outwardly projecting rib 11 which is adapted to engage behind a shoulder 12 in the receiver wall 13 of the gun. This latter engagement, duplicated as stated at the other side of the clip, serves to guide and position the clip properly in the receiver and also as a stop against any forward throw of the clip in the receiver. At the front edge of the sidewall 2 and about midway between sides of the cartridges at points well forward of the bases thereof. Near the upper and lower ends respectively of this vertical rib 17 are formed depressed recesses 18 and 19 as shown in Fig. 3 whereby an upper shoulder such as 20 is provided at recess 18 and a lower shoulder 21 at recess 19. Obviously the shoulder 21 will be in upper position and shoulder 20 in lower position when the clip is inverted. The similar recesses of side wall 3 are indicated at 2 2 and 23 and the corre sponding shoulders formed thereby at 24 and 25. The function of these shoulders will be understood from Fig. 3. When a full stack is in the clip the top cartridge C is in engagementwith the ear 6, and the bottom cartridge C is in engagement with the ear 5. The next to the top cartridge C which is held spaced from its adjacent ear 4 is in engagement with the shoulder 20 and this engagement is insuredby the lateral pressure of the ear 6 against the to cartridge C which throws it together with the cartridge C slightly to the left. This same action takes place at the bottom of the clip as respects cartridges C and C, and thus it will be seen that the diagonally dis osed cartridges C and C at the upper an lower limits of the stack, even though not engaged by the ears 4 and 7 are yet sufiiciently engaged by the shoulders and to avoid looseness in the confined stack. Furthermore, the

shoulders

20, 21, 24, and 25 when in upper position during a loading and feeding of cartridges act as stops respectively for the rising cartridge I of their respective rows and prevent angular movement of dislocation of the cartridge at the top of the lower row.

Referring to Fig. 3, it will be understood that after loading of the top cartridge C by the bolt in the usual manner, the cartridge C will readily ass its shoulder 20 into engagement with 516 car 4, (forced upward by the follower) and that cartridge C on the right will then rise to engage its stop shoulder 24. This action is repeated alternately-at each side of the clip throughout the loading and feeding of the cartridges.

It is desirable in a clip of this character to reduce its weight and to minimize as far as possible the frictional engagement of the clip walls upon its stack while yet furnishing a firm grip thereon to provide a tight en bloc packet when out of the gun. To this end, the

side walls

2 and 3 are cut away to a large extent and are formed as shown in Fig. 1 with

connectin bars

26, 27, and 28 between the rear and ront portions. The

bars

26 and 28 are continuations of the ears 4 and 5. The intermediate bar 27 is formed with an outwardly pressed middle portion 29 for stiffening the same and to provide inwardly proiecting ribs at each side thereof extending longitudinally of the clip, which furnish little or no contact on the cartridges as they rise vertically in the clip during feeding. The sides of the stack in the clip are firmly engaged near the cartridge bases by the inward- .y projecting ribs 10 and near the front by ;he vertical ribs 17, while-sliding friction )11 intermediate portions of the cartridges luring feeding is reduced to a minimum by he cut-away portions of the clip side walls ind the depressed portion of the bar 27.

Referring to modification in Figs. 8 end'9, he clip here shown is constructed similarly 0 that previously described, except that the

am

30, 31 at the top of the. clip and the ears :2, 33 at the bottom of the clip are not disalaced vertically. These ears are all at the ame distance from the symmetrical center of he clip. Furthermore, the cars and 33 lave inwardly bent tongue portions 34 and 5 of springy metal arranged as shown .to vrevent improper filling of the clip with artrid es.

In fil ing the clip all but the last cartridge my be inserted or laid in rather loosely.

At least it will indicate attempted and, therefore, cause a rearrangement of the cartridges in the stack so that the last cartrid may be smoothly inserted on top at the nght of the stackits proper place. The spring tongues 34 and 35 readily yield to the pressure of the rising cartrid es in the stack during the feeding thereof by the follower and under such pressure lie in the plane of their respective ear portions.
