CARTRIDGE CLIP Filed Jan. 14. 1928 2 Sheets-Sheet 2 Patented oci. 22, 1929 UNHTE STATES CARTRIDGE CLIP Application led January 14, 1928. Serial No. 246,82?. Y Y

This invention relates to a cartridge clip and has for its object an improved form ot' clip for holding a stack of cartridges en bloc in tight compact form and adapted to accompany the cartridges into the magazlne of a gun. A type of gun for which the present clip is particularly adapted is shown and described in my companion application Serial No. 197,718, tiled June 9, 1927.

The clip of this invention is of the expendible type,-that is, cheap enough in construction so that it may beithrown away after a single use it' desired; and is designed to Serve several purposes,namely, as a holder for the cartridges outside of the gun, as a retainer for facilitating the charging of the cartridges by hand into the magazine, and as a guide in the magazine to direct the cartridges into proper position for loading. A modified Jform of the clip as shown Will also serve to lubricate the cartridges preparatory to the loading thereof. In the present embodiment of the invention, I have secured these objects by the employment of a single integral piece of sheet metal or stamping,

bent into suitable conguration and possessing therequisite degreeof strength, springiness and lightness to'successfully accomplish the purposes for which it is designed.

The feature-in such a clip of being charged with the cartridges into the magazme chamber of the gun instead of having the cartridges stripped from the clip for charging, materially increases the rapidity of tiring possible in automatic guns. For the most-advantageous employment of such a clip, the gun should be provided with suitable means for discharging the clip automatically upon the exhaustion of its cartridges so that the gun may be ready 40 for rapid recharging. Suitable mechanism of this character for cooperation with the clip is shown in my companion application above referred to.

An important feature of novelty in the present clip is that it is designed to hold a stack of cartridges in double row and to impart a confining pressure upon said stack in such a manner as will hold the cartridges securely and firmly in fixed relation, i. e., inen bloc form under all usual conditions of han- (lling and ready for charging into a magazine. The confining pressure thus-afforded by the clip for holding the stack involves the balancing ot' both a vertical and lateral pressure upon the stack so as to maintain a uniform double-row arrangement of the stack. Preferably, when the clip is charged into a magazine chamber, the lateral pressure of the clip upon the stack is relieved by suitable coacting devices in the gun whereby feeding mechanisin Jf'or the cartridges may operate on a stack with less resistance to overcome.

Further advantages pertaining to details of construction will appear in the description which follows. The objects of the invention are obtained by means of the construction hereinafter described, and the scope of the invention will be pointed out in the appended claims. Referring to the drawings, which how a preferred embodiment of the invenion:

Fig. 3 is a rear end view of the cartridge 80 clip with the cartridges en bloc therein;

Fig. 4 is a front view of the same Fig. 5 is a top view of the same;

Fig. 6 is a horizontall section along line A-A of; Fig. 3 showing the 'action of the 85 cartridge retaining ribs; 5

Fig. 7 is a fragmentary vertical section somewhat enlarged along line B-B of Fig. 5 to show the upper termination of the cartridge retaining ribs; n

Fig. 8 is a view of the upper end of a modil fied form of clip containing lubricating pockets.

As shown in Fig. 1, the cartridges C held by the clip are of the usual tapered form and when closely packed in the clip are arranged to lie 'with the uppermost cartridges in substantially horizontal position ready for loading and with the underneath cartridges in positions of progressively greater inclination as they approach the bottom.

The clip is preferably a one piece-integral member of thin sprin metal or stampingcomprising a rigid bac 145 and two spring tensioned sides 146, 147 cut ont in places for lightness and suitably stiifened by upset deressions, or ribs. It should be noted that the epressed ribs 148 on the back are inclined to the horizontal and to the directionof feeding travel for the cartridges so that the base of the cartridges will not catch or foul therein. when being fed u wardly into loading position.| The clip itse f carries no feeding means as is the case with box-like detachable magazines; but suitable feeding means are provided on the gun for coacting with the present clip. As shown in Fig. 1, a spring actuated follower 159 is mounted on the gun for a travel through the clip in feeding the cartridges upwardly.

The back 145 and sides 146, 147 of the clip form in effect a receptacle for the cartridges open at the front, top and bottom. The sides 146, 147 tend to convergefrom the back 145 toward the front so as to impart lateral` --spring pressure against the stack of cartridges. At vthe bottom of the clip, the sides 146 and 147 have inwardly turned portions 147 of the clip and 4o or prongs 149, 150 respectively whichy are spring tensioned to press upwardly against the lowermost cartridges of a full stack to furnish a vertical pressure in holding the same securely and compactly. The taperedform of the cartridges enables the lateral and vertical pressure of the clip to compress the stack together into a solid unitary mass.

Adjacent the 4rear edge of each side 146, pr'oJecting inwardly are ribs 151 and 151 (see Figs. 'and 7) which serve as cartridge retaining ribs and in conjunction with the wedging action lof the tapered cartridges in the stack act to holdthe cartridges from slippingout of the clip while being handled outside of the gun and also to preventA any forward throw of the cartridges under the recoil impulse of firing. when in the magazine. These ribs extend from the bottom of the clip to a shortI distance from the top and the rib 151 onone side engages in front of the extracting rim of one row of cartridges while the rib 151 on the other side engages similarly'the other row of cartridges, as shown in Fig 6. The

ribs 151,151 donot -extend to the top of the clip and thereby leave the top cartridge free for loading, as shown in Fig. 7. These ribs do not extend vertically parallel with the back 145 of the clip but diverge therefrom `slightly toward-the bottom to allow for the increased linclination of the cartridges.

At the top of the clip, each side is formed with inwardly turned portions 152, 153 which are relatively stiff and serve to guide the uppermost cartridge as it is loaded into thegun chamber. The cut out portion 154 of the back allows the travel of the loading row and then from the other in loading the y same. .v

On the back of the clip is formed the 'outwardly offset locking nib 135 which is engageable by a suitable clip latch 132 for holding the clip in the magazine chamber. The clip latch 132 and its attendant operating mechanism forms no part of the present invention but it will be understood that said latch automatically engages the clip when charged into the magazine and at the proper time is operated to release the clip for its discharge. The nib 135 is located ofi' centerl or at one side of the center line of the back, and a. clearance groove or channel 155 is formed in the rear wall of the magazine chamber (see Fig. .2) vto receive this nib 135 when the clip is charged into the magazine. If any' attempt ismade to insert.,the clip upside down, the offset positionof the nib will prevent its introduction.

Each side of the clip at its front edge is formed with an inwardly depressed bump 156, 157 which, when the clip is introduced into the magazine chamber, will engage behind ledges 158, 158 provided on eachfside wall of the chamber, and thereby cause a spreading apart of the'y clip sides. In this way, the stack of cartridges, when in the chamber, is relieved from the lateral tension of the clip whereby the follower may feed the cartridges more easily.

In some cases it may not be necessary for the bumps 156, 157 of the clip in engaging the ledges 158, 158 of the gun to actually spread the sides of the clip apart, as it may be satisfactory for the ledges 158, 158 to .merely prevent the sides of the clip from moving any closer together after the removal of one or more cartridges from'the\ stack. When the clip is full with its double row of cartridges, the contracting pressure of its sides can only hold the stack snugly as a unit; but with less than a full stack, the pressureof the clip sides may tend to throw the depleted rows out of their proper alignment (viz, a tendency toward making one row out of the two rows) and thus disturb the proper feeding. For this reason, it is very desirable, with a pressure clip of th1s character holding a Vdouble row, to prevent the clip sides fromrcontracting beyond their normal position with a full stack, during the feeding operation while in the gun.

The modified form of clip shown in Fig. 8

Ais in alll respects similar to that heretofore tridge. In this embodiment, said lubricating means are constituted by depressed pockets 152b and 153b which serve to hold a thick lubricant such as cosinoline. If desirable, an oiled Wick may be secured in said pockets, the object in either case being to dab a small poition of lubricant upon each cartridge as it travels past said pockets in the loading operation. It is an advantage to have well lubricated cartridges for use in automatic guns and by the means described this lubrication is effected in a simple and effective manner.

From tlieforegoing description, it will be -I appreciated that an eiiicient and inexpensive clip is provided which will have the advantage of expendibility and light weight possessed by the stripping type of clip as well as the advantage of being both a holder and guide possessed by the detachable magazine box heretofore commonly employed in auto-- matic guns. It will be understood that the invention is not to be confined to the preferred embodiment thereof herein described and shown but that various changes may be made therein without departing from the scope and spirit of the invention as claimed.
