7 Claims.

This invention relates to firearms having short stocks or pistol grip butts, in combination with a light Wire folding stock for extension to shoulder rest firing. Objects of the invention include the provision of a light weight, short firearm having a folding stock, such firearm being particularly adapted to the needs and uses of parachute troops, tank. motorcycle, and other mechanized troops, police riot squads, and other persons needing an effective weapon of light weight, easy manipulation, and smallsize but of greater effect and accuracy than the usual hand gun.

Other objects of the invention include the provision of a sturdy, folding, light gun which can stand great abuse in warfare without becoming disabled, and to this end the invention comprises a special pistol grip and unitary long forearm forming the stock, a short barrel on the forearm, and a sturdy folding wire frame shoulder stock r butt, said wire frame being especially constructed for rigidity in use, ease of operation, and small liability of breakage even when thrown about as in parachute landings and fighting, combined with small size and light weight for great convenience.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a view in side elevation of a firearm according to the invention and showing the shoulder stock in folded condition;

Fig, 2 is a view similar to Fig. 1 but with parts broken away and showing the shoulder stock. in

extended condition;

Fig. 3 is a rear view of the pistol grip looking in the direction of arrow 3 in Fig. 1;

Fig. 4 is a section on line 4-4 of Fig. 1;

Fig. 5 is a plan view of the shoulder stock bearing and catch plate;

Fig. 6 is a section on line 6-6 of Fig. 5;

Fig. 7 is a plan view of the cover plate for the bearing and catch plate; and

Fig. 8 is a section on line 88 of Fig. 1.

In Fig. 1, the numeral l0 indicates a barrel having a receiver l2 for mechanism providing for semi or full automatic fire of shells housed in a magazine l4, depending from a magazine guide l6 and being quickly detachable therefrom for'inbe made of wood or similar material and depending from its rear end it is provided with a unitary pistol grip 20. Means not shown may be used to secure the parts together, and as so far described the firearm may be used as a hand gun by grasping the pistol grip in the gun hand, or it may be used as a two-hand gun, for instance in firing from hip or waist level, by grasping the grip 29 in the gun hand and using the depending 7 magazine I4 as a fore grip in the other hand. Sling swivels 22 may be used for a sling and to strap the weapon to the thigh for ease in carrying, as for instance by parachute troops, motorcycle troops, police, etc. It is preferred to make the overall length of the weapon as so far described about twenty-two inches for easy carrying on the thigh or elsewhere, but this length is not necessary and, may be varied without de arting from the scope of the invention.

A plate 24 having a transverse lug 26 in the plane of the plate is imbedded in the stock so that its outer surface coincides with the surface of the stock. as shown in Fig. 4. A pair of strong spring ears 28 extend outwardly from plate 24, these ears having their free ends bent slightly toward each other, Fig. 6, and they are provided with depressions 30 for a purpose to be described. A pair of spaced fastener receiving apertures 32 extend through plate 24.

A cover plate 34 corresponding largely in shape to plate 24 overlies the latter and is secured to the stock by fasteners 36 extending therethrough and through apertures 32 in plate 24, Plate 34 is provided with a transverse generally semi-cylindrical depression 38 intermediate its ends, and as shown in Fig. 4, this depression, together with the adjoining part of plate 24, forms a journal for a wire 40, the latter being part of an open Wire shoulder stock or butt 42 which clearly is pivotable from Fig. 1 to .Fig. 2 positions to be folded against the forearm 18 or to extend rearwardly for use as a shoulder stock. Plate 24 takes most of the Wear of the pivoting action and ensures against loosening of the wire stock. The inwardly turned ends of ears 28 act to guide the runs 44, 46 onto the ears, and depressions 30 snap-lock these runs rigidly in extended position of the wire stock. The lug 26 acts as a stop and bearing plate for the wire frame run 44 in extended position of the wire stock so as not to wear the forearm and consequently lose the rigidity of the stock after use. Also, by the two plate construction, the wire 40 is enabled to pivot right at the surface level of the forearm l8, and ears 26 hold the wire stock at this the rear end of the receiver. This forearm may level, so that the stock is enabled to lie just about in contact with the forearm and pistol grip and as close thereto as possible for easier and more accurate manipulation of the gun.

It is to be noted that plates 24, 34 are set at an angle to the barrel so that the wire stock will, when extended, also lie at an angle to the barrel in the natural position for a shoulder resti stock. However, when folded, the run 44 would extend above the barrel and might interfere with effective use of the weapon if operated in folded condition. To locate the wire stock as shown in Fig. 1, a catch plate 48 is sunk into the forearm as shown in Fig. 8, and an car 50 integral with the catch plate is located at an angle to the shoulder member 52 of the wire stock. Hence the latter cannot be secured by catch ear 50 without depressing the entire wire stock in the 4. A firearm as recited in claim 1 wherein said first named plate lies substantially flush with the surface of the forearm, and including a lateral extension on said first named plate against which the folding shoulder stock may be stopped in its extended condition.

5. In a firearm of the class described, a barrel, a forearm supporting the barrel substantially throughout the length of the barrel, a pistol grip at one end of the forearm, and a folding shoulder stock mounted on said forearm, said stock having a wire portion acting as a pintle, a pair of superimposed plates on said forearm, means forming an outwardly extending recess in one direction of arrow A in Fig. l, and the lower edge of ear 50 will then hold the stock as shown, providing a corner 54 for conveniently hanging the Weapon on a hook or rack.

It will be seen from the above that I have provided a light, easily manipulatable weapon having a light, but sturdy and convenient shoulder stock, the gun being usable as a shoulder or hand gun and being easily carried and stored in tanks, planes, cycles, etc.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. A firearm comprising a forearm having a pistol grip, a folding shoulder stock, means mounting the folding shoulder stock on said forearm, said means comprising a, plate in said forearm, a "pair of spring ears extending outwardly of the forearm, a second plate overlying the first named plate, a depression in the second plate forming a journal with a portion of the first named plate, a portion of said shoulder stock being pivotally disposed in said journal, and other portions of said shoulder stock being adapted to be latched by said spring ears in extended condition of the shoulder stock.

2. A firearm as recited in claim 1 wherein said first named plate has its outer surface substantially flush with the surface of the forearm and said second plate has its inner surface substantially flush with said forearm surface.

3. A firearm as recited in claim 1 wherein said second plate lies between said ears in contacting relation therewith.

of "said plates, said pintle being journaled in said recess and in contact with the other plate, a pair of spring ears on one of said plates for latching the stock in shoulder-rest condition, and a spring catch for latching the stock in folded condition thereof.

6.- A firearm as recited in claim 5 including a lateral lug on. one of said :plates, said lug extending laterally beyond both plates and being located rearwardly of said pintle to act as a stop for the folding shoulder stock in extended condition thereof.

7. In a firearm of the class described, a short barrel and receiver, a forearm substantially the length of the barrel and receiver, a, pistol grip at one end of the forearm, a bent wire shoulder stock pivoted to the forearm to be swung between positions wherein the stock lies in folded condition against the forearm or selectively extends rearwardly beyond the pistol grip to form a shoulder rest, and means pivoting the stock to the forearm, said means comprising a pair of superimposed contacting plates one of which lies fiush with the surface of the forearm, said one plate having a pair of outstanding spaced spring ears, the other plate lying between the ears and forming a, lateral support therefor, a lateral stud in said one plate to act as a shoulder stock abutment, and an outwardly extending substantially semi-cylindrical depression in said other plate forming :a journal with the adjacent surface of said one plate, a portion of said shoulder stock entering said journal, and said stock having means adapted to be latched by said spring ears in one position of the stock.
