1 Claim. l

A still further object of the invention is to provide a locking means with a detent device which may be forced over an associated camming surface from either the fully open or fully closed position, said detent device having suflicient restraining force to hold the butt stock in either of said positions under normal use.

Another object of the invention is to provide the butt stock with a butt plate or shoulder rest which is normally resiliently held in a position perpendicular to the plane of said stock when the stock is in open position, which butt plate is capable of being folded into a plane parallel with the plane of said stock when the stock is in folded position so that the butt plate lies substantially flush against the barrel retainer of the Carbine.

A still further object of the invention is to provide acarbine having a folding butt stock associated therewith, said stock including a pivotal butt plate, or shoulder rest which is normally held in a position perpendicular to the plane of said stock when the stock is in open position by means of a spring, said butt plate being foldable into a plane parallel to the plane of the butt stock against the action of said spring when said stock is in folded position.

Another object of the invention is to provide a Carbine with a folding butt stock having a, pivotally mounted butt plate associated therewith, said butt plane being self adjusting in nature for fitting against the shoulder of the marksman, regardless of the position of the Carbine barrel, said butt plate being resiliently tensioned toward a position perpendicular to the plane of said stock when the stock is in open position and being foldable when the stock is in folded position into a plane parallel therewith whereby the butt plate lies substantially flush against the fore stock of the Carbine.

A further object of the invention is to provide a-re arm which may be used as a pistol or a rifle by the use of a folding butt stock which when in the folded position, permits the fire arm to be used as a pistol and which when in the extended position permits use of the re arm as a rie.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.

Fig. 12 is a View on the line lZ-IZ of Fig. 3 showing the butt stock in fully closed position, and;

Fig. 13 is a view in section taken on line l I-I l of Fig, 10, showing the butt stock in the semiclosed position as indicated in dotted lines in Fig. 10.

This invention is directed to an improved Construction for carbines whereby the Carbine may be utilized as a regulation gun or may be used in a manner of a side-arm through the use of a folding butt stock.

In order to accomplish a compact construction for a Carbine which adapts it for use as a sidearm, I propose to make the butt stoel: portion thereof foldable and to reduce the weight of said aliojeei A clip of bullets is shown at 32 and 34 inhingedly mounted to the fore stock at 36 and to the pistol grip 34 at 38 by means of a bolt 48. A spring detent device t2, to be described in detail hereinafter, holds the stock in either the open or the closed position.

A pivotally mounted butt plate or shoulder rest 'f--i is provided for the butt stock and is associated at the end thereof by a hinged construction by means of a spring 45. A cheek pad 48 is used both as a cheek rest and as a reenforcing lmeans for the butt stock 22 which is preferably made from tubing, and is disposed intermediate the ends of the stool; and is preferably of sheet metal construction having a cover of leather thereon.

The butt stock 22 consists of two tubular members 58 and 52. The member 5) includes a hinge member 54 at the Carbine end thereof which is hinged to the bolt 43. The hinge member 54 is preferably formed from brass or Some other suitable material and is brazed or otherwise attached to the tubular member 55 by means of a reduced diameter portion thereof which fits inside the tubular portion 55. The other end of the tubular member i? is bent and notched as at 56, to receive one end of the spring 45. rIhe notched portion 56 of the tubular member 5) passes through a journal 5S in the butt plate or shoulder rest.

,The tubular member 52 also includes a hinge member 6 at the'carbine end thereof which hinge is attached in a manner similar to that already discussed in connection with hinge member 54. Hinge member GS differs from hinge member 54 in that a camming projection 62 is provided thereon which has a function in connection with the locking device to be described hereinafter. The opposite end of the tubular member 52 is bent substantially at right angles to the main portion thereof and is carried by a journal S4 on the butt plate 44. The end of the tubular member '52 is notched as at Sii similar to the notch in member 5 which notch 5t receives the other end of the spring 4t. The spring 46 is of a special type wherein two coil portions are wound in opposite directions and are spaced from one another by an interconnecting portion 63. The portion 8B, when the butt plate is assembled to the stock 22, rests against an abutment 'l0 on the butt plate and normally the spring is so tensioned by the action of portion 68 againstrthe abutment 'l that the butt plate is held in a position substantially perpendicular to the plane of the butt stock when said stock is in open position. However, when said stock is in closed position, and the locking device 42 acts to hold said stock in this position, the butt plate is pivoted about its journals 58 and 64 into a plane parallel to the plane of the butt stock. This action is shown in Fig. 4. In this position it is apparent that the locking device overcomes the tension of spring 46. When the butt stock is again open the butt plate pivots through the action of spring 46 into its normal position perpendicular to the plane of the butt stool-x.y n abutment 'Il may also be provided for positioning the ends of the members 50 and 52.

Referring particularly to the locking device 42, as shown in Figs. l0 through 13, it will be noted that the pistol grip 34 of the Carbine includes a downwardly extending positioning portion 'I2 over which isfitted a metal cup i4 of the locking device; The portion l2 prevents the cup 14 from turning relative to the grip, a screw may be used to hold the cup 74 to the butt portion 12 if desired. Cup I4 is cut away at lt to permit the hinge member 60 to pass therethrough. In the bottom of cup 14 is an aperture 13 which is of non-regular contour. Into this aperture is fitted a threaded detent 88 which includes a camming surface 82 complementary to the cam 62 which fits therein. in either one of two positions, namely, fully open. or fully closed position of the gun stock. The boltv 40 threads into the detent 8i) and draws the cup- 14 tightly against the grip 34. Since the cup '141 is non-rotatable with respect to the grip and since. the detent 80 passes through a non-regular aperture therein it is apparent that the detent 80 is'y also non-rotatable. A strap holder 84 may also1 be positioned between the cup 'I4 and the head of,` the detent 85 and held to the gun through action. of bolt 40.

In order that the camming surfaces are engaged with one another I provide the pistol grip 'member 63 thereby urging the hinge member E;

away from the bottom of the grip. In this manner when the hinge member B0 is in the position shown in full lines in Fig. 10, the spring 88 presses the same downwardly so that the cam 62 engages. into the complementary camming surface 82 of detent thereby locking the butt stock in open position. When it is desired to fold the stock intoclosed position pressure is applied thereto to pivot, the same around the grip 34. When the pressure overcomes the spring 88 the cam 62 rides over the camming surface 82 in detent 80 due to angling of the walls thereof and is then in position shown in Fig. 13 and in dotted lines in Fig. 10. After the butt stock is pivoted at so that it lies substantially flush against the fore stock 25 of the Carbine the cam 52 is again in position to engage the camming surface 82 of the detent 80 and the spring 88 causes a locking action to occur whereby the butt stock 22 is locked in closed position or folded position. Obviously when itY is desired to unfold the butt stock a reversal of the series of operations described heretofore occurs and the cam 62 rides out of the camming surface until the butt stock has been rotated substantially 180 whereupon the cam again locks said stock in po.V

sition through the detent 8i)V of the locking device 22. .Y

The cheek rest 48 is formed from several portions of sheet metal, as shown in Fig. 9, andpreferably after the tubular members 50 and 52 are clamped therebetween, is spot welded or riveted together to hold these tubular members in posi-V tion, All of the sheet metal work is turned so as to provide smooth surfaces at one side thereof so that the vmember may be used as a cheek rest. This will be noted in Fig. 9. Y

From the foregoing it is apparent that I have provided a folding butt stock for carbines which is easily manipulated from open to closed position and which includes a pivotally mounted butt plate or shoulder pad and a highly effective though simple` locking device for the stock. The

overall weight of the carbine is reduced by the stock since the stock is preferably made from tubing and light Weight although of high strength, thereby presenting a `carbine which may be carried as a side-arm due to its light weight Aand short length.

While theembodirnent of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claim which follows.

What is claimed is as follows:

A carbine comprising in combination; a fore stock, a pistol grip, a butt stock foldable through a hinged connection about a vertical axis of said pistol grip to a position contiguous with the side oirsaid stock, ardetent device associated withsaid butt stock and said pistol .grip and eifective when said butt stock is in fully extended and fully folded positions to effectively lock said stock in either of said positions, said detent including resilient means which may be overcome by pressure On said stock whereby the stock can be changed from one of said extreme positions to the other, a butt plate pivotally attached to said butt stock, and a second resilient means for holding said plate in a position perpendicular to the plane of k FREDERICK W.
