15 Claims.

This invention relates to improvements in firearms and more particularly to an improved form of combined stock and forearm extension, and means to connect them together in aligned position along the barrel of the firearm.

It is often desired that the forearm portion of a firearm stock be extended beyond its usual termination to a point closely adjacent to the muzale end of the barrel of the firearm. This would necessitate the procuring of a substantially long piece of wood of the proper grade for such use, which has been found to be bothimpractical and quite expensive. To properly form such a long piece of wood, it was also necessary to either purchase additional machinery or to remodel the present ones, and in view of the relatively small production required, this was also undesirable.

To obviate the above disadvantages and yet provide a firearm stock with an extended forearm portion, it has been proposed to make the stock portion of one piece of wood and the firearm portion extension piece of another, and abutting their adjoining ends; This was undesirable in that it was particularly diflicult to obtain two pieces of wood which would desirably match in respect to color and graining, and also that the jointure at the abutting ends was dimcult to make and maintain tight and of neat appearance, due to the expansion and contraction of the wood under varying atmospheric conditions and the shock of recoil from firing the firearm.

Another proposal was to dispose the joint, between stock and forearm portions, at the jointure between th receiver and the barrel of the firearm and securing the opposing ends of the, respective portions to the receiver by means of a band adapted to encircle these opposing ends and a screwthreaded end of the receiver, and to screw-thread this band thereon. This form was both expensive to make and to assemble, and also interrupted the smooth stream-line appearance of the combined receiver and barrel. In some instances such a form tended to interfere with the proper sighting of the firearm, due to such interruption of the smooth appearance distracting the attention of the user of the firearm during the sighting operation, or of distorting the sighting due to light reflection from the raised band portion.

In order to obtain the advantages of an extended forearm, and to meet the demand for firearms provided with the same, without the above disadvantages being present, it is proposed, as one object of this invention, to provide an improved firearm having a combined stock and forearm portion and a forearm extension, which are connected together by a U-shaped band, which band does not encircle the barrel to interrupt its continuous appearance, and is wideenough to sumciently interrupt the continuity of the wood from which these parts are made, so that differences in color and graining, between the connected parts, are substantially unnoticeable.

Another object is to provide in a firearm a combined stock and forearm extension of the above nature, the opposing ends of which are slightly spaced apart, and means to cover the spaced apart ends of .these parts While securely connecting them together. 7

Still another object of this invention is to provide means to connect separated aligned stock and forearm extension portions together and which is of such form that the surface continuity of the assembled parts is not interrupted.

A further object is to provide in a firearm, stock and forearm extension connecting means, a sling strap loop for the firearm, and common means to secure the sling strap loop and the connecting means to these parts.

A still further object of this invention is to provide an improved form of firearm which will be relatively inexpensive to manufacture, simple in construction, pleasing in appearance, and which is very efficient and durable in use.

, With these and other objects in view, which will appear as the description proceeds, there has been illustrated in the accompanying drawing, two forms in which the invention may be conveniently embodied in practice.

In the drawing, wherein like reference numerals designate like parts throughout the several views:

Figure 1 is a side view of a firearm embodying the features and principles of this invention;

Figure 2 is a broken enlarged sectional view of the front end of the firearm shown in Figure 1;

Figure 3 isan enlarged cross-sectional view taken on the line 3 3 of Figure 2;

Figure 4 is an enlarged exploded View of the opposing ends of a combined stock and forearm portion, a forearm extension portion, and a novel connecting means therefor;

Figure 5 is an enlarged broken top plan View of the jointure betwene the stock and forearm extension portions, and the connecting means therefor;

Figure 6 is a cross-sectional view similar to Figure 3 of a modified form of the invention j Figure 7 is a bottom view of the jointure between the stock and the forearm extension portions of the form shown in Figure 6; and

Figure 8 is a broken sectional view showing the means for securing the forearm extension to the firearm barrel, when a tubular magazine is not provided.

Referring now to the drawing, and particularly to Figures 1 and 2, the numerals II and I2 denote the stock and forearm portions respectively of a combined stock and forearm formed of one piece of wood and which for purposes of descriptive brevity will be hereinafter termed a gun stock. In this instance, the forearm portion l2 of the gun stock is extended toward the muzzle end 13 of a barrel l4 and by means of aso-called take-down screw I5, which screw threads into a post It extending downwardly from the receiver I! from which the barrel l'4 extends, the gun stock is firmly secured to the receiver ii and the barrel 14. In this instance, suitable sights l8, secured to the receiver l1, l9 secured to the rear end of the barrel l4, and 2|, secured at the muzzle end of the barrel, are provided. The firearm shown is" of bolt action type, and has a bolt 22, a bolt operating handle 23, a trigger 24', and a' trigger guard 25, as well as a tubular magazine 26 which, in this instance, extends along beneath the barrel l4 and is hung from and secured. thereto by a ring 21 having a threaded stud 28 which is screw-threaded. into the barrel l4.

In accordance with the features, objects, and principles of this invention, a forearm extension 31 isprovided which extends from the forward end 32 of the forearm portion l2 of the gun stock to a point closely adjacent the muzzle end of the barrel Hi. When the forearm extension 3| is reasonably long, its forward end may be se cured to the magazine retaining ring 21 by means of a screw 33 which is screw-threaded into the ring 21, see Figure 2. The opposing ends 32- and 34, of the gun stock and the forearm extension 3l respectively, are slightly spaced apart to obviate the necessity of accurate fitting and to allow for any elongation of either, lengthwise, due to atmospheric conditions. Both the forearm portion 12 of the gun stock and the forearm extension 3|, in this instance, are provided with a longitudinally extending" groove 35 in their upper surface, to receive the tubular magazine 26 and to form a seat 36- for the barrel [4.

The sides of these stock and forearm parts extends upwardly about the barrel l4 at either side thereof to substantially its axis, and axially along the barrel substantially parallel with its axis. In the form shown in Figure 8 no tubular magazine is provided and hence no groove to receive the same is provided. The upper surface of the gun stock and forearm extension, however, is grooved out to provide a seat 31 for the barrel 38. In this form the forearm extension 39 may be secured directly to the barrel 38 by a screw 4| passing through the extension 39 and being screw-threaded into the barrel 38.

A band 42, generally U-shaped in cross-section, and preferably made of sheet spring steel, is provided to cover the spaced apart ends 32 and 34 of the gun stock and the forearm extension 3! respectively and to connect them together. The band 42 has its upper edges 43 and 44 spaced apart to permit the barrel M to pass therebetween a suflicient amount to seat upon the gun stock and forearm extension 3| upon the seat 36 provided therefor. The edges 43 and 44 are each inturned toward the barrel l4 and are in engagement with the same on either side thereof, and lie upon the upper edge of the gun stock and forearm extension 3! at either side thereof.

In this instance, and to insure that the outer surface of the band 42 is flush with the outer surface of both the gun stock and the forearm extension 3!, outer peripheral surfaces of the opposing ends of these parts are cut away so that the band 42 is set into the same with its end edges 45 and 46 abutting shoulders 41 and 48 respectively formed at the ends of the gun stock and the forearm extension 3|. Preferably the length of the band 42 is somewhat greater than its height so that it will extend over each of the opposing ends 32 and 34 sufficiently to firmly support the forearm extension 3! in connection with the gun stock without it sagging out of alignment therewith. The band is also spring tensioned. to urge its sides 49 and 5| toward each other whereby these sides will firmly grip against the: side portions of the gun stock and the forearm extension 3! disposed therebetween.

In addition to the connection between the band 42 andthe opposing ends 32 and 34 of the gun stock and the forearm extension 3! respectively, screws 52' and 53 may be provided which pass through openings provided therefor in the band 42 and screw into the undersurface of the gun stock end 32 and the forearm extension end 34 respectively. In Figures 1, 2, and 3 the screws 52 and 53 also secure the. base plate 54 of a sling strap loop 55 which, in this instance, is pivotally and detachably connected tothe base plate 54 by a cylindrical stud 56 having a cross tongue 5'! on its outer end adapted to pass through a slot (not shown) but formed in the base late 54 to allow'the tongue to pass therethrough and be rotated to lock the loop 55 to the base plate. A leaf spring 58, is provided to releasably lock the tongue in place. A detaildescription of the form of'sling strap p shown herein will be found in Patent No.- 2,102,964 issued December 21, 1937, to.

OscarF. Mossberg.

In the form shown in Figures 6 and '7, the strap loop is secured directly to the band 6! by having its tongue 5? passed through a longitudinally directed' slot 62 provided in the band 61 and then rotated to lock it to the band 3 I, the leaf spring 58 snapping into the slot 62 to releasably lock the tongue in its rotated position.

By the provision of a band 42 of the form shown and'described, which connects the gun stock and forearm extension 3 i together, no interruption in the smooth streamlined surface of the barrel l4, ispresent, the connected gun stock and forearm extension are rigidly held in alignment, and their surfaces are spaced apart sufficiently so that differences in the color and graining of these parts is substantially unnoticeable. The shape of the band 42 whereby the forearm extension is firmly supported upon the end of the gun stock without sagging out Of alignment therewith is particularly useful and novel, and forms a simple and inexpensive means into which the opposing ends of the gun stock and forearm may be telescopically inserted, and by which they are rigidly supported and connected. r

While there have been shown and described herein, two forms of an improved firearm, itis to be understood that the features and principles of this invention may be embodied in, other forms without departing from the spirit and essential attributes thereof. It is thereforedesired that the present embodiments be considered in all respects as illustrative and not restrictive, and it will be further understood that each and every novel feature and combination thereof, present in, or possessed by, the improved firearm herein disclosed forms a part of the invention included in this application. i
