RECOIL-PAD FOR FIREARMS.

Specification of Letters Patent.

Patented Aug. 17, 1920.

Application filed Nov-ember 4, 1919. Serial No. 335.590.

To all'whom it may concern:

Be'it known that I, WEBSTER L. MARBLE, a citizen of the United States, residing at Gladstone, in the county of Delta and State 5 of Michi an, have invented certain new and useful Improvements in Recoil-Pads for Firearms, of which the following is a specification.

This invention has for itsfobjects, first, the provision of a rubber cushion or recoil pad for firearms which is of improved construction whereby, while readily responding to the recoil and serving as a check or shock absorber, it will have such stability that its walls will not flatten or collapse too suddenly at the instant of recoil; second, to provide a novel recoil pad comprising a rubber cushion or shock absorber and a pair of metal clenching plates, the whole being a self-contained device adapted for attachment as such to-the stock of the fire arm, or for removal therefrom, without necessitating the use of cement or the employment of two or more kinds of rubber cemented together; third,

to provide a novel rubber recoil pad of such form that it will have. extreme resiliency, without requiring the use of springs, so that it will adequately take up the recoil when the fire arm is discharged and yet-will not flatten or collapsc toosuddenly atthe instant of recoil, combined with a pair of improved metal clenching plates serving as a base by which the sad maybe readily attached as a unitarystructure-to the'stock' of a fire arm,

" or removed therefrom, either by the direct fastening of the device by: screws, or, by detachable connecting means'such as I have provided, for instance, in my application Serial No. 287,736,'fil'ed April 5, 1919.

40 In my invention, instead of using cement to attach the pad to the gun stock, or molding metal attaching frame in the rubber forming the cushion, or forming the pad with a ca'p'to fit over the stock, or employing 4 inflatable sacks or chambers, a'pair of plates is applied to the rubber cushion in an improved manner soas to form a unitary structure therewith which is self-contained and attachable as such to the stock .of the fire ,arm, either by directly screwing the plate to the stock, or,providing special attaching means for that purpose as proposed, for instance, in my application Serial No. 287,736. The rubber pad is formed for the applica- Thc rubvplate ber pad is of novel form, provided with ribs or bars whose edges are normallyispaced from the attaching plates, thereby obtaining the novel effect of stability, without the pos sibility of flattening or collapsing suddenly at the instant of recoil and giving the pad both pneumatic and cushion features, while permitting it to be constructed of a minimum amount of material having ample strength and durability. The spacing of the edges of the ribs from the plates permits the cushioning movement or compression to occur, with ready yielding of the ribs, and

yet the extent of compression is limited so that the pad will not suddenlylcollapse.

The clenching plates are formed and correlated in an improved manner, affording a rigid and stiff base for the pad and an adequate clenching action on the latter.

'The invention is susceptible of modification and the disclosure thereof is robe considered as illustrative, instead of restrictive, of the scope thereof,

In the accompanying drawings,

clenching plates of the form of the invention shown in Figs. 8, 9 and 10, before said plates have been clenched.

A portion of the stock of a fire arm is shown at 1. My present invention can be embodied in a'form adapted for attachment in a special manner, as shown in 1, for instance, by the useo f means such as set forth in my application Serial No. 287,736, thereby permitting quick and easy substitution ofa recoil pad of a given thickness for a pad of any other thickness, or, the pad may be directly screwed to the stock 1 as shown in Fig. 8.. 1V hichever manner of attachment is employed, the principle of the invention remains the same.

Referring first to Figs. 1 and 3, the special means for attachment of the pad comprises a butt plate 2 having a dove-tailed rib 3 and secured to the stock 1 by screws a. A spring 5 secured to the plate 2 at the point 6 is adapted to lock the recoil pad after it has been engaged with the rib 3. I

The attaching device just described is shown in my application Serial No. 287,7 36.

My present invention comprises three parts, a recoil pad 7 and inner and

outer clenching plates

8 and 9. The plate 8 is provided with slots 10 anl an elliptical flange 11 offset from the face of the plate. The plate 9 has a longitudinally extending dove-tailed channel 12 terminating in a flange or stop 13, and lateral flanges or beads 1 1 which are turned down at 15. The plate 9 is provided with struck up tongues 16 which are originally in the form shown in Fig. 6 and are passed through the slots 10 and clenched down as shown at 17 to clamp the

plates

8 and 9 together in engagement with the recoil pad 7 as shown in Figs 1 to 1. Another tongue 18 which is bent at right angles and extends through the center slot 10, serves as an abutment for the locking spring 5. The spring 5 is adapted to snap into the slot 10 when the pad is in position. To attach the recoil pad, in the before mentioned form of the invention, the channel 12 is made to receive the end of the rib 3 and the pad is then slid into position with the shoulder 3 abutting the flange or stop 13,

whereupon the spring 5 snaps into the'center slot 10.

This particular fastening means for a pad for a fire arm stock, I do not claim herein as the present invention is not limited to this manner of attaching the

clenching plates

8 and 9. and the pad 7, to the stock 1.

Referring to Fig. 5, the recoil pad 7 is of soft rubber, of a general outline adapting it to serve the purpose for which it is intended. Said pad is hollow and open at its inner face as shown at 19, said opening being flanked by grooves 20 which receive the turned down portion 15 of the flange 14:. The pad is also cut away at 21 to receive the end portion of the plate 9 and it is cut away at 22 to receive the opposite end of said plate below the stop 13. The plate 9 is provided with struck up clenching prongs 23 which penetrate the web at the cut out portion 22. These prongs may bear against the elliptical flange or bead 11 or stop short of it. i

r The hollow pad '7 is provided with a plurality of relatively thin parallel partitions, ribs or bars 2 1 whose free edges 25 are spaced from the plate 8, thus permitting the clenching plates to move a given distance before the plate 8 comes in engagement with said partitions or ribs. hen the fire arm is discharged the recoil causes the aforesaid relative movement, which absorbs the shock and when the partitions or ribs engage the plate 8, cushioning boxes are provided between the partsso that the effect is a combined cushion and pneumatic action. The space between the edges of the partitions and the plate 8 permits instant response at the time of discharge, the cushioning effect being thereafter more gradually exerted when the contact is effected. An opening 26 extending through the pad 7 is in line. with the spring 5 so that by the insertion of a nail, pencil, or other suitable device, the spring 5 may be depressed to permit the pad to be removed.

It will be observed that the

plates

8 and 9 have their clenching flanges or parts 11 and 14: disposed on opposite sides of the flange or part 27 of the pad 7, leaving the major portion of the pad 7 free to flex as before described. 7

Referring to the, form shown in Figs. 8 to 12, the form of the inner clenching plate 8 is the same as previously described, but there are three, instead of two, tongues 16 to clamp the

plates

8 and 9 together; also the plates have

openings

28 and 29 for the reception of screws 30 which are intended to pass into the stock 1 in, the screw holes occupied by the screws which hold the ordinary butt plate, the latter having first been removed. The special fastening means previously described for use in attaching the recoil pad to the stock, is not used in this form of the invention. Consequently, it is unnecessary to form they outer clenching plate 9 with a channel and stops. The outer plate 9 is of substantially the same appearance as the inner plate 8. The pad 7 is provided with openings 81 which are in line with the

openings

28 and 29.

The action of the pad in the construction shown in Figs. 8 to 12 is the same as previously described.

It will be observed that my improved pad comprises a soft rubber cushion and a pair of clenching plates which afford a base for securing it to the'stock and that the use of cement is entirely eliminated; furthermore,

it is unnecessary to provide any special means for connecting the recoil pad to the stock although such special means may be used if desired, as shown in the form of the invention disclosed in Figs. 1 to 7 What I claim is: V
