I RANK D. HAWKINS, 01? SIOUX FALLS, SOUTH DAKOTA.

I RECOIL PAD.

Application filed November 10, 1924. Serial No. 748,954.

To all whom it may concern.

Be it known that I, FRANK D. HAWKINS, a citizen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements 1n Recoil Pads, of which the following is a specification.

This invention relates to certain new and useful improvements in recoil pads and pertains more particularly to an improvement on my Patent No. 1,325,152 of December 16, 1919.

The primary object of the invention is to provide a pad wherein the longitudinal central portion has a relatively rigid support that affords a line of flexure common to and for the opposed side portions, which latter beyond such line are consequently relatively resilient and are free to flex about the line to take up shocks.

A further object of the invention is to provide a support which strengthens and formation of the pad.

stifi'ens the cellular and which afi'ords effective anchorages for the attaching screws, or other similar fastening means. I

The invention further aims to provide means of the nature set forth, which closes the cells at their central portions against the passage of air therethrough, and which divides the cells into two separate and distinct divisions.

In the drawings Fig. 1 is a side elevation of the rear end of a gun stock with the present invention applied thereto. FFig. 2 is a view taken on line,22 of Figs. 3 and 4 are sectional views taken on lines 33 and 44 respectively of F i 1.

In proceeding in accordance wit the present invention, the pad isformed of two similar sections, each of which is made of soft rubber and has an inner wall 1, an outer wall 2 and solid -end parts 3. The parts of .the sections intermediate the ends 3 are connected by webs 7 of zig-za formation to provide a cellular or truss ormation.

longitudinal soft rubber strip 4 is interposed between the inner sides of the sections and is connected thereto, for example by cementing. -A rubber sheet 10 is cementthe adjacent 4 and a simied to the inner wall 1 and to longitudinal edge of the strip lar although thicker rubber sheet 9 which forms a face plate that rests against theshoulder of the gunner, is cemented to the outer wall 2 and to the adjacent longitudinal edge of the strip 4. v 1 The sheet 10 is cemented to a hard rubber base plate 8. The cells are thus closed against the passage of air therethrough and each receives support at its inner end from the strip 4. The strip 4 acts as a stifi'ener which extends centrally of the width of the pad, and which acts to prevent ready flexure of the outer sides of the cells and plate.

The strip 4 is furthermore formed with perforated enlargements 5 to enable the passage therethrough of fastenin screws 6 or the like, the latter extending ti tering perforations in the hard rubber base plate 8 and securing the entire device onto the gun stock.

The strip 4 further acts to strengthen the truss or cellular. formation and to revent same from-breaking down through lbng or constant use. J

What is claimed is 1. In a rubber recoil pad for gun stocks, a pair of sections each having spaced inner walls, solid end parts connecting the walls, cellular connections between the walls, "a central soft rubber strip interposed between the inner sides of the sections and v engaged therewith, and inner and outer rublongitudinal edges of the central st'rip.

In a rubber recoil pad for gun stocks, spaced inner and outer walls, cellular connections between the walls, and a rubber strip extending longitudinally of the walls and central of the provide a stiffening means resisting flexure of the parts of thecells adjacent the strip while permitting flexure of the remaining parts of the cells.

In a rubber recoil her body, and a longitudinal rubber stri in the body disposed central of the width thereofto resist flexure of the inner parts of the cells and to allow of flexure of the outer parts thereof and to close the cells 105 against the passage of air therethrough.

4. In a recoil pad for her body having spaced inner and outer walls,

means to flexibly connect the walls,

and means disposed longitudinally of the no rough regiswidth thereof so as to .95

pad, a cellular rubgun stocks, a rubwalls and central of the width thereof for resisting fie adjacent to said second means while permitp ting fiexure gitudinally of the xure of the connecting means arts of the cells wh of the outer parts ther passage of the remainder of the confor gun stocks, a cellubody and between the sides thereof to resist flexure of the inner ile permitting fiexure eof and to prevent the of air through the cells. In testimony whereof I afiix my si nature FRANK D. HAWKINS.
