Patented Aug. 24, 1937 RECOIL PAD FOR GUNS Frank Pachmayr, Los Angeles, Calif., assignor, by mesne assignments, to Fray-Mershon, Inc., Los Angeles, Calif., a corporation of California Application January 28, 1935, Serial No. 3,777

9 Claims.

This invenion relates to and has for an object the provision of a substantially resilient cushion, or pad for attachment to the end of a gun stock and adapted to rest against the shoulder of a marksman for cushioning the body of the marksman against the impact resulting from firing a gun.

My invention contemplates the provision of an elongated body formed of soft rubber I mounted upon a base of hard rubber or other material, the body being formed with solid end portions of substantial thickness and the intermediate portion of the body being of cellular form with a plurality of tubular ribs extending transversely and open throughout their length and connected at their end to the outer and inner walls of the body by means of short ribs. Said tubular ribs are also connected by ribs extending therebetween and are of elliptical cross section with their major axes disposed at right angles to the outer and inner walls of the body, thereby providing between said tubular ribs, said walls and said ribs, inner and outer rows of cells which latter, as well as the tubular ribs, are col- Thus, the tubular ribs are readily collapsible when pressure is applied to the upper wall of the body, as when a gun is fired, thereby absorbing the shock resulting from the explosion, and are yet of sufiicient rigidity to withstand U the normal pressure of the gun against the body of a marksman without collapsing to an appreci able extent.

Another object is to provide a recoil pad for guns having a ribbed outer surface formed on the soft rubber body whereby the pad may be held against slippage against the shoulder of a marksman.

A still further object is to provide a gun pad formed with a cellular body of soft rubber superposed upon and secured to a sheet of rubber of the "same or harder quality and preferably of a distinguishing color, and a base of hard rubber or other material underlying the sheet of rubber for stiffening the body against bending at points intermediate its ends.

Other objects may appear as the description progresses.

I have shown a preferred form of my invention in the accompanying drawing, subject to modification within the scope of the appended claims without departing from the spirit of my invention.

In said drawing:

Fig. 1 is an external side view of my recoil pad attached to the end of a gun stock for use;

Fig. 2 is a top plan view of the pad;

Fig. 3 is a sectional plan of the same on line 33 of Fig. 1;

Figs. 4 and 5 are, respectively, transverse sections of the pad on lines 4-4 and 55 of Fig. 1.

In its preferred form the pad is formed with an elongated soft rubber body I having solid ends 2 and 3 and intermediate cellular portions formed with thin outer and

inner walls

4 and 5, a longitudinally arranged series of alined tubular partitions i2, 5, etc. of elliptical cross section, short ribs or webs l, 1, etc. connecting the outer portions of the partitions 6 with the outer wall d, similar ribs or

webs

8, 8, etc. connecting the inner portions of said partitions with the inner wall 5, and short ribs or

webs

9, 9, etc. arranged between and connecting adjacent portions of the partitions, as shown in Fig. 1.

A flat thin sheet it] of rubber or" a grade and color different from the body I is vulcanized to the inner wall 5, and a base of stiff hard rubber H is vulcanized to the lower sides of the sheet Ill, so as to form a composite pad incapable of bending longitudinally but capable of depression and collapse at points intermediate the solid end portions 2 and 3.

The outer surface of the pad is suitably ribbed, as shown in Fig. 2, at I2, either longitudinally or transversely, or otherwise, for providing a gripping surface for contact with the shoulder of a marksman and thereby preventing slippage of the gun and consequent inaccuracy in shooting.

At opposite ends of the series of tubular partitions 6 I provide arcuate cells l3, 13 which conform to the curvature of the adjacent portions of the endmost partitions 6, E and permit the outward distension of said endmost partitions. The form of the partitions 6 and the

ribs

1', 8 and 9 provide inner and outer rows of cells l4, l4, etc. which extend between the tubular ribs and the inner and outer walls of the pad.

The form and arrangement of the partitions, ribs and cells. is most important for the reason that sufiicient yieldability at local points is desirable in a pad of the character shown and described, without unnecessary distortion or general collapse of the body I. Yet the pad must be sufficiently stifi and unyielding as to permit the firm adjustment of a gun to the body of a marksman. Moreover, the elliptical form of the partitions 8, connected as they are with the outer and inner walls of the body and with each other, permit a more ready collapse and distortion of the partitions than is possible with circular or other forms of partitions, for the reason that when pressure is applied to the outer wall 4 the partitions 6 flatten out and incline themselves at angles of 45 degrees or less, depending upon the 5 amount of pressure applied, and nest snugly together at such angles. The end cells l3 contribute to the aforesaid result by approaching a semi-circular cross sectional form so that the walls of the adjacent partitions 6 may spread 10 laterally into the concavities of said cells l3.

When pressure is applied at points on the outer wall of the pad opposite the endmost partitions 6 the partitions at the two ends will incline in opposite directions, while the application of pressure at an intermediate point will cause the inclination of the partitions in either one or the other direction according to the extent and directness or indirectness of the line of pressure.

It will be understood that by extending the partitions 6 and the

ribs

1, 8 and 9 entirely through the body I without intersecting partitions or ribs, the pad is rendered uniformly yieldable and resilient throughout the cellular area, whereas such partitions or ribs would tend to stiffen the pad at the points of intersection. Obviously, the solid end portions 2 and 3 while yieldable because of the inherent resiliency of the material of which the body is formed, are substantially less yieldable than the intermediate portions of the pad.

The provision of the sheet ll) between the body I and base II, when formed of less yieldable material than the body I and of a different color and grade, serves as a bond between the body and the base and lends distinction to the pad.

As shown in Figs. 2 and 3, apertures l5, l5, may be formed in the body I, sheet 2 and base 3, for the insertion of screws by means of which the pad is detachably held on the end of a gun stock G.

As shown in Figs. 1 and 3, I may provide a series of posts IE, IS, etc. in a row intermediate the sides of the pad and connecting the

walls

4 and 5 with the horizontal ribs 9, for stiffening the pad in the center.

The ribs l2 are preferably of saw tooth form so as to provide firm grips and may be longitudinal or transverse, or both as shown.

It should be noted that the tubular members 6 are in line and equi-distantly spaced from one another and from the inner and outer walls of the pad. The cells or openings l3 of the inner row are directly opposite the corresponding cells or openings E3 of the outer rows, said cells being between said tubular members. Thus, the tubular members 6 are located centrally of the walls i and 5 are therefore free to collapse, with the walls thereof extended against the outer and

inner walls

4 and 5, such extension of the walls of said tubular members being made possible by the rows of cells I3. This arrangement provides the desired rigidity while, at the same time, permitting of a ready and positive shock absorber action.

Thus, the body of the pad may be said to be characterized by three vertical rows of transversely extending and spaced openings which define the central row of independently collapsible tubular members, the outermost rows permitting distention of the walls of said members when the same are collapsed.

1. In a recoil pad for gun stocks, an elongated "7 5 body formed of soft rubber and having solid end portions, a cellular portion between said end portions, inner and outer walls, said cellular portion including spaced and independently collapsible tubular members arranged between and spaced from said inner and outer walls and said end portions, and web portions joining said tubular members with one another and with said inner and outer walls.
