STANN'ARD AND Application led September The present invention relates to recoil pads for guns and is particularly concerned with improvements in the type of recoil pad having a. relatively hardbase plate Jfor attachment to a gun stock, and a relatively soft rubber cushion carried by the base plate for engagement with the shoulder of the mechanism. p Y

One of the most important objects of the invention is the provision of a recoil pad in which the resiliency or cushioning effect may be conveniently adapted to suit the needs of each individual marksman, preferably without changing the external appearance or other characteristics of the recoil pad.

Another object of the invention is the provision of recoil pads for guns havinga relatively stiff supporting member, a relatively soft shoulder engaging member, and an intermediate cushioning structure, the characteristics. of which may be varied at will to adapt the recoil pad to the individual feel of the marksman at any point of en-v gagement with his shoulder.

Another obj ect of the invention is the provision of a recoil pad of the class described which is provided with a plurality of intermediate cushioning devices of graduated length, adapted to comeinto operative engagement with other parts of the pad at Y different stages of distortion of the pad, to

produce a pad of predetermined characteristics. I v

Another object is theprovision of a recoil Vpad lia-ving a plurality of air pockets, the

air volume of which may be regulated to v change the characteristics of the recoil pad to suit the individual needs of' any marksman. `Another object is the provision of a recoil pad in which the resiliency may be controlled or predetermined by the combined ef-V feet of pneumatic pockets and other resilient devices adapted for successive operation at' different stages of distortion orp the pad.

Other objects and advantages of the invention will be apparent from the following description.-l and from the accompanying i drawings in which similar characters of reference indicate similar parts through the several vlews. l

Referring to Figures 1 to 5, 10 indicates a conventional gun stock which may be provided with a recoil pad, indicated in its entirety at 11, of a size adapted to substantially lit the end of the gun stock 10.

In the embodiments which have been chosen to illustrate the invention the recoil pad 11 preferably consists of a supporting member 12 of relatively stili lmaterial, a shoulder engaging member or cushion 13 and an intermediate cushioning device 14. However, it should be understoody that in some embodiments of the invention the supporting member, shoulder engaging member, and intermediate cushioning device'may 'all be constructed of an integral piece of material. l

In the preferred embodiment the supporting member 12'consists of a relatively still plate of hard rubber, the outer boundary 15 of which conforms substantially to the shape of the gun stock 10. The supporting plate 12 is provided with a plurality of counter.- sunk apertures 16 adapted to receive wood screws 17 forattaching the supporting plate 12 to the gun stock 10. The shoulder engaging portion 13 of the recoil pad 11 preferably consists of relatively soft rubber,the outer boundary 18 of the shoulder engaging member also conforming substantially to the shape of the end of the gun stock 10. The shoulder engaging member 13 is provided With a laterally curved or convex rear surface 19, giving the extreme edges 2O of the shoulder engaging member greater flexibility to prevent any possibility of undesirable rigidity at the rear corners of the pad.

rlhe intermediate cushioning device 14 preferably consists of a relatively flat body of resilient material, such as sponge rubber, having an outer surface 21 which also conforms substantially to the shape of the gun stock supporting plate 12 and shoulder engaging member 13.

There the gun stock 10 is provided With a. taper, the shape of the recoil pad 11 is preferably such that it forms a Continuation of the gun stock 10'along the same line of taper as shown in Figures 1 and 2. Thus the intermediate cushion 14 and the shoulder engaging member 13 are each slightly longer than the supporting plate 12, the lower outline 22 forming a continuation of the shape of the gun stock 10.

The intermediate cushioning member 14 is preferably provided With one or more air pockets 23, the air pockets 23 being closed at one end by the supporting plate 12 and at the other end by the shoulder engaging cushion 13. The supporting plate 12, intermediate cushion and shoulder engaging member may all be secured together by cementing, vulcanizing or other appropriate means and it Will thus be observedthat a plurality of air pockets 23 are provided from Which the air may escape only through the pores of the sponge rubber body 14. The foregoing structure provides a pad of great resiliency Which is adapted to resist the recoil more effectively due to the presence of the air pockets Which entrap air to be forced out through the pores of the rubber.

The air pockets 23 are preferably provided with a plurality of resilient bodies 24 whichY are capable of coming into engagement with the supporting plate 12 and shoulder enraging` member 13 at different stages in the deformation or distortion of the pad. The resilient bodies 24 may take many different forms, depending upon the size and shape of the air pockets 23, but in the embodiment shown in Figure 3 a plurality of cylindrical air pockets 23 are provided with substantially cylindrical rubber plugs 24, the rubber plugs being of slightly smaller diameter than the air pockets 23.

The rubber plugs 24 are preferably madev of different sizes in order to adapt the resiliency of the recoil pad to the individual needs of any marlrsman and in the present embodiment, which is to be regarded as eX- emplary, the upper and lower plugs or resilient bodies 24 are slightly shorter than the length of their air pockets 23. The next tvvo resilient bodies 25 and 26 may be made still shorter and the middle resilient body 27 may be the shortest of all, assuming` that it is desired to provide a pad having the greatest rgsiliency or give adjacent the resilient body 2 lt should, of course, be understood that if the individua-l marlsman prefers the feel of a recoil pad Which is stiffer at the center and Which is not resilientor soft at other points, this result can be readily accomplished byproviding resilient bodies of appropriate length at the points desired. In general the resiliency or softness of the pad is increased by providing shorter resilient bodies 24 at any'particular point and in some cases the resilient bodies may be omitted entirely from certain air pockets.

The operation of the recoil pad shown in Figures 1 to 5 is as follows: When the recoil pad is subjected to pressure between the shoulder of the marlrsman and the gun stock 10 on recoil of the gun, the pad is distorted from its usual shape and the major portion of the distortion takes place in the intermediate rubber cushion 14. The shoulder` engaging port-ion 13 of the pad is also capable of permitting some distortion but is preferably of sufficient stiffness to distribute the force of the recoil over a greater area of the cushion 14. As the shoulder engaging portion 13 is forced toward the supporting plate 12, the air entrapped in the air pockets 23 is forced out through the pores of the sponge rubber 14 at a very high velocity, the air tending to increase the resilient resistance of the cushion 14. As soon as the shoulder engaging portion -13 approaches a certain stage of distortion relative to the supporting plate 12, the longest resilient bodies-24 come into vengagement with the supporting plate 12 and shoulder engaging member 3 and tend to increase the resistance ofthe pad. At another subsequent stage of distortion of the pad the resilient bodies 25 and 26 may come into engagement with the Walls of their air pockets'and finally the shortest resilient body 27 may come into operative engagement with the Walls of its air pocket to increase the resistance of the pad.

lt Will thus be observed that the resilient bodies 24 and 27 are adapted-to provide a pad of predetermined characteristics capable of meeting the individual needs of any marksman and the resilient bodies come into operative engagement With the other parts of the pad at different stages in the distortion'of the pad, thereby regulatingl the resiliency at any predetermined point. lf the marksman Wishes to protect any particular point uponA his shoulder, such as a spot which tends to become sore, he may do so by diminishing the length or size of the rubber plugs 24 at that point in the pad, thereby making the pad softer at that point. It should be noted also that the resultingcharacteristics of the pad are due in part to the shapes of the respective resilient bodies and their air pockets, and the resilient bodies themselves diminish the volume of air in the air pocket.

In the embodiment shown in Figures 6 and the air pocket 23 is an elongated air pocket having rounded ends 28 and the pocket eX- tends across substantially the entire end of the gun stock. In this embodiment the resilient body 24 comprises a rubber body having an outline 29 substantially complementary to the shape of the air pocket 28. One side 29 of the resilient body 2lin Figures 6 and 7 may be flat, While the opposite side BO may be provided With a concave or convex surface, spaced somewhat from the shoulder engaging portion 1.3 of the pad.

In the form shown in Figure 6 the resilient body 24 is thicker at the middle, thereby increasing the-resistance of the pad at the center after the pad has been deformed a predetermined amount, that is, after the shoulder engaging portion 13 is compressed suiiiciently to engage the rubber body 24. If it is desired to malle the center of the recoil pad softer the rubber body or filler 24 may be cut down to the concave shape illustrated at 3l.

It Will thus be observed that I have invented an improved recoil pad including a resilient casing and one or more resilient bodies carried thereby, by means of Which the resilient characteristics of the pad may be regulated or predetermined at any point and adapted to suit the individual feel of the user. The present invention is of peculiar importance to marksmen Who find that some certain portion of the shoulder requires additional protection or greater softness of the pad and in general the present recoil pad is adapted to give a maximum of satisfactory results in every individual case.
