assignor to Schweizerische Industrie-Gesellschaft, Neuhausen am Rheinfall, Switzerland Application June 13, 1957, Serial No. 665,386

Claims priority, application Switzerland `Iune 18, 1956 1 Claim. (Cl. 4274) The present invention relates to a butt for firearms, particularly for those firearms which have to be supported on the soil for taking the recoil, e.g. when using the usual army ries for ring armour grenades. It has been found that such butts do not withstand such wear due to the impact reaction on the butt stock acting and are destroyed after a few shots.

It is an object of the invention to provide a lasting butt in that the same consists of resilient material and is mounted moveably relative to the firearm in such a manner that it absorbs part of the recoil.

With this and other objects in view I provide an automatic rearm comprising in combination: the iirearm proper and a butt consisting of resilient material connected moveably to the said firearm proper in such a manner as to take up part of the recoil thereof.

In the accompanying drawing an embodiment of the invention is shown by way of example.

Fig. 1 shows a butt in section before releasing a shot, and

Fig. 2 after releasing a shot.

The butt 1 consists of a resilient material of the elasticity of rubber, e.g. of rubber or a synthetic substance such as artificial rubber. The material must have a suicient elasticity, resistance to wear and tear, as well as resistance to the eiects of weather and a suicient damping capacity.

The butt 1 is attached at one end by means of a screw-threaded ring 2 on a part 3 (or extension) of the breech casing. This part 3 extends moreover into a bore of the butt, and its end 4 is guided in a sleeve 5 arranged within the butt. In order to prevent any turning of the ited States Patent C butt 1 relative to the part 3, a pin 6 is provided in the sleeve 5 which engages in a slot 7 of the part 3.

Between the end of the butt 1 which is xed to the part 3 and the abutment face 8 for the shoulder the butt 1 is provided with a cross section 9` of reduced resistance which is formed by recesses 10 and ribs 11.

After the release of the shot (Fig. 2) the butt 1 is accordingly compressed and deformed at its section of reduced dimensions 9 by the recoil movement of the part 3, whereby a substantial proportion of the recoil force is taken up and absorbed. This recoil is further damped by air cushions between the end 4 and the sleeve 5.

lWhile I have described herein and illustrated in the accompanying drawing what may be considered a typical and particularly useful embodiment of my said invention I wish it to be understood, that I do not limit myself to the particular details and dimensions described and illustrated, for obvious modifications will occur to a person skilled in the art.

What I claim as my invention and desire to secure by Letters Patent, is:

In a stock butt for a rearm having a rearwardly directed extension of a length to extend through the major portion of said butt, av stock butt completely formed of a yielding elastic material suchas rubber having a longitudinally extending bore for receiving said extension, a screw threaded ring mounted in the forward end of said butt and surrounding said extension and adapted to be threadedly connected therewith, a guide sleeve in the other end of said butt for guiding the end of said extension, a pin and slot connection between said guide sleeve and extension to prevent rotational movement of said butt on said extension, and a reduced area in said butt formed by decreasing the cross-section thereof at a point substantially intermediate the end of said butt and permit said rubber to be deformed in the reduced area to absorb recoil shock.
