BUFFER STOP FOR FIREARMS.
Patented Mar. 21, 1922.
Original application filed November 12, 1917, Serial No. 201,48. Divided and this application filed September 26, 1918, Serial No. 255,786.
7 To all whom it may concern:
ings representing like parts in each of the several views.
This invention relates to yielding buffers or stops tor use in automatic or semi-automatic-guns to afford a cushioned or resilient stop for the moving parts on the backward movement thereot resulting from the discharge oi the gun; being a division of my prior application, Serial No. 201,48d, filed November 12, 1,917. VVhile' not limited thereto in its broader aspects, the invention.
is well adapted and designed for use with a gas operated automatic or semi-automatic gun wherein a portion of. the discharge gases on a plunger member to reset the action. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description, and the distinctive features of novelty will be pointed out in the appended claims.
Referring to the drawings:
Fig. 1 is a view in horizontal section showing a portion of a gun and its receiver havingniy present improvements incorporated therewith;
Fig". 2 is a plan view ofthe same; and
Fig. is a transverse section on line 33 of Fig. 1.
The barrel of the gun is indicated at 10 with a firing chamber 11, and with a receiver 12 containing the operative parts of the action screwed to the barrel as usual as seen at 13. The breech bolt is indicated at 14: with a firing pin 15 operative therein. which breech bolt and firing pin constitutno part oi the present invention need not be further described in detail. The receiver is equipped at its bottom with a suitable cartridge magazine 16 also not involved in the present invention. To the top of the receiver 12 is slidably fitted a saddle 17, this saddle being shown as interengaged with the receiver by the interlocking slots and ribs 18 at the opposite sides of the receiver. As shown the saddle 17 is equipped in. mm

Serial No. 492,634.
with a projecting lug 19 which engages in a spiral slot 20 of the breech bolt thus constituting means for actuating the breech bolt from said saddle, and with it controlling the firing pin which is fitted in the breech bolt, in a manner that need not be specifically detailed herein. The invention is herein shown as embodied in a gas-operated type of gun and a portion of a gas cylinder is indicated at '21 extending alongside the gun barrel and receiving gas from a lateral port therein (not shown.) The )iston rod of the piston operating in such cylinder is indicated at 22 guided through a bushing 23 at the inner end of the cylinder 21 and screw threaded as seen at 24 into a lug 25 formed with and projecting laterally from the saddle 17. This lug 25 is hollow and has threaded thereinto a hollowed out handle plug 26 which serves as a housing for a spring pressed plunger pin 27 fitted into the hollow thereof, this pin having a reduced stem 28 around which is mounted a coil spring 27 to react against the head of said pin. The head of the spring pressed pin 27 is thus projected into a slot 30 xtending lengthwise in the side of the receiver and for a distance corresponding to the range of movement of the saddle 17. In accordance with my invention the head of the plunger pin 27 is beveled oil on its rear side as indicated at 31 at approximately a forty-five degree angle. and the rear end of the slot 30 is formed with a correspondingly beveled Wall 32, this wall being so located that it is encountered by the beveled "face 31 of the pin just before tne saddle reaches the backward limit of its movement. Thus the plunger pin 31 will otter a yielding resistance to the further backward. movement of the saddle and serve as a cushion stop or resilient butter preventing or minimizing concussion or hammer blow reaction of the saddle as it reaches the limit of its backward movement on its actuation by the gas at discharge, which actuation it will be understood is at a relatively high rate of speed so that the taking up of this concussion action becomes a feature of importance and significance. In practice the spring 29 will be made strong enough in proportion to the reactive force of the saddle, so that the residue of such force will be taken up and absorbed by the spring pressed plunger pin on a partial outward movement only thereof so that the pin 27 is never pressed fully out of the slot 30. The handle plug 26 is extended outward to constitute a hand hold 26 for drawing back the saddle by hand when required. aware that the invention may be embodied in other specific "forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodimentto be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention. 7
lilavingidescribed my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a firearm, a receiver, a saddle slidably fitted thereon and constituting an operating member for the action of the gun, and cooperative means on said saddle and receiver to form a yielding buffer to stop the saddle on its backward 'movement, said means-consisting in a spring pressed bevel faced element on one of said members engaging a beveled face on the other of said members.
2. In a firearm, a receiver, a saddle slidably fitted thereto and constituting the operating I am' element of the gun action, and a yielding buffer'for said saddle to cushion its backward movement, consisting in a spring pressed pincarried thereby, equippedwith a beveled rear face and fitting into a lengthwise slot in said receiver having a cooperative beveled face at the rear end thereof.
3. In a firearm, a receiver, a saddle slidably fitted thereto and constituting the operating element of the gun action, a yielding butter for said saddle to cushion its back ward movement, consisting in a spring pressed pin carried thereby, equipped with a beveled rear face and fitting into a lengthwise slotin said receiver having a cooperative beveled face at the rear end thereof, and
means for moving said saddle backward automatically on the discharge of the firearm.
In a firearm, a receiver, a saddle slid ably fitted thereon and constituting an operating member for the action of the gun, a laterally extending hand piece borne by said saddle, and a spring pressed buffer member housed in said hand piece and presenting a beveled face co-operative with a relatively fixed surface of the receiver for the purpose stated. v
In testimony whereof I have signed my name to this specification.
