REG-OIL MECHANISM FOR FIRE ARMS.

No. 294,402, Patented Mar. 4, 1884.

I Ave-111 01 mi es?! 4 city of Philadelphia-county of Philadelphia, and State of Pennsylvania, have invented a Y tional view of oneform of my device applied made wholly of india-rubber or other elastic a F, thereby forming a yielding cushion for the the air-chamber, the air refills it, and the classhape ,or walls composing the sameand forming a of my device constructed of non-elastic or air from said chamber.

. SPECIFICATION forming Application filed April m of Letters Patent No. 294,402, dated March 4, 1884.

20. 1853. at, model.)

To aZZ it may concern.- v

Be itv known that I, JOHN .P. ONDERDONK, a citizen of the United States, residing in the new and useful Improvement inFire-Arms and Ordnance, of which the following is a specification; Y

Myinvention relates to devices for resisting the recoil of fire-arms and ordnance.

In the drawings, Figure 1 is avertical secto the stockof a gun or rifle, the'device being material; A is the stock of the gun or rifle; B, an airchamber; G, G G, and E, the sides false stock. F is a vent for the escape of air from the chamber B.

Fig. 2 is a vertical sectional view of a form semi-elastic material, in which A is the stock of the gun or ride; A,,a boss rearwardly extending irom the stock, which is cut away to form it. B is' an air-chamber inclosed by the false stock E. G. are springs to hold the false stock air from the chamber B. Fig. 3 is a vertical side View, partly in ,ele-

plied to a cannon, H, in which. B is an airchamber;.G', a spring; J, a piston or tongue ber Band attached to the trunnion I. p The device is double, one set being upon each side,

- he mode .of 'operation of my invention is. as follows: In Fig. -1, when the gun is discharged and the recoil takes place, the sides- G G of the chamber B, being of elastic mate chamber expanded underordinary pressure against the shoulder,) collapse, and the air in the air-chamber is forced out through thevent resistance .of the recoil of the gun.

The vent for the escape of airimay be of any desired form or size, or .in any suitable position with respect to the air-chamber. Upon the outside pressure being removed from tic sides GG bring it back to its original In 2 the false breech is made of wood or of any non-elastic or semi-elastic material,

and the stock A is cut away in such manner that a boss, tongue, or piston is formed, as represented at A. A false breech or cap, E, of wood or other non-elastic or semi-elastic material is then slipped over the tongue A.

' The cap E is retained and permitted to slide upon the tongue A by means of the pin f,

which Works in the slide a.

F F are channels or grooves for the escape of air from the chamber B. When the gun is discharged, the tongue A is forced back' into-the. lair-chamber B, andthe air therein, being compressed by the recoil, escapes through the grooves F F. The springs G serve to adjust the. cap E and again extend the air-chamber after the recoil of thegun has taken place and thepressure from the outside of the cap E has been removed.

The operation of the device shown in Fig. 3 is similar to that of' the devices shownin Figs. 1 and 2-that' is to say, when the cannon is discharged, the force of the recoil acts upon the tongues J, by which they are forced into the air-chambers B, the air therein escaping through the channels or grooves F.

It is obvious that the form of my device, as well as the material from which the same is constructed, may be varied without departure from the spirit of my invention, the essentialfeature of which is that the recoil of the gun isresisted by the air in the chamber, and is controlled by the escape of the air from said chamber through an air-vent provided for that purpose.

I am aware that recoil mechanisms have been employed inwhich the recoil of the gun has been resisted by the compression of air in a suitable chamber, and controlled by the ej ection of water from a containing-chamber by means of said recoil. Having thus described my invention, I claim j A device for resisting the recoil of firearms and ordnance, which consists in the combination,'with the gun, of an air-chamber prov'ided with an air-vent in such manner that the recoil of the gun is resisted by the air in said chamber and controlled by its gradual escape through said vent to the atmosphere.
