IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 194,489, dated August 21, 1877; application tiled July es, 1877.

To all whom it may concern:

Be it known that I, THOMAS M. WALLIS, of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Revolving Fire-Arms, of which the following is a speciflcation The main object of my invention is to so construct a revolving rifle or other tire-arm as to prevent the rearward projection of ignited or other particles into the face of the person ring the weapon, a further object being to construct the riiie lin sections, which may be readily put together or taken apart, and, when taken apart, will occupy but little space.

These objects I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is a perspective view of my improved revolving rifle, the sections of which it is composed being separated from each other; Figs. 2, 3, and 4, detached perspective views, showing, respectively, a portion of the stock, the side plates of the handle, and a portion of the frame, illustrating the mode of connecting the stock to the body .of the weapon; Fig. 5, a side view, partly in section, of a portion of the riiie 5 and Fig. 6, a transverse section on the line l 2, Fig. 5.

A represents a revolver of the ordinary con-v struction, except in the matter of the sideplates of the handle, which will be referred to hereinafter.

B is a barrel, of any suitable length,the rear end of this barrel litting snugly over the barrel ofthe revolver, and being provided with a spring-plate, a, carrying a pin, b, adapted to an opening in the frame of the revolver, as shown in Fig. 5.

In the present instance the rear end of this spring-plate is bent and enlarged, so as to form a guard, D, which has a portion, d, extending over the top of the frame, and two wings or ears, e e, at each side of the same. These wings or ears e e are immediately in therear of and extend some distance beyond the circumference of the cylinder ofthe revolver, as shown in Fig. 6.

In revolving fire-arms there is always more or less leakage of gases, dtc., at the joint between the front edge of the cylinder and the I rear end of the barrel, and Small particles of powder or other substances escaping here strike the front portion of the frame and are projected rearward with suflicient force to strike the face of the person irin g the weapon, if the latter is held close to the face.

It will be evident that the use of the guard D will eft'ectually prevent this rearward projecting of small particles, while at the Same time it does not interfere with the proper holding and sighting of the Weapon.

The side plates E E of the handle are provided at the rear end with projections ff, which together embrace the rear edge of the frame, and each of these projections fhas a semicircular lug, c', on which is formed a screwthread, the two lugs when the plates are in position, as in Fig, l, forming a threaded cylindrical projection, adapted to a threaded' opening, m, in a metal plate secured to the front edge of the wooden stock F of the weapon. (See Fig. 2.)

The barrel B and stock F can be easily applied to or removed from the revolver, and

when applied produce a light and easily-handled revolving riiie, which will shoot with accuracy at comparatively long ranges.

The use of the projections f and lugs c' on the side plates of the handle does not interfere with the ordinary use of the. revolver, when the barrel and Stock are removed from the same.

Neither is it necessary that the lugs of the projections f should be threaded, as shown, as the means of connection between the revolver and stock may be a bayonet-joint or other substitute for the screw, in which case the character of the lugs would be modified to accord with the change in the inode of fastening.

The barrel and stock may be applied to a 'single-barreled pistol, if desired, but the use of a revolver is to be preferred.

I claim as my invention- 1. The combination of the frame and barrel of the weapon A with the barrel B and its spring-pin b, as specified.

2. rIhe combination of the revolver A with the barrel B, provided witha plate, a, and guard 1) as specified.

3. rIhe combination ot' the frame of the weapon A with the handle-plates E, having' In testimony whereof I have signed my projections f, with lugsfor attachment to the name to this specification in the presence of stock, all substantially as set forth. two subscribing Witnesses.

4. The combination of the stock F and its T. M. WALLIS. threaded socket m with the Weapon A and its Witnesses: handle-plates E, having projections f with HARRY A. CRAWFORD,

threaded lugs z', as specified. HARRY SMITH.
