IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 35,657, dated June 17, 1862.

To all whom t may concern:

.Be it known that I, JOHN H.V1o1inas, of Worcester,-in the county of Vorcester and State of Massachusetts, have invented a new and useful Improvement in Revolving Fire- Arms; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specieation, in which- Figure 1 is a side view of a pistol with my improvement. Fig. 21s a longitudinal central section of the same. Fig. 3 is a top view of the same, partly in section.

Similar letters ot' reference indicate corresponding parts in the several figures.

This invention consists in the employment, in a revolving lire-arm, of a continuous frame rigidly attached to the barrel, inclosing the cylinder lengthwise, and pivoted to the stock in such manner as to enable the rear part to fold into the breech-piece and to form a recoilplate independent of the breech-piece for relieving the breech-piece ot' the strain of the recoil, such frame allowing the cylinder and breech-piece to be separated for the introduction of the cartridges into the chambers at the rear thereof.

It further consists in so applying the cylinder axis-pin, in combination with such continuous frame, that it passes through the said frame and cylinder from front to rear thereof and enters a hole in the breech-piece in such manner as to secure or assist in securing the said frame in proper connection with the breechpiece.

To enable others skilled in the art to apply myinvention to use, I will proceed to describe it with reference to the drawings.

A is the continuous frame for the reception ot' the cylinder, made in the same piece with the barrel B, or having the latter screwed into or otherwise rigidly attached, the said frame being just long enough for the reception ol the many-chambered cylinder `F and of the flanges of the metallic cartridges, which are left protruding through the rear of the cha-inbers thereof.

C is the stock-frame, having the circular breech-piece D, which covers the rear of the cylinder, made in the same piece with it, and a portion of it extending forward from the bottom of the breech-piece, as shown at e, far enough for the connection with it of the lower front angle ot the continuous cylinder-fraaie A by means of a pivot or hinge-joint, a. The back ot' the frame A, which is a little wider than the caliber ot' the chambers, is tted to a groove, b, provided for its reception in the breech-piece, and the lower side of the said frame is fitted to a groove provided for it in the part c of the stock-frame.

E is the cylinder axis-pin, inserted through a hole in the frontof the cylinder-frame A,

through the center of the cylinder, through a hole in the rear of the cylinder-frame, and into a hole, e, in the center of the circular breechpiece. This pin, when secu-red in the cylinder-frame by suitable means applied near its front end, serves by its entrance into the breech-piece to secure or assist in securing the cylinder-frame to the breech-piece, but other meansforsecuring the frame may be employed.

To insert the cartridges in the chambersff of the cylinder, the axis-pin E is drawn. forward far enough to remove its rear end from the hole e in lthe breech-piece D, and the barrel and stock are folded downward from the hinge-joint a to expose the rear end of the cylinder, whose chambers are open at the rear for the reception of the cartridges. When the barrel and stock are thus l'olded down the cylinder is free to be turned by hand upon the axis-pin. After the chambers have all been loaded the barrel and stock are moved upward again relatively to each other from the joint a, and the back part of the frame is thus caused to enter the groove` b in the breech-piece, and the pin E is pushed back again into the hole c in the breech-piece. In firing, the back part of the frame A constitutes a recoil-shield independent of the breech-piece D and stock, which are thus relieved of the force of the recoil.

Whatl claim as my invention, and desire to secure by Letters Patent, is

1. The continuous cylinder-frame A, rigidly attached to the barrel and combined with the breeeh-pieceD, to fold into a. groove provided a forward direction through the cylinder-frame therein, for its reception, substantially as and and cylinder and into a hole in the center of for the purpose herein specified. the breech-piece, substantially as and for the 2. 'Hinging the lower front angle of said purpose herein specified. continuous frame A to a portion c 'of the stock-frame which projects forwer zrom the JOHN H' VIOKBRS' bottom ofthe breech-piece D, substantially as Witnesses herein specified. E. B. STODDARD,

3. The insertion 0f the cylinder axis-pin in EDWARD D. HOLTON.
