IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part 'of Letters Patent No. 35,623, dated June 17, 1862.

To all whom it may concern:

Be it known that I, LUCIUS W. POND, of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Revolving Fire- Arlns; and Ido hereby declare that thefollowing is a full,clear, and exact description ofthe same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a longitudinal central section of the frame and niany-chambered cylinder of a pistol with my improvement. Fig. 2is a transverse section of the frame in rear of the cylinder. Fig. 3 is a side view of the upper portion ot' the frame.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to cylinder-revolvers having their cylinder-frames made to open at the lower front corner by a movement on a hinge-joint at the upper rear corner for the purpose of introducing the cartridges into the chambers from the rear ofthe cylinder; and it consists in a downward continuation ofthe upper part oi' such frame to pass over the rear of the cylinder at the point where the hammer strikes the cartridge in such a manner as to form a recoil-shield which is wholly or nearly independent of the breech-piece or usual recoil-plate and of the lower part ofthe cylinderframe, thereby relieving the said piece or plate and the hinge-joint of the strain ofthe recoil.

To enable others skilled in the art to apply my improvement, I will proceed to drscribeit with reference to the drawings.

AB G is the piece which constitutes the bottom and back ofthe cylinder-frame and the frame ot' the stock, the part B being what is variouslycalled the recoil-plate and breechpiece, and coveringthe rear of the cylinder D.

E F G is the piece which constitutes the top and front of the breech-frame and the recoil. shield, the part G being the downward continuation ot' the upper part to form the recoilshield, which constitutes my invention. c is the hinge-joint, from which the movement of the two pieces to open and close at b takes place. The downward continuation G is of a width and depth to cover the rear ofthe upper chamber, which is .in line with the barrel and opposite the hammer. Its front face is square with the top part, F, of the frame and with the cylinder axis-pin C, which is secured in and aattaches the cylinder to the part E. Its rear face is beveled, as shown in Fig. 3, to enable it to tit the back of a beveled recess in the recoilplate or breech-pieceB when the frameis closed, as shown in Fig. l, the said recess being just wide enough forits reception. When thelrame is closed the front face ot' G is ilush with the front face of B, so that the cartridges in the cylinders revolve without striking the edges ot' either, and pass smoothly over the joint. Space is left between G and the rear of the cylinder l'orthe tlanged'portion ofthe cartridge.

In Fig. l a cartridge is shown in the upper chamber in red outline. i

d is a slot provided in G for the point ot' the hammer to work through. When the cartridges are tired the downward continuation Grcceives the force of the recoil, which-in its absence would be received bythe recoil-plate or breechpiece B and bring a strain upon the hingejont; but the continuation G prevents this strain.

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

The combination, with acylinder-frame made in two pieces, hinged together at the upper rear angle7 of a downward extension, G, ofthe upper part of the frame below the hinge-joint, substantially as and t'or the purpose herein specified.
