REVOLVER.

SPECIFICATION forming part of Letters Patent No. 279,197, dated June 12, 1883.

Application filed May 8, 1883.

To all whom t may concern:

Be it known that I, DEXTER SMITH, a citizen of the United States, residing` at Spring iield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Revolving Fire-Arms, of which the following is a specification.

This invention relates to improvements in the details of the construction of revolving tirearms, and is in the nature of an improvement upon my patent of December 13, 1881, No. 9,965, to which reference Inay be had, the 0bject being to combine lthe barrel, cylinder, and extracting Inechanism shown in said patent, or substantially that, with the frame of the arm in an improved manner, whereby said eX- tractor mechanism may be operated while holding the arm in the position in which it is fired, instead of having to reverse it, as in said patent, and whereby the arm is brought to such a position that said extractor mechanism is more conveniently operated.

In the drawings forming part of this specification, Figure 1 is a side elevation of a portion of a revolving fire-arm embodying my improve ments. Fig. 2 is a plan View, partly in section, of a portion of the arm, showing the parts thereof in a position to operate the extracting mechanism. Fig. 3 is a section on the line x Fig. 1. Fig. 4 is a front end view, showing the cylinder swung away from before the ren coil-plate. g

In the drawings, a is the barrel of the arm, having thereunder the boss D, and having an arm, a2, thereon, extending over the top of the cylinder b, and provided with a hook, e, which engages with a projection, o, on the frame on, above the recoil-plate x. A stop-catch, c, is hung near the end of arm a2, and projects sufficiently above the latter to form a rear sight for the arm. Said catch cis pivoted in arm a?, and has a nose thereon, as shown, which passes through said arm into the space within hook c, and is adapted to engage with a socket, o, in the end of the projection 0 when the cylinder is locked in the frame.

An arm, L, 011 the frame -m' extends forward under the cylinder b, and to the end thereof is pivoted the barrel a, and the parts directly connected with o attached thereto, by a pin or (No model.)

screw, s, which passes through the end of boss D and into the end of arm z.

The construction ofthe base-pin y, cylinder b, with its neck, and the bead I0, the extractor n, with its stem (l, and its spring, is substantially like the similar parts of the arm shown in my said patent.

The catch c in this arm is differently constructed from the catch d in said patent, in that its engaging-points act against the sides ofthe extractor-stem and the neck on the cylinder, instead of under them.

The operation of my improvements is as follows: To load the arm the end of the catch c is borne down, lifting its nose out of the socket o, and arm a2 is pushed to the right, swinging t-he barrel and cylinder on the end of arm lzy over sidewise, asin Figs. 2 and 4t, carrying the rear end of the cylinder clear of the recoilplate x. The cartridges may then be inserted into the cylinder from the rear, and the latter and the barrel are then swung back to the position shown in Fig. 1 catch c there firmly locking them, and the arm is ready to be tired. After the cartridges have been discharged the barrel and cylinder are swung off to one side, as before, the cylinder is drawn back, in Fig. 2, pulling the stem d out until the forward catch onzengages in the groove therein, when it is suddenly moved forward away from the extractor' 11, whereby the carfridge-shells are extracted from the cylinder. The forward movement ofthe cylinder is continued, carrying the bead or rim yw on the neck ofthe cylimlcrumler the catch z, vlifting it out from the groove in stem (l, and allowing the extractor-spring to operate and force the stem back to the position it occupied before the cylinder was drawn back, as shown in Fig. 2. The arm may then be reloaded, as before described, and shut.

Vhat I claim as my invention is- 1. The combination, with the frame of a revolving firearm, having an arm, 71, extending forward, of a barrel pivoted to the end of said arm, and having the arm at thereon extending over the cylinder, and engaging by a lateral motion with the vframe over the recoil-plate, and carrying upon its base-pin a cylinder and shell-extracting devices, sul'istantially as de IOO ' direction of the plane of the face of therecoil# plate, to carry the cylinder beyond the latter and permit it to have a reciprocating,` motion upon said base-pin rearwardly beyond said recoil-plate.

2'. The combination, with the frame of a revolving,` fire-arm, of a barrel pivoted 011 said frame carrying,` a cylinder and sliell-extracting,` devices, substantially as described, adapted to be operated by moving the cylinder reciprocatingly on its base-pin, capable of being,` swung on its pivot to move the cylinder to one side in a line with the face of the recoil-plate, to permit the cylinder to have a reciprocating,` motion rearwardly beyond' said plate.

3. The combination, with the frame and barrel of a revolving {ire-arm, of a cylinder and shell-extracting devices, substantially as described., adapted to be swung to one side in 2o the direction of the plane ofthe face of the recoil-plate, beyond the latter, to permit the cylinder to have a reciproca-ting motion rearwardly beyond said plate.
