IMPROVEMENT IN RjEvoLvlNe FiRE-A-iznvls,

Specification forming part of Letters Patent No. 104,636. dated June 21, 1870.l

'side elevations of the same with the lateral plates of the rear portion removed in order' to more lclearly exhibit the parts of the lock.

Fig. 4 isa vertical, central, and longitudinal section of the same. Fig. 5 isarear end view of the cylinder. Fig. Gis a side View of the bolt or safety-pivot, to be hereinafter described.

My invention has reference to that. class of revolving fire-'arms in which the cockin g ofthe y hammer and the rotating ol' the cylinder So as to bring its chambers successively iii position for being fired are effected by a single movement orretract-ion of the hammer; and my invention consists in a peculiar mode of mounting and securing the ehambered cylinder within its carrier, whereby the cylinder cannot only l be'either readily applied to or removed from the carrier,` as circumstances ,may require, but its chambers be caused to maintain a close or gastight connection with the bore ofthe barrelduring a discharge of the piece; also, in the peculiar construction and relative arrangement ,of the several parts of the lock, whereby great simplicity, strength, and compactness are at? tained.

In the said drawings, A denotes the barrel of the revolver, B the cylinder chamberior carrier, and C the main metallic portion. of the handle, all the said parts being castor formed of one piece of metal.

C C are two metallic plates, which are disposed on opposite sides of the part C.

C" C are two wooden plates, which cover 'the sides of the mainspring, and are also con nected with the part C by means ol' a screw, k. The drawings show but one ol the plates, U' 0r6,

D is a cylinder, which is provided w1 tn a series of chambers, a, arranged in a circle near its pe riphery, the said chambers extending entirely flanged heads of metallic cartridges or fixed ammunition, and thereby allow the cylinder to it closely to the breech-plate E. The Said cylinder is mounted or supported within its chamber by means of a sprngarbor, a', which.y is formed and applied thereto as shown in Fig.` 4. The said arbor basa spring,s, wound helically about it, one end of whiclrvirests against a shoulder formed on the arbor and the other against the lower end of the spring-chamber c', which is an 'enlargement of the arborcav ity c2, formed axially in the chamber. The conical or projecting end d of the Said arbor enters a shallow socket formed in the front face of the bre`ech-plate E, as shown in Fig. 4. Furthermore, the said arbor is so applied to its chamber as to permit the formerto slide entirely within the latter while the cylinder is being either introduced linto or .removed from its chamber'. Qn .the said arboror axis the cylindercan bereadilyrevolved by means of the rotating mechanism, to be hereinafter described A Inorder to prevent accidental disengagement of the cylinder from its chamber by hard or.rough usage, I apply to the outer end of such cylinder a safety-pivot or bolt,l b,which passes through-one of the walls d' of the cyl ieder-chamber B and enters a Socket, d2, made in the end of 'the cylinder. This pivot, while it allows the cylinder to freely revolve, serves' to maintain it securely in its chamber.' Furthermore, the said pivot or bolt is provided with an annular shoulder,-0, which determines the distance its conical end shall enter the cyl inder. The said bolt or pivot is prevented from slipping out of its cavity bymeans of a Screw,

Iby simply grasping ,the cylinder between the.

thumb and foreinger and pressing against the its chamber, the spring serving also-to maintain a close connection between the bores ot' the charge-chambers and the bore of the barrel when they are brought into coincidence for being red.

The mechanism for rotating the cylinder the proper distance to bring each' of its chambers successively Ainto coincidence with the bore of the barrel consists of a ratchetwheel, 1F, arranged axially on the rear end of the cylinder, and a curved traversing lever or pawl, G, which is pivoted to a projeciion, t', extending back of the breech-plate, as seen in Fig. 3, the rear end of such lever being pivoted to the slider H in such position that when the slider is drawn back so as to bring the hammer or slider H to a full-cock the front or beaked end of the said lever, operating on the teeth of the ratchet, shall give to the cylinderthe desired amount of rotation. 0n the slider beingimpelied for-v ward the front end of the lever will be withdrawn, and will be forced downward the requisite distance to take into the next tooth of the ratchet when the hammer is next retracted or set at cock.

a' is a spring, one end of which is attached to the rear part of the breech-plate E, and has its free end resting against a stud, b', project.- ing-from the 4lever G, as shown in Fig. 3, the object of suchl spring being to maintain the beak orfront of the lever G in connection with its ratchet while the hammer is being `cocked and the piece is being discharged. The said slider carries ou its front enda percussion pin or piercer,'k, which works throughy aslot or hole, o, made through the projection i and the breech-plate E. This piercer may be' so arranged as to impinge against the cartridge at any desired part of its head. 1n the present instance it is so disposed as to strike the cartridge upon its lower edge.' The said hammer slides back and forth in a direct line, being guided in its movements by the slot o, beforey mentioned, and a stud, l, (extended from the projection T,)'which works within an elongated slot, m, formed in the slider. To the rear end of the said slider one end of the mainspringI is attached by means of a loop, n, the other end thereofheing aixed to part C, as seen in Figs.

2 and il.v

To one side ofthe slider H an arm, M, is at- 1j tached, and extends down through Va slot, N,

-made through the frame'C, and carries ou its lower end a nger-loop, ho, by which the saldq slider or hammer can be set at either half'or full cock, as may be'desi'red.

K is a curved lever, which constitutes both a catch-dog and trigger, the ,same having a hook, d', formed on its front end to engage with two notches, o p,disposed on the under inclined surface of the slider. -One of the said notches, p, is formed of a peculiar shape-viz., with a sharp acute angle-so that when the hook of the dog is within such the piece cannot be discharged by means of the trigger. The lever K turns freely on a pin or stud, q, supported in projections from the frame G. The hook or catch of the dog is kept in engagement with the notches o or p by means of a spring, s. The rear end of the said lever K is provided with a short stud or cylinder, dz, which extends therel" from at right angles and projects through a hole madein the under part of the frame C, as shown in Fig. 4, such stud forming a trigger or device for releasing thev hammer 4from'the action of the dog.

On one side of the revolver a chamber or cavity, e', is made, such chamber being of'sucent size to receive a cartridge suited to the bore ot the charge-chambers. 'lhi's chamber extends through the breech-plate, so as to communicate with the chambers of the cylinder, and thus affords a means by which the cylinder may be charged without removal thereof, should it be desirable.

Afire-arm constructed in my improved man ner possesses several important advantages.

It is compact, simple, and strong, and'little liable to get out of order. Its cylinder can be readily taken out of its chamber and easily applied thereto. 'lhe lock also -is simpley and effective,the ham mer thereof moving in a strai gh t line.
