IMPROVEMENT IN REvoLvlNG Fles-ARMS.

Specification forming part of Letters Batent No. 38,321, dated April 28, 1863 Reissue No. 1,694, dated June 7, 1864.

York, did invent and make a certain new and useful Improvement in Revolving Fire-Arms; (for which Letters Patent of the United States were duly granted the 28th day of April, 1863,'

and the entire ri ght therein has been assigned toV THE MooREs PATENT FIRE-ARMS COMPANY, of Brooklyn aforesaid, asby reference'to an instrument recorded in the United States Pateat Oiice, J une 1,1863, in Liber Y6, page 126, of lTransfers of Patents, will more fully app`ear;) 'and the following is hereby declared to be a full, clear, and exact description of the said invention, reference being had to the an- -nexed drawings, making part of'this specitication, whereinl Figurel is a side elevation ot' said fire-arm. Fig. 2 is a similar view, with the barrel and cylinder in section. Fig. 3 is an end view, and Fig. 4 represents the rear end of the cylinder.

Similar marks of reference denote the same parts.

The nature of this division ofthe said invention consists in a moving gate that allowsfor the introduction or removal of the cartridgecases at the front end of the chambers, and prevents said cases dropping Vout or sliding forward and becoming obstructed. l

In the drawings, a is the handle, otany usual character or shape. b is the barrel, ricd or plain. lc is the bracket ofthe barrel, receiving the center-pin d, onv which the cylinder e revolves. j' is the arm extending fromthe handle a to the bracket. g is the trigger, and h the hammer.

The means for rotating the cylinder, the stop to the same, or the construction of the lock form no part of the present invention, as they may be made and act iu any usual manner.

The cylinder e is formed with chambers 1 1, that do not pass entirely through, but terminate at an abutment, 2, Figs. 1 and 4, at the rear end of the cylinder, which abutment leaves about one-halt'of the chamber open at the rear end, and this abutment 2, being circular, re-

volves, with the-cylinder e, beneath an abutment, 3, projecting from the handle, which abutments 2 and 3 sustain the base ot' the metallic cartridge-case, when exploded, on the line of the barrel; but the abutment does not ex tend all around, so that the rear ends of the chambers are partially open for the introduction of a,rammer to press out van exploded case, or for observing whether the chamber is loaded or not, and to allow of the removal ot' dirt from the chamber.`

The metallic cartridge-case i is formed with a teat or hollowprojection, 4, at the center of its base, entering a notch or hole in the abutment 2, and this teat is to be vfilled with fulminating material and varnished over, or a small piece of paper introduced to keep the gunpowder from contact therewith, and the ham- Ymer h is formed with a projecting point, 5, that passes through a mortise in the abutment 3 and strikes upon the side of this teat 4 and explodes the fulminate by the compression ot' the teat against the side ofthe abutment 2. In place ot the hammer being formed with a point, it may strike upon a small spring-punch, which shall act against the side of the teat.

The forward end of each chamber' 1 is .recessed to receive the flange or ring around the forward end ot' the metal cartridge-case;y -and this ange or ring being larger than the caliber of the barrel, the said case cannot slide forward and-become obstructed in the rear end of the barrel, aswould sometimes be the case were the metallic case used without this flange or ring.

In order to introduce or withdraw the cartridge-cases, the side of the bracket c is recessed, as at 7, which allows free access. to one chamber at a time. In this recess the swinging gate o' is introduced on the center' 8. When the same is turned back, as shown by dotted lines'in Fig. 1, a cartridge-case can be'eutered or withdrawn; but when the same is turned up into the recess thev end ot' the gate keeps the cartridges from falling out. A small projection springing into a notch keeps this gate in position when turned up, and a thumb-piece,

9, allows for its being pressed down out ofthe way when desired.

What ls claimed as the invention of' the said DANIEL MOORE, and to be secured by Letters Patent, isf A movable gate applied at the forward end ofthe cylinderfto retain the metallic cartridgecases when in the chambers or allowof the introduction or removal of suoli eases after said gate has been moved aside, Substantially as specied.
