IMPROVEMENT IN REVOLVING FIRE-ARMS.

vSpecification forming part of Letters Patent No. 150,120, dated April '21, 1374; reissue N0 6,569, dated August 3, 1875; application filed July 3, 1875.

It is of course immaterial What size or diameter be adopted for said collar and groove, and whether the collar c he made, as shown, with a channel in its periphery to accommodate the portions of the anges nearest to the base-pin, or be made to surround the anges of the cartridges, and with a channel in its internal surface to accommodate those portions of the flanges most distant from the axis of motion of the cylinder.

I have represented the extractor as being formed on or out of the stock of the plate C; but this detail of construction or manufacture may, of course, be varied like others, and, if' deemed expedient, said collar may be made of a separate piece and secured in place either to or on said plate O or the base-pin of the pistol.

Having so fully described my invention that any one skilled can make and use it, what I claim as new, and desire to secure by Letters Patent, is`

A revolver lire-arm with a many-chambered breech-loading cylinder provided With ;a cartridge-extractor connected to the recoil-shield or frame of the arm, and consisting of a disk or ring, the periphery of which, that engages the heads ofthe cartridge-sh ells inthe cylinder to Withdraw them therefrom, is a true circle, concentric to the axis ot' the cylinder, all constructed and arranged t0 operate as and for the purpose described.v

In testimony whereof' I have hereunto set my hand this 1st day of July, 1875.
