PROVISIONAL SPECIFICATION left by the said , Richard Archibald Brooman at the Office of the Commissioners of Patents, with his Petition, on the 30th December 1858.

I, Richard Archibald Brooman, of 166, Fleet Street, in the City of London, E.C., Patent Agent, do hereby declare the nature of the said Invention for “ Improvements in Revolving Fire-arms,” (communicated to me by L. F. Devisme, residing at Paris,) to be as follows : —

This Invention consists in so forming and fitting the revolving breech piece of revolving fire-arms, that when they have to be charged it may be turned either downward or to one side, or otherwise about a hinge or joint either in conjunction with or separate from the barrel, and in fixing the saidj breech piece in place after the chambers have been charged by means of a rod passing through the breech piece, and engaging at the rear end in a female screw thread or other holding part by means of a male screw thread, or a

and holds the chamber firmly closed. A pin g limits the distance the ring c travels. By the simple movement of the lever i the opening of the breech and the bringing of the ramrod into position for use are produced.

The T-piece o can be replaced by a screw taking into a corresponding thread formed in the groove in the breech. The discharge of the cartridge holders can also be produced by means of a rod terminating in a circular piece or washer, having holes formed therein corresponding with those in the cartridge holder; the cartridges rest against this washer, so that a simple push of the rod will suffice to disengage the whole of the cartridges.

And having now described the nature of the said Invention, and in what manner the same is to be performed, I declare that I claim the improvements in revolving fire-arms herein-before described and illustrated in the accompanying Drawings.

In witness whereof, I, the said Richard Archibald Brooman, have hereunto set my hand and seal, this Thirtieth day of June, One thousand eight hundred and fifty-nine.

R. A. BROOMAN. (l.s.)
