PROVISIONAL SPECIFICATION left by Thomas Wright Gardener Treeby at the Office of the Commissioners of Patents, with his Petition, on the 9th June 1858.
I, THOMAS WRIGAT GARDENER TREEBY, of No. 1, Westbourne Terrace Villas, Upper Westbourne Terrace, Paddington, in the County of Middlesex, do hereby declare the nature of the said Invention for “Improvements In Revolving Fire-Arms, And Cannon And Cartridges,” to be as follows:—
This Invention is an improvement on my Patent sealed the Tenth day of January One thousand eight hundred and fifty-six, and is for improvements in all kinds of revolving fire-arms and cannon, and for cartridges, and for plungers for striking the same, and is as follows:— The hinging of the chains to the chambers is by the side of the chambers, and not in the centre of the chambers, as shewn in the Drawing of my Patent above referred to, and the chain revolves over two pulleys or drums instead of one, that is to say, the endless chain is made tight by them and prevents the chain shaking, and allows it to revolve easily. I also make the main barrel send the charge home in the chamber of the chain by means of a screw and nut with lever, or lever and cam; by this means I do away with the ramrod. The cartridge is made in the usual way, with this exception, in the base or end where the powder is put, I place a metal ring on the end of a mandril that is hollowed out to receive it, the end of the cartridge is then turned into the ring, and a percussion cap pushed or driven in with the hollow part towards the outside, thus completely securing the cap in the centre, and firmly fastening the end of the cartridge. The cartridge is charged with powder and ball in the usual way. The strikers or plungers are attached to each chamber, fastened in the breech end, and revolves with the chain of chambers, and at the end of the iron frame I place a hammer, attached to the cock by means of a pin and cam slotted in the cock; when the hammer is pulled it strikes the plunger at the end of the chamber and explodes the cap, the ring and cap passing out with the charge; by this means the plunger is not liable to get injured by continual firing.
