Be it known that we, Samuel Norris, of Springfield, Massachusetts, United States of America, at present residing in London, England, and Wilhelm Mauser and Paul Mauser, both of Oberndorf on the Neckar, in the Kingdom of Wurtemburg, have invented certain new and useful "Improvements in Breech-Loading Fire-Arms"; and we do hereby declare that

Patented June 2, 1868.
QSie&t+jtcuiq the following is a full and exact description thereof, reference being had to the accompanying drawings forming a part of this specification.
The said improvements relate, first, to breech-loading mechanism of novel construction for fire-arms, whose breech is closed by a cylindrical block fitted to slide endwise in a chamber at the rear of the barrel. The said block is provided with a catch or projection extending from its surface, and, to close the breech, is turned upon its axis, so as to bring the said catch in front of a shoulder on the side of the breech-chamber, and thereby keep the said block securely up to the breech. In opening the breech, the catch is turned back into line with a longitudinal aperture, which allows the said catch to pass, and the block to be drawn back.
The cartridges are ignited by the blow of a firing-pin, which passes through the cylindrical block, and is driven forward by a spring, which is held by a catch, and is released by means of an ordinary trigger.
The said improvements consist chiefly in the peculiar construction and arrangement of the main-spring, and in the devices employed in connection with the trigger for holding and releasing the said spring. The latter is attached at one end to the extremity of a handle, which projects radially from the rear of the cylindrical breech-block, the other end of the said spring being free, and arranged exactly opposite the centre of the said block, which is in line with the barrel.
The rear end of the firing-pin lies in contact with a head formed on the end of the spring, and when the latter is released from its catch, it drives the said pin forward into contact with the cartridge in the charge-chamber. The said pin is kept in contact with the head of the main-spring by a light spiral spring, which bears against the rear end of the pin, and the. forward end of the breech-block.
The head of the main-spring lies close to the end of the cylindrical block, except when the piece is cocked, and is formed with an inclined surface or cam. This surface is arranged to act in such a manner upon the catch or stop that when the cylindrical block is turned in the proper direction upon its axis, the main-spring is forced back behind the said catch, the piece being then cocked. This movable stop is fixed upon the end of an elastic bar, which is secured at its forward end to the under side of the metal shoe, wherein the breech-chamber is formed. This bar is so formed and arranged that, when free, its elasticity forces it upward, and keeps the catch in its proper position to hold the main-spring back.
A central longitudical aperture is formed in the elastic bar to receive a small arm, which is pivoted in this aperture near the rear end of the said bar. The free end of this arm lies in contact with the under surface of the
