IMPROVEMENT IN BREECH-LQADING FIRE-ARMS.

U Specification forming part of Letters Patent No. 133,063, dated November 12, 1872.

To all whom it may concern:

Be it known that 1, WILLIAM SYDNEY SMOOT, of Ilion, county of Herkimer and State of New York, have invented a new and useful Improvement in Breech-Loading Fire- Arms, of which the following is a full and exact description, reference being had to the drawing forming a part of this specification.

My invention is designed with reference to that class of breech-loading fire-arms in which the ignition of the charge is effected through a firing-pin, which receives the blow of the hammer and transmits it to the cartridge; and my said invention consists in the arrangement and combination of a lever pivoted to a solid breech-block, and connected at its upper end with the firing-pin, and kept in contact at its lower end with a fixed stud or shoulder by means of a spring, by which, when the breechblock is swung away fromthe chamber to permit the insertion of a cartridge, the lever is caused to ride over the shoulder, and by an angular movement withdraw the firing-pin into the breech-block but when the latter is closed the bearing of the lever upon the shoulder will hold the breech-block in such position.

In the accompanying drawing I have shown my invention as applied to what is known as the Remington rifle; but it is equally applicable, with certain obvious modifications, to any other form of breech-block, whether the same swings from a center above or below the axis of the barrel, 0r slides transverse to or parallel with the axis of the barrel in closing or unclosing the chamber.

Figure 1 is a longitudinal section through the barrel and breech-block, a portion of the side of the frame being removed for the purpose of showing the operation of the several parts. Fig. 2 is a front view of the breechblock.

In Fig. 1 the breech-blockB has a slot in its rear portion for the reception of a lever, O, pivoted to the breech-block at or near the center of its length, and capable. of a limited amount of angular or vibratory movement. The upper end of this lever takes into a notch in the firing-pin E, and its lower end is kept in contact with a pin or stud, D, on the frame by means of a spring, S.

It will be observed that the notch in th firing-pin is wider than the end of lever O by an amount equal to the movement of the pin.

The mode of operation of the above is as follows: When the breech block is swung away from the chamber to permit the insertion of a cartridge the lower end of lever (J rides .over the stud D, compressing the spring S,

thereby moved forward, leaving the firing.

pin free to be driven forward by the hammer without imparting any motion to the retractor.

When the firing-pin reaches the end of its for ward movement it comes in contact with the upper end of the extractor-lever, and the several parts are then in position to repeat the series of operations just described.

It will be observed that the piece 0 is thus caused to perform the double function of withdrawing the firing-pin and holding the breech in its closed position.

Having thus described my invention, what I claim is- 1. In a breech-loading fire-arm having a solid breech-block, the combination and arrangement of the lever G, pivoted to the breech-block, with the firing-pin E and fixed shoulder D, to operate substantially as and for the purpose herein set forth.

2. In combination with the lever O, pivoted as described, and the fixed shoulder D, I claim the spring S, arranged to operate as described, whereby the breechblock is held in its closed position, as set forth.
