EDWARD L. SARGENT, WATERTOWN, NEW YORK.

Letters Patent No. 104,502, lla-ted June 21, 187 0t IMPROVEMENT IN BREECH-LOADING- FIRE-ARMS.

m The Schedule referred to in these Letters Patent and making part of the same,

To all whom it may concern Be it known that I, EDWARD L. SARGE'NT, of Watertown, in the State of New York, have invented a new and useful Improvementin'Breech-loading Fire- Arms; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, reference being had to the accompanying drawingand letters of reference marked thereon making a part of this specification, in which- Figure l is a sectional elevation.

This invention is an improvement over that for which Letters Patent No. 100,445, dated March 1, 1870, were granted me, and relates to the mechanism for setting the hammers at half or quarter cock.

In my former invention the mechanism for this purpose consists of a cam-groove in the rotating canipiece; a pin, one end of which is received in said cam-groove, and which slides in the breech; an arm extending downward from the transverse shaft which bears the cooking-finger; and a spring which serves at all times to hold the arm with a yielding pressure against the pin.

To enable those skilled in. the art to make and use my invention, I now'procecd to describe its construction and operation.

Similar letters in the drawing refer to like parts.

My present invention consists of a bar sliding freely in the breech, from which a pin projects, into a recess in the rotating cam-piece, and which is transversely grooved in its upper side near its opposite extremity, into which groove the arm of the transverse shaft which bears the coeking-nger extends, by which arf rangement the spring ofthe former mechanism is dispensed with, and the movement of the cocking-nger made positive in both directions, so that 1t may be made to operate the hammers either when the 'sliding bar is moved backward or when it is drawn forward. f

D is the rotating cam-piece;

a, the recess made vertically in the same;

b, the sliding bar;

c, the'pin projecting from the sliding bar into thc recessa;

d, the transverse groove of the bar;

e, the arm extending downward into thegroove ll from the transverse shaft 7|; and

'12, the cooking-finger.

This mechanism is much less liable to get ontfof' order than the other, owing tothe absence of the spring, whieh, in 'the former apparatus, e'ectsthe forward throw f the sliding bar, and to the connection of such bar with the cam-piece in such a manproduces. every movement of the ner that the latter former.

What I claim as new, and desire to secure by Letters Patent, is y The combination of the coeking device with the rotating cam-piece by means of the sliding bar, when the latter is so connected with the cam-piece as to be directly operated in all its movements thereby, substantially as described.
