FIGE.

John M. GARFIELD, or LAKE CITY, B'IINNESOTA.

lMPROl/EMENT insult-Locks;

Specification forming part of Letters Patent No. 152,839,

dated July 7, 1874; application filed May 29, 1874.

To all whomit may concern:

Be z't known that'I, J OHN M. GARFIELD, of Lake City, in the county of Wa/bashaw and State of Minnesota, have invented a new and valuableimprovement in Gun-Locks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of reference marked tl ereorn.

Figures 1, 2, and 3 of the drawings are representations of side views of my gun-lock; and Figs. 4, 5, 6, and 7 are detail views. I I

This invention has relation to gun-locks; and it consists in a spring-anvil, which is actuated by "the hammer through the medium of a sliding wedge, and which constitutes a safety attachment to the lock thatwill prevent the hammer from striking the nipple, except when released from a full cock, as will bra-hereinafter explained.

In the annexed drawings I have represented my invention applied to a gun-lock of'a wellknown construction, A being the lock-frame, B the hammer, and O the nipple. On the outer face of the frame A, and in front of the hammer B, is an anvil, a, which is forined onthe rear end of a fiat spring, 1), which spring is rigidly secured to the frame A,,{and sustained against a shock of the hammer on its anvil by means of a stud, b.j G designates a longitinlinallymovable slide, which is arranged in rear of the spring D, and below the hammer-pivot, and which is guided by means of studs and lots 0 0. At 6 a notch is, made in the upper cc go of the slide, in which notch a stud, p, on the lower portion of the hams in'er, plays freely. The front end of the slide G has a wedge, g, formed on it, the highest point of which is flat, as indicated in Fig. 7 by the letter When the hammer is drawn back to a full cock, as shown in Fig. 2, the pin 19 will force the wedge g bet een the rear end of the spring D, so that this end will bear on said fiat portion i of the wedge. When the hammer-is let fly it will strikethc nipple and discharge the load, At the.- same time, the pin 19, acting backwardly against the slide G, together with the pressure-of the spring D on the .S1I9ilgQ;.- \XlllThIlIYQWLJJZIQk, this; slide, as shown in Fig. 3. NVhcn the hammer is half-cocked the wedge y 'will be n oycd partly between the spring D and the frame A, so that shouldthe' hammer from any accident,

'- or should it be intentionally, released,'it will be arrested before striking the nipple O by a shoulder, a, striking-the anvil a, as shown in Fig. 1. It will thus be seen the hammer cannot strikethe nipple except it be released from a full cock.

What I claim as new isl 1. The anvil a on spring D, inconibination with the shoulder a on the hammenB, and with a wedge-slide, G, actuated by the hammer, substantially in the manner and for the purposes described. f

2. The flat face i on the beveled'end g of the slide G, in combination with the'spring anvil a, and the pin 12 playing in the notch c of slide G, substantially as and for the purposes described. I

i In testimony that I claim the above I have hereunto-subscribed my name in the presence of two witnesses.
