LOOK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Pa tent no. 263,684, dated September 5, 1882.

Application filed March 20, 1882. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. OILLEY, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented a new and useful Lock for Fire-Arms,-of which the following is a specification.

My invention relates to that class of firearms known as double-acting revolvers, in which the hammer may be drawn back to full-- cock by the use of the trigger alone, although it cannot be set at full-cock by this means, and in which one spring serves to operate the hammer, the trigger, and the revolver-lever, the object being to improve the arrangement of the sickle-lever, in connection with the hammer, and to so combine the sear with the hammer and the trigger that it (the sear) will be held, back by an 'improved'device While the hammer is making its stroke. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a longitudinal view, part in elevation and part in section. I Fig. 2 is a detail? in elevation showing the moving parts at halfcock. Fig.3 is a detail in elevation showing.

the moving parts at whole-cock. Fig. 4 is a horizontal section on line a: a: of Fig. 1. Fig. 5 is a plan of the sickle-lever detached. Fig. 6 is an elevation of the revolver-lever; Fig. 7 is a side elevation of the same, looking from the back.

The revolver-chamber B, its stop M M, and the ratchet B, not being new, need not be de-' scribed. I

(l is the hammer, swinging about the pivot C. One side of the lower part of this hammer is recessed, as-shown at the depth of the recess being just sufficient to receive the sicklelcver D, (see Fig. 4,) said sickle-lever being pivoted to the hammer O at the point D, and connected to the spring E by the link D I obtain a double joint or hearing for the sickle-lever D by forming it with a projection,

Di, and by connecting it to t l=.\ 'annner by a pin, D. By this arrangementofl passing the pin D through the lever proper and through a portion of the hammer '0' and then through the projection D I obtain a double bearing 0 for the sickle-lever to swing upon which will insure its movement in a true plane, and thus prevent it from being twisted out of its position by the strain transmitted to it through the link 1) by the spring E.

Instead of making a kert' in the lower part 0f the hammer C for the projection I), as shown in Fig. 5, a recess may be made on the rear side of the hammer to receive the part D The spring E, acting through the link 1) and lever D, serves to operate the hammer C. It also, through the same means, operates the revolver-lever F, and as the revolvenlever F is pivoted at F to the trigger K it also operates the trigger. The tension of the spring E may be adjusted by the screw E. 6

To lessen the friction of the end l) of the lever D in its action on the lever F, I insert a friction-roll at F, which is connected to the lever F by a pin orstud passing through it.

L L L is a pawl-lever or sear for holding the hammer at half-cock, as shown at Fig. 2.

L is a piston-spring, which acts upon the? sear L L L and throws it into the position shown in Fig. 2 and there holds it until the movement of the hammer to full-cock throws it out.

My means for holding the sear L L L" away from the hammer-that is, the part extending from the half-cock notchc to the point c -is made in the form of a cam, so that in drawing the hammer back to full-cock, as shown in Fig. 3, the part c on the hammer coming in contact with the part L on the sear depresses it, as shown at Fig.3. Now, when the triggerK is pulled for firing the cusp-point K of the trig- 'ger will come in contact with the point- L of the scar and there hold it until the hammer has made its blow. Then as the trigger is allowed to retreat the sear is thrown back again by the action of the piston-spring L and is ready to receive and hold the hammer at halfcock. The action of the trigger when pulled back upon the sear L L L is to bring the part K"against the forward end of the scar, and thus by mere frictional contact hold it from. moving in any direction. No part of the trigger comes in lateral contact with, the sear, so that the trigger does not under any circumstances move the sear. Itsonly action on it is to hold it for an instant during the striking; I00 movement of the hammer, so that its point Tl." cannot engage with the notch c on the hammer.

' 5 the hammer O.

The device for holding the hammer at fullcock is not new, and consists in providingthe upper end of the trigger K with a notch, k,

double joint is made between the hammer and ople'rilting together-substantially as described, and for the pnrpose set forth,

2.41116 hafniln'er.v 0, having a cam, c a, the seabl'eior L L If, and spring L, with the triggar K,,having aearved portion terminating in e cusp-point, K, whereby the sear-lever is held down by friction caused by end pressure substantially as described, and for the purpose set forth.
