" Jolie drawings, and

shown in. Ji F2, in which i, the oin F.

e projection, iii, extending through low'n einii uneier imperedgeof imnneeri'i forward of hammer" hammer E whenever the latter is returned to its normal position, as shown in Fig. 1, and when in this position the hammer-cannot be drawn back by the action of the trigger, or otherwise, until after the lever K has been forced down to release said hammer, as shown in Fig. 2. The upper part, L, of lever K passes through, in this instance, a-slot in the main spring D, and is also provided with two fingers, t, which straddle aguide-pin, u, fingers tiworking in a slot in the guard N. A. twoarmed spring, M, is fitted between the under side of the part L of lever Kanc the .inside of the handle-frame A, to press the free endof said lever up against the hammer E, to insure the locking thereof whenever mainspring D throws it into the position shown in Fig. 1.

From the foregoing description it will be seen that projection L must first be depressed to unlock hammer E before trigger J can be drawn back to operate the hammer, and, fur-' ther, that hammer E cannot be accidentally forced against the firing-pin, since the trigger, scar, and hammer are locked together by the action of lever K. It will be observed that the bow part only of safety-lever K extends beyond the handle, and this only in the seallopedlpart thereof; consequently the handle can be firmly grasped and held without liability of unlocking the hammer, while, when desired, by a slight depression of the center portion of the hand the bow part of safetylever K can be depressed in the scallop of the handle and the hammer unlocked. Accidental or premature firing of the arm is therefore well guarded against.

Inusing the arm the hollow of the hand first presses in projection L and unlocks hammer E, when the contraction of the finger draws back trigger J and fires the arm. Lever K, being of a single piece, locks the hammer far more effectually and securely than is the case when several parts or levers are employed for that purpose, in connection with a movable part arranged in the handle to be pressed into unlock the hammer preparatory to firing. Then, again, my arrangement of a lever, extending under the hammer and locking the same from its lower forward edge, causes the parts to work and wear more uniformly and securely than would be the case if the arrangement of parts was such as to bring the strain upon the hammer upon its upper part or above its pivot, where nearly all the other strain in operating the hammer comes. It will be understood that lever K may be arranged somewhat diflerently, and also con struoted in a somewhat different form, and yet accomplish substantially the same results and practical advantagesabove set forth.

Having described my improvements in firearms, what I claim, and desire to secure by scalloped part of the handle, within which.

said lever is hinged, of slotted guard N, guidepin a, and fingers t on the end L of lever K, said fingers straddling pin uand working in said slot in guard N, all substantially as and for the purposes set forth.

2. In revolving fire-arms, the combination, with chamber or receiverB and handle A, of 'mainspring D, provided with a slot for the passage of the end L of'lever K, and hammer E, provided with a projection, s, to engage with the lug or catch 9 on the inner end oflever K L, substantially as and for the purposes set forth.

3. In revolving fire-arms, the combination, with hammer E, provided with a circular forwardly-projecting part for the rear curved part of the firing-pin to rest and slide upon, and an upward projection, c, for striking the firing-pin, of firing-pin F, fitted to rest upon the forward curved part of' the hammer, and provided with slot f, to receive ping to limit its motion, and spring G, for retracting the firing-pin, all substantially as described.

IVER JOHNSON.
