IM PROVEMENT IN REVOLVING Fl RE-AR M S.

Specification forming part of Letters Patent No. 27,868, dated April 10, 1860.

To all whom it may concern:

Be it known that I, FREDERICK -D. NEW:

BURY, of the city of Albany, State ofNew l Toward itsfront edge is pivoted a bar or link, =f, which'by'it's other notched end, fitted to a pin, 19, upon the trigger, maintains the connec- York, have invented certain Improvementsin the Oonstructionof Fire-Arms; and I declare the following specification, withthedrawings hereto attached as part of the-same, to be a full and perfect description of my invention.

Figure 1 represents in profile the skeletonframe of the handle of a pistol, the covering plate and wooden gripes being removed, to show the mechanism of the lock, the'position of its parts being as ready for firing-by the trigger. Fig. 2 is the representationof the parts with the hammer cocked and ready for firin Fig. 3 is a perspective view, showing the mechanism in reverse of Fig. 2. Fig. 4is a diagram to show a peculiar method of attaching the mainspring to the hammer.

Similar letters in all the figures denote the same parts of the apparatus.

My invention applies directly to revolvers, but may be used to some extent in the locks of common fire-arms.

A is the skeleton stock frame, holding the usual revolving cylinder, 0. This cylinder turns upon a shaft or axis, X, extending through its length, carefully fitted,so that the cylinder can be easily slipped from it, but by a feather and slot, pin and notch, or other convenient device, so fitted that the revolution of Xshall carry the cylinder with it. The front end of the shaft rests within a cross-bar, Y, forming the end of the frame A, and its rear end through the face plate or bar D, behind and against which it carries the ratchet wheel B, firmly attached to it, (the shaft.) Bythis wheel the cylinder is turned through the action of shaped leverV and the trigger T. The edge of wheel R is cut into ratchet-teeth corresponding with the number of chambers in the cylinder-five for a fiveshooter, six for a sixshooter.

The trigger T, shaped as shown in the drawings, is pivoted to the frame at c, and has projecting from its upper back corner a limb, a, fitted to conform to the space between the teeth of B, so that when the trigger is held back in the act of firingthat is, is moved a little back of its position, as shown in Figs. 2 and 3-it shall block the wheel, holding the bores of the chamber and barrel in line with each other.

The hammer H is pivoted to the lrame at h.

'tion of hammer and trigger, so that the drawingof the latter shall throwthe former bacle Toward the bottom of the hammer the ward.

balancecatch-lever g is pivoted, having at its front'end ahook or catch fittedto hold onto 1), its back end being so shapedthat when by -the-movemcnt of thehammer it is thrown forward it can be canted upward by-a projection in the frame or pin placed at m for the purpose. This movement is to direct the hook end toward the pin 1), as hereinafter explained, and for the same purpose the back end of the lever is stopped by appropriate means upon or against the hammer.

To guide the movements of bar f, it has a pin, d, projecting back through a slot, it, made through the trigger, and against this pin a spring, u, Fig. 2, attached to the frame, is arranged to press the notch of the bar over pin 19 when hammer and trigger are both down, as in Fig. 1.

The -shaped lever V is attached to the frame behind the hammer, and is operated by a pin, k, projecting from the end' of limb or of the trigger, as shown in Fig. 3. It has a small spring lying behind it, which cannot be shown in the drawings, to keep it pressed habitually up from the frame toward the trigger.

The trigger T is kept in its proper position,

when at rest, by sear-spring Z.

The operation of the mechanism is as follows: The cylinder being loaded and capped and the parts of the lock in the position shown in Fig.1, a pull upon the trigger, pressing upon pin p, throws the hammer backward by the barf, and continues to move it back until the progress of the bottom of the hammer carries lever g so far forward that it passes underpin p, when it tripsffrom the pin and the hammer falls. During this movement the upper limb of lever V, lifted by the pink on the trigger, passes under and presses up one of the teeth of the wheel R, turning the cylinder until one of the chambers is in range, or nearly so, with the bore of the barrel, bringingacone and cap in the range of the hammer, the last movement of the trigger bringing its end a firmly against and blocking thewheel as the hammer falls. As soon as the trigger is relieved it is thrown back by the searspring, and in its progress downward .pin It, pressing upon the lower limb of V, carries the upper limb downward along and below the ratchettooth, against which it laid,and is then bythe pressure of the spring beneath it thrown under the tooth, ready to lift it on the next pull of the trigger. At the same time barf, forced by the action of spring it upon pin 01, takes its place upon pin 19, and all is ready for another fire.

This piece can also be cooked by hand, for it will be seen that by raising the hammer the trigger will follow until lever 9 trips when, as the hammer is held from falling at themstant of the trip, time is given for the catch at the end of g to slip over pin 19 and hold the trigger from falling back until it is pressed by the finger back a small distance, which lifts the pin until it is disengaged from the hook, when the hammer falls and the trigger falls back to it first position.

What I claim, and desire to secure by Letters Patent, is-

1. The apparatus for enabling the hammer and trigger to be operated in concert with each other, whether the hammer be set by hand or by the trigger.

2. The bar f, attached to the hammer and working along the side of the trigger in order to catch into the pin p, in combination with the balance catch -1ever g, operating as described.

3. Pin d in bar f, operating through the slot t, and in combination with it and spring u, or the mechanical equivalents for said apparatus, the whole operating together in manner and for the purposes set forth.

4. The combined action of the trigger and pin 76 with lever V in operating the cylinder, so that when the lever has turned the cylin' der to bring a chamber in it and the barrel to coincide the toe or front point, a, of the trigger shall, jointly with the pin 70 and the lever V, hold the cylinder during the discharge of the piece, in the manner herein shown and described.
