CYLINDER-STOP FOR REVOLVING FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 289,821, dated April 5, 1881.

Application filed February 17, 18511. (No model.)

To all whom it may concern:

Be it known that I, HENRY MGGEE, of Norwich, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Revolve and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improvement upon the patent granted December 10,1878, to A. L.

[0 Sweet. In that patent was shown a revolver wherein the cylinder was kept from revolving by a stop pivoted to the trigger and working in a slot in the bottom of the chamber which contained the cylinder, the cylinder being provided with corresponding slots into which the stop projected.

The object of my invention is to simplify the construction and lessen the cost and labor of manufacture; and itconsists in the peculiar construction and arrangement of the stop and the parts thatopcrate in connection therewith, as fully hereinafter described.

In the drawings, laigure 1 is a central sec-,

tion of my pistol, and Fig. 2 is an enlarged detail view of the stop and spring.

In these drawings, A represents the cylinder of a revolver, and 1 1 slots on its surface, there being as many slots as there are chambers in the cylinder.

0 B is the hammer, and C the trigger, which are of the same general construction as in the patent referred to.

I) is the stop. (Shown separately in Fig. 2.) lnstead of being pivoted to the trigger, as in the patent referred to, the stop is provided with an oli'sct, 2, hich engages with the lower edge of the recoil-shield, and vith a spur, 3, which rests on a projection, 4, on the upper forward end of the trigger. The bottom of the 40 chamber which contains the cylinder is slotted, as shown, and in this slot the stop works, the lower edge oi. the recoil'shield serving as a fulcrum on which it swings. A spring, 5, serves to project the stop upward into its norand position when it enters one of the slots on the cylinder, and holds it stationary. The ot't'set 2 holds the stop in position against'any longitudinal movement, and its rear end is held up by resting on the projection i of the trigger, so thatitis secured against movement in any direction, except that necessary for its action, by means of its own construction, and that of the parts in connection with which it isplaced.

It will be observed that the upper part of the trigger is bent forward. The projection 4 will therefore rise when the upper end of the triggeris thrown back; but the upper end of said trigger is kept in contact with the rounded edge of the hammer, and the construction of this part is such that it keeps the upper end of the trigger pressed forward far enough to permit the catch to be in gear with the cylinder at the proper time.

It will be understood that the spring5 tends constantly to hold the catch in gear. The part of the hammer-piece against which the upper end of the trigger bears when the hammer is down, as in tiring, allows the upper end of the trigger to come back far enough to let the spring 5 throw up the catch into gear with the barrel; but when the piece is at half-cock the spur or upper end of the trigger falls back into thejnotch 6, and in so moving throws up the rear end of the catch and depresses its front end. sutlieiently to release it from the notch in the cylinder. As the hammer is drawn back the relative position of these parts is unchanged, and the catch is out of gear until the trigger engages with the notch 7 and is at full-cock, when the upper end of the trigger is thrown forward snliicicntly to allow the spring 5 to throw the catch or stop into connection with the cylinder. Thcrrelative movement of the rawl is the same as usual,

It will be observed, from the description already given, that the same movement of the stop is caused by the described construction as thatwhich has been accomplished heretofore by pivoting the catch upon the trigger. 9o

lilanit'cstly the construction is inexpensive, the stop being of such shape that it may be easily struck out, and thereis a saving of the expense of pivoting this part upon the trigger.

it will be nnderstooi-l that the described con 5 structiou is specially designed for revolvers of r0 edge of which acts as a fulcrum, and the spring 7. the less expensive class, although its efiicieucy 5, all substantially as described, and for the is not less than that upon which it is an impurpose set forth. provement. t In testimony whereof I have signed my name Having thus described my iuvention,what I to this specification in the presence of two sub- 5 claim as new; and desire to secure by Letters scribing witnesses.
