lMPROVEMENT IN RIEVOLVINGI FIRE-ARMS.

' Specification forming part of Letters Patent N 0. 193,367, dated July 24, 1877 application filed 1 August 23, 1875.

To all whom it may concern: 7

Be it known that we, SULLIVAN FORE- HAND and HENRY O. WADSWORTH, both of, the city and county of Worcester, and Gommonwealth of Massachusetts, have invented certain new and useful'Improvements in "Re- VolvingFireArms; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in.which resent the position of the hammer after the arm has beendischarged, and the manner in which the cylinder is locked and hold in the said discharged position bya lookingprojection and a projecting part of the trigger. Fig. 3 the working parts, however, being shown in different positions in full and dotted linesfull lines showing the arm at half-cook, and dotted lines at full-cock, while the cylinderis shown unlocked in full lines, and locked by back-spring locking-bolt in dotted lines. Fig. 4 represents, upon an enlarged scale, the trigger detached. Fig. 5 represents, also upon an enlarged scale, an edge view of the trigger, looking in the direction'indicated by the arrow, Fig. 4; and Fig. 6 represents, also upon an enlarged scale, a section on line A B, Fig. 5, showing very clearly the position of the backspring locking-bolt.

To enable those skilled in the art to which our invention belongs to ,make' and use the same, we will proceed to describe it more in detail.

In the drawings, the part marked A represents the frame of the arm; B, the barrel; (3, the chamber or revolving cylinder; D, the trigger-guard; E, the trigger; F,- the hammer; and G, side plate to arm, held in place in the usual manner.

' As our present improvements have special reference to a novel and special mode of looking and unlocking the cylinder at certain times-, -as will be hereinafter more fully ex- ,plained, and of holding the hammer in a safer safety-catch I) is also position while the arm is being loaded, the description will beconfined mainly to the devices by which said results are obtained,

since the other parts of the arm may be made 7 is drawn back to full-cock, either by pulling onthe trigger E or by drawing back the hammer F by the hand.

- In discharging the arm, the safety-catch b is unlocked from the safety-notcha by the pin 0 in the trigger E, lifting the forward end of the safety-catch b. At the same time the back-springlocking-bolt d in the trigger E locks the cylinder while the chamber is in line of discharge, and the point e of the trigger E escapes the flyf and allows the hammer F to spring forward an d discharge the,

cartridge. Then'the trigger-spring g forces the trigger E forward, and the projecting point It on the forward end of the trigger E looks into the forward in the cylinder 0, which also prevents the cylinder 0 from revolving when the hammer A rests -upon the exploded 'shell, or as in position shown in Figs. .1 and 2.

The cylinder is rotated by the hand or pawl 0, held in place by the pawl-spring 0". Lock- 'ing-bolt d is hinged at 2 in the trigger E.

The front end of the back-locking bolt (1 is forced up to lock the cylinder at the proper time, as above described, by means of a spiral spring, a, fitted in a hole in the trigger. The held up by a proper spring.

Those skilled in the art will readily appre- I ciate the value of our present improvements in revolving fire-arms, since by them the cylinder is securely locked when it is desired to load the arm the safetycatch b, holds the hammer securely in position.

Having described our improvements in restructed and relatively arranged for operavol'v-ing fire-arms, what we claim therein as tion substantially as and for the purposes new and of our invention, and desire to secure shown and described.
