IMPROVEMENT IN REVOLVING FIRE- ARMS.

Specification forming part of Letters Patent No. 143,394, dated September 30, 1873; reissue No. 5,691, dated December 16, 1873; application filed November 10, 1873.

To allwhom it may concern:

Be it known that I, ROLLIN WHITE, of Lowell, in the county of MiddleseX and in the State of Massachusetts, have invented certain new and useful Improvements in Revolving Fire-Arms; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference thereon, making part of this specification.

The nature of my invention relates to an improvement in fire-arms; and it consists in the arrangement and combination of parts, which will be more fully described hereafter.

Figure 1 is a longitudinal section of my invention. Fig. 2 is a plan view of the lockingspring. Fig. 3 is an inverted View of my invention, and Fig. 4 a modification of the same.

(1. represents the hammer or cook, which, instead of being thrown forward by a spring in the usual manner, is operated by the springrod 1), which extends backward into the handle, and has its rear end held in a socket, c, in which is placed a suitable spring, (1. The front end of this rod is bifurcated, the upper branch having a small recess cut in it, which fits over a small projection on the rear end of the hammer, and keeps the rod in position, while the lower branch strikes against a projection, c, and regulates the position which the hammer will take after striking the cartridge.

When the trigger is pulled, the spring-rod Z1 throws the hammer forward to explode the cartridge, and then allows it to recoil to the half-cock, so that the end of the hammer will not strike against the next cartridge as the cylinder is revolved. The barrel is pivoted upon the ping, and is locked in position to the top of the breech by the spring-plate h, fastened to the top of the barrel, as shown in Figs.

1 and 2. Pivoted in a recess in the rearend of the barrel is a lever or bolt, 1 which extends over the two projections, j, formed upon the top of the breech, and which serves as a lever to raise the spring locking-plate h from the rear end of the barrel just far enough to clear and unlock it from the projections j. This lever forms a stop or looks the spring lockingplate, so that it will not be strained or broken by raising the rear portion of the barrel from the breech. When the lover or bolt 1 is in the position as represented in Fig. 1, by an eccentric or cam it looks the spring-catch which holds the cylinder to the barrel, and, while thus locked, the spring-catch cannot be raised or the cylinder removed from the barrel; but, by raising the rear end. of the lever, the cam turns from the spring-catch, and leaves a space, so that the said catch can be raised and the cylinder taken from the barrel without taking the barrel. This pawl is pivoted to the piston,

2, and, as the cam pushes the piston backward it strikes against the rod 3 placed in the cylinder 4, and pushes the ejector 5 outward and dislodges the shell. Projecting at an angle upward through the spring-catch n, and through the groove 6 cut in the side of the cam Z, is a vibratory shipping-stud, 7 the upper end of which rests against the under side of the pawl, so that, by a slight upward press ure of the finger, the end of the pawl is released from the shoulder 0, when the springpiston at once flies back and releases the ejector. As the cam turns backward, carrying the pawlwith it, the under side of the pawl strikes an adjustable stop, 8, which may consist of a screw or any equivalent device, which raises the end of the pawl out of the notch, and releases the ejector automatically as soon as it has displaced the shells. By regulating the screw-stop, the point at which this release .will take place can be controlled at will. The

lcartridge-cylinder 4 revolves freely around upon a small cylinder, 9, which projects from the rear end of the barrel, as shown in Fig. 1. Placed on the pivot-hole through the center of the cylinder is the rod 3, having the ejector 5 formed on its rear end, the rod having a coiled spring placed around it to return the ejector to position after having dislodged the cartridgeshells. This cartridge-ejector is secured to the cylinder, and is entirely disconnected fronithe mechanism for operating it; wherefore the cylinder has only to be taken off from the barrel to be cleaned without unfastenin g a singlepart of said mechanism.

This cylinder can be removed from the barrel by raising the rear end of the cam-lever z and the spring-catch under it, while the rear end of the cylinder is turned up from the breech.

Instead of the sliding shipping-stud 7, as shown in Fig. 1, the spring-lever 2 (shown in Fig. 4.) may be used, or any other equivalent device which will unship the end of the pawl.

Having thus described my invention, I claim- 1. In a revolving firearm, the combination of apiston having and operated by a pawl and a cartridge-extractor disconnected from the mechanism for operating it, substantially as and for the purposes set forth.

'2. In a revolving fire-arm, the combination of a piston having a pawl connected therewith, a cartridge-extractor, and a cam station ary on the lock-frame, substantial] y as and for the purposes set forth.

3. In a revolving fire-arm, the combination of a piston having a pawl, a cartridge-extractor disconnected from the mechanism for operating it, and a cam or stop stationary on I the lock-frame, substantially as and for the purposes set forth.

4.. In a revolving fire-arm having a removable extractor, an operating-piston made separate and independent from the extractor, and

operating in a line therewith, substantially as and for the purposes set forth.

5. The adjustable stop 8 for automatically releasing or unshipping the pawl 1 at any desired or predetermined point in the act of tilting the barrel, as described.

6. The cam l, in combination with the pawl 1, stop 8, and piston for operating the can tridge-extractor, substantially as specified.

7 The combination, with a hinged barrel of a fire-arm, of the pivoted spring locking-bolt 13, having a projection, k, the slotted spring locking-plate h, and the projections j on the breech, all substantially as and for the purposes set forth.

8. The lever-cam i, in combination with the spring-catch which looks the cylinder, substantially as herein set forth.

9. The combination, in a revolving fire-arm, of the hammer a and spring-bolt I), having the double bearing shown, whereby a rebounding lock or hammer is obtained, as set forth.
