IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 47,775, dated May 16, 1865.

. exactdescription of the construction and operation ofthe same, due reference`being had to the accompanying drawings.

Figure l represents a side view of a revolving pistol to which my improvements are applied. Fig. 2 represents the front end of the revolving breech-cylinder and adjacentparts. Fig. 3 represents the rear end of the same.

To enable others skilled in the art to make and use my invention, Iwillproceed to describe its construction and operation.

A represents the revolving breech-cylinder, B the frame of the pistol, D the barrel, and C the hammer. rept esents the thimbles, which are inserted into the chambers of the cylinder A, and in using metal cartridges the charges are inserted into said thimbles, the objects of the thimbles being to facilitatethe removing of the cartridge-shells after the charge is tired.

E represents a stem whose diameter is equal to the inner diameter ofthe thimbles t'. lt is attached to the barrelD by means of the sleeve K, and can be turned thereon; but it can also be secured in its position to be either in line with the chamber b or with the cha1nberc,Fig. 2, of the cylinder A. In the former case the thimble ofthe chamber b can be pushed upon the stem E afterthe charge has been tlred,and the stem E forces the empty cartridge-shell from within the thimble. The space between the end of the stem E and the face ot' the cylinder A must be sufficiently large to permit of the insertion ofthe loaded cartridges into the chambers of the cylinder A when each is successively brought into the position of chamber b. When the stem E is turned so as to be in line With the chamber c the thimbles can be removed I rom the cylinder A and from the piece, it' it is desired to clean them, Without removing the cylinder A. In Fig. l one of the thimbles (shown in red lines) is represented on the stem E.

g represents a stud, which is secured to the angular spring-rod lz, Whose lower end is pro- Ward, as shown by red lines at Fig. 2. The object of the stud g is to prevent any acci-` dental displacement ot'-the thimble when its chamber is in the position ot' chamber b, Fig. 2,as in this position the thimbleis not retained in its chamber by any part ofthe frame B, as is .the case in any other position,andwhen the thimble is to be pushed upon the stem E the knob J is pressed inward and the study releases the thimble.

' O represents the notches in the rear face of the cylinder A, through whiclrthe front end of the hammer C passes to explode the cartridges.

0 represents another series otnotches, which are made on the rear face of the oylinderAin such a position that the latter is looked by the front edge ofthe hammer at a point when the chamber b of the cylinder comes tothe position where the loaded cartridge can be inserted, thus making the cylinder self-adjusting and greatly facilitating the operation of loading. 'lhese notches serve at the same time to lock thehamlner to preventthe accidental discharge ot' thepiecewhenit is not to be used; but their principal use bengthe setting of the cylinder A for charging, their location is not discretionary, but for that purpose must be at certain points.

Having thus fully described the nature of my invention,what I claim herein as ne\v,and desire to secure by Letters Patent, s

The application to the barrel of revolving fire-arms of a hinged stem, E, for supporting the thimble and clearing itwhen removed from the cylinder A, substantially as and for the purposes described.
