IMPROVEMENT IN EXTRACTORS FOR REVOLVING FIRE-ARMS.l

Specication forming part of Letters Patent No. 204,337, dated May 28, 1878 application filed February 23, 1878.

To all whom t may concern:

Beit known that I, BENJAMIN F. JosLYN, of Worcester, in the State of Massachusetts, have invented a new and useful Improvement in Revolving Fire-Arms; and that the following 'is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, and to the letters of reference marked thereon.

The object .of my invention is to eject the shells in rapid succession from the chambers of a cylinder of a revolving fire-arm; and it consists of an ejector-bar having a projection on its rear end, its forward part being adapted to slide in a socket with a rearwardprojecting cam thereon, arranged to impin ge against the forward end of the cylinder, and held in contact therewith by a spring, and held forward out of such contact by a screw turned onto a stem on the forward end of the ejector-bar and against the front of the socket, as will be more fully hereinafter described.

Figure I is a perspective view of a revolving lire-arm having my invention applied thereto. Fig. II is a horizontal section Qf the cylinder and ejector, showing the latter thrown back, as in ejecting a shell. Fig. III is a horizontal section of the same, showing the ejector held forward, so that it will not operate to eject a shell; and Fig. IV is a vertical longitudinal section of that part of the ejector-bar which forms the cam against which the cylinder strikes at the front ends of the chambers, to operate the ejector in ejecting the shells.

In the drawings, A represents the frame of a revolving fire-arm B, the barrel; C, the cylA inder; and D, a side piece or socket secured to the side of the frame,A or to the rear part of the barrel in front of the cylinder, in which is arranged to slide the stem t' and forward part of the ejector-bar E, thelatter having a somewhat sharp-pointed projection, a, thereon, eX- tending inward a little toward the rear face of the cylinder C.

The stem t' extends through the socket D, and has a screw-thread made thereon, with a thumb-screw, F, turned thereon; and on the front part of the rod, in rear of the stem z', is a projection, c, extending rearward, and beveled on its upper side, at the extreme rear end, as shown clearly in Fig. IV, and a spring, e, is placed within a recess in the socket, with its rear end bearing against the forward end' of the ejectorbar, to force the latter rearward in a direction nearly parallel with the chambers of the cylinder.

The operation of my invention is as follows: The cartridges being inserted into the chambers of the cylinder, the thumb-screw F is turned up firmly against the front side of the socket D, which draws the ejector-bar E forward with the projection a close to the rear face of the cylinder, as shown in Fig. III. The cylinder may then be rotated and the arm discharged. The thumb-screwF is then turned partially off the stem z' and away from the front side of the socket D; and if the cylinder is turned With one of its chambers in line with the projection'c the latter will project into the chamber and allow the ejector-bar E to be forced by the spring e rearward a short distance, with the projection a a little in the rear of the cylinder, as shown in Fig. II. This be- O ing the position of the ejector when required for use, when the cylinder is rotated with the ngers every time the metal of the cylinder forming the partition between the two chambers comes in contact with the cam c the bar E is moved forward, and when the partition passes said cam the spring e forces the bar E quickly rearward. As the cylinder is revolved the forward movement of the bar'E occurs before the shellreaches the line of lsaid bar, so that as the shell passes into the line of the ejector-bar, the projection a being in the position shown in Fig. III, the flange of the shell passes in the rear of the said projection, and when the shell and the chamber which contains it are in. direct line withthe bar the cam c passes off the end of the cylinder into the front end of the chamber, and the spring c forces the bar E quickly and smartly rearward,.and the shells are ejectedfrom the rear endsof the cylinder-chambers in rapid succession as the cylinder is rotated.

The socket D may be made in a separate piece from the barrel or frame and attached thereto, as shown in the drawings; or it may eem o, and the spring e and socket D, alsul stantially as herein described.

BENJAMIN F. JOSLYN.
