SHELL EXPELLING MECHANISM FOR FIREARMS.

SHELL-EXPELLING MECHANISM FOR FIREARMS.

NO. 8&1,240.

Application filed To all 1071,0172 it may concern: I

Be it known. that I, Anonnw FYRBERG, of

Hopkinton, county of Middlesex, State of Massachusetts, have invented an Improvement in Shell-Expelling Mechanism for Firei arms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the l drawings representing like parts.

This invention relates to that class of pistols or revolvers in which the barrel, handle, and frame or body thereof are rigidly connected and the cartridge-cylinder is mounted upon a holder which is pivotally connected at its front end to the frame, so that the cylinder may be swung laterally out of its ch amber for the purpose of extracting the shells and loading the same.

My invention particularly relates to a shell extracting or ejecting mech anism for the cylinder of a revolver of the above-described character, and has for its object to provide an ejecting mechanism of this character in which. the extractor will be caused to expel the shells and return to its normal position automatically during the outward lateral movement of the cylinder.

A further object of my invention is to improve firearms of the above character in minor details, as will hereinafter appear.

I accomplish these objects by the means shown in the accompanying drawings, in which- Figure 1 is a side elevation of a revolver barrel and frame provided with my invention. Figs. 2, 3, and 4 are horizontal sectional views on the line 2 2 of Fig. 1, showing the parts in different positions. Fig. 5 is a partial sectional view on the line 2 2, Fig. 1, showing the parts in still another position. Fig. 6 is an end view of the cylinder. Figs. 7 and S-are detail views of the spring-abut ment. Figs. 9 and 10 are detail views of the actuating-lever.

As shown in the drawings, the barrel (1 is rigidly mounted in a frame or body I), having the usual chamber to receive the cartridgecylinder 0, said cylinder being revolubly mounted on the holder cl, which is mounted to swing laterally on the pivot c in the frame, 1 so as to carry the cylinder to one side thereof to permit loading. The cylinder is provided l at its front end with a projecting boss f, hav- Specification of Letters Patent.

ing an annular groovef in its outer side, and

a spring g is mounted on the holder d and provided with a pin h, which extends throu h an aperture in the holder, so that it is ri idly supported against transverse strain, an enters the groovef, so as to provide a swivel connection between the cylinder and holder, w hich. enables the cylinder to be removed readily from the holder by simply lifting the spring sufficiently to withdraw pin 1 from groove f. A locking-catch i of common form is provided to hold the cylinder in alinement with the barrel.

A shellextractor j of common form is mounted on a rod 1c, which is slidably mounted in the central bore formed in the portion of the holder on which the cylinder is journaled. Said rod 7c is provided with a shoulder 75 near its forward end, and a spring a is interposed between said shoulder and the cylinder, so that said spring normally acts to hold the extractor against the end of the cylinder in position to permit the cartridges to be inserted, all as is usual in devices of this character. An actuating lever or dog it is mounted on a pivot 0, rigidly held in the frame 7) at one side of and parallel to the ivot e. Said lever extends transversely of the holder in the rear of pivot 6 through a slot (1, formed through thereof and into which the central bore thereof leads in position to engage one end of a block which is mounted to slide axially of the cylinder in the holder, the opposite end of said block being provided with a transverse lug p, which is adapted to engage the front end of the rod 7c. The holder d is provided with a sprin -actuated pin or abutment g, which normally extends into the slot (1 at the front side of the lever a.

When the cylinder is in its normal position, the parts will be disposed as shown in Fig. 2. When the holder (1 is swung laterally on its pivot e, the pin q therein will be moved into engagement with an intermediate cam portion a on the side of lever a next pivot e as soon as the rear or outer end of the cylinder is far enough to one side of the frame to permit the shells to be moved outwardly, as in the position of Fig. 3. Further outward movement of the holder causes the pin q to swing the lever n rearwardly or toward the breech, causing it to move the block p in the the front end portion same direction, the latter thus engaging rod is and moving the extractor j to extract the shells, as shown in Fig. 4. The cam portion n of lever n is provided with a projecting end portion M, at the outer end of which is formed a groove M, which extends transversely of the .lever and is of sufficient depth and width to permit the pin 1 to pass therethrough. When the holder is swung outwardly so far that the pin 9 has reached the end if of the cam portion, the extractor will have been moved out sufficiently to expel the shell, so that upon further outward movement of the holder said pin will slip past said end. and become disengaged from said lever, permitting the spring m to return the extractor to its normal position and swinging the lever forwardly to its normal position, so that said pin 9 will then be at the opposite side of the lever from its cam n, and the parts will assume the position of Fig. 5, in which position the cartridges may be inserted.

Lever n is further provided with an inclined surface n. which extends transversely thereof from the side of the lever from cam n and the adjacent said cam portion n, as best shown in Figs. 7, 9, and 10. When the cylinder and holder are swung back to their normal positions, the pin Q will be immediately moved into contact with said inclined surface it and will be forced outwardly thereby as it is moved across the lever. When the pin has been moved entirely across said lever, it will be moved by its spring back into its normal position, (shown in Figs. 2 and 3,) so that the previously-described operation may be repeated.

Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is

1. In combination with a firearm having a rigidly-connected frame and barrel, a cylinder-holder pivoted thereto at its front end to swing laterally in the horizontal plane of the barrel, a cylinder, on said holder, a shell-extractor for said cylinder, and means operated by said holder as it is swung laterally, for moving said extractor to extract the shells, and means for returning said extractor to its normal position upon continued outward movement thereof, substantially as described.
