IMPROVQEMENT INV'EXTRACTO'RS FOR REvoLviNe FIRE-ARMS.

Specification forming part of Letters Patent No. 198,745, dated January 1, 1878; application filed .June 6,1877.

To all whom it may concern.-

' Be it known that we, OWEN JoNEs'and 'FRANK'W. MARSTON, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new anduseful-Improvement in Cartridges and Extractors; and

- we do hereby declare that thefollowing is a full and exact description of the same, refer.- ence being had to the accompanying drawing; and to the letters of reference marked thereon.

This invention consists, mainly, in the combination of certain independent mechanism,

for extracting the cartridgershells with certain independent mechanism for changing the shape or position of a portion of the cartridgeshell to bring it within the range of the'extractin'g mechanism. I I a It consists, further, in certain details of construction, which, in connection with theiforegoing, will be fully described hereinafter.

A general statement of the method may be ma'deas follows: The cartridges havingbeen first" arranged in the cylinder in such. manner as to be entirely independent of theextraotor, but in, close proximity thereto, are then successively exploded in the usual manner by the impact of the hammer. .By this impact, also, a portion of the cartridge-shell is forced out have been exploded; Fig. 5, asimilar view .with' one cartridge only exploded; Fig. 6,

views of the cartridge enlarged; Fig.7, views of the extractor-sleeve and center-pin; and Fig. 8, an end elevation of the cylinder, in which the cartridges are shown, separated from the extractor, by a dotted circle.

To enable others skilled in the art to use our method, and the devices employed in connection therewith, we will now proceed to describe the same fully, and the construction and operation of the'devices.

' A represents the'frame of the pistol, and B the barrel, which may be constructed gener ally in theusualwell-known orotherpropermanv.

ner. O, Figs.2and 7, represents a center-pin, projecting forward from the frame a proper dis,- tance, which is screwed into place in theusual manner, and is provided with the head 0, as shown. D represents a sleeve, locatedon the pin, between the head sand the frame, which is adapted to turn freely thereon, and is provided at its extreme rear end with a ratchetface, d, and adjacent thereto with an annular flange orshoulder, d, and an annular'groove or recess, 9?.

rigid connection is made with the cylinder, as

far as revolution is concerned, without afiect- I ing the fieedom of its longitudinal movement.

E represents the cylinder, constructed generally in the usual well-known or other proper manner, but provided with a longitudinal groove or recess, 6, and an annular recess,c,

at its rear end. F represents the hammer, whichv is constructed generally in the usual manner, and operated-in the ordinary way,"

but which isprovided with an explodingpoint, f, so arranged as to strike, when re-Y leased by the trigger, behind the shoulderd of the extractor-sleeve down into the recess d as shown in Fig. 2. G, Fig. 6, represents the cartridge-shell, which maybe of'the usual well-known construction, but which is prefera:

bly provided with an auxiliary flange or projection, g, extending in a rearward direction,

- as shown.

This special cartridge is not claimed per se in this connection, as it will be made the subject of a separate application for a patent.

When the parts are in their proper position, as shown in Fig. 3, it will be observed that the cartridges and the extracting device are located in independent planes, and that the former are not either in contact with the latter, or within the line of its action, the annu lar flange of the extractor occupyinga central space, which lies wholly within the circle 00 in which the cartridges are located, as shown in Fig. 8.

The operation-will be readily understood. The pistol, after havingbeen properlyloaded, may be fired in the usual manner.

61 represents a stud or projec-' tion near its front end, by means of which By the descent ofthe hammer the cartridge, of course, is exploded; but in addition, also, to this result, a portion of the flange is turned over into the recess d behind the shoulder or flange of the extractor, as shown in Figs. at and 5. In consequence of this change of shape or position it follows that when the cylinderis drawn forward the shell cannot move with it, because it is held by the contact of its projecting portion with the fixed shoulder; hence the shell may be extracted by simply drawing the cylinder away from it in. the usual Wellknown manner.

It will be observed that onlythe shells which are struck by the hammer will be caused to engage with the extractor, and hence that, in the act of extracting, loaded shells will never be disturbed under any circumstances. If desired, the ordinary shell may be employed; but the form shown, or some equivalent form, is preferred. A- rim-fire cartridge also is preferred; but, if desired, a centralfire cartridge may be used by adding to the hammer aproper projection to explode the same.

This invention is especially adapted for that class of revolvers covered by Owen J ones patents of June 20, 1876, No. 179,026, and April 10, 1877, No. 189,360 but it may be applied also, to the Smith 86 Wesson extracting-revolvers, if desired, and to any others of suitable construction.

WVe do not limit ourselves to the use of the hammer for upsetting the metal of the cartridge, as auxiliary mechanism may be employed for this purpose. I

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination of the following elements Independentmechanism, substantially as described, for extracting the cartridge-shells, and independent mechanism, substantially as described, for changing the shape or position of a portion of the cartridge-shell to bring it within the range of action of the extracting mechanism.

2. The combination of the following elements An independent extractor, a cylinder, substantially as described, adapted to hold the cartridge out of the line of action of the extractor, and mechanism, substantially as described, adapted to act on the rim of the shell and cause it to engage with the extractor.

3. In combination with the cylinder E, the

6. In combination with an extractor lying out of the plane of the cartridge, and having a recess, a hammer-head adapted to enter the recess, as and for the purpose set forth.

7. The combination of the following elements: A cylinder adapted, substantially as described, to hold a series of cartridges out of the line of action of the extractor, a central extractor adapted to receive the projection of all the cartridges of the series after the forms of the shells have been changed, and mechanism, substantially as described, for changing the position or form of the rims of the can tridges. I

8. The method described of extracting cartridge-shells, consisting, essentially, first, in locating a series of cartridges in the cylinder in a circle concentric with a central extracting device, but out of the line of the extractors action; second, changingtheshape or position of the rims of two or more cartridges, when the latter are exploded, to bring them within the range of the extractors action; and, third, actuating the extracting device to simultaneously remove all the exploded cartridges.

This specification signed and witnessed this 4th day of June, 1877.
