EUGENE G. REISING, OF EAST HARTFORD, CONNECTICUT, ASSIGNOR TO THE HARTFORD MACHINE GUN COMPANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CON- NECTICUT.

EXTRACTOR FOR. FIREARMS.

Application filed January 2, 1917.

To all whom it may concern:

Be it known that I, Eoerxn G. REISING, a citizen of the United States, residing at East Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Extractor for Firearms, of which the following is a specification.

My invention relates to the class of devices employed in firearms for removing the cartridge shell from the breech of the barrel after the cartridge has been fired, and an object of my invention, among others, is to provide a device of this class that shall be particularly eflicientin its method of operation, that shall be comparatively free from injury in the movements of the breech-bolt and that may be readily placed in position in the ln'eech-bolt or removed therefrom.

One form of extractor embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure l is a side view of a breech-bolt containing my improved extractor.

Fig. 2 is an end view of the same.

Fig. 3 is a top view of the breech-bolt with parts broken away to show the extractor in place therein.

In the accompanying drawings the numeral 5 denotes a breech-bolt, that may be of any ordinary form and construction and that is adapted to be inclosed in the receiver of a firearm and to have a reciprocating movement lengthwise therein in a manner that will be readily understood by those skilled in. the art. This breech-bolt has the usual firing pin 6 arranged and operated to strike the primer of a cartridge, the head of the shell of which is located in a recess 7 provided in the end of the breech-bolt for the reception of such head.

A bore 8 extends inwardly from the end of the breech'bolt at one side of the recess 7, this bore being of a depth slightly greater than the length of an extractor 9 to be located therein. A hole is formed in the side of the breech-bolt extending across the bore 8, the inner end of this hole constituting a well 10 for the reception of a spring 11.

The extractor has a. fulcrum l-l intermediate its ends and is provided with an extracting lip 13 at its front end, the bearing point or fulcrum being preferably located Specification of Letters Patent.

Serial No. 140,175.

about midway of the length of the extractor, the latter having a retaining lug 15 at its rear end. The extracting lip 13 is of a shape and length to fit over the flange of a cartridge shell when the latter is located in the recess 7. The end of the retaining'lug 15 extends into the mouth 12 of the well 10 and is normally located in said mouth to retain the extractor in place in the breechbolt.

TV hen the breech-bolt is moved against a cartridge in the magazine of the firearm, the curved end of the lip 13 will cause the extractor to rock against the force of the spring 11 and to pass over the rim of the cartridge shell and firmly grasp the same, and upon the rearward movement of the breeclrbolt the shell will be withdrawn from the cartridge chamber in the barrel.- \Vhen it is desired to remove the extractor, a small instrument pressed against the end of the lug 15 will disengage said lug from the mouth 12 and permit the extractor to be withdrawn from the bore 8 for the reason that the length of the lug 15 is less than the diameter of the bore 8.

In accordance with the provision of the patent statutes, I have described the prin ciples of operation of my invention, together with the apparatus which I now consider to represent the bestembodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.

I claim:

1. A breech-bolt having a bore extending inwardly from one end and with a mouth opening laterally from said here, an extractor located in said bore and having an extracting lip and a retaining lug of a length less than the diameter of said bore, the latter to permit removal of the extractor lengthwise of the bore, said extractor also having a fulcrum intern'iediate its ends and upon which it rocks to disengage its lip from a cartridge shell and the retaining lug from said mouth, and means for retaining the lug within said mouth.

2. A breech-bolt having a bore extending inwardly from one end and with a hole extending across said bore, an extractor hav ing an extracting lip and a retaining lug, the latter located in the mouth of said hole Patented July 8, 1919.

and a spring located in the bottom of said hole to press against the extractor and retain the lug in said mouth.

3. A breech-bolt having a bore extending inwardly from one end and a hole extending laterally across said bore, an extractor loca ted in said bore and having an extracting lip at one end, a projection comprising a [fulcrum intermediate its ends, a retaining lug progeetmg lnto the mouth of said hole 10 and a spring located in the bottomof said hole and forcing said lug into the mouth thereof.
