FRANK F. BURTON, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO WIN CHESTER REPEATING ARMS CO., OF NEW HAVEN, CONNECTICUT, A COREPORATION. EXTRACTOR FOR FIREARVs. SPECIFICATION forming part of Letters Patent No. 790,615, dated May 28, 1905. Application filed December 6, 1904. Serial No. 235,731, To all whom it invay concern: combinations of parts, as will be hereinafter Beit known that I, FRANKF. BURTON, a citi described, and pointed out in the claims. Zen of the United States, residing at New In carrying out my invention as herein Haven, in the county of New Haven and State shown I employ a longitudinally-movable ex of Connecticut, have invented a new and use tractor 2, slightly bowed from end to end, so ful Improvement in Extractors for Firearms; as to form a spring, and located in a long slot3, and I do hereby declare the following, when formed in the center of the lower face of the taken in connection with the accompanying integral bolt-receiving barrel extension 4 of 55 drawings and the figures of reference marked the gun-barrel 5. Upon the upper face of its O thereon, to be a full, clear, and exact descrip rear end the extractor is formed with an op tion of the same, and which said drawings con erating-lug. 6, entering a longitudinal slot 7, stitute part of this specification, and repre formed in the center of the lower face of the sent, in longitudinally - movable and rotary bolt 8.

Near cordance with my invention, showing the bolt its forward end the extractor is formed with closed and locked and the extractor in readi an extracting-hook 10, adapted to enter a neSS to engage with the spent shell upon the notch 11, formed beneath the cartridge-re initial movement of the bolt in starting rear ceiving chamber 5" in the barrel 5 to permit ward; Fig. 2, a similar view with the bolt un the said hook 10 to engage with the forward locked and drawn back into position for pick face of the flange or rim of the shell. ing up and pulling back the extractor, the for The extreme forward end of the extractor ward end of which has been released by the bolt, consists of a releasing-finger 12, entering and thus permitted to engage with the spent when the gun is closed a notch 13 in the barrel shell: Fig. 3, a similar view with the bolt and 5 and when the gun is open a notch 14 there extractor drawn to the limit of their rearward in, these notches being separated by a shoulder positions, the extractor being shown in the 15, which for convenience I shall call a 're 75 position which it takes after the ejection of leasing-shoulder,’ for the reason that when the spent shell; Fig. 4, a similar view with the gun is opened the finger 12 drops off the 3O the bolt pushed forward to the point at which shoulder 15 from the notch 13 into the notch its beveled forward end engages with the de 14 and allows the forward end of the extractor pressing-cam of the extractor for depressing to spring upward for the ejection of the the same, so that the releasing-finger thereof spent shell, which at this time has been fully will clear the releasing-shoulder formed in the extracted from the chamber 5" in the barrel 35 gun-barrel at a point directly below the car 5.

It will be seen by reference to Fig. 1 that My invention relates to an improvement in when the bolt is moved into its closed and firearms, with particular reference to extrac locked position its bevel 17, engaging with tors therefor, the object being to provide sim the cam 16, depresses the forward end of the ple, durable, and effective means for extract extractor, which is thus placed under spring 45 ing and ejecting the spent shells. tension, with its nose 10 located slightly below With these ends in view my invention con and slightly forward of the rim or flange of sists in certain details of construction and the cartridge 9.
