EJECTING MECHANISM OF SPORTING GUNS OR RIFLES.

SPECIFICATION forming part of Letters Patent N 0. 423,825, dated March 18, 1890. Application filed June 11, 1889. Serial No. 313,854- (No model.) Patented in England January 27, 1887, No. 1,281,

.To all whom it may concern:

Be itknown that 1, JAMES WVILLIAM SMALL- MAN, a subject of the Queen of Great Britain and Ireland, residing at Nuneaton, in the 5 county of lVarwick, and Brixton, in the county of Surrey, England, have invented a new and useful Improvement relating to the Ejecting Mechanism of Sporting Guns and Rifles, (for which I have obtained a patent in Great Britain, No.1,281, bearing date January 27, 1887,)

of which the following is a specification.

This invention relates to self-ejecting hammerless sporting guns and rifles and it consists in the means employed for releasing at the proper time the ejecting mechanism while the gun or rifle is being opened. In guns of this class it is necessary to release the ejecting mechanism appertaining to each barrel independently, in order that empty cartridge- 0 cases only maybe thrown out, and, moreover,

this end should be accomplished without increasing the normal amount of work to be performed by the tumblers, thus enabling lighter mainsprings to be used than would 5 otherwise be permissible. Hitherto it has been considered requisite to employ a separate slide in each lock actuated by the mainspring either directly or through the tumbler, and retained in the operative or the inoperao tive position by a friction-spring and roller or equivalent means. Such unnecessary complication renders the gun liable to derangement, besides adding to the cost of manufacture. In addition, a mainspring in each lock 5 heavy enough to overcome the friction of the retaining device and move the slide, as well as cause the tumbler to strike the cap with sufficient force, must. under such circumstances be employed, thus making the gun o more difficult to open than when a lighter mainspring which has only the tumbler to actuate is used. According to the present invention the fall of the tumbler is not impeded. The lock work, moreover, only contains the same number of individual parts as would be required in a gun having no ejecting mechanism.

In the accompanying drawings, which serve to illustrate one method of carrying out my invention, Figure 1 represents, partly in seotion and partly in side elevation, that portion of a hammerless gun to which the present improvement relates, the right-hand lock being exposed and the tumbler being cocked, and the means for releasing the ejecting mechanism in the inoperative position. Fig. 2 is a similar view, the tumbler'being down and the means for releasing the ejecting mechanism in the path of the ejector-sear tail. Figs. 3 and 4 represent a mainspring in side eleva tion and plan, respectively, which is adapted to serve the double purpose of a mainspring and an ejector-sear stop.

The ejecting mechanism, which comprises the rod to, the spring a, and the ejector-sear b, is in duplicate, in order that each half 0 or c of the split extractor may be actuated independently. Both halves of the split extractor are forced out in unison. to the usual extent each time the gun is opened by the extractor-post d, carried by the fore-end 6. Then if one or both of the barrels has or have been fired one or both of the ejector-sears is or are lifted, the empty cartridge case or cases being thereupon ejected from the gun.

For liberating each ejecting mechanism the mainspring fin each lock is formed with a solid projection f, which acts as an ejectorsear stop. lVhen the mainspring is in the backward position, as in Fig. 1, the stop f is out of the path of the ejector-sear tail b, and is therefore inoperative; but when the lock is liberated, as in Fig. 2, the stop is brought farther forward than is necessary for releasing the ejecting mechanism. Then while the bar- 8 5 rels are falling the stop f is gradually moved from under the ejector-sear tail 1), and at the same time the latter gradually approaches the stop until just before the sear g snaps into the tumbler-bent the stop and the ejector-sear o tail arrive in contact with each other and the ejecting mechanism is liberated.

It is obvious the stop f on the mainspring f may be employed for releasing any kind of ejecting mechanism which is mounted in the 9 5 fore end and retained in the active position by a scar. The particular ejecting mechanism shown. in the drawings is merely given cock, the combination, With an ejector-sear stop formed on the sliding mainspring, of an ejector-sear turning about a pivot carried by the fore end and engaging with ejecting mechanism also carried by the fore-end, substantially as set forth.

JAMES W. SMALLMAN.
