Description

JOSEPH C. DANE, OF LA GROSSE, VVISOONSIN.

Specification forming part of Letters Patent No. Ei, dated January 20, 1874; application led January 10, 1873.

To Il whom it muy concern:

13e it known that I, JOSEPH G. DANE, of the city and county ot' La Crosse and State of Wisconsin, have invented a new and Improved lrcech-Loading Fire-Arm; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming a part ot' this specitieation, in Whichlfgure 1 is a partly sectional side elevation of a breech-loader provided with my improved tiring-pin or strikerl7 t Fig. 2 shows a longitudinal section of the strikerdetached from the lire-arm.

The object ot' my invention is to provide a tiring-piu er striker for drop breech-loaders which shall occupy less space in the recoilshiehl than those heretofore employed in guns el' the needle pattern, and yet have the necessary weight to act eiciently on the cartridge by momentum. This I accomplish by providin the striker with an annular flange projectiu downward around the pin and over or inclosing the spiral recoil-spring. Thus ample space is provided for the latter, so that it may he ot' a length necessary to its due elasticity, while the liange acts also as a stop to arrest the movement of the striker toward the eartridge at the proper moment, the proportions and arrangement of the device being such that the pin is always within the recoil-shield, eX- cept at the instant ot' impact on the cartridge, securing thus the advantage incident to the ordinary combination of tiring-pin and recoilhammcr, as hereinafter described. I

A center-tire cartridge-shell, G E, is shown inserted in the breech of the dropbarreh The recoil-shield f is provided with an oblique recess to receive the striker a, and the same is confined therein bythe nipple B, which screws into its place, as shown. The striker is made in one piece, and with a shoulder near its upper end, which7 when the hammer d is raised, is in contact with the inner end of the nipple, and has an annular recess, c, formed in its base or lower end around the pin e, for the purpose of receiving the spiral spring O. The correspondingly-annular flange/i serves as a stop for the striker when acted on by the hammer, and also gives it the weight necessary to im-l part to it the momentum requisite to a proper ettect upon the cartridge. Without the liange the striker would require to be made longer or thicker, or both, thus taking up an undue amount of space in the recoil-shield, or else the spring O would require to be made shorter and the annular cavity jlled up, thus unduly lessenin g the elasticity'of the spring and destroying its proper action.

Ihat I claim is- The striker a, provided with a shouldered head and having an annular tlan ge, c', and corresponding recess c for the recoil-spring, said flange extending toward the point of the tiring-pin c to act as a stop, all as shown and described. I

JOSEPH C. DANE.
