JOHN FRICK, OF LARAMIE, VYOMING TERRITORY.

GUN-LOCK.

SPECIFICATION forming part of Letters Patent No. 426,004, dated April 22, 1890. Application filed January 29, 1890. Serial No. 338,477. (No model.)

ers, in which the hammer'is caused to rebound after it has caused explosion; and the invention consists in the construction of the tumbler, in combination with the mainspring, the slotted link uniting it to the tumbler and the abutment to arrest the mainspring and link, so that after the hammer has been thrown down it will be free to rebound back to halfcock without danger of disconnecting the link from the tumbler or from the spring.

In the drawings, Figure 1 is an inside view of the gun-lock, showing the hammer in its farthest forward position. Fig. 2 is an inside view of the same, showing the hammer retained at half-cock. Fig. 3 is an inside view of the same with the hammer at full-cock, and Fig. 4 is a perspective view of the tumbler and its link detached.

In said drawings, A represents the 1ockplate, and A the inner frame for supporting I the several moving parts; 13, the hammer; O,

the mainspring; D, the tumbler; E, the connecting-link between tumbler and mainspring; F, the sear; G, the sear-spring.

Over the freer end of the mainspring and proj ecting inwardly from the lock-plate A is an abutment a, against which the-mainspring brings up just before the hammer may strike the percussion-cap or firing-pin. The under face of said abutment is of such size as to also cover the journal-pin e that projects laterally from the sides of the link and engage with the hook on the end of the mainspring and prevents said link from becoming disconnected from said spring; but to permit the tumbler to be rocked to the position shown in Fig. 1 said tumbler is longitudinally slotted at cl to receive the link E, and the pin d that connects the link to the tumbler passes through a slot e in said link, and there is thus no danger of disconnection between the mainspring and the tumbler.

Having now fully described my invention,,

I claim The combination of a gun-lock plate, the mainspring, the hammer, its tumbler longitudinally grooved, a link provided with a j ournal-pin in engagement with the mainspring' JOHN FRICK.
