BREECH-LOADING GUN.

SPECIFICATION forming pa i 't of Letters Patent No. 452,699, dated May 19, 1891.

Application filed April 24, 1890. Serial No. 349,332- (No model.)

To all whom, it may concern.-

Be it known that I, \VILLIAM Rosa FrNoH, a citizen of the United States of America, residing at Eureka, in the county of Humboldt and State of California, have invented certain new and useful Improvements in Fire-Arms, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide an improved fire-arm wherein the triggerguard lever is adapted to effect the cooking of the hammer; and it consists in the detailed construction and combination of the parts, as will appear from the following description and accompanying drawings, in which- Figure 1 is a side elevation of my improved fire-arm, the inclosing casing being removed. Fig.2 is a similar View showing the breech open. Fig. 3 is a front elevation of the slide and the trigger-guard. Fig. at is an opposite elevation thereof, and Fig. 5 is a detail perspective view of the shel9-ejector.

In carrying out my invention I employ, as usual, the breech portionA of a fire-arm, having secured to it the inner end of the barrel a.

f is the trigger, hung in the case 0 and engaging the spring-pressed end of the usual pawl, its lower end depending from said case for the convenient action of the finger.

0 is the trigger-guard lever, pivoted at its extreme forward end, as at g, in the lower forward end of the breech-case A, and having an offset or stop g inward therefrom, resting against the under side of the lock-case c, a similar offset or stop g being formed upon. its upper extreme rear end, resting or bearing against the under side of said breech-case. The rear end of the lever has a loop 0 for its convenient manipulation, while its forward end rests again st a powerful spring 72, secured to the under side of the barrel a. Also, at the forward end of the lever O, and a short distance rearward from its pivot, is a recessed cam shoulder or lug 2', which is connected by a link j to the breech-block or slide 1), arranged to slide vertically 1n an opening L in the breech-case A, between the lnner end of the barrel 0. and the hammer B. The cam shoulder or lug 41 engages a correspondiugrecess e" in the lower forward end of the lock case 0 to provide for effecting the cooking action of the hammer, as will more fully be seen further on.

The breech-block or slide, the cam shoulder or lug, and the link are all adapted to stand in alignment when the lever O is resting against the under side of the breechblock or slide, the lower end of the breechblock or slide being bifurcated and having the branches orarms c 0 thus formed, guided or moving one in a groove or recess Z in one side wall of the opening 7.: and the other against the rear wall of an extended recess or chamber Z in the opposite side wall of said opening for the cartridge-shell ejector or extractor, the inner surface of said rear wall standing in alignment with the inner surface of the rear wall of the groove or recess Z. Thus it will be seen that when the rear end of the lever C is moved outward the link j will move the breeclrblock or slide also outwardly in its action.

The breech-block or slide is provided with a rearwardly-projecting guide-rib D, engaging a corresponding recess in the upper rear Wall of the opening 7t, and with an inward and downward inclined beveled surface just above the firing-pin, carried by said breechblock or slide to permit it to readily pass the forward edge of the hammer 13 as the breechblock slide is moved downward.

The upward movement of the forward end of the pivotedlock-case isllimited, as the slide D is returned by the forwardly-projecting portions or lugs n at the upper side of the recess 2' of said case, having contact with the offset shoulders 2' upon the side Walls of the lock-case opening, the upper inclined edges of which shoulders form abutments for opposite edges of said lock-case when the latter is in its normal position. These shoulders have a uniting partition e between them, the upper edge of which forms the hammer-stop i E is the cartridge-shell extractor or ejector, which is hung or pivoted in its chamber or recess Z upon the pivot g of the lever C, and has its upper end let into a recess 0, through which its tooth 19 engages the flange of the cartridge-shell, while its lower end is provided with an arm E, which is engaged bya shoulder (1 on one side of the breech-block or slide D near its lower end, which actuates the ejector or extractor after the upper end of said slide has been lowered out of the way to efiect the extraction or removal of said shell.

It will be observed that when it is desired to cock the hammer the lever O is moved away from the breech-case, effecting the outward movement of the breech-block or slide D, which in turn, by means of the lugs 92 and the shoulders 1?, effects the lowering of the inner or forward end of the lock-case. Thus the hammer, by its forward or free end remaining in contact with its stop "6, will be prevented from moving with the lock-case. Consequently the movement of the. latter as its free end is depressed by the lever C will effect the cocking of the hammer. Also, when the lever has about reached the end of its maximum onward movement the ejector or extractor E will be moved outward through the action of the shoulder q and arm E, as before set forth, and thus extract or eject the cartridge-shell, a cut-away portion, as at a", at the upper end of that side of said slide providing for the maximum movement of said extractor.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a firearm, the combination, with the hammer and its pivoted lock-case, of the trigger-guard lever pivoted to the breechcase and provided with a cam-lug a short distance from its pivot, the breech-block or slide having a guide-rib provided just above the firing-pin with an inwardly and downwardly beveled surface, said cam-lug of said lever engaging a recess in the inner end of said lock-case, substantially as shown and described.

2. In a firearm, the combination of the breech-block or slide, its actuating-lever, the

cartridge-shell extractor or ejector connected to the pivot of said lever and adapted to engage the shell in the barrel, said ejector having near one end an arm engaged by a shoulder on said slide or block, the hammer and its pivoted lock-case, the trigger-guard lever pivoted to the breech-case and provided with a cam-lug a short distance from its pivot, said breech-block or slide having a guide-rib just above the firing-pin, having an inwardly and downwardly beveled surface, and said cam-lug engaging a recess in the inner end of said lock-case, substantially as set forth.

3. In a fire-arm, the combination, with the hammer and its pivoted lock and the breechcase, of the trigger-guard lever pivoted to the latter, and the bifurcated orbranched breechblock or slide arranged to slide vertically in said case, said lever extending through the bifurcated or branched portion of said slide or block and having acam-lug engaging a recess in the free end of the look-case, and said breech-case having a stop for'the forward end of said hammer, substantially as shown and described.

4. In a fire-arm, the breech-block or slide having the strip or guides on its rear face, the upper one of which is beveled on its lower face to permit it to readily pass the forward edge of the hammer as the breech-block is moved downward, said block or slide being connected to the pivoted trigger-guard or breech-block bolt by means of a link, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
