To all whom it may concern.-

Beit known that I, BERNARD FAsoLD'r, of the city and .county of Albany, and VState of .New York, have invented certain .new and usefnl Improvements on FireArms,-of which the following is a full ,and exact description, i

reference being had to the accompanyingdrawlng, making a part of this specih'cation, in which- .r

Figure 1 is a :longitudinal section of the' breech and lock-work-of a gun embracing my improvements, showing the breech-piece and and the droppingof-the breech-piece, so as to leave the gun in condition for reloading.;

As shown in the drawing, A is the breech f of the'gun; B, the frame-work for -connecting` the barrel to the stock, as shown,'(one of its side -plates is removed for the purpose of exhibitin g the construction, more clearly C, :the breech-piece, hinged to the frame-work Bby the pin c1, and provided with a mortise, which forms an opening, in which the hammer works."

In its forward end-a chamber, c2, is made, which coincides with the boreof the barrel of the gun, and in'which the head of the plunger D is tted to slide freely. This plunger has arod', d1, which passes through the plate c3, and' terminates in a button-head outside of-saidplate.

A. projection, d2, dependent from the head 1),.

slides in a slot cut in the lower side ofthe chamber c2, and enga-ges with the shoulder of the sliding pin E. A coiled spring, d3, sur.- ronnds the rod d1, and, by exerting its force between the plate c3 and head D, drives the head outward, so that its face will'be ush with the end of the breechfpicce. A firingpin, d, passes through the axis of the plunger, and projects therefrom sufficiently to receive the stroke of the' hammer, whereby it is driven with sufficient force against the cartridge to explode its fulminate.

- F. the hammer of the lock,working in the mortise'of the breech-piecek C, and pi'voted to `the frame-workB by the pin f1. 0n its'front edge a cani-'shaped projection, f2, is formed, against which the sliding pin E bears, as hereshoulder, f3, is made,again'st which the mainspring G presses. On cachot' its sides it is cartridge vcan occur.

A When thebreech-pieceC is raised,the projecting point e ofthe sliding. pin E bearsagainst the under side of the breech of the barrel, and prevents it from being carried above its correct position. Bearing beneath the shoulders ofthe cams f?, and secured tothe pivoted end of the breech-piece C, the springs operate to set in a'cocked position, as shown in Fig. 2.y

in the hammer. F.

H, the trigger, pivoted to the frame-work B by thepin h. It has a point, h2, which 4catches in the notch fain the hammer, forfthe purpose ,of holding the hammeriu a cocked position. vIt is also provided with a hook, h3, as shown in-the drawing, which engages with the springcatch f5, for the purpose hereinafter described. I, a spring secured to the frame-work B, which presses upon the shoulder h4 ofthe trigger, for holding the point hz securely in the notch f6 ofthe hammer.

compound in the center of its base.

To insert the cartridge, the breech-piece C is depressed, as .shown in Fig. 2, bycocking the hammer of the gun, either by hand or iu the manner hereinafter described, thereby giving free access to the breech of the barrel for the insertion of the cartridge.

The firing is ei'ected by pulling the trigger f' of the hammer F, whereupon the main- -spring G forces the hammer forward, which, by its cams f, raises the breech-piece() into its position, as shown 4in Fig. 1, before the inafter described. 0n its posterior edge a provided with cams f, which bear against' `the side'bars of the breech-piece'. C, for the i purpose .of raising it, by apositive motion, to itstrne position. before any explosion of the depress the breech-piece. whenv the hammer is i f5, a spring-catch, work-in g in a'reces's formed The loading of vtheL'gun is effected by car-- tridges. Preferably I use those havin gmetal-4 lic shells or cases, and having the fulminating H, thereby releasing its point 1.? from the notch ha miner strikes the tiring-pin di to explode the cartridge. -At thev instant the explosin occurs, the force of the discharge, reacting against the'base of the shell of 'the cartridge,

As this operation is effected instantaneously, whi le the-pressure of the linger is still retain ed upon th'etrigger H, some provision is requiredfor catching' and; retaining the hammer as it is thrown backward. This I accomplish by means ot the spring-catch f,which engages pressedposition as long as the explosive force.

of the 'powderis reacting upon the shell of the cartridge. Thereby absolute ,security isv provided against.A accident or `injury by -the cartridge being discharged rearward. j

When the; shellof the cartridge is relieved from the force of the y explosion, the springd3 forces the plunger D- forward, so asl to restore theshell'in'thebreech ofthe barrel, whereupon the springs 4c" force the breech-piece O into its depressed positiomas shown in Fig. 2,'

wllen'thel shell can be drawn fromthe'- barrel and a newcartridge inserted, leaving the gun in condition -for another discharge.

Among the many-advantages arising from;

my improvement is the relievingof the shoulder of' the person'us'ingrmy gun from the shock Ausually caused by the recoil ofthe `gnnwhen discharged, which -in this gun is ent` ely expended upon the springs d and G. f

I claim as my invention- 1. The hinged' breech-piece C, provided with a chamber, c, incombination with the plunger D and spring d*,as andt'or the purpose specified.

2. The combination of the hinged. breech- 'piece C, provided with a chamber, o, with the plunger D and sliding pin E, as and -for the purpose specified. e

8'. The hinged breech-piece C, provided with a mortise, as hereindescribed, in combinationy with' the hammer E, having its pivotal center' xed-to the frame' work B, as and for the purpose specified.

4. Thecombi'nation-ofthe plunger D and sliding pin E, with [the hammer F, when arranged to co-opcrate in' the manner as an for the purpose herein specified.

5. The-hammer F, provided with a spring-j catch, f5, vincombination with the trigger H, having a hook, h3, as and for the purpose specitied.

6. The hinged breech-piece '0, pivoted to the "frame-work B. by the pin c1, in combination with the hammer F,having the cams f, for raisingv the breech-piece automatically when the hammerl is thrown forward by the main spring G, in the manner and for the purpose herein specified.

.7. The combination of--the hinged breechpiece C, provided with a chamber, c', plunger D, and sliding pin E, with the hammerF, having camsf and springs c, when cooperating as herein described, to et'ect the` 'docking of the hammer F, and depressing the breechpiece C, as hereinspecited.l

8. Thecombination of the plunger D and.

.firing-pindA with the hammer F," asand for the purpose specified. -v
