Toa/ZZ whom it may concerlm' -Be it-known that I, FRANcIs CLARK,ofA u Y burn, inthe ccuntyof Worcester and/State of Massachusetts, have invented certain new vand useful Improvements in Breech-Loadin AFire- Arms; Yand -I do hereby declare that the following is a full, clear, andexact'description of tileponstruction and operation of the same,` referencebeing had to the accompanying drawings, in which-i Figure^`-1represents a perspective view of said breech-loading fire-arm I+ `i`gs.`v 2 and 3 rep -f 'resent longitudinal vertical sections through the same.'

My. invention: consists in constructing the .cartridge-extractor' of a breech-loading gun in such a, manner that'itfcan be operated either directlyfby the'hammer or by meansA of a trig- .ger or arrnin'i'ront of the breech. l

which I securce 'the of the gun. Toi enableothers skilledinthe art to make and use m-yinventim will proceed to 4describe -its` construction andoperation.

-f The barrel A o'f mybreech-loading arm issecured to the breechpiece -B' by means ofscrew or in any well-known manner.. The breechblcck, which opens and closes the breech, and which is no t shown onj the drawings,`is of the construction as shown and described in my Letters Patentdated the 19th" day offJulygg 1864. l The said'breechfblcck in'this present case is`secured to the cylinde1' O,- which-is set and turns upo'nthe cylindrical breech-piece'B.

breechpiece to the stock i The latter is secu-red tothe ystock D of thefire-v arm by-mean's of a pin, E, 4which entersa sitable cavity within `the saidl stock, and the two are secured toge'ther by means of a' pin or' wedge, d, andthey thus constitute avery sim ple and firm connection, by which the arm can be' taken ap rt. and put together with great facility.A F 4`represents my' cartridge-extractor for withdrawing the 'metal cartridge case Afrom the ree'ch of the gun after the charge has been .fired -lIt consists of' a rod, b, which can slide within a suitable groove in the'breech-piece, B, and which is provided with a toe, c, which,`

.when at rest, ts in a' recess, d, ofthe breech and in front of the cartridge-rim, as represented in Fig, 2. ,The rod g of the cartridge-extractor 'extends toward the muzzleoi thegun, and is the*peculiarmannerby A leasedv from the pin'2, and when thus released The rear end ofthe cartridgege'xtractor ispro# vided with ahook-shaped projectiomm, against which the pin 2 of thehammer G acts when 'said hammer is cocked.

In Fig; 2 the'hammer. is shown full-cocked,

and in that position the cartridge is in the and the piece is ready to be fired.

'bi-"eefh,v The charge being iired, the pin 2 on the hammer comes in frontof the hook m, and-in cooking Vthe hammer the rod b and the cartridge-extractor are pulled to the rear, 3, and the cartridge-caseis consequently with- .drawn from thebreech. v The motion of the hammer Gand rod b continue untilthe pin 3 .of the hammer commences t0 .press upon vlthe hook m, 'when.'-thelatter is depressed andrethe spring h' instantaneously causes the rod g and the cartridgeextractor to Jreturn -to the position represented in Eig. 2. Byproviding the .pin 3 with ascrew-thread lI am enabled 'to adjust its position with great accuracy, so, to cause `it to press upon the hook mfwheu the'latter has'been withdrawn to. a certain extent, and thus the point at'which 'the cartridge-extractor is to be sprung; back with the greatest accuracy; The several parts :described are so arranged that the' hammer --will not catch the extractor whenI letdown tohaIf-cock; and I adj ust'the Vpin 3 to' such a-position that the hammer will release the hook mbefore it isfullfcocked.

v'Ihis cartridge-extractor can a-lso'be oper 'ated by hand and independently of the'ha'lin- `mer G by el'ongating the 'rod g, so as to make vit extend beyond the breech-piece'B, and when thus constructedit can be pushed to therear by the pressure of the nger', ,and it operates vinnamemanner as when actuated'bythe hamA mer, as above described.

The cylinder G may be provid-ed with an in? ternal screw-thread to work upon a male screwthread cut on the cylindrical part ofthe'breechpiece'B, whereby thev-breech-block is moved back 'as well `as laterally when it is opened, the object being to make a close t at the'rear of thecartridge when the .breech-,block is closed; also to make it open easily.

The hammer can be made with: a notch to .arm g, so'thet it can be operated either from' the front by means of said arm'or from the rearby means of the hammer, substantially'as herein described. l

3. The lapplication to the hammer of vthe regulating-serew, in combination with the cartridge-extractor, substantially as and for the purposes described.
