TheV operation of c urgin venton is as'follows Suppose there are cartridges lin all the-chain bers, and one has heemcxplodedr fWhenthe hammer is., cockedvtthe-icylinder `isvrotated bringing the next cartridgefintopositom-and the extractor h (whichs'isin the 'posticnshown in Fig. l) strikes againsttheprojectiongwand is tilted forward int-(inthe Y positionfshown in Fig. 1V, and is helde'ien fthatfposition by the spring. b, which pressestttragain'stthelower side ofthe projection f on the extractor,

Asthe hammer moves forward in exploding the next cartridge the point ot the extractor, being held by the spring in the proper'post inthe movement of :the hammer backward, -v

tion, is guided into and enters the small groove i the fchamber. thrown or tilted backward, thelower end of' `u ntil the latter pressesagainst the-opposite strikingv against the projection 'to tilt it: fory ward again, as before.

Fig. LIII, or be discharged withoutdrawing the shells, by shutting the gate, as shown in-` the extractor may be swinging" behind the hammer pivot in the same direction as the hammer, and operated by it, as shown clearly 'in Fig. 1V,'in wbichn is a'c'rooked piece 'swinging behind the'ham-face ofthe cylinder, a gate,-F, pivotd At0 the frame,-aga rins'tl the .rear face-of which, when shut, the end of the extractor strikes, and kis thereby prevented from entering the `said 7" mer-pvot,andhung upon v the trigger-pivot position as upon the hammer in Fig. '1, as

from the chamber, when "the protuberance e on the front edge ofthe extractorstrikes against, the part c of the frame, which throws 'the pointof the extractor quickly backward, giving the' said extractor a sudden accelerated movement backward, and ejecting the shell entirely from When the extractor is thus the 'projection ftilts-over upon the spring b sldevbf the said projection, and the hammer is then moved back, as before, the extractor 'A gate, F, is pivoted at sI to the frame or side plate-in rear ot' the;cylindcrfwhich gate is provided with a plane projection, o, which,

headand in front of vthe extractor, sol that, when shut, the gate prevents the point of the the point of the 4'extractor striking the sai-d same as if The arm may thusbe discharged, and the shells extractedat each discharge, by'opening the gate F, as shown in dottedlines in black lines inthe same figure. Instead-of being .pivoted' tohthe hammer, pivoted tonother piece,

I), said piece having a recess, t', which engages with a pin, in the-.hammer. In this case the spring'b maybe arranged on the. frame, inside, or on theA side plate, but in the same shown in dotted lines in Fig. IV, so that what'- ever the extractor is 'attached or pivotedto,

as it vibrates back and forward, itis movements and operations are precisely alike.

It willbe seen that when the hammer is at riesameI half-cock the 'ejector isbeldin a position tltv ed back by the'slning, so that the point ofthe ejector is ou't ot' the way when loading the arm, and is held-in a position tilted forward,

ready for extracting the shell whenthe hammer is at 'full cock, the extractor being tilted "or thrown forward bycontact with the projccl.
