_CARTRIDGE-STOF’ FOR MAGAZINE-GUNS.

SPECIFICATION forming part of Letters Patent Noo 455,514, dated July '7, 1891.

Application filed November 8, 1890. Serial No. 370.830. (No model.)

5 next cartridge'in its depressed position af ter the uppermost cartridge is removed by the advancing bolt ct and pushed into the barrelB. The bolt ct, having pushed the car tridge into the barrel, is now turned to the right by means of its handle ct’ into its closed position. During this turning motion the top end n3 of the tumbler n enters from the lon gitudinal groove s into a short cross-groove s’ inl the bolt ct until it is struck by an in

15 terruption or tooth t .of this cross-groove s', which tooth t, as the bolt turns moves the top end or” of the tumbler to the left again, caus ing the various proceedings before described as the tumbler is tilted on its pivot, thusper

zo mitting the uppermost cart-ridge in the mag azine to be released from under the edge rrr’ and to rise to the position shown in Fig. 2. Before the bolt a has finished turning the tooth t has passed the top end n3 of the tum

z 5 bler, which now returns to its normal position . by reason of its end n3 entering an indenta tion or hole s2 onthe bolt a when' the latter reaches its closed position,which indentation s’ is practically a continuation of the cross

go groove s2. After the discharge of the gun and in turningthe bolt a to the left for open ing the breech the tootht moves the tumbler ’fr to the right, which, having passed the tooth t, returns int-o its normal position. When the

3 5 bolt a has finished its back-stroke, the upper­' most cartridge will rise and present itself to the returning action of the bolt a.. W'henever the bolt a is pulled back before it has been fully closed, the next cartridge is prevented

4o from presenting itself to the action of the bolt a,since until the tumbler is tilted by turning the b_olt to the closed position the detent in', restraining the cartridge, is not displaced; but if the bolt is once normally closed and

45 then drawn back the uppermost'cartridge of the magazine will always appear in its nor mal position, its detent having been displaced by the closing operation. s . The application of my invention to the bolt

50 guns at present in use does not require an es-v sential alteration of them. The grooves s s’ s2 can be milled in the bolt a without other changes of the lock mechanism, and the mounting of the tumbler n, as well as the

5 5 small alteration of the side sheets of the maga zine m, will in no wayinterfere with the pres ent construction.

It will be understood that instead of using a portion of the side sheet of the magazine m

6o for the spring-edge m’ a separate spring prop erly shaped and fastened to the frame of the magazine m may be employed; also, that my

455,514

invention may be variously modified and may be applied lto various styles of guns without departing from its essential features, and that I do not limit myself to the construction herein « set forth, which is the preferred form of my in vention. ­

After having fully described and ascer tained the nature of my invention and in whatvmanner the same is to be performed, what I claim as new, and desire to secure by Letters Patent, is, in bolt-guns, the following defined novel features and combinations, sub stantially as hereinbefore set forth, namely:

l. In a breech-loading bolt-gun, the combi nation, with the bolt and the cartridge-maga zine opening below the bolt, of a detentpro j ecting into the path. of the rising cartridges and constructed to prevent the cartridge within the magazine from rising into position for engagement with the bolt, and means con structed to act on said detent and to engage with said bolt and to be operated by the move ment of the bolt to the closed position, and thereby to automatically disengage said de tent. , ~

_2. In a breech-loading bolt-gun, the combi nation, with the bolt and the Acartridge-maga zine, of a detent located adjacent to the magazine and constructed to project into the pat-h of the rising cartridges and to prevent the top cartridge within the magazine from ris ing into position forI engagement with the bolt, and means for automatically disengag ing said detent, consisting of -a tumbler en gaging said bolt andY constructed to be oper

having the grooves s s’ s2 and the tooth t, and the magazine m, having the projecting spring m’ far enough below its top to hold the car trid ge from engagement' with the bolt, in com bination »with means for disengaging said spring m', and consisting of a tumbler enter ing said groove in the bolt and operated by _the rotation of the latter.
