' A horizontal plunger rod is provided in the hole or spring chamber 3 inthe lock casing 5, and 44 is a crosshead bent to avoid the firing pins 27 and 28' and 451s a f' spiral spring adapted tohold said rod nornially in its forward position. VAt right anerably integral therewith, a lever 46 which fis adapted to normally engage Vsaid vertical gles to said plunger rod 43'is provided, prefslot 4. `The said leverwhen operated is turned outv of engagementwith the slot 4 and'pulled rearwardly into the slot 3 there-` by carrying the vrod 43 and the head 44 rearward. -The breech block 19 that isV engaged "(as shown in the drawings) vwith saidhead 44 by thejhook or the bar 435jwillbe carried F out of the chamber or casing 17.
