Presuming that the gunhas been fired, the action is as follows :—On open-ing the barrels, the tumblers are raised by theirturned-in extremities bearing on the additionalstud of the cocking swivel ; when raised nearly tofull cock they slip past this stud, and fall sharplyon the lower arms of the ejecting levers, andthe extractors, already withdrawn by the usual And How to Use It. 31. bfi O O bJOen o BS Q GO C< 32 The Breech-Loader, extracting mechanism to the ordinary extent, areviolently propelled to their full extent by the forceof the blow, and the empty cases are flipped one cartridge only be fired, the other lock re-maining at cock does not engage with the cockingswivel or put the ejecting mechanism in motion ;consequently, unfired cartridges are withdrawn tothe ordinary extent in the usual manner. Theavailable power for ejecting the fired case is that ofthe mainspring falling; the mechanism effects theejection perfectly. This gun requires most careful adjustment, andalthough the parts are few, simple, and very strong,to ensure their perfect working the utmost pre-cision is necessary in centreing, shaping, and ad-justing the various limbs. The gun can be madeby highly-skilled workmen only, and must neces-sarily be of the best quality throughout. Another form of ejector is that in which aseparate lock mechanism
