In all guns of this description there is necessarily a lateral discharge between the receiver and the barrel, and this lateral discharge may endanger the ignition of the powder in the loaded chambers not in contact with the barrel; but the ignited matter, by coming into contact with the beveled edge as it crosses said chamber, is effectually reflected off, and does not enter them. The beveling of the end of the barrel is not a thing of importance, it being intended merely to prevent its scraping or cutting the ball in its passage from the chamber.

F is the hammer carrying the hand or pawl S, which operates on the ratchet-wheel, which wheel and hand are arranged in the same way with the same parts in the rifle; but the hand is as here represented on the reverse side. The bolt which holds the receiver is, however, differently constructed to enable it to act in the space which it must occupy.

The lateral springing of the cam-piece l is necessary to admit of its passing by the projection o of the bolt when the hammer is made to strike upon a percussion-cap. To enable the spring-cam to pass the bolt E, the lower end of it, n, is made wedge-shaped, diminishing to a point or edge at its extremity, and as it is made to spring laterally it is received into a recess in the hammer as the latter passes the bolt in making the discharge.
