receptacles are received and revolve.

Figs. 25 and 26 represent a top view and a side view of a part of an improved bullet-mold, which I describe without intending to make any claim thereto, but merely for the purpose of showing the whole of the apparatus employed in a complete and connected series. a a are the two handles of the mold, and b the handle of the knife by which the sprue is cut off. c is one-half of the mold, of which d d is the hinge-joint. e is a plate of steel, through which there is a hole, f, for pouring in the lead, the lower edges of which constitute a knife by which the sprue is cut off and the ball left perfect. This knife turns on the joint-pin g.

Having thus fully described the manner in which I construct and use my improved fire-arms, and the respective articles of apparatus appertaining thereto, it has been necessary in so doing to mention many parts which I do not claim as new, the same being similar to what has been before used and patented by me, or which are common property. I do hereby declare, therefore, that I limit my claim to the following particulars.

I claim—

1. The making of a groove or channel on the arbor, as represented at b, Fig. 2, for the purpose of conducting off the smoke from the lateral discharge, and thus preserving the arbor clean within the receiver, and the tube by which the barrel is connected.

2. The particular manner of forming and governing the key by which the barrel is attached to the stock by making the same with grooves in which the heads of overlapping screw-heads are received, and with a tempering-screw to check and regulate its action as a wedge, as set forth.

3. The making the aperture through the tubes or nipples (which receive the percussion-caps) conical or funnel-shaped, for the purpose of freely admitting the fire from the percussion-cap and concentrating it as it enters the chamber.

4. The manner of arranging the bolt E of the rifle and its spring cam l n for locking and unlocking the receiver, the same being constructed and operating as herein described.

5. The manner of constructing and arranging the bolt E and its spring-cam, operated upon by the cam or projecting piece z under that modification thereof adopted in the pistol, and herein fully made known.

6. The improved manner of arranging the ratchet-wheel and band, as set forth, by which the hinge-joint to allow of the lateral motion of this band, as described by me in my former patent, is dispensed with in consequence of the placing of the ratchet-teeth on the face instead of on the side of the wheel, and operating the same in the manner described, as applied to the rifle and to the pistol.

7. The combination of the lever with its rammer for forcing the balls into the chambers of the receiver, as described.

8. In the improved cap-primer, the making thereof with a spiral groove to receive the caps, and with the sliding arm acted upon by the spiral spring elongating itself and forcing the percussion-caps forward in the manner set forth.

9. The manner of constructing and arranging the respective parts of the magazines for powder and balls, in the flask, by means of which the powder and the balls are in turn supplied to all the chambers in the receiver at the same time, the whole being made with the chambered receptacles and other parts, as set forth.
