Horse′shoe nail-ma-chine′.

One in which rods of iron are shaped into nails for the purpose stated.

In one form of this machine, the nail-rod is fed downward through a heating furnace in front of a stationary anvil by means of a cam geared to make one movement. As each finished nail is cut off at right angles to the face of this anvil, two sliding hammers, having faces of the contour the reverse of the sides of the finished nail, are forced against the sides of the blank simultaneously by means of [1130] springs; a third hammer works perpendicularly to the face of the anvil, alternately with the other two, by which the nail is forged. When the nail has been sufficiently hammered, it is cut off by a knife moved against it at the top of the anvil by a cam.

In another, the nails are made directly from the rod by a continuous operation, the blank from which the nail is to be made being first cut from the rod and then passed successively through a series of revolving dies operating in pairs, by which it is gradually drawn down and finished.
