WORKING TAPERS ON METALS

MACHINE A FAIRE CONE

Claims

Claim lst The production of tapers on the ends of metal bars by the process of compressing or squeezing the edges of the bars when heated, and then rolling out the tapers on the heated bars after the edge has been so shaped, the process of shaping the edge and rolling the taper being performed in two consecutive operations on the heated bar, by passing the same between compressing jaws and rolling out the taper between rolls suitably shaped and adjustable as to each other, substantiallyas specified. 2nd In a rolling machine, an upper roll C, driven independently of the lower roll and vertically adjustable, in combination with a segmental lower roll B suitably geared, the rolling surface of which is driven at a slightly lower rate of speed than that of the upper roll, substantially as specified. 3rd In a rolling machine, the combination, with compressing levers H, of adjustable compressing bits b, in the jaws thereof, the compressing levers being operated by an elliptical cam L, rigidly attached to, and adapted to partake of, the motion of the lower roll B, substantially as specified. 4th In a rolling machine, the combination, with the compressing levers H, carrying adjustable compressing bits b, and scaled adjusting wedges a, in the jaws thereof, of the springs I and K, and the elliptical cam L rigidly attached to, and adapted to partake of the motion of, the lower segmental roll B, driven by the geared wheel F, substantially as specified. 5th The upper roll C operated by the fly-wheel pulley E, in combination with standards N, screw di, spring d2 and movable journals D, DI, substantially as specified.
