Abstract

104,281. Higginson, J., and Arundel, H. June 1, 1916. Milling screws.-Screw-thread milling machines have the work spindle automatically returned by a weight after the completion of the cut. As applied to a spindle driven through a drop-box worm j tripped at n, a pulley c supports a chain and weight a. A ratchet-wheel f prevents the weight from returning the spindle until the milling-cutter carriage is reversed when a yielding connexion at h trips the pawl. The ratchet and pawl may be replaced by a brake. In modifications, the pawl may be released by hand, or the weight may be so proportioned that return will not take place until started by a spin of the hand-wheel.
