Abstract

299,515. Denholm, T. D. July 28, 1927. Reversing-gearing.-A freely-mounted main driving member I drives a freely-mounted member O through reversing bevel gearing Y, h, Z; clutches W, M, keyed to the shaft U and normally held in inoperative position by springs j, k are engaged with the members I, O respectively, when desired, by rotation of sleeves i, m provided with helical surfaces engaging similar surfaces on stationary abutments n, R. The sLeeves i, m are operated through links r, s respectively from a shaft t and a sleeve a each provided with an actuating pedal 1, 2. The shaft t and sleeve a also carry members 3, 4 each provided with a slot 5 engaging a rod 6 controlling a brake band v normally held in engagement with a brake drum T<1> by a spring z ; through the rod 61, the brake is freed when either clutch is engaged. Specification 299,514, [Class 68 (i), Excavating eartli &c.], is referred to.
