Rolling tool

A rolling tool for planishing cylindrical surfaces, of the type which comprises a support cone assembly, a cage axially displaceable and rotatably mounted on said cone assembly and a series of rollers disposed within said cage and bearing against said cone, said tool including apparatus for varying the axial position of said cone assembly relative to said cage, said apparatus comprising a mandrel having a threaded porton, a stop nut rotatably mounted on said threaded portion of said mandrel, a latch socket abutting said nut and axially moveably mounted on said mandrel between said nut and said cone assembly, an axially directed slot formed in said mandrel, key means spanning the space between said socket and said slot for non-rotatably coupling said socket and said mandrel, axially directed slot means on said socket, axially directed slot means on said nut, the slot means of said nut and said socket being shiftable into axial alignment responsive to rotation of said nut about said threaded portion of said mandrel, an adjustment sleeve encompassing said socket and said nut, said adjustment sleeve being axially movably mounted on said mandrel, a spline member on said sleeve, said spline member being shiftable with said sleeve relative to said nut and socket between an active position whereat portions of said spline lie within said slot means of said nut and said socket to thereby couple said nut and socket in torque transmitting relation and an adjustment position whereat said spline means of said sleeve is engaged with the slot means of said nut and cleared from said slot means of said socket, said nut, in said adjustment position of said sleeve being rotatable with said sleeve relative to said threaded portion of said mandrel and said socket to thereby shift the axial position of said nut along said mandrel.
