Means for securing cutting or breaker elements to a rotatable member

Means for securing a pick to a rotatable member, comprising a rotatable member, said rotatable member having a circular outer peripheral surface, a first pick support, said first pick support being an annular element on the circular outer peripheral surface of said rotatable member and extending therefrom, said first pick support having an axially directed face, a plurality of radial slots being provided in said face, a continuous annular groove, said groove being disposed laterally of said slots and communicating therewith, said slots being open at their outer radial ends respectively, a second pick support on said rotatable member, one of the first and second pick supports being secured against rotation relative to the rotatable member, the other of the first and second pick supports being slidable on the rotatable member, said second pick support having a surface adapted to be held against a part of the pick, while another part of which is received in one of said slots and said groove, thereby releasably to retain the pick between said first and second supports.
