A pick box (1) of a tooling system for mineral winning etc., has an elongated aperture (4) to receive, in use, a removable liner sleeve (6) of the tooling system, the box (1) providing a seating surface (7) extending orthogonally with respect to the axis (5) of the aperture (4). The external periphery of the sleeve (6) and the internal periphery (8) of the box aperture (4) are so profiled, e.g. hexagonally, as to prevent relative rotation and the internal periphery of the box aperture is interrupted at (11) to provide at least one surface for engagement, in use, with a retainer device (12) of an inserted sleeve (6), whilst the sleeve has an external groove (22) to receive a retainer device (12). The invention also includes a sleeve (6) having an enlarged head (16), a longitudinal circular bore (26), and a circumferential groove (22) fitted with a retainer ring (12). The invention further includes a box (1) and a sleeve (6) in combination, and a drum (3).

[ What we claim is:] [1.] A pick box comprising: an elongated aperture to receive, in use, a removable liner sleeve having an enlarged head, said pick box providing a seating surface extending orthogonally with respect to said elongated aperture for engagement, in use, by the enlarged head, wherein the internal periphery of said elongated aperture and the complementary external periphery of an inserted sleeve are so profiled as to prevent relative rotation, and said internal periphery of said elongated aperture is interrupted to provide at least one surface for engagement, in use, with a retainer device of an inserted sleeve, said interruption to said internal periphery of said elongated aperture being by the provision of a plurality of recesses or grooves formed by a screw-thread cut into said internal periphery of said elongated aperture. [8.] In combination, a pick box and a sleeve,said sleeve comprising an enlarged head at one end thereof which head provides an annular seating surface, and a frusto-conical flank, whilst a longitudinally extending, circular section bore is provided co-axially of said sleeve and adapted, in use, to releasably receive a circular section shank of a replaceable, mineral cutter pick, and said sleeve having, intermediate its ends, a circumferential groove into which is fitted a retainer ring, which projects beyond the external periphery of said sleeve;said pick box comprising an elongated receiving aperture to receive, in use, said sleeve, said pick box providing a seating surface extending orthogonally with respect to said elongated aperture for engagement, in use, by said enlarged head of said sleeve, wherein the internal periphery of said elongated aperture and the complementary external periphery of said sleeve when inserted are so profiled as to prevent relative rotation, and said internal periphery of said elongated aperture is interrupted to provide at least one surface for engagement, in use, with a retainer device of said sleeve when inserted, said interruption to said internal periphery of said elongated aperture being by the provision of a plurality of recesses or grooves formed by a screw-thread cut into said internal periphery of said elongated aperture.
