437,052. Operating clutches. STANLEY, G. E., 92, Godiva Street, Coventry. June 14, 1934, Nos. 17603, 31992, and 34559. [Class 80 (ii)] [See also Group XXXIV] A clutch-withdrawal ring is formed of asbestos fabric or pulp impregnated with synthetic resin or other bonding solution. In one form, the bush 12 of the material specified is mounted on the driven shaft 13 of a plate clutch for motorvehicles and carries a ball-bearing 22, 23 enclosed in a cover 24 having a radial flange 25 engaging the clutch-operating levers 14; the actuating fork 32, by which the bush 12 is slid along the shaft 13, engages the radial flange 21. Lubricant is supplied through a groove 27 and passages 26, the shaft 13 having abore 28 fitted with a permeable plug 29 to control the flow. In a modification, the ball bearing is replaced by a cast-iron or other ring rotatablymounted on the bush and formed with recesses to receive the clutchoperating levers. The fork 32 engages flats on the bush to prevent rotation thereof. The bush 12 may be provided with drilled-out holes closed by plugs, forming lubricant reservoirs. Those parts of the bush which do not require lubrication may be surrounded by a casing or coated with resin, gum or paint to prevent percolation.
