Abstract

642,903. Automatic thickness-control systems. HARGREAVES, F. G., HARGREAVES, L. S., and SHARDLOW ELECTRIC WIRES, Ltd. March 31, 1947, No. 8672. [Class 38 (iv)] [Also in Group XIX] Variations in the thickness of moving material, e.g. a covered wire 20, cause movement of a material-contacting member 17 connected by members (see Group - XIX) to close one of a pair of electric switches 34, 35 and 36, 37 to operate means controlling the thickness. Each switch may be connected to a low voltage relay (not shown) . connected across one coil of a, reversing contactor. Energization of either coil will operate a reversible electric motor to adjust the speed at which the wire is drawn off from a forcing machine, thus altering the thickness of the wire covering.
