Abstract

708,501. Mining machines. UNION CARBIDE & CARBON CORPORATION. Sept. 30, 1952 [Dec. 1, 1951], No. 24398/52. Class 68(1) To indicate the hardness of the mineral being cut by the rotary cutter head 3 of a mining boring machine at a location remote from said head, a thermocouple 5 is positioned in a recess formed in a cutter tooth 1 on said head and is connected through a slip ring 9 on the head to a remotely situated electrical indicating means 8. In the electrical circuit 7 may be incorporated suitable relays automatically to stop rotation of the cutter when the temperature variation of the tooth exceeds predetermined limits.
