Abstract

598,204. Safety devices for machinery. SOC. ANON. A. CITROEN. Aug. 13, 1945, No. 20811. Convention date, March 25, 1943. [Class 80(iv)] In a safety device for a machine tool, an electrode 6, located near the tool 1, is insulated from the machine and is connected to a high-frequency amplifier so that any change in the capacity of the electromagnetic field 7 acts to stop the machine or operate a signal. Thus in a rubber-shearing machine the rubber sheets 4 pass over the table 3 without affecting the field 7, but if the operator's hand enters the field the amplifier actuates a warning signal or stops the machine. An additional electrode 9 may be used behind the tool 1. The electrodes 6, 9 may be of strip copper and have shields 8, 10. Alternatively the tool itself may form the electrode. In a wood-moulding- cutting-machine the electrodes 16, Fig. 2, are carried on guides 15. Should the operator's hand enter the electromagnetic field, the variation in capacity will influence the amplifier and a series of relays to close the circuit of an electromagnet 19 thus releasing a spring 20 attached to the guide 15 which is thus rotated through about 20 degrees about a spindle 21, to push the hand away.
