Title: Radio control for press

Abstract: A radio control for a press includes a radio receiver connected to actuate the press upon receipt of a predetermined radio signal, and a belt-mounted transmitter worn by the press operator. Two series-connected manually operated transmitter actuating buttons are mounted on the belt at opposite sides of the operator. The buttons must be simultaneously pushed to actuate the transmitter and, since the buttons are on opposite sides of the operator, he must use both hands to push them at the same time. This precludes the possibility that an operator's hands will be in the danger zone of the press during operation, while at the same time providing relatively unlimited freedom of position for the operator. Provisions are made for two or more receivers and transmitters to equally protect two or more operators, and for overriding the belt transmitter in the event of special workpiece set ups.
