ABSTRACT:
This invention provides a safety means for powered machinery comprising a conventional wire mesh safety glove adapted for wearing by the machine operator. The machine with which it is used has a grounded frame, an electrical motor, a control switch, with the electrical motor being connected to a source of electrical energy through the control switch. A control safety circuit connects the electroconducting wire mesh safety glove and bypasses the conventional control switch for the machine which is in turn connected to the motor of the machine. The safety circuit includes a circuit breaking means, preferably a relay, whereby the relay will open and deprive the motor from electrical power whenever the wire mesh glove comes in contact with the grounded frame of the machine. An alternate form of the invention connects the wire mesh glove of the operator to the antenna of a wireless electromagnetic transmitter worn by the operator. The circuit breaking means includes a wireless electromagnetic receiver means which remains closed when receiving a radio signal, or any wireless signal, but which will open when the antenna of the wireless electromagnetic transmitter is grounded to the frame through the wire mesh glove touching the frame which serves to interrupt the transmission of the radio signal, or any wireless signal. This causes the electrical power to the motor to be interrupted.
