Abstract

Abstract A welder's mask having a remote controlled eye shield for allowing the user to remotely and independently control opening of the eye shield when not needed, and closing of the eye shield when needed, which includes a conventional welder's mask housing having a viewing opening means to mount the mask housing upon the user's head. A conventional welder's eye shield is adjustably secured to the mask housing in such a way that it is moveable between a closed position covering the viewing opening, and an open position uncovering the viewing opening. A motor means, mounted on the mask housing, has a connecting means between the motor means and the eye shield which transmits the output of the motor means to the eye shield to move it between the open and closed positions. An independent remote control radio transmitter means has a control switch means which, when operated, sends appropriate radio signals to a radio receiving means which receives and converts the radio signals into electrical signals which are transferred to instruct the motor means to move the eye shield between the opened and closed positions, according to desire. The motor means and transmitter means are operatively connectable to a first power means which can be secured to the mask housing. The transmitter means is operatively connected to a second power means for its independent and remote operation.
