ABSTRACT:
The power supply to the motor of a glass chopper is rerouted so that the motor cannot be operated unless the cover enclosing the cutter blades is in place. The stud which normally supports the cover is replaced with a conduit which has an axial passage from end to end. A fitting attaches the cover to the conduit to hold the cover in position over the cutting blades. The fitting is adapted to secure a power supply line to said cover. Thus, the motor can only be actuated when the cover is in position enclosing the cutting means at which time the power supply line is in communication with the motor through the conduit. When the cover is removed from its protective position, the power supply line actuating the motor is disconnected and the glass chopper can be safely serviced.
