Abstract: This invention is an installation of a safety apparatus to prevent safety problems of machine tools caused in work-loading process. The safety apparatus comprises an actuator, used for connecting circuits of the machine tool to control its power on-off status, and a storing unit to ensure the chuck wrench resting at a designated safe position. This safety system will activate the actuator when the chuck wrench is returned to the designated position and, therefore, it will keep the circuits of the machine tool stay active during the machining operation. On the other hand, this safety apparatus will remain in power-off status if the chuck wrench is not placed at the designated position and, therefore, it will make the power circuits open and paralyze the machine tool operation.

Abstract: An electrical switch assembly for actuating an electrical circuit by closing at least one pair of conducting contacts in a sliding manner is disclosed. The assembly includes a contact carrier within a switch housing, a spring attached to the carrier that biases the carrier in an electrical circuit open position, a slot connected to the carrier that receives a force transfer member, and a force transfer member that is insertable into the slot and transfers a force applied by a switch operator to an angled wall portion of the slot. The angle of the wall portion is preferably 45-degrees relative to the axis of travel of the force transfer member. In operation, when the force transfer member is inserted into the slot and pushes against the angled wall, the carrier is displaced approximately orthogonal to the insertion direction of the force transfer member to move the contacts in the carrier from an electrical circuit open position to an electrical circuit closed position.

Abstract: A lockable switch mechanism for a machine guard includes a switch plunger and locking and switch mechanisms. The plunger moves, upon insertion of an actuator, between two positions to actuate the switch mechanism and is locked by the locking mechanism, which has one locking member biased against a surface of the plunger and another locking member that is displaceable between locked and released positions. The plunger has an annular shoulder that displaces the first locking member when the plunger is moved. The second locking member prevents displacement of the first locking member by the plunger to thereby prevent movement of the plunger. Thus removal of the actuator is prevented unless the second locking member has been moved to the unlocked position when the machine is in a safe condition.

The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition.

Abstract: An operating arrangement is provided for a mechanism or the like, e.g. an operating mechanism for a circuit interrupter for electrical power transmission and distribution systems where the operating mechanism operates on stored energy and requires a recharging operation after the stored energy is utilized to operate the circuit interrupter.
