Abstract: An electromechanical rotary switch actuator for the operation of doors of mass transit vehicles. The switch actuator discloses a crew switch actuator that incorporates the features of a rotary switch while at the same time provides low cost manufacturing of the switch actuator apparatus. The invention is a simple, yet innovative, apparatus whereby rotational control of the switch assembly is provided by a retaining member which mates with a slot grooved into a shaft mounted for rotation in the actuator body. The longitudinally axial dimension of the actuator body is small which enables the apparatus to be flush mounted to the outside walls of the transit vehicles. The crew switch actuator disclosed is operated not only by a detachable key which is also disclosed, but also may be actuated with the same keys currently being used to operate the door control switches of most mass transit systems.

Abstract: This invention relates to a screw lock, characterized in that the screw key screws into a keyway, and the slots on the top ring screw of the screw key provide a convex-concave match with switch points in the cylinder. The screw key is then pushed in and turns the cylinder to effect locking and unlocking. The keyway of this invention is adapted to accept the spiral screw shape, and accordingly, the form and the mechanism of the switch points are not seen. Thus, the form and mechanism of the switch points in the cylinder is unknown. Also, conventional keys or wires cannot be inserted into the spiral screw hole. In case other keys are inserted into the keyway, the set points in the cylinder prevent the key form being further pushed in and prevent turning of the cylinder to effect unlocking.

Abstract: A key-operated device, for example for controlling access to switch gear or potentially dangerous machinery, has a rotary motion with an axially inserted key but departs from the usual barrel lock construction which is sensitive to foreign matter. Instead it has a faceplate in front of a stationary body with a cylindrical member rotatable in it and having a recess for the key and circumferentially spaced notches in a flange close behind the plate and prevented from direct access through the keyhole by a fixed axially extending wall on the back of the plate but accessible by appropriate lugs on the key when the latter is inserted. The rotatable member is connected through a spindle to a switch, valve or latch or other actuated device.

Abstract: Certain types of key-operated padlocks are provided with warded inserts accessible for key insertion through an opening in the bottom of the padlock body. In the present structure when the proper key is inserted into the warded insert (housed within the padlock body) the cuts in an edge of the key shank match and register with similar cuts or notches in the insert permitting the key to be turned with the specially formed tip of the key engaging a web on the bottom of the plug extension blade within the lock body with special cuts or notches and nodules in and on the key tip engaging companion formations in and on the bottom of the plug extension whereby turning movement of the key will turn the plug extension to the extent necessary to retract certain shackle holding levers and thus release the padlock shackle.
