  • Hand operated actuator for rotary storage cabinet
    Patent number: 5494347
    Abstract: A rotary cabinet with a self-latching and positioning rotor is provided with an improved latch mechanism. The latch is operated by a sliding hand actuator connected by links and levers to a latch member. To operate, the actuator is lifted to release the rotor. An air cylinder retards the return of the actuator and latch member to the latched position. While the rotor is released, the rotor is rotated to a desired position. The latch returns to the latched position and restrains the rotor. Materials can be stored in or retrieved from shelves on the rotor.
