  • Patent number: 4583775
    Abstract: A latch of the pull-up type for a cabinet door is latched and unlatched by turning the latch in one direction or the other. When the door is in latched position, rotating the latch in the unlatching direction initially causes a spring-biased shaft, which carries a latching pawl, to move axially inwardly. This inward movement of the shaft is permitted because a sleeve cam having cam slots is moved rotationally to present inwardly sloping cam surfaces to opposite ends of a cross pin which is mounted on the shaft and which functions as a cam follower. The shaft is prevented from rotating on its own axis until the cross pin, which also functions as a motion-control pin, is moved axially inwardly a sufficient distance to escape from axial motion-control slots provided in a motion-control sleeve which is mounted coaxially on the shaft.

  • Patent number: 4543748
    Abstract: A door assembly for a sterilizer includes a rectangular door on which is a vertical rail assembly movable horizontally toward and away from the door on threaded posts. Nuts carried by the rail assembly are rotated on the posts by sprockets entraining a motor driven chain. The rail assembly carries spring mounted axially retractable horizontal pairs of locking bars. The bars are inserted into and removed from sockets in a doorway frame by turning angularly as the rail assembly moves horizontally. A pressure responsive locking mechanism engages the sprockets to prevent their turning when the sterilizer is above a predetermined pressure. Cables carried by the locking bars actuate a switch in an alarm circuit for indicating that any one or more bars is not engaged properly in its respective socket. Limit switches stop operation of the motor when the rail assembly reaches extremes of inward and outward movement.

  • Patent number: 4492394
    Abstract: An adjustable grip latch has a slippable, friction-type drive connection provided between a shaft and a pawl which is carried on the shaft. A stop extends alongside the shaft for limiting the travel of the pawl to a range of movement extending between latched and unlatched positions. When the pawl is in its latched position it engages one portion of the stop. When the pawl is in its unlatched position it engages a different portion of the stop. The slippable drive connection transmits only a limited amount of torque from the shaft to the pawl, thereby enabling the shaft to move the pawl between its latched and unlatched positions, and enabling the shaft to rotate relative to the pawl when the pawl has engaged the stop. The slippable drive connection utilizes a wave spring washer to effect transmission of limited torque from the shaft to the pawl.

  • Patent number: 4395062
    Abstract: This invention pertains to a screw-nut mechanism for clamping two work pis together. In one application the mechanism is used to clamp a cover plate over an access opening in a vehicle hull or similar member. The screw-nut mechanism is specially designed for use where one face of the hull or similar fixed work piece is inaccessible for welding or otherwise affixing the nut on the concealed face of the inaccessible work piece. I provide a screw-nut mechanism that avoids the necessity for affixing the nut to the work piece. In my invention the nut is a loose hardware item that can have a thread length proportional to the expected load, thereby avoiding strength problems associated with the formation of threads directly in relatively thin work pieces.
