Patent number: 4530446Abstract: A gripping mechanism is mounted on a carriage and is adapted to be shifted back and forth along an inverted L-shaped path to pick up and transfer parts. Inverted L-shaped cam tracks are formed in a main support member and receive and guide rollers which support the carriage. The cam tracks and the rollers are arranged to allow the rollers to roll freely without skidding while preventing radial play between the rollers and the tracks. A flexible drive linkage is connected between the carriage and its actuator and is capable of yielding in both directions in order to prevent damage to the actuator if the carriage becomes jammed when the carriage is being either advanced or retracted. Before being picked up by the gripping mechanism, the parts are held in a track by an escapement having spring-biased fingers adapted to move between open and closed positions.Type: GrantFiled: January 20, 1984Date of Patent: July 23, 1985Assignee: Dixon Automatic Tool, Inc.Inventor: Paul H.

Patent number: 4499971Abstract: An improved system for monitoring lift chains included within mast assemblies in material handling vehicles disables downward movement of the forks upon detection of a first level of slackness in a lift chain. Since upward movement of the forks is not disabled, the forks may be raised to clear any obstruction causing the chain slackness. A lift chain may also be monitored to detect a broken chain in which case all vertical movement of the forks is disabled. In a material handling vehicle wherein the operator is elevated along a first mast and the forks are elevated along a second mast connected to an operator's platform, dual lift chains in the first mast are individually monitored for both slackness and breakage while dual lift chains in the second mast are monitored in common primarily to detect slackness. Lateral and rotational movement of the forks is also disabled for detection of a slack or broken first mast lift chain, but not for detection of a slack or broken second mast lift chain.Type: GrantFiled: April 22, 1983Date of Patent: February 19, 1985Assignee: Crown Controls CorporationInventors: Donald Luebrecht, Kim A.
