Abstract : Rail interlocking and hoist stop apparatus for material handling systems movable rail and a slave stop assembly located on the of the type wherein a hoist travels between a movable rail and a stationary rail comprising a master stop assembly located on the stationary rail. The apparatus is manually actuated throught a mechanical linkage which pushes a master pin in the master stop assembly toward the slave stop assembly. If the rails are in proper alignment, the end of the master pin is inserted into a bore in the slave assembly where it displaces a slave pin. The movement of the slave pin causes a crossover pin in the slave assembly to be partially inserted into a bore in the master assembly where it displaces a locking pin. The movement of the slave pin and the crossover pin in the slave assembly is rigidly coupled to stop pins located in the slave assembly and which are disposed in the path of the hoist when the stop system is unactuated. Likewise the movement of the locking pin in the master assembly is rigidly coupled to stop pins located in the master assembly.
