Abstract
Diversion-type switches and cross-type switches are provided for inclusion in suspended rail conveyor arrangements to form a rail conveyor system. Each of said switches includes at least one shiftable rail section movable between a first position of cooperation with spaced rails of one conveyor pathway and a second position of cooperation with a spaced rails of another conveyor pathway. Rail alignment and load transmitting means, in the configuration of coacting fingers and seats, are disposed at the respective ends of the shiftable rail section and fixed rail section and coact therewith so that load forces acting on the shiftable rail section act to align the shiftable rail section with the spaced rails of the respective conveyor pathways and so that load forces applied to the shiftable rail section are transmitted directly to the fixed rail section. Operating means, including cams and cam followers are provided to move the shiftable rail section to separate the rail alignment and load transmitting means to shift the shiftable rail section and to bring together the rail alignment and load transmitting means.
