Abstract
Abstract This invention relates to a series of different types of electrically driven trolley devices arranged to be suspended from and driven along a network of overhead trackways by frictional drive rollers. The trolleys disclosed may be driven in alternate manners by the frictional drive rollers either engaging the upper flange of the trackway as well as the lower flange thereof or only by engagement with the lower flange of the trackway. Current is derived from a cart which may be arranged to travel with the trolley or by electricifying portions of the trackways per se. Also revealed is a system of trackway controlling switches for moving the trolleys from horizontal to vertical directions and through junction points therebetween as well as means by which one trolley can pass another in the network system when desirable. Herein is also disclosed a system for accumulating containers of a particular design adjacent to a vertical shaft the accumulation area including mechanism for shifting the containers from a horizontal plane relative to the accumulation area and into the shaft to be attached to a trolley or for removing the containers from the trolleys to be returned to the accumulation area. Further, also disclosed is a support structure for novel containers which is controlled electrically to prevent the containers from deviating from desired positions while in transit on the trackway.
