Abstract
A chain drive assembly for elevating a load such as a vehicle carriage on a leisure ride. The assembly comprises an endless loop lift chain and a plurality of drive chains. The lift chain has a plurality of chain links comprising a pair of laterally spaced outer link plates pivotally connected to inner link members disposed at least in part between the outer link members. The inner or outer link members of each link have a row of teeth for engagement in openings between links of the drive chains. The drive chains being disposed so as to engage the teeth at a rectilinear stretch of the chain loop so as to drive the chain in a longitudinal direction. The inner and outer links of the lift chain being arranged to define an opening designed to receive a projection on the load. The assembly serves to spread the load between the drive chains and their drive systems. The conveyor chain does not articulate under load and can be reduced in weight. This results in reduced chain wear, elimination of the polygonal effect, the facility to carry increased loads and enables the chain to travel at greatly increased speed.
