Abstract
A drive assembly has two parallel roller link drive chains which are driven by sprocket drives. The drive chains are transversely connected at spaced intervals by a dog support which has a planar base and two walls which extend upwardly from the base. The rollers of two parallel drive chain links are rotatively mounted to the walls and a plastic drive dog is attached to the support base. The drive dog has two projecting members and a base which define a depression which is radiused to accept a tow chain roller. The depression is spaced from the support base such that the horizontal rotational axis of the engaged tow chain roller and the horizontal rotational axes of the chain rollers are in the same plane. Stabilizing rollers are mounted to the support walls coaxially with the drive rollers and are supported in a formed track section. The dog support carries the shaped dog into engagement with the rollers of the tow chain.
