Abstract
A driving sprocket to drive conveyor chain on a finger jointing machine having a base plate with central aperture therein. Drive hubs are mounted on opposed faces of the base plate and are adapted to be rotated by conventional power transmission equipment. The drive hubs project into the central aperture and clutch plates are interposed in operative series relation between the drive hub and the related face of the base plate. The drive hubs directly and solidly drive the clutch plates. The clutch plates frictionally drive the base plate. Caliper clutch assemblies control the level of frictional engagement between the respective clutch plates and the related face of the base plate.
