Abstract: A roller assembly for use with a conveyor for transporting a workpiece wherein the drive force applied by the roller is adjustable independent of the force generated by placing a workpiece on the roller. The roller includes an inner sleeve secured to a drive shaft of the conveyor. A roller is disposed about the inner sleeve and is frictionally fit along an interface between the roller and an inner sleeve such that when a weight is placed upon the roller, the frictional force occurring between the interface between the roller and sleeve causes the rotating inner sleeve to impart motion to the roller thus moving the workpiece. The roller includes a connection to the inner sleeve such that the coupling or frictional force between the roller and the inner sleeve is independently variable of any force generated by placing a workpiece on the roller.

Abstract: A rotary impact apparatus comprises an input shaft capable of attachment to an electric drill and arranged to drive an impact assembly through a cone clutch and an output shaft capable of being driven by the impact assembly. The clutch is adjustable by means of a nut and a spring to vary the torque at which drive to the output shaft is disengaged. The impact assembly comprises two rockers adopted to drive the output shaft in respective directions. Each rocker is biased out of engagement with the output shaft by a rocker spring but is unbalanced and rotation of the impact assembly through the clutch by the input shaft creates a centrifugal force on it against the rocker spring whereby it engages the output shaft to rotate the output shaft until resistance to rotation is such that the clutch disengages and rotation of the impact assembly stops.

The overload housing has a smooth internal clutch face which interfaces with a corresponding smooth outer clutch face on the clutch body to drive the quill pinion shaft. The force with which the clutch body is passed against the smooth internal clutch face is adjustable to vary the resistance torque on the quill pinion shaft at which the interacting clutch faces will slip and allow the overload housing to rotate independently of the clutch body.

Engagement and release are effected by slowly turning the coupling half by means of the drive transmission while a brake device engages dogs on the coupling half to prevent the latter rotating. The coupling sleeve is flexibly attached to the flange by sheet metal laminate compensating elements but mobility of the sleeve is restricted by a support element on a shaft extension.
