A vibratory conveyor and abrader has a vibrated feed path covered with a pile material having resilient bristles inclined toward the direction of feed to move objects along. The pile material includes bristles having particles of an abrasive material extending to the tips of the bristles, and the device is arranged for urging the objects into abrasive engagement with the abrasive bristles as the objects move in the direction of feed for evenly abrading the objects as they proceed. This is done by impeding the motion of the objects in the direction of feed, having the abrasive bristles oppose the motion of the objects while non-abrasive bristles feed the objects, rotating the objects around a vertical axis as the objects move in a direction of feed, using combinations of abrasive and non-abrasive bristles inclined at angles relative to each other, or using a guide rail and inclining bristles to roll the objects along the guide rail as the objects move in the direction of feed.

A bar end positioner for face-off of a new bar is applied to a magazine bar feeder having a stock tube and a cable drive for feeding bars to a bar working machine. The bar end positioner includes a gate movable to block off the end of the stock tube and a stock stop valve for detecting the engagement of a bar end with the gate. When the stock stop valve operates, a movable clamp closes onto the cable and then the gate moves clear of the stock tube so that the cable and the bar advance until the clamp reaches a stop and the bar reaches a face-off position. This starts the bar working machine which then releases the clamp so it returns to its start position.

Cooling means for a friction clutch or disc brake wherein superior cooling is achieved by impinging high velocity jets of relatively cool air against the frictionally engageable surfaces of the clutch or brake. Fluid passages are provided in one or more of the engagement members and these communicate with jet orifices which direct air introduced into the passages under pressure against the friction surfaces of the adjacent members. The orifices are arranged so that the air jets are substantially perpendicular to the adjacent friction surfaces and cool the latter far more effectively than can be accomplished by means of laminar flowing cooling air.
