Abstract: A gauging device for gauging tapered rollers or the like, comprising feeding means for feeding each roller to a gauging station, first and second lower knife edges or the like projecting upwardly at the gauging station for supporting each roller, an end knife edge or the like at the gauging station for engaging one end of the roller, and a gauging head having an upper knife edge or the like projecting downwardly at the gauging station for engaging an upper portion of the roller, the gauging head having biasing means for biasing the upper knife edge downwardly against the roller, and output or indicating means for producing an output corresponding precisely with the position of the upper knife edge. The feeding means may comprise a rotatable wheel having pockets therein for carrying the rollers to the gauging station. A chute may be provided to feed the rollers into the pockets in the wheel. The gauging device is preferably inclined so that each roller is biased by gravity against the end knife edge.

Abstract: The disclosed gaging apparatus is especially advantageous for gaging the thickness of workpieces which are discharged in a stream from a double disc grinder, or some other similar machine. The workpieces travel along guide means, including a guide member along which one side of each workpiece is slidable. The other side of each workpiece is engaged by a contact bar which extends transversely to the direction of movement of the workpieces, and is generally parallel to such guide member. The contact bar is mounted on a carriage which is supported for movement toward and away from such guide member. In accordance with the present invention, the carriage is also supported for rocking movement so that the contact bar can align itself precisely with the abutting surface of each workpiece. A gaging head is employed to detect movement of the carriage toward and away from the guide member, such movement being due to variations in the thickness of the workpieces.
