Abstract: An expandable abrading tool (20, 20a, 20b) disclosed includes a rotatable arbor (22) and an abrasive insert (24, 24a, 24b) having stacked washers (26) which receive the arbor and are mounted thereon in a clamped relationship. Each washer has a round outer edge including an abrasive (32) secured thereto for performing a cutting operation upon tool rotation. The washers each have a frustoconical shape that points toward one axial end of the insert. A threaded clamp (38, 40, 42, 44) which provides a means for clamping the ends (34, 36) of the insert is adjustable to increase the clamping force in order to flatten the washers and thereby control the washer diameters. The insert can thus be initially sized for use and can be adjusted to compensate for wear of the abrasive.

Abstract: Apparatus for sensing and measuring the torque output of a rotary device such as a gear reduction box by inserting an especially machined or configured adaptor between the shaft bearing and the bearing mounting housing. This adaptor transducer will have strain gages mounted on it in spaced relationship so that the tangential force from the gears reacting on a shaft will produce a deflection in the adaptor transducer which will be detected by the strain gages. The strain gage signal then will be sensed, amplified and can be recorded on an analog read out type meter or monitored continuously on a pen-type recorder or other conventional instruments. The strain gages can be calibrated so the output of the recorder will convert the signal into a direct reading of the torque output transmitted through the gear reduction box.
