An abrading machine has an indexing tool carrier for indexing a plurality of tools such as abrading belts, through plural stations including a single power station and other, unpowered idle stations. Hence the abrading machine provides the user with the option of sharpening a workpiece such as a wood chisel, knife or gouge and the like, on any of the given belts according to the user's selection. The abrading machine provides the economy of a single motor to power any of the given belts which at the time are indexed in the power station position. The other belts which are not indexed in the power station position sit idle. However, these other belts remain available for indexing into the power station position whenever the user wishes to work the workpiece on those belts.

[ I claim:] [1.] Abrading apparatus providing diverse belts utilized for giving edges to woodworking handtools by a worker manually manipulating a given woodworking handtool against the belts, said apparatus comprising:a stationary base;a plurality of belts and a corresponding roller assembly for each belt;a plural-belt belt carrier on which is mounted the plurality of belts by each belt's corresponding roller assembly;indexing means anchored to the base for movably mounting the plural-belt belt carrier and for indexing the plural-belt belt carrier through plural index positions such that the belts, one belt at a time, index through a single power station whereby the other belts other than a given one of the belts in the power station at the time, rest idle in other, unpowered idle positions;a source of drive power for driving the given belt which at the time is indexed in the power station; and,connection/disconnection means for connecting and disconnecting the source of drive power to and from the given belt which at the time is indexed in the power station to allow the indexing out of the given belt and the indexing in of another of the belts by changing the index position of the plural-belt belt carrier relative to the stationary base, which thereby avoids the needless waste of powering the other belts not at the power station at the time because said apparatus provides the worker with utilization of only one belt at a time in any case.
