A hand tool for treating the outside surface of a cylindrical component such as a pipe or tube grips the outside surface and can be rotated by inserting a finger into a finger engagement and spinning the tool about the component. Plumbers and the like clean the outside surface of pipes by using abrasive cloth, and the hand tool provides a tool for treating the surface with less effort. The hand tool has a lower body with a pivot adjacent one end and a treatment surface adjacent the other end, the lower body has a finger engagement adjacent the one end to rotate the tool about the component. A top body has a spring to join the lower body allowing the top body to pivot, and has a guide position to guide the component in contact with the treatment surface, the spring applies a force between the component and the treatment surface as the tool is rotated.

DETAILED DESCRIPTION The embodiments of the present invention in which an exclusive property or privilege is claimed are defined as follows: 1.
A hand tool for finishing exterior peripheries of cylindrical components of variable diameters comprising: a lower body having a pivot means adjacent one end and an abrasive strip located on a planar flexible backing member adjacent the other end, the lower body having a ring integral therewith adjacent the one end, the ring having an aperture for finger insertion, adapted to rotate the hand tool about the cylindrical component; a top body having spring means joining to the lower body, adapted to pivot at the pivot means, and having guide means to guide the cylindrical component in contact with the abrasive strip on the planar flexible backing member, the spring means adapted to apply force between the cylindrical component and the abrasive strip on the planar flexible backing member as the hand tool is rotated.
2.
The hand tool according to claim 1 wherein the abrasive strip extends beyond the flexible backing and has advance means to permit the abrasive strip to be advanced as the abrasive strip wears.
3.
The hand tool according to claim 2 wherein the advance means includes a shaft rotatable in an aperture, the abrasive strip passing around the outside of the shaft in the aperture, rotation of the shaft advancing the abrasive strip.
4.
The hand tool according to claim 1 wherein the flexible backing is foam plastic.
5.
The hand tool according to claim 1 wherein a coil of the abrasive strip fits in a cylindrical chamber in the ring, and including a passageway to feed the abrasive strip from the cylindrical member over the flexible backing, and including means to advance the abrasive strip to pass over the flexible backing.
6.
The hand tool according to claim 1 wherein the spring means comprises a coiled spring fitting into adjacent cavities in the lower body and the top body.

Description:
TECHNICAL FIELD The present invention relates to a hand tool for treating peripheral exterior surfaces of a cylindrical component
