Abstract

A rotary tube notching apparatus capable of operable attachment to a powered rotational drive device such as a drill, is comprised of a surface mountable tube support assembly capable of alternately receiving straight or bent tubing; a height adjustable carriage assembly pivotally mounted to the tube support assembly to enable offset notching, and a shaft assembly rotatably mounted to said carriage assembly for receiving a cutting tool.

Claims

1. A rotary tube notching apparatus capable of operable attachment to a powered rotational drive device such as a drill, the apparatus comprising:

a. a tube support assembly for alternately receiving straight or bent tubing;

b. a height adjustable carriage assembly pivotally mounted to said tube support assembly; and

c. a shaft assembly rotatably mounted to said carriage assembly for receiving a cutting tool.

2. The rotary tube notching apparatus of claim 1, wherein said tube support assembly is comprised of a vertical frame member having a planar tube receiving side and a recessed V-shaped tube receiving location.

3. The rotary tube notching apparatus of claim 2, wherein said planar tube receiving location includes a plurality of tube clamp mounting holes.

4. The rotary tube notching apparatus of claim 1, wherein said height adjustable carriage assembly is comprised of a horizontal swivel pivotally mounted to said tube support assembly, and a vertical slide in slidable engagement with said swivel, said vertical slide being adapted to receive said shaft assembly.

5. The rotary tube notching apparatus of claim 2, wherein said tube support assembly further includes a non-tube receiving side opposite said tube receiving side, and an angle indicator mounted to said non-tube receiving side for measuring the degree of rotation of said carriage assembly.

6. The rotary tube notching apparatus of claim 4, wherein said shaft assembly is mounted to said vertical slide above the plane of said swivel.
