Abstract

A complete and portable tool for retaining round, square or other non-flat stock, especially pipes, in a secure fashion while cutting and related operations are performed thereon. The portable pipe cutting tool includes an adjustable work support, V-shaped trough, chain and tightening device, catch tray, left and right support arm bracket, mounting stand, and power tool having a base portion that, as a unit, secure the pipe in place while being cut, grooved or otherwise worked on, by an operator. The portable pipe cutting tool prevents sideways, upward, rotational or other movement of the pipe during such operations.

Claims

1. A portable apparatus for securely retaining a workpiece while operations are performed thereon, comprising:

(a) a support frame including an elongated upper horizontal member and a first and second pair of adjustable and foldable legs disposed in spaced relationship to each other and mounted to opposite ends of the horizontal member;

(b) an elongated tray slidably mounted on top of said horizontal member and being moveable between an extended and a retracted position, wherein in the extended position said tray projects outward from said horizontal member so as to be located immediately beneath at least a segment of the workpiece while operations are performed thereon for capturing severed segments of said workpiece and preventing said severed segments from contacting the floor or ground;

(c) a V-shaped, immovable platform mounted to the horizontal member above said slidable tray for steadily retaining said workpiece and preventing rolling thereof, a segment of workpiece to be operated on projecting above at least a portion of said slidable tray; and

(d) a left and right mounting stand for releasably attaching a power tool, each mounting stand including a bracket for securing the stand to the top surface of the support frame.

2. The portable apparatus of claim 1 further comprising an adjustable tightening device connected to said support frame and releasably extending about said workpiece for fixedly securing said workpiece within the V-shaped platform.

3. The portable apparatus of claim 1 further comprising a brace attached across said first and second pair of legs for storing construction and building materials.

4. The portable apparatus of claim 1 further comprising said power tool having a base for secure and releasable mounting to said left and right mounting stand, respectively.

5. The portable apparatus of claim 1 wherein said power tool comprises an electric saw.

6. The portable apparatus of claim 1 further comprising a handle for carrying the apparatus when the apparatus is in a compacted position.

7. A portable apparatus for securely retaining a pipe while operations are performed thereon, comprising:

(a) a support frame including an elongated upper horizontal member and a first and second pair of adjustable and foldable legs disposed in spaced relationship to each other and mounted to opposite ends of the horizontal member;

(b) an elongated tray slidably mounted on top of said horizontal member and being moveable between an extended and a retracted position, wherein in the extended position said tray projects outward from said horizontal member so as to be located immediately beneath at least a segment of the pipe while operations are performed thereon for capturing severed segments of said pipe and preventing said severed segments from contacting the floor or ground;

(c) a V-shaped, immovable platform mounted to the horizontal member above said slidable tray for steadily retaining said pipe and preventing rolling thereof, a segment of pipe to be operated on projecting above at least a portion of said slidable tray; and

(d) a left and right mounting stand for releasably attaching a power tool, each mounting stand including a bracket for securing the stand to the top surface of the support frame.

8. The portable apparatus of claim 7 further comprising an adjustable tightening device connected to said support frame and releasably extending about said pipe for fixedly securing said pipe within the V-shaped platform.

9. The portable apparatus of claim 7 further comprising a brace attached across said first and second pair of legs for storing construction and building materials.

10. The portable apparatus of claim 7 further comprising said power tool having a base for secure and releasable mounting to said left and right mounting stand, respectively.

11. The portable apparatus of claim 7 wherein said power tool comprises an electric saw.

12. The portable apparatus of claim 7 further comprising a handle for carrying the apparatus when the apparatus is in a compacted position.
