Abstract

A kit is disclosed for cutting differing sized pipes internally. The kit includes a pipe cutting apparatus, and a plurality of assemblies. The pipe cutting apparatus includes at least one drive member. The plurality of assemblies, attachable to the pipe cutting apparatus, each include: (1) at least one feed member to extend at least one cutting member against a pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally; or (2) at least one clamping member to secure the pipe cutting apparatus to the pipe internally. Each of the plurality of assemblies differ in size so that differing sized pipes can be cut internally by the pipe cutting apparatus by attaching the appropriately sized assembly to the pipe cutting apparatus.

First claim

The invention claimed is:

1. A kit for cutting differing sized pipes internally comprising:
a pipe cutting apparatus comprising at least one drive member; and
a plurality of assemblies, attachable to the pipe cutting apparatus, each comprising: (1) at least one feed member to extend at least one cutting member against a pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally; or (2) at least one clamping member to secure the pipe cutting apparatus to the pipe internally;
wherein each of the plurality of assemblies differ in size so that differing sized pipes can be cut internally by the pipe cutting apparatus by attaching the appropriately sized assembly to the pipe cutting apparatus.

2. The kit of claim 1 wherein the plurality of assemblies each comprise the at least one feed member to extend the at least one cutting member against the pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally.

3. The kit of claim 2 wherein the at least one feed member comprises a wedge-shaped member, and each of the wedge-shaped members of the plurality of assemblies differ in size.

4. The kit of claim 2 wherein the plurality of assemblies each comprise the at least one cutting member.

5. The kit of claim 1 wherein the plurality of assemblies each comprise the at least one clamping member to secure the pipe cutting apparatus to the pipe internally.

6. The kit of claim 5 wherein the plurality of assemblies comprise varying height clamping assemblies.

7. The kit of claim 6 wherein the plurality of assemblies comprise differing sized feet and legs which can be combined in differing combinations to vary the height of the clamping assemblies.

8. A kit for cutting differing sized pipes internally comprising:
a first pipe cutting apparatus comprising: at least one cutting member to cut a first pipe internally; at least one drive member to rotate the at least one cutting member to cut the first pipe internally; at least one feed member to extend the at least one cutting member against the first pipe internally and to retract the at least one cutting member from the first pipe internally; and at least one clamping member to secure the first pipe cutting apparatus to the first pipe internally; and
a second pipe cutting apparatus, differing in size than the first pipe cutting apparatus, comprising at least another cutting member to cut a second pipe internally with the second pipe differing in size than the first pipe; at least another drive member to rotate the at least another cutting member to cut the second pipe internally; at least another feed member to extend the at least another cutting member against the second pipe internally and to retract the at least another cutting member from the second pipe internally; and at least another clamping member to secure the second pipe cutting apparatus to the second pipe internally.

9. The kit of claim 8 wherein the at least one cutting member, the at least one drive member, the at least one feed member, and the at least one clamping member of the first pipe cutting apparatus are disposed coaxially relative to one another, and the at least another cutting member, the at least another drive member, the at least another feed member, and the at least another clamping member of the second pipe cutting apparatus are disposed coaxially relative to one another.

10. The kit of claim 8 wherein the first pipe cutting apparatus further comprises at least one motor to drive the at least one drive member in order to rotate the at least one cutting member, and to move the at least one feed member to extend the at least one cutting member against the first pipe internally, and the second pipe cutting apparatus further comprises at least another motor to drive the at least another drive member in order to rotate the at least another cutting member, and to move the at least another feed member to extend the at least another cutting member against the second pipe internally.

11. The kit of claim 10 wherein the first pipe cutting apparatus further comprises at least one clutch member to automatically decouple the at least one feed member from the at least one motor when a force placed on the at least one cutting member exceeds a limit or to manually decouple the at least one feed member from the at least one motor when the at least one clutch member is manually moved to a position, and the second pipe cutting apparatus further comprises at least another clutch member to automatically decouple the at least another feed member from the at least another motor when another force placed on the at least another cutting member exceeds another limit or to manually decouple the at least another feed member from the at least another motor when the at least another clutch member is manually moved to another position.

12. The kit of claim 8 wherein the at least one clamping member of the first pipe cutting apparatus is manually operated, and the at least another clamping member of the second pipe cutting apparatus is manually operated.

13. The kit of claim 8 wherein the first pipe cutting apparatus further comprises at least one centering member to center the first pipe cutting apparatus within the first pipe, and the second pipe cutting apparatus further comprises at least another centering member to center the second pipe cutting apparatus within the second pipe.

14. The kit of claim 8 wherein the at least one feed member of the first pipe cutting apparatus is different in size than the at least another feed member of the second pipe cutting apparatus, and the at least one clamping member of the first pipe cutting apparatus is different in size than the at least another clamping member of the second pipe cutting apparatus.

15. A method of cutting differing sized pipes internally comprising:
clamping a pipe cutting apparatus within a first pipe using a first clamping member assembly of the pipe cutting apparatus;
extending at least one cutting member of the pipe cutting apparatus against an internal surface of the first pipe using a first feed member assembly of the pipe cutting apparatus;
rotating the at least one cutting member with at least one drive member of the pipe cutting apparatus in order to cut the internal surface of the first pipe with the at least one cutting member;
replacing the first clamping member assembly with a second clamping member assembly differing in size than the first clamping member assembly and clamping the pipe cutting apparatus within a second pipe differing in size from the first pipe using the second clamping member assembly; or replacing the first feed member assembly with a second feed member assembly differing in size than the first feed member assembly and extending the at least one cutting member or at least another cutting member of the pipe cutting apparatus against an internal surface of the second pipe using the second feed member assembly; and
rotating the at least one cutting member or the at least another cutting member with the at least one drive member of the pipe cutting apparatus in order to cut the internal surface of the second pipe.

16. The method of claim 15 further comprising replacing the first clamping member assembly with the second clamping member assembly differing in size than the first clamping member assembly and clamping the pipe cutting apparatus within the second pipe differing i
