Abstract

A cutting apparatus includes a wire cutting member, a plurality of wheels about which the wire cutting member is at least partially wrapped, a first arm member supporting at least one of the plurality of wheels, and a second arm member supporting at least one of the plurality of wheels. The first arm member and the second arm member may be moveable between a first position, in which the cutting apparatus has a first size, and a second position, in which the cutting apparatus has a second size larger than the first size. A wire saw includes an adjustment member coupled to at least one of a plurality of wheels for moving the at least one of the plurality of wheels to adjust a tension of a wire cutting member. A wire saw includes a visual indicator for indicating an amount of tension applied to a wire cutting member.

First claim

The invention claimed is:

1. A cutting apparatus comprising:
a wire cutting member;
a plurality of wheels about which the wire cutting member is at least partially wrapped;
a first arm member supporting at least one of the plurality of wheels; and
a second arm member supporting at least one of the plurality of wheels;
wherein the first arm member and the second arm member are moveable relative to each other between a first position and a second position; and
wherein the at least one of the plurality of wheels supported by the first arm member is spaced further apart from the at least one of the plurality of wheels supported by the second arm with the first arm member and the second arm member in the second position.

2. The cutting apparatus of claim 1 , wherein the first arm member and the second arm member are rotatable relative to each other between the first position and the second position.

3. The cutting apparatus of claim 1 , wherein the cutting apparatus has a width of twelve inches, depth of twelve inches and a height greater than the width and the depth when in the first position.

4. The cutting apparatus of claim 3 , wherein the width of the cutting apparatus is at least partially defined by a distance between the at least one of the plurality of wheels supported by the first arm member and the at least one of the plurality of wheels supported by the second arm member, wherein the width of the cutting apparatus is greater when in the second position.

5. The cutting apparatus of claim 1 , wherein the cutting apparatus has a first width in the first position and a second width in the second position, wherein the first and second widths of the cutting apparatus are at least partially defined by a distance between the at least one of the plurality of wheels supported by the first arm member and the at least one of the plurality of wheels supported by the second arm member, wherein the second width is greater than the first width.

6. The cutting apparatus of claim 1 , further comprising an adjustment member coupled to at least one of the plurality of wheels for moving the at least one of the plurality of wheels to adjust a tension of the wire cutting member.

7. The cutting apparatus of claim 6 , wherein the at least one of the plurality of wheels is moveable between a first position and a second position, and wherein the wire cutting member has a greater tension when the at least one of the plurality of wheels is in the first position than when in the second position.

8. The cutting apparatus of claim 6 , wherein the adjustment member is coupled to at least two of the plurality of wheels for moving the at least two of the plurality of wheels to adjust a tension of the wire cutting member.

9. The cutting apparatus of claim 6 , wherein the adjustment member includes a plate and an actuator, and wherein the at least one of the plurality of wheels is coupled to the plate, and wherein the actuator is actuated to move the plate and the at least one of the plurality of wheels to adjust tension of the wire cutting member.

10. The cutting apparatus of claim 6 , wherein the adjustment member is moveable between a first position, in which a first tension is applied to the wire cutting member to perform a cutting operation, and a second position, in which a second tension is applied to the wire cutting member to facilitate removal of the wire cutting member from the plurality of wheels.

11. The cutting apparatus of claim 10 , wherein
the first arm member includes a first portion and a second portion rotatable relative to each other between a first position, in which an end of the first portion and an end of the second portion are coupled together, and a second position, in which the end of the first portion and the end of the second portion are uncoupled and spaced-apart from one another to provide a gap between the end of the first portion and the end of the second portion, and
the second arm member includes a first portion and a second portion rotatable relative to each other between a first position, in which an end of the first portion and an end of the second portion are coupled together, and a second position, in which the end of the first portion and the end of the second portion are uncoupled and spaced-apart from one another to provide a gap between the end of the first portion and the end of the second portion.

12. The cutting apparatus of claim 11 , wherein the wire cutting member is removable from the plurality of wheels with the adjustment member in the second position and the first portions and the second portions of the first and second arm members in the second position.

13. The cutting apparatus of claim 1 , wherein a length of the wire cutting member is between 95 inches and 105 inches.

14. The cutting apparatus of claim 1 , further comprising a visual indicator for indicating an amount of tension applied to the wire cutting member.

15. The cutting apparatus of claim 14 , further comprising a coupling member coupled to the frame and configured to rigidly couple the frame to an object, wherein the housing is configured to move relative to the frame and the object.

16. The cutting apparatus of claim 14 , wherein the visual indicator has a first state, in which the tension applied to the wire cutting member is within a range, and a second state, in which the tension applied to the wire cutting member is outside the range.

17. The cutting apparatus of claim 16 , wherein the range is 40 pounds to 60 pounds.

18. The cutting apparatus of claim 16 , further comprising an adjustment assembly coupled to the frame and the housing and configured to move the housing relative to the frame, wherein the adjustment assembly includes a handle, and wherein the first state is a gap between the handle and the frame.

19. The cutting apparatus of claim 14 , further comprising an adjustment assembly coupled to the frame and the housing and configured to move the housing relative to the frame, wherein the adjustment assembly includes a handle, and wherein the visual indicator is provided at least in part by at least one of the handle and the frame.

20. The cutting apparatus of claim 14 , further comprising an adjustment assembly coupled to the frame and the housing and configured to move the housing relative to the frame, wherein the adjustment assembly includes a handle, and wherein the visual indicator is a gap between the handle and the frame.

21. The cutting apparatus of claim 1 , wherein each of the first arm member and the second arm member include a first portion and a second portion rotatable relative to each other between a first position, in which the first portion and the second portion are coupled together, and a second position, in which the first portion and the second portion are uncoupled and spaced-apart from one another to provide a gap there between.
