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

1 . A wire saw comprising:
a frame: a housing coupled to and moveable relative to the frame; a plurality of wheels coupled to the housing; a wire cutting member wrapped at least partially around the plurality of wheels; and a visual indicator for indicating an amount of tension applied to the wire cutting member.

2 . The wire saw of claim 1 , 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.

3 . The wire saw of claim 1 , 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.

4 . The wire saw of claim 3 , wherein the range is about 40 pounds to about 60 pounds.

5 . The wire saw of claim 3 , 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.

6 . The wire saw of claim 5 , wherein the gap is within a range of sizes, and wherein the second state is one of an absence of a gap or a gap outside the range of sizes.

7 . The wire saw of claim 1 , 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.

8 . The wire saw of claim 1 , 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.
