Abstract
A diamond wire saw and method provides a frame that includes a clamp that attaches to a target (e.g. piling, beam, tubular), an elongated toothed rack extending away from the mount and target, and a moving portion that carries the diamond wire and motor drives that advance the moving portion toward the target and along the toothed rack while driving the wire around roller guides.
Claims20
A wire saw apparatus comprising:
- a) a frame that includes a clamp configured to attach to a target that is to be cut and a moving portion mounting to the clamp for movement relative to the clamp;
- b) an elongated linear beam mounted to the clamp and extending away from the clamp and target;
- c) the moving portion including a pair of arms disposed on opposing sides of the beam, an open end positioned near the clamp and a transverse bar that connects the arms opposite the open end;
- d) the moving portion having a powered driver operably connected to the linear beam which driver effects linear movement of the moving portion of the frame along the beam;
- e) a plurality of roller guides on the moving portion of the frame including at least one roller guide mounted at the free end of each arm;
- f) a drive roller on the moving portion, the drive roller being rotatable by a powered motor drive;
- and
- g) a diamond wire wound upon the drive roller and guide rollers so that when the drive roller is rotated, the diamond wire travels around the moving portion and from one roller to another roller.

A wire saw apparatus comprising:
- a) a clamp configured to attach to a target that is to be cut;
- b) an elongated linear beam mounted to the clamp and extending away from the clamp and target;
- c) a moving frame mounted on the elongated beam and being movable along the beam, the frame including a pair of arms disposed on opposing sides of the beam, an open end positioned near the clamp and a transverse bar that connects the arms opposite the open end;
- d) a motor operably connected to the linear beam which motor effects linear movement of the moving frame along the beam;
- e) a plurality of roller guides on the moving portion of the frame including at least one roller guide mounted at the free end of each arm;
- f) a drive roller on the moving portion, the drive roller being rotatable by a second motor drive;
- g) a diamond wire wound upon the drive roller and guide rollers so that when the drive roller is rotated with the second motor drive, the diamond wire travels around the moving portion and from one roller to another roller.

A wire saw apparatus for cutting underwater targets, comprising:
- a) a frame that includes a fixed mount and a traveling frame section;
- b) the mount providing a bracket and a clamp that enables a connection to be made between the bracket and the target;
- c) the mount including an elongated bar that is attached to the bracket and extending away from the bracket and the target;
- d) a first motor drive on the traveling frame section having a pinion gear that engages the rack;
- e) the traveling frame section having a transverse beam and a pair of opposed generally parallel arms, each having an arm end and an open throat in between the arm ends;
- f) a plurality of roller guides on the frame;
- g) a diamond wire belt supported by the roller guides, the belt extending along each arm, the transverse beam and the throat;
- and
- h) a second motor drive that drives one of the roller guides and the wire belt.

A method of cutting an underwater target, comprising the steps of:
- a) lowering a cutting apparatus to a position that is next to an underwater target to be cut;
- b) attaching the cutting apparatus to the target with a clamping mechanism;
- c) wherein in step “b” the cutting apparatus provides a frame that includes a clamp configured to attach to a target that is to be cut and a moving portion mounting to the clamp for movement relative to the clamp, an elongated beam mounted to the clamp and extending away from the clamp and target, the moving portion includes a pair of arms disposed on opposing sides of the beam and an open end positioned near the clamp and a transverse section that connects the arms opposite the open end and wherein a diamond wire is supported for travel upon the frame, the wire connected to a plurality of rollers including at least one powered drive roller that moves the wire;
- d) advancing the moving portion toward the target while the diamond wire is traveling upon the rollers;
- e) wherein in step “d” a driver engages the elongated beam and advances the moving portion.
