Abstract

A structurally integrated high pressure, hydraulic hand-held tool for cutting the hooves on horses. The tool includes a handle, with a hydraulic flow line provided centrally therethrough, a chamber integrated into the upper end of the handle, the chamber comprising a piston, so that as hydraulic fluid is exerted into the handle chamber, it forces the piston upwardly and out of the handle chamber, and at the upper end of the tool are a pair of mounts, that pivotally connect a pair of opposing jaws, each jaw having a cutting blade, and including links and a clevis that pivotally move the jaws and their cutting blades into a cutting action upon the horse hooves.

Claims

1. A high pressure, hydraulic hand tool incorporating tool cutting jaws and cutting blades and for use in dense materials cutting applications, said hand tool having a handle, a handle chamber positioned within the handle, a housing integrated at the upper end of the handle, said housing having a piston chamber therein, wherein a piston is slidably located within the piston chamber, and is subject to a high pressure hydraulic fluid motor for urging said piston upwardly and out away from the handle chamber, during a cutting action, but is spring biased downwardly and back toward the handle chamber, for deactivating said blades of the hand tool, after a cut has been made, and wherein a series of links and clevis attached to the upper end of the piston, and are provided for urging the outer back edges of the tool cutting jaws upwardly, and inwardly, for directing the cutting blades into a severing function, and the tool cutting jaws are also pivotally mounted to the upper edge of the housing, to furnish a pivot point about which the jaws pivot, when actuated into a cutting function, said tool cutting jaws are L shaped in configuration, including upwardly extending jaw portions, and integrally laterally extending base portions, the base portions of each tool cutting jaw being pinned together through the usage of a pivot pin, while the lower ends of the upwardly extending law portions are connected by pivot pins to the respective clevis.

3. A method for cutting a dense material comprising providing a high pressure hydraulic hand tool as set forth in either of claim 1 or 2, and applying said tool to said dense material to achieve a cutting effect, wherein said dense material is selected from the group consisting of keratinaceous animal tissue, bone, wire, metal, and a plant tissue.

4. The high pressure hydraulic hand tool as set forth in either of claim 1 or 2, further comprising a safety device for preventing injury to an operator or to an animal to which such device is applied.

5. The high pressure hydraulic hand tool as set forth in claim 4, wherein said safety device is selected from the group consisting of a moisture sensor, sonic means for detecting density, and optical means for detecting electromagnetic variations in materials to which said tool is applied.

6. The high pressure hydraulic hand tool of claim 4 wherein said safety device includes one of a capacitance and a resistance, in contact with the tool jaws of the hand tool which in combination with a microprocessor, can detect the presence of a human touching said jaws to cause a deactivation of the hydraulic motor and prevent further activation of said hand tool.

7. The high pressure hydraulic hand tool of claim 1 wherein said housing includes said piston chamber therein, the upper edge of said piston chamber be beveled, to facilitate the application of the piston therein during assembly.

8. The high pressure hydraulic hand tool of claim 7 wherein said piston includes at least one o-ring to seal the piston within the piston chamber, and to prevent the passage of high pressure hydraulic fluid there past during actuation of the said tool.

9. The high pressure hydraulic hand tool of claim 8 further including at least one oil port provided in the upper region of the housing, for the injection of lubricating fluid therein during usage of the hand tool.

10. The high pressure hydraulic hand tool of claim 1 wherein said handle includes insulation means provided along its exterior length, to insulate a user'"'"'s hand from the tool during application and prevent the activation of a safety device during usage of said tool.

11. The high pressure hydraulic hand tool of claim 1 further including both circuit lines and hydraulic lines connected between a circuit board and the hydraulic motor, respectively, into the handle of the hydraulic hand tool, to provide for the necessary charge for operations of a safety device, and to provide high pressure hydraulic fluid into the piston chamber during actuation of the hand tool during usage.

2. A high pressure, hydraulic hand tool incorporating tool cutting jaws and cutting blades for cutting hooves of horses, including said tool having a handle, a housing integrated at the upper end of the handle, said housing having a piston chamber therein, wherein a piston is slidably located within the piston chamber, and is subject to the high pressure hydraulic fluid for urging it upwardly, during a cutting action, but is spring bias downwardly, for deactivating the tool, after a cut has been made, links and clevis attach to the upper end of the piston, and are provided for urging the outer back edges of the tool cutting jaws upwardly, and inwardly, for directing said cutting blades into a severing function, and the tool cutting jaws are also pivotally mounted to the upper edge of the housing, to furnish a pivot point about which the said cutting jaws pivot, when actuated into a cutting function, said tool cutting jaws are L shaped in configuration, including upwardly extending jaw portions, with integrally laterally extending base portions, the base portions of each tool cutting law being pinned together through the usage of a pivot pin, while the lower ends of the upwardly extending jaw portions are connected by pivot pins to the respective clevis.
