Trimming And Bur Removing Patents (Class 59/59)
  • Patent number: 8820043
    Abstract: A method for cold manufacturing horseshoes utilizes a laser cutter, a hydraulic press, and a sanding belt to cut horseshoes from a sheet of material without heating up the sheet of material. Information, including dimensions of the horseshoe as well as position and size of a plurality of nail holes, is fed into a control computer for the laser cutter. The laser cutter cuts an outline of the horseshoe from the sheet of material, as directed by the control computer. The laser cutter also creates nail outlines, providing a guide for the second step involving the hydraulic press. Once the nail outlines are created an appropriately sized punch is selected for the hydraulic press. The hydraulic press uses the punch to bore through the outlines, creating beveled nail holes. The horseshoe is then moved to a sanding belt, where a rear surface and edge of the horseshoe is sanded smooth.

  • Patent number: 4910955
    Abstract: A horseshoe trimming device for securement to a farrier's anvil has a base provided with a downwardly extending rectangular post dimensioned for insertion into a rectangular socket on the farrier's anvil. A clamp screw clamps a portion of the anvil against the rectangular post. An anvil plate is secured to an adjustment plate which is pivotally mounted on an upper surface of the base. Opposed set screws bear against opposite side edges of the adjustment plate for adjusting the attached anvil plate in opposite rotational directions. By tightening a pivotal mounting bolt extending through the adjustment plate, the attached anvil plate may be secured in a selected adjusted position. The anvil plate has an arcuate edge dimensioned for cooperation with the arcuate cutting edge of a shear blade to trim end portions of a horseshoe. The arcuate shear blade has an elongated rectangular shank received within a rectangular guide tube for vertical reciprocal movement.
