  • Ground-engaging tool inserts with angled edges
    Patent number: 4128132
    Abstract: A wear-resistant alloy is inlaid in a channel along the undersurface of a cutting edge of a ground-engaging implement. The wear-resistant alloy is in the form of individual blocks which are brazed within the channel. The joints between contiguous blocks are non-parallel to the general direction of travel of the ground-engaging implement for improved tool wear.
    Type: Grant
    Filed: September 1, 1977
    Date of Patent: December 5, 1978
    Assignee: Caterpillar Tractor Co.
    Inventors: Lowell J. Moen, Harris S. Olson
  • Composite wear-resistant alloy, and tools from same
    Patent number: 4113920
    Abstract: Spheroidal particles of wear-resistant alloy comprising boron, chromium and iron having maximum hardness for a given composition are produced by the rapid cooling of a molten alloy mixture. The resultant solid particles are then incorporated into a composite alloy wherein the solid particles are held together with a matrix of different material from the alloy. Inserts of the composite wear-resistant alloy are useful in producing long wearing tools.
    Type: Grant

    Date of Patent: September 12, 1978
    Assignee: Caterpillar Tractor Co.
    Inventors: Eugene L. Helton, Preston L. Gale, Lowell J. Moen, Robert C. Mueller, Walker L. Pierce, Jr., Henry J. Vermillion, Jr.
  • Wear-resistant composite material and method of making an article thereof
    Patent number: 4066422
    Abstract: A wear-resistant composite material and method of making an article thereof is disclosed which is particularly adaptable for use with a ground-engaging tool. The composite material has a plurality of abrasive-resistant particles embedded in an iron-boron matrix.

  • Ground-engaging tool with wear-resistant insert
    Patent number: 4052802
    Abstract: A ground-engaging tool is disclosed which includes a blade with a load carrying front face, a ground-engaging bottom surface, and a rear face, and a wear-resistant insert is secured thereto to extend the service life thereof. The wear-resistant insert includes a back-up plate which is disposed in rearwardly spaced relation from the rear face of the blade and adjacent its bottom surface, a wear-resistant material which is bondably sandwiched between the plate and the rear face, and a plurality of bridging members which extend through the wear-resistant material and are rigidly secured to the plate and the rear face of the blade to minimize in use spalling of the wear-resistant material.
