Patent number: 4113920Abstract: 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: GrantFiled: October 18, 1976Date of Patent: September 12, 1978Assignee: Caterpillar Tractor Co.Inventors: Eugene L. Helton, Preston L. Gale, Lowell J. Moen, Robert C. Mueller, Walker L. Pierce, Jr., Henry J. Vermillion, Jr.

Patent number: 4096653Abstract: An earthworking device comprises a support member having a work tool, such as an earthworking tip, detachably mounted on a forward end thereof. A pin is disposed in aligned bores formed through the support member and the work tool and an annular replaceable cartridge circumvents the pin to retain it in position. The cartridge comprises a housing having an annular elastomeric member secured therein and circumventing the pin in frictional engagement therewith.Type: GrantFiled: October 31, 1974Date of Patent: June 27, 1978Assignee: Caterpillar Tractor Co.Inventors: Willard Oswald Kaarlela, Eugene L. Helton

Patent number: 4088429Abstract: A shot producing machine includes a rotatable vessel containing molten metal, the rotation of such vessel throwing the molten metal therefrom in the form of spherical droplets. The spherical droplets are caused to pass through a liquid spray whereby they are solidified into pellets, and thereafter fall to the bottom of a receiving vessel for collection.Type: GrantFiled: July 20, 1977Date of Patent: May 9, 1978Assignee: Caterpillar Tractor Co.Inventors: Eugene L. Helton, Gerald P. Simmons

Patent number: 4052802Abstract: 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.Type: GrantFiled: February 23, 1976Date of Patent: October 11, 1977Assignee: Caterpillar Tractor Co.Inventors: Lowell J. Moen, Eugene L. Helton, Chris R. Straesser

Patent number: 3990162Abstract: An earthworking device comprises an adapter having a tip detachably mounted on a forward end thereof. A flat pin of rectangular cross section, disposed in aligned bores formed through the adapter and the tip, is held in place by a triangularly shaped spring clip which straddles notches formed on the pin.Type: GrantFiled: October 1, 1974Date of Patent: November 9, 1976Assignee: Caterpillar Tractor Co.Inventors: Lloyd K. Heinold, Eugene L. Helton

Patent number: 3984910Abstract: A multi-material earthworking ripper tip having a leading nose portion comprised of a material having greater wear resistance and strength at elevated temperatures than the material which comprises the rearward shank supporting portion of the tip. In one embodiment, a bi-metallic nose portion is inertial welded to the shank support portion of the tip. In another embodiment powdered tungsten carbide is sintered in situ within a hollow bore of a steel nose portion. Alternately, a solid core of tungsten carbide could be soldered, brazed or press fitted within said hollow bore.Type: GrantFiled: September 8, 1975Date of Patent: October 12, 1976Assignee: Caterpillar Tractor Co.Inventors: Eugene L. Helton, Walter B. Miller

Patent number: 3970445Abstract: A wear-resistant alloy comprising boron, chromium and iron having maximum hardness for a given composition is produced by rapidly cooling and solidfying spheroidal particles of the molten alloy mixture. The resultant solid particles are then cast in the desired form, or incorporated into a composite alloy wherein the solid particles are held together with a matrix of different material from the alloy.Type: GrantFiled: May 2, 1974Date of Patent: July 20, 1976Assignee: Caterpillar Tractor Co.Inventors: Preston L. Gale, Eugene L. Helton, Robert C. Mueller

Patent number: 3961788Abstract: A bulldozer blade comprises an upright member having a pair of laterally spaced end plates and a transversely disposed cutting edge secured thereon. A mounting plate is secured forwardly on the outboard side of each of the end plates and an adapter is secured forwardly on each of the mounting plates. An end bit and an earthworking tip are detachably mounted on each of the adapters.Type: GrantFiled: February 7, 1975Date of Patent: June 8, 1976Assignee: Caterpillar Tractor Co.Inventors: Eugene L. Helton, Nathan Gutman, Donald E. Ribbing

Patent number: 3952433Abstract: An earthworking device comprises a support member having a work tool, such as an earthworking tip, detachably mounted on a forward end thereof. A pin is disposed in aligned bores formed through the support member and the work tool and a spring clip straddles the pin in locked engagement therewith. The spring clip is substantially encapsulated by an elastomeric member which aids in maintaining the spring clip in frictional engagement with the pin. The spring clip may comprise a "hair pin" or U-shaped configuration.Type: GrantFiled: September 3, 1974Date of Patent: April 27, 1976Assignee: Caterpillar Tractor Co.Inventors: Lloyd K. Heinold, Eugene L. Helton, Donald J. Larson
