  • Patent number: 8540321
    Abstract: The various embodiments herein provide a system for reducing friction in vehicles operating on agricultural and muddy lands. The system includes a polous placed on a board fastened to the circular base, an arched piece connected one shaft in each of the two hydraulic jacks attached to the board, a plurality of bushings fastened to a wheel ring attached to the polous, a rotating helm attached to one end of a bushing shaft attached to each of the bushings, a guide bar attached to the bushings and bushings shaft and a spring arranged over the guide bar. The movement of the vehicle wheel causes the rotating helm to come in to contact with the arched piece which in turn stroke the bushing shaft resulting in a reciprocal movement inside the bushings thereby providing traction between the vehicle wheel and a land surface.

  • Patent number: 5209050
    Abstract: The present invention relates to the wheel assembly of mowers, particularly to mulching mowers. In the preferred embodiment, each wheel assembly includes a clearing disc sandwiched between a pair of support wheels. The support wheels support the weight of the lawn mower. The clearing disc clears accumulated grass from the wheel assembly by moving between the support wheels as the wheels rotate to clear away grass clippings. The clearing disc has an outside diameter that is greater than the outside diameter of the support wheels and is mounted between the wheels in such a way that the clearing disc continually moves upwardly as the mower is moved.

  • Patent number: 5029945
    Abstract: A traction device including a stationary plate mounted to a housing of an associated drive wheel of a vehicle, with a rotary member mounted rotatably relative to the stationary plate, with spike members mounted relative to the rotary portion extensible upon actuation of an arcuate actuator plate extensible to effect contact, with contact head portions of each spike to effect radial projection of each spike. A medially positioned guide plate includes right and left cam surfaces to effect positioning of each contact head of each spike relative to the actuator plate.

  • Patent number: 4351749
    Abstract: A molecular glass based upon a phosphate of aluminum, or other trivalent metal, provides significant improvement over prior art glasses for encapsulation of high level radioactive nuclear waste. When containing a controlled amount of those elemental oxides found in a typical nuclear waste, the waste-glass would not devitrify under conditions which produced devitrification in the non-nuclear-waste-containing glass, exhibited hydrolysis losses lower by an order of magnitude, had high solvency power for those elemental oxides, exhibited little tendency for internal crystallite formation, and possessed other desirable physical characteristics, all in direct antithesis to the properties of the best prior-known glasses used for this application.

  • Patent number: 4266832
    Abstract: An anti-slip device is operated automatically by a driver from his cab by a hydraulic or manual system. Detachable blades each pivotable around a shaft are disposed on each drive wheel. In order to use the blades they must emerge and project from the peripheral part of the wheel, thus penetrating into the ground. The blades are successively actuated by a roller which rests against a control portion of the blade. The roller is mounted on a lever arm which is moved by a hydraulic jack or by a manual lever system. The blades penetrate the ground and thus prevent the wheel from slipping. In the operating position, the active portion of the blade transmits the penetrating force to the pivot shaft and a stop, i.e. not to the control portion.

  • Patent number: 4154488
    Abstract: A cross-country vehicle includes a wheel provided with an outer layer of resilient material having a plurality of circumferentially disposed protruding teeth. A track is provided about the wheel and has a plurality of transverse bars connected to one another and separated by gaps which engage the protruding teeth. Studs moveably mounted in radial holes through at least some of the teeth of the wheel project downwardly to extend through the gaps and into engagement with the ground.
