  • Patent number: 8616310
    Abstract: The instant invention is an electric machine/tractor particularly intended for farming, gardening and landscaping and is nonpolluting and self charging. The tractor accommodates standard farm implements and can supply electrical power to remote areas. To achieve these goals, the machine is comprised of a frame and wheels which are driven independently by hydraulic motors powered by a variable volume, hydrostatic pump that is driven in line, by an electric motor that also drives a hydraulic lift pump and a power-take-off shaft through belts. The hydrostatic pump is controlled by the operator for forward and reverse motion. The electric motor is powered by batteries and the batteries can be recharged by an on-board photoelectric panel. A combination charger/inverter is located aboard the tractor to charge the batteries from any 110V A.C. power outlet or generate 110V A.C. electrical power from the tractor.

    Abstract: A rotary broom mounts upon a slotted plate that pivots upon a double gearbox. The broom has bristles upon an axle within a shield that receives power from a chain drive that receives its power from a driveline from a top gear box. The top gearbox orients in the direction of the chain driveline and delivers its power through an output shaft. The top gearbox joins to a slotted plate that turns in the same direction as the broom. The top gear box receives its power through an input shaft perpendicular to the output shaft. The top gearbox input shaft extends downwardly and becomes the output shaft of the bottom gearbox. The bottom gearbox has an input shaft that connects to a power take off. This rotary broom receives rotational power, rotates it 90° upwardly, then rotates it 90° downwardly and at an angle laterally to drive the broom.

  • Patent number: 7798158
    Abstract: Disclosed is a cleaning system for removing coatings from a hard surface by high pressure liquid. The system employs a combination liquid and vacuum reservoir connected to a high pressure pump for directing ultra high pressure water through a blast head mounted on a front portion of the vehicle. The cleaning system is preferably mounted on a single truck with a single prime mover. The drive-line of the vehicle is constructed and arranged to operate in two distinct modes, e.g. a transport mode and a work mode. In the transport mode, a first transmission coupled to the rear portion of the prime mover delivers torque from the engine to the rear wheels of the vehicle. In the work mode, the prime mover is utilized to mechanically drive the bed mounted equipment as well as provide motive force in the form of mechanical-hydrostatic transmission to propel the system at a speed suitable for marking removal.
