  • Patent number: 4253256
    Abstract: An improved reciprocatory self-loading dual-ended earth excavation vehicle pivotally connected to two or more unmanned self-leveling and self-maneuvering telescopic conveyor vehicles, the latter in turn are pivotally connected to a multi-function dual-ended distribution vehicle capable of conveying, spreading, wetting, impacting and grading the earth fill. The above-mentioned articulated vehicles provide the means to excavate, convey and discharge a virtually continuous flow of earth while traveling in a forward or rearward direction. The excavation and telescopic conveyor vehicles are readily adaptable to surface mining of various minerals including coal and oil shale by simply exchanging the above-mentioned distribution vehicle for a pivotally connected boom conveyer vehicle which provides the means for discharging the ore at a mill site or for the loading of long haul ore carriers.

  • Patent number: 4219210
    Abstract: An auxiliary trailer for towing behind a tractor and main trailer combination adapted to carry an elongated self supporting load. A forward end of the load is carried on a bunk on the tractor, and the bunk that normally supports the aft end of the load is removed and fitted on a turntable of the auxiliary trailer. A lower portion of the turntable fitted on the main trailer receives a complementary forward portion of the auxiliary trailer and the load now extends between bunks fitted on the tractor and the auxiliary trailer, the main trailer serving merely to support a forward end of the auxiliary trailer and to transmit turning forces to the auxiliary trailer. In this manner, the number of load bearing axles and spacing between the axles is increased, thus increasing capacity of the vehicle. Normal onboard load measuring gear is adaptable to indicate vehicle load. Equivalent structure for coupling the auxiliary trailer to the main trailer can be substituted for the turntables.

Adjacent marginal portions of the hitch sections are pivotally connected and the first wing sections may be swung upwardly into upstanding positions overlying the adjacent sides of the center section. The second wing sections are swingable upwardly and inwardly into inverted superposed positions over the first wing sections and the third wing sections are swingable into juxtaposition with the second sections and the undersides of the second and third sections opposing each other. The fourth sections are swingable into inverted superposed positions relative to the third sections and the fifth wing sections are swingable into juxtaposition with the fourth sections and the undersides of the fourth and fifth sections opposing each other.

  • Patent number: 4078821
    Abstract: A utility trailer for towing behind a vehicle, for uses such as carrying a motorcycle. The frame is rectangular and comprised of tubular members, with longitudinal channels on top of the tubular members for receiving motorcycle wheels. A detachable castor wheel supports the frame and is connected to it by means of leaf springs attached to the wheel on opposite sides. Two hitches for connecting the trailer to a vehicle are spaced apart on the forward end of the frame. Each hitch has two tabs, one connected to the vehicle and one to the frame that are coupled together by a pin. The hitch portion that is connected to the frame is L-shaped so that it can be inverted to change the height for different vehicle sizes. The mounting system for securing motorcycles includes a pair of telescoping tubes that are threaded together so that their combined length may be varied.
