Wheeled, Load-transporting Type Vehicle Utilizes Its Uninterrupted, Forward Motion To Cause An Externally Supported Load To Be Transferred To It Patents (Class 414/338)
  • Patent number: 8840353
    Abstract: The vehicle mounted highway refuse collector gathers discarded refuse from roadway surfaces at normal highway speeds without slowing down. The refuse collector can gather discarded tire treads, or pieces of furniture, and even dead animals at normal speeds safely. At normal highway speeds, the impact with refuse provides centrifugal force sufficient to gather and rotate debris up and onto a storage shelf allowing the continued operation of the refuse collector until it is full. At less than highway speeds, motor assistance provides the means to gather in, and rotate debris onto the storage shelf safely for operation at slower speeds as in city streets. The cleanout when full is facilitated by pull-pins that drop down the storage shelf so as to be easily unloaded.

  • Publication number: 20140037408
    Abstract: The invention is directed to a material loader for quickly and easily loading material, particularly bulk material, into a containment apparatus. Material to be loaded is placed inside a bin that is dimensioned to fit inside the containment apparatus. In use the containment apparatus is positioned so that the bin is inside the containment apparatus and the containment apparatus or a vehicle bearing the containment apparatus is connected to a material transfer member inside the bin. Forward movement of the containment apparatus/vehicle causes the material transfer member to hold against the material while the bin slides out of the containment apparatus from the point of view of the containment apparatus, leaving the material behind. In other words, the forward movement of the containment apparatus/vehicle causes the material transfer member to pull the material into the containment apparatus. The invention may also be used for unloading a containment apparatus.

  • Publication number: 20130330156
    Abstract: A turf cutter device, an infill extractor/collector device, and a turf wind-up device are used to facilitate the cost-effective removal of an infilled synthetic turf and the subsequent installation of a new turf at the same site, with minimal subsurface disruption. An infill extractor/collector device mounted on a motorized vehicle moves a relatively narrow strip of filled artificial turf from the surface, in front of the vehicle, and directs the strip to an infill removal station. The infill removal station inverts the strip and redirects the strip back toward the front of the vehicle, after agitating the strip to extract the infill. After redirecting the strip toward the front of the vehicle, the vehicle drives over the unfilled strip. Meanwhile, the extractor/collector device moves the extracted infill rearwardly to a bag located in a trailer.

    Abstract: This is a waste collection system from individual homes by use of a divided garbage can, cantilvered from a mobile supporter which is rolled to curbside and secured to in-ground anchors. A divided collecting device (hereafter called "CD") is suspended on the side of a garbage truck. The moving truck passes the CD beneath the can. Both the can and CD have guides to align themselves with one another. The CD has a mechanism that when touched by the can, causes its top to slide open. The CD engages targets that project downward from beneath the can. It pushes the targets and thereby slides the can's bottom open. It simultaneously compresses a spring beneath the can. Garbage falls from both compartments of the can onto the divided CD. The truck continues to move, the targets disengage, the compressed spring is released and closes the bottom of the can. The top of the CD closes and a sweeper inside the CD stradling the divider rams the garbage backward onto a closed pan.

  • Patent number: 4946328
    Abstract: These loaders for transfer of cargo containers or semitrailers to and from railway cars etc. have parallel swinging links vertically connecting the load-spreader support end of the lift arm with the end of the arm which is mounted to a pivot. The links are free to swing back when the loadspreader engages a vehicle to cushion and carry the load-spreader aligned with the vehicle for transfer across the chord of a transfer arc. A weight extends the links out at the bottom to extend the loadspreader to swing back through vertical for least change in elevation. The load arm is supported on wheels to run on the cam track at or near the same elevation that is mounted to swing up and down on the mount about the pivot, so the cam track wheels run on a substantially uniform radius from the pivot. The inner end of the arm extends up to support the top ends of the swinging links which depend to support the outer end of the arm or vice versa.

    Abstract: A bottom discharge hopper rail car has a hopper body mounted on a chassis which is itself supported on flanged wheels. The body has a pair of downwardly converging, laterally spaced side walls with longitudinally extending lower edges which border a discharge opening. The spacing between the lower edges of the sidewalls is greater than the lateral distance between the wheels as wider openings can facilitate discharge. In practice, the wheels have outer flange surfaces adjacent to rail-engaging surfaces for resting on the rails, and the spacing between the lower edges of the side walls is preferably greater than the distance between these outer flange surfaces. The side walls are asymmetrical with respect to a longitudinal vertical plane passing centrally between the wheels as this can inhibit bridging during discharge.

    Abstract: A load-transporting method and apparatus involve use of a transport vehicle, preferably a straddle truck, having connected thereto a load carrier in the form of a frame which is capable of engaging a load and elevating the same with respect to a given surface on which the load initially rests when the load-carrier is raised with respect to this surface. The connection between the load carrier and the vehicle is such that once the load is engaged by the load carrier, the travel of the vehicle with respect to the load causes the load carrier to act through its connection to the vehicle on the latter in a manner which resists the travel of the vehicle and causes the load to move frictionally with respect to the above surface on which it initially rests, the kinetic energy of the travelling vehicle and the friction of the load with respect to the surface and/or the inertia of the load being utilized to bring about elevation of the load and the load-carrier with respect to the above surface.
