  • Patent number: 6789980
    Abstract: A ditch forming apparatus makes the finishing touches on the ground work whereat the ditch is to be formed, pours the concrete, screeds the concrete, and finishes the surface of the concrete. The apparatus uses a hopper with and open top and an open bottom to receive as well as pour the concrete. An extension on the front of the apparatus has a pair of sloped sides joined by a flat bottom making the final shaping of the ground prior to concrete pour. The back edge of the open bottom screeds the concrete while a skid attached to the rear of the apparatus finishes the surface of the poured concrete, the skid having surfaces that are generally parallel with the sides of the extension.

  • Publication number: 20040099212
    Abstract: The present invention provides an apparatus for applying thermoplastic marking material to a pavement surface. The apparatus includes a hopper for holding a supply of particulate thermoplastic marking material in a non-molten state, a means for conveying the thermoplastic marking material from the hopper to a continuous melt processor, and a conduit from the continuous melt processor to a dispenser that directs molten thermoplastic marking material to the pavement surface. The apparatus further includes means for heating the continuous melt processor and conduit to a temperature that is higher than the melt temperature of the thermoplastic marking material. The present invention also provides a method of applying a thermoplastic marking material to a pavement surface.

  • Patent number: 6543961
    Abstract: A device for continuous supply of grouting into joints between longitudinal concrete elements, which are disposed chiefly horizontally next to each other to form, e.g., floors in building constructions. The device comprises a rhombic hopper adapted for displacement along the joint, wherein at least two side walls form an accumulating plow for leading the grouting in towards a vertical plane through the joint. The side walls of the hopper are latitudinally displaceable with respect to each other, and are held with an adjustable force against the surface of the concrete elements. The hopper is arranged below a discharge end of a container, the discharge end having a damper, which is operated by an actuator coupled to a level sensor in the hopper.

  • Patent number: 6517281
    Abstract: A particulate material spreader includes an adjustable spinner apparatus which is incrementally adjustable forwardly and rearwardly to a plurality of operating positions relative to the discharge end of the material conveyor. The adjustment may be manual or automatic to adjust the drop point of the material onto the spinners, thereby accommodating varying application rates of the particulate material on a field, lawn, road, or other area. The spreader may be operatively connected to a microprocessor to receive data input and sensor feedback for variable rate technology.

  • Patent number: 6488443
    Abstract: A pull spreader for spreading a surface material such as asphalt on a path. The pull spreader includes an open-bottomed frame having a first side wall and an opposed second side wall, a front wall extending between the first and second side walls, a screed wall opposed to the front wall and extending between the first and second side walls so that the first and second side walls, front wall and screed wall define a storage chamber for the surface material, wherein the storage chamber has an inlet area defined between top edges of the side walls, front wall and screed wall that is about the same as or smaller than a discharge area of the storage chamber defined between bottom edges of the side walls, front wall and screed wall which bottom edges are adjacent the path over which the pull spreader travels. The pull spreader also includes at least one steering wheel secured to a front frame extension extending from the front wall in a direction away from the storage chamber.
