  • Patent number: 7544011
    Abstract: An apparatus for regulating a flow of pavement rejuvenation materials for deposit on a roadway is disclosed in one aspect of the invention as including a first channel is supported by a pavement recycling machine and is in communication with a supply of pavement rejuvenation materials; a second channel slideably coupled to the first channel, the pavement rejuvenation materials adapted to flow through the first and second channels; and a hardened tip coupled to the second channel. The apparatus may also have a seat coupled to one of the channels; and a blocking element coupled to the other of the channels. Upon sliding the first channel with respect to the second channel, the blocking element contacts the seat, thereby impeding the flow of pavement rejuvenation materials flowing through the channels.

  • Patent number: 5988939
    Abstract: A vibration system that fits on top of a conventional truss with minimal alteration. The system comprises a propulsion assembly powering a vibration assembly. The propulsion assembly comprises two parallel rails forming a lateral path between truss ends and supporting a mobile carriage. Each rail comprises abutting segments coextensively surmounting the truss. Each segment attaches at respective truss cross-beams to define a continuous runway for carriage movement. Each segment also defines a channel for a chain rack anchored at opposite truss ends. The carriage comprises an undercarriage supporting an offset platform. The undercarriage comprises a rail-spanning frame with supporting runway tracking wheels. A motor propels the carriage by turning an axle with terminal pinions entrained about the rack. The offset counterbalances the vibration assembly to reduce torsion. A coupling hitch protrudes from the platform opposite the offset to support the vibration assembly.

  • Patent number: 5462388
    Abstract: A vibrator for compacting construction materials has a housing having a housing mantle with a first end face and a cylindrical interior. The housing has an upper part for closing the housing at the first end face. The upper part is axially inserted into the housing mantle and secured in a closing position thereof against axial displacement. A radially inwardly extending support surface is connected within the housing mantle. An electric motor is drivingly connected to an unbalanced shaft. The electric motor has an inner rotor end an outer cylindrical stator pack end is inserted into the housing mantle from the first end face. The stator pack has a recess and is inserted into the housing mantle with sliding fit and secured against rotation. A spreading element made of spring steel for securing the stator pack is inserted into the housing mantle through the first end face and positioned on the stator pack before closing the housing to be clamped between the support surface and the upper housing part.

  • Patent number: 4678364
    Abstract: A forming tool made to be drawn by tractor-feeder means of any type. The tool comprises two arms mounted to pivot by their front ends on the tractor-feeder. At the back end of the arms is mounted a needle ramp for immersion vibration so as to keep the concrete delivered and distributed by the tractor-feeder in the liquid state before its forming. The forming means comprise an upper element which has a front part in the form of a shield for the regulation of the amount of concrete introduced under the form, and a back part serving as forming upper plate and simultaneously as back reference and support means for levelling the tool, the latter being entirely carried by the formed concrete layer. Side forming plates are also provided.

  • Patent number: 4343568
    Abstract: The road grading and tamping appliance (1) has a bottom plate (2) and at least one rotating, eccentrically-supported and driven weight for providing vibration. The bottom plate (2) is provided with a shaft (5) disposed perpendicular thereto and on which the rotating eccentric weight (10) is rotatably supported, specifically at a predetermined distance from the bottom plate (2). The eccentric weight (10) consequently rotates in a plane parallel to the bottom plate. By adjustment of the rotating eccentric weight (10) axially of the vertical shaft (5), the eccentric action, that is the leverage action, on the bottom plate (2) can be reduced or increased.

  • Patent number: 4314773
    Abstract: A high density concrete placer is longitudinally translatable along a pair of parallel oriented support rails positioned adjacent to an area in which wet concrete has been poured. The concrete placer includes a bridge having first and second ends and first and second roller assemblies coupled to the first and second ends of the bridge. The roller assemblies contact the support rails and enable the bridge to be longitudinally translated along the support rails. A frame includes a plurality of immersible vibrator units which are coupled at spaced apart intervals along one side of the frame and descend vertically downward therefrom. A rolling table is coupled to the bridge and to the frame to be laterally translated between the first and second ends of the bridge. The frame includes a subframe which is vertically displaceable between a first and a second position and serves to vertically displace the vibrator units between a first and a second position.
