    Abstract: A paver for laying down a strip of concrete and inserting therein dowel bars parallel to the strip. A dowel bar inserter orients the bars and places them into the concrete. A pair of transport chains transverse to the travel direction extends across a width of the inserter. Pairs of generally L-shaped opposing cups hold the bars so that they can drop downwardly from the cups towards the strip. The chains move in a single direction. A dowel bar holding magazine, above the chains, stores bars, and gravitationally moves the bars towards the chains for pick-up by cups as the chains move the cups past a bar loading station. Elastic bands extend about a bar engaging surface defined by a wheel and resiliently bias the bars moving along the chain turn-around section against the wheel.

    Abstract: A device indicates the level of concrete within the hopper of a concrete pump and prevent accidental overflow and spills. The concrete level indicator device includes an elongate post with an enlarge float fixed to the bottom end and a guide sleeve for allowing vertical telescoping movement of the post as the concrete level in this hopper changes. A retaining collar attaches to a screen in the hopper of the pump and surrounds the guide sleeve for limiting swinging movement of the post and guide sleeve, thereby maintaining the device in a vertical position within the hopper with the float resting on the concrete. As concrete is filled into the hopper, the post rises through the guide sleeve until a visual indicator (e.g. a red band) on the top end of the post is visibly exposed above the guide sleeve, thereby alerting the operator to interrupt the discharge of concrete being filled in the hopper until the concrete level drops and the visible indicator on the post is no longer visible.

  • Patent number: 5405212
    Abstract: A paving machine having a medially located dowel bar feeder positioned in front of a dowel bar inserter. The machine has a screw or paddle for spreading the concrete and a front strike-off to allocate a proper amount of unconsolidated concrete beneath the machine. Next in line, internal vibrators are mounted to the machine to perform a preliminary consolidation of the concrete, followed by a screed to meter out a correct volume of consolidated concrete for a finished concrete slab. To the rear of the screed, the dowel bar feeder drops dowel bars in a predetermined pattern on the top surface of the consolidated concrete. The dowel bar inserted is mounted to the paving machine behind the dowel bar feeder and includes a plurality of vibrating forks which descend to engage the dropped dowel bars and insert the dowels into the unhardened concrete. In operation, the dowel bars are dropped and the paving machine is driven forward until the forks are over the dropped dowel bars.

  • Patent number: 5372372
    Abstract: A cart and a method of using the cart for tying steel rods, which cart includes a substantially rectangular frame supporting front and rear rollers. The rollers are in the form of cylinders having a substantial width which is much greater than the largest anticipated spacing between parallel reinforcement rods. The use of the cylinders as rollers allows the cart to travel upon the uppermost layer or set of reinforcing rods without becoming entangled in the lattice of reinforcing rods. A cushioned seat may be located on the frame adjacent an open area extending through the frame. The worker may support herself or himself upon this cushioned portion while the open area provides access to the lattice for tying the rods together. Vertical bars may support an alternate cushion at a position spaced upwardly from the reinforcing rods. The user may then rest his or her stomach or chest upon this upper cushion and lie in a faced down configuration with the reinforcing rods at arms length.

    Abstract: A dowel setting device which can be employed together with a formless paving machine is described. A plurality of booms is pivotably disposed, looking in the direction of travel, ahead of the vehicle body and ahead of devices for tamping the concrete. Dowel retrievers are located at the ends of the booms. In a loading position, the dowel retrievers retrieve dowels from a magazine. Following a pivot movement, the dowel retrievers assume a setting position in which they extend, looking in the direction of travel, from the front into the area where the concrete is beginning to set. The dowels are ejected.

  • Patent number: 5135333
    Abstract: An apparatus and process for the placement of horizontally disposed side by side and/or vertically staggered reinforcing bands in combination with a typical slip form or form type concrete paver. The paver receives and spreads fresh concrete, continuously dispences reinforcing bands, then levels, holds, liquifies and finishes the concrete in a single pass. A plurality of inserters which dispense the bands are lined across the width of the apparatus and may be staggered inserters to enhance concrete flow around them. They are threaded with the reinforcement and move through unconsolidated concrete positioned between the leveler and the form.

    Abstract: An apparatus for lining a canal is described as well as the method for lining the canal. The apparatus comprises an elongated frame which extends transversely across the canal and which is propelled the length thereof. A concrete paver is supported on the frame and is designed to lay concrete on one of the sides of the canal and at least a portion of the bottom of the canal as the frame is moved along the length of the canal. A flexible sheet material is positioned on the canal sides and bottom just prior to the concrete being positioned thereon. The PVC is positioned on the canal in a substantially wrinkle-free and untensioned condition. The method of lining the canal is also described.

  • Patent number: 4828432
    Abstract: Apparatus for lining an irrigation canal with a sheet of fiber-reinforced plastic includes structure for depositing a layer of resin and fiber on a web of flexible carrier material, partially curing the resin prior to laying the sheet in the canal, and then laying the sheet in the canal while the resin is flexible enough to conform to the shape of the canal. The final curing of the resin takes place after the sheet is placed in the canal. A predetermined-shape wrinkle is induced in the carrier web before it is laid into the canal to assist in conforming the sheet to the canal shape without causing randomly placed wrinkles so that the sheet is smooth in the canal. The apparatus forms the sheet and is propelled so that it travels along the length of the canal, fabricating a continuous sheet as it travels. In one embodiment the carrier is a flexible but nonelastic material like kraft paper, coated on one side with wax or other film to prevent saturation by the resin.

  • Patent number: 4798495
    Abstract: The apparatus (20) is vertically and adjustably placed on the girders (2b) of the sheet piling equipment (1). It has a slab (21) with apertures (26) parallel to the direction of movement. A vibrating beam (60) is vertically and adjustably placed on the slab (21) between two supports (51, 52). Fasteners (28) are arranged on the apertures (26) for the reinforcement rods (22). The (60) beam is lowered by means of prongs (62). The prongs (62) surround the reinforcement rods (22) and ease them into the road surface (6). After lifting the beam (60) with the prongs (62), the slab (21) is moved back and forth horizontally to the apertures (26), then lifted and pulled back up to the equipment (1). Thus, any irregularities caused by installation of reinforcement rods (22) can be eliminated.

  • Patent number: 4793731
    Abstract: A truck having a road oil spreader is equipped with an apparatus for simultaneous application of oil and paving fabric to the road surface. The apparatus includes an assembly for engaging a roll of paving fabric comprising adjustable cone arms mounted on end plates that rotatably hold the core of the fabric roll. The fabric is drawn over a guide shaft and beneath a sectioned box beam having a series of longitudinally aligned brushes. The shaft and brushes are connected to the opposing end plates which are attached to a lateral support beam. The end plates and box beam include joint, drive and connection means that permit longitudinal, vertical and angular adjustment of the guide shaft and brushes. As oil is sprayed over the road surface, the fabric unrolls and becomes embedded in the oil by action of the brushes pushing the fabric into the oil-coated surface.
