  • Patent number: 6059257
    Abstract: A universal bracket holds an object in place on the inside surface of a mold frame while settable material in a fluid state is poured into the frame and allowed to harden so that thereafter the frame and bracket can be removed to produce a fixed structure in the shape of the frame with the object embedded on the face of the fixed structure. The universal bracket has a plurality of wall members interconnected to form a shape corresponding to the outline of the object to be held by the bracket. Each wall member has an inside lateral continuous surface for engaging an outside lateral surface of the object. Each wall member also has an outside lateral continuous surface with an alternate pattern of lands and slots. The alternate pattern begins with a land at one end of the wall member and ends with a slot at the other end of the wall member. The land end of each wall member is adjacent to the slot end of the adjacent wall member of the bracket.

  • Patent number: 5976442
    Abstract: A method and assembly (20) to form a cast concrete panel (21). The assembly (20) has end beams between which tendons (23) can pass. The beams need to be able to support tensioning of the tendons. Transversely extending form members (25) cooperate with form members (27) to enclose a space to receive concrete to form the panel (21). The tendons (23) pass through the space.

  • Patent number: 5954261
    Abstract: A mold for joining conductors such as stranded cable to each other and to other elements such as a ground rod is formed of two or more parts. The mold formed by the parts includes a weld chamber. Exothermic welding material in a crucible above forms molten metal which drops into the weld chamber through a tap hole. The mold includes sleeving passages extending upwardly at an angle from horizontal to exit the mold well above the level of molten metal forming the weld. The sleeving passages extending upwardly at an angle from the weld chamber, or as a V with two symmetrical passages, are preferably larger than normal passages and accordingly will accommodate a wide variety of cable sizes without interference with or abrasion of the sleeving passages. This enables one mold to accommodate more sizes, avoids the use of packing, adapter sleeves or shims, and maintains the weld chamber well vented.

  • Patent number: 5900180
    Abstract: A disposable object form line for use in horizontal casting of building panels from settable material in which at least one side has an exposed face of embedded objects. The object form liner is comprised of a thin support sheet having an adhesive coating on one side. A closed cell plastic grid having ridges which define openings sized to fit the outer perimeter of the intended objects is provided. The grid is adhered to the adhesive coating on the support sheet. Retarder strips may be inserted in each opening to prevent contamination of the face of the object during the pouring process. The form liner is placed in the bottom of a horizontal mold. The objects, such as bricks, are positioned in the openings provided in the layout form liner and the settable material is poured into the mold to form a construction panel. After setting, the panel and disposable form liner are removed from the mold and the liner is stripped from the panel to expose the objects embedded in the surface.

  • Patent number: 5715886
    Abstract: The mold includes a refractory body forming a weld chamber. Exothermic welding material in a crucible above forms molten metal which drops into the weld chamber through a tap hole or open top. The mold includes sleeving passages formed by projecting metal guide tubes extending upwardly at an angle from horizontal to a position above the level of molten metal forming the weld. In this manner, the molten metal is contained within the weld cavity of the mold without packing, adapter sleeves or shims. The guides extend upwardly at an angle from the weld chamber, or as a V with two symmetrical guides. The inside diameters of the guides are larger than normal passages and accordingly accommodate a wide variety of cable sizes without interference with or abrasion of the sleeving passages. This enables one mold to accommodate more sizes, avoids the use of packing, adapter sleeves or shims, and maintains the weld chamber well vented.

  • Patent number: 5716539
    Abstract: An insert is described for attachment to a concrete railroad tie mold within an opening formed therein. The insert is adapted to releasably receive and position a railroad rail fastener with a head end positioned below the mold and an anchor part projecting into the mold. The insert includes an insert body including an outward peripheral edge surface shaped to fit within the formed first opening in the railroad tie mold, and an internal peripheral edge surface defining a fastener receiving opening, situated inwardly of the outward peripheral edge surface. The insert body further includes a top surface that is held in substantial coplanar relation to an adjacent mold bottom surface. A clip arrangement provided on the insert body functions to releasably secure the insert body to the mold with the top surface of the insert body being substantially coplanar with the bottom mold wall. An adapter may be provided on the mold to facilitate mounting and positioning of the insert on the mold.

  • Patent number: 5647425
    Abstract: A mold assembly and method for lap welding a conductor to a vertical bar or rod features two vertically split mold parts having a major parting surface in which are formed a crucible, tap hole, sleeving for the conductor and a weld chamber. An offset parting surface forms a sleeving passage for the vertical bar or rod, and a portion of the weld chamber. The offset parting surface is formed in an interfitting tongue and groove which assists in the assembly of the mold parts.

  • Patent number: 5582228
    Abstract: An exothermic welding apparatus and method uses a crucible which can be used with a variety of exothermic weld metal material volumes to produce welds of different sizes while maintaining the desired diameter to height ratio for each volume of exothermic material. In one embodiment, the crucible includes a double or two stage cavity. The crucible includes a somewhat smaller lower stage which reduces the diameter for smaller volumes. This lower stage may have two disk seats to isolate the two stages from the tap hole. A disk seat is provided for a larger disk between the two stages. The crucible may include a volume of exothermic material in the smaller lower chamber, the larger upper chamber, or a combination of both. In a triple stage embodiment, a wider variety of exothermic material volumes or masses may be accommodated, all while maintaining the desired diameter to height ratio for each charge. Although the desired ratio is approximately one, the ratio range should be maintained from about 0.5 to about 1.

    Abstract: Apparatus and method for constructing a manhole collar between an existing manhole cone and a precast manhole ring. The apparatus includes a circular slip form tube, tapered from a larger top diameter to a smaller bottom diameter; at least two support arms, radially extending from adjacent the top of the slip form tube for placement on a support surface, such as a road surface, to hold the tube at a selected height relative to ground level within a manhole cone; and a plurality of fasteners for attachment of a precast manhole ring about the exterior periphery of the slip form tube for supporting the ring at a selected height relative to the manhole cone and the roadway surface. The apparatus may include a concrete spill retention ring, placeable upon the top rim of the manhole cone and around the slip form tube to prevent concrete from entering the manhole cone.
