  • Patent number: 5747074
    Abstract: Apparatus for the manufacturing of prestressed reinforced concrete railroad ties and the like in which the apparatus consists of an elongated spine or compression member which has no foundation but rather is independent of the supporting surface upon which it rests. In one version of the apparatus two bridge members confront the opposite ends of the spine and permanent tension resisting members pass beneath the spine from end to end of the spine and are attached to the lower ends of the bridge members. In another version two structural members are embedded in the concrete of the spine and protrude to provide terminal members.

  • Patent number: 5735063
    Abstract: A skishoe having a central, downwardly concave arch portion, an upwardly concave toe portion, an upwardly concave heel portion, and a snow gripping blade. The snow gripping blade is pivotable about an axis lying within the camber of the arch portion and extending transversely of the skishoe. A first adjustable stop is provided for limiting the angular deflection of the gripper blade from its fully retracted position in the camber. A second adjustable blade stop is provided for limiting the retraction of the blade into the camber, and a spring is provided for resiliently biasing the blade toward the first adjustable blade stop. Electric drive motors are provided for selectively positioning said stops. Manually operated control means, attached to the body of the user, are provided for controlling said electric drive motors.

  • Patent number: 5568709
    Abstract: Simulated decorative architectural columns comprising an axial member and a jacket surrounding the axial member. The jacket is comprised of a plurality of elongated rigid foam material members of truncated wedge-shaped cross-section, or jacket wedges. After the jacket is assembled around the axial member the outer surface of the jacket is sanded to provide a smooth surface, and the smooth surface is provided with an overcoating resembling a cut surface of stone. Groups of jacket wedges are fabricated from corresponding blanks by means of a hot-wire foam cutting machine. Each blank is first subdivided into a lower portion and an upper portion by a parting surface the profile of which is substantially identical to the intended profile of the finished column. The lower or relievo portion of the blank is then subdivided into a plurality of wedge members by a series of oblique cuts each extending from end to end of the lower portion of the blank.
