  • Publication number: 20140374678
    Abstract: A leverage bar for manipulating formwork panels is used to provide a mechanical advantage for aligning heavy formwork panels before clamping. A pin support plate is connected to one end of an elongated bar. A pair of cylindrical pins is connected to the pin support plate, and a third pin is connected to the elongated bar opposite the first and second pin. The pins are inserted into pre-existing holes in the formwork panels and torque is applied to the elongated bar by a worker at the end opposite the pins in order to leverage the panels into place.

  • Patent number: 5855219
    Abstract: A bottle washing apparatus for effectively washing the inside of bottles that are coated with solid particulate residue. The apparatus includes a fixed portion that connects to a conventional faucet and an elongated closed ended hollow shaft that is provided with a plurality of small orifices. A second closed ended hollow shaft concentrically overlies the first shaft and is rotationally affixed thereto. The second shaft is provided with a plurality of smaller orifices that are tangential with the circumference of the shaft so that when water pressure is applied to the fixed portion, water passes through the orifices in the first shaft and then through the tangential orifices of the second shaft causing the second shaft to rotate at a high rate of speed while discharging the water in needle-like streams under high pressure.

  • Patent number: 4949462
    Abstract: A drywall cutting device that includes a channel-shaped sleeve for slidably mounted disposition on a stem of a T-square at predetermined selectable positions. A handle operated clamping device is mounted on and secured with the channel-shaped sleeve for retaining the sleeve in a predetermined selected fixed position on the stem of a T-square. The device includes a handle projecting above the sleeve for overlying a T-square. A knife holder is joined with the sleeve, and a knife is adjustably secured with the knife holder at right angles to the channel for cutting a line perpendicular to the stem of the T-square when the clamping device and the T-square are drawn together across a surface to be cut.
