Abstract
Abstract The invention has hoist means to elevate or lower Panels, such as sheetrock, wall board and plywood and the like, and, exactly place and fit panels of same on the ceilings of rooms in a building. The hoist means is supported on a platform having rollers thereunder to facilitate moving the same about on the floor opposite the ceiling in a room. On top of activated hoist post is an I-frame on top of which is a slidable sliding frame both lengthwise and sidewise activated by rope means wound around a drum whereby said sliding frame may be shifted lengthwise on said I-frame, and, other rope means wound around said drum after freeing the first named rope means from said drum whereby said H-frame is slidable sidewise over said I-frame. The lengthwise and sidewise movement of said sliding frame with panel on top of said H-frame enables the operator to precisely fit one panel after another in juxta position to each other on the ceiling for affixing and nailing said panels to said ceiling of a room quickly and in a more facile way than has ever been done before.
