  • Drywall board construction
    Patent number: 4397123
    Abstract: An improved construction for a horizontally installed drywall board incorporates widthwise extending tear-off strips on the back side of each butt end. When the butt ends of two boards are mated for nailing to a stud, the strips are removed which allows the butt ends to bend at the join line to form a depression for receiving the finishing joint cement. A pair of relatively short lengthwise extending tapered tear strips are also provided on opposite corners adjacent one edge of the board and which are also removed to facilitate continuation of the depression along the join line when the board edges are nailed to a stud plate adjacent the ceiling or floor of the room being covered by the wallboard. An alternative embodiment utilizes a tapered construction on the butt ends on the back face of the board and a convention tapered construction on the outer face of the board along its long edges.

  • Computer adapted apparatus and method for pricing lengths of material
    Patent number: 4394740
    Abstract: Apparatus and method for measuring unit or remnant lengths of material, calculating the price and developing related sales information adapts to use in a system wherein the measuring and related data entry operations are performed at a plurality of terminals connected to a central computer. Each terminal employs a measuring roller and associated optical-electronic measuring and data processing circuitry. The measuring roller moves bi-directionally to increment or decrement the measure and is adapted for being repositioned to a precise home position at the commencement of each measuring operation. Electronic "noise" encountered with prior art optical-electronic length measuring and price computation apparatus has been substantially eliminated and operation improved by use of visual and audio cues for the operator.

  • Apparatus for stacking lumber
    Patent number: 4384814
    Abstract: A push-on type lumber stacker utilizes a pivotal conveyor for receiving boards from a bulk supply and discharging complete courses of boards onto a lumber stack. The discharge end of the conveyor pivots upwardly in correspondence with the increasing height of the stack. The pivotal conveyor incorporates a plurality of automatically actuated stick holders which hold the stacking sticks as runners during formation of each course and then release the sticks to serve as course spacers in the stack. A plurality of chain-mounted discs on the conveyor assist in pushing the boards onto the stacking sticks and, in conjunction with other auxiliary apparatus, enable one course of boards to be built up on the conveyor while another course is held ready for discharge.
