  • Patent number: 10526801
    Abstract: A board straightening tool comprising a handle non-rotatably attached to a cam rotatably attached to a locking dog provides force to straighten boards by grasping the joist supporting the tool and simultaneously wedging a shoulder of the cam against the board being fastened to the joist, and maintains a space between tool and board for edge-mount fasteners. Increased force against the board is provided by a fulcrum action of the cam to locking dog rotatable attachment and is maintained by locking the cam in place using a specially designed curved cam perimeter section that enables an installer to straighten a deck board while keeping his hands free. Locking dog locking fingers are constructed from a knurled metal for grasp power or of a smooth surface to reduce marring the joist. The tool also provides the force required to maintain consistently spaced gaps between the boards for a more desirable appearance.

The wedge comprises a top curved edge and a bottom edge including a groove therein. The pins typically are spaced from one another a distance slightly larger than the width of a joist. In use, the cross bar is placed on top of two adjoining joists so that the pins are positioned on either side of a single joist. The other end of the bar merely rests on top of the adjacent joist. A force is then applied to a side edge of the wedge in a direction parallel to the length of the sub floor boards. Due to the rounded shape of the top curved edge and the flat surface of the wedge that contacts the floor board, the wedge will rotate within the cross bar so that the edge of the wedge is flush against the sub floor board and so that the curved surface of the wedge will contact the cross bar at only one point.

    Abstract: The invention disclosed and claimed here is a lumber-straightening device for manipulating a cross-wise structural member relative to an underlying support joist. It includes a base plate which is releasably mountable to the support beam by a pair of pegs which rest on opposite side surfaces of the support beam. A hand-operated cylindrical cam head is pivotably mounted to the base plate. The point of pivotable attachment is off-center relative to the center point of the cam head. This allows the cam head to push a sliding plate against the cross-wise member for bending it into a desired position relative to the support beam. The direction of travel of the sliding plate follows a line or axis defined by the pivot point of the cam head and a separate guide pine, spaced from such pivot point, that follows a groove in the sliding plate. This relationship converts rotational force to linear force.

  • Patent number: 4592536
    Abstract: Apparatus for moving a load, particularly a stack of panels, along a roof structure, including a plurality of spaced-apart roof rafters and transverse purlins comprising: a roof-mounted rail for mounting on said roof in vertical alignment with a purlin, a load-carrying cart comprising a carriage having rollers movable along the rail, and a load-carrying platform mounted on the carriage for longitudinal and vertical movement relative thereto including an inverted U-shaped elongate channel member. Mechanism is provided for relatively longitudinally moving the load-carrying platform and the carriage between rest positions and longitudinally displaced positions. The carriage and load-carrying platform include cooperating camming rollers and cam receiving slots which upwardly guide the platform relative to the carriage as the carriage and platform are relatively longitudinally moved, to lift the load relative to the roof structure for subsequent rolling movement via the carriage on the track.

  • Patent number: 4280683
    Abstract: This invention is a utility construction tool for providing controlled amounts of force to a work-object by means of lever action. Specifically, the invention is a lever arm handle with a hooking device attached. A force applied to the lever arm handle will in turn apply a concomitant force to the end of the hooking device.
