Abstract: A ladder safety device configured to be secured to the edge of roof to prevent a ladder leaned against it from sliding sideways or falling away from the roof edge. The ladder safety device comprises a generally flat, planar inner body portion comprising a first inner horizontal rail and vertical rails spaced from one another to define a plurality of large hand-grip openings between them. The ladder safety device further includes an outer body portion comprising a second horizontal rail spaced vertically from the first horizontal rail and connected thereto by outer portions of the vertical rails. Fastener holes formed along inner ends of the vertical rails can be used to secure the device to a roof, and projecting outer fingers define a ladder recess on an outer edge of the outer body portion. The ladder safety device is installed with the outer horizontal rail and portions of the vertical rails and the hand-grip openings spaced outwardly from the roof edge to provide a hand grip.

Abstract: A table saw having a stationary blade and a parallel moveable blade for straightening uneven dimensional lumber of the type used in cabinetry and other relatively fine woodworking. The table saw has a workpiece support frame with a lateral blade opening allowing the moveable blade to be shifted laterally and adjust the spacing between the blades. Powered feed rollers located above the table are used to clamp and feed a workpiece through the table while preventing kickback. A sacrificial fence including a blade guard recess is associated with the stationary blade, and includes a shutoff switch automatically activated to disable the stationary blade for solo use of the moveable blade.
