  • Patent number: 5154383
    Abstract: The holder has an elongated base portion adapted to extend from above one rung of a ladder to below an immediately lower rung, and an elongated cantilevered portion extending integrally from the upper end of the base portion at an angle of preferably less than 90 degrees therefrom. The distal end of the cantilevered portion has an upward hook-like projection to support the bail or handle of a paint can or the like. Preferably, a substantial portion of the cantilevered portion has a cross-section in the form of an upwardly-opening U-shape defining a trough to hold a paint brush, with a drain hole being provided through the bottom of the trough near the distal end. The cantilevered portion preferably has a dam piece near its distal end between the distal end and the location of the drain hole, so that paint cannot run past the dam piece, and can only drain out the drain hole.

  • Patent number: 5154255
    Abstract: A ladder shoe for providing enhanced stability between a ladder and a variety of surfaces. The ladder shoe is comprised of a shoe body having a first side plate, a second side plate and a base. The first side plate and the second side plate are attached to the base. The side plates include curved slots through which a fastener is disposed which movably connects the ladder shoe to the end of the ladder's side rail, thereby allowing the ladder shoe to move between a first position where the base is at a first angle with respect to the side rail and a second position where the base is at a second angle with respect to the side rail. Each slot has a notch in which the fastener catches causing the shoe to be maintained in an intermediate position until the shoe body is desired to be placed into another position. The base has a bottom which provides a slip resistant surface for engaging the shoe body to essentially flat surfaces when the shoe body is in the first position.

  • Patent number: 5143173
    Abstract: A plank for use on a scaffold. The principal component is a hollow integral aluminum extrusion with an elongate rectangular shape transverse to its length. The extrusion has a top wall, a pair of spaced-apart opposing sidewalls extending downwardly from the top wall, and a longitudinal locking structure located between the sidewalls. A complementary fastening assembly cooperates with the locking structure to secure the extrusion to a horizontal cross-member of the scaffold. Sheet material containing mineral particulates is adhered to the upper surface of the extrusion to provide a non-slip walking surface. After use in an environment containing dangerous contaminants, such as radioactive materials, the sheet material may be stripped for disposal and the extrusion cleaned with an appropriate solvent before re-application of fresh sheet material.
