Abstract: A fall-arrest anchor comprising a single, elongated member having a breaking strength more than 5,000 lb (22.5 kN). The single, elongated member comprises a first anchor portion sized and configured for attachment to a building and a second worker-attachment portion sized and configured for attachment to a worker's lifeline. The first anchor portion is at least about twice as long as the second worker-attachment portion, and the first anchor portion and the second worker-attachment portion are joined at an angle such that subjecting the fall-arrest anchor to a fall-arrest stress load visibly deforms the fall-arrest anchor and visibly changes the angle.

Abstract: Full body safety harnesses for fall arrest comprising a substantially rigid, resilient and water-resistant core throughout substantially the entire body harness frame.

Abstract: A self contained apparatus is utilized for direct movement on and across a roof surface to lay on the roof surface a continuous sheet or roofing material being removed from a roll guided at each of its ends by this apparatus, and being heated, before being removed, by a heating assembly pivotally supported by the apparatus and pivotally adjusted, so the distance between the roll and the heating assembly is maintained. An inclined A frame of the apparatus has a handle at its apex, and bottom opening slots at its lower ends to fit over the ends of a shaft on which the roll of roofing material is positioned. There is a depending wheel assembly below the handle serving to complete the triangular support of this self contained apparatus. The inclined A frame is pivoted about the wheel assembly to clear the bottom opening slots from the shaft ends and vice versa, when a roll of roofing material is being supplied, withdrawn, and/or adjusted to a different set of slots.
