  • Patent number: 4428457
    Abstract: A window bracket is constructed to be supported on a window sill and the walls beneath the sill of an open window and further constructed to hold a safety scaffold to permit work on the exterior of the building, either on the windows or the area between windows. It may be used in pairs to hold a scaffold or in greater numbers where the scaffold is longer and extends over a greater area of the building exterior. It is rigidly constructed by welding of steel or aluminum alloy for rapid installation through open windows and is equipped with safety railings and reinforcing brackets to insure complete safety of workmen working on the outside of the building, such as repairing the exterior wall, painting or washing or repairing the windows from the exterior of the building.

  • Patent number: 4190920
    Abstract: A device for clearing plugged garbage chutes is specially constructed to make it adaptable for use in multi-story buildings, such as apartment houses, having vertical chutes extending through several stories down to a receptacle in the basement of the building. The clogging of these chutes is generally caused by an accumulation of old newspapers, shopping bags and other large pieces of paper. A device of generally Tee-shaped configuration comprises a series of sharp pointed cutting edges positioned on the cross of the Tee and grabbing arms at either end. An extensible handle comprises the vertical portion of the Tee which in turn is comprised of relatively short sections which may be coupled together to facilitate insertion into the chute to varying elevations. A removable handle is positioned at the lower end of the Tee to permit rotation of the device to effect cutting through the obstruction and pulling out the obstructing material.
