  • Patent number: 4529238
    Abstract: A carpet handling tool for facilitating the gripping and pulling of carpeting by its edges. The tool comprises two arcuately curved handle members which are pivotally coupled together to form a fulcrum. Individually attached to each handle member is a gripper jaw in the form of a generally flat plate having its leading edge bent at a right angle and arranged such that the leading edge of one jaw member overlaps that of the other to define a predetermined space therebetween. When a segment of carpet is placed between the jaw members and the arcuate handles are squeezed together, the carpet is tightly gripped by the jaws and a substantial, two-handed pulling force may be applied to the handle members to manipulate the carpet.

  • Patent number: 4400911
    Abstract: A security grill which may be placed within a window frame to prevent break ins. In one arrangement, the grill comprises a first channel member adapted to be affixed to the window sill and a second channel member adapted to be secured to the upper window frame. Fixedly attached to the second channel member at predetermined spaced apart locations therealong are tubular stubs of a predetermined length. The bottom channel member has a pattern of apertures extending through the top wall thereof with a spacing between apertures corresponding to the longitudinal spacing between the stubs on the upper channel member. Fitted into the apertures in the second channel member are a plurality of bars which extend outwardly therefrom so as to be insertable within the stubs on the first or upper channel member.

  • Patent number: 4332371
    Abstract: An apparatus and method for removing worn carpeting which may have been adhesively bonded to the floor of a building. The method involves the steps of affixing a power winch mechanism to the floor of the building proximate one side edge of the carpet to be removed and affixing pulleys, in pairs, on opposite side edges of the room. A rope from the winch is routed through said pulleys and the free end thereof is connected to an elongated clamp mechanism secured to one edge of the carpet to be removed. By energizing the power winch, the old carpeting is peeled back to the middle of the room, at which time, the rope is routed through a different pulley to a further carpet clamp whereby the pulling force acts in an opposite direction to complete the peeling of the remaining half of the carpeting to the middle of the room.

  • Patent number: 4295777
    Abstract: An assembly for facilitating the lifting and repositioning of heavy rolls of sheet material, such as carpet rolls and the like. First and second jack assemblies are mounted separately on two frames, each supported by two casters. The jacks have stubs of predetermined lengths which can be raised and lowered as the jack handle is manipulated. Extending between the stubs on each of the jack assemblies are a plurality of joined segments of pipe which pass through the center of the roll to be lifted. As the jacks are operated, the load is elevated from the floor to a desired height and, because the jack assemblies are on wheels, the load may be moved laterally as well. The frames on which the jack assemblies are mounted also include a plurality of upwardly extending stubs for facilitating self-storage of the plural pipe segments when they are not in use.

  • Patent number: 4241930
    Abstract: A two-wheel hand truck which includes a generally rectangular frame having parallel and spaced apart side members and cross members with a hinged or foldable toe plate which allows it to project forwardly from the plane of the frame or, alternatively, can be folded flush to the frame. The wheels are mounted outboard from the sides of the frame and project rearwardly therefrom to thereby provide increased stability. Handles are adapted to be connected to the upper portion of the frame and they too project rearwardly. The diameter of the wheels and the length of the handles are dimensioned such that when the cart is laid down with the ends of the handles abutting the ground, the plane of the cart is generally horizontal. First and second elongated rollers are journaled for rotation between the aforementioned cross members to thereby facilitate the dispensing of carpeting and the like from a roll.
