  • Patent number: 6196429
    Abstract: A dress or clothing form includes a sheet metal back to which are attached a plurality of reinforcing strips. A support rod is carried on one of the reinforcing strips and on the back. Leg supports are attached to the back to which are attached a pair of flat leg panels. Front and back molded plastic body panels are secured by fasteners to the metal back and similar molded front and back leg panels are secured to the flat leg panels. The support rod includes a large diameter portion at its top which includes a tapered surface. This surface mates with a socket on a support arm attached to a stand for supporting the form at the desired height. The stand includes telescoping members each including a rack with one member including a gas spring connected to a pinion positioned between the racks. The gas spring is arranged to essentially balance the weight of the dress form and garment so that a worker can move it up and down with little effort.

  • Patent number: 4747212
    Abstract: A cutting device for plastic pipe for use principally in the aid of plumbing, swimming pool and spa installations. The pipe cutter is designed specifically to be used or attached to a hand held drill motor of the type which tradesmen commonly carry and use for drilling holes and setting screws. The pipe cutter includes a body which is attachable to the front of a drill motor and houses a dual directional linear actuator such as an epicyclic ball screw with bi-directional brake. The epicyclic ball screw linear actuator responds to the chuck or rotating shaft of the drill motor. The housing defines or holds a U shaped recess or cradle for receiving a plastic pipe extending transverse to the length of the housing or more particularly on center or to the axis of the drill motor shaft. A guillotine type of cutter blade is driven by the screw actuator to move through a slot into the cradle to be driven through the side wall of the pipe and therefore sever the pipe within the cradle.
