  • Patent number: 5787751
    Abstract: Plural station apparatus and method is provided for the making of articles of manufacture from sheet material. The first work station performs a first cutting operational step on the sheet material to cut a plurality of precisely cut blanks, and two bending or folding stations perform the finishing step on the blanks to produce the articles of manufacture. The first station is located above the bending or folding stations, and it is laterally offset from each of them. The first station is laterally offset in a first direction with respect to the first work station, and the second is laterally offset in a second direction with respect to the first work station. Two inclined chutes are provided between the output of the first station for allowing the precise blanks to slide by gravity to the input of the first and second bending or folding stations. Thus, the inclined chutes automatically transfer the precise blanks from the first station to the two bending or folding stations solely by gravity.

  • Patent number: 5771736
    Abstract: Plural station equipment is provided for the making of articles of manufacture from sheet material such as sheet metal. The first work station performs a first operational step on the sheet material to form precise blanks, and the second station performs the finishing step on the blanks to produce the article of manufacture. The first station is located above the second station, and it is laterally offset from the second station. An inclined chute is provided between the output of the first station for allowing the precise blanks to slide by gravity to the input of the second station. Thus, the inclined chute automatically transfers the precise blanks from the first station to the second station without any manual intervention or the need of complex electromechanical transfer equipment. In a specific embodiment, the sheet material is sheet metal, and articles of manufacture are roof flashings.

  • Patent number: 5608993
    Abstract: A sheet metal mini-wall parapet structure is provided. The structure is basically a U-shaped member formed of sheet metal. At one lower corner of the U-shaped member is formed the cleat used to attach the conventional coping member. The cleat is formed by extending one leg of the U-shaped member downwardly and folding it over in a continuous fashion with an extension from the bottom of the U-shaped member. The upright legs of the U-shaped member are staggered in height so that when a top member is attached, the top member is sloped in one direction so that any water accumulating on the top of the mini-wall parapet is drained toward the roof. The top member is usually of 3/4" pressure treated plywood which is screwed into bent over flanges along the tops of each leg of the U-shaped member. Before the top member is screwed into place, the void within the sheet metal legs can be filled with insulation to minimize heat loss through the mini-wall parapet.
