  • Patent number: 5148694
    Abstract: An apparatus for forming sheet metal panels is provided. One embodiment generally includes a frame structure, a pair of laterally displaced longitudinal supports slidably interconnected with the frame structure, a forming assembly positioned along both of these supports, a plurality of screw rods extending between and threadably engaged with the supports, an advancing assembly positioned substantially about the central longitudinal axis of the frame, and a cutting assembly. The spacing between the supports is adjusted to accommodate for various widths of the sheet metal by rotating the screw rods which either draws the supports in or forces them out substantially the same distance. Sheet metal is then provided to the advancing assembly which engages and moves the sheet metal through the forming assembly. After the desired contour of the sheet metal is achieved by passing through the laterally displaced portions of the forming assembly, the cutting assembly cuts the sheet metal panel to the desired length.

  • Patent number: 4161769
    Abstract: Combined hand rail and lighting fixture for a walkway, such as a stair flight, characterized by a tubular member with spaced openings in a lower portion of its wall in which are disposed lighting fixtures, each comprising an extruded housing, a reflector for supporting an illuminating bulb, and an extruded arcuate window closing an opening, the housing and reflector forming a space for receiving the requisite electrical conductors. Its construction is such that it inherently prevents entry of water and hence may be employed outdoors as well as indoors. After installation and wiring, the housing is preferably secured to the hand rail and replacement of a bulb may be effected by removal of a pair of securing clips and the window, only, without disturbing the housing or permanent wiring connections.
