  • Patent number: 4670821
    Abstract: A light for MIG welders. The light is provided by a low voltage high intensity halogen lamp and parabolic reflector to focus the concentrated light beam on the work area at an intensity comparable to that of the welding arc to provide visibility through the user's shield. The light is provided with a clamp for ready attachment to the welding gun and has an adjustment for shifting the focus with a toggle and spring biased shock resistance. To resist thermal shock a pyrex lens may be employed or a tungsten screen which further resists spatter. Ventilation is provided by openings in the reflector and the tungsten screen.

  • Patent number: 4545440
    Abstract: A device for punching holes of varying size in sheet metal by a pneumatic hammer. A tapered punch is employed with an adjustment at the muzzle end of the hammer which selectively limits the travel and penetration of the punch thereby determining the size of the hole. A special attachment for the tapered punch and a punch holder for the punch is provided for attachment to the muzzle end of the pneumatic hammer. The attachment is in the form of a housing which receives the punch and punch holder and can be screwed on the muzzle end of a pneumatic hammer and present the punch holder to the internal hammer like drive of a conventional pneumatic hammer.
