  • Transverse arc tube mounting
    Patent number: 4422004
    Abstract: Transverse mounting of an arc tube with a pivoting attachment to a support rod extending through a lamp jacket is effected by a hinge plate comprising a metal ribbon folded back on itself and encircling a hinge pin. The hinge plate is welded to the support rod, and the hinge pin together with a wrap-around metal band clamps the pinched upper end of the arc tube. A two-piece connector having a bendable joint serves in lieu of a latch and assures accurate orientation of the arc tube after it has been transversely erected within the jacket.
