Abstract

By providing, for use in a repair-truck installation, a lighting bar including the combination of a lamp having a rectangular, spreading beam with a lamp having a round flooding beam, the combination being supported rotatably from a pole which is attachable to a truck on which the combination is being carried, displacing the lamp with the rectangular, spreading beam from the axis of the vertical supporting pole by a distance sufficient to permit the rectangular beam to illuminate a significantly large work area local to the truck while the lamp with the round beam is supported at a lesser distance from such axis to permit illumination of a work area remote from the truck, repair work, for example on a remote gas meter may be conducted simultaneously with related preparatory work at the truck without light switching or transporting, thus increasing the efficiency of the repair personnel and the accuracy of their work.

Claims

1. A lighting bar including:

an arm intended in use to be horizontal;

first and second electric lamps supported from said arm proximate the opposite extremities thereof;

said first electric lamp having, in operation, a beam of rectangular cross-section;

said second electric lamp having, in operation, a beam of circular cross-section;

a pole intended, in use, to be vertical;

coupling means, said coupling means including a plate secured, in a horizontal position, to the upper end of said pole and having an opening therein, centrally thereof;

a vertically disposed threaded shaft fixedly connected to said plate, passing thru said opening in said plate and extending above said pole, said arm having a vertical opening therethru to receive said shaft freely, for rotation of said arm about said shaft, said vertical opening in said arm being positioned off the longitudinal center of said arm whereby there is a greater distance from said first lamp to said vertical opening than there is from said second lamp to said vertical opening;

a nut having internal threads sized and pitched to cooperate with said threaded shaft and positioned on said shaft on the opposite side of said arm from said plate, whereby said nut can be adjusted to cause said arm to forcefully engage said plate;

said nut having a horizontally-disposed setting-pin therein;

said first electric lamp being supported for rotation only in the horizontal plane but through 360° and

said second electric lamp being supported for rotation through only 180°

in the horizontal plane but is also rotatable in the vertical plane.

and means for providing electrical energy to said first and second electric lamps.

2. Apparatus according to claim 1 which includes, in addition, mounting means permanently connected to said pole for mounting said pole on a truck.
