Abstract: The present invention provides a plastic support, for an electric lamp and for the enclosure for that lamp, which is resistant to flame, heat, cold, water, ice, sunshine and other natural environmental conditions; and that support makes it possible to eliminate the traditional metal mounting pan, length of metal pipe, and securing fittings. As a result, the support of the present invention can directly engage a wall rather than engage a metal mounting pan which must engage that wall, and the flexible conductors from the socket can be given a random orientation from that socket to the power-supplying conductors in the wall instead of having to assume the fixed orientation imposed by the use of a length of metal pipe. This means that the conductors can be shorter than normal; because of the elimination of the depth of the metal mounting pan, and also because the wires assume orientations comparable to hypotenuses rather than orientations resembling the altitudes and bases of triangles.

The elements are formed of tubular stock with the center element having reduced outer diameter at each end thereof and having a circumferential groove formed about each such reduced outer diameter. The reduced outer diameter end portions of the center element, in turn, seat respectively in enlarged inner diameter end portions of the end elements. A lug is formed from the material of each such end element by displacing the wall thereof in a swaging process.

Abstract: A cornice designed especially for illuminating a wall of a retail store or the like, of knockdown construction for quick and easy erection and demounting. This invention is an improvement over that disclosed and claimed in my U.S. Pat. No. 4,251,855 issued Feb. 17, 1981. Like my patented invention, units in the instant case are tailored to fit a specific installation with a minimum of on site labor and little or no material waste. A major improvement in this case comprises means facilitating multiplying the vertical dimension of a cornice embodying my invention. This is accomplished by nesting together, in upper/lower relation, a pair of similar cornice units, as by interengaging marginal flanges at the upper and lower edges of the respective units. Accidental displacement may be insured against by such means as resilient tangs or prongs on one unit bearing yieldingly against an adjacent face of the mating unit.

Abstract: A lamp carriage arm, adapted for attachment to a safety hat, is disclosed. The lamp carriage arm offers improved lighting for miners and other workers by virtue of the lamp being positioned roughly in the area of above and in front of the safety hat wearer's collarbone. The lamp carriage arm attaches at one end to one side of the safety hat, and extends downwardly in spaced relationship to the side of the safety hat wearer's head. Conventional lighting, e.g. a miner's lamp, is carried at the other end of the lamp carriage arm. Preferably, the attachment of the lamp to the carriage arm is pivotal, so that the direction of the lamp beam may be varied. Thus the use of a ball and socket joint is disclosed, although other means may be employed. Adjustment means for varying the position of the lamp are also disclosed.

A threaded opening in the truncated section of the top receives the threaded end of a tubular swing arm of the swing arm assembly along a line which is at an angle of 45.degree.
