Abstract
21,197. Assersohn, D. Sept. 24. Incandescent lamps.-Tubular lamps are supported in trough-shaped reflectors by insulating cross-pieces which are each made in one piece, instead of having a detachable casing as described in Specification No. 17,855, A.D. 1907. The crosspiece shown in Fig. 1 has recesses A<1>, D for the lamps and electric connexions, and may be provided with an ornamental cover A<3>. The lower surface of the cross-piece is shaped to fit the reflector. Fig. 4 shows an alternative form. An intermediate support without electric contacts consists of a thinner block with a cylindrical hole.
