Abstract

516,121. Tubular supports for electric lamps &c. COOPER, H. C. June 17, 1938, No. 18015. [Class 65 (ii)] A tubular support 10 for electric lamps &c. is rotatable in a socket 11 and is retained therein by a pin 15 in the socket engaging a groove 13 in the tube. A stop 14 in the groove limits the rotation of the tube by engaging the pin. Two or more grooves may be provided for adjustment purposes, or a single wide groove may co-operate with two staggered stops and a single pin. Several holes may be arranged in the socket, to vary the amount of rotation of the tube.
