29,155. Joseph, E. L. Dec. 9. Incandescent lamps, holders for. A flanged cylindrical insulator a is made in two halves, as shown in section in Fig. 5, and with recesses g to receive two plunger holders h, which have been previously secured to the supply conductors by screws i. These parts, having been put together, are placed in a metal socket b, Fig. 2, and secured by a top-piece e and screw coupling-sleeve f. A projection on the socket b enters a recess l in the insulator to prevent turning. One half of the insulator may have a projection fitting into a recess in the other, between the plunger holders.
