Referring again to the drawing, my improved
re?ector holder is generally indicated at H], and
comprises a hollow, open-ended body, as, for in

electric lamp l2 in the usual manner. The socket

type and is secured to the top wall M of the

an especially shaped tool, so as to make removal

When it is desired to remove the re?ector from
the holder, the screw 29 is loosened, and the re

arrow shown in Fig. 2, thus camming the movable
