To (ZZZ ctr/tom it may concern 'c it known that I, JEAN GALLAY, manulut urer citizen of Switzerlmid, residing at it ltoute (le Frontenex, Geneva, gwitzerhtnd, u have invented certain new and useful linproveincnts in Electric Search-Lamps for Automobiles; and I do hereby declare the following to be a. full, clear, and exact de scription of the invention, such as will enohle others skilled in the art. to which it ap- ')Qltfll15l.() inalze and use the same, reference wing haul to the zicconipunying rlrmving, and P g'ures of reference marked thereon, which 1 it part of this specification. 11E? "lihe present invention relates to electric search lumps for automobiles in which the ive surface of the reflector is hermetically i eluted from the surrounding space, whereby the deposite of dust and steam mist upon to such surface is entirely avoided. Moreover, the lamp may he adjusted in the focal plane of the reflect-or Without having to open the lantern for the purpose, which affords the further advantage of no exterior projection hein presented which might hamper cleani, o ierstionsh I The accompanying drawing illustrates a sniiehle inuniier of carrying out the objecthe inventici Figure 1, being it longitudion and Fig. 2 a section on line zv-y i ector oi oi the lamp is of parabolic at its forward part it terminates in. t forming 9, seat to receive the glass i) tilt}: rear a ring a". .ln a groove rnierl in. the rim (3 is situated a rubber 0 against which the glass 6 is pressed at front ring d1 screwing on to the rim a; This ring; is in section of mushroom form on its hl'idy constitutes a screw serving with its 5 erior edge to bind the glass. 5 against the indie ruhher pecking while its outer enihr'aces'the casing e of the lamp when the renector is in position.

The opening in the reflector for the passage of the lamp is h s movable hack 9 which can slide on the ring'f, at the front oi ilug f, and which is sold against the-reflector a by the l icafl springiz, hearing against the bottom of the plug 7'. i seated in u ring- 57 inomble ring 9 FtIlu threzulecl tube in. w? plug f. this tube sziges for the electric .lQllilS and. c2 ies u not To with stops, the not hearing ciiteriorly against 'iheplug while a. spring; 0 force the ring snot its tube 2% tows interior.
