This invention relates to ,t liohting fixture and iiaore particularly to a wall type of lighting fixture formed entirely of moldable insulating material, sucli as porcelain or tlie 5 like. It is a gelieral object of this invention to provide, a novel and iriproved foriii of li.ghtiiag fixture. More partictilarly it is. an object of the 10 preseiit invention to provide a, lighting fixttire of tl-ie wall typ(3 foriiied entirely of insulatiiig iiiaterial provided with ,t riiig or sleeve for retaining ,t socket, to--etlier Nvith i-iieans for securing said socket in said ring. 15 Anothei@ object of the pi-esciit invention consists in the provisioi of a lio,htino- fixture pi-ovided witl-i a pull chain socket the b6ttoiii of which is exposed and 'Lorms t chain guide. Still tnother object of the present inven20 tion consists in t novel arrangement of sepai-,-Lble socket and lightiilg fixti-ire -whereby a sliade holder ring or the like engages the sere shell of the socket to retain it in posiW tic,,, in the fixture. 25 A still f urtlier object of the present invention consists in the provision of novel interlocking iiieans between t socket and a fixtlire which is adapted to enclose the same to allow for ready ,tecess of the socket for-wiring and '00 yet to ietain it securely in positioii in the fixture. Otlier ,tiid f urtlier objects will be more apparent as the description proceeds. For a full unclerstanding of the present in35 -,,entioii reference should be had to tl-ie accomp,,tnying dranvings @tnd following specification wherein as disclosed by way of exai-nple oiily a, single eiiibodiiiient of the sa,me, with the -Linderstanding, however, that variolis 40 cliai-iges iiia@ be inade therein by those skilled iT-i t-lie ,trt NvithoLit dep,,Lrting frol-ii the spirit of tlid iniention or tlae se6pe of the attached claiiiis. In said drawings: 45 Fiutire I is a longitlidinal vertical section tliru t fixttire coiastriieted accordino; to the pi-esent invention, the socket being shown in ele,v,ition; Figi-ire 2 is a partitl triiisverse section on 50 line 2-2 of Figure 1 i Figu re 3 is aii elevation of the separable socl3:et structure shown removed froin the fixture; and Figu re 4 is a vertical section thru a shade holder ring which n-iay be used witl-i tl-ie fi)c- 5 ture. The invent-Lon conteliaplates the provision of a wall bracket or fixture for use in b,,tthrooms, kitchens and siiuilar places inel.ined to be moist and for this reason it is prei"oral)ly 60 forn-ied of poreelaii,.i altlio the inveiition is not Iii-nited to tl-iis -Lise or to the formation of the fixture of porcelain. It n-iay @e formecl of any iiioldable il"s'-'Iating material such as bal@@e lite or the lil@,o and nlay be iii,,Lde iii ,Lny 65 color to harn-ionize ivitli ti-ie sui,rouiiclin(ys.
