This will facilitate changing the adapter plate 3 whereby to provide for larger or smaller light bulbs’ and bowls as desired. However the bowl may in some instances, de pending on the size of the light bulb, have to be removed from'the plate 3 before unscrewing the hub 4 and this can be readily accomplished by 10 removing the fastenings 22. It will be .noted that all joints of the ?xture are gasketed and arranged'to provide effective moisture and dustproofseals. It should also be noted that with this ?xture no fastening screws or the like are required to secure the bowl supporting plate in place. The V fastening means therefor is not visible when the ?xture is assembled whereby to improve the ap pearance of the ?xture as a whole and provide for an easier installation and removal thereof. I claim: ' r ' 1. In a light ?xture, an outlet box adapted to be placed on one side of a wall or ceiling, a threaded extension on said box, a clamping and 25 adapter plate adapted to engage the other side of. the wall or ceiling, a hub integral with said ‘plate and threadedly engaged with said extension, a light socket held in place by and between said extension and hub and extending into the latter, a bowl and means for securing said bowl to said plate and a clamping ring threaded on said hub and adapted to clamp against the wall or ceiling. '2. In a light ?xture, an outlet box, a threaded extension on said box, a ?ange in said extension, a clamping and adapter plate, means on said plate for securing a bowl in sealed engagement therewith, a hub formed integral with said plate and having threaded engagement with said ex tension, a light bulb socket in said hub, a holder 10 to which said’ socket is secured and which is clamped between the upper end of the hub and said ?ange and a clamping ring threaded on said hub and being opposed to said plate. 3. In a light ?xture, an outlet box, a threaded 15 extension on said box, a ?ange in said extension, a clamping and adapter plate, means on said plate for securing a bowl in sealed engagement therewith, a hub formed integral with said plate and having threaded engagement with said ex tension, a light bulb socket in said hub, a holder to which said socket is secured and which is clamped between the upper, end of the hub and said ?ange and a clamping ring threaded on said hub and being opposed to said plate, said plate 25 and bowl therein being detachablev as a unit upon unscrewing said hub from said extension.
