Oct. 11, 1932. w. NOBLE WALL PLUG AND RECEPTACLE Filed June 27. 1929 Patented Oct. 11, 1932 WARREN NOBLE, OF DETROIT, MICHIGAN ASSIGNOR TO ELECTROMABTER, INC OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN V WALL PLUG AND RECEPTACLE' Application filed June 27,

This invention relates to electric wall boxes and has for its object to providea wall box including a plug and a receptacle together with a suitable retainer therefor which may be attached to a wall in order to eliminate the form of switch boxes which are used at present and which are rather large and unsightly and comparativel expensive to install. This plug being 0 the type to carry a heavy current load, as, for instance, to an electric range will be understood to be of a very sturdy nature.

Another object of this invention is to provide a housing for the aforementioned wall box which will retain all the component parts of the receptacle in assembled position and acts as a complete housing for the said receptacle together with a substantial amount of the plug in order that the junction line between them may be well shrouded for general protective purposes.

A further object of the invention is to provide a device as described which will extend substantially longitudinally of the' wall to 2 which it is attached in contradistinction to protruding outwardly at right angles to the wall, and to integral feature of the maintain the plug receiving end of the receptacle in spaced relation with the wall to a suflicient extent to forestall any damage to the wall or to the plugby a scraping action upon insertion of the plug. In" carrying this into effect, I prefer to construct the receptacle housing in two parts, one of the parts enclosing three sides of the receptacle body while the remaining side is open, lateral walls being provided with tapered recesses to give a wedge shaped entrance for the base plate,

the whole receptacle assembly being secured to the wall by screws extending therethrough.

Other objects and advantages suchas ease and cheapness of manufacture, neatness and the like, will become hereinafter apparent as reference is had to the accompanying drawing wherein is illustrated, by way of example, a practical embodiment of my invention, and in which: I

The receptacle body comprises two prefera ly identical members 7, such as of porcelain, suitably recessed in their meeting faces at 8 to receive contact members9 and the ends of electric leads 10 together with the means, such as 11, securing the said leads to {)he iillner ends of said contacts. These memers members agalnst displacement within the housing. It will be seen that the screws which secure the housing to the wall, and the wedge plate 4 whlch is in turn secured into positlon by the said screws, together form a very simple and effective method of assembling and firmly locking the receptacle body within the housmg.
