NIGHT LAMP WITH RECEPTACLEI Filed Sept. 20, 1954 FIG-1 F i t I69 I k I IN VEN TOR.
ANTHONY A. McCARTHY ATTORNEYS United States Patent M This invention relates to an electrical fixture, particularly a night-light adapted to be mounted within a standard electrical receptacle box.
One of the greatest disadvantages of the ordinary type of night-light now in common use is that such a light,
when plugged into a wall receptacle, projects outwardly .from the surface of the receptacle, and therefore outwardly of the wall, a considerable distance. These lights are commonly held in place only by the two prongs received within the receptacle, and may be easily dislodged with resultant breakage of the light if it falls upon a hard surface, especially since these lights are ordinarily made of relatively brittle plastics which will not withstand the shock of such a fall.
Furthermore, the light may be easily removed and misplaced so that it is not to be found when most needed. 'For example, if a housewife ordinarily keeps such a light in a childs room and removes it to use the receptacle for other purposes, the light may be mislaid and therefore unavailable late at night when it may become necessary to have a small light in the room.
The present invention provides a combination nightlight and receptacle which overcomes these disadvantages by a construction which is designed to replace the ordinary double receptacle and still provide a single receptacle outlet, together with a night-light which is enclosed within the receptacle box and therefore substan- Despite the semipermanent nature of the installation of the present invention, it is easy to remove and to service, and may be received within any standard electrical receptacle box. It is therefore an object of this invention to provide .a combination night-light and electrical receptacle which may be mounted within any standard receptacle box.
Other objects and advantages of the invention will be apparent from the following description, the accompanying drawing and the appended claims.
In the drawing- Fig. 1 is an elevational view of the device provided ,by this invention as it would appear in a normal installa- .tion;
Fig. 2 is a perspective View of the combination nightlight and receptacle provided by this invention and shown removed from the receptacle box;
Fig. 3 is a side view, partly in section and partly in elevation, of the device seen in Fig. 1;
.Fig. 4 is an elevational view of the bottom half of the unit seen in Fig. 2;
* Referring to the drawing, which illustrates a'preferred embodiment of the invention, and specifically to Fig. 2,
there is seen a combination night-light and receptacle having a base 10 with an upstanding boss 12 divided into a lower portion 13 integral with the base and a complementary upper portion 14. The pair of parallel ribs 15 depend from the bottom of base 10 and extend parallel to each other entirely across the base, as seen in Fig. 5. The upper boss portion 14 is fastened to lower boss portion 13 by a bolt 17 threaded at its upper end to upper boss portion 14 and terminating substantially flush with the upper surface thereof. This bolt also has an internal bore 18 at its upper end which is threaded to receive a short screw 20 (Fig. 1) for attaching a cover plate 22 over base 10.
A strap 25 having a generally U-shaped center portion 26 and outwardly extending wing portions 27 each slotted at 28 embraces base 10 and boss 12, with the wing portions extending outwardly away from the base and substantially parallel thereto. The base is of such proportions as to be received within any standard electrical receptacle box, for example as seen in Fig. 3 at 30 as including a pair of outwardly disposed wings 31 extend ing at opposite sides of the open face of the receptacle box and receiving connecting screws 32 which pass through slots 28 in the strap and support the base within box 30. Such receptacle boxes are commonly mounted within a recess in a wall, with their open face substantially flush with the wall to receive electrical receptacles and retain them in substantially flush relationship to the wall.
Referring to Fig. 4, wherein the upper boss portion 14 is removed, there is seen a threaded socket 35 which is received between a recess 36 in lower boss portion 13 and a complementary recess 37 (Fig. 6) in upper boss portion 14. Also recessed into lower boss portion 13 is a switch 40, preferably of the single push button type having an upstanding operating shaft 42 which projects through a hole 43 in the upper boss portion when the parts are assembled as in Fig. 2. At the bottom of base 10, outwardly of ribs 15 and preferably below socket 35 and switch 40, are a pair of contacts including strips 45 and 46 which are molded into or otherwise secured at one end to base 10 and each having a screw 47 received therein for engaging the opposite wires of an electrical supply. The rib portions 48 depend from the sides of the base outwardly of strips 45 and 46 to provide protection against knocking the strips loose from the base and for the ends of the electrical wires attached to screws 47.
Switch and socket 35 are wired in series to strips and 46 by a connector bar 50, which is preferably molded into base 10 and attached at one end 'to one contact 51 of switch 40, and a second connector bar 52 likewise preferably molded into the base and connected at one end to strip 46 and at the other end to the button 53 of socket 35. The other contact 54 of the switch is connected by a short wire 55 lying within a recess 56 in lower boss portion 13 to the outer or screw connection of the socket.
Socket 35 opens on the wall 60 of boss 12 facing the other end of base 10, and a bulb 62 is received within the socket and thus held over the other end of the base beneath cover plate 22 because of the spacer action of boss 12. Lighting of the bulb is controlled by switch 40.
At one corner of boss 12, as seen in Fig. 2, is an electrical receptacle 65 having a face portion 66 raised somewhat above the surface of upper boss portion 14 and including a pair of spaced apertures 67 for receiving the prongs of an electrical plug. Within apertures 67 are contact strips 68 and 69 (Fig. 6) for engaging the ends of the plug prongs and connecting them to the electrical supply throughcontact strips 45 and 46 respectively. In assembly, strip 68 rests upon bar 50 and strip 69 rests upon a bar 70 which is in turn connected to bar 52, thus wiring receptacle 65 in parallel with socket 35 and switch 40. The completed unit is thus wired for a controlled supply of electricity from a source 72 (Fig 7) and to socket 35 and a continuous supply to receptacle 65.
Plate.22-is-provided with a first aperture 75 through whichthe. switch, controlshaft 42 projects in assembly, this being the only element on the unit which extends outwardly of the plate. A second aperture 76 receives the receptacle 65, with the upper face66 thereof in substantially fiush relation with the outer surface of theplate, and the plate also includes a light transmitting portion 78, in the illustrated embodiment shown asa number of longitudinal slits 79 through plate 22, in registry with base and bulb 62. It will be readily appreciated, however, that any manner of-light transmitting means such as transparent or translucent material could be utilized in place of these slits. As will be seen upon inspection of Fig. 1, the area of the light transmitting portion 78 is relatively large in relation to the area of the cover-plate 22, and provides for substantial illumination of the room immediately surrounding the plate 22.
It will thus be seen that the present invention provides an inexpensive and easily manufactured night-light and receptacle unit which maybe received within any standard receptacle box, and-which is wholly contained within the box with the exception of the switch control shaft 42 which normally projects outwardly of the cover plate no more than half an inch. In order to replace the bulb or remove the unit it is necessary only to remove screw and plate 22 for access to the unit. While the switch may be of any convenient type it has been found most practical. to use the single push button type of switch rather than a rotary shaft type since the former provides greater ease of operation and eliminates the necessity of actually grasping the control shaft to operate the switch.
While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form-of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
