UNITED STATES PATENT OFFICE.
WILBERT E. MCDONALD, OF CHICAGO, ILLINOIS.
ELECTRIC-LAM P RECEPTACLE.
SPECIFICATION forming part of Letters Patent No. 671,603, dated April 9, 1901.
Application filed September 221 1897- gelifbl NO- 6 3- (N0 model-3 T0 aZZ whom, it may concern:
Beit known that LWILBERT E. MCDONALD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric-Lamp Receptacles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to improvements in electric-lamp receptacles; and it embraces an improved construction in such receptacles whereby the receptacle is fastened directly to and forms a part of the conduit containing the wires that form a part of the electric circuit in which a lamp is to be placed.
The invention consists in the matters hereinafter described, and pointed out in the appended claims.
It has been common heretofore to employ in connection with electric circuits electriclamp sockets into which lamps could be inserted. These sockets or receptacles, however, have been of such a construction that their outer shape corresponded closely to the size and shape of the aperture into which the end of the lamp was to be placed. These sockets also are usually attached to or depended from the conduit in such a way that the conduit could be hidden inside a wall or beneath the plaster on the wall, and the socket would project a short distance beyond the wall, so that the end of the lamp could be inserted into it. In some cases, however, it is preferable to have the conduit exposed, and in these cases if the socket is attached to or depends from the conduit it presents a very crude and unsightly appearance.
My invention consists, essentially, in means whereby a lamp socket or receptacle is fastened into and forms a part of the conduit to which it is attached, thereby making a much neater arrangement.
In the accompanying drawings, illustrating my invention, Figure 1 is a View showing one form of a socket or receptacle fastened into and forming a part of the conduit. Fig. 2 is a View showing another section of Fig. 1. Fig. 3 isa view showing a slightly different form of receptacle also forming a part of the conduit.
In said drawings similar reference-signs are used throughout to indicate similar parts wherever they occur.
In Fig. l reference-signs 1 and 2 represent a lamp-receptacle in the form of a ball in which the parts 1 and 2 form the two halves. These two parts are so constructed that they fit together and form one harmonious Whole. The conduits 4: and 5 are fastened to the upper half 2 of the receptacle in any suitable way. As shown in the drawings, the con duits et and 5 are threaded on their ends and are screwed into two apertures in the part 2 of the receptacle. I do not desire, however,
to restrict myself to any special method of attaching the conduit to the receptacle, as many ways of doing this will be apparent to any one skilled in the art and which could be used without departing from the spirit of my invention. The lower half 1 of the receptacle is fastened to the upper half 2 by means of two small screws 12 12. In the lower half Iis the aperture 6, through which the end of a lamp can be inserted, and fastened into the interior of the upper half 2 is a socket 3 of any suitable construction to suit the end of the lamp that is to be used. In the drawings I have shown a socket adapted to hold and retain a lamp by means of a threaded screw. It is evident, however, that any of the well-known means might be employed for retaining the lamp in the socket Without departing from the spirit of my invention. The electric wires 8, 9, 10, and 11, that form a part of the circuit in which the lamp is to be placed, are shown in the interior of the conduit. These wires are fastenedone to each side of the socket 3 by means of the screws '7 7. The electric current will then pass along one of the wires 8 or 9 through one of the screws 7, then through the lamp, then to the other screw 7, and back through the other wire 8 or 9; but as no claim is made on any special form of construction of the socket itself and as there are many well-known forms of sockets now in the market I do not deem it necessary to explain in greater detail the interior construction of the socket. The
wires 10 and 1.1 are a continuation of the wires 8 and 9 and are for the purpose of conveying the electric current to other points. If it is not desired to convey the electric ourrent to other points, the form of receptacle shown in b can be used, in which only one conduit instead of two is attached to the receptacle. It is, however, evident that one or more conduits might be attached to the receptacle and that they might be attached in many dili'erent ways without departing from the spirit of my invention so long as the receptacle formed an essential part of the conduit. It is also evident that this receptacle can be of many different shapes and designs and that the aperture 6 could be in many different positions in the receptacle without departing from the spirit of my invention.
Having explained the object and nature of my invention and various forms of construction embodying the principles thereof, what I claim as new and of my own invention, and desire to secure by Letters Patent of the United States, is
1. The combination ofa conduit, aspherical holder consisting of two equal sections and containing a lamp-socket, means for fastening the two halves of the holder together and a projection from one half of the holder containing a threaded aperture for Fastening the conduit to the holder in alinement with the division between the two sections substantially as described.
2. The combination ofa conduit, a spherical receptacle forming an essential part thereof and consisting of two equal sections, a lampsocket contained therein and fastened in one section, an aperture in the other section through which a lamp can be inserted into the socket and a projection from the section in which the socket is fastened which contains a threaded aperture for fastening the conduit to the receptacle in alinement with the division between the sections substantially as described.
The combination ofa conduit, a spherical receptacle forming an essential part thereof and consisting of two equal sections, a lampsocket contained therein and fastened in one section and means for attaching the conduit to the same section whereby it will be in alinement with the division between the sections substantially as described.
4. The combination ofa conduit, a spherical receptacle forming an essential part thereof and containing a lamp-socket, wires in said conduit and receptacle, a projection from one half of the receptacle for fastening the conduit to it in alinement with its center and an aperture in the other half of the receptacle through which a lamp can be inserted into the socket substantially as described.
In witness whereof I have hereunto set my hand in the preseuceof two subscribing witnesses.
