LIGHTING FIXTURE Specification of Letters Patent.

Patented Feb. 7, 1922.

Application fled llebruarr '5', 1921. Serial No. 8,188.

To all whom it may concern:

Be it known that I, Cmnnns F. ECKHART, a citizen of the United States, and resident of Milwaukee in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Lighting Fixtures, of which the following is a description, reference being bad to t e accom anying drawings, which are a part 0 this specification.

This invention relates to certain new and useful improvements in lighting fixtures and refers more particularly to that type of fix ture, the base or body of which is preferably formed of molded plastic material.

It is the present custom in manufacturing lamps in which the body is formed of molded material to provide an expensive form of lamp socket, which materially increases the cost of production thereof.

Hence with the above and other objections in mind my invention has for one of its objects to provide an improved method for molding the lamp stand in which the lamp receiving socket is constructed in the cheapest manner possible, and secured in place at the time of molding the base.

Another object of this invention is to provide a lamp fixture of the cla$ described in which the light receiving socket is molded at the time of forming the fixture, and is surrounded by a boss or projection to which a shade support may be readily attached.

A further object of this invention resides in the novel method of moldin the fixture whereby the electric cord attac ing plug is utilized to retain the socket forming means in osition while the fixture is being molded.

X still further object of this invention is to provide a. light fixture of the class described, which may be made in various designs such as that of the Kewpie doll, Lily doll or in any other desired form.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined b the appended claims, it being understo that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete examp e of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the rinciples thereof, and in which:

Figure 1 is a front elevational view of a lamp fixture, embodying my invention, the lam base or support proper being molded in t e form of a ily doll;

Figure 2 is a fragmentary top lan view, looking at the lamp receiving socliet on the plane of line 2-2 of Fi re 3; and

Fig. 3 is a section on ine 3--3 of Fig. 2.

Figure 4 is a fragmentary view, taken throu h the head end of the improved form of m0 (1 I emdploy in constructing li hting fixtures embo ying my invention, said view being part in section and part in elevation.

Referrin now more particularly to the accompanying drawing in which like numerals designate like parts throughout the several views: The numeral 5 designates generally the body portion or supporting base of my new, improved device, which in the present in stance is the form of a doll havm the improved form of lamp receiving soc et, hereinafter described, in which is removably secured an electric light globe 6.

The body 5 is formed of plastic material, which is poured in a two part mold 7, which has the end Walls thereof, forming the head 8 recessed or counter bored as at 9, and provided with an opening 10 communicating with said recess and adapted to have a terminal plug 11 projected thercthrough into the interior of the mold. The pin 11 is of conventi ii construction and, prior to its insertion z mold, has an internally and externally thread-ail. metal sleeve 12 preferably of copper, screwed thereon to lie within that portion of the mold defined by recess 9.

Prior to the final insertion of the plug 11,

with the sleeve 12, into the mold, one end of Y a wire 13 has the insulation removed therefrom and secured to the sleeve 12 by twisting the same therearound as at 14 and a wire 15 has the insulation removed from one end which is secured to the plug 11 by the usual center terminal screw 16 thereof. In securing the end of wire 15 by the screw 16, said screw is only partly driven home and the wires 13 and 15 are then strung central] through the mold as illustrated in Fi ure After the mold has thus been set, t e material is lpoured therein and when suificiently hardene the plug 11 is unscrewed. By

- cured in lace, the same wi but looselysebe readily unscrewed m the log 11 and when it is completely removed om the. mold, leaving the sleeve 12 in lace the screw 16 is dlseng'aged from the en of the wire 15, thus leaving the bared end 17 for engagement with the central terminal 18 of the globe 6 the other side terminal of which contacts with the socket 12.

The finished article has a projection or boss 19 formed thereon b the recess 9 1n the mold which boss provi es ready means of attachment for a support 20 for a suitable shade 21 Support 20 has a lower split ring 22, which engages about the boss 19, and is finally clampe or secured thereto by the binding means 23.

From the foregping description taken 1n connection with t e accompanying drawing it will be readily apparent that I prov de a lighting fixture m w ich the lamp rece ving socket is formed in an inexpensive manner and at the same time gives the desired results and roduces a fixture of ornamental and. pleasing appearance.

What I claim as my invention is:

1. As an article of manufacture,.a lighting fixture molded of plastic non-conducting material, an internally and externally reason of the screw 16 beinfi threaded open ended metallic sleeve set in the fixture at its time of molding to provide an electric lamp receivin socket, an electric feed wire having one on twisted about the exterior of said sleeve to have an electrical connection therewith, and a second electric supply wire havi one end projected into the s ace within said sleeve to provide a contact or one terminal of the lamp, the other terminal of said lamp contacting with said sleeve.

2. As an article of manufacture, a li htingfixture' moulded of plastic non-con ucting material, an open ended internally threaded metal bushing set in the fixture at its time of moulding to form a lamp receiving socket, an electric wire electrically connected with said sleeve prior to the moulding of the fixture, and a second electric wire having its end terminatin in said socket, said second wire bein% set in place prior to the moulding of the xture and insulated from the other wire by the material forming the fixture, the bushing forming one terminal for a lamp secured m the socket and the end of the second wire forming a terminal for the lamp.

In testimony whereof I aflix m si ature.

CHARLES F. EC ART.
