LIGHTING FIXTURE.

Application filed. October 28, 1924. Serial No. 746,290.

My invention relates to that class oflighting fixtures known as chandeliers, andhas for its object to enable the production of a chandelier without the necessity of any machine work thereon, and thereby enabling the production of more artistic and beautiful fixtures without the necessity of increasing the cost of manufacture and consequent cost to the purchasing public.

My means of accomplishing the foregoing objects may be more readily comprehended by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification in which:

Fig. 1 is a fragmentary detail view taken from the top of a chandelier constructed in accordance with my improvement, part of the device being shown in section.

Fig. 2 is a side elevation of a chandelier embodying my invention partly shown in section for the sake of clearness.

Fig. 3 is a detail view of the conoidal body cover.

Fig. 4.- is a side view of the same partly broken away to show the construction.

Fig. 5 is a fragmentary detail view of the lower end of the loop.

Fig. 6 is a top sectional view of the same.

Similar reference, numerals refer to similar parts throughout the entire description.

As shown in the drawings, the chandelier comprises a spider 1, which is provided with a plurality of outwardly extending arms 2, at the extremity of which may be mounted the electric lights (not shown). In the central part of the spider are cast two screws 3 and 4t, by casting them in place the need of drilling and tapping the holes is avoided. A conoidal cap 5, which forms the body of the fixture and also acts as a cover to cover up the rough parts of the castings, is provided. This cap 5 is cast with two slots 6 and 7, and two diametri cally opposite grooves 17 and 18 are cast in the cap 5 leading from the slots 6 and 7 to the top of the cap 5. The cap 5 also has recesses 8 and 9 formed in its lower edge. These recesses register with and are fitted to lugs 10 and 11 cast or formed on the spider. The chandelier is suspended by means of a loop 12, the lower end of which is bifurcated, as clearly seen in Fig. 5, and the two forks 13 and 14: are pr0vided .with circumferential slots 15 and 16. Ihese slots are fitted to the body or threaded portion of the screws 3 and 4 but are smaller than the heads thereof.

The fixture is assembled in the following manner: The conoidal cap 5 is placed on the spider so that the recesses 8 and 9 register with the lugs 10 and 11 which obviously prevent its rotation. The forks 13 and 1st of the loops 12 are then placed in the radial grooves 17 and 18 formed in the side walls of the conoidal cover or cap. *As stated these grooves lead to the slots 6 and 7. The loop 12 is then fitted down over the conoidal cover 5, when, by tightening the screws 3 and f the loop is secured firmly in place and is prevented from slipping from uncer the lugs 10 and 11 engaging the recesses cast in the rim of the conoidal cover or cap 5. This construction greatly facilitates the casting of the parts.

It is thus apparent to persons skilled in the art that the entire fixture can be manufactured without the least necessity of any machine work thereon, and yet there is no partof the invention which necessitates the employment of any specific design for the chandelier, hence it will be understood that although I have described a specific form of construction and illustrated the same, and have even termed the one part thereof the spider, it will be readily apparent that this showing and term is only for the purpose of illustrating a concrete embodiment of my invention, butthat the same is not limited thereto, and I do not wish to be so understood, as a very wide variety of designs can be employed withoup deviating from my invention as hereinafter claimed.

Having described my invention, what I regard as new and desire to secure by Letters Patent of the United States is:

the screw heads by means of I 1. A. lighting fixture comprising a spider,

there being recesses formed in said rover which register with said lugs for the purpose set forth substantially as deserihed.

fr lighting fixture comprising a spider, having a plurality of radiating arms, screws east in said spider adjacent the eenten r snpi iortiingg nieinher having open ended circumferential slots therein which engage said serm s and means which engage said support to prevent a rotative movement thereof.

3. A lighting: fixture comprising a spider, having}; a plurality of adiatinp; arms, screws east in said Fpitltl, a lo p. the lower part of \rhieh is hit'nreated, eaten Fork at its lower end having a eireinnterential slot therein, a wonoidal eorer mounted on said spider, lugs met on said spider which engage recesses formed in the edge of aid cover, whereby a counter eloclm'ise n'iovelnent of: said loop is prevented, there being slots in said cover and grooves extending; to said slots in which the :lorlzs oi the loop are mounted.

-1L. A lighting tixtnre cmnprising a spider, screws cast in said spider adjacent the center, a loop having: circumferentia slots in the lower end thereof which engage said screws, lugs formed on said spider, a eonoidal cover niounten on said spider having: recesses which engage. said logs, the end oi said loop being titted to said cover, to prevent the disengagement of the eirennrferential slots of the loop with said SICI'G'Wf-T.
