To all whom it may concern:

Be it known that I", JOHNIi. RInDLE, a citizen of the United States,residii 1gat Toledo, in the county of Lucas, State of Ohio,' have invented a certain new and useful Improvement in Lighting'lfixtures, Which the following is a specification.

l\[y invention relates to the. construction described 'in my co-pending application, Serial No. 7205885, and has for its object to provide a d ifierent form of lighting fixtures which can be assembled ithout the necessity of employing any machine Work irrtheir construction, and to, accomplish that result by means which will permit-'01? the production of a highly: ornamental fixture. It will not require any skilled labor in its assembly;

means of accomplishing the foregoing objects may be more readily understood by reference to. the accompany drawings, in which Fig; 1 is. an elevation of a fixture constructed in accordance with my invention part oftlie: exterior being broken. away to show the interior construction- 1 Fig. 2 is a cross-section takenojn lthe line in Fig. 1. I

Fig. 3 is a .crossrsection taken on the line.

Figs. iand. 51 are top and side detail. View. oi arms.

Figs. '6 and notched disc.

Fig. .8 is a. detail View of the conoidal member.

Fig. .9 is a detail view of the securing disc.

Fig. 10 is a deta'l view of the central spindle.

Fig. 11 is a detail view .of the ornamental covering for the central spindle. I

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

As shown in the drawings, the lighting fixture comprises a central spindle .Lwhich is provided with threads .2'a11d 3 at its lower and upper ends, respectively; A nut l is mounted upon'the threads' Ql at thelower end of the spindle. Uponthis restsl a spider 5, which is provided Witha plurality of outwardly extending branches 6 terminatingin sockets 7 to whichmay be securedthe Gl e are detail views of the tric lights. These branches are channeled,

as clearly seen in Figs. land 3.

h n es 6 r Pro ded. w th. 9e1 tra-l recess 32 in which" ifs-mounted a colloia memb r- 5%, wh h i erred. w th a di cumierentia l flange 9,? and shoulder "10',

which is fitted to andextendedi intoi the central recess 32 in the bodyportion s p i'dfer:

The conoidal portion 8 is proyided With at a central opening 11 at itsf upper through which the spindle l extends.

The, spindle l'i's inc'losed in an ornamental coveriiig 12; which extends froni'the of the conoi'dal member 8 tot a notched disc 13.. This disc,' as clearly seen in Figs. 6 and 7"has a peripheral flange'- 14t i1 1' which are formed a plurality of notches 1 5].

A plurality of armslfi in numbercorre spending "to the number otbrariclies 6,a-re then mounted upon the branches 6. These a-rms'16; as clearly". seen in. Figs: and 5 are provided with downwardly eitendirng lugs.

17, which enter the channelsjin the branches 6 at a'point adjacent, thewa'll of the central recess, thereby completing this. Wall. 'The curved portion 1 8o fithe arn'ientersthe channel, dearly seen in Figs: rand 8. This serves to hold the arms against-any latterly displacement. The lawyer end' ef "the arln is then curved inwardly and-u wardlyfor'minga foot 19; the inner'Wal-l' o-fwhi'ch is fitted to and coincides'yviththe surfaceof said conoida-l member S; The upper end 20' of the arm '16 is provided With an inwardly extending lug 21 which fits the slots'ldi'n the. notched diso 1-3. -The s'ide of the wings 22. and -23 -adj'ace11't the Wall of the. notched disc. are formed on an arc of .the same radius as the innerfsuriace ofth'e, peripheral flange 14 of the notched. disc, 135x Above this notched discis mounted a se curing disc 25 .Which is, proridediiwith .a shoulder 26, which engages; the inwardly extending lugs-2.l, the flattened .portion27 resting upon the top of the saidlugs. .The. securing disc .25 is provided .With, an up- Wardlyextending portion 28, Whichisfengaged by the bottom of loop 2.9., which is mounted upon the threads 3. on the, upper endof thespindle 1.

The fixture is assembledinthe following manner: The nut 4 is fitted to the thresd 2. on the p i l p n th s i en'meuhtedflm spider 5, the Wires 30 are then brought throught-he center of the spindle and to a hickey 31, of standard construction, whence they are carried out through the channels in the branches 6.

The conoidal member 8 is then placed in position, the shoulder 10 serving to hold it in position by engagement with the walls of the recess 82. The ornamental covering 12 is then placed in position. This serves to hold the spider and notched disc in spaced relation. The notched disc is dropped over the spindle 1 and rests upon the ornamental covering 12. The arms 16 are'then placed in position by fitting the inwardly extending lugs 21 to the notches 15 in the notched disc 13. Thelower curved portion of the arms16 is placed in the branches 6, the lugs 17 entering into the channels in the branches 6, the lower curved portion of the arms also extends into the channels of the branches 6 and the foot 19 rests upon the outer tapered wall of the conoidal shaped member 8.

The securing disc is then placed upon the spindle 1, the shoulder 26 serving to hold the wings tightly in engagement with the peripheral flange 14 in the notched disc, the flattened portion 27 preventing the lugs from moving upwardly and out of the notches. The loop 29 is then screwed upon the threads 3, and this serves to draw the parts together. The walls of the conoidal number 8 being tapered it is obvious that the more the loop is screwed down the tighter the foot 19 will be pressed against this conoidal member 8, and the more securely and rigidly the fixture will be held together. 7 K

It will be apparent from the foregoing description that there is not one particle of machine work required to assemble this fixture, with the exception of the threads on the spindle and the nut and loop there is no first-class machine work on the entire fixture.

The result ofthis construction is that 1 am able to provide a highly ornamental fixture at a very low cost of construction, and it will be obvious that the construction is not limited to the specific ornamental structure employed, but on the contrary a very wide number of designs can be made,-- all of which will utilize my means of assembling, whereby the skilled labor required to manufacture a fixture can be done away with, and I do not desire to be understood as limiting myself to the specific details of construction or ornamentation, as obviously they form no part of my invention, and are spindle, a spider mounted at the lower end thereof, channeled branches on said spider, there being a central recess in the body portion of said spider, a conoidal shaped member mounted in saidrecess, a plurality of curved arms, lugs formed on said arms adjacent their lower ends, an inwardly extend- 7 ing foot portion on said arms fitted to the outer surface of said conoidal member, a notched disc at the other end of said spindle, lugs at the upper end of said arms which engage said notches, a securing disc on said spindle above said notched disc, a nut on each end of said spindle whereby the parts can be drawn tightly together and held rigidly in place.
