LIGHTING FIXTURES Filed Jan. so, 195e This invention relates to lighting fixtures: i

One of the objects of this invention is to providefa lighting fixture which is yvertically positioned and has means for engaging the floor and ceiling ofthe room to support said fixture. n e

Another object of this invention is to provide a verti cally positioned lighting fixture which is supported umV der tension and engages the floor and ceiling of the room and which permits a plurality of lights to be supported at a plurality of different elevations and' in various circumferential positions and which lights may be directed for direct or indirect lighting. n

Another object of this invention is to provide a lighting fixture unit which is vvertically positioned-and held in a fixed position by engagement under tension with the floor and ceiling of the room and is provided with aplurality of detachable sections to accommodate any ceiling height.

This invention has many advantages over floor or table lamps in that it is secured so that it cannot be accidentally dislodged or overturned. It permits the staggering or spacing of the lights at various elevations along the length of the unit, as well as circumferential spacing thereof so that each light beam may be individually and independently controlled and directed at any desired object. It also permits the same light source to be used for direct and indirect lighting.

Another object of this invention is to provide a lighting fixture of the foregoing character which is ornamental and very attractive and which is'economical and inexpensive to manufacture.

Other objects will become apparent'as this description progresses. .a

In the drawings: u

Fig. 1 is an elevational view showing the lighting fixture supported and maintained under pressureV between a floor and a ceiling.

Fig. 2 is a cross-sectional view of the lower portion of Fig. l.

Fig. 3 is an enlarged cross-sectional view showing particularly the upper section of the pole.

Fig. 4 is `a cross-sectional view of amodified form of bracket.

Fig. 5 is a view showing another form of arrangement of lighting elements, and

Fig. 6 is a top plan view taken from the top of Fig.` 5.

As shown in Fig. 1 the lighting fixture is formed of' four tubular sections designated by the numeral-s 10, 11, 12 and 13 which are joined together, as will be described, for the purpose of providing a singular tubular pole. Due to the difference in ceiling heights it may be necessary to reduce the length of the pole, consequently one of the tubular sections, for example, vsection 11 may be eliminated and section 10 may then be secured to section 12, or if a longer tubular column is required additional sections similar to that of section 11 may be added.

The lower tubular section 13 has a circumferential flange 14 and supports a washer 16 which is secured thereto. The washer 16 has a threaded opening 18 which f nited States Ifflteifl 4lili threadedly receives a threaded stem or yleg 20, the outer end of which has secured to it a circular disc 21 provided with a felt or rubber covering 22. The leg member 2t) is therefore adjustable with respect to the tubular section 13. The upper end of section 13 v(Fig. 2) is open and is provided with `af` reduced circumferential portion 24 which nests intosection 12 and is held in friction-tight fit1' therewith. A fshoulder 26 on section 13 limits the nesting fit between section 13 and section 12.

The upper open end of section 12 is adapted vto receive the reduced circumferential portion 28 of section 11 which is likewise provided with a. shoulder 29. The upper open end of section 11`is` adapted to receive the reduced circumferential portion 30 of section 10 in frictionahtight engagement. A shoulder 31 is provided `on section 10. The 'upper 'endr'of 'section 10'hasa circumferential flange '34. A`washer-36 isseured in the -upper end of section 10 against' said flange andjsaidwasher ha-s a central opening 37 which slideablyreceivesra rod 38 which extends into the tubular section 10. The oppositeor lower end of section 10 has a circumferential flange 40 which supportsa' washer 42- whichwasher thas an opening 44 in alignment with opening 37 and through which the rod 38 extendsexteric'irlyv of section 10.

Securedtolthe ro'd 38 inside section 10 is inverted cup shaped Washer 46 and a pin 48. A coiled spring 49 is positioned'inside said tubular. section 10 surrounding said rod 38 and between thewasher 46 secured to the rod and thei'washer42 on section 10 and normally urges the rod. 38 upwardly V-as shown in Fig. 1.or` outwardly of said tubular-section. The rodfis prevented from being withdrawn'outwardly of said tubular section by the pin a Secured to the outer -end of the rod is a disc 50 to which is secured a felt or rubber covering 51. When the sections 10, 11, 12 and 13 are joined together to form an integral post, as shown, the lsections are frictionallyheld together as' a unit, however, they may be disassembled if necessary. The unit as shown is 'supported vertically between the floor, designated by a letter F and the ceiling designated by the letterC and the rod 38 is urged upwardly of section 10 to rest again-st the ceiling and to hold the pole in a fixed position under tension or pressure against overturning or accidental dislodgment; The leg 20 is also adjustable by merely rotating same with respect to the lower tubular section 13,

`thus there is provided an adjustable lower leg and an 12 which would beone section above the lowermost section 13 for the reason that section 12 would position the lighting fixtures at thedesred height. Furthermore, it would not interfere with the sliding movement of rod 38. As shown in Fig. l, section 12 is provided with three lighting fixtures and while three are shown any number of lighting fixtures may be suitably arranged on said section at different desired elevations and they are spaced circumferentially around said section. The lighting fixtures which are all designated by the numeral 54 each has a bracket 56 (Figs. 2 and 6) having a threaded nipple 57 which fits into an opening in the section 12 and is secured thereto by a threaded nut 58 which locks said bracket to the section '12. The bracket is bifurcated as at`59, as best shown in Fig. y6, to receive the extension 60 secured to the shadel62 of the lighting fixture. A pin 63 secures said extension to said bracket for swiveling action. The lighting fixture is lprovided with the usual electrical socket which receives a light bulb around which is -supported the shade 62 heretofore mentioned.

The shade 62 and light bulb supported therein may t Paiented May 21,l las?"T be adjustably positioned to direct the light beam whenever desired by swiveling same on the pin 63 and may also be rotated by rotating bracket 56 so that the light may be directed to the ceiling or floor for indirect or direct lighting or in any other direction as desired. An electrical insulated conducting wire 64 connects the various lighting fixtures 54 and said conducting wire extends through the tubular section 12 and is connected to a switch 66 secured to the lower end of section 12. Said conducting wire extends downwardly through section 13 and outwardly thereof and is electrically connected by means of the usual plug to a source of electric current. The conducting wire passes through the nipple 57 and bracket 56 and is secured to the socket positioned in the shade 62.

By operating the switch 66 the lighting fixtures 54 are turned on and off as desired.

Fig. 4 shows a modified bracket for supporting the lighting fixture. The bracket 56a shown has a rear opening 68 which receives a short pipe 69 threaded at its opposite ends. One end of pipe 69 is connected to tubular section 12 by a nut 70 and the other end of the pipe is connected to the bracket by a washer 71 and nut 72. The remainder of bracket 56a and the manner of attaching the shade thereto is similar to that previously described. This bracket connection permits the bracket 56a to be rotatably connected to tubular section 12 so that the light may be directed for direct or indirect lighting.

The modified arrangement of fixtures shown in Figs. 5 and 6 is similar to that previously described except that the lighting fixtures 54 are circumferentially positioned around section 12 on the same elevation and are directed for indirect lighting. Any combination or arrangement of lighting fixtures may be provided as desired.

It will be understood that various modifications 'and changes may be made from the foregoing without departing from the spirit and scope of the appended claims.
