United States Patent 3,159,351 LIGHTING FIXTURE Anthony A. Dwyer, 332i) Wonderview Drive, Los Angeles, Calih; Lloyd L. Garnell, 8029 Coldwater Canyon, North Hollywood, Calif.; Norman (1. McClay, 1430 Elm Ava, Glendale 1, Calif.; and Ray Sealoclr, 2313-(1 Burbank Blvd, Burbank, Calif.

Filed Nov. 3, 1961, Ser. No. 150,083 3 Claims. (til. 240-40) Our invention relates to improvements in lighting fixtures for interior or exterior decorative and ornamental use, in or around commercial or residential buildings, or elsewhere.

It is an object of our invention to provide a lighting fixture which can be used to create decorative and ornamental effects for many purposes.

Another object of our invention is to provide a lighting fixture having a design which can be manufactured readily in large quantities and at a relatively inexpensive cost.

A further object of our invention is to provide a lighting fixture which can be sold to consumers in large quantities in a disassembled condition for easy and quick assembly by consumers.

These and other objects of our invention will be more readily understood by reference to the following description and claims, taken in conjunction with the accompanying drawings forming a part hereof, in which:

FIGURE 1 is a plan view of an ornamental reflector plate member which is supported in position by the lighting fixture.

FIGURE 2 is a side elevational view of the lighting fixture with a reflector plate, shown in section.

FIGURE 3 is a view taken along line 33 of FIG- URE 2.

FIGURE 4 is a view taken along line 4--4 of FIG- URE 3.

FIGURE 5 is a view taken along line 5-5 of FIG- URE 3.

FIGURE 6 is an exploded view of the lighting fixture showing the various elements.

In the construction of the lighting fixture 10, the light bulb 12 is threaded into an electrical socket 14 which is supported by the cylindrical mount 16. A protective cylinder 18 surrounds the lower part of the light bulb and is attached by screws 20 to the mount 16. Electrical wires 22 contained in the conduit 24 connect the socket 14 to a source of electricity (not shown).

An outer step down member 26 made up of a plurality of concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes with openings 27 for cooling and for transmission of light surrounds the upper part of the light bulb and is fixed in position to the protective cylinder 18 by adjustable clamp 28. An inner transluscent step down member 29 made up of a plurality of concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes fits inside the member 26 and is held in position by clip members 30 attached by screws 31 to the lower portion 32 of member 26. The inner member 29 may be made of suitable plastic or other material in various colors. An 'O-ring seal 33 provides sealing of the inner member 29 to the outer member 26. A re flector plate 34 having a top element 34' is secured at 36 to the outer end of the member 26.

3,159,351 Patented Dec. 1, 1964 ice All of the parts of the lighting fixture 10 as well as the reflector plate 34 may be made of any suitable material, such as various metals or plastics. Any type of reflector plate may be used in conjunction with the lighting fixture. The reflector plate shown in the drawings is illustrative only.

In the operation of the lighting fixture, it may be placed wherever a source of electricity is available. When the light bulb 12 is lighted, rays of light come out of the openings 27 and illuminate the reflector plate 34. The heat produced by the light bulb 12 is sufliciently dissipated through the openings 27 which provide cooling suflicient to prevent any deformation or deterioration of the materials used to construct the lighting fixture.

While we have described our invention in detail with reference to the accompanying drawings illustrating the preferred embodiment of our invention, it is understood that numerous changes and arrangements of parts may be made without departing from the spirit and scope of the invention as hereinafter claimed.

We claim:

1. A lighting fixture comprising an electrical socket having a light source, a stationary translucent inner member surrounding the light source and made up of a plurality of concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes, a stationary outer member superimposed on said inner member and made up of a plurality of concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes and having a plurality of openings in the sides of the smaller tubes and an opening at the top of its narrower end, both of said inner and outer members having their wider ends closer to said socket and their narrower ends closer to the light source to concentrate the light from the light source.

2. A lighting fixture comprising an electrical socket having a light source, a stationary translucent inner member closely surrounding the light source and made up of a plurality of symmetrical concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes, a stationary outer member closely superimposed on said inner member and made up of a plurality of symmetrical concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes, and having a plurality of openings in the sides of the smaller tubesv and an opening at the top of its narrower end, both of said inner and outer members having their wide rends closer to said socket and their narrower ends closer to the light source to concentrate the light from the light source.

3. A lighting fixture comprising an electrical socket having a light source, a stationary translucent inner member closely surrounding the light source and made up of a plurality of symmetrical concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes, a stationary outer member closely superimposed on said inner member and made up of a plurality of symmetrical concentric cylindrical tubes having horizontal flanges connecting the ends of adjacent tubes, and having a plurality of openings in the sides of the smaller tubes and an opening at the top of its narrower end, both of said inner and outer members having their wider ends closed to said socket and their narrower ends closer to the light source to concentrate the light from the light source, and reflector plate means closely superimposed on said outer member and having a plurality of spaced plates joined together;said"plateshaving suflicient space between them to allow passage of light from the openings of said outer member.
