1 Claim. 1

This invention relates to lamps and is P ularly adapted to floor or table lamps.

The primary object of the invention is to be able to reflect the rays of light either downwardly or upwardly exclusively, or the rays of light may be reflected in both directions to the desired proportions. This is accomplished by the using of tubular globes and by providing an adjustable reflecting element working longitudinally of these globes.

These and other incidental objects will be apparent in the drawings, specification and claim.

Reierring to the drawings:

Figure 1 is a side sectional view of my new and improved lamp, parts broken away for convenience of illustration.

Figure 2 is the locking mechanism for maintaining the reflector in adjusted position.

Figure 3 is a plan sectional view taken on line 33 of Figure 1, parts broken away for convenience of illustration.

In the drawings:

My new and improved lamp consists of a suitable pedestal I, having a housing 2 mounted thereon. Extending outwardly from this housing are hollow globe supporting arms 3, having the well knOWn fixtures 4 mounted thereon and a tubular type of globe 5 screwed therein. This globe may be a standard Mazda or it may be a neon tube. In the event it is a neon tube an upper terminal would be provided not here shown.

A shade supporting pedestal is mounted to the upper cover 1 of the housing 2 by any suitable means. Mounted to the upper end of this pedestal is a spider 8 for supporting the shade 8 at It). Slidably mounted to the pedestal 6 is a reflector supporting spider II, which has a hub l2 sliding on the pedestal 5.

Referring to Figure 2, I illustrate a means of holding this hub at any desired location on the pedestal, which consists of a brake shoe l3 maintained against the pedestal at l4 by the spring 5. The tension of the spring may be adjusted by the adjusting screw [6. Mounted on the outer ends I! of the spider II are reflectors I8 and 19. The reflectors I8 reflect the light upwardly, while the reflectors l9 reflect the light downwardly.

I will now describe the operation of my new and improved lamp. In the drawings I illustrate the reflectors adjusted for reflecting the light upwardly and downwardly, a greater amount of light being reflected downwardly. In the event it is desired to reflect the light upwardly exclusively, the spider H is lowered on the pedestal 6 to the lowest possible position. This will reflect all of the light upwardly, and in the event it is desired to reflect all of the light down this spider would be raised to the top of the globes 5, or directly underneath the spider 8. This would reflect the light downwardly. I have provided a suitable electric control switch 20, which may be of any suitable design, the same being operated by the knob 2i in the usual manner.

I do not wish to be limited to the exact mechanical structure as illustrated, as any suitable mechanical equivalent may be substituted still coming within the scope of my claim.

I claim:

A lamp comprising a vertical support provided at its upper end with a shade supporting spider, a shade mounted on the outer end of the spider, a series of lamp-carrying arms extending from the vertical support and within the confines of the shade, a series of vertically disposed elongated cylindrical lamps, extending upwardly from the outer ends of the arms, a series of reflector supports extending radially from the vertical support, means for vertically adjusting the reflector supports, reflectors mounted on the reflector supports, each reflector consisting of an upper disk with its peripheral edge turned upwardly and a lower disk with its peripheral edge turned downwardly, the disks having central aligned openings through which an elongated lamp extends, whereby light from the series of lamps will be reflected upwardly and downwardly in any adjusted position of the reflectors within the distance equal to the length of the lamps.
