LAMP STAND FOR SHOWGASES.

""' Application filed December 26, 1922.

To all whom it may concern.

Be it known that I, Fnupnmo L. WHEELER, a citizen of the United States, residing at Berkeley in the county of Alameda, State of California, have invented a new and useful Lamp Stand for Showcases, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a lamp stand for show cases, and its object is to provide a lamp stand which will properly illuminate the materials in a show case without unduly heating the show case.

It will be understood by those skilled in the art that where lamps are used either inside or outside a show case that ordinarily the heat generated will become so great as to cause the glass of the show case to crack Very readily if chilled too quickly.

With the present invention the stand con taining the lamps is really a concealed illuminating device and the upper portion of the stand carries other lamps which give an artistic effect to the stand, while at the same time providing the necessary chimney to ventilate the base in Which the show case illuminating lamps are contained.

Another object of the invention is to illuminate show cases from the outside to avoid overheating the objects displayed in the show cases.

Other objects of the invent-ion will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the. same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

Fig. 1 is a vertical sectional view of the complete lamp stand without the lamp cord being shown,

Fig. 2 is a bottom plan view of the lamp stand base,

Fig. 3 is a sectional view of one form of reflector surface used to disperse the light in a show case.

The numeral 1 indicates the base of the lamp stand, which is of any desired shape, in the present instance the lower portion of the base having twelve reflecting surfaces provided with corrugated glass mirrors 2. This base is raised above the glass top of the show case 3 by means of four feet, 4: to 7 inclusive.

Adjacent the center of the base 1 there Serial No. 608,862.

is a raised portion 8 having any suitable curvature and being provided with a suitable reflecting inner surface.

This raised portion 8 carries two

lamp sockets

9 and 10 in which elongated

show case lamps

11 and 12 are placed. These lamps are held in place at their ends by means of

spring clips

13 and 14 secured to the inside of the lamp base.

A tubular member 15 extends upwardly from the raised portion 8 and supports lamp sockets 16 and 17 in which lamps 18 and 19 are placed and any suitable shade 21 is carriefl by the tubular member 15 at its upper en In operation the lamps 18 and 19 are simply used to lend effect to. the stand and are ordinarily lighted only when the store happens to be rather dark, but the

lights

11 and 12 are lighted whenever it is desired to illuminate objects under the show case glass 3, and since the inside of the base is of more or less corrugated reflecting surface, the light is diffused downwardly onto objects in the show case.

The heat generated by the

lamps

11 and 12 causes an upward draught of air in the tube 15 and this draught keeps the show case glass cool enough so that there is never any danger of cracking it.

What I claim is as follows, but various modifications may be made in the construction shown in the drawings and above particularly described form, within the purview of my invention.

1. A lamp stand having a base, a series of lamps therein, a hollow standard open at top and bottom to allow theheated air to escape therefrom, and lamps supported at the top of said standard.

2. A show-case lamp, comprising a hollow base having reflecting surfaces formed on its interior, a lamp within said hollow base, a hollow standard open at top and bottom to allow the heated air to escape therefrom, extending upwardly from the base, lamps carried by said hollow standard at its upper end, and a lamp shade extending over the lamps at the top of the hollow standard.

3. A lamp stand for show cases, compris ing a hollow base having its interior surface light reflecting, a series of lamps within the base, a hollow standard open at top and bottom to allow the heated air to escape therefrom, lamps supported: at the top of the standardand a vshade for concealing said lamps.

4:. A show case lamp, comprising a hollow base formed with reflecting surfaces on its interior, oppositely placed lamps supported Within the base, a hollow standard open at top and bottom to allow the heated air to escape therefrom, extending upwardly from the base and opening thereinto, lamps.

carried by the standard at its upper end, a

shade extending over the lamps at the top of the standard and means to permit a free Circulation of air from the lamp base through the hollow standard to preYent overheating the show case.

In. testimony whereof I have hereunto set my hand this 11 day of December A. D. 1922.
