REFLECTING- LAMP SHADE AND GLOBE.
Application filed December 20, 1918.
To all whom it may concern:
Be it known that I, ERNEST MALCOLM BEN- NETT, a subject of the King of Great Britain and Ireland, residing in the city of Prahran, a suburb of the city of Melbourne, in the county of Bourke, State of Victoria, Commonwealth of Australia, and whose postoffice address is 115 Union Street, WVindsor, in the said city of Prahran, have invented certain new and useful Improvements in Reflecting Lamp Shades and Globes, of which the following is a specification.
This invention relates to globes and shades for use with electric incandescent or other lamps and its object is to provide a reflecting globe or shade which will materially increase the illuminating effect of the lamp by reflecting and refracting the light rays in such a manner that their maximum value is availed of and a brilliant result is obtained.
The invention is particularly advantageous for display purposes such as the illumination of buildings, showcases, window fronts, and such like positions where brilliant effects are desired.
The invention consists essentially in forming a shade or globe of transparent glass the exterior of which is silvered or otherwise treated to produce a reflecting surface, while the interior of the shade is provided with a series of jewel shaped or multi-sided projections having inclined facets which are arranged to distribute or refract the reflected rays from the lamp or illuminating agent to various different directions thus greatly increasing the brilliance and effectiveness of the light.
Referring to the drawings which form part of this specification Figure 1 is a view of a shade constructed in accordance with the invention portion being broken away to illustrate one form of the refractive projections on the inner face of the glass.
Fig. 2 is a plan of Fig. 1 portion being broken away to illustrate the cross sectional contour of the projections.
Fig. 3 is an enlarged view of portion of the internal face of the shade seen in Figs. 1 and 2.
Fig. 4 is a view of another form of shade or globe in which the internal projections are of pyramidical form with straight or flat sides.
Specification of Letters Patent.
Patented Sept. 28, 1920.
Serial No. 267,626.
Fig. 5 is a plan of Fig. el part being broken away.
Fig. 6 is an enlarged view of portion of the interior face of the shade or globe seen in F 4 and 5.
Fig. 7 is an enlarged vertical section of portion of a shade showing the concave formation applied to the pyramidal projections.
Fig. 8 is a section on line A-A of Fig. T.
In accordance with the invention the globe or shade is formed of transparent glass of any desired shape, design or color.
The outer surface 2 of the glass is plain or smooth and to it is applied by any well known means a suitable reflecting agent such as quicksilver. A particularly suitable formula for this preparation is as follows (a) Nitrate of silver175 avoirdupois grains, distilled water 10 ELVOilTlLlPOlS ozs; (b) nitrate of ammonia-262 avoirdupois grains, distilled water 10 avoirdupois 02s.; (0) pure sugar candy-J avoirdupois oz., distilled water 5 avoirdupois 025.; (d) tartaric acid-50 avoirdupois grains, dissolved and boiled in a flask for ten minutes and when cool 1 avoirdupois ounce of alcohol and distilled water sufiicient to make up 10 ounces added.
For use equal parts of (a) and (Z)) are mixed together, and equal parts of (c) and (d) are mixed in another measure. These two mixtures are then intermixed in the silvering vessel.
The shade or globe after being carefully cleaned with soda and well rinsed with clean water is suspended with its outer face downward in the silvering solution where it is allowed to remain for from 20 to 80 minutes according to weather conditions. The shade is then withdrawn and the silvering solution allowed to dry thoroughly on the glass.
After the outer surface of the shade has been thus treated I preferably apply a protective outer coating or backing of suitable material such as an elastic varnish. A suitable preparation for this purpose may be formed by dissolving and mixing together the following ingredients:
Dammar gum 10 parts Asphalt 3 parts Gutta percha 5 parts Benzol parts This solution is poured over the silvered surface of the shade which is then moved to 'and fro until the varnish is distributed evenly over the whole surface.
above or any other means, the shade is provided on its interior with a series of projections 8 which protrude inwardly toward the center of the shade. These projections may be of any suitable design or contour such for instance as shown in Figs. 1' to 3 where they are formed of a diamond or jewel shape having flat truncated surfaces or tables indicated at 4: and a multiplicity of inclined sides or facets 6 which are adapted to refract or distribute the reflected rays from the lamp in various different directions. The inclined sides or facets may be plane, or they may be of concave formation, the latter construction being illustrated in Fig. 3.
Another example of the shape which the projections 3 may take is shown in Figs. 4, 5 and 6 where they areof a plain pyramidical form and provided with inclined flat sides or facets which may be plane, as represented at 7 in saidfigures, or of'concave formation, as indicated at 8 and 9 in Figs.
7 and 8.
In Figs. 7 andS the silver or reflecting medium is indicated on the outer plain surface of the glass by the numeral 10 and the varnish or other protective backing is indicated at 11 to clearly show the relative features of the invention.
13y thus treating a transparent lamp shade or globe a highly effective and brilliant result is obtained. The rays from a lamp thus inclosed are reflected back by the outer reflecting surface of the shade and then thrown out in a variety of directions by the inclined sides or facets of the projections 3 thus greatly enhancing the illuminating power of the lamp. The inventionfurthermore does not greatly increase the cost of production of the shade or globe which may obviously be made in an size, shape or color required. 1 v
Having now described my invention what I claim as new and desire to secure by Let ters Patent is V l. A lamp shade or globe of transparent glass, having a reflecting medium covering its exterior surface, and provided on its interior with integral, inwardly extending jewelshaped projections having flat, truncated surfaces or tables and a multiplicity of inclined sides or facets, saidsides or facets being of concave formation.
2-. A lamp shade or globe of transparent glass, having a reflecting medium covering its exterior surface, and provided on its interior with integral, inwardly extending multi-sided' projections, the sides of said )rocctions hein of concave formation. t:
In testimony whereof I ailix my signatur E. M. BENNETT.
