Specification of Letters Patent.

Patented Jo a, 1918.

Application filed August 14, 1916. Serial No. 114,672.

Be it known that I, Hmmir DOLIER, J12, a citizen of the United" States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Light-Distribution Charts, (Case A,) of which the following is a specification.

This invention has for its object to provide a light distribution chart which shall display, 1n connection with a set of representations of lamp wattage, a set of repre sentations of reflectors, and a set of representations of results obtainable, 6., indications of difi'erent degrees of light concentration and direction, said representations being so arranged as to display, at the intersection of imaginary lines extending throu h a representation of lamp wattage firough a representation of a result; a representation of the special reflector which, when used in connection With the lamp Wattcated, z. 6., a special concentration and direction of rays of light, and may also display information indications of anIyl charwords, my novel chart enables the user to select at a glance the proper 1am and reflector to produce, when combine any required concentration and direction of rays oflight. a A

With the above. and other objects in View,

' I have devised the novel light distribution i chart of which the following description in connection with the accompanying drawing 1, is a specification, reference characters being used to indicate the several 'parts:

. The drawing is a plan view of a portion of a light distribution chart'embodying my novel invention. 7 j

10 denotes a card, sheet or'folde'r, which for convenience I will term the sheet, and

which may be made of any suitable material, 7

as celluloid, paper or textile material and of any preferred shape, as round or angular. By preference, although not necessarily, the sheet is divided, by lines crossing each other at right angles, into squares. 11 denotes a set of representations of lamp wattage; These representationsmay be in the form of pictures of lamps or of statements of wattage, as for example-100 watt, or both pictures and statements may be used, if preother ferred, as shown in the drawing. As 10, 15 and 20 watt lampsare substantially the same in configuration and arrangement of fila- '500 watt lamps are shown, as these lamps differ more or less in configuration and in the arrangement of the filament.

12 denotes a .set of representations of results obtainable in the concentration and direction of rays of light. These representations maybe in the form of diagrams indicating difi'erent degrees of light concentration, or of words indicating different degrees of light concentration, as angle, distributing, extensive, intensive, focusing, &c., or both diagrams; and words may be used if preferred, as shown in the drawing. In connection with these representations of results obtainable, I may or may not use letters and figures indicating the mounting height of the lamp above the workin plane. For example, the working plane is or inarily figured as two feet, six inches above the floor, and a'standard mounting height, indicated by M, may be arbitrarily fixed at eight feet above theworking plane, and the figures used in connection w th the letter M indicate the degree of concentration of the rays of light at the working plane, thus ment, I have grouped them together. Indev I M2 indicates that a lamp in a definite type of reflector eight feet above the working plane will evenly illuminatethat Worln'ng plane over thexarea of a circle sixteen feet in diameter, the center of the circle being directly under the tip of the lamp hanging pendant. If greater intensity of light is required, another type of reflectormust be used, which will produce even illumination over a smaller area; thus, M-l} indicates the workin plane over the area of a circle six feet in iameter, i. e. three-fourths of the standard mounting height.

means that the fixtures are Hubbell fixture-s M means porcelain enamel; X means angle position; D means distributing; I means intensive; E means extensive; F means focusing; A means aluminum finish; the number indicates the wattageof thelamp; and L, following the number, means heel extension; thus. H)IE'500L would indicate Hubbell fixtures, porcelain enameled, with 'an extensive type of reflector on a 500-watt lamp with a heel extension.

The use of my novel chart is as follows: Having determined the lamp wattage to be used, and the'result, i. e. the light concentration required, as indicated by a representation of a result, the operator traces an imaginary line inward from the selected representation of lamp wattage'and from the selected representation of a result, and at the intersection of said imaginary lines will be found a picture or representation with accompanying information indications showing the reflector required to produce-the desired concentration of light from the lamp selected. For example, suppose that a 100 watt lamp is to be placed ten feet above the desired to illustrate.

working plane and that an aluminum finished reflector giving intensive concentration of lights is required, the operator traces an imaginary line inward. from the representation of lamp wattage specifically indi-' cated by a and from the representation of a result indicated by b, and at the intersection of said imaginary lines he will find a picture or representation of the reflector, specifically indicated by a, required to produce the desired result with the selected lamp. It will of coursev be understood that the size of the chart islim'ited only by the number of repfesentations'of lamp wattage, results obtainable and reflectors that it is For the purposes of this specification, I have illustrated a limited number only of representations of lamp wattage, results obtainable and reflectors. It

. will furthermore be understood that, the

sizes and styles of lamps are standardized and that the reflectors are scientifically designed to produce predetermined results from standard lamps. 'By the use of scientifically designed reflectors. properly located with relation to the lamp filament. the light from the lamp is re-directed so -as to cause These representations of reflectors a surface or working plane to be evenly illuminated over a known area, the area depending of course upon the type of reflector and the height of the lamp above the working plane.

Having thus described my invention, I

will be indicated at the intersection of right angular ly disposed imaginary lines leading from any of the indicated hght intensities and the selected indlcatlon of light concentrat-ion.

2. A chart of the character described comprising a row of indications of different light concentrations, a row of indications of different light intensities arranged at right angles to the row of light concentrations,

and a plurality of rows of indications of devices for obtaining the various indicated light concentrations when employed in connection with the different indicated light intensities, said indications of devices being so arranged that a device capable of producing a selected light concentration will be indicated at the intersection of right angularly disposed imaginary lines leading from'any of the indicated light intensities and the selected indication of light concentration.

3. A chart of the character described comprising a vertically disposed set of different light concentrations, a horizontally disposed set of indications of different light intensities, and a plurality of horizontally disposed sets of indications of devices for ,obtaining the various indicated light concentrations when employed with the difierent indicated light intensities, the sets of in dications of'devices being arranged in alinement with the respective indications of light concentrations and indications of light intensities, whereby a device capable of producing a selected light concentration will be indicated at the intersection of right angularly disposed imaginary lines leading from any of the indicated light intensities and the selected indication of light concentration.

4. A chart of the-character described comprising a set of indications of ditferent fixed light concentrations, a set of indications of different fixed light intensities. and a pluralityof indications of devices for obtaining the various indicated light concentrations when employed with the different indicated being so arranged that a device capable of fixed light concentrations, a set of indications of diflferent fixed light intensities, and

' a plurality of indications of devices for obtaining the various indicated light concentrations when employed with the difierent indicated light intensities, said indications of devices being so arranged that a device capable of producing a selected light concentration will be indicated at the intersection of right angularly disposed imaginary lines leading from any of the indicated light intensities and the selected indication of light concentration, and means for indicating variations in the fixed formof the devices to be selected.

6. A chart of the character described comprising a set of indications of difierent fixed light concentrations, a set of indications of difi'erent fixed light intensities, and a plurality of indications of devices for obtaining thevarious indicated light concen-. trations when employed with the dlfierent,

indicated light intensities, said indications of devices being so arranged that a device capable of producing a selected light concentration will be indicated at the intersectionl of right angularl y disposed imaginary lines leading from any of the indicated light intensities and the selected indication of light concentration, means for indicating variations: in the fixed light concentrations, and means for indicating variations in the fixed form of the devices to be selected.

In testimony whereof I aflix my signature.
