Patented Apr. 7, 1931 UNITED STATES HARRIET HEIL'E, 0F CHICAGO, ILLINOIS y LIGHTING FIXTURE Application med April 11, 1930. serial No. 443,362.
My present invention relates to improvements in lighting fixtures, and has for its object the provision of a fixture of simple construction which may be used in situations where direct and brilliant, as well as diffused eral purpose rooms, boudoirs and bathrooms,
and on occa-sion it is useful in all these situations to have at command the possibility of direct and brilliant illumination.
i It has been my object to provide a lighting fixture of simple and economical construction which may be easily adjusted to provide harmonious, diffused, subdued illumination, or to permit of the direction of the light directly and brilliantly upon the part of the area which it is desired to so directly illuminate.
I have attained the foregoing objects and results by means of the structure illustrated in the accompanying drawing, in which- Fig. 1 is a perspective of my fixture with the louvres partially opened; and
Fig. 2 is a horizontal section of the structure shown in Fig. 1 with the louvres shown nearly closed in full lines and partially opened in dotted lines.
Similar reference characters refer to similar parts in the respective views.
My l'ightingixture comprises, in part, a back or base 5 for vertical installation. The base 5 may be cemented into a wall in place of a tile or tiles, or otherwise secured to a wall or in the desired location so that it i will be disposed vertically. The base 5 is Secured to the swinging leaves of the hinges 6-'7-6 are plates or louvres 12-12 of AtranslucentYmaterial, such as ground glass or glass rendered semi-transparent in any desired way. The outer, or unattached, ver-A tical edges cf the plates or louvres 12l2 are beveled or mitred, as at 13, in order to provide an enlarged area for the plates or louvres to abut when they are in closed position, and thereby prevent the escape of beams of light between their meeting edges.
The plates or louvres 12-12 may be selected of a suitable color to transmit diffused-light of a color harmonious with the decorations employed where the light is installed.
The face 14 of the base, from which the bracket 9 extends, is, preferably, polished or silvered to provide a reflector, and, when the plates or louvres 12-12 are ground, it is suggested that the ground sides 15-15 be disposed upon the outside, as the polished interior faces will assist in throwing and directing the light when the plates or louvres 12-12 are separated.
It is also suggested that the hinges 6-6 be made sufliciently stiff to maintain the plates or louvres in the position where they are placed. It is obvious that the plates or louvres 12-12 may be made to take up a great many different positions so as to diffuse and subdue a great portion of the light or to direct the light broadly in front of the reflector 14 or in relatively narrow beams either to one side or the other of the center of the fixture.
Having described my invention what I claim as new and desire to secure by Letters Patent is:
1V. A lighting fixture comprising a vertically disposed base, the front whereof is treated to reflect light, said base having parallel, vertical edges, a bracket fixed to and extending from the refiective surface of said base, illuminating means carried by said bracket, translucent plates pivotally secured to the vertical edges of said base, said plates being of a width to meet in front of and enclose said bracket and the parts carried thereby.
2. A lighting fixture comprising a vertically disposed base, the front whereof is treated to reflect light, said base having parallel, vertical edges, a bracket fixed to and extending from the reiective surface of said base, illuminating means carried by said bracket, translucent plates pivotally secured to the Vertical edges of said base, the. opposite unattached edges of said plates being mitred and said plates being of a width to meet in front of and enclose said bracket and the parts carried thereby.
3. A lighting fixture comprising a Vertically disposed base, said base having a pair of parallel edges, a bracket liXed to and extending from said base, illuminating means carried by said bracket, translucent plates pivotally secured to the parallel edges of said base, said plates being of a Width to meet in front of and enclose said bracket and the parts carried thereby.
