MILTON H. SHOENBEBLG, OF SAN FRANCISCO, CALIEORNIA.
COMBINED LIGHTING AND HEATING UNIT.
Application filed December 4, 1922.
To all whom it may concern:
Be it known that I, MILTON H. SHonN- Brno, a citizen of the United States, and resident of the city and county of San F rancisco, State of California, have invented new and useful Improvements in Combined Lighting and Heating Units, of which the e the purpose of securing the best possible distribution of said energy.
Another object is the employment of a heating unit suspended from above the point it is desired to heat and a reflector behind the said heating unit by which the radiant energy emanating therefrom is directed downward.
Other objects will appear from the drawings and specifications which follow.
These objects I accomplish by mounting one of the said units within the focal range of a concave reflector and the other of said units, of which there may advantageously be a plurality about the periphery of the said reflector, positioning them in each instance so that theradiant energy received from the said units on the reflector surface is again distributed by reflection in accordance with the well known physical law? that the angle of reflection is equal to the angle of incidence to direct the reflected radiant energy downward as may be desired.
Referring to the drawings, Fig. 1 represents a combined heating and lighting chandelier employing my invention wherein the reflecting and casing elements are shown in section.
Fig. 2 is a side view similar to Fig. 1 except that the parts are shown in full.
Throughout the figures similar numerals refer to identical parts.
A suspension member is shown by the numeral 1 whereby the entire structure is supported in the desired position in Fig. 1. A reflector is shown at 2 and a secondary reflecting surface at 3. At- 4 is shown an electric heating unit energized through connections 5, 6, which also form the supporting and spacing means for the said heating unit. At 7, 8, are shown a plurality of lamps positioned about the periphery of the Serial No. 604,680.
In the construction as here shown, employing the casing 11, I prefer to support the reflector 2 by a peripheral connecting piece 15, thus preventing the transmission of excessive heat through metallic connec tions between the reflector 2 and the suspension memher'l.
The secondary reflecting surface 3 may be advantageously made of glass or other transparent or translucent substance, adapted to reflect heat rays but to permit the transmission and diffusion of light rays or a metallic or other surface 8; may be employed.
The heat rises from the heating element 4; by convection and finds a ready outlet through the passages 12, 18, as indicated by the rays 14, the passage thus forming, in effect, a chimney.
At 31 is shown a metallic ring around the opening 12 and in metallic contact with the reflector 2, the purpose of which is to form a heat radiating mass by which the otherwise high temperature of the portions of the reflector adjacent to the said opening are kept within lower limits, thus preventing to a very large degree the otherwise tarnishing of the reflector surface.
At 30, 30, 30, are shown screws which may be removed for the purpose of separating the reflecting surface 3 from the fixture to make it readily cleanable, and if desired the same screws or still others may be employed for separating the reflecting surface 2 from the fixture. In the latter case the opening 12 is to be made of suitable dimensions to freely pass over the heating unit 4. It is well known that surfaces employed for reflecting heat and the like become tarnished in practice and may require occasional refinishing and this can be best done without disturbing the other parts of the fixture by the employment of the affixing screws 30, 30, 30.
It will be seen that a part of the illumination from the lamps as 7 will follow the path 40, strike the reflector 2 at the point 16 and be reflected therefrom, as a light ray 17. Also that part of the radiant energy from from the table by the secondary reflecting surface 3; whereas the table is well illuminated by such light rays as are indicated at 22, which is dispersed through the translucent surface 3 into the rays 23, 24:, 25. This diffusion is supplementary to the direct rays as 26 and the reflected ray 17 which provides a well diffused light about the surroundings.
My fixture will therefore adequately and properly warm such a room without excessive heat concentration at any particular area and at the same time will give the desired illumination concentration where most useful. Also either the heat or the light may be used independently as desired.
The employment of the combined heating and lighting unit here shown suspended in a room in the same manner as a conventional chandelier results in the radiant heat energy being distributed downward from. the reflector surface located immediately above the heating element and the energy directly radiated from the heating element also is turned downward.
It is to be observed in considering radiant energy as it is herein proposed to employ it, that the said energy does not materially heat air through which it passes and is substantially independent of air currents, room ventilation, etc., but that the radiant rays upon striking an object as a person, a chair or the floor of the room, is thereupon transformed into what we know as heat energy and thus the sensation of warmth is at once produced in the desired position in the room without in any way contaminating the atmosphere or interfering with the ventilation thereof. V
In a structure as above described I prefer to employ a luminous type of heating element at and a copper surfaced reflector 2 which adds greatly to the beauty and the effect of warmth.
I claim:
1. A reflector for radiant energy in combination with a heating unit and a plurality of lighting units, said units positioned inside and outside of said reflector respective ly, said heat element being located substantially about the focus and said light units positioned symmetrically about the periphcry of the reflector and suspension means for said reflector and a passage way there through and a secondary reflecting surface spaced in front of said reflector and adapted to deflect a portion of the heat rays reflected from the first reflector.
2. A reflector for radiant energy in combination with a heating unit and a plurality of lighting units, said units positioned inside and outside of said reflector respectively, said heat element being located substantially about the focus and said light units positioned symmetrically about the periphery of the reflector and suspension means for said reflector and a passage way therethrough and a secondary reflecting surface spaced in front of said reflector and adapted to deflect a portion of the heat rays reflected from the first reflector, and supporting means for said heat unit independent of the reflector.
