Description

Oct. 11, 1932. P. M. HOTCHKIN 1,831,594
ILLUMINATING DEVICE Filed May 15. 1930 Patented @et. 11, 1932 r aria PAULINE. EOTOHKIN, OF CHICAGO, ELLINOIS, ASSIGNORTO CURTIS LIGHTING, INCL, OF CHICAGO, ILLINOIS, A CORPCRATION OF ILLINOIS rnnuiainnrmo Dnvrcn Application filed May 13,
My present invention relates to an illuminating device of the type known as directindirect in which indirect illumination is provided by an inverted reflector element that throws the light upwardly from a light source toward the ceiling, and the direct or difiused illumination is secured by means of a shade which encloses or surrounds the re-' flector and is illuminated to avoid the appearance of a dark object or shadow at the location which the upwardly directed light rays originate.
In the present structure I have provided the portion inside the shade in the form or" a unitary structure which is adapted to act both as the reflector for the indirect illumination and as atransmitter or difiuser for the rays that are directed upon the shade which is more or less translucent.
My present invention has been devised with numerous objects in view among which may be mentioned the provision of an illuminating device that is novel in construction, easy'to manipulate, dependable in operation, and capable of effecting artistic results.
I prefer to carry out my invention and to accomplish the objects thereof in substantiall the manner hereinafter described as more particularly pointed out in the claim, reference being made to the accompanying drawing that forms a part of this specification.
In the drawing Figure 1 is a vertical side elevation of a lighting fixture of the fioor or stand type made in accordance with my invention, the parts at the upper portion thereof being broken away and in section.
Figure 2 is a view similar to the upper portion of Figure 1, partly in section, and showing a modified structure.
Figure 3 is a View similar to the preceding figures showing the upper portion of another modified type of fixture made in accordance with my invention.
The drawing is more or less schematic for the purpose of illustrating typical forms in which my'invention may be made, and in said drawing similar reference characters have been employed to. designate like parts where- 1930. Serial 1\T0.452,078.
ever they appear throughout the different views.
Referring more particularly to'Figures 1 and 2, it will be seen I have provided a standard or column 5 that has a suitable base 6 and which terminates in a suitably shaped head or top 7; The head or top 7 is preferably cup-shaped and is provided with a houlder 8 at its upper portion that terminates in an upstanding flange or flare 9. This upper portion of the head provides a seat to receive the exceriorshade'lO of the fixture which is'preierably hollow and made from translucent or light transmitting material and rests at its lower end upon the shoulder 8 within the flange 9 so that the lower portion of the shade is closed.
A suitable lamp socket 11 is mounted within the lower position'of the shade above the head 7 of the column and it is surrounded by a cup-shaped member 12 that is provided upon its upper edge with a seat 13 to receive the light controlling and directing member. An electric light bulb 14 is insertcdin the socket l1 and is surrounded by the light control structure which will be later described. The bulb 14 is preferably of a high wattage and the rays of light therefrom are utilized as the sole or only means for securing the indirect illumination that is reflected upwardly and for the diffused direct illumination which is transmitted to the shade 10 by this control structure.
The light controlling and directing structure has its upper section formed so as to provide an inverted bowlshaped reflector 15 that is surrounded by the shade 10 and is so disposed that the light rays from the bulb striking its mirrored surfaces will be refiected in an upward our-ward direction to the ceiling from which it is returned to the interior of the room. The lower portion of the reflecting section is formed into a restricted opening 16 that surrounds the tapered portion of the bulb but which spaced therefrom a distance sufficient to permit light rays from the bulb to travel downwardly through said opening 16.
Below the opening the light control structure consists of a diffuser 17 which is preferably made from opal-glass or other translucent material which will permitlight rays impinging upon its inner surface to be trans mitted in diffused form through the same, 1 and then be distributed upon the interior surface of the shade As shown in F ig ures land 2 the diffusing section of the light control structure is formed of glass and made integrally with the reflector section, where 10 as, in Figure 3 the diffuser section 18 is in the form'of a separ'atecup-shaped part be low the reflector and surrounding the open-1 ing 16in the lower portion ofthe'latter.
In said Figure 3 the-reflector section is '15 supportedabove the difiuser cup by means of an open frame 19 that extends upwardly from the socket or other portion of the fixtur'e, It is immaterial how the frame is supported. Q 7
20 In Figure 2 I have shown a structure similar to that illustrated in Figure 1 andin addition to securing the inside illumination of the shade 10 I have; alsoprovided brackets or armsQO extending outwardly from the head 7 of the column and have provided sockets-upon the ends thereof in which auxiliary exterior bulbs 21 1'nay be mounted.
y In all of the forms shown it will be noted the shade is open at its top but its bottom portion is closedso asto prevent direct light rays or diffused light rays from passingout of the fixture in a downward direction;
' "What I claim is s .A combined direct and indirect lighting 5 fixture comprising a vertical standard, an
opaque support arranged substantially horizontally at the upper end of said standard,
a translucent shade open at its top and hot 7 tom mounted on the rim of said support to close its bottom opening and prevent passage of light rays therethrongh, an extension pro jecting from said standard into said's'hade, an electric socket on the upper end of saidextension, a light bulb in said socket, a translucent light-diffusing bowl supported from said extension and providing the sole means for transmitting light rays from the bulb to the shade, and an inverted opaque reflector above said bowl and surrounding the bulb and adapted to reflect light rays from the latter upwardly out of the fixture.
Signed at Chicago, in the county of Cook and State] of Illinois, this 30 day of April, 1930.
