DOANE, 0F MERIDEN, CONNECTICUT, ASSIGNOR TO THE MILLER COMPANY, OF MERIDEN, CONNECTICUT, A CORPORATION OF CONNECTICUT LIGHTING APPLIANCE Application filed July 7, 1928.

The present invention relates to lighting appliances and is more particularly directed to lighting appliances such as chandeliers and table lamps having an opaque shade associated with deflecting and reflecting devices so arranged about the light source that the outside surfaces of these parts are illuminated.

According to the present invention an opaque metal shade or deflector is associated with suitable devices whereby the outside of the metal shade is illuminated by a light reflected from a concealed surface preferably carried by an opaque shade cover. Color changing media may be employed, preferably on this concealed surface so that the redirected light is colored, whereby the outside of the metal shade appears colored, according to the arrangement of colors emploved. Accordingly these light reflecting devices although opaque appear as a source of light, colored, if desired. They are lighted at a low intensity so they do not product dark spots in the range of vision.

The present invention also contemplates the provision of lighting appliances of this nature wherein substantially all of the light emitted by the light source is under the control of reflecting surfaces so that the light can be directed to the desired direction, colored or not by reflecting surfaces, as desired.

A further object of the invention is to provide a chandelier or table lamp embodying the features above enumerated and wherein the parts may be readily taken apart and separated for cleaning and replacing lamps.

Another object of the invention is to provide such lighting apparatus with an illuminated glass knob which preferably holds certain parts of the apparatus together.

A further object of the invention is to provide a series of chandeliers, table lamps and the like having the various features above referred to and made out of a comparatively small number of different parts. These parts are designed so that they can be expeditiously assembled into various desired forms.

Serial No. 290,897.

The accompanying drawings show, for purposes of illustrating the present invention, several of the many possible embodiments in which the present invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figure 1 is a diagrammatic side elevational view, with parts in section, illustrating one form of chandelier more especially designed for smaller lamp bulbs such as 150 Wa t;

Figure 2 is a view similar to Figure 1 showing a table lamp employing many of the parts shown in Figure 1;

Figure 3 is a View similar to Figure l illustrating a form of ceiling fixture suitable for using somewhat larger lamps than the form shown in Figure 1; but employing many identical parts;

Figure 4 is an enlarged sectional view through the upper part of the table lamp of Figure 2 or through the lower part of chandelier of Figure 1;

Figures 5a and 5b are sectional views with parts in elevation, of a slightly modified form of ceiling fixture suitable for using larger lamps;

Figures 6a and 6b are sectional views with parts in elevation, of a table lamp more especially arranged for small lamps; and

Figure 7 is a sectional view through a form of glass knob taken on the line 77 of Figure 4.

The chandelier shown in Figures 1, 3, 5a employs asheet metal canopy 10 adapted to be supported by screws 11 fastened to across bar 12. A conical socket cover orstem 13 is carried below the canopy. These parts may be fastened together by a nipple 1%,nuts 15 and 16,lock washer 17 and abreak ring 18. As more clearly indicated in Figures 5a and 5b, the nipple supports a downwardly opening lamp socket 20. Thesocket cover 13 is preferably long and slightly tapered and adapted to receive theneck 21 of the lamp bulb 22. The table lamp of Figure 2 is provided with abase 25, standard 26,'which is adapted to support asocket cover 13 which may be identical with that used in the Cl1t11 delier.

The remaining structure for making up a chandelier, as shown in Figure 1, or a table lamp as shown in Figures 2 and 4, is identical, the parts being assembled according to the use to which the unit is to be put. For convenience of description, the enlarged ligure of the table lamp of Figure 4, will be employed.

A number of slide rods orstraps 30 are riveted or otherwise secured to themouth 31 of thesocket cover 13. These side rods or straps support aring 32 which is somewhat larger than the lamp bulb. This ring is preferably permanently riveted to thestraps 30. A metal reflector orshade 33 of desired shape carries a number of interiorly disposed fingers 34 riveted to it, as indicated at 35. These fingers have outwardly struckprongs 36 and 37 adapted to receive the ring These fingers 34"are of resilient material so that they can be easily caught onto or released from the ring. The two prongs 36 and 37 engage thering 32 both above and below, so that the shade is held in place whichever side up the structure is mounted.

Theshade 33 is provided with a number ofwindows 38 adapted to be covered by a small outermetal reflecting cover 39. The

1Wtwometal,stampings ,33Van d 39 are held together by a glass knob 40 having lugs 41 adapted to pass throughnotches 42 in these 5 metal parts. The inner surface of themetal stamping 39 is adapted to be covered by colored material as indicated by the stippling 43. This colored material may be uniform or splotched or daubed on in any desired 40. manner so as to obtain varied colors. This colored material is placed opposite thewindows 38 so that the light passing through these windows will be reflected and colored.

As shown in Figure 1, some of the light 45 from the light source is reflected upwardly from the inside of thedeflecting shade 33 as indicated by the rays a. This light may be colored or not as desired by applying suitable inside surface of theshade 33. Some .of the light is directly emitted as indicated by the ray b. A small portion of the light, however, passes through thewindows 38 where it is reflected in colors by the coloring material 43 so that the colored beams are directed onto the outside of thereflector 33 which receives the light as indicated by the ray 0. This portion of theshade 33 is concave to the incident light so that the light is scattering in a pleasing manner.

60.. The same letters are employed in Figure 2 for indicating the similar rays of light emitted from the table lamp. In each case some of the light also passes into the glass knob 40' thereby illuminating this knob and as making it glow as indicated by the rays marked d. Some light from the knob falls on the outside of thecover 39 so it is illuminated.

In the form of construction illustrated in Figure 3, theshade 33,cover plate 39, knob a0 and spring catches 34 andring 32 may be the same as has been described and shown in detail in Figure 4L. Thering 32, however, is supported by a longer strap as indicated at 30 to place these parts in the proper position relative to the center of the light source, A supplementary reflector 11 is supported on thestraps 30 above themain reflector 33. This supplementary reflector all acts on some of the light as indicated by the ray 0 to reflect it in a horizontal direction.

In the form of construction shown in Figure 5b, which is also adapted for larger lamps, thelonger straps 30 are employed for supporting aring 32 similar to the ring employ d in the' construction shown in Figures 1 to 4, inclusive. In this case, however, thelower reflector 50 is smaller thanreflector 33 and an upper reflector 51 is employed above this lower reflector. Thelower reflector 50 is substantially the same construction as thereflector 33 and is provided with thewindows 38,cover 39,glass knob 10 and color reflecting surface 43 as 9 above described in detail. The reflector 51 may beilluminated on the outside by light reflected from thelower reflector 50. This light may be colored or not if desired by coloring the reflecting surface.

The form of construction shown in F ig ures 6a and 6?) is more particularly adapted for a small table lamp. This lamp employs a cast iron base 60, a sheetmetal cover plate 61, abreak 62 andtubular socket cover 63. These parts are fastened tgether by a length of pipe 64-,nuts 65 and 66 as indicated in Figure 60.. The upper end of the pipe 64: supports thelamp socket 67 in the customary manner. This lamp socket is adapted to support anupright bulb 68. Theshade 69,cover plate 70 andglass knob 71 may be substantially the same that shown and described in detail in Figure 1 except that these parts are of smaller size. They act on the light in the same manner as heretofore described.

Instead of supporting these reflector devices from the socket cover, they are, as shown in Figure (it, supported by a shade support 72 having spring fingers 73 which engage the lamp bulb. This shade holder may be of the type shown in Patent No. 1,682,918, September 4, 1928, and permanently secured to the upper part of the shade 60.

It will be noted from the foregoing that the various types of lighting apparatus above described are such that the outside of the metal reflectors are illuminated by a soft flecting surfaces so that it may be directed in the desired manner to produce either ceiling illumination or table illumination. The apparatus may be readily taken apart for relamping and for cleaning. Inasmuch as the parts are all made of metal, except the glass knob, they are strong and substantial, capable of accurate manufacture in an inexpenslve manner so that a satisfactory lighting apparatus may be produced by economi- "cal manufacturing methods.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims, and I wish it to be understood that the particular forms l shown are but a few of the many forms.

Various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
