April 1934- I s. R. NAYSMITH v 1,953,816

INCLOSED INDIRECT LIGHTING FIXTURE Filed Oct. 23, 1951 mummw ,XNVENTOR ATTORN EY Patented Apr. 3, 1 934 UNITED STATES- 1,953,816 INCLOSED INDIRECT LIGHTING FIXTURE Shirley R. Naysmith, Meriden, Conn., assignor to The Miller Company, Meriden, Conn., a corporation of Connecticut Application October 23, 1931, Serial No. 570,525

I w 24 Claims.

The-present invention relates to inclosed indi- "lect lighting fixtnres and is more especially designed to provide such fixtures capable of efficiently employing large lamp bulbs. It is designed to give an extensive, upward direction of light with or without adim-ly'illuminated lower translucent bowl. It is also so designed that the lamp bulb is screened from ordinary angles of vision so as not to produce glare.

- The present invention-contemplates an inclosed 7 tachable from underneath to give access to the lamp bulb for bulb renewal.

In order to completely enclose the unit, the glass cover member is designed so that its outer edge engages one of the lower members.

The accompanying drawing shows, for pure poses of illustrating the present invention, several embodiments in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting 539 the same. In the drawing:

Fig. 1 is an elevational view with parts in section showing one form of an enclosed lighting unit designed for totally indirect lighting;

Fig. 2 is a fragmentary sectional view with parts omitted and taken on the line 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 1 showing a modi- :fied form of construction for obtaining a small :amount of downwardly diffused light;

Fig. 4 is a sectional view on the line 44 of Fig. 4B 3 on an enlarged scale;

Fig. 5 is a sectional view showing a further modified form of construction; and

Fig. 6 is a fragmentary detail. I I .A pendant lamp socket 10 supports a lamp bulb 11 as usual. The lamp socket is inclosed in a socket cover 12 which supports three screws indicated at 13. These screws support a ring-like member 14 carried inside the socket cover and large enough to admit the neck of the lamp bulb. This ring-like member may be a sheet metal stamping or spinning and is'drawn outwardly at its lower edge as indicated at 15 so as to receive and support the translucent glass cover plate 16 of a comparatively largediameter and having its lower edge extending downwardly as indicated at 17.

The ring 14 also carries two sheet metal straps l8 and 19 which may be riveted to it as indicated at 20. The lower ends of these frame members so 18 and 19 carry links 21 and 22 and these links support a lJ-shaped strap 23 twisted as indicated. This strap is somewhat larger than the diameter of the lamp bulb 11 so that the frame is able to receive the largest size lamp bulb for which the unit is designed. The strap 23 is secured to a turning 24 by screws indicated at 25. This turning is threaded as indicated at 26 and carries a downwardly extending stem 27 which may be in the form of a nipple. The links 21 and 22 permit swinging the strip 23 and stem to one side as indicated in dot and dash lines in Fig. 2 so that the bulb may be removed or inserted.

The sheet metal reflector 30 has a central opening to receive the upper end of the turning 24 and is clamped against the strap 23 by a threaded ring 31. This reflector has a central substantially spherical portion 32 and an outer peripheral portion 33 which is of shallow dished shape as indicated. The outer edge 34 of the reflector is adjacent the lower edge 1'? of the glass cover plate.

It will be seen that the reflector and cover plate afford widespread upward illumination, the paths of the rays being as indicated in the light lines in the drawing.

The shape given the reflector 30 is not ornamental and in order to provide an ornamental unit a lower mask or cover member 35 is furnished. This cover member may be made of 7 sheet metal and is held in place by a knob 36 threaded on the lower end of the stem 27. The lower cover member extends upwardly and may touch the outer edge of the reflector so as to assist in aligning it. It may also carry a felt ring 3'7 which acts as a gasket between the lower cover member and the upper glass cover, the outer edge 38 of the mask extends above the glass cover 17 so as to screen this glass against vision at ordinary angles.

In the form shown in Figs. 3 and 4, the upper glass cover 16 and the upper parts of the frame 18 and 19 are the same. Here the links 21 and 22 support a U-shaped strap 40 which in turn carries a depending nipple or stem 41. The nipple 105 and strap are secured together by a pin 42.

A sleeve 43 is slidably received on the lower part of the nipple 41. This sleeve permanently carries a small reflector stamping 44 and is threaded at its lowerend'as indicated at 45 tore- 1 10,

ceive a locking ring 46. This locking ring is adapted to clamp an ornamental stamping 47 against the bottom of a diffusing glass bowl 48 which forms the lower ornamental part of the lighting unit. This bowl is apertured as indicated at l9 to receive the sleeve and the bowl and fittings may be removably supported on the stem ll by a knob indicated at 50.

The upper edge 51 of the diffusing glass bowl 48 supports a sheet metal stamping or spinning 52. This sheet metal part has a central spherical portion 53 and an outer shallow dished reflecting portion 54 similar to the parts 32 and 33 shown in Fig. 1. The stamping extends upwardly and outwardly from the outer edge of the glass bowl and receives the lower edge 17 of the glass cover member, a felt gasket 55 being interposed. The outer portion 56 of the stamping or spinning 52 masks the glass cover 16.

The reflector stamping has a central opening 57 to permit a small amount of light to pass downwardly where it strikes the reflector 44 and is scattered thereby to illuminate the lower diffusing bowl 48.

Figs. 5 and 5 show the frame members 18 and 19 in the form of resilient lengths of wire secured to the ring 14. The lower ends of these wire frame members are provided with collars 60 which are adapted to pass through large holes 61 in a reflector stamping 30, similar to the corresponding part in Fig. l. The wires spring outwardly and enter the small parts 62 of these slots and support the stamping 30' in place. When the frame members 18' and 19' are squeezed toward one another slightly, one can release the stamping from either one or both of the frame members. If it is removed from only one frame member, it may hang down as indicated in the dotted line position so as to give access to the lamp bulb. Its upper edge passes inside the cover plate 16 as indicated. The center of the reflector stamping 39 carries a depending stem 63 which may support the lower cover member.

At the left side of the figure the diffusing bowl 48 is indicated in full lines. It supports a spinning or stamping 52', 56' having the shape indicated. This stamping may extend in and engage the stamping 30' to align it. The stamping 30 is perforated as indicated at 64 to permit light to pass downwardly for illuminating the diffusing bowl 48.

At the right hand side of Fig. 5, the sheet metal mask 35 is indicated in dot and dash lines.

It is obvious that the invention may be embodied in many forms and constructions, and I wish it to be understood that the particular forms 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.
