Patented June 24, 1930 'UNETED stares PATENT QFFEQE CAREY C. HOEL, OF COLUMBUS, OHIO, ASSEGNOR T0 JEANNETTE SHADE AND NOVELTY COMPANY, OF JEANNETTE, PENNSYLVANIA LIGHTING 7 Application filed April 27,

This invention relates to electrical lighting fixtures, and particularly to a globe for surrounding the lamp and means for sup porting the globe in close contact with the ceiling or wall to which it is attached. One of the objects of the invention is the provision of a simple and efiicient structure which can be economically manufactured and readily installed, and which will properly diffuse the light from practically its entire visible area and will hide substantially all of the metal support fittings. A further object is to provide a structure which is sealed to prevent the entrance of dirt or insects so that the structure can be easily cleaned and frequent cleaning will be unnecessary. A still further object is to provide for substantially uniform difiusion from the whole area of the structure, and still further objects of the in vention and various novel features of construction will be apparent from the following specification when read with the accompanying drawings, in which:

Fig. 1 is a view in side elevation of a lighting fixture embodying the invention;

Fig. 2 is a fragmentary view in vertical section of the structure shown in Fig. 1; and,

Fig. 3 is a fragmentary top plan view of the structure shown in Figs. 1 and 2, showing details of the supporting members.

The invention relates to lighting fixtures of the type in which an incandescent electric lamp is surrounded by a bowl or shade of opalescent glass, or similar material, which radiates the light from a relatively large area. In order to reduce to a minimum the exposed metal parts, which are liable to tarnish and are difiicult to clean, to materially increase the radiating area, and to render the entrance of dirt or insects impossible, the bowl is formed in one piece with a glass canopy portion which surrounds the supporting means, so that the integral luminous combined unitextends substantially to the ceiling line.

As shown in. the drawings, the shade has a bowl portion 11, of suitable design, formed integrally with a canopy portion 12, which narrows gradually to a neck 13 where it joins the downwardly sloping upper portion 14: of

the bowl 11. An annular flange 15 is formed at the top of the canopy portion12, and adjacent such fiange the canopy portion pref erably extends in a plane to form a flat circumferential shoulder 16 for cooperation with the supporting means, as will presently appear. t is preferable that. the walls of the canopy portion 12 and the portion 14 be slightly thicker than those of bowl .portion 11, as indicated in Fig. 2.

A support strap 17 is adapted to be supported upon the wall or ceiling, either by screws passing through slots 18 in the strap or by a pipe or other member cooperating with a central hole 19 in the strap, so that the fixture may be secured direct-1y to the ceiling or to the usual outlet box. l/Vhile the device is herein shown as attached to a ceiling, it will be understood that it may be attached to a side wall or similar surface, and the word ceiling is used to include a wall or such other fiat surfaces.

A reflector 20 is removably secured to the strap 17 by nuts 21 which engage threaded studs 22, carried by the strap 17 and extending downwardly through openings in the reflector. The studs 22 may be threaded through the strap 17 or may be secured thereto in any other desired manner. The depending portion of the reflector is roughly conical, the reflecting surface23 being concaved and substantially parabolic, and at its lower edge it is provided with an inturned flange 2 which supports the lamp socket. As shown in Fig. 2, the lamp socketis preferably of the type formed of a base 25 and a cap 26 which screw together, a rubber washer 27 and the flange 24 being clamped between the parts so that the socket is rigidly and tightly supported and danger of breakage is avoided. The wires 28 which lead into the socket base 25 are to be connected to the supply wires and may extend along the side of the strap 17.

Adj acent its peripheral edge, therefiector 20 is flattened to form. a circumferential shoulder 29 and, adjacent such shoulder, it has an annular cylindrical neck 30 which terminates in a fiat laterally eX- tending flange 31, rolled over at 32 to form V ahead which is spaced slightly from the neck tight engagement with the ceiling, the lamp may be emplaced and the combined bowl and canopy unit may be mounted to enclose the lamp, being secured in place by nuts 34 which engage the shoulder 16 and thread onto the studs The flange 15 of the canopy portion fits closely about the neck 30 of the reflector, its upper edge being received between the neck 30 and the bead 32, and if desired, a suitable washer or gasket 85 may be used between the flange 15 and the flat flange 31;.

If any difliculty is experienced in so mounting the support strap that the reflector will fit properly against the ceiling, the lamp socket may be removed,,so that with the reflector secured to the strap by nuts 21, access may be had to the strap supporting screws through the lamp socket opening in the reflector. It will be apparent that the reflector is supported by the strap 17, and in turn supports the lamp socket and the bowl and canopy unit. Since the reflector fits tightly against the ceiling, and forms circumferentially continuous engagement with both the lamp socket and the integral canopy and bowl unit, it will be evident that the space in which the lamp is placed is effectively sealed against the entrance of dust or insects.

When the fixture is in use no metal parts are visible except the nuts 34; and the bead tween said neck and said bead, and means for ing a shoulder terminating in a rearwardlyextending annulus, and means for detachably securing said shade to the reflector with its shoulder and annulus completely covering respectively the shoulder and annulus of the reflector.

In testimony whereof I aflix my signature.

32. Because of the translucent nature of the V bowl and canopy unit light will be radiated from the whole unit, even from the flange 15, and the rounded bead 32 is practically invisible. A considerable portion of the light is reflected by the reflector 20 to the a canopy portion 12, andthe brilliance will de crease gradually as the ceiling line is approached. There are also no surfaces upon which dust could settle except the steeply sloping surface 14C which is usually not Visible and which can be readily cleaned.

While one specific embodiment of the invention has been described, it will be understoodthat many changes may be made in the details of construction within the scope of the invention which is defined by the following claims. What is claimed is:

1. In a lighting fixture, a reflector having a cylindrical neck and a flat peripheral flange terminating in an outwardly rolled bead spaced from said neck, means for supporting said reflector with said flange in engagement with a ceiling or wall lamp supporting means carried by said reflector, a translucent shade surrounding said reflector and engaging said. flange with the edge of the shade be-
