13 claims. (c1. 24o-7s) This invention relates to lighting nxtures in general. and more especially to lighting fixtures including means' for producing indirect light rays.

Among the objects of the present invention, it f is aimed to provide an 'improved lighting fixturewhich will not only serve to house the main source of light for a room or the like but will in addition cooperate with the source of light to produce a decorative ornament.

l0 Specifically it is an object of the present in-k vention to provide an improved lighting fixture which will not only serve to house a source of light for a given area or space but also cooperate with the source of light to illuminate the outer decorative face of the light fixture to constitute an illuminated decorative ornament.

It is still another object of the present invention to provide improved connecting devices for connectingthe shells and rims of lighting fixtures made according to the present invention to a support, such as a socket cover or the like.

It is still another object of the present invention toprovide an improved lighting fixture including a decorative ornament and a concealed edge of the hickey 2 and the disc -III disposedv at source of light for illuminating such ornament.

These and other features,capabilitiesv andadvantages of the invention will appear from the subjoined detail description of specific embodiments thereof illustrated in the accompanying drawings inwhich Figure 1 is a side elevation of a lighting fixture made according to one embodiment of the present p invention partly in section;

Fig. 111s a side elevation of a. sixth embodiment of the present invention; and

Fig. 12 is a section on the line I2,I2 of Fig. 11.

Inl the embodiment illustrated in Figs. 1 to 5 inclusive, the embodiment of the lighting xture shown is associated with a ceiling I through which extends the swivel hickey 2 connected to anoutlet box or the like. To the lower end of the hickey 2, there is connected a conduit 3 which is connected at its lower end to vthe lamp socket 4.

In the lamp socket 4l in the present instance,

' there is shown secured a lamp 5 which in the present instance is7 illustrative of the two hundred.l watt lamps extensively used.

vTo cov er the hickey 2, conduit 3, lamp socket 4 and neck of the lamp 5 in the present instance, there is provided a covering having the canopy 6 consisting of the outwardly flaring hollow base portion 1, the upper outer edgeof which engages the face of the ceiling I and from the inner lower end of which there extends the thimble portion 8 through which extends the conduit 9. The length of the conduit 9 is preferably predetermined to correspond to the distance between the lower the upper end of the socket 4 and in whichcase the socket 4 supports the disc I0 and the disc I0 in turn supports the, conduit 9 in position on the n conduit 3. Y i

The canopy 6 in turn is positioned against the ceiling I by the ring IIy mounted on the conduit 9 due to the set screw `I2 extending through the lring Il and frictionallypressed against'theconduit 9. From the conduit 9-downwardly around the disc I0, socket 4 and neck I3 of vthe llamp 6, `there extends the .socket cover I4, the lower end of which is preferably wider than the upper end as indicated ',withan inwardly extending ange I5 at the upper end engaging the outer .face of the conduit Sand anA inwardly extendingange I6 at the lower end. The lower end of the cover I4 is preferably provided with threefsmall slots I1 which are c ut through the ange I8 and up into the outer wall of the cover llas shown in Fig. 1.

The main portion of the present invention will f vnow be described. It consists essentially of the shell I8 having a plurality of `beads or annular steps', fourbeing shown inthe present instance to wit, I9, 20, 2l and 22.` These steps I9 to 22 inclusive are preferably formed as shown in an inwardly curved surface of the shell |8. The lower end of the shell I8 in the present instance terminates in a helmet shaped inverted dome portion 23.

Along the upper outer edge of the shell I 8, therev is mounted an annular rim 24 which is shown as provided v'ith an upper wide inwardly extending flange 25 and a lower narrow inwardly extending flange 26, the flange 25 preferably ex- 5 tending above and inwardly of the outer edge of the shell I8 and the end of the flange 26 preferably terminating below and outwardly of the outer edge of the shell I3. The rim 24 and shell I8 are preferably connected to the socket cover I4. In 10 the present instance they are connected by three sets of connecting devices 21 and ball chains 28. Each connecting device consists essentially of a block 29 composed of a translucent plastic material which is preferably provided with an upper face 38 conforming to the inner face of the flange 25, an outer face 3| conforming to the intervening portion 32 of the rim 24 and a lower face 33 conforming to the inner face of the flange 26, the shoulder 34 preferably being disposed in alinement with the inner edge of the flange 26.

Each of the blocks 29 in addition is provided with a slot 35 extending from its inner face 38 in an upwardly inclined direction and conforming in thickness and shapeto the outer end portion 31 of the shell I8. The block 29 is also preferably provided with a recess 38 extending along a portion of the outer end of the block 29 and the full width of the upper portion of the block 29, see Fig. 5, to receive the metal clip 39 having an outer portion 48, a main shank portion 4I and a front downwardly extending portion 42 provided with a recess 43. The finger 42 is preferably inclined to form a right angle or less with the line of pull of the ball chain 28.

A ball chain 28 as shown in Fig. 1 is connected to the finger 42 and lower edge of the cover I4 in the well known manner by having it pressed into the recess 43 and recess I1 as shown.

The upper flange of the rim 24, see particularly'Figs. 2 and 3 is preferably provided with three

recesses

44, 45 and 46 conforming in Width to the width of the shank portions 4I of the metallic clips 39. In order to connect the connecting devices 21 and ball chains 28 in place, the ball chains are first connected to the connecting devices 21 and to the lower end of the socket cover I4, then the rim 24 is slipped up adjacent the cover- I4 and then the outer edge portion 31 of the shell I8 inserted into the recesses 35 of the blocks 29 grouped together as shown in Fig. 3. The annular rim 24 is thereupon pulled down over the blocks29 and the edge of the shell I8 and thereupon the blocks 29 separated until each register with one of the

recesses

44, 45 and 46.

'Ihe canopy 6, ring II, conduit 9, cover I4, rim 24 and shell I8 may be of any suitable decorative substance, such for instance as aluminum, it of course being obvious that the canopyi, cover' I4, rim 24 and shell I8 may consist of spun or drawn aluminum.

Preferably the inner upwardly extending face of the shell I8 is polished to form or provided with a reflecting surface and the inner faces of the rim 24 similarly polished to form or otherwise provided with a reflecting face for vthe purpose now to be described. 'I'he light rays from the lamp 5 may of course be freely directed upwardly against the ceiling I to -produce indirect light rays. In addition, the light rays, see for instance the dash and dot lines of Fig. 1, pass from the lamp 5 first to the inner face of the flange 25, then to the inner face of the intermediate portion 32 and from there onto the outer face of the shell I8. Obviously the angle of the inner face of the flange 25 and the inner face of the intermediate portion 32 relative to the lamp 5 will depend upon the curvature or inclination of the outer face of theshell I8 in order to produce the desired lighting eiect on the outer face of the shell I8. l

It is oi' course obvious that the bulbous portion 41 of the lamp 5 may besilvered or provided with a metal cap. such as the cap 48 having an inner reflecting surface in the interest of indirect lighting without departing from the spirit of the invention.

In the embodiment shown in Fig. 6, the lower end of the socket covering 49 corresponding to the socket covering I4 in Fig. 1 is connected to a fixture portion having a plurality of shell members and rim portions. When two shell members, such as the shells 58 and 5I are used, the upper shell consists of an annular memberhaving a rim 52 at its lower end to cooperate with the shell 58 and a separate rim 53 is provided to cooperate with the shell 5I. 'I'he shell 58 in this embodiment is provided with one step formation 64 dividing the shell 58 into an upper annular area 55 and a lower inverted helmet shaped area 56.

In this embodiment too, there are preferably provided three ball chains 51 similar to the ball chains 28 of the embodiment illustrated in Fig. l connected to the lower end of the socket cover 49 by means of recesses as shown in Fig. l and connected to the projections or fingers 58 of the connecting devices 59, similar tothe connecting devicesA 21, secured to the outer upper edge of the shell 58 and to the rim 52 similar to the rim discussed in the embodiment illustrated in Fig. l.

The rim 53 on the other hand is provided with three blocks 68 having upper and outer faces conforming to the inner faces of the rim 53 and slots 6I conforming in thickness and shape to the upper outer edge portion 62 of the shell 5I.

To assemble the several parts of this fixture, the rim 53 is iirst slipped in place adjacent the cover 49 either before or after the ball chains 51 are connected to the socket cover 49 and their connecting devices 59, then the blocks 68 slipped in place on the outer edge portion '62 ofthe shell 5I, then the rim 53 slipped down over the blocks 68 and then the blocks 68 equally spaced from one another. be secured to the shell 5I before slipping it up adjacent the socket cover 49. Thereupon the connecting devices 59 are grouped together and slipped on the outer edge portion 63 of the shell 58 and then the rim portion 52 slipped over the connecting devices 59 and thereupon the connecting devices 59 equally spaced from one another as explained with regard to assembling the parts illustrated in Fig. l.

With this-embodiment, it will of course appear that the angle of the inner faces of the rims 53 and 52 relative to thelight rays coming from the lamp 64 will depend upon the curvature and inclination of the outer faces of the shells 5I and 58 to produce the desired lighting eifect.

In the embodiment illustrated in Fig. '1, the lamp 65 is secured in a lamp socket disposed adjacent to the ceiling 68. 'I'he socket cover 41 is secured in place in any well known manner. To

On the other hand, the rim 53 may the lower end thereof, there. are connected thel l ball chains 68 which are associated with the connecting devices 69 similar to the connecting devices 21 shown in Fig. l, which are mounted in has provided at its lower end a chain connection 12 to which there is in the present instance attacheda decorative ball 13 composed v,for instance oi' glass or other light reecting substance.

Preferably in the present instance, there extends froxn vthe ceiling 68 an annular shell 14 spaced from the outer edge of the rim 10 to cooperate with the rim 10 and shell 1| to form a ceiling fixture.

In'the present instance, some of the light rays from the lamp 85 will of course be directed upwardly against the ceiling inside the shell 14 and also be directed against the inner face of the shell 14 preferably formed'into a reflecting sur- 15 face and other light rays from the lamp 65 will be directed against the inner face of the rim 10 to be reected against the outer face or decorative surface on the outside of the shell 1| and also onto the glass ball 13.

In the embodiment illustrated in Figs. 8 and 9, the suspended shell 15 conforms to an inverted six-faced pyramid with alternate triangular faces 18, 11 and 18 provided with an ornamental finish and the remaining triangular faces 19, 80 and 8| 25 either provided with an ornamental finish or plain as indicated in Fig. 9. The upper end portions 82 of the

panels

16, 11

and 18 have each attached thereto a reflecting rim 83 similar tothe reflecting rim 24 of the em- 30 bodiment illustrated in the embodiment of Fig. l. These reflecting rims 83 may be separate straight pieces as indicated in Fig. 9, each separately connected to the socket cover 84 by connecting means including ball chains 85 and connecting

devices

81 and 88 near its ends to receive the fingers .89 of the connecting devices 86, which fingers 89 are similar to the fingers i2 of the embodiment illustrated in Fig. 1 and associated with blocks 90 similar to the blocks 29 of the embodiment iliustrated in Fig. 1.

With this embodiment, it will of course appear that alternate faces will be illuminated in the interest of the ultimate decorative effect.

In' the embodiment illustrated in Fig. 10, the invention is shown associated with a floor lamp in which the upright 9| has formed at its upper end a lamp socket to receive the lamp 92 with its bulbous end facing upwardly and the socket oftheflamp provided with a cover 93 which is provided with slots at its upper end to receive the ends of the ball chains 94 connected to the fingers 95 of blocks 96 secured in a reflecting rim 91 formed at the lower edge of the shell 98, the shell 98 in the present instance being coni-l l cal with its Wide end at the' bottom.

The outer face. of the shell 98 in the presen `instance may beformed to produce a decorative effect or provided with a decorative surface as shown. Some of the light rays, from the lamp 92 will of course be directed against' the inner face of the shell 98 which may be provided with a reecting surface to be directed downwardly e v and other light rays be directed against the inner 3" face of the rim-91 'which is provided with a refieeting surface, the angles of which rim relative to the lamp are such that the light rays will in turn be deiiected onto the outer'face of the shell" 98 or thegdecorative effect on the shell 98.

70 The blocks 96 of the connecting devices in the present instance are invertedV as compared tor the embodiments heretofore described and th'e shape of the same consequently slightly changed. 75 In other respects the connecting

devices

96 and 88. Each rim 83 is provided with two notchesl ball chains 94 are practically the same as those used with the embodiment illustrated in Fig. 1.

In the embodiment illustrated in Figs. 1 1 and 12, there is shown a Wall bracket 99 to which is connected a lamp and a shell |0| to, intercept the direct rays from the lamp |00. The outer face of the shell |0| is preferably provided with an ornamental effect either due-to the configuration of the shell itself or to the ornamental matter secured thereto. Disposed along the vertical edges of the shell there are provided the vertically extending rims |02 and |03 having refleeting faces to receive some of the light rays from the lamp |00 and reflect them onto the adjacent outer faces of the shell |0I.

It is of course obvious that the shell, as for instance the shell i8 of the embodiment illustrated'in Fig. 1 may itself be constructed to present an outer ornamental configuration or else the outer face or faces of the shell i8, see for instance the outer faces of the shells 50 and 5| of the embodiment illustrated in Fig. 6 provided with ornamental devices to produce an outer ornamental effect, see also the shells of the embodiments illustrated in Figs. 7, 8, 10, and 1l.

It is of course obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
