direct or semi-indirect lighting fixtures and consists of novel means for carrying the bowl support.

It further consists of other novel features of construction all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results although it is to be understood that I the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and or ganization of these instrumentalities as herein shown and described.

Figure 1 is a sectional view of a support, embodying my invention, with the supporting chains broken away and the socket cluster and lamps in dotted lines. Fig. 2 is a sectional view on line ww, Fig. 1. Fig. 3 is a sectional view on lme y y, Fig. 2. Fig. 4: is partial sectional view and partial elevation, broken away, of a slightly different construction. Fig. 5 1s a detailed section of another manner of connecting the chains to the arms. Fig. 6 is a sectional view on line ra -a, Fig. 5.

Similar numerals of reference indicate corresponding partsin the figures.

' Referring to the drawings, 1 designates the body portion of the support or frame which is here shown in the form of a plate and carried by the body portion are rods 2 which extend downwardly and are connected with a disk or plate 3, these parts forming a suitable strong andrigid structure. At suitable points in the d1sk or plate 3, I provide adjustable bowl clamping members or screws '4, here shown as thumb screws, in threaded engagement with said disk 3, whereby each 'is independently adjustable to provide for inequalities inthe bowl. Each of said clamping members '4: is here shown as provided with a rubber cap or block 5 serving as a resilient engaging means for the bowl. Also carried by the disk 3 is a threaded bowl supporting member or collar 6.

7 designates a threaded guide channel here shown as a tubular sleeve which is adapted to pass through an opening in the bowl to have suitable engagement with the threaded member or collar 6 so that a clamping member carried by the sleeve 7 will, in conjunction with the members 4, grasp the bowl to support it. vBy reason of the threaded engagement of the sleeve 7 and the member 6 these parts are adjustable with respect to each other and I preferably form a shoulder 8 on said sleeve adapted to abut the disk 3 to limit the inward movement of the sleeve into the collar 6. In the wall of said tubular member 7 is an opening 9,- or a plurality thereof, suitably located therein adjacent the bottom of the interior of the bowl 10 through which openings the accumulations of dust, dirt, etc., in the bowl may be readily removed through the sleeve 7 without disturbing the connection of the bowl.

ll designates a clamping or yielding washer suitably supported or carried by the threaded sleeve 7 to be located exterior of the bowl 10, and, as shown, I provide an extension flange bowl supporting shelf 12 on said sleeve for this purpose which is provided with a side wall 13 for properly holding the washer in position. The clamping washer 11 may be of any suitable construction and, as here shown, is formed of a ring preferably of rubber serving as a resilient clamping washer and between which and the adjustable bowl clamping members 4 the bowl '10 is held. By means of this construction it will be understood that the adjustable bowl clamping members 4 engage with the inner wall of the bowl and by rea son of their independent adju'stability, provide for any inequalities that may exist in the bowl and the adjustable connection of the threaded sleeve 7 with the'collar 6 provides for the proper gripping action of the clamping 'members initially, in order that the bowl will be properly held without liability to breakage with the clamping washer 11 engaging the outer wall of the bowl around the opening therethrough.

14: designates bars connected with the body 1 and which project at intervals therefrom and are situated within'the bowl 1O but out of contact therewith. In order to connect the bars with the frame I have here shown pins 15 secured to the body 1 each of which is seated in a recess 16 in the inner end of a bar so that when the screws 17 secure the bars to the body 1, these pins will assist in firmly and securely holding the bars and will take up some of the strain thereon.

l8 designates carryingmeans for the fixtures, such as chains, each having one end connected with a bar and the opposite end of each of which is connected to a suitable support from the ceiling, whereby it will be understood that the frame and bowl are supported by the chains which are not directly connected with the bowl.

I may connect rosettes 19 at suitable points around the bowl in line with the ends of the chains 18 in order to give the appearance that the said chains are connected directly with the bowl 10. In order that the bars may be adapted for various sized bowls, I have formed the same adjustable and, as shown, by having an extension member 20 connected with the bars 14 by screws 21, whereby it will be understood that the end thereof to which the chain is connected can be radially adjusted with respect to the body 1.

In Fig. 5 I have shown a different manner of connecting the chains with the bars and in this construction I provide a removable hook 22 carried by the body portion 23 having a recess 24: in its side in which the end of a bar 14 is seated and to which it is secured by a screw 25, it being noted that the end of the hook 22 when in position is situated over and adjacent the top 'of the bar 14 so that displacement of the chain is prevented. Removably connected with each body portion 23 is an arm 26 which projects upwardly and outwardly beyond the upper edge of the bowl 10. 27 designates a band which extends around the bowl and is secured to the arms 26 and has a portion which extends downwardly below the outer upper edge of the bowl but out of contact therewith by which means the edge of the bowl is concealed and suitable ornamentation is provided which while giving the appearance of being directly connected to or carried by the bowl is disconnected therefrom.-

In the construction shown in Fig. 1, I carry the frame from a central supporting means, such as a chain 28, in suitable connection with the body 1 and in this instance I provide rigid ornamental devices 29, such as festoons, one end of each of which is connected with an arm 1 1 and which devices extend upwardly above the top edge of the bowl 10 and have their other end suitably supported, as by being connected with ornamentation 30 carried by the chain 28 by which means it will be seen that without securing the festoons to the bowl 10, I can locate the same to give the appearance thereof, since it is a disadvantage to connect the ,festoons directly with the bowls as such connection is liable to crack or break the bowl. If desired at points in line with the end of the festoons 29 I may support an ornamentation 31 on the bowl to give the appearance of a continuation of the festoon 29.

lVhen the structure shown in Fig. 1 is employed the conductors (not shown) for the electricity are brought down one of the supporting chains 18 and pass through a rubber bushing 32 carried by the body 1 and through a metal coupling or hickey 33 to the interior of a socket cluster 34 to be suitably located to provide contact with the lamps 35. The socket and lamps are shown in dotted lines and the socket cluster is carried by the hickey 33. In the construction shown in Fig. 4 the conductors, (not shown) are carried straight down the supporting chain and through the hickey 33 to the interior of the socket cluster as before. The sleeve 7 may be closed as by a plug 36 by means of which it is possible to apply the nozzle of a vacuum cleaner to the lower open end of the sleeve and the dust and dirt which may have collected in the bottom of the bowl will be drawn therefrom through the openings 9.

It will now be apparent that I have devised a novel and useful construction of a support for indirect or semi-indirect lighting fixtures which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance shown and described preferred embodiments thereof which will give in practice satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
