UNITED STATES PATENT (OFFICE.-

FREDERICK W. WAKEFIELD, 0F VERMILLION, OHIO, ASSIGNOR TO FIELD BRASS COMPANY, OF VERMILLION, OHIO, A CORPORATION OF OHIO.

To all whom it may concern:

.Be it knownthat I, FREDERICK W. WAKE- FIELD, a citizen of the United States and a resident of Vermillion, county of Erie, and State of Ohio, haveinvented a new and useful Improvement in Lighting-Fixtures, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is mechanism for use in supporting the bowls of stone or other translucent material which are now in such general use in connection with semi-direct lighting systems in which the greater, part of the light is reflected from the bowl against the ceiling, while a small part is transmitted through the trans: lucent material of the bowl. These bowls are ordinarily of considerableweight and have to be firmly supported, and as they vary in size, even when nominally rated at the same diameter, it is necessary to have means which can be adjusted slightly to correspond to the variations in size of the bowls and the means must have firm attachment to' the bowl itself.

The present improvements provide a secure means for supporting the bowl and are at the same time simple and relatively inexpensive. Y

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying'the invention, such disclosed meansconstituting, however, but one of various mechanical formsin which the principle, of theinvention may be used.

In said annexed drawings Figure 1 is a view in perspective of the bowl supported by an external ring; F ig. 2 is a section'on the line 2-2 in Fig. 1; Fig. 3 is a view in perspectiveof one of'the hooks mounted upon the ring; Fig. 4:is a similar view of a portion of the ring; Fig. 5 is a perspective view of adjacent ends of the rin g; F ig. 6 isa view in perspective of a similar. type of; b owl,,but supported from within; Fig.

7 is a view similar to Fig. 2 but taken on V the line 7 7 in Fig. 6,;Fig. 8 is a horizon-. tal sectional view" of thering used in. FigsQ 6 and 7; Fig. 9 is a transverse section of the ring shown in Fig. 8; Fig. 10 is. a side elevation of the ring shown in Fig. .8; F 1g.

11 is a perspective view of one of the hooks used in this type of ring. I

Referring now to Fig. 1, there is shown a bowl 1 of suitable material, formed with; a circumferentially extending curved flange 2 at its upper edge. My improvements in-v elude-a concave ring 5 extending completely.

around the bowl and cooperating with the circumferential flange 2 to support the bowl.

'In the form illustrated in Figs. 1 to 3, this ring 3 is split and upon one of the ends is attached a bracket 4 provided with a:

threaded opening 5. On'the other endof the ring 3 there is a second bracket or hook 6 in which there .is mounted a screw 7 adapted to register with :and enter the threaded opening 5 in the bracket 4:, thus drawing the ends of the ring together and clamping the same securely upon the flange 2 of the bowl. It is customary with such bowls to provide three or; more supports the inner side of the curved bracket hooks.

1.0. To engage these hooks over the ring, the lug 9 is first? inserted in the recess or notch 8 and the hook is thenswung around into contact with the outside of the ring,

thus bringing" a second lug 11 adjacent to the upper edge of the ring. 'The lugs 9 which are offflexible material, such as soft brass, are then clamped inwardly Ias illus trated dotted lines: in Fig. 2, thus preventing disengagement of the hook from. i

the ring and maintaining; the same in the desiredfposition circumferentially to the ring. [The bracket hooks 10. are provided at 'their'upper ends with curved portions.

12 adapted tobe engaged by the supporting.

chain :13 asillu'strated in. Fig. 1, and thereare also provided inwardly directe d,. downwardly sloping lamp sockets 14." It is'cu'stomaryin suchbo wls to have three or four;

lamp bulbs-which lie at anglesto radial bowl of this type is provided at its upper edge with an inwardly curved flange 15 within which there is mounted a split ring 16 of semicircular cross section as illustrated, this ring fitting snugly against the inner side of the flange 15, and being securely clamped to the same in the followingmanner. Referring now to Figs. 8, 9 and 10, the two ends of the ring 16 overlap to some extent, the end 17 being compressed to fit snugly and slidably within the other end 18'. Attached to the end 18 at right angles thereto, is a screw'or stud 19 uponwhich is adjustab-ly mounted a set screw 20. The end 11 has movement past this set screw and stud, by reason. of a slot 21 therethrough in which the stud 19 lies. In order to insert a ring of this typein such a bowl, the set screw is loosened and the ring is compressed circumferentially until or a sufliciently small :size to permit of its introduction within the flange 15 of the bowl. The ring is then expanded until it fits the flange 15 snugly, when the set screw is adjusted to maintain it in that po- F sition, in which it is in secure engagement in the bowl.

In Fig. 7 the method of attachment of the supporting hooks 9.2 is shown, these hooks being provided with curved bowls23 adapted to fit snugly within the ring16, where they are held at suitable intervals around the same by means of screws 245 whose holding action may be augmented by the use of solder if desired, the appearance of the ring in. this case not being important as no part of the ring can be seen by a person in the room when the bowl is hung from the ceiling.

.These hooks 22 are provided with curved portions or hooks proper 25, to which may be attached the supporting rods26, and are provided, as are the hooks shown in Figs. 1 to 5, with inwardly directed and downs wardly extending bulb sockets 27.

The two types of supporting rings here shown for bowls of this general type, are notonly extremely inexpensive to manufac ture but are neat in appearance and provide-a very secure engagement of the bowl, and anengag'ement which cannot be secured by any other means now in use unless the means are attached to the bowls before the same are supplied to the workmen in the rooms where they are to be located. Onthe other hand, the presentmeans can be securely attached to any bowl by any workman and need not be assembled before the bowls are delivered to the place where they will be used} Other modes ofapplying the principle of:

ing claims or the equivalent-of such stated means be employed.

I therefore particularly point out and dis-' tinctly claim as my invention 1. The combination: with a bowl havinga circumferential flange along its 7 upperedge, of a split rlng formed to snugly en-:

against such flange, and a plurality of hooks attached to said rin one of said hooks being provided a with a threaded opening adapted toreceive a light bulb. and

maintain the same at a slight angle to the plane of the top of said bowl.

2. The combination with a bowl'havmg a circumferential flange alongits upper :edge,

of. a split ring formed to snuglyengage.

against such flange, and a plurality of hooks attached to said ring and lying within the periphery of said bowl, one of said hooks being provided with an integral extension having a threaded OpBIfiHgthQIGiIi; formed. to recelve a light bulb and maintain; the same at a slight angle to the hor zontal;

3. The combination with a bowl havinga circumferentially disposed, laterally project ing flange of convex exterior aboutits edge, of a split ring of convex lnterior adapted to snugly contact the outside of such flange,

and having alined openings at its ends, and '1 a member adjustably engagingin such openings to securely engage saidring' against;

such flange.

4. The combinationwith a bowl having a circumferentially disposed, laterally pro jecting flange of convex exterior about its edge, of a split ring of convex interior adapted to snugly contact the outside of such flange, and having alined openings at its. ends, a member adjustably engaging in. such openings to securely engage said ring,

against such flange, and a plurality othooks engagmg' said ring exteriorly, thus leaving:

a substantially free interior thereon.
