Application filed January 11, 1918. Serial N 0. 211,421.

To all whom it may concern:

Be it known that I, ARNOLD J. PETERSON, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Electric-Light- Bowl Hangers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to electroliers, and more particularly to the type commonly known as semi-indirect in which an inverted reflector in the form of a bowl is hung below the lights.

The object of the invention is to improve the construction of the hanger which supports the lamps and bowl, so as to make more convenient the attachment of such lamps and bowl, especially the latter, since it must be occasionally taken down for the removal of dust, dead insects, and other accumulations.

The nature of the invention will fully appear from the description and claims following, reference being had to the accompanying drawing, in wh1ch:

Figure l is a vertical mid-section of a device illustrating my invention. Fig. 2 1s a plan view of the same as seen from the under side, the bowl being removed. Fig. 8 is a fragmentary detail, showing the hinged arm of the supporting spider of the hanger.

In the drawing, the numeral 1 designates the threaded section of pipe forming the main support of the hanger from the ceiling, and through which pass the wires 2 supplying current to the various lamps 3. To the lower end of this pipe is attached a hollow hub 4, having threaded side-holes 5, preferably three in number, to receive bushings 6. In these are screwed straight radial rods 7 two of which may be rigid, and of a length approximating the largest radius of the bowl 8 to be hung therefrom. The bowl, as will be seen, has a constricted rim 9, which rests on the ends of the rods when in supported position. On the bushing 1s mounted the bracket 10, one for each lamp, and the same is held firml in proper position by a nut 11.

One arm of the spider is jointed, as best shown in Fig. 3. To one part of the arm is riveted a piece of sheet metal 12 stirrupshaped in cross-section, and in the extended part is pivoted a short member 13 to swing loosely up and down a limited distance, being stopped when in line with the fixed member of the arm by the stirrup. It is preferably so formed at 14 that it will not swing quite to a vertical position, and as soon as released it drops by gravity to the normal position in line with the other part of the arm.

To mount the bowl is very simple. The operator needs only to place the constricted rim over the fixed arms of the spider and then lift the other side. This action carries the hinged part 13 up until its end passes the rim, when it drops to normal position, to hold the bowl when depressed. To release the bowl the operation is similar, the hinged member being held up momentarily until the bowl is depressed.

The screw-threaded inner ends of the radial arms admit of adjustment in their length to accommodate them to considerable variations in the sizes of bowls. For considerably smaller bowls the rods are easily cut off to the desired length.

In Fig. 3 the stirrup 12 is shown flared at 15. This affords a rather wide 'seat for the member 13 to drop into without obstruction. It also allows the member to swing a limited distance sidewise, as indicated, and thus accommodate itself to flutings or corrugations in the rim.

The construction is such that the hub and radial arms are entirely invisible to the occupant of the room lighted by the electrolier. This in itself is desirable, the luminous bowl being the principal thing. It is also of advantage, since it admits of the hanger parts being made cheaply, of simple and unfinished materials.

Having thus described my invention, I claim:

l. An electrolier hanger, comprising a central hub and screw-threaded spoke arms mounted adjustably therein, one of said arms being divided, its outer member hinged to swing up to less than vertical position, and a stop adapted to hold said arm rigidly against further depression when in line with the other member of the arm.

2. In an electrolier hanger, a central hub, a plurality of straight, rigid radial arms projecting therefrom, and an oppositely disposed jointed arm whose outer member may swing upwardly to less $112M vertical pesiand nuts adapted t0 hold said brackets tion, and downwardly to the plane of the against said hub. 16 other arms, the inner ends of said ai'ms'be- In testimony whereof I afix my signature ing screw-threaded and adjustable i111 said in presence of twe witnesses. hub.
