LOUIS ROTH, OF NEW YORK, Y., ASSIGNOR TO STERLING BRONZE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

ELECTROLIER.

Application filed June 27,

To all whom it may concern:

Be it known that I, LOUIS ROTH, of the city of New York, county of Bronx, and State of New York, have invented a certain new and useful Electrolier, of which the following is a specification.

This invention is an electrolier wherein provision is made for hanging a globe or dome directly from a canopy in such manner that said globe or dome may be easily attached, detached, and raised or lowered as required. Furthermore, provision is made for raising or lowering an electric lamp as may be required with reference to the position of the globe or dome, said means operating to securely retain the electrio lamp in a suspended relation to the globe or dome so as to be free from contact therewith, whereby electric lamps of difl'er ent sizes may be used in connection with globes or domes varying in shape and size.

One part of the invention consists of a canopy provided with a plurality of apertures in the form of keyhole slots, combined with a globe, on dome, and a plurality of suspenders, the latter being preferably in the form offlexible chains the links of which are rounded, although other forms of suspenders may be utilized. The links of the suspenders pass through the slots in the canopy and when the weight of the globe is imposed upon the suspenders the links are drawn into the reduced ends of the key-hole slots, thus locking the suspenders to the canopy, although it is apparent that the links may be pulled by hand outof the reduced ends of the slots and then the links can be drawn freely through the enlarged ends of the slots so as to raise or lower the suspenders and the globe or to detach the suspenders from, or attach them to, the canopy.

The invention consists, further, in the combination with a bowl or globe provided with apertures adjacent its upper margin, of a plurality of hangers fitted in said apertures, each hanger being provided with a slotted arm extending inwardly of the globe or dome, and suspenders connected to said slotted arms extending inwardly of the globe or dome, and suspenders connected to said slotted arms of the hangers, whereby the suspenders and the hangers cooperate jointly Specification of Letters Patent.

through Patented June 22, 1920. 1919., Serial No. 307,074.

for connecting the suspenders detachably and adjustably to the globe or bowl.

A further part of the invention consists in providing the canopy with a sleeve which is adapted topass certain conductors for feeding electric current to an lncandescent lamp, said sleeve having a tapering internal thread, combined with a split threaded bushing screwed into the sleeve and cooperating with the conductors for frictionally gripping the same to or releasing the same from the bushing, whereby said bushing may be tightened or slackened for the purpose of retaining the conductors in fixed relation ting the conductors to slide through said canopy to the end that the lamp be raised or lowered within the globe as required.

Other features and advantages of the in Vention will appear from the following description taken in connection with the drawings, wherein- Figure 1 is anelevation with parts in section of an electrolier embodying this invention. Fig. 2 is a horizontal section taken in the plane of the dotted line 2-2 'of Fig. 1 looking upwardly, the parts being shown on an enlarged scale. Y

Fig. 3 isa detail perspective view of one of the hangers.

A designates the canopy, B a globe or bowl, and C are the suspenders attached to the canopy and the bowl or globe whereby the weight of said globe is suspended directly from the canopy.

The canopy is a metal fitting, composed of a cast piece, or a metal spinning or stamping, the mode of producing said canopy not being material. As shown, the canopy is hollow in construction to produce a top flange a and a pendent central member a,'the latter being formed at the center with a sleeve b. The canopy partially houses or incases the junction box D, and means suitable for the purpose are provided for fixedly attaching the canopy in position, the means shown being the screws 0.

According to this invention, the canopy is provided with a plurality of slots E, a suitable number being formed in the central pendent member a, three being shown in Fig. 2. Each slot consists of an eye e and to the canopy or of permitthe dome has a tendency to draw penders into the narrow parts of the slots,

an elongated part e, the slot being of the :kind termed a key-hole slot. The slots are spaced equi-distantly in the canopy,

and they open through the underside of said canopy so as to be easily accessible.-

The suspenders C may be composed of rods, chains, cables, or otherwise, but itis preferred to use chains the links of which are globular in form and are flexibly connected. The links are adapted to pass through the eyes 6 of the key-hole slots in the canopy, and after sliding therein to the required positions said. links are shifted into the narrow parts 6 of said slots, as a result of which the flexible chain suspenders are locked to the canopy. The slots are so positioned in the canopy that the pull of the flexible suspenders and the weight of the susand thus provision 1s made for arresting the chains from accidentally slipping in the slots so as to become detached from the canopy except by manual manipulation.

The globe or dome B is of any desired shape and dimensions, it being preferred to use a '-dome of transparent or translucent material such as glass. Said dome is shown as closed on the bottom and open at the top, the dome being provided with a plurality of apertures 7" near the upper margin thereof. Said apertures accommodate the hangers F, one of which is shown detached in Fig. 3 and two are fitted to the globe, see Fig. 1. Each hanger is composed of a piece of metal bent at two .points intermediate its ends to produce an angular part f and an arm f, one end portion of the hanger being provided with a head 9 and the arm f having a slot 715 enlarged at the end 'to form an eye it, said slot 72, it being of key-hole formation. The angular part I of the hanger. is passed through an apertare f of the dome so that the head 9 lies, in snug relation to or in contact with the" globe on the outside thereof, whereas the .arm f of said hanger extends inwardly of the globe,

at an angle to the inner face thereof,see Fig. 1. he hanger is thus fitted detachably to the apertured globe sov that the slotted armis conveniently positioned for 'the attachment of the flexible Suspender;

hanger may be and prefpresent a neat appearance.

One of the lower links of the flexible suspender passes through the eye h of the hanger and is drawn to the requiredlength, after which the link of said suspender is slipped into the reduced-part or slot It, thus providing a detachable and adjustable'con-f nection between the suspender and the globe, said slot occupying such a position in the hanger that the weight of the globe draws the flexible Suspender into the slot is. connected in the usual manner.

'is in concentric relation order to raise .or lower the lamp within of the, globe.

suspenders attached to globe, the :upper portions of said suspenders.

in order to retain the suspender againstaccidental separation.

Through the sleeve 2) of the canopy passes the conductors G which carry a lamp socket i, to which an incandescent lamp I Said sleeve .7) is provided with a tapering opening in which'is tapped a female thread, pro ducing a tapering threaded opening.

male threaded bushing J is screwed into this threaded sleeve,.said bushing being split as 1 and 2 and the lower part of the bushing being provided with a knob or knurledoperating piece j. The bushing to the canopy and the sleeve '1) thereof, thus permitting the conductors G to pass through said bushing. When turned in one direction, the bushing shown in Figs.

is closed by the tapering thread in the sleeve and itithus acts to grip the conductors Gr for suspending the lamp in a desired relation to the dome, but by rotating the bushing in the opposite-direction, conductors, thus permitting said conductors to slide through the bushing and sleeve 1iln t e dome, whereby lamps of different sizes may be attached to thesocket and adjusted to occupy a desired relation to the globe, without being in actual contact therewith.

From the foregoing description it will-be seen that the globe-may be raised or lowered as required with reference tothe canopy, that one or .more suspenders can easily be detached so as to swing the globe aside on one or two suspenders, that the globe may be mounted or dismounted easily and quickly, and that the lamp can be raised or lowered without disturbing the position The devices are simple, efficient, reliable and economical of manufacture.

Having thus fully what I claim as new, Letters Patent :is:-

1. An electrolier embodying a ceiling canopy positioned for substantially incasing a ceiling junction box, said canopy being provided with a plurality of key-hole slots, a globe, and a plurality of flexible said globe, said flexible suspenders being'adjustably and detachably connected with the slotted portion of said ceiling canopy.
