ALBERT SECI-IRIST, OF DENVER, COLORADO, ASSIGNOR TO THE ALBERT SEGHRIST MANUFACTURING COMPANY, OF DENVER, COLORADO, A CORPORATION OF COL- ORADO.

GHANDELIECR.

To all whom it may concern:

Be it known that I, ALBERT SEOHRIST, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Chandeliers; and I do 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, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in lighting fixtures of the chandelier and bracket type, being more particularly 1ntended for use in connection with electric lights of the tungsten type.

One. feature of the invent-ion consists in passing a horizontally'disposed tube arm, forming the support for the electric lamps, entirely through a fixture body suitably supported. This fixture body may be either in direct engagement with the ceiling, or suspended from atube stem extending downwardly from the ceiling any desired distance. By passing the transversely-disposed tube arm entirely through the fixture body and connecting it directly with a vertically-disposed pipe within the fixture body, an exceedingly economical construction is obtained.

Heretofore, so far as I am aware, the

" nearest approach to this invention has been to insert tube arms directly into a fixture body and connect them separately with a metal structure, or cast body, usually concealed by the fixture body, making the construction quite expensive, as compared with my improvement where the lamp supporting tube arm passes directly through the fixture body without difiiculty and without the necessity of placing a separate metal frame or other support for the tube arms, except such as may be necessary to connect the canopy with the ceiling or suspension tube stem above.

Another feature of the invention consists in equipping the outer extremities of the horizontally-disposed tube arm with fittings inserted therein and made readily detachable by means of screws or other suitable attaching devices, whereby the end fitting may be readily removed for purposes of Specification of Letters Patent.

repair or during the original assembling and wiring of the lighting fixture.

Another feature of the invention consists in the employment of what I term a universal coupling for connecting the verticallydisposed pipe members of the lighting fixture, or for connecting the upper extremity of the suspension tube stem with a ceiling member, either in connection with an insulating joint or otherwise, as may be desired.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is an elevation, showing a lighting fixture equipped with my improvements, the fixture body of the structure being directly connected with the ceiling of a room. Fig. 2 is a similar View, illustrating the lamp supporting tube arm and fixture body located below the ceiling and supported from a suspension tube stem, the latter being connected with a ceiling canopy. Fig. 3 is a sectional view of the form of construction illustrated in Fig. 1, the parts being shown on a larger scale. Fig. 4 is a similar view of the construction illustrated in Fig. 2, also shown on a larger scale. Fig. 5 is a detail view of a coupling member.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a bell-shaped fixture body, whose upper extremity is con nected with the ceiling 6 of a room in any suitable manner. This fixture body is provided with a centrally-located, verticallydisposed pipe or rod 7, whose upper extremity 8 is threaded into a boss 9 formed on a spider-shaped member 10, which may be a tripod or insulating joint, connected with the ceiling of a room by means of screws, or other suitable fastening devices. Before applying the pipe 7 a tube arm 12 is passed transversely through openings 13 formed in the opposite sides of the fixture body sufficiently for the purpose, its opposite ends being equipped with end fittings 14 having their inner extremities formed of hollow plugs 15, which are slipped into the opposite ends of the tube arms, the said end fittings having central openings 16 through which the conductors 1 for supplying currentto the lamps pass. The outer extremities of these end fittings are composed of rings 17 from which are suspended links 18, which, in turn, are connected with socket fittings 19 attached to the upper extremities of the lamp sockets 20. This end fitting 14 may be connected with the tube arm extremity in any suitable manner that will permit of its being readily detachable. As illustrated in Fig. 3 of the drawing, this connection is made by means of a cotter pin 21, while, in the construction shown in Fig. 4, the connection is made by means of screws 22. By virtue of the employment of these end fittings 14, it will be understood that access may be quickly gained to either extremity of the tube arm for purposes of repairs or during the original assembling and wiring of the lighting fixture, without the necessity of turning the end fitting as is required where similar connections are attached by means of screw threads, thus making it necessary to disconnect the electric conductors before removing the end fittings. After the lamp supporting tube arm 12 has been passed through the openings 13 in the fixture body, as heretofore explained, the pipe 7 is passed axially through the fixture body, passing through openings 24 formed in the tube arm. The tube arm is securely connected with the fixture body by means of a nut 25 threaded on the pipe above the tube and secured in engagement with the uppermost side of the latter. The lower extremity of the pipe protrudes below the body of the canopy, and is threaded to receive an ornamental nut 3, whereby the lamp holding tube arm 12 is securely fastened to the canopy, as will be readily understood.

The pipe 7 may also be used to carry the necessary wires for an additional lamp socket to be attached to its lower extremity, or for the attachment of a pendant switch to control the remaining lights from a distance below the lighting fixture.

In the form of construction illustrated in .Fig. 4, the fixture body 5, carrying the horizontally-disposed lamp supporting tube arm 12, is located below a canopy 26, secured to the ceiling 27 by means of an insulating joint 28, connected to the ceiling outlet. The lower extremity 31 of the insulating joint consists of an interiorly threaded nipple, connected with an exteriorly threaded male member 32 of a universal coupling 33,

whose lowerextremity 34 also consists of an interiorly threaded nipple which is plain exteriorly and slipped into the upper extremity of the suspension stem 35, the nipple of the coupling being connected with the pipe by a cotter pin 36. The other end of the universal coupling 33 is threaded both interiorly and exteriorly, the interior thread being provided for the attachment of an extension nipple when necessary. This canopy 26 is vertically movable on the pipe 35,

the lower extremity of the tube stem 35, the nipple being connected with the tube stem by a cotter pin 38. The lower extremity 32 of the coupling is interiorly threaded to receivethe upper threaded extremity 39 of the pipe or rod 7, Which passes through the horizontally-disposed lamp or tube arm 12, as heretofore explained. As shown in Fig. 4, a separate nut 40 is applied to the rod or tube 7, where it protrudes below the body of the fixture body 5, and an ornamental nut 41 is threaded on an extension of the rod or tube 7, as best illustrated in Fig. 4.

In the form of construction shown in the last-named figure, the end fittings 14, instead of terminating in rings 17 as illustrated in Fig. 3, are formed into ornamental hooks 42, which form supports for hangers 43, having threaded socket fittings 44 adapted to be connected with lamp sockets. However, these variations in detail havenothing to do with the essential features of the invention-except as to the method of securing the end fittings to the extremities of horizontally-disposed tube arms 12but are simply illustrated to indicate that my improved construction is adapted for use with all varieties of lamp supports.

The tube arm 12 is provided within the fixture body with perforations 2, through which the conductors 4 pass, after leaving the tube stem 35,, as shown in Fig. 4, and after passing through the upper part of the canopy, as shown in Fig. 3.

Having thus described my invention, what I claim is:

1. In a chandelier, the combination with the fixture body, of a tube arm passed transversely through the fixture body and suitably connected therewith, the opposite pro truding extremities of the tube arm being equipped with detachable recessed members through which wires are adapted to pass, for the purpose set forth.

2. The combination with a fixture body, of a lamp supporting tube arm passed horizontally through openings formed in the opposite sides of the fixture body, and suitable means for connecting the tube arm within the fixture body to a suspension tube vertically disposed in the fixture body, substantially as described.

3. The combination with a fixture body, of. a lamp supporting tube arm passed transversely through openings formed in the fixture body and having its opposite extremities equipped with readily detachable lamp supporting members, the said members having shoulder nipples or end fittings slipped into the opposite extremities of the tube arms and secured thereto by suitable fastening devices, and a vertically disposed suspension member entering the fixture body and to which the portion of the pipe within the fixture body is secured.

4. The combination with a fixture body and a canopy, of a suspension means extending below the canopy and into the fixture body, and a lamp supporting tube passed horizontally through the fixture body and secured against the lower extremity out the suspension means, for the purpose set forth.

5. The combination with a fixture body and a canopy, of a suspension tube stem, means for connecting the upper extremity of the suspension stem with the ceiling, includ ing a coupling having nipples protruding from its opposite extremities, one nipple having a threaded connection with the member above it, while the other has a slip connection with the upper extremity of the suspension tube stem below the coupling, and means for connecting the fixture body with the suspension stem, including a coupling whose upper extremity has a slip connection with the lower end of the suspension stem and whose lower extremity is interiorly and exteriorly threaded, and a vertically-disposed member within the fixture body, with which the threaded nipple of the coupling is connected, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
