Tooll whom it meg concern:

, Be it known that I, Gnome D. -BEINERT, citizen of the United States and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Lighting- Fixtures, of which the following is a specification. v

My invention relates to lighting fixtures, and more particularly to an arran ement of such fixtures especially designed or use in connection with gan work-tables. As is well known, such tab es are usually lighted tables and the like, where it is capable of a by means of electric or other lamps susended above them. This arrangement is,

owever, unsatisfactory in certain classes of work, as for instance, in sewin machine requently desirable to bring the lamp much closer to the work, andalso to obtain a greater range of adjustment in directing the light from thelampf onto the work, than is possible where such lamps are suspended from overhadi i .1 I

It is one object of the invention, therefore, to provide a lighting fixture secured to the 'table itself, and arranged so as to be wide range of adjustment in all directions.

A fu'rther object of the invention is to so constru'et the various parts of the fixtures as to readily adapt them for use in connec- T separated to be another. I With the above objects in View, my invention with gang tables formed in sections or units, whereby they may be readily assembled or disassembled in connection with the table sections or units, as occasion may require, as for instance, when the table sections are moved from one place to tion consists in the construction and arrangement' .of' parts hereinafter described, and 'illustratedin the accompanying drawings, in which ,7

Figure '1 is a side elevation of a work table with my improved fixtures applied thereto. Fig. 2 is a transverse section thereof. Fig. 3 is an end elevation on an enlarged scale of one of the junction boxes employed; and, Fig. 4 is a front elevation of one of said boxes with the cover portion removed.

Referring to the drawings in detail in which I have illustrated, by way of example, my invention as applied to sewing machine tables such as are used in factories, 1 desig- In Fig. 1, 2 designates the division linev between two such adjacent sections, such division preferably being spanned by one of the brackets 3 which support the table. These brackets may be adjustably secured to frames 4 in which may be journaled the power shaft 5 carrying the belt wheels 6 over which run belts 7 to the wheels 80f the various sewing or other machines supported on the work-tables. As clearly shown in Fig. 2, these tables may and preferably do consists of two horizontal portions arranged to accommodate two rows of 0 erators, and having between the horizonta l portions a work trough 9, serving to receive and support the work coming from the machine.

,Around the'edge of the horizontal portions of the table, and preferably along the inside thereof adjacent the work trough, I arrange a pipe or conduit 10 having at intervals therein junction boxes 11, so located that there is one junction box provided adjacent each machine or operators posi tion.

Extending upwardly from eaeh f'unction box and supported thereby, is a hol ow post 12, in which slides a standard 13 which maybe clamped in any desired position by means of a set screw 13. To this standard 13 is socured abracket having a flexible arm 14,

supporting at its end anelectric lamp 15, covered by a half-shade 16. It w1ll thus be seen that the lamps 15 may be adjusted to or to the machine, or may be lifted up entirely out of the way as circumstances may require. p

Referring more particularly to Flgs'. 3

and 4, in which I have shown the details of;

my improved junction box, it will be seen that the box comprises a body portlon 11 and a cover portion 21.

preferably fit together on diagonal lines, as

shown at 22 in Fig. 3, and the box is provided at each ,end with sockets l7 having pairs of opposed flanges 20 formed, one on the body pertion, and one on the cover portion, and held together by means of bolts or screws 20. These sockets are adapted to receive the ends of the pipe or conduit These portions any desired position relative to the work,

sections 10, on the ends of which are screwthreaded collars 19, which abut a ainst an and inside of said boxes are connected with strips or plates 25 secured to a block of insulation 26. Branch conductors 27 extend from the strips 25 up through the socket 18 and post 12 and into the lamp bracket, and through the flexible arm 14. In order to allow for the vertical adjustment of the lamp standard and bracket, it

is necessary that the leads 27 be made fiex-' ible and that considerable slack be provided, as indicated at 28. WVith the arrangement above described, therefore, it will be seen that each table section or unit has its own lighting fixturessecured thereto, and that when it is desired to remove a unit from or add a unit to the table, or otherwise change or move said units about, this may be readily accomplished by connecting or disconnecting any pipe section from the corresponding junction box, and also connecting or disconnecting the wires 24 and the strips 25 of the corresponding box. This is a great advantage over the former practice of wiring the work room and suspending the desired lamps above the work-tables, for the reason that with my arrangement only as many lamps are in circuit as are actually required for the number of machines or operators at work, and furthermore the lamps can be adjusted so as to much more effectively light the work. It is thought, therefore, that the great advantages of my arrangement will be readily appreciated by those skilled in the art.

What I claim is 1. The combination with a work table made up ofindependent units set end to end, of junction boxes having removable covers fastened to one edge of each unit, two-part alined sockets projecting from opposite sides of said junction box, one part of each socket being formed on the junction box cover, a lamp bracket supported by each junction box, and a conduit for electric .wires formed of a plurality of pipe sections extending between the junction boxes and supported by the divided sockets so that the number of units comprising said work table may be altered without removing the junction boxes.

2. The combination with a pair of parallel work tables and a work supporting trough between them, of a series of junction boxes secured to the edges of said tables above said trough, a lamp bracket supported on each junction box, and a conduit for electric wires formed of a plurality of pipe sections extending between the junction boxes of each table, and a section connecting the two conduits 3. A junction box comprising a body and a cover (portion, sockets at each end of said box, sai sockets being formed partly on the body and partly on the cover portionof the box, flanges on both sections of each socket to receive screws for fastening the cover on the box, pipe sections carrying electric wires having their ends fitted in such sockets, insulated plates secured in said box to which said wires are removably connected, another socket on the top of said box and formed wholly in the body portion thereof, such socket being adapted to receive a lamp support standard and wires forming a shunt circuit connected to said in sulated plates.

Signed at New York, in the county of New York, and State of New York, this 7th day of December, A. D. 1908.
