To all whom t may concern: l

Be it ,known that l, Ganar El. Doniuarmr, a citizen of the United States, residing at Troy, county of Rensselaer, State of New York, have invented certain new and useful Improvements in Electrioliighting Fix# tures, of 'which the following is a specification.

My invention relates to new and useful improvements in electriolighting fixtures, and more particularly of that character or type adapted to support an electric lamp on a work bench, table or other support, or in operative relation to the same, although the invention is capable of use in other situations Wherever applicable.

The invention consists in the novel construction of parts, and the arrangement thereof in operative combination, to be more fully described hereinafter, and the novelty of which will be particularly pointed out and 'distinctly claimed.

I have fully and clearly` illustrated two embodiments of my invention, in the accompanying drawings, to be taken as a part of this specification, and wherein-n Figure 1 is a View in front elevation of a lighting fixture embodying my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1; A

Fig. 3 is a detailed. view of one of the elements shown in Figs. `1 and 2;

Fig. 4 is a detailed view in front eleva tion of a modification of the structure shown in Fig. 3.

Referring to the drawings by characters of reference:

1 designates a distributing or outlet box,

tom horizontal walls 3, 4, parallel to each other, and at right angles tosaid rear wall,

I and vertical end walls 5, 6, parallel to each other and at rightangles to said rear wall and said top and bottom walls. may be made of metal or any suitable 'material. The front of the box is provided with an opening 7, adapted to be closed by a removable cover plate 8, preferably of porcelain or other insulating material. The

cover plate 8 is held in position to close said opening 7 by means of fastenmg screws 9, let through suitable openings 9 m said plate, and threaded at their inner ends into This boxlugs 10 on the inner faces of said walls 3, fl. 55

The plate 8 is provided with openings 81 for passage of electric conductors to the interior of the box.

.ln the form of the invention shown in Fig. 1, the bottom wall 4 of said distributing 6,()

or outlet box is provided with an external. downwardly projecting attaching device, preferably in the form of a cylindrical nipple 11, which is internally threaded at 12 to receive the threaded upper end of a vertical standard 13. The standard 13 may be, and preferably is, provided with a sxiitable base or foot 111 adapted to rest on and be secured to the work table or other support indicated generally at 15. The standard 13 may, orA 70 may not, be tubular, according to whether or not it is employed as a conduit for electric conductors. The nipple 11 is preferably held in place on the wall of the box by inserting one end of said ni )ple throughian opemngfia in said wall, an swaging or expanding said thread on the inner face of said wall, as indicated at 11n in Fig. 2 of the drawings.

The end 'walls of the box are each pro- 80 end wall, and swaging or expanding said end over on the inner face of said wall, as indicated at 16EL in Figs. 1, 2 and 3 of the drawings. lThese nipples 16 'are internally threaded as at 17 to receive the threaded ends of horizontal members 18, 19, respectively, preferablyvin the form of pipe sections or iat tubular members. T he opposite end of the member 19 from that which is connected to the box 1 is connected to a vertical standard 2O by means of-the angle 95 nipple or coupling 21 at the upper end of said standard, thclower end of the standard having a foot 22 to rest on the table 15, or other support. The opposite end of the member 18 from that connected to the nip- 100 ple 16 may be likewise connected to a support or standard (not shown), similar to 'the standard 20, ormay be connected to the nipple 16 of another box 1 (not shown) similar to the box 1 heretofore described. 105

ficient and simple means for supporting one or more of said boxes at desired intervals along a work bench or table'.

Projecting upward from the top wall 3 of the box 1 is a cylindrical bearing pin or stud 23,' which may be tubular it' desired, and secured in place on said wall by passing an end of the stud through an opening 3 in the Wall and swaging or expanding said ends over on the inner face of said wall at 23th At this point I would state that the particular manner described for securing the nipples 11, 16, and the stud 23 on the respective walls of the box 1 is preferable and eiiicient, but is not obligatory, as other means may be employed for the purpose without departing from the spirit and scope of my invention.

24 designates a swivel bracket comprising angularly disposed members 25, 2G, preferably disposed at right angles to each other, and each including a split sleeve, the arms 0r members 21, 25, of which are provided at their free ends with apertured ears 27, 28, respectively, and apertures of which receive adjusting or clamping screws 29, 30, by which the arms of each member may be adjusted toward and away from each other. The opening between the arms 25 of the member 26 is adapted to receive the said bearing pin `or stud 23, and the arms aie adapted to tightly engage the said pin, the degree of engagement being determined by adjustment of the screw 30, whereby the bracket member is rotatably adjustal/e or movable about the said pivot member or stud 23, so that it may be turned on the latter and will be frictioiially held in the. position to which it is adjusted. The arms 2l of the member 25 are adapted to receive a cylindrical pivot member or pin 3l., carried on the rear face of the part 3l, having oppositely disposed arms 32 carrying apertured guide sleeves 33 in alinetiient with each other, and through the apertures of which is Slidably and rotatably carried a supporting member, preferably in the form of a rigid tube 35, at one endlof which is carried a. key socket `36 for an incandescent lamp bulb 37. The conductors 38 for the lamp preferably pass through one or more of the vertical standards 13 or 20 and within the outlet box, and are connected with the lamp by flexible conductors 39 passing through one of the openings 8, heretofore described, and which are inserted in the rear end of the tube 35, thropgh which they pass to the lamp socket, as s iown in Fig. 1.

The arms 24: of the member 25 are clamped in strong frictional engagement by means of the screw 29, with the said pin 31 So that the niember31 may be adjusted pivotally, but will be held in any position to which it is adjusted.

It will be Aseen from an examination of horizontally rotatable on the member 23 to 'provide for lateral or rotary adjustment of the lamp bulb about the longitudinal vertical axis of the standard 13, and the rotation of the part 31 on la horizont-a1 axis in lthe vertical member 25 of the swivel bracket provides for the vertical adjustment of the lamp bulb 37; that is the memf ber may be located at different elevations.

In the modified forni shown in Fig. et the construction is substantially the same as that heretofore described, except that this l'orin is adapted to be used without individual support by means 0f a standard similar to the standard 13, and for'this reason the attaching device 11, or its equivalent, is omitted. This form of the invention is adapted to be inserted at any point in the lower portion ot the member 31", so that.

the part 31 will be prevented from slipping out of engagement with the part 25. The A part 31 preferably extends below the upper edge of the said plug 23, as is clearly/shown in Fig. 2 of the drawings. If it desired to remove the part 31 from ,engagement with the part 25, the plug may be screwed down into the pivot 23 until the upper edge ot' said plug is low enough to permit movenient of the part 31 above the upper end of said plug in a direct-ion lengthwise of the pivot member 31. The plug may have sockets 23d to be engaged by a Spanner wrench for screwing the plug in and out of the pivot stud 23.

From. the above description taken in connection with the drawings it will befseen that I have provided a siinpleand effective arrangement for supporting the swivel membei' of the lamp fixture directly upon the.

outlet or distributing box, andl for supporting the latter without cumbersome anticomplicated` supporting means. It will also be seen that 1 have provided an'ai'rangement wherein the electric feed wires or conductors leading to the distributing box are supported and concealed above, and free from, the supporting table, so that there is no likelihood of said conductors being inthe way of the subject matter of a separate applicatioin' Serial No. 158,801, filed by me under date 0f March 31, 1917.
