LIGHTING FIXTURE Original Filed July 25. 1925 Patented Nov. 26, 1929 UNITED STATES PATENT OFFICE I THEODORE J. NELSON AND EUGENE H JOSEPH, CHICAGO, ILLINOIS, ASSIGNORS TO COLONIAL LAMP & FIXTURE WORKS, INC OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS LIGHTING FIXTURE Application filed. July 23, 1925, Serial No. 45,611. Renewed March 9, 1929. 7

Our invention relates to lighting fixtures and more particularly to electric fixtures such as floor lamps, bridge lamps and the like.

Among the objects of the invention are to provide a novel lighting fixture or floor lamp of the above class whereby provision is made for adjusting, i. e., raising or lowering the lamp to suit the desires of the user, at different elevations with respect to the floor or supporting surface and more positively holding the lamp in its respective adjusted positions; to provide a novel counterb-alancing arrange ment for distributing the weight of the lamp on the one side and the weight of the cord and counterweight on the other side of the standard by reason of the arrangement of'a tubular cross arm through which the cord has endwise movement in crossed relation or to extend on opposite sides of the standard whereby tilting of the lamp is prevented; to

provide a curved arm through which the lamp cord including the conductors or wires is movable endw1se and which is so formed and arranged to bind and substantially grip andprovide a rope or cord hanger as described having an extension cord and plug for connection with the house wiring through the medium of a wall socket or the like whereby the fixture and lamp may be moved about to any convenient position or placed to suit the convenience of the user, and to generally improve and simplify the appearance and construction of devices of the character to which the invention relates and to render the same more efficient in operation.

On the drawings, Fig. 1 is a side elevation of one form of lighting fixture or floor lamp constructed in accordance with the invention, and

Fig. 2 is a similar view of another form of lamp embodying the same principles.

Referring to the drawings in detail in which my novel lamp fixture is shown, the invention is illustrated in the form of a floor or bridge lamp, and as seen in Fig. 1 comprises a'standard 3 having a wide base 4: whereby it is held in an upright position.

sides of the standard. This cross arm is illustrated in the form of an inverted substantially U-shaped and uniformly curved tube which may be attached to an ornamental bracket 7 mounted on the upper end of the standard and secured bysuitable clamps 8 and 9. @ne end of the crossarm or tubular guide is preferably located. agreater distance from the standard than the other end and is flared as indicated at 10 while the other arm or leg 11 extends below the clamp 9 and the lower end of the flared or enlarged end 10 of the first arm, is substantially parallel with the standard and is flared or enlarged at its lower end as indicated at 12. I 1 I I A flexible hanger or cord 13 is inserted and extends through the. tubular cross arm 6 and preferably comprises a twisted cord in which are incorporated a pair of conductors as shown and described in prior applications Senal Nos. 612,651, filed January 15, 1-923, and 621,123, filedFebruary 26, 1928, to which reference may be had and in view of which further detailed description-of the flexible hanger or cord 13 is deemed unnecessary herein. However, it may be stated that the hanger 13 is of such size that it snugly fits the bore of the cross arm 6 and by reason'of being bent or curved to conform to the curvature of the cross arm, suflicient friction or binding action will be created to effectively hold the rope hanger or cord in any desired adjusted position.

The outer end of the hanger is connected to a suitable electric fixture illustrated in the form of a lamp 1 1 having the usual electric lamp or bulb attached to the ends of the conductors which are connected to the contacts of the sockets thereof in the usual manner to supply current to the lamp beneath the shade of the lamp 14. In View of the lateral projection of the cross arm 6 from the standard, the lamp and shade are supported at a sufficient distance from the standard to afford ample clearance between the shade and the standard to prevent contact of the shade therewith.

As previously stated, the opposite or inner end of the hanger is supported in a more closerelative position to the standard and depends from the arm 11 along but spaced from the standard 3. At its lower end, the hanger is provided with a counterweight 15 for counterbalancing the opposite end of the hanger, lamp and shade. This counterweight may be constructed as desired, such as in the form of a tassle and is preferably of the type illustrated and described in my prior applications above alluded to. An extension cord 16 is connected to the conductors of the hanger and is provided with a socket or other suitable device 17 for connection with a wall socket in the vicinity of the lamp, such as the usual socket or base receptacle mounted in a wall. By this arrangement, the weight and extension cord provides means for balancing the lamp and shade so that the lamp may be readily adjusted by sliding the hanger or cable 13 through the tubular cross arm or guide 6, and, as before stated, the parts will be held positively in adjusted position owing to the curved or angular bending of the hanger. In addition, by having the cross arm extend on opposite sides of the standard, the

lamp on one side is counterbalanced by the weight of the cord or hanger and counterweight on the other side of the standard, thus preventing the lamp from tipping or tilting over.

In the form of the invention shown in Fig. 2 of the drawings, there is a standard 18 mounted upon a base 19 and at or near the upper end of the standard a cross connection 19 of tubular form, suitably ornamented if desired, is provided to receive and support a tubular cross arm or guide 20. In this form the cross arm has a straight horizontal intermediate portion instead of being curved uni- ,formly and the ends 21 and 22 are curved abruptly downwardly in substantially U- shaped formation providing the angular parts 23 and 24 which permit the hanger 25 to readily move through the same by reason 7 of the curved portions thereof to bind the cord or hanger and hold the lamp at any desired elevation to which it is adjusted. The arms 21 and 22 may be of equal or unequal length and are preferably flared or enlarged at their lower extremities, as indicated at 26 and 27 It will be seen that the arm 21 is located a greater distance from the standard than the arm 22, the same as in the previously described form of the invention shown in Fig. 1 of the drawings and the hanger 25 supports a lamp and shade 28 at the outer end and a counterweight 29 at its inner end through which connection is made by an extension cord 30 to a socket 31 adapted for connection with a wall socket to supply current to the lamp.

With this construction, a fixture is providedin which the parts are supported on opposite sides of the standard by reason of the arrangement of the tubular cross arm or guide having a substantial extension on opposite sides of the standard, so that the lamp on one side is balanced by the weight of the length of cord and counterbalance weight on the other side of the standard, thus preventing the lamp and standard from tipping over. Furthermore, the curved or angular bend of the cross arm through which the hanger and conductors or wires are movable, is so formed or constructed and arranged to bind and substantially grip or hold the hanger or cord at any position to which the lamp is adjusted, thereby holding the lamp 14 28 positively at any desired elevation in which it is desired to maintain the same. It will also be obvious that the support or standard may be moved about from place to place to suit the desires of the user, this portable feature being possible by reason of the extension cord and plug adapted to be connected to a wall socket usual in housewiring, whereby the lamp may be placed in any convenient position by the user.

While we have shown and described our invention in a preferred form, we are aware that various changes and modifications may be made without departing from the principles of our invention, the scope of which is to be determined by the appended claims.

We claim as our invention:

1. In an electric lighting fixture, the combination of a flexible conductor having a weight on one end and a lighting attachment on the other, of a standard, a hollow support on the standard through which the flexible conductor is trained and having cross-sec-" tionaldimensions approximating those of the conductor to resist to a degree movement of the conductor through the support, said'support being bent to increase the frictional engagement of the conductor with the support, 7

and positioned with respect to the standard to dispose the lighting attachment at a greater lateral distance from the standard than the weighted end thereof thereby to increase the stability of the fixture with respect to abase.

2. In an electric lighting fixture, thecombination of a flexible conductor having a weight on one end and a lighting attachment on the other, of a vertical standard, a hollow support transversely arranged on the standard and through which theintermediate portion ofthe flexible conductor is trainechand having interior cross-sectional dimensions substantially approximating thoseof the conductor to resist to a degree movement of the conductor through the'support, said support having bent portions to increase the frictional engagement of the conductor with the support, and positioned ofi-center with respect to the standard to dispose the lighting at tachment at a greater lateral distance from the standard than the Weighted end thereof thereby to increase the stability of the fixture with respect to a base.
