Application filed February 6, 1922.

To all 207mm it may concern:

Be it known that l, Lnnnrrz W. i- LNDElr' sun, a citizen of the United States, residing at Waterbury, in the county of New Haven 5 and State of Connecticut, have invented a certain new and useful Improvement in Portable Electric Lamps, of which the following is a :tull, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a portable electric lamp, the object being to provide a lamp capable of a number of adjustments both in the support, and in the shade portions thereof.

Another object of the invention is to provide for a multiplicity of adjustments of the shade independent of the standard or support; and a still further object is to provide a lamp of such character that the same can be arranged in a vertical position upon a horizontal support, or in a horizontal position upon a vertical support; and in which,

adjustments of the standard or support and shade can be had when the support proper is either in a vertical or a horizontal position.

l-linother object of the invention is to provide a concealed connection in the base of the lamp by means of which the electrical conductor can be quickly and easily connected to or disconnected from the lamp.

Another object of the invention is to hire vide a novel torni oi shade support and also a novel adjustment of the shade upon said support.

lVith these various objects in View the invention consists in the novel features of construction, and in the manner of combining or arranging the same -all of which will be fully described hereinafter and set iorlh in the appended claims.

In the drawings forming part oi this specification Fig. 1 is a view of the lamp with the base thereof resting upon a horizontal support and the conductor disconnected from the base thereof; Fig. 2 is a view of the lamp showing the base thereof arranged upon a vertical support with the lamp and shade adjusted to a vertical posiili U Serial No. 53%,459.

tion; Fig. 3 is a detailed View partly in section and illustrating the shade support; Fig. l is a similar View taken at right angles to the position illustrated in Fig. 3; Fig. 5 is a detailed plan view of the top portion of l:

he shade holder; 6 is an enlarged detail sectional view out the same; Fig. T is an inverted plan view of the base; Fig. 8 is a vertical sectional view of the base show ing the same in a suspended position.

ln the practical embodiment of my in.- vontion, I employ a cast metal base 10 which may be of any desired shape or size and which is covered by a sheet metal base shell 10. To the base is secured a tubular rod or standard 11 through which the conductor wires pass and which carries at its upper end a ball joint 12 and to which in turn connected the nipple 13 of the lamp socket 14, said socket being of the usual or any approved type; and in the present instance 1 have shown a socket provided with a pull chain switch 15.

The tubular standard 11 is surrounded by a thin sheet metal tube 11 which is secured between the lower end of the ball socket 12 and the sheet metal base portion 10.

The conductor wires 16 which are connected to the socket pass down through the ball j oin tend through the tubular standard 11 and are connected to one portion 17 of a separable connectiomthe other or plug portion 18 of the connection being inserted through the opening 19 in the base for the purpose cl? establishing connection with the lamp and it would be noted that the connection is entirely concealed within the base, and said connection being of a separable character, it is possible to quickly disconnect the conductor wires from the lamp so that the lanip can be easily moved, apart trom the conductor wires when desired. A nut 20 is screwed upon the end of the tubular standard and within the base for securely connecting all oi the parts together, it being understood that the wire 16 pass through the tubular standard or rod 11 and also through the nut- 20. The fixed portion of the con nector 17 is rigidly secured to the base from the under side of the same in a socket tornicd therein and opposite the opening 19 so that the connection can be quickly and easily established by inserting the plug 18 through said opening 19; and guide lugs 1O formed on the base on opposite sides of said opening facilitate the proper insertion of the plug 18.

The cast metal base is also formed with an inwardly projecting bifurcated lug 21 for the engagement of the loop 22 arranged at one end of hook 23, so that the lamp can be hung upon. the head or foot portion of a bed or other object as most clearly shown inFig. 2; the hook 23 being hooked over the bed, and the loop 22 brought into engagement with the bifurcated lug 21. The ball joint 12 which constitutes thesubject matter of a separate patent is composed of two parts pivoted together and by means of which the lamp can be adjusted to any position desired with reference to the base, as most clearly shown in. Figs. 1 and 2.

As stated before, the socket 1 1 is of the usual type, and the shade holder is attached to the upper end of this socket, the shade holder comprising a. collar 2% thread ed internally for engagement with the upper end of the socket 1st; and to this collar, the arms are connected at their lower 1 ends, and at their upper ends these arms are connected to a plate 26, the arms 25 being bowed outwardly as shown to permit the incandescent lamp 27 to be arranged between the same as most clearly shown in Figs. 3 and 4:.

The plate 26 is curved preferably on the arc of a circle as shown in Figs. 4; and 6 and is longitudinally slotted asshown at 28. Vorklng in this slot is a threaded stud 29 having the head 29 upon the inner side of the plate and a washer 3O is arranged,

upon the stud 29 upon the outer side of the plate and is provided with inwardly projecting ears 30 which pass through the slot and fold around the head-29 upon the inner side thereof, the purpose of 331d...

washer being to hold the stud 29 against rotation.

The shade 30 .18 preferably made of sheet metal and is of any suitable shape, and up- I on the inner face is preferably enameled white. In the upper end of the shade 30 there is produced an opening-i 31 through which the threaded portion of the stud 29 projects, and a knob or cap 32 is screwed upon the projecting end of the stud 29 for the purpose of securely connecting-tho shade to the shade holder at any of its various points of adjustment, it being readily unuerstood that in order to adjust the shade upon the holder it is only necessary to loosen the knob 32 and then shift the shade and stud in either direction inthe'slot 2-8 of the plate 26 and when the desired adjustment has been obtained the knob 32 can then be tightened and the shade will be held securely in such adjusted position, bending the shade to the plate between the head of stud and knob on the outer end of stud.

It will thus be seen that the shade can be adjusted independent of the lamp, and it will also be understood that the lamp can be adjusted with reference to the base independent of the adjustment of the shade, and by having the lamp" adjustable with reference to the base "and also: adjustable with reference to the lamp, ahnost any desired light control can be had.

It will also be noted that the shade holder being connected directly to the socket, it can be quickly andeasily connectedsto or disconnected from said socket and while preferably used in connection with the base and standard herein shown and-described could be used if so desired in connection with other types of base and standard; in fact, it can be used wherever the standard type of socket is employed and to which the collar 24; can be attached.

It will thus be seen that I provide an exceedingly simple construction of portable lamp capable of a multiplicity of adjustments. and it will also be noted that the neans whereby these various adjustments are accomplished are of a simple and efficient nature, readily understood and easily manipulated.

Having thus described my invention, what I claim is:

1; Ina lamp, the combination with a shade having a centrally disposed opening,

of supporting arms, a curved plate. attached to said arms and longitudinally slotted, a stud movable 111 said slot and projecting .through the opening in theshade, and a knob upon the projecting end of the stud binding said stud shade and plate in locked relation.
