This invention relates to portable lighting stands or fixtures in which the illuminating element is supported by a stand structure of suitable formation'and height to constitute 5 a floor lamp. For the generallighting efliv fciency required of a'lamp of this character,

"thereis provided a shade of relatively large size.

i To provide improvements in construction 10 whereby the .amount of space occupied by a lamp of the kind described, is minimized, and

by which the rangelof usefulness of the lamp .isjat the same time increased, are the general objects of my invention. The more specific purposes of the invention and as the same ,relate to structural featuresand details, will become apparent aslthe specification of my .linventionproceedsg e y 1 Myinvention is shown in the present application as embodied in a portable stand" of the electric floor lamp type, the height of. same "being .aboutfive feet.

' [The objects of my finvention are accom- ,plished by the new construction, combination .and arrangement of parts described in the following. specification, and illustrated in the accompanying(drawings. The invention is 7 defined in the .appended claims.

It maybe of any suitable material, cast metal being preferred, and it is of such formation. in cross section that a suitable amount of weight is provided at'the Formedintegral with the said head portion A", is afoot A which extends downwardly to the plane of the bottoms of the tips A A and A and outwardly to a'loc'ation slightly beyond the planeof the edges o'f'the tips A and'A, as shown in the sectional view in Figure 2, and in the plan view Figure '3. By

this peculiar construction of the base there is constituted a stable foundation for theretention of the upright support member.

' The lighting-device support member con- .sists of a finished metal column B which is provided at its top portion with a body cup G in which the taped connections of the electric wires which extend from the conductor cord 1 to terminal connections in the sockets 2 are retained. Projecting upwardly from said cup 0 is a threaded stud D, the tunction of which will be presently referred to.

Adapted to be sustained atproper position on said column, is a translucent shade E and which may be of semielliptical formation in plan, as shown in Figure 4. This shade may be made of parchment, or cloth or other suitable material, its edges being secured tothe members E E and E of the wire frame provided therefor. The top members E of this Shade frame are secured to aconnector head E This connector head which may consist of a finished metal disk is provided with a central bore which passes the threaded stud D when the shade is placed in position.

The essential feature of the said shade is, that the connector head E of the frame members E is located in a position a distance from the plane of the rearward side of the shade, and which distance is substantially the equivalent of the distance between the column B and thevertical surface of the foot A of the baseA. While the detail just described is considered preferable, it will be understood that other suitable forms of connecting details maybe used.

' It is obvious that a lamp stand of the construction just described, is capable of affording efficient lighting, and that it occupies less space, is more economical of construction, and requires the use of less material, than do lamps of this class as hitherto constructed.

- In households anddwellingquarters generally, the economy of space isnot only desirable, but is necessary; and moreover, there are certain locations with reference to doors or windows, or to articles of'household furniture, which while unavailable for the use of a floor lamp or table lamp of standard type withits relatively large centrally supported shade, are available to be conveniently and practicably occupied by a lamp stand of the.

present invention. Further advantagesv of my invention are that when the lamp is disposed with its base immediately adjacent to or in closeproximity with the wall, there is not only an artistic effect (the shape PBlfOI'Hlr' ingthe'function of a sconce or shield) but there is obtained a refraction of the :light from the wall, thereby impartingto the room interior an intensified but diffused illumination. At the same time there is no impairment of the efficiency of the light as emanating from the frontal portion of the shade.

Another' advantage of my invention is that of theshade giving; the appearance of being partially sunken in the wall, thereby contributingtothe artistic treatment of the room in which it is-used. My improved lamp while effective and useful in any location, is especially intended for the uses above indiing, and thethickness of base-board finishvings in, household interiors being more or less varied, and which variations may require the lamp stand to occupy positions varied accordingly, I-have provided a stay-arm whose purpose'is toi stayv the lamp stand against tendency to lean fromtrue vertical position. This said stay member also performs the functionfof a handle by which the f lamp stand maybe lifted or moved to desired positionwithout the necessity of touching the shade or column. This stayarm G may be made of cast orjsheet bar metal,- is of curved gagement with the stud D. By means of the finished knob F the connector head may be The surfacealignment and contour of floorclamped and held in tightened engagement with the said stay-arm, and which said stayarm, in turn is clamped and held securely in engagement withthe top of the body cup C. The normal or retracted position of'the stay arm is indicated by the dotted lines in Figure 4;, or it may normally occupy any other position in which it may be disposed within the area of the interior of the-shade.

To stay the lamp stand, the arm Gr is moved rotatively on the stud D, to such position that its end portion rests in contact with the wall,

the position of the wall, for example, being that indicated by the dotted lines 4 in Fig. ure 2.? While this lampstand is essentially a portable device and is intended to be used as such, it is understood that if for any reason itmay be desired to fasten the lamp stand in itsposition adjacent to the wall, anail or 1 screw provided in the wall may be engaged by one of the recesses G It is obvious that by reason of the curvature of the stay. arm, the variations in distance between the wall surface and the column of the lamp are i easily. compensated by' adjustment of the position of the stay-arm. V A stay arm of modified form, may be made of cast or pressed sheet metal in the fanciful form K as shown in Figure-7, the end portions.

K ofwhich extend a suitable distance from the center of the column, 'asshown in the plan View Figure 8. This arm is adapted to 1 be disposed at any desired height on the column, and may be fastened at position by a 'set screw K 7 r I Whereas in the present specification have changes may be made therein, within the scope of the invention as defined by the appended claims,,-without departing from the nature or spirit of my invention or sacri-- 1 ficing any of its advantages.

' What I claim'as my invention, and desire to secure by Letters Patent, is j p 1. A lamp of the kind described comprisi sing a base, a relatively long lighting-device column extended upwardly from one side of the base member, and which said column is provided with a fixture cup'having the usual I threaded stem, an arm of, curved formation in plan and which extends at a right angle toand whose one end is journaled on said stem, aasemiecircular shade one side of which is :open, a connection adjacent to the open side of the shade to engagethe said stem and arm, and a knob screwed on said stem to unite the shade and the arm with the said column, and to hold the shade and the arm in the positions-to which they are adjusted. 2. A lamp standof the kind described,

comprising a base, a relatively long lighting-1; I

device column extended upwardly from a side portion of the said base and which has a threaded top stem, an arm which is pivotally retained on said stem, a semi-circular shade one side of which is open, a connection adj acent to the open side of the shade to engage the saidstem and arm, and a knob screwed on said stem to unite the shade and arm with the column, and to hold the shade and the arm in the positions to which they are adjusted.
