SPECIFICATION forming part of Letters Patent No. 258,571, dated May 30, 1882.

Application led March 6,1882. (No model.)

To all whom it may concern Be it known that I, TREFEL GARGEAU, of

Boston, in the county of Sutfolk and State of Massachusetts, have invented certain new and usefullmprovements in Lamp-Stands, ot' which the followingl is a specitication. Y

My invention relates to improvements inthe stein or post of lamp-stands; and it consists in making this stem in three or more parts, the object being to make the length ot' the stem adjustable, so as to adapt the stand for use on a table or sheltl or on the floor, and to enable it to be used as the support for a table-top, bracket, or the like.

In the accompanying drawings, which show a lamp-stand embodying my improvements, Figure l is an elevation ot' a stand adapted to be placed on the floor. Fig. 2 is an elevation showing a portion of the stem removed to adapt the lamp for use on a shelt' or table. Fig. 3 shows the stern in three pieces; and Fig. 4t is a sectional elevation, showing a table-top secured between two of the pieces ofthe stem.

As shown in the drawings, the stem A is composedot' a base-piece, a, a stem, Z), and a lamp-holder, c. The basca is provided with a screw-threaded socket,a, into which the lower end of the stem I) and the lower end of the lamp-holder c are adapted to be screwed. The upper end ofthe stem is provided with a similar socket, b', to receive the lower end of the lamp-holder c.

It will readily be understood that when the lamp-holder c is secured in the base a, as shown in Fig. 2, the lamp is adapted for the table or mantelpiece, and when the stem b is between the holder c and the base a, as shown in Figi, the lamp is adapted to stand on the tioor in any desired part ot' a room. The base a is made sufficiently heavy, by being entirely ot' metal or otherwise weighted, to prevent the lamp from being easily overturned.

It is often desirable to have the table free, and at the same time well lighted, andwhen lamps are depended upon for light it is difcult to arrange them so as to produce the desired result. With my improved lamp-stand this difficulty is obvated, since by adaptingit for loor use the lights can be arranged at any 5o desired points around the table to perfectly illuminate it. -It is also admirably adapted for lighting the -music for a performer on a piano. When placed in the center of a circle of persons reading or sewing thetable-top B is secured between the lamp-holder and the stem b, and it is very convenient for holding books or sewing-materials.

For the bedside ot` an invalid, or for any place away from the table or mantel-piece where a strong light is required, myimproved stand can be used to great advantage.

It is evident that by having the stem in two or more pieces adapted to be connected together the height ot' the lamp can be varied for different positions.

Heretofore, so far as I am aware, noanovable lamp-stand has been adapted for use on the floor, or to support a table, or to be changed from a Hoor-lamp to a table-lamp, and vice Versa; but some independent'support has always been necessary to keep the lamp at the proper height from the Hoor and in the proper position to distribute the lightto thebesteifect.

I am aware that a lamp-holder has been made adjustable as to its elevation by securing to it a rod which could be moved up and down through a shitting-box attached to the base, the friction ot' the packing in the stutiing being depended upon to hold the lamp at any desired position within its limited range. Such an arrangement is shown in PatentNo. 224,449, February I0, 1880, toR. O. Lawton. I therefore disclaim all that is shown in that patent.

I claim as my invention- 1. A lamp-stand to rest on the tloor, having a weighted base, n, a stem, b, and a lampholder, c, separably connected together, so that the stein b may be dispensed with and the base a and holder c be united to make a lamp-stand of the ordinary height for table use, substantially as set forth.,

2. In combination with a lamp-stand composed ot sections adapted to be fastened to each other, a table-top or similar article secured between two of the sections, substantially as and for the purposes specilied.
