SECTIONAL STAND.

Specification of Letters Patent.

Patented Feb.v I6, 1909.

Application filed March 13, 1908. Serial No. 420,787.

T all whom it may concern:

Be it known that I, FRANK G. GBIMLER, a

citizen of the United States, and a resident sccihled relation; also in improvements in .in species of the units themselves, to- U with means for dotuchubly holding the lump socket at the upper end of the stand.

Reference is to he had to the accompanying drcwin s forming a part of this specification, in which similar characters of reference-indicate corresponding parts in all the views. 7

' Figure l is a side elevation of a stand embodyingnry improvements; Fig, 2 it central vertical ection oi the some onun enlarged sonic; Fig. 3 is a cross-section on tholine of 2; Fig. i is plan of one or the units of which the stand is composed Fig. 5 is a. central sectional view through the lower portion of a slightly modified fi'illll of stand 6 is a perspective view oi a modified form unit; Fig. fro-glue:ltury scctionsl view through ester-11d made up of the units wn Fig. 1 Fig. 8 is it view partly in vertical section, showing; a modification of the means for holding the lump; Fig. 9 is a vertical section oi the holder shown. in 8, taken at substantially right angles thereto; and Fi 10 is a view partly in section, showing a. modified form of holder.

Referring more particularly to the -forin of the invention shown Figs. 1 to at inclusive, it will he sec-n that the stand cornprises a base 10, preferably constructed of sheet or cast metal of ornamental form,

fixed unit 11, a series of units 12, relatively shorter than the unit 11, and conductors 13, passing through the base and several units, having connections operating to retain the several units in assembled relation. effected by providing the conductors with a casing 14, preferably of wire spirally Wrapped, which is secured at opposite-ends This is to conical plugs 15, said plugs respectively seating in a. counterpart recess formed in the upper end of the top unit and the lower end of u tubular guide member 16, the latter having the lower portion thereof threaded and is slidublc in an enlarged or counterborcd portion 17 providml in the lower end of the fixed unit ll. The tube 16 is held against rotation by providing gibs at opposite sides, preferably at its up icr end, formed by bondin; the metal outwardly from the body of the tube, as indicated at 18, whichgibs slide in ways 19, iormed in the counterbore o'i'the unit ll. On the thrcnded portion oi the guide tube 16 are :r nut 20, a washer 21,.ond a spring 22 erreneed between the washer sndthe unit 1], this construction obviously providing for the adjustment of the tension on the flexible casing 14 of the conductors, whereby the force. with which the several units are pressed together, and consequently the stiilncss of the stand, may be varied.

The units 12 have concave and convex opposits ends, as in the construction disclosed in my potent ubovc i'c-" erred to, but are, however, modified to the extent of forming; their central apertures of uniform taper instead of elder-gin these apertures in the upper portion of each unit only. In attaching the lump in this form of my invention l. have shown atube 23 which fits over and is secured to the top unit 12, the lamp socket being received and held in the outer end of this tube.

The construction illustrated in Fig. 5 is in 1 all respects the some as that just described, except at the lower portion 01 the stand, where, instead oi'- supporting the unit ll on s. sheet metal base, the latter is replaced lay su .i iortin le s 24 and a casin 25 telescopconstructed, two adjacent units will move as" though rigidly connected together, when the stand isbent ino'ne direction, and when the i ture at one end of each unit only in th direction in which the next adjacent unit turns,

claim as new and Patent:

stand is bent in the opposite direction the This wire-holder is preferably constructed of one piece of wire by bending the wire upon itself intermediate its length, and providing the looped or double portion with a U-shaped member 26, of such size to bind within the tube, and then forming opposed laterally curved loops in the free ends of the wire and joining the extremities thereof, as illustrated in Fig. 8, thus producing the jaws of the holder. If desired, the conductors may be run to the lamp at the outside of the tube by moving the clamping jaws a sufficient distance above the top edge-of the tube.

In Fig. 10 I have shown the wire holder secured within a threaded thimble 23 which replaces the tube 23 and is designed to be threaded directly into a socket.

Having thus described my invention, I

1. A sectional stand composed of a. series of units, certain of said units having curved faces contacting with counterpart faces of the next adjacent units, and the direction of curvature of the faces-of the same unit being different.

2. A sectional stand composed of a series of units 'movable one upon the other, certain ofsaid units having curved contacting faces, with the direction of curvature of one face arranged at substantially right-angles to the direction of curvature of the other face.

3. A holder having oppositely-disposed clamping jaws for embracing a lamp socket,

and a U-shap'ed shank adapted to frictionally engage within a tube.

4. A holder constructed of a single piece of wire bent upon itself intermediate its length and into U-shape for engaging within a tube, and with the free ends of the wire desire to secure by Letters tube, having conical plugs attached to its bent to form oppositely-disposed clamping jaws for embracing the socket of a lamp.

5. A sectional stand composed of a series of units relatively movable one upon the other and each having an aperture, a flexible member passing through the apertures of the units, having means for engaging the stand at one end, a guide tube surrounding and held on the member at the opposite end and having a threaded portion, a nut on the threaded portion of the guide tube, and a spring interposed between the stand and nut.

6. A sectional stand composed of a series of units relatively movable one upon the other, each having an aperture, a flexible member passing through the apertures of the units, a guide tube, pin s secured to the opposite ends of said member, respectively engaging the stand and the guide tube, a nut threaded on the guide tube, and a spring interposed between the stand and nut.

7. A sectional standc composed of a series of units relatively movable one upon the other and each having an aperture, and the bottom unit provided with a counterbored portion on its under side, a guide tube slidable in the counterbored portion of the bottom unit, having a gib projecting from the side thereof engaged in a way in the bottom unit, a flexible member passing through the apertures of the units and through the guide opposite ends respectively engaging with the nut threaded on the tube, and a spring interposed between the nut and the bottom unit of the stand. 1

8. The combination of a stand for carrying a lamp, a tube telescoping over the upper end of thestand, and a wire holder having a substantially U -shaped shank, engaging within the tube, and provided with opposed clamping jaws adapted to embrace the lamp.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
