. sons, in that it is capable of supporting cabinets and other receptacles, in. addition to adjustably su porting a lamp.
With the a ve an other objects in view, the invention further includes the following novel features and details ofconstruction, to be hereinafter more fully described, illustrated in the-accompanyin drawings and pointed out in the appende claim.
In the drawings Figure 1 is an elevation illustrating the invention. g
Figure 2 is a vertical sectional view. Figure 3 rs a horizontal section with the instrument cabinet removed.
Figures 4and 5 are like views taken on difl'erent planes.
Figure 6 is a fragmentary plan view of a portion of one of the arm clamps.
Figure 7 is an enlarged fragmentary vertical section through the upper portion of the edestal.
Fig. 8 is a fragmenta sectional view i1; lustrating the means for rictionally holding the adjustable members of the stand in position.
Referring in detail in the drawings, wherein like characters of reference denote corresponding parts, the improved stand as illustrated includes .a pedestal 10 which is of hollow construction and which rises from a hollow base 11, the latter being ofi'set and weighted upon one side as shown at 12 to provide a counterbalance for the articles supported by the stand. The base is mounted upon suitable castors 13 whereby the pedestal may be conveniently moved, although if desired, the castors may be omitted and the base permanently secured. The edestal is capable of adjustment as to its height and for this purpose includes a sleeve 14, which telescopes within the pedestal roper and this sleeve may be ad ustably held in osition by means to be hereinafter described. A Vertically slidable within the sleeve 14 is a. tubular standard 15, which is provided at its top with a semi-circular or goose-neck extremity 16 which has secured thereto a sleeve 17, the latter being horizontally dis- 17 engage the tubular mem er 18.

posed. Slidable within the sleeve 17 is a tubular member 18, whose outer end has connected thereto by means of a universal joint 19, a substantiall semi-circular or goose-neck section 20. T e outer end of the section 20 carries a lam socket 21" for the reception of an electric l1 ht bulb.
T e sleeve 14 and the orizontal tubular member -18 are yieldingly and .frictionally held in adjusted pose, both the pedestal proper 10 and the position and for this pur- I sleeve 17 are longitudinall slitted. to provide spring tongues 22 whic extend inwardlv the tongues of the pedestal 10 engaging t e sleeve 14, while the ton ues of the sleeve tion, the sleeve 14 is also provided with tongues 22 similar to those just described age the tubularjstandard 15 and serve to yleldingly and frictionally hold the said standard in vertically adjustable posi-.
tion. By means of the sleeve 14 and stand ard 15, the height of the lamp ma be adjusted and it may also be adjusted orizontally by rotation of thestandard 15. In ad-- dition, the universal joint 19 provides for a furthenadjustment of the lam Current is supplied to the Famp through a conductor 23 which extends upwardly through the pedestal from a plug socket 24 and passes through the tubular standard 15, being looped from said standard to the tubular member 18 and further looped around .the universal joint 19, as clearly shown in the drawings. Other conductor wires 25 extend from the plug 24 and connect with out-lets 26 provided in the upper end of the pedestal 10. The conductor wires may if desired be provided with weights 27, while a removable plate 28 is provided in the base 11, whereby ductor wires.
The stand is desired to support various useful articles and for this purpose, the ped estal 10 is provided with grooves 29, 30, and 31, which are formed by spaced beads or flanges. The groove 29 receives a clamp 32 which includes a pair of hingedly connected semi-circular members of a diameter slightly lessthan the diameter of the groove, while a set screw 33 serves to connect the free ends of the semi-circular members in a manner to permit of their adjustment so as to provide a frictional engagement'between the members and the face of access may be had to the conv the groove. Extending from one of. the v members 32 is an armM having at. its outer end a shelf or bracket 35 capable of supportmg some useful article and as the stand illustrated in the drawings is arranged for the use of a dentist, this article may take the form of a water spray heater 36, as
clearly indicated in Figure 1. In this event the arm 34 is provided with a hook 37 for supporting a conductor wire which may lead .from one of the outlets 26 provided in the pedestal 10. The annular grooves 30 and 31 are adapted to receive clam s 39 and supporting spider 44: for attachment to an instrument cabinet 45.
The upper end of the sleeve 14 has a threaded engagement with, a bushing 46, as
shown in Figure 7 of'the drawings and" the tubular standard 15 slides through this bushing.
The invention is susceptible of various changes in itsform, proportions and minor details of construction and the ri ht is hereinreserved to make such 0 anges as properly iall within the scope of the apto pended clalm.
Having described the invention what is claimed is A stand of the character described comprising a hollow pedestal having its lower end enlarged and weighted upon one side thereof, the upper end 'portion of the pedestal being substantially reduced and interiorly threaded, a sleeve member threadedly received and extending within the upper interiorly threaded portion of the pedestal and having inwardly extendin spring members upon the inner sides t ereof, a standard having its lower end portion received within the sleeve member and engaged therein by the spring fingers carried thereon and having its free end portion sub;-
stantially offset and curved, the upper curved end portion of the standard provided with a horizontally disposed sleeve thereon, and a tubular member having its inner end received within the last mentioned sleeve and termi ing at its opposite end in a universally joined offset and curved portion.
