circular in cross-section and formed prefer` l ably kby a circularly bent sheet or'plate of rolled steel and has its vertical edges abutting against each other, as at 12, Fig. 3. Said member Vl0 extends at its lower end into and is embraced by the upper nular downwardly yflaring steel base" 13 adapted to rest on a floor to which saidfbase maybe Vsecured in any approved Qmanne'r. Themember l0 andthe base lSarerendered rigid with each other in anv ner, as, for instance, securing vtheircontiguous or adjacent portions together., The member l0 is embraced ak steel colla-r la, Vand said vpartsarefwelded together or otherwise T The member lO-hastwo lateral bolt-holes l5 arranged said member and -in line-endwise, `as shown inrigs. -l and 2 and said member is provided below and-al short distance from each hole llwith a lateral holef l6i f wA horizontally arranged bolt has its shank y l Y 17 extending 'loosely through the bolt-'holes l5 inv the `lvtubularfmember l0y andgfl'oosely plates A whicheX- tend circumferentially of said shank atopposite sides respectively and next externally lof said tubular member.` Y Said shank leX- of the -adjacent clamping plate,and a nut l8 is screwed onto said end at` and overlaps said side of said pla-te. The bolt is provided atlits other endl witha square head lQwhich ,L69 end of an ansV 65 approved `IIian- 3'5 by'welding or otherwise `tends'at its vfree end beyond .the outerside is embraced by a correspondingly internally shaped vportion a'of the clamping plate adjacent said head and has its inner end face overlapping vthe outer side of the central portion of said platey so that the vbolt can not turn within theclamping plates A dur- 4ing the manipulation of the nut V18and I tubular member-20 'which'.is circular inV xhere remark that .saidplates are cross-section and extends intothe Vrel-atively I0 `from above and .substantially corresponds: in external diametenwitli -the internal diameter lof the The Vadjustable of a circuhas its vertical edges abutting against each other, as at 22, Fig. 3. T he adjustable member 2O extends above the relatively stationary member 10 in any position of said adjustable member and is provided at its upper end with a head Q3 employ-ed in carryingla desk-top, table, seat or other object (not shown). The head 23 Vconsists of an upwardly flaring steel member which embraces the upper end of the tubular member 20, and said parts are rendered rigid with each other in any approved manner, as, for instance, by welding or otherwise securing their contiguous or adjacent portions together. The adjustable member 20 has two slots 25 which extend from the lower extremity of said member vertically upwardly a suitable distance and are arranged at opposite sides respectively of said member and in line laterally. Said slots register with the bolt-holes 15 in the relatively stationary member 10 so that the bolt-shank 17 extends through the slots.

Each clamping plate A is provided bef low the bolt-shank 17 with a lug 27 which projects inwardly through the adjacent hole 16 in the tubular member 10 and through the adjacent slot 25 in the adjustable member 20 and throughor into a lateral hole 28 formed in an abutment-plate B arranged internally of Said adjustable member opposite the aforesaid clamping plate. That is, two abutment plates B are arranged internally of opposite portions respectively of the adjustable member 20, opposite the clamping plates A, and extend circumferentially of the bolt-shank 17 which extends loosely through said abutment-plates which are spaced longitudinally of the bolt and form the end-portions of a brace which is arranged internally of the aforesaid adjustable member and below the upper end of the relatively stationary tubular member 10 and comprises a cross-bar C which is inverted-U-shaped in cross-section and arranged internally and transversely of the said adjustable member and longitudinally of the bolt-shank. 1t will be observed therefore that the cross-bar C forms the central portion of said brace and said bar straddles the bolt-shank 17 and extends and is interposed between the abutment-plates B which overlap opposite end faces respectively of said bar. Preferably the bar C engages cavities 29 formed in the plates B, and the bottoms of said cavities form seats for said bar which is therefore supported from said plates.

By the construction hereinbefore described, it will be observed that the bolt is provided with means,-viz. the nut 18 and the bolt-head 19,- whereby the clamping plates A by manipulating the nut as required to `tighten 1t against the adjacent clamping plate are caused to clampingly enmember 10 and clamp the adjacent portions of both tubular members 10 and 20 against the abutment-plates B and consequently against the ends of the internal brace comprising said abutment plates and thereby efliciently secure the adjustable member in the desired adjustment. Upon manipulating said nut to loosen it said adjustable member is rendered free to be rcadjusted vertically. that the cross-bar C and the abutmentplates B very effectually brace the adjustable member 2O internally when said member has been secured in the desired adjustment, and that in parts preparatory to the insertion of said adjustable member into the relatively stationary tubular member 10, said plates and interposed cross-bar are placed in position within said member 10 and arranged with the holes`28 in registry with the holes 16 in said` member 10, whereupon the clamping plates A are applied with their lugs engaging said holes 16 and 2S so as to cause the abutment-plates B and the interposed crossbar to be supported from said Yclamping plates, whereupon the bolt is inserted and thereupon the nut is screwed onto the bolt, and lastly the adjustable member 2O is ingage the tubular Vserted within the relatively stationary member 10, and to facilitate the insertion of said adjustable member the abutment-plates B are rounded at their top edges, as at 30, Fig. 1.
