TABLAND suprema Specification of Letters Patent.

Application led January 27, 1908. Serial N o. 412,950.

To all whom. rmay concern:

Be it. known that l, Pari. F.. .Tosi-:m1, a l

eitizen of-the l'nited States. residing at ll aterman. 1n the county of Amador and State ot talifornia. have invented new and useful Improvements in Tables and Supports. of vwhich the following i's a specification.

This invention relates' to tables and-supports'. and more particularly to adjustments for the same; and it has for its objects to provide improvements of this: character whereby the parts or'members of tables or other supports may be relatively moved or adjusted and maintained in the resultant position or positions consequent upon such relative. movement or adjustment.

The invention has for its further partie nlar Objects the provision of improvementg of the character described which sln\ll besuperlor 1n point of inexpensiveiwss, relative simplicity, increased durability of construction and positiveness in operation. and geu- `eral eilieieiafv and serviceability, all in respeet to the devices and constrnrtons ofthe salue general vharaeter heretofore devised.

'lhe invention eonsists in the construction.

provision. eonibimdion. association and application of parts. members: and features. all as hereinafter described and shown in'the drawings.

lu the drawings:--l*`igure 1 is' a perspective viewot' a table or support embodying the invention; Fi". is an enlarged detail elevation. partly' in sm'tion and partly broken away for elearanee of illustration, of a position of the construction shown in Fig. 1, and embracing the improvements constitutin,f r the ii'ivention; and, llig. 3 is; a detail transverseY sectional view. taken upon the line 3-3, Fig. L. and looking in the direc tion of the appended arrows.`

Corresponding parts in all the figures -are denoted by the same reference characters.

liefern-ing with partieulartvte the drawing. the table or support embodying the invention.I shown in full in Fig. 1. and fraglnentaril)Y in the other figures. comprises n relatively movable pedestal or hase A and upright standard or leg ll, the latter of which is shown as teleseoping into a chatnber l extending vertically in the former. The )edestal or base A is provided with suitable egs .5; and the standard or legit earl rie-s a table-top or other element 6, of suitable or any preferred form or type'.

The particular formation. construction, and relative arrangement of the parts or members above described and concerned structurally in the organization of the pedestal or oase and standard or leg B, and their respective adjuncts, have no significance pertinent tothe invention, which latter comprises adjusting means C for relatively moving the pedestal or base A and the standard or leg B and maintaining the same in position of relative adjustment or consequent upon relative movement. Combined with the adjusting and locking means C are opel'- ating means D.

A preferred particular form of construction. provision. combination and relative arrangement and association of parts.' mem# nul features constituting the invent ion is ;1s',follo\vs; -The adjusting and locking means C, in combination with the operating means D. comprise a toothed member or ruck 7 upon the standard or leg B, a toothed member or pinion 8 eonnetrd with the pedestal or hase A. a sha ft t) connected with the pedestal or base A and carrying a. (vorm l0. and a erank l]Y connected \vit.h}the shaft it. The shaft 9 and worm 10 have a common axis. The. standard r leg B is provided with a llongtiuinal 0r vertical chamber 1'2 having a recess 13 otset therefrom and of eoextensive formatiqn; the chamber and re ees; being formed angularly in the standard or leg B witlr respect to one face thereof; and the rack' T is suitably secured within the. ieee-ss 1?, with its teeth extending serially longitudinally of the standard or leg l; v-hereb v the operative face of the rack i' lies.' in a plane at an angle with theA plane of the i'aee of the standard or leg B through which ilnchamber 12 and recess 1? are produced. The shaft this jou 'nailed in a braelee or sleeve 14, one faee of which. namely l5. [its against and is applied to a face of the pedestal or base Formed upon or seeured to the brat-het. or sleeve 14. at the fave 15 thereof, are t\vo spaced lugs or heads lt between which is rotatively mounted the pinion 1w. b v means of a transverse bearing or pin 1T. The worin 10 is applied tothe inner vund of the shaft 9, beneath the pinion 8, and meshes, therewith. The pedestal or hase Patented Dee. es, 1909.

The. lugs or heads 'lik the pinion 8 and the worm i0 lie Within the. l chamber or opening 1S and project tlzerel from into the chamber 12@ the pinion S meshes therewith.

meshing with the rack 7. The lugs or heads 16 project angnlarly from the faire 15 of the. y bracket or sleeve 14, so that the pinion 8 f has a true mesh with thle rook 7 and with the l Worn; l0; there being an angnlarity between the asis of the Worin 10 and n line dialnet rieal of the pinion 8 and cutting the face of the rack which angulo rity is equivalen?V ro the pitch o 'the Worm l0. The. relative nr j rangement in respeet to singularity, con-ti cerned in the positioning of the, rack 7 and l',

` with respect to the worm l0,

above described, permits of a true mesh of 1 the pinion with the. worm; and the direct i nce-to-face. arrangement of the. pinion and i rack enu=e f1 true mesh of the sammthfoperative e-onneriion of the rack pinion and Worm being tions perfect and insuring the f highest working efficiency. A The crank ll n on iles. outer end of the 2 shaft 9 is provid@` with n handle it) am; :x Q counter-weight 20 for the same. the latter g balanring each other in their torsional effect i upon the shaft f). l The pedestal or base A is shown :is rectangular in form, comprising four sides or members ill, 29., 225, and 2,4 surrounding and closely fitting a rectangular standard or lef B. The side or member 1 is that to which or face .25 through which the chamber 12 is formed.

The operation, method of use and advantages of the improvements constituting the invention will bel readily understood from the foregoing, taken in connection with the accompanying drawings and the following 1 statement: The pedestal 0r base A and the l standard lor leg B which telescopes into the ormer, may be relatively moved by the ad- )usting means C to position the ta 'e-top G as desired;'and said adjusting means C will serve, locking means to prevent further relative movement of the pedestal or bose A and standard B until the acinsung moans C are again actuated, such actu-tion being. performed by the operating means D. The handle 19 is properly balanced by the. counter-Weight 20, whereby the, crank 11, and the aforementioned parts of the operatiog means B exert no torsional or unbalancing t cured, the standard or leg B having n side g l The true mesh of the 'pinion ting the face of rack 7, whi

the! adjusting means i are carried 'by the bmrkot or in one operation;
