To all wkomz't may concern: In the embodiment herein shown. the .Be it known that I,"Cn.\m.i1s I.

Still a further purpose of thecon- 9, the supporting'frame referred to includes struction is to aflord an arrangement that apair ot' rearwardly extending gu'ides'or makes it possible to construct the frammmrlr members which are preferably in the form 1 5 of the ,ohair of. in le or channel iron, reof channel bars. as designated at 11 and 12, d icin'gg'the cost manufacture and also these being rigidly secured to the vertical imparting additional rigidity to the strucmember 9.

. a we whi forms 3, art of the table carrier, and Arranged for lateral adjustment on the F1 ltlisjgtiohal view on line 10 -10 supporting frame just described, is a carrier upon which is directly mounted the'table el er:refireiroi-chiiracters in the several deslcportion. The carrier comprises a verndicate tliksame parts. tically disposed plate 15 having recesses or:

i one end, while 31 rounding the rod and arranged between the "ration desired, and held channels 16 for engagement with the guides or members 11 and 12, The plate 15 also is provided with flanges 17 which are attached to angle irons IS'arranged on the inner side of the guides 11 and 12. The lugs 19 extend between angle irons 1S and angle bars 20, while lugs 21 are secured to the vertical angle irons 18 already referred; to. The angle irons 18 are bent at right angles at their upper ends to form tions 22, to which are secured the angle :irs 20. The vertical member 9, which is adjustable on the forward leg 5, is secured in position by means of bolts 23, and by this means, thesupporting frame or carrier for the table or desk can be adjusted to any e'lerigidly in such po sition. The supporting'frame or carrier can also be moved in and out on the guide mem-- bers 11 and 12, its frictional engagement with the guide members being suilicient to hold it in any desired position.

-Thc table o!" desk is designated at 24 and has attached thereto angle bars 25 which are pivotally connected at 26 to the aforementioned angle bars mounted on the supporting frame. 27 designates links pivotally connected to the forward ends of the angle bars 20, and having their free ends adjustably associated with-the anglebars on the table 24 To this ,end, the bars 25-are slotted at 28, while 25) designates a rod extending through the bars 25 and links 2? respectivel The rod 2!) has a fixed head-30 at designates a sleeve surlinks 27. 32 designates a second sleeve disposed between the free end of the rod 2!) and the adjacent angle bar 25, while 33 is an adjustable nut threaded ,on'thc end of'the rod and operating, when turned, to tighten tion to the bars 25. By this means, the table or desk ill can be retained horizontal portheparts and hold the links 27 in fixed relaat any desired angle to a horizontal plane, being d sposed horizontally when in its lowermost position.

In a chair of this character, it is desirableto provide means for holding a supply of ink in a readily accessible place, and to this end I employ a socket 34 which is angular and preferably attached to the plate 15. Arranged within the socket 3t is a holder 35 embodying a pair of spring arms 36 which engage the socket 3% at opposite points, and may be turned at right angles to the position shown in Figs. 6 and 10. The holder 35 carries an ink well 3U;which is thus held in a convenient position and can be readily moved out of the way when not in actual use.

I claim asmy invention:

1. In a chair, the combination with a back portion, of a front leg, a table supporting frame including a vertically arranged angle iron adjustably attached to said front leg, a pair of rearwardly extending guides consisting of channel irons adjustably secured 2. In a chair, the combination with a back,

portion, of a front leg, a table supporting frame including a vertically arrai'iged arni adjustably attached to said front leg, a pair of rearwardly extending to-the arm and adjustable back portion, and a table a vertically arranged member or ing engagement with said justable laterally thereon.
