To all'whomz't'may concern: 1

Be it known that LVLTEE VAN vFmnng a citizen. of the United States,"' residing at Parkersburg, in the, county of Butler and State of Iowa, have invented certain new and useful Improvements in Chairs, of which V comprises a pedestal 5, which is preferably the following is a specification" This invention relates to an article of'furniture, and more particularly to acombined chair and" table, particularly designed for us'e by typists, or's'tenographers, and anobject of the invention is to provide a-combin'ed chair and table of this nature which; is 7 strong and sturdy of construction;compris ing apedestal which rotatably supports a chair bottom and back and from which a standard is supported by means of a'circi itf bracket or supporting arm structure whlch standard in turn rotatably supports the car rying arm of the table structure which may be utilized ror supporting 'a' typewrite'r'or for the purpose of taking notes or dictation by a stenographer,

' 'Another obj ect of this invention is to provide a combined chair and tablestructure as specified, which will takeup comparatively little room and, which may be conveniently located so that the person dictatingm'iay walk about without interfering in a y; way -W1t h the stenographer, and which will also permlt the use of thedictator s deskfor permitting the spreading" out of j fthe documents or analogous material being" considered during dictation, allow ng these do'cuments'or other materi'alto be freely scannedby the dictator without interfering in anyway with'the efii-' ciency, of the, stenographer, in that the improved chair and i'table willelimi'nate the necessity of using a partof the dictators desk for supporting'a stenographers note wrench head 24 formed thereon, against the 7 book.

table structure illustrating the mounting .of'theseatvof the chair, and

F is a detail section illustrating the mounting. of the table, i I Referring more particularly to the drawlngs, the improved combinedchair and table endof the arm,9 of a forked supporting bracket structure 10 which comprises a hori zontal arm 11 as well as a diagonal or angled arm 9, these arms merging near their outer ends and terminating in a collar 12 which supports asuitable standard 13. An upstanding bracket arm 14 is formed uponthe bracket; structure 10 near its outer end, and thisupstandingarm 14 is provided with a collar 15 which =en ages about the standards 13 in spaced relatlon tothe collar12. The

collar 15 also forms a support upon'which the collar 16 rests. This collar 16 is formed upon the ,free end. of the angled arm 17, of

the supporting arm structure 18. This supporting arm structure 18 comprises, besides theangled arm 17 K a horizontal arm 19 which has a collar 20 formed upon oneend thereof;

and alining with thecollar 16.7 This collar 20 is mounted, upon the upperend of the standard 13. The supporting armor bracket structure 18 has a collar 21 formed uponits end, opposite to the end upon which the col lar' is formed. The collar 21 is provided with a threaded bore 22 in which is threadablyengaged a stud 23. The stud 23 has a upper surface of which is the hub portion 215 of. the supportingbracket or miter 26.

This miter structure 26 is connected to a.

portion of the stud 23 which projects above 1 the wrench head 24, by a set screw 27 the head of which is countersunk in the hub portion 25 while the stem is threadably engaged in an axial threaded recess 28 formed in the of thetable 29 may be regulated as desired.

The standard or pedestal 5 has its upper end reduced in diameter, forming a shoulder 31, against which the collar 32 which is formed upon the inner end of the horizontal arm llrests. This reduced end of the pedestal 5 is also internally screw threaded as shown at 33, and it receives therein a nut 34,

- --thewrench head 35( of whichen'gages against the upper end of the'pedestal 5 and the upper edge of the bar 32, asclearly shown in Figs. 1 and 2 of the drawings. 7 The nut '35 isprovided withanaxial'bore 36, and with ball races 37 at its, upper and lower ends, surrounding said axial bore 36. The stem 38, of

the seat structure 39. of the chair projects through the bore 36, and-it has a washer 39 mounted upon itslower-end which is'prov'ided with a ball race 40 adapted to engage against the bearing-barrels "41. in" the lower ball race 37 to form a ball bearing connection between the' stem 39 and pedestal 5 at the lower end of the stempfThis washer 39 is held-inplace on the stem 38 by the nut 42."

Thestem 38 has a spider structure 43 formed upon; its upper end whichfo rms 'the' support for the seat bottom 39 and it is also provided with an enlargement 44, atthe junction of the spider arm and the stem, which coacts with the ball race 37 in the upper end-of the nut '35 for confining the bearing balls 45, to

form a ball b'earingor anti-friction engagement between the seat structure and the nut 35* at thelupper end of the latter.

7 The seat portion 39 may be constructed in anydesirable manner, and it has a back 46-0f any preferred construction attached The' connecr' tion between the stem '38 and pedestal 5 permits the chair structure to be rotated about the pedestal'as an axis and the'conthereto in 7 the usual manner.

nectionof the bracket or supporting structure 18 with the standards 13 willpermit the table t'ojbe' swung about upon the axis of the standardf13 andbyproviding the base bear ing collars l6 and 20" the use of thumb screws. or analogous fastening devices is eliminated in that. the two bearing collars will provide suflicientf friction to prevent accidental freerotary movement of thesupporting bracket 18 upon i-the' standard, but willallow comparatively easy movement of the supporting arm under .manual force. The above is'also trueof the connection of the supporting bracket '10 with the pedestal 5. The "position. of the arms 17 and ;19' and also 9 and 11 will'prevent sagging of any part of the table structure with respect to the pedestal 5.

Changes in details may be made without departing from the spirit of this invention, but;
