ARCHIIBALD H. THOMPSON, OF SYRACUSE, NEW YORK, ASSIGNOR F RNITURE TO THE QUAINT ART COMPANY, INC., SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK COMBINED CHAIR AND DESK 0R TABLL Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed June 29, 1916. Serial No. 106,708.

To all whom it may concern:

Be it known that I, ARCHIBALD H. THOMP- soN, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Improvement in Combined airs and Desks'or Tables, of which the followingis a specification.

his invention pertains to an improved combined chair and desk or table, and relates more particularly to that type designed especially for use in school and lecture rooms, though the structure is adaptable for general use wherever a desk is found convenient.

The main object of the invention is to produce a desk wherein the top may be adusted to an desired position, that is to say, that it may e raised and lowered vertically, that it may be tilted to vary its angular position, and that it ma moved back and forth, either when in an inclined or a horizontal position, closer to or away from the occu ant of the chair.

A sti l further object is to structure which, while firm an rigid, is easy of adjustment and this with a minimum amount of manipulation and number of arts.

roduce a Figure 1' is aperspective view of the desk andchair;

Fi 2 a like view of the desk proper and the allied supportin and adjusting parts;

Fig. 3 a longitu inal vertical sectional view of, the structure, the desk body being illustrated in several different adjustments in dottedlines, and the lower portion of the structure being broken away or omitted;

Fig. 4 a transverse sectional view, on the line IV IV of Fig. 3; and 7 Fig. '5 a erspective view of a slightly different em odiment ofthe invention.

Referrin first to Figs. 1 to 4 inclusive, 1 denotes a 0 air of any approved type. Extending forwardly therefrom and in line with one side thereof is a vertically-disposed column 2, said member being framed to the chair body and formin in efi'ect one of the legs thereof. Said umn is of suflicient of t err curvature they will not a to the horizontal limbs 3 are Width and thickness to form an eflicient and stable support for the desk or top, and the adjustable supporting and securing mechanism interposed between the column and desk top.

Surmounting and guided by the column 2 is a vertically-adjustable frame, L-shaped in general outline, and composed of two bracket-shaped members, each having a horizontally-disposed limb 3 and a vertical limb 4. Said bracket members will preferably be made L-sha ed in cross-section and umn 2, said memb the outer face of the column. Secured to said vertical members, adjacent their lower ends, are two cross lates 5 and 6, to which in turn is connected a vertical plate 7, carrying a laterally-extending bolt 8, the plates 5 and 6 being bowed in slightly in order that plate'7 may be brought into close contact with the adjacent face of the column 2. Said column is provided with a verticallydisposed, elongated slot or opening 9 through which bolt 8 passes, a wear plate 10 being provided on the inner face of the column and against which the nut 11 on the bolt may bear when the parts are brought to their clam ed osition.

Inturne nde plates 12, secured to the vertical menfiiers 4, may be employed, said plates taking against the inner face of column 2 an serving to guide the bracketshaped supporting frame when the nut is loosened. ow-shaped stays or braces 13 be secured to the vertical 3 and 4 and by reason be in the way of the occupant of the chair, while at the same time rendering the structure id id, drooping of the horizontal elements being prevented thereby. A cross-bar 14 may be secured to theupper portions of the vertical elements 4, though this isnot essential.

Interposed between and directly riveted two vertically- 15 and 16, each being vided with an elongated slot 17. add plates together with plates 5 and 6 and the bar 14, firmly and rigidly members (3 and 4) together and with said bracket members constitute a vertically adjustable supporting frame for the lid. The lid, designated by 18, will will preferably and horizontal limbs disposed plates preferably be provided with a stolp cleat 19, at its inner edge, and may be provided with an ink-well 20.

Hinged to the under side of the lid, adjacent its inner edge, are two slide bars 21 an 22, said bars ,being arranged at right angles to the limbs 3. 3 and extending through openin 5' formed in the vertical elements thereo Secured to the under side of the lid are two flat or plate- like posts 23 and 24, said posts lying in contact with the plates '15 and 16, res )ectively. Each of said platelike osts will be provided with a slot 25, the s ots lying in an are having as its center the pivot point of the lid to the slide bars 21 and 22. A draw rod 26 passes through slots 17 and 25, and through a spacer and clampin tube 27, the rod carrying at its 28. Then said nut is tilted upon thehinge connection between the lid and the slide or guide bars 21 and 22, and may be likewise moved inwardly or outwardly toward and away from the chair by pulling or pushing on the lid, which causes said bars to move through the openings in the limbs or members 3, 3. \Vhen brought to the desired position, the lid or top may be secured in place by merely turning up the wing nut 28, which causes the posts 23 and 24 to bind against the plates 15 and 1G, and the ends of tube 27 to contact with the adjacent members, in this instance plate 15 and 0st 24. The above arrangement affords amp e range of angular and inward and outward adjustment, and several positions are indicated in Fig. 3. Coupled with the vertical adjustment of the lid, which may readil be ef fected by loosening nut 11, (permitting raising and lowering of the bracket-shaped lidsupportin frame) the adjustment of the lid may be said to be substantially universal.

In Fig. 5 a slight modification is illustrated. In this instance but a single slotted plate, as 29, is employed instead of two, and the single vertically-disposed slotted post 30 is clamped directly thereto by a short bolt and wing-nut 31. A cross-bar 32 ties the outer ends of the horizontal limbs of the bracket-shaped supporting frame together to render the same rigid.

Under both constructions the lid or top is held firmly in position when once adjusted, and the wing-nuts (or nut, as theease may be) are screwed up.

Having thus described my invention,what I claim is: p
