F i0'. 6 is a. horizontal section on the indicated line 6--6 of Fig. 1. Fig. 7 is a detailed vertical section .illustrating the construction and connection of arts employed to support the desk or she f. Fig. 8 1s a detailed cross section on the indicated line 8`8 of-F ig. 4 illustrating' the construction of a pen and pencil holder.

In the cons'tlructlon of the device as shown the numeral 10 designates a base preferably formed of iiietall by mplding. The'base .10 may be of any des1red" form or contour and approximates or slopes at its margins closely tothe surface of the flopr 011 whichit is earried'to facilitate sweeping su'ch floor 0r otherwse traversing the same. The base 10 is formed with a adapted to admit screws for fastening said base' to thefloor.' The base -10 is formed with a shelf or 1110212 which in turn is rovided with bolt lioles .13. A pedesta or standard 15, preferably formed of metal by molding, is mounted vertically on a'v shelf or lug 12 andis formed-with a flan e 16 at its lower end and provided with bo t holes registering with the holes 13. Bolts 17 are mounted throu h the registering holes in the shelf 12 an flalge 16, and are secured by nuts A18, thus rigi y connecting the p'cd estal to the base. A late 1.9, referably. of

iligreed or skeleton orm, isl ormed on U1- fixed to the pedestal 15 and -projeets forf wardl andv rearwardly therefrom. A simiate 20` is provided and is arranged ara lel with and outside of the plate 19. locks 21 are arran ed between `end and bottom margins of t e plates 19', 20, and bolts 22 extend through and rigidly corecl side.

of the pedestal 15 and project slightly over the base 10. Flanges 23, 24 are inclined upwardly and rearwardl and a slot 25 is formed. in the pedestal tween said anges. An arm 26, preferably formed of metal by Q A 960,703 y 29 opening upwardly and adapted to receivino and retalning lubricatlng oil. A journa 30 is formed on the arm 26 centrally of the cup 29 and extends upwardly beyond the margins of said cup. A yoke-31 is provided.

and is vformed with a liub 32 on its central portion. The journal 30 is frustum shaped and the bore of the hub 32 is ittedthereto.

A notch 33 is formed in the lower end p,or p

tion of the hub' 32 and is adapted to receive a lue 34 formed on the bottom of the cup 29. l:",l'he' 'lug'.34 is of materially less length than the notch 33, thus providin for a hmited degree of rotation of the luil) 32 on the journal 30 within the cup 29.'A A bolt 35 is mounted in the central portion of the jour- `nal 30 and one or more washers 36 are mounted loosely on said bolt"`and rest on the up )er end of said journal,` lwithin t-he bore o the hub. One or more washers 37 of larger diameter are mounted onthe bolt and rest on the upper face of the hub 32. A nut 3S is screwed on the bolt 35' and ,binds the washers 37, 36 and the hub: 32 to the A .seat bar 39, preferably made journal 30. of spring steel is mounted in notches in the extremity offthe arms of the yoke 31 and is secured thereto by a clamp member 40 overlying the seat bar and bolted tothe yoke.-

The clamp niember 40 is'provided with an' inclined hole in its rear portion and the seat bar 39 is bent upwardl and 4rearwardly and extends through sai ,i hole. This is a provision made for preventing oscillation of the seat bar 39 .on a horizontal axis.

A seat back 41 is provided and is carried on a bracket 42 formed with a socket' 43 adapted to receive and be adjusted vertically op the seat bar. A set screw44 is mounted in the socket 43 and adjustably connects said socket to the seat bar. The bracket 42 may be adjusted lengthwise of or pivotally on the seat bar 39. 'lhe seat bar 39 extends forwardly from the clamp member 40 and then is curved uplwardly and extends rearwardly parallel wit the body ortion thereof in the form of an arm 45. X seat or chair46 is mounled' on and secured to the arm 45 of the seat bar by means ofclam'p members 47 48 bolted together. The clamp 47 is fix to the seat or chair 46 and is provided with a concave rest for the arm 45, while the clamp member 48 is o posite to the clamp member -47 and is provi ed with curved seat partially embracing said arm.l The seat or chair 46 may be adjusted longitudinally or circumferentially of the arm 45. 'The yoke 31 and itsv hub 32, the seat bar 39, clamp member .'back 41,

' engagement of the lug 62" -4to, arm 45, lamp ' members 47, 48, and een 46 may turn on the axis of said hub to the degree permitted by the travel ofthe notch 33 over the lugl 34 tofacilitate entering and leaving the seat. The resilience ofthe bar 39, es ecially at the forward curve thereof,

rovi es a cushion for the seat or chair 46. l

A'bracket 49 is formed preferably of metal by molding and is provlded'with a slot `50V lengthwise thereof. A bolt 5.1 is mounted' throu h the slot 50 of the bracket 49 and isscate in the pedestal 15. By means of the slot 5,0 and bolt 51 the bracket 49 may be aadjusted altitudinally. 'provided with flanges 52, 53 vertically parallel with eachother and crossing the plate 19, and the'` bracket 49 is formed with a groove or groovesl between its side margins and fit- -ting-to said flanges. Thus provision is made to prevent oscillation ofthe bracket 49 on the bolt 5l. 'lhe bracket 49 is formed with a circular head 54 on its upper end and a circular recess or chamber '55 is formed in the outer face of said head. A bracket or spider 56, preferably is formed of metal by molding and is provided with a circular head 57 meeting the head 54 of the bracket 49. The "recess or chamber 55 is frustum shaped and a conical washer 58 is mounted therein and fitted thereto. A bolt 59 is mounted through the washer 58 centrally of the recess 55 and extends through registering apertures in the iheads' 54 and 57 and a nut 60 is mounted o n the inner end-of said bolt and clampssaid members together. A hand wheell 1s lixed to the outer end portion of the bolt 59 and is employed tok rotate said bolt to tighten or loosen the dli'mp of the conical washer 58 in the recess 5 and to tighten or loosen the clamping relations betweenthe heads 54 and 57. The plate or spider 56 is formed with notches in its lower face -and adjacent the conical washer 58 and a lug 62 is formed on the periphery of said washer and is adapted to engage in one or another ofv said washers. A desk shelf or table 63, preferably made of wood, is mounted on the spider or plate 56 and secured thereto by screws 64. One margin of the table or shelf 63 is adjacent tothe conical washer 58 while the'major ortion of said' desk or shelf extends latera y and forwardly across and beyond thea forward margin of the seat 46. In other words,rref' erence to. Fig. 4 will disclose that the seat seat 46 and desk 63 are in aline- Thel pedestal 15 is ment and are in a row at one side of the book box or receptacle. No provision is made for oscillating or adjusting the desk or shelf 63 on a vertical axis but said shelf can be adjnsted on theaxis of the bolt 59 by loosenin the bolt in the nut 60 aud moving said des lto the desired inclination or level position and then tightening said, bolt., The interthe notch ofthe Spider 56 establishes a` s able :relation be tween said spider and desk, and-thewasher. l58 and the conical fitting of said was er in formed in the upper surface of the desk or' `shelfG3,.adjacent the forward margin thereof and a cleat, or strip 66 is mounted on'said marginal'lportion. The cleat'- or strip is formed with a quarter round groove (t7`4 in one corner and is fixed to said marginal pob tion of the desk, in such position that the quai-ter round depression or. groove G7 ,overlies and matches with the half round groove or depression (35, and conjunctively therewith provides a pen and pencil holder in the upper surface of the desk. The strip 66 serves the usefulpuipose of prevent-ing forward movement of pen or pencil from the groove t'a'nd also tends to conceal such articles from the view of persons in front of the desk. L

In the practical use of the desk above described the parts are assembled as shown in Figs. 1, 2, 3, and 4, and adjusted as to the height of the seat from the floor, the height of the seat back from the seat, the inlclination of the seat and seat back, the height of the desk from the floor, and the inclination ofthe desk, to lit. the pupil who is to occupy and use such desk. Thereafter-the pupil turns-the seat in the direction of the arrow in Fig. 4 to the extent permitted by the lug 34 in the notch 33, descends upon the seat 4G and then turns in the direction opposite to that indicated by said arrow into any proper position facing the shelf or desk 63.

The seat isalways entered and departed from at' the same side, the hook box is always on the opposite side of the seat, and the student may shift ithe position of the seat. i'otatively relative t'o the desk (33 into wlatever 'angle is indicated, desired or most convenient. 'It is to be understood that the parts may be constructed and arranged in reveise relations to permit of entering and leaving the seat in an opposite direction' from that illustrated.

It will be understood that the construction illustrated may be modified and changed in numerous particiiiars, and that arts the-reet may be entirely eliminated wit out departing from the scope-oniy invention.
