Referring'to the drawings in detail bythe reference characters thereon, 10 'indicatesxa 1 base which is adapted to supporta seat-and a. desk arranged in convenientv relation to eachother. The seat, as-shovvn in Figs. 1,2 and 7, is made up of standards 11, 11a, Which arerigidly secured on the base 10 andeach y of `Which is provided with Aa 'brace 10a secured thereto and to the base 10.` Betweenthe y kstandards 1l, 11a is arranged the seatproper, indicated at 12, andv Which comprises side pieces or rails 12a upon which alia-t or suitablyshaped seat member 12?) is secured. The standardll is provided with avertically arranged seriesrofhcles 13 andthe inner surface of vthe opposite standard is provided with a series. of corresponding depressions 13u. The seat proper supported in any desired position on the standards 11, 1101.b'y means of'a barllA which may'beinserted through any onercf the holes 13 in the stand'- ard 11' and through therails 12a ofthe seat and into Vone of the depressions laronithe opposite standard. At its rear Vend the seat provided With lateral projectionsor lugs 12e which `are adaptedto vcontactvvith the rear-edges of the standards ll, 11a, to hold v the seat ni'elnber 12b in substantiallyhorizontal position, such projectionsbeing formed either on the side pieces 12a or on the'rear edge of the seat member 12b. The seat-12 mayV be adjusted to any desired height by in serting the bar 14 in any one of the holes 13 and depressions 13a. To prevent withdrawal of the bar 14, I provide a cover plate 15 pivoted at 15a to the standard 11 and which normally rests against this standard and is secured thereto by means of a bolt 156 which extends transversely between the standards 11, 11a, the cover plate 15 being notched to fit over this bolt and the bolt having on its end a clamping nut 150. When itis desired to withdraw the bar 14 to change the position of the seat 12, it is only necessary to loosen the clamping nut 150 and turn the cover plate 15 down about its pivot point 15a. The seat is provided with any suitable backrest, indicated at 156, which is arranged between and rigidly secured to the standards 11, 11a.

In the seat arrangement shown in Figure 8each of the standards indicated at 16 is grooved on its inner surface at 16a, and extendingrrearwardly and downwardly from these grooves are shallow notches 166. In this arrangement the side pieces of the seat 12 are each provided with a laterally proj ecting pin or lug 17', which pins are adapted to slide vertically in the grooves 16a and rest in the notches 166. In this form' also the seat adjacent its rear end is provided with laterally projecting pins or lugs 18 which are adapted to contact with the rear edges of the standard 16 to hold the seat in substantially horizontal position. When it is desired to change the level of the seat in this arrangement, it is only necessary to tip the same up in the position shown in dotted lines in Figure 8, when the pins 17 may be withdrawn from the notches 166 and the seat moved up or down as desired.

The desk portion of my construction includes vertical members or standards 20 also rigidly secured to the base 10 and each of which is provided with an upper slot 20a and a lower slot 206. Extending downwardly and rearwardly from the slot 206 i-s a plurality of notches 20c for a purpose hereinafter described. Arranged against the inner surface of each of the standards 2O is an upright support 21 between which is arranged an upper cross bar 21a and alower cross bar 216, which are rigidly secured to the supports 21. The upright supports 21 and cross bars together form a rigid vertically slidable support for the work table later described. A

f rod 22 extends transversely through the supports 21 beneath the bar 21a and through the slots 20a of the standards 20. On one end this bar is provided with a head 22a and on the other end with a clamping nut 226. On the lower end of one or both of the supports 21 is secured a laterally projecting pin or lug 23 and these pins are adapted to rest in any desired one of the notches 200 above mentioned.

By the foregoing arrangement it is eVident that by loosening the nut 226, the supports 21 and the parts carried thereby may be raised or lowered, as desired, the pins 23 being withdrawn from the notches 20o during such raising or lowering operation. Also after the desired adjustment is secured, the pins 23 may be caused to enter the proper notches 20c and the nut 226 can be again tightened to secure the parts rigidly together.

The upper ends of the supports 21 are inclined toward the seat 12 and mounted on these supports is a work table 25 which is adapted to support paper or books or any other work in convenient position for a person occupying the seat 12. In view of the vertical adjustability of the supports 21 relative to the standards 20, as heretofore described, it is evident that the work table 25 may be bodily adjusted up and down relative to the base 10 and to the seat 12 to accommodate persons of different heights. Also the wor table may be adjusted upwardly to such an extent as to accommodate a person in a standing position.

The work table 25 is arranged to rest in an inclined position on top of the supports 21, or of desired the degree of inclination may be varied. Also this table is preferably made so that it can be adjusted laterally relative to the supports 21, in other words, the work table is free from attachment to the supports and is laterally slidable relative to such supports. These results are accomplished by the following arrangement: An angle bar 26 is secured along each edge of the work table, one leg of each of said bars being rigidly secured to the under surface of the work table and the other leg extending downwardly therefrom. Each of the downwardly extending legs of the bars 26 is provided with a longitudinal slot 27 and the lower edge of each is provided with a series of notches indicated at 28. Arranged between each of the angle bars 26 and the adjacent face of the supports 21 is an adjusting member 29. each of which at its upper end is provided with a square hole 30. A rod or shaft 31 extends transversely through the upper ends of each of the supports 21 and is rotatable therein. At each end the rod or shaft 31 is provided with a squared portion 32 which tightly fits in the squared openings 30 above mentioned in the adjusting members 29. The extreme end port-ions on the rod or shaft 31 are preferably round, as indicated at 32a, which portions extend through the slots 27 in the downwardly extending legs of the angle bars 26. A screw 33 is inserted in each end of the rod or shaft 31 to hold the parts in assembled relation. Adjacent their lower ends, each of the adjusting members 29 is provided with a. slot 34 and a rod 35 extends transversely through the standards 21 with its opposite ends arranged in said slot, one end of this rod, preferably the right hand end,

being provided with a clamping nut 35a. One of the adjusting members 29, preferably the leftliand one, is provided with a handle 29a..

It will be understood that the work table is adapted to normally rest upon the inclined upper ends of the supports 21 or upon the upper edges 29h of the members 29. Also it will be apparent from the foregoing description that the work table 25, along with the angle bars 26, is capable of sliding` motion relative to the adjusting members 29. In order to secure the work table in any desired position relative to the adjusting members 29, the latter are provided with laterally extending pins 29o which are adapted to enter any7 one of the notches 28 formed in the lower part of said angle members. It will further be understood from the foregoing that by moving the adjust-ing members around their pivotal support, that is, around the axis of the rod or shaft 31, the inclination of the work table 25 can be varied as desired. That is, by loosening the nut a on the rod 35 and grasping the handle 29a on the adjusting member 29, this member and the ccrresponding one may be simultaneously rotated upwardly to the saine extent.- and after the same have been rotated to bring the table to the desired inclination, the clamping nut- Ba may be tightened to secure the parts in the desired position of adjustment.

Preferably the upper ends of the angle bars 26 are extended somewhat beyond the work table 25 and between such extending ends I provide a tray 37 for receiving pens, pencils or other material, this tray being pivote-d at 37a so that the same remains substantially horizontal even when the inclination of the work table is changed.

At its lower edge the work table, as shown in Figure 1, is provided with an arm rest 38 which extends upwardly and rearwardly in such a position as to conveniently support the arms of a person using the surface of the work table. As shown particularly in Figure 2, this arm rest is preferably curved so as to lit around the body of a person occupy-` ing the seat 12. In the form shown in Figure l, the arm rest 3S is secured to the work table. If desired, this arm rest may be made adjustable as indicated in Figure 5, in which the body portion 39 of the arm rest has secured thereto side bars 39a, the ends of which are turned inwardly to engage any one of a series of depressions 40 arranged along the edge of the work table 25. Also in this arrangement the arm rest is provided with pivot-ed brace members 4l which are adapted to engage in any one of a series of notches formed in notched members 42 secured at each side to the upper surface of the wort; table 25. In this form the arm rest also preferably formed with a curvature at its rear edge to fit around the body of the user.

In order to properly hold papers or books on.=the.upper surface ofeth'ew'orkfftable.25., I provide.' ai workl rest, indicated.-Y ati 43'. This work-.resti comprises :alcentfral .portioniwhich is adapted i tol contact" with the upperf: surface of the worlrtablefand which mayabecov-ered with. rubber or: wood on any i otlieri suitable material'.

VIn order: 'toneffectz this result,V I1' arra-n ge". a: roller 44l adjacent the upper edge of the'tablewhich extends :transversely thereof andztlie 'ends `of which vareimounted in-;bracketsr45 securedto the edgeofthe'worlr table,V the endioibtlie rollergbeing provided with ahandlef46i` forfrotating the same. Ifrfdesired, a supplemental rol-ler 47 maybe provided l and gearedfto" the roller 44.

The arrangement vdescribedis ofparticular applicability to school use, although, of course, not limited to that purpose. The seat 12 may leasily be adjusted to accommodate persons of different heights and the desk can also be bodily adjusted up and down relative to the seat, its inclination can be readily changed and it may be slid up and down relative to its supports so as to bring it into convenient position for a person of any size occupying the seat 12 or in position to be used by a person of any size when in a standing posture.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. A desk construction comprising a base, standards mounted on said base, each of said standards having a vertical slot therein, a worlr table, supports on which said table is mounted, said supports extending downwardly between said standards, said supports at their lower ends having laterally extending I projections and said standards having a series of notches adapted to be engaged by said projections, a rod extending through said supports and the slots in said standards and having a clamping nut on one end, whereby said supports may be clamped to said standards with said projections resting in any desired one of said notches.

2. A desk having a work table and a support on which said table is pivotally and slidably mounted, a member pivotally connected to said support and arranged beneath said table and positioned to contact with and hold said table in any desired position of pivotal adjustment, said table being rotatable and movable laterally relativeV to said support and said member, a notched bar carried by said table and a projection on said member adapted to be engaged in any desired one of said notches by sliding said table relative to its support and means for securing said member in any desired position of pivotal adjustment.
