The Yarticle of furniture is in the form of a 'unit or structure including a chair 23 formed of a seat"2| and 'aback 22, a desk`23 provided with arearwardly extending arm rest 24, a pedestal 25 having a vertically adjustable upper section and a stationary lower section, an adjusting member or element 26 for desk 23 and a carrying, receiving and supporting structure or means 2'| for member 2B which is connected to the seat 2| and back 22.

The chair 2G is vshown. by way of example as having the seat' thereof disposed at a downward inclination from front to rearfa'ndits backforrned of a pair of substantially Lshaped oppositely disposed members 28 of angle shape cross sec tion at anyY point throughout their length and a panel 2 9 arranged between and Vextended upwardly from the upstanding partsof the members 28. "These latter are also formed kwith horizontally disposed lower parts w which are anchored to the seat 2|. The members 28 are arranged at the side edges of the seat 2| and panel 29 and y extend against the rear face of the panel and lr` towards the structure as shown in Figure 1. The

part-3| provides the desk 23 and the extension -32 the arm rest 24.

l The lower l'stationary section of the pedestal 25 includes a base 33 and a tubular standard 34 open at each Vend and communicating with the base 33 through the top of the latter. The standard 34 is disposed slightly oif center. with respect to-and isffintegral with base 33. Therearside 35 of standardl34-is formed centrally with a vertical cutout 36 (Figure VIii) which iopens atthe top edge thereof. The rear '-side 35 of standard 34 below and iny alignment with cutout 35 is formed with a pair of superposed aligned openings 31, The base-33 andstandard 34 are of the same'form and arrangement -as the stationary lower section of the pedestal disclosed in my copending applicationgserial Number 139,316, led

April 27, `1937. The Vvertically adjustable upper section of the pedestal `25-includes a tubular post 38 provided at its upper end witha head 3Q which The latter and is anchored vto the lower face of seat 2| eccenvtrically of. the latter. The head 39 will -beo'fthe same form as the head of the upper section of the pedestal vdisclosedrgin my pending application aforesaid. The post 33'is telescopically arranged in standard 34 and is open atits lower end. The

standardv 34 and the post 38 are of octagonal contour in transverse cross sectiong Figure` 12), but the cross Vsectional area of post 38 ismaterially less than Athat of `standard 34. When'post 33 and standard 374 are heldin latching or look-` ing relation, by a means to be referred to, that' portion of the outer "faces of the sides '383, 33h arranged in the standard341are in abutting relationvwith the inner faces ofthe sides 34a, 34b of 1 the standard and the other sides ofthe post 38 are spaced from the other sides `of the standard '34, or in other words, the said other Ysides of the` postare in what may be'termed oating relation with respect to the standard. With reference toFigure 12, it will be seen that the binding en- .gagement of the standard and pedestal is had at rrear side 43 Vis formed withra pair of vertically extending toothed'racks 42 which border the side walls of passage 4|. The adjustable upper section of pedestal 25 is detachably secured in its adjusted positioned by a toothed locking element 43 (Figures 11, 12 and 13) coacting with the walls of cutout 36 andthe teeth of racks 42. The element 43 is in the form of'block44 provided at its upper-end with a pair of oppositely disposed arms 45, 43 extending at right anglesto block 44.

The arm 46 provides a handle piece and latching member. The VVforward yface `of block 44 is squared. ,Therear face of block 44, lengthwise formedlwith aAfpair-of oppositely disposed elon- Y,thereof and at its side marginal portions, is:

ilo

59 spaced from the lower ends of rabbets 41, 48 respectively and a pair of oppositelydisposed short rabbets 52 arranged below rabbets 49, 50 respectively and spaced from the lower end of the block. The rabbets 41, 49 and 5| align. The rabbets 48, 58 and 52 align. The rabbets 41 and 48, the rabbets 49 and 50, and the rabbets 5| and 52 provide the rear face of block 44 respectively, with an elongated rib 53, a short rib 54 and a short rib 55 The ribs are arranged' in spaced alignment. The rabbets 41, 49 and 5| form the rear face of block 44 with a set of teeth 56 for coaction with one of the racks 42. The rabbets 48, 50 and 52 form the rear face of block 44 with a set of teeth 51 aligning in spaced relation with the teeth 56 and for coaction with the other rack 42. Ihe engagement of the sets of teeth 56, 51 with selected teeth of the racks 42 provides a floating joint for holding the post 35 in its desired adjusted position. To prevent block 44 turning relative to post 35, the arm 45 extends through passage 4| and the arm 46 is positioned in cutout 36. To prevent the shifting of element 43 with respect to standard 34 and post 38 and for releasably maintaining the sides 38a, 381U of post 38 in binding engagement with the sides 34a, 34b of standard 34, the element 43 is formed with a pair of superposed aligned threaded openings 58, the walls of which are adapted to be engaged by a pair of headed threaded locking bolts 59 extending through openings 31 and engaging in the openings 58. Lock Washers 68 are provided for the bolts 59.

The adjusting member 26 (Figures l, 2 and 3 to l0) includes a horizontally disposed head 6| and a hollow shank 62 closed at its top, open at its bottom and having its inner side formed, lengthwise thereof, with a slot opening at its lower end. The specific construction of shank 62 will be hereinafter set forth. Shank 62 depends from and is disposed at a rearward inclination with respect to head 6 I. The latter extends at a slight upward inclination from rear to front and includes a forward part 63 having a downwardly curved rear portion 64. The part 63 in vertical section at any point throughout its length is ofi angleshaped contour forming a pair of flanges 65, 66 disposed at right angles to each other. The head 6| includes a rear part 61 having an inwardly anged upstanding web 68 merging at the rear end of its top into a lrearwardly extending flat apertured arm 69. The lower portion of the front of the top of web 68 merges into the lower part of the rear portion 64 of part 63. That f part of the top of the web 68 above the point of mergence of the web 68 with the lower part of the rear portion of part 63 is spaced from the upper part of the rear portion 64 of part 63 to provide a gullet 10. The shank 62 is integral at its upper end with the flanged web 68 and includes a front wall 1|, an inclined top wall 12 formed at its inner side with an inwardly extending flange 14, and a pair of side walls 15, 16 formed at their inner sides with inwardly extending flanges 11, 1'8 respectively. The upper ends of the flanges 11, 18 merge into the end portions of the flange 14. The flanges 11, 18 have their lower ends arranged above the lower ends of the walls 15, 16. The manner of setting u up the shank 62 provides its rear or inner side with an opening or slot. The wall 1| in proximity to its lower end is formed with a pair of screw threaded aligned openings 19. The adjusting member 26 at its upper end and in alignment with its shank has the front of .Part 61 of its .length than arm 8| and is formed with an opening The head 6| of the adjusting member 26 is secured to and transversely of the lower face of desk 23 in proximity to a side edge of the. latter and for such purpose the desk 23 has secured to its lower face in proximity and parallel to its rear edge an angle bar 83 formed of a horizontal ange 84 and a vertical ange 85 depending from flange 84. The latter is anchored against the lower face of desk 23 by the holdfast means 85a. When head 6| is positioned in relation to desk 23, the angle bar 83 extends through the gullet 18, the arms 80, 8| are arranged against the rear face of flange 85 and against the lower face of flange 84, the arm- 69 bears against the lower face of desk 23, the major portion of the length of part 63 of head 6| bears against the lower face of desk 23 and a portion ofthe upper end ofthe flanged web 68 is spaced from the lower face of desk 23. The arm 69 is anchored to desk 23 by the holdfast means 86. The arms 89, 8| are secured to the flange 84 by the holdfast means 81, 88 respectively. The means 81 extends through the opening 82ab in arm 80 and also through an opening 89 in flange 85. The means 88 extends through the slot 82 in the arm 8| and through an opening (not shown) in flange 85. The latter may be formed with openings 90 which are to align with the slot 82 in arm 89 for the passage of additional holdfast means if desired. When members 26 are secured to the desk 23, they will appear as shown in Figure 3. The adjusting member 26 is also what may be termed a combined carrier and support for desk '23. Threadedly engaging with the walls of openings 19 is a pair of inwardly extending screws 99a which function to tighten down member 26 after being adjusted. The member 26 is manually adjusted upwardly and downwardly. The member 26 at the lower end of its rear or inner side is provided with a nose or protuberance 9|)b constituting a fulcrum for a purpose to be referred The carrying, receiving and supporting structure or means 21 (Figures 1, 2, 3, 10, 14, 15, 16 and 20) for the desk adjusting member 26 shown in Figures 1, 2, 3, and 5, or for the desk adjusting member shown in Figure 14 also functions to couple desk 23 or the desk structure shown in Figure 14 with the seat 2| and back 22, as wellas acting, in connection with a desk adjusting member, to sustain the desk above the seat 2|, as well as in forwardly extended relation with respect to seat 2| and back 22. The means 21 includes an upstanding outwardly opening channel-shaped member 9| for receiving shank 62.

.The member 9| is formed of an intermediate vertical portion or part 92, an upper portion or part 93 extending at a forward inclination from the portion or part 92 and a lower portion or part 94 (Figure 16) extending inwardly at right angles to the portion 93. The member 9| is formed with a pair of spaced parallel side flanges 95, 96 extending from its lower to its upper end. The portion 93 is of greater length than portions 92, 94 and has its upper end edge 91 inclining downwardly from ange 95 to flange 96 whereby the latter is of less length than flange 95. The member 9| on its outer face at its upper end is formed with a .rib ,9,8 (FigureA 16) Varranged between A75 flanges 95, 90 and flush .with-edge 91. The flange 99 on its outer side edge .at the upper end of 'the latter is formed with a lug'99provided with a threaded opening |90.` The member 9| is .provided on its outer 4face with a series of parallel spaced ribs ||l| between the anges 95, 96 at the y.lower `part of `'portionr9-3. s The ribs |0| coact latter.

The extensions |48 act a pair of horizontally aligned spaced studs |50. Positioned against the inner ends of each pair of studs |56 is the lower end of an upstanding apertured stationary hinge member |5|. The latter is anchored to its associated studs by the holdfast means |52. The outer ends of the members |38 are apertured and these latter align with the apertures of the members |5|. The apertures in members |5| are arranged in proximity to their upper ends. The outer ends of the members |36 arer interposed between the side walls of the receptacle |36 and the members |5|. Extending through the aligned openings of a member |38 and a member |5|, as well as being suitably connected to such members isa pivot |53. The members |36, .|52 and pivots |53 provide a pair of hinge structuresbetween the desk |28 and receptacle |30. To open the latter, the desk |26 is elevated upwardly from its rear. The pivots 53 extend through the side walls MI, |42 and consist of inwardly extending oppositely disposed headed bolts carrying retaining nuts on their inner ends. The side walls 4| |42 are inwardly flanged at their front ends, rear ends and lower ends. The front and rear walls and the bottom are formedof one piece of material arranged between the side walls, bear against the inner facesof and are suitably secured to the inwardly extending flanges on the side walls. The bottom |41 is formed with one or more openings |54.

An adjusting member common to and for bodily adjusting desk |26 and receptacle |30 in unison is indicated at |55. .The member |55 functions Vfor the same purpose as that of member 26. The member |55 depends from and is disposed at an inclination with respect to the back of receptacle |36. The member |55 corresponds in construction to the shank 62 of member 26. The member |55 has its upper end inclining downwardly and forwardly from the upper end of the rear side` to the upper endof the forward side thereof. The upper end edge vor upper wall of the-member |55 is integral with the outer face of the inturned vflange at the rear end of one of the-sidewallsof receptacle |30. rThe member |55 coacts with-the means 21 in the same manner as the member- 26 does. The member |55 is to have 'associated therewith the clamping-block |20 and the clamping screws |26. f

With reference to Figure 2l, it illustrates a modified form of adjusting member |56, an open top book box |51, a modified construction. of

carrying, receiving and supporting means |58'for the member |56 and a combinedA desk and arm rest element-|59 anchored to the member |56. The latter includes a head |60 corresponding in form and arrangement with respectrto element |56 as the lhead 6| of adjusting member 26. The member |56 -also includes a shank |6| of the same form andl arrangement with respect rto the head |66 as islthe shank 62 with respect to the head 6| of member 26. The outer wall of shank |6| at it's lower end has threaded openings |62 which correspond to the openings v19 in shank 62. The shank |6| has associated therewith screws |63 which correspond to the screwsk 96a associated with the shank 62, but the screws |63 function differently from the screws 96a. These latter are adjusted to engage portion 93 of member 6| for the purpose of adjusting'shank 62 relative to member 9|, whereas the screws |63 although they threadedly engage the walls of end of the shank |6|.. The tight'eneris in the form of an angle-piece and is adapted to engage the member |65 of the means |58 for tightening the shank 6| relative to member |65 of means |58. The tightener |64 functions similarly to that of the screws 90a. The vertical leg |66 of tightener |64 is formed with spaced openings |61 for the passage of the screws |63. The horizontal leg |68 of tightener |66 is to abut member |65. Otherwise than that as stated, the adjusting member |56 will be the same as member 26.

The carrying, receiving and supporting means |56 for the adjusting member |56 is of the same form and arrangement as that of the means 21 heretofore referred to withrthis exception that the upper end terminal portion of the member |65 of the means |58 has its rear face formed with a transversely extending narrow enlargement |69 formed with spaced threaded openings |16 with which are connected binding screws |1| which bear against the flanges |12, |13 of shank The box |51 is of the same construction as the open top box disclosed in my co-pending application as aforesaid. The inner wall |111 of box |51 is connected to a side of the chair back l|15 as at |16. The wall |16 is also connected with the vertical flange |11 of arm |18 of the means |58 by a hanger |19. `The chair seat is indicated at .|80 and to which the lower end of the means |58 is anchored. v

The arrangement of clamping means heretofore referred to in connection with shank 62 and member 9| is employed for clamping shank |6| and member |65 together after the latter has been adjusted.

Wit'h respect to the form including an ope top book box closed by the desk, the screws carried by the adjusting member and the means 26 are adjusted to produce a perfectalignment of the desk. Should a student suddenly sit down on any corner of the desk and exercise a strain beyond that which thecasting or adjusting member was intended for, a bend would -beproduced in the latter.4 Y Formerly, when such-bends occurred the casting was bent back by main force or alignment lat all times of the desk and book box,

keeping. the box square with the level of the seat. IThe foregoing statement relative to t'he screw adjustment with a desk is'employed alone and not as a closure for a book box.

The invention provides whereby when the desk of the form shown, is loosened, itis level and can be shifted to any position which solves a schoolroom problem requiring thatt'he/desk should be level when loosened. This condition means 'that the desk can be lockedY orV can be left loose for students requirements. In other words, if ve or six students are using the desk during the day, they can make the adjustment of the top quickly without resorting at all to the screws. The leverage of the desk top is such that friction tends to keep it up. In other words, the structural arrangement is such that the desk is constantly remaining level which creates a situation whereby the desk remains fixed without its being locked.

With reference to Figures 27 and 28, a book box or receptacle is indicated at |80 and is of the same form as the receptacle |30 shown in Figure 14, with this exception that the top of receptacle 80 is partly closed at its forward end by a narrow closure strip |8| having its edge |82 beveled. The structure shown in Figuresl 27 and 28 includes a combined desk and arm rest element formed from a one-piece flat body |83 having the major portion of its length of greater width and length than its remaining portion. The major portion of body |83 indicatedl at |84 constitutes the' desk and the said remaining'portion of'body |83 indicated at' |85 constitutes the arm rest. The edge |86 of the portion y|81! is beveled. The edge |85 coacts with the bevelled edge |82 to provide'for the elevation and lowering of body |83 fromthe Vrear of the latter. The portion |84 is hinged, 4Vasiat IBI, 'to the box |88 in the same manner as` shown in Figures 17 and 18 with respect to body |21 and box or receptacle |38.

VThe strip |8| forms a forward fiat continuation of the desk provided by the portion |84 when body |83 is in closure position with respect to the top of box |80. The strip IBI may, if denotshown, for receiving writing implements.

The chair and pedestal constitutes what may be termed' the basic part of the unit. The chair is adapted to have detachably and adjustably connected therewith any one of the forms' of the combined Y desk and arm rest elements,

, whether the ele-ment be provided with a book box or not, thereby providing forA the substitution of a different element for the one in connected` position and under such conditions interchangeability is provided with respect to such elements.

The shank which carries the desk or the box closed by the desk is constantly tilted outward by the actual weight of the desk, with or without the book box; There is so much weight at the top of the shank that the latter is always at its extreme point. The two set screws with -the adjusting clamp at the outside merely` serve to tighten the hang of the desk, with or without the box, in that position. The desk with or without the book box remains in a fixed position whether it is locked or not;"the locking of the desk isV to prevent anyloosening of the desk by the student.
