ADJUSTABLE PEDESTAL, FOR COMBINED nEsxs AND SEAT$.

Application filedIleceinber 31, 1923. Serial m5. 683,562.

To all whom it may concern: I Be it known that we, ALFRED D. EDWARDS v and GEoRoE H. ABBOTT, both citizens of the UnitedStates, andresiding at Elgin, inthe county of Kane, and State of Illinois, have invented certain new and:usefulImpr0vements in'Adjustable Pedestals for; Com bined Desks and Seats, of which the fol lowing is a specificatiom j This invention which relates generally to furniture has particular reference to school desks and seats of the kind which use a standard in pedestal form, the purpose being to provide a serviceable, ornamental, and dependable device of this characterfon which may be mounted forplus and minus vertical adjustments a seat,as well as a desk, many of the parts being interchangeably constructed,

, An exemplification of our invention is set forth in the accompanying drawingwhere- Figure 1 is a side view, partly in elevation and partly in section, of the standard, together withsea-t and desk brackets mounted thereon; and

Figs. 2 and 3 are enlarged fragmentary details in section taken, respectively, on lines 2-2 and 3+3 of Fig. 1. i

. The major elements of this invention coms prise a standard or support in the'form of a pedestal A on which are mounted seat and desk brackets B and C, respectively; It is formed in the front wall of the pedestal as is alsoa similar slot (not shown) in its rear wall, these two slots extending fora substantial substance in the middle region of the standard. The general constructionof the standard and its two brackets, as describedabove, forms no part of this invenapplication above referred. to.

:tion, but 'is made the subject of our prior The seat bracket may consist of compan-I ion castings havinga su table configuration on their top for the support of'a seat 'fiX- ture per se. The walls of this bracket are extended downwardly therefrom and rearwardly toward the tapering front side of the pedestal. Thebracket sides-lleach ex} tend toward the'pedestal and provide between, them anfo'pen space such that their rearward edges 12 areaadapted to bear against the standard at 'widelyseparated points. It will be noted from an inspection of the desk bracket Cin Fig; 1 which,in all substantial respects, is the same the seat'bracket, that the rearward edge-s12 which engage with the standard are also slanted in conformity withthe taper of the pedestal walls, this relation being preserved in all the various different tical adjustment.

, The bracket may be heldagainst lateral V shifting upon the'pedestal by providing on the latter some sort of an'element such as arib or spline 13,loca:ted preferably just above and below theslot 7, thisjelement 00 operating with a'complementary groove 18 formed on the bracket. By some such cooperating means as these, the bracket is guided in its adjusting movementswith independence of" any other elements. Due to the chambered construction of the bracket which, in this respectyisj like that ofthe positions of versupporting standard, the slot? is concealed I in all positions of vertical adj ustme'ntof the bracket, its 'walls being properly dimensioned for this purpose. p p j y We prefer to form eachof the brackets of two complementary cast sections whose 0 .5 n meeting edges are in substantial alignment with the plane whichcoincides with the long axis of the standard, As shown in the drawing, the two sections thus uniting. to form the bracketare designated as 14 and 15. Formed at intervals on the section 14 are lugs 16 lapping past thejuncture line 17 formed In the meeting edges of the two sections, an other similar lugs 18Yare extended from the section 15 at intervals to lap past this juncture line, as best shown in Fig. 2. Avery few of such lugs w ll suffice to hold the two sections against'relative shifting movementseither in a direc tion which is vertical or toward "or away from the standard, the lugsbeing preferably grouped in pairs and inengagingrelation. lVith the sections thus assembled, we employ tie rods '19,'asmany a'smay be necessary, to connect them fixedly together.-

-For securing the two brackets upon the pedestal in any desired'p'osition of adjust-1 ment, we provide for each means as follows:

A bolt is inserted through asu'itable lat eral opening formed in the seat bracket front wall which may be thickened, asrepressure.

toward each otherfone from each section manila of the bracket. These webs, together with other similarly extending walls 26,,constitute fontl e vbracket a rear-ward wall which'lies adjacent to the, frontjwall of p the pedestal.

In the assembly of the brackets upon the pedestal the bolt 20 and nut 22 are first secured loosely in place.. In order that the nut may take up'the position shown in Fig. 1, we have p rovided between. the webs 25 and walls 26 aclearance'27 sufficient for the insertion of the'foot end of the nut. The nut body may'ther'eupon rest against the lower edges of the. webs to provide support for the bracket. Additional supporting means, which is also adjustable we provide by a Vertically extending boltBO which lies interiorly of the pedestal, the head31o'f this bolt resting exteriorlythereof'on the cross wall 61' This latter bolt engages within a second threaded opening 32 formedein the head portion of the nut, the axisfo'f this latter opening being transverse to that 'wherein the bolt 20 is received; fBy the use 7 of an appropriate tool, suchas .a socket wrench, the 1 011530 may be rotated to raise o'r lower the nut 22 whenever the bolt 20 is sufiicient loosened for this,purpose. VVhen the bracket is adjusted to the desiredposition, thislatter bolt is then manipulated to i draw the. nut outwardly with the result that the bracket' is' clamped tightly upon the pedestal in a manner to ayoidjall; play or movement; thereupon. When so] adjusted,

the support of the, bracket will be eli'ected through the Vertical bolt 30, inconjunction with the 'nut "22 uponwhose body the webS 25 are rested. Preliminary togr'ea'ching'this final ad ustment, however, the foot 2 facilidescribed.

tates the retention of the parts in their assembled relation, and for this reason constitu'tes a desirable feature ofour-inyention.

The parts just described areduplicated for the desk bracket and accordin ly like reference numerals might be applie to the correspondingset of elements used in connection therewith. These adjusting parts are furthermore interchangeable such that either set maybe used for the operation of the" other bracket." In addition, either bracket may be changed around to occupy the position of the other since the pedestal formation is duplicated on both its front andrear sidesl In the raising and lowering movements of the two brackets, it will be noted that each. is independent of the other. and minus adjustment is provided fOI,'hO\ f 'ever,due" to the sloping character of, the front and rear walls of the'pedestal, so that as the seat is raised", it is also'moved 'rearwardly. In like'inann'er the desk ismoyed forwardly as it'fis raised. WVith an opposite adjustment ofthe two brackets, a'reVersa'lin these lateral movements is: obtained.

A plus These changes in adjustment may be effected conveniently with the aid'ot a' socket wrench,- and the parts to be manipulated aresufiiciently accessible tonot "require any change in position of the occupants. In additiontheiurniture article of our invention maybe adjusted through a rangesuflicient to. adapt the structure to persons of Various 'sizes, and for accommodating persons o'fall ages only two sizes of the arti- "cle war ordinarily" be necessary.

A combined seat and desk of the'kin'd described may be produced at a reasonable costf'In appearanceit is attractive and the few places wheredust, etc, may accumulate are easily .reached for cleaning-so that the article is" advantageous rfrom' a sanitary stand-pointaswellJ I liVe claim: I
