i lower wing, 13,01: each of these hinges is,

inad'e wider 'than :is necessary in order 'to overhang the inside edge of the movable rail, 4. In fact, these wings, 13, are preferably made wide enough to cover the top edges of both lthe back rails, B and 4. The

rthere is'slidably mounted a stem shown at 15, each stem being rigidly attached to the overhanging .portion .of the wings, 13. Thus,

. as the seat, 7, is loweredI after thewings, 9,

.have ,been elevated, the back rail, 4, is per- 'm-itted a .true vertical-movement by being f"guided :by means lof the stems, 15,"sliding 'within the bushings, 14. It will, therefore,

Japp'ear thatftherear rail, 4, is movable between an upper anda lower position `and i in this way, the .appearance of the rear port-i'onof the benchis maintained uniform. It will also be noted that this rear rail, 4,

J x'sl-idesin a .true vertical direction 'and does not'assume an inclined position whenat-the upper Iend fof its movement. n

In order to cause the automatic yelevation .of these'.wings, 9, upon the lmovement of the `',30seat, 7'; to'its'elevated position, I have also mounted these wings, 9, so that they are slidazble to a `slight extent on their supporting. rods, 8.

In addition, teach of these supporting vwings isy cut out as shown atfl6 to permitthe 'application' of a torsion spring, 17, one end of whichis `rigidly secured toeach of,v the ,supportfrods l8, andthe opposite end of each of whichas is shown at 18 is Vmade to engage .respective `wing to normally force 'the wings totheir lowerniost position. f

Mounted on the loutside face of each of the wings is a rod, 19, on which' the sleeve, 2K0, is slidably mounted.'

`Ea'fchfwing,9,' is additionally cutoutplon -itsinside 'face-as is shown a't22 Jtol-accommodate 'this support rod4 structure and is also cutouta4 distancewhich enables the proper sliding fof-the'fsl'eeve,"20, during the raising 5 andlowering of'lthef'seat, 7, aswill now be :described: n. J Eachsleeve,-20,1 has anfupwa'rd'ly project- .ingtonguey 21, into-which 'one end of a rod, k23, is pivotally secured.` The' oppositeuend of each of these rods is pivotally secured to the undersideffaceoffthieseat, 7, as is'shown 'at"24;'; v 1 rffwhentheseat, 7,-is inits'lowerhorizontal ositifoin-each of the 9',{lwil l"be` the positionindioated .inFigflv U'po the2 seat' about; its hinges, lelaclrof-ztlie.'s=j wings will' lbe' elevated tof as- ,stica-lafpcsitionffbecuse1 ef their oolnn' iomwithf'th! seat'v by?.flnieafns ofA the `ping f to horizontal position.,

sleeves, 20, will have engaged the shoulders, 25, forming one end of the cut out portions, 22, and will also have moved these wings to theirrearmost position of movementgtfas is indicated in F ig. 2. i l M `The vinsideback rail, 3, is provided adjacent each wing, 9 with a, stop structure 75 shown at 26 whichfforinsstallsinto "which the wings, 9,`arefmoved when intheir elevated position as has just-been described; These stops are kprovided, in order` to prevent the return of ,the wings to theirl hori 'zontal fpositionl when it 'isjatternpted to lower the seat, 7,- which movement wouldlbecaused bythe torsionp'fthe"springs, 1'7';V

Howevenbefore the seat, 7 has reached- 'a lower upper inclined position, the sleeves,

formed by the cut out portions, v22, and-will also have moved the wings to theposition shown' in Fig. 4 or toy a position out of engagement with'thev stops, .126.

I I-Iowever, the v*seat will have been ineng'agement with the flat top side ofeaolr of *the wings before this disengagenientisfeffected and in this manner the wings be prevented Afrom rdropping ,before 'the seat 95 has' assumed' the' position shownin' IFig:` 4;

` In order to further guard against theA low- -ering' of the wings 5 during the operation; of lowering the seat, l7,1 have notched out the inside face ofthe seat where engages'each 100)` wing is' shown in dotted linesat 27 in Fig. 2 and from this it will follow. that itisfthe vn 'otches 27 which rst engage the wings, k9, at

During the act of lowering seat, 7, each of the wings will be moved out of engagement with the stops, 26, but will be prevented from falling under the influence of the spring 17, by being engaged with the under side-of the seat, 7. However, a subsequent elevation of the seat, 7, to a position slightly higher than that indicated bythe dotted lines in Fig. 2 will permit'these wings to drop by means ofthe springs 17. During this subsequent elevation of the seat, therear rail, 4, will drop vertically because of its slidable connection with the rail, 3, and if then the seat,'7, is again lowered, the latter will assume the position as indicated in Fig. 3. E 1

It will thus appear that comparatively simple means are provided for accomplishing the objects ofthe invention. In addition, the structure is not complicatedy to such a degree as will render its operation uncertain.
