expelled from the mouths of .the children lduringzsuch drills. The effective disposal l of. this refuse yis necessary .and important fnot only for sanitary reasons, but also to prevent VV20 Auntidy conditions in the school room, or Vother Vquarters where theinstruction isbeing given.V Oney of the objects of the invention is to provide `a supporting rack, which may beV placed in any desired positionin a school room, so that the .children may be conveniently assembled about it for the desired tooth-brush drills.v A furtherobject istoprovide a stand of the character mentioned, constructed so that it may be 4collapsed or folded into compactform, for convenient storage `when not required.

Theinvention will be hereinafter fully set forth andpar'ticularly pointed out inthe cl'aims. v i

In the accompanyingndrawingz- Figure 1 is a side elevation illustrating a rackc'onstructed in accordance with the in@ ,ventionl Figure2 is'an end .view thereof.

V- Y Referring'tothe drawings, A and A represent two end frames' or uprights each consistingfofside'ibarslO', Arigidly connected at their lower portions by a cross bar -11,

and near thev upper portion by a second cross bar 12, which serves as atrough support.

cross bar 11'vand` divergehoutwardlyptheir extremities being bent as indicated at 13 to provide supporting feet.A Projecting above the plane ofthe bar, 12 are trough engaging farms'v 14,; which diverge upwardly and outwardly, as'show-n.

The uprights A and A are connected'by side bars 15, the extremities of which-are movably connected-'to the side barsbyy pivotsl, at positions preferably "immediately above the plane of the cross barsv11. Said side bars 15 are connected with the'side members 10 ofthe uprights by. meansof brace members B. Each brace member consists `of two members 17 and 18 pivotally connected together at one end, as indicated at 1,9,1-the other vend of the member 17 being pivoted to-a sidebar 15, as indicated at 2O.k The other end of the member 18 is offset, as indicated at 21 and pivoted to a sidelO of oneof the uprights, as indicatedv at'22.` It willbenoted 'that the uprightsA and Aare-wider vat the bottom'than at the top,'and that the offset 21 is provided so that-the member "18 Vwill lie approximately over the adjacent sidebar 15 when tlieraclz is in open position. `Each member 17 of the brace members vis provided with a flange 23, which engages the adjacent portion of the member 18, to limit the relative pivotal movement ofthe'arms 17 f and 18.

tis preferred to use but two ofthe braces B. The member 18 of one brace issecured to a side member of an upright A and the member 17 of said brace being connected to the adjacent side bar 15. 'The memberw18 of the other brace isV secured to a sidemember .10 of the upright A', but on the other side -of the rack.'y And? the arm.17-jof-said brace is connected to the adjacent side bar 15. K Thus, i

but one'bracemeinber is employedv foreach upright, the twoY brace,'membersbeingwlo- Located 'between thearms 14 of theA .two uprights, and resting upon thecross bars 12 thereof is a trough T,whichmay,if desired, 'be' providedwith 'a discharge'opening 24 in 1 In' practice, it is preferred tof construct the parts of the. raclrfof flat metall strips, as shown, although the. inventionis not limited its bottom wall, normally clos'edby la plug 25. The parts thus far described are shown as in this particular. Vlien it is desired to employ the rack, for instance, to support the trough T for a tooth brush drill, the upper ends of the rack while in folded position (Figures 3 and 4)' are grasped by the operat-or and drawn apart. The uprights will hinge upon the pivots 1610i the side bars l5, and theirupper ends may be moved outwardly until stopped by means of the brace members B, which automatically unfold and take the positions illustrated 4in AFigure l, the separating movement of the uprights being limitedl Y tir-ne,preferably` immediately after the drill is over. When .there isfno further use lfor the L V.trough and rack, ithe trough is removed and `cleansed 'in any desired .sanitary manner, and

the .rack is foldedfby bringing theupper ends toward Eeach.o.tl'1er,iso, that .the brace members Y will foldupontheirpivots 1.9, the vparts-as'- suming the jpositions illustrated .in Figures The advantages ofthe invention will be readily appa-rent to those skilled .in ltli-e'art to which itbe-longs. ,.iForlinstance, an im- "portantadvantage Aisr that a very 7compact 5 and 'inexpensive .stand or :rack vis provided, by means ofwhich a trough .may be rigidly supported in a :position to vperinit'oi'th'e convenientrassernblyof children around it for tooth brush drills. i It willalso be .observed 'that the stand Vis exceedingly simple-and in'- expensive kin construction,l and may be readily folded `and convenientlystored when notrequired.
