is provided between the bottom 'of the dam per 45fand the adjacent inner wall 46.

Y The members 44 and 51. are pivoted to each other and likewise to a link member52 at the point 53 for the purpose of actuatin a fresh air damper 54 connected to said and which will thereby open the fresh air tube 55 upon a rise of .the temperature within the tray and will also automatically close the saine upon the lowering ofthe temperature thereof, all of the same be' accomplished through the said thermostautli member and its connect-ing means. The said fresh air tube 55 alines with a passage or stub pipe 56 in the rear wall of the casing 25 5and feeds fresh air to a' point slightly removed from the center of the tray and beneath thewire bottom .37 thereof, it bein "noted that all of the-lever members as we `as the fresh air flue are positioned between thiswire bottom and the main bottom 36 A thereof.

The partial operation of the device having alread been described, the' complete workings ereof are believed to be now ap arent.

ith the superposed trays in any desired l 100 ition as shown in Fig. 4, an excessive rise in temperature within an intermediate tray will open the fresh-air inlet beneath the same and simultaneously -will also open both of the side hot air dampers forallowing the hot air within the tray to pass outwardly and upwardly to enter anyother tnry in which additional heat is nired a for which reason its respective side damper-s as well as its fresh air damper arel closed as shown in the upper tray in 4.

`While an outer 'cas' 25 or containing thetrays is desirable, it will be evident that any number f superposed trays mais; be-employed without such a casing but wit Amerely a top member positioned. upon the uppermost tray, a self-re lating separate tra system being contemp ated. f
