A
j Method of operation v It will be observed that the heat will rise from the heater 2O through the 4passageway 34 into' the traycompartment 5 between each scoop and its adjacent tray thro-ugh the bottom lof the tray'outv the top ,thereofl on the opposite side toY the point of itsentrance beneath the bottom of the next adjacent superimposed scoop and then pass upwardlywithout; circulating over thefother trays through the next opening 45, passageway 37 down, through the passageway 38 where it will be cooled by the pipes 41, through which outsideV air may be circulated drawing in any air through the damper 71 which maybe desired, vpassing to-the'passageway 36thence over the heater again into the new circuit. f It the heat on the' thermostat 46 is excessive, the damper 55 will open andthe air will pass out the passageA 39, pipe-21 over the heater and out the stack 19. Fresh lair beingk drawn in to coolthe'heater or'damper. f VIf it is desired, due' tothe heat, to provide automatically for the exit of air," the air will make its exit at the'top through'the openings 66 under the damper 65 controlled by the thermostat 59. Direct by-passing vof air maybe effected by the direct Control of the damper 69. Y, y f' The excessiveheat in the cabinet will cause -a shut-down of the heater bythe action of thesthermostat 26. Y
