The stove is of any ordinary type ployed with apparatus of the kinds heretofore walls and the floor.

used, there are periods for instance when the temperature outside remains the same for considerable lengths of time, when there is almost no fresh air supplied to the room. Where my device is employed, I find it easier to maintain an even temperature and also to maintain a constant flow of air through the brooder room. Owing to the fact that thetwo thermostats are set for different temperatures, there is a constant changing of the damper position and'of the heat control. When the room gets too hot, the stove thermostat shuts off the heat. and the ventilator opens the damper (assuming the ventilator thermostat to be set two degrees below the stove thermostat) The air continues to pass out of the ventilator so that the proper temperature is' reached in a very short time. The room does not continue to heat up as long as where some othersystem might be used. r v

. On the other hand, when the outside tempera? ture cools off suddenly;-the ventilator thermostat at oncecloses the damper; so that the flow of air' into the building and out of it is reduced, and

if the temperaturein the room continues to'low'er, then the stove thermostat operates to glve greater heat. If the temperature remains about the'same for a considerable-lengthbftime,.then the are.

rangement of the thermostats at different temperatures will insure constant flow of air,"because the damper will not be fully closed when the stove is heating to'the proper. temperature.

The difference in the setting 'of "the thermostats will tend to cause either the stove or the ventilator'to'vary the temperaturein the room from the normal desired, but this tendencyisso slight that the ultimate result istomaintain an evener temperature possible.

The result is contributedto'b'y the fact that the air comes in at avariety of places. r I find that in a'house'of this kind, the air comes in at the endswhere the joints are formed between the sides and'the tops of the end walls with the roof and at the joints between the end I findthat, however well the buildings may be constructed, there is an ample supply of fresh air supplied at the joints and this affords an evener supply of air around the building, than is possible where window or door or intake shaft is used for supplying fresh air.

I preferably provide a fresh air inlet duct 40, extending through the wall *belowthe ventilating shaft 2 I and extending to a point below the pipe [9V and communicating with an upright pipe 4|, which surrounds the pipe l9 so that the air brought in through'the duct 40 will be warmed before being discharged into the ;room. Flow of air through the duct 40 is controlled by a slid ing damper 42 which is'operatively connected than; would otherwise he tilation.

ferent temperature from the to provide for the intake of fresh air through a number of small passages, which are separated around the curve of the roof, so that the air will come in at a number of openings in a small quantity at each opening.

V In Figure 6, I have illustrated a part of this construction. Iprovide a curved rafter 34a, which fits snugly under the roof 35, which is covered by the prepared roofing 36. Spaced from the rafter 3411a short distance is another curved rafter 39 to which the end wall 31 is fastened. Some air enters between the upper edges of the rafter 39 and wall 30, and the roof. The roof projects over the front wall 31 a trifle, for instance about an eighth of an inch. A curved cornice board 38 is fastened to the projecting end of the roof 35 and thus affords an air intake space between it and the wall 31. The wall 31 and the rafters 39 and 34a are preferably fastened together by bolts 35a. The heads 36a of these bolts serveas' spacers forthe cornice boards. On :the' bolts 35a between the rafters 34a and 39 are spaced washers 31a.

'I'msconstructionis not'intended for supplying sufficient ventilation in hot weather when .the windows or doors can be opened, but in cold weather it' provides for an ample supply of fresh air evenly distributed around the roof at both air for'the chicks over the entire floor.

- It will,.of course, be understood that the material employed in building the house may be such as is available and desirable. However, I preferably use sheet metal for the ventilator shaftll, because it is such a good conductor of heat, and I find that the use of the sheet metal tends to create a draft upwardly which contributes to the maintenance of continuousven- ,Changes'may be made in the details of the construction and arrangement of the parts of my improved sanitary building structure without departing from the essential features and purposes of my invention, and it is my intention to cover by my claims any modified forms of structure or use, of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention: f Y In a structure of the kind described, a room, a

ventilator shaft therein for taking air from a point near but, above the floor of the room and discharging it from the room, a heater in the room spaced from said shaft, a pipe surrounding theheater anddischarging above it, an intake air duct extending from below the shaft to the pipe, dampers in the shaft and the duct, a thermostat, in the room, operatively connected with the dampers for opening both at the same time, when the room temperature falls below a predetermined point, and a thermostat in the room for controlling the heater set fora slightly difsetting of the first thermostat. 7 H g JOSEPH T.
