This invention relates to an improved type of incubator embodying among other characteristics a heating apparatus adapted to keep the atmosphere at a constant temperature.

Another object of the invention contemplates'adelecting'ap aratus by means of which the heat may e evenly distributed within the bottom of the incubator.

An additional object of the invention comprehends fan members preferably located within the top of the' incubator to facilitat circulation of the atmosphere.

A cardinal object of the invention resides in the provision of racks and frames therefor to sustain eggs and by which the Asame may be tilted. Y Y A,

More specifically stated the racks are adapted for shiftingmovement to tilt theV frames therefor. p

With the above and other'objects in view, the invention further consists in the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims. l

,In the drawings Figure 1 is a vertical sectional view taken through the completed invention.

Figure 2 is a sectional view taken on line 2-2'of Figure 1.

Figure 3 is a vertical sectional view-taken on line 34-3 of Figure 1.

Referring to the drawings in detail, wherein likelcharacters of reference denote corresponding parts, the reference character 10 indicates a pit' sunk within the ground and havin communication with a floor surface 11. y oil burner or other heating device, such as indicated at 12, arranged within vthe bottom of the pit is'adapted for connection with a thermostat 13 through the instrumentality of a pipe line 14, the latter also being in communication with a fuel reservoir 15 which may be arranged for convenient reiilling. An overiiow pipe 15 is in communicationwith the oil burner whereby excess-oil within the pit will be carried oi instead of allowing the fumes therefrom to be` circulated within the incubator.

support receptacles 20 for water or other liquids which may be evaporated in conjunction with the heat, whereby the atmosphere will be humidied.

A deiiector 21, carried by and elevated from the iooring 11 immediately above the pit 10, ,is adapted to collect and deflect or otherwise spread the heat from the pit across the flooring. A

Fans 22, carried within the roof 17 and havin communication with inlet ports 23, are a apted to keep the humidiiied atmosphere circulating within the'l incubator due to the specific shape of the upper surface of the deflector upon the side and end portions thereof. Discharge port-s 24 located adjacent the ends and within the roof of the incubator housing are adapted to provide the means toA facilitate emission of foul air.

The air currents from the fans directed upon the inclined surfaces or facets of the deiiector will cause the heated or humidiiied air .to be sucked or otherwise drawn outwardly from under the edges of the delector and directed upwardly for contact with the eggs within the trays.

A vent pipe 25, extended from the heating element 12, is projected through both the deflecting dome 21 and roof 17, whereby the gases may be taken off from the heating element.

the humidity created in the evaporation of the l liquid within the receptacle,pby said heat,

will producethe desired atmosphere for the purposes of incubation.

Standards 28, supported upon the flooring 11 at the ends of the incubator and having connection at the uppermost ends with the undersides ofthe roof 17, are arranged in spaced parallel relation upon the opposite sides of an aisle within the housing. Access may be had to one end of the housing by one ofthe doors 18, inasmuch as the heat deiector 2l extends above the floor and is arran ed' in the path of movement through sai aisle. For this purpose, other doors are provided within the sides of the housing to facilitate access to racks and trays therefor, he descriptions of which will presently fol- Racks 29, preferably of angle bar construction and in the nature of elongated frames, substantially as illustrated in Figure 2 of the drawings, are tiltably mounted at inter- -me'diate points in their lengths upon rod of the drawings, the lowermost ends of the supporting bars 31 and 32 are elevated from the lioor surface 11 but when it is desired to tilt the racks 29 and trays 34 supported thereby, it is therefore necessary to remove bolt members 35 from locking arms.36 horizontall disposed adjacent the lowerinost ends o the standards 28 and the supporting bars 31 and 32 will engage the upper surface lof the iiooring 11 as illustrated in dotted lines to the left in Figure 3 of the drawings.

The bolts 35 are also passed through the lowermost ends of the 'supporting bars 31. .Removal of said bolts will permit tilting of the racks and trays to occupy either ofthe extreme positions,` as illustrated b the dotted lines in Fig-ure 3 of the drawings. Such movement is necessary at prescribed interf l vals to facilitate proper incubation of eggs. Such action will valso causey the eggs to partially turn whereby other sides of the eggs may be heated.

The trays and stationary. Said stationary frames are utilized for the supporting of chicks alread hatched. The chicks after breaking throng the shells upon the tilting trays 34 are then transferred to the trays upon the stationary frames; the latter having reticulated bottoms, whebym'ore air will circulate around I the chicks to dry them olf.

vThe invention is susceptible of various Vwithin the housing, and

frames, located adjacent the ends of the turning or tilting trays 34, are A fall .within the scope of the appended claims.

- Having thus described the mvention, what is claimed is y1. In an incubator, a housing having a pit,

a heating element arranged within the pit,

moisteners for the air emitted from-said pit', a deiiector having inclined surfaces and eX- tended over the pit and elevated from the bottom of the housing, `egg trays arranged an members directing air currents upon the inclined surfaces of the delector to cause circulation of the generated air around and aboutsaid trays.

2. In an incubator, a housing having a pit,

* a heating element arranged within the pit,

moisteners for the air emitted from the pit humidifving the quality thereof, a deflector arrange in spaced relation from the bottom of the housing over the pit having inclined upper surfaces, egg trays arranged within the housing upon opposite sides of the inclined surfaces of the deflector, and fan members arranged within the top of the housing above the trays for directing air currents upon the inclined surfaces of the deflector to create suction of the heated airbeneath the deflecto'r and circulate same around and about said trays. l

3. In an incubator, a housing having a pit, a heating element arranged within the pit, moisteners for the air emitted from the pit humidifying the quality thereof, a deiiector arranged in spaced relation from the bottom of the housing over the pit having inclined upper surfaces, egg trays arranged within the housing upon opposite side of the inclined surfaces of the deiiector, fan members arranged within the top of the housing above the trays for directing air currents upon the inclined surfaces of the 'deflector to create suction of the heated air beneath the deilector and circulate same around and about said trays, and said trays being tiltably
