ST'ES TRAY FOR INCUBATORS AND BROODERS.

Application led February 3, 1921. Serial No. 442,125.

y To all whom t may concern.'

` that is provided with means for providing an even heat so that the eggs or chickens carried thereby will notbecome chilled under ordinary conditions.

Another obj ect of the invention is the construction of a tray which gathers and retains heat so that the chickens or eggs carried thereby will not readily become chilled, which means is also pro-vided for preventing overheating the eggs or chickens.

With these and other objects in View, my invention comprises certain novel combinations, constructions and arrangements of parts `as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claim.v i

In the drawings:

Figure 1 is a top plan view of an incuhater constructed' in accordance with the present invention.

Figure 2 is a View in side elevation of the incubator.

Figure 3 is a sectional view, taken on line 33, Fig. 1, and looking in the direction of the arrows.

Figure 4 is an end view, in elevation, of the incubator, looking at the end to which the heating apparatus is connected.

Figure 5 is a sectional View, taken on line 5-5, Fig. 3, and looking in the direction of the arrows.

Figure 6 is an enlarged fragmentary sectional view, taken on line 6 6, Fig. 1, and looking in the direction of the arrows.

Referring to the drawings by numerals, 1 designates the body of the incubator, and 2 are the legs supporting they same. The body has an inner lining 3 spaced therefrom between which inner lining and the outer lining a compartment 4 is formed that may contain hot air but preferably is for hot water.

The heating apparatus comprises a tank 5, into the central part of which extends the chimney 6 of the lamp 7, and the tank 5 is connected by tube 8 to the top of the body 1 and by the curved tube 9 to the body nearv its bottoni; these tubes 8 and 9 provide means for permitting water in the tank and body of the incubator to circulate, while heated by the lamp 7.

A cap 10 is provided for iilling the compartment 4.

A. hollow hinged door 11- is formedupon the top. The front door 15 is hingedy upon the body 1 of the incubator and this door' has glass in the same as usual, so that eggs can be easily seen upon the tray 16. The young chicks can also be seen through the front door 15. y l' The tray `16 rests upon angular brackets 17, each bracket `being provided with a horizontal foot 18. y

The tray 16 comprises a false bottom. 19, in which bottom vis compartment. 20, the compartment being Vi'illed by a liquid 0r water by the removal` of the cap 21. A. strip of feltv 22 Vis placed upon the false bottom and the uppery section 23 of `the tray, containing' the eggs 24, is placed upon the felt 22; the false bottom, :telt `and upper section or container 23 can be securely fastened'together by any suitablev means. `The felt 22 prevents too much heat-'affecting the eggs 24 and by reason of the closed bottom of the tray air is kept from rushing up through the bottom and by the eggs, which would tend to unnecessarily cool them or harden the shell during incubation.

lt will be obvious that young chickens can remain on the tray 16, without injury, until the operator removes same by opening the door 15.

The means for controlling the temperature of the incubator comprises a coil thermostat 25 mounted upon lug 26 attached to the inner wall of the incubator, Fig. 6. The outer loo-p or coil of the thermostat terminates in a vertical rod 27, which rod extends through the pipe 28 and above the top of the incubator, or broeder, as this thermostat and damper device is applicable to both the incubator and the broeder. The extended upper end of the rod 27 is threaded and upon this threaded end are a pair of nuts 29. Between these nuts 29 are the 10013 ends 30 of the flame cut-orf lever 31 and the damper lever 32. The levers 3l and 32 are pivotally mounted in the notched upper ends or angle brackets 33. The damper lever is connected, at its upper end, to the damper 34, which damper 34 closes the heat compartment 35 ot the tank 5.

The flame cut-ofi' lever 31 is provided with a vertical extension 36, Which extension 36 pivotally connected, at its lower end, to arm 37 of the rocking frame 38, which franie is of an open structure being formed of. Wire; the frame 38 is adapted to straddle or move over the Wick 39` of the lamp 7 and cut out or extinguish the flame, as shown byfdotted lines 40 in Fig. 3, when the temperature becomes too great in the incubator', causing the expansion of the thermQSf-af: 35 and the Shevna upV the rod 37, thereby permitting the levers 3l and 32, at their outer ends, to move downwardly, causing the closing of the damper 34 and the swinging of the rocking frame 38 to cut off or put out the 39. This will result inthe stopping of the heating of the liquid in the tank,` but by reason of the damper 34 bein-g closed, the heat in the tank Will only slowly be given off, thereby retaining the heat in the Whole apparatus a very long time suliicient to allowr the operator to discover that the li ht is `out or extin* gushed., 011 @limit the .lighting Of the lamp before any arm has been done.

fAs Vhereinbleiifore indicated, my incubator @an be `@asili adapted .t0 the use Of a broodel', by the Chickens remaining @n the tray 16, or by placing in any suitable` floor o n the bracket 1.7 to keepi the chickens olf the inner (lining 3. I make no claim to the iviooring that would entirely the space and prevent the chickensfrom dropping ont@ the lining '3, but this eerine can be easily inserted in the body j., Withoutin volving invention.

The pipe 4l extends through the side. of the body l, its inner end projecting into the inner compartment of the body and its outer end extending beyond the outer surface of the body, so that the outer atmosphere Will enter the compartment, containing eggs or chicks, allowing the right degrec of moisture or a similar quantity of ire-sh air to enter the chamber and thereby keeping the conditions in the chamber sanitary, the air being purified by the medium of the pipe 41.

While I have described the preterred structure of my apparatus,`an d have illus Hated-"Phe Sain@ in the aeomraeyes dawi-y IleS, @erta-n minor Changes or ltelibens en be by one eine@ in the @e to which this invention relates., .in the manufacture of my apparatus on an enlarged scale and I, therefore, reserve the right to make such alterations or changes as shall.
