INCUBATOR.
SPECIFICATION forming part of LettersPat-ent No. 660.309, dated october 2s, 1900. Application filed January 4.1900. Serial No. 359. (No model.)
To ctZZ whom it may concern:
Be it known thatI, OLIVER W. RANDOLPH, a citizen of the United States, residing at Mc- Clure, in the county of Henry and State of Ohio, have invented a new and useful Incubator, of which the followingis a specification.
This invention relates to incubators; and one of the principal objects of the invention is to provide in connection with an incubator-body means for discharging fresh air in a heated and moistened condition into the in' terior of the incubator and Ydistributing or spreading the same from above the egg-tray and over the eggs.
Another object of the invention is to provide efficient means for properlyand thoroughly Ventilating the incubator and freeing the same from foul air.
Another object is to provide a novel form of egg-tray in connection with an egg-separating frame by means of which the eggs are' prevented from coming in contact with each other, the construction at the same time enabling the eggs to be rolled or partially turned over at proper intervals.
The invention also has for its object to pro-y vide a novel form of nursery-tray comprising a flexible or fabric bottom and having means whereby the said flexible bottom may be readily and quickly removed and replaced by another piece of fabric. E
The invention also contemplates novel means for conveying the Water after it has cooled in the main tank back to the boiler or heater, so that it may be reheated and .conveyed in the form of moisture back to the interior'of the incubator.
Otherobjects and advantages of theinvention will appearin the course of the ensuing description.
The invention cons istsin an incubator embodying certain novel features of construction andarrangement of parts, as hereinafter fully described, illustrated in the drawings, and incorporated in the claims.
In the accompanying drawings, Figure l is a vertical sectional Viewv of an incubator constructed in accordance with the present invention.. Fig. 2 is a similar section taken at right angles to Fig. 1. Fig. 3 is a broken perspective view of the hot-Water tank, showing also the boiler or heater, the mixing-chamber, and the connections between said parts.
Fig. 4 is an enlarged vertical section through the heater. 5 is a similar view taken through the mixing-chamber. Fig. 6 is a detray and egg-separating frame, showing said parts properly associated. Fig. 7 is a fragmentary sectional perspective View of the nursery-tray.

Arranged in the upper portion of the incubator is a hot-water tank 9, closed on all sides, top and bottom. This tank is preferably shal- The outer door is hinged at its low in order to economize space, but extends entirely over the egg-tray hereinafter described. Mounted upon the outside ot' the incubator-body is a double boiler or heater comprising a lower or main section 10 and au upper section l1, the two sections being connected by the heateror boiler tubes l2. Arranged at one side of and'adjacent to the heater is a mixing-chamber 13, having at its lower end a fresh-air-inlet pipe r14 and at a point intermediate its ends a steam-supply pipe l5, which communicates with the upper end of the upper section 11 of the double heater, said steam-su pply pipe being provided at a point intermediate its ends with a cut-off valve 16 in order to shut off the supplyof hot air or steam when it is desired to ventilate the incubator. Adjacent to its upper heater.

end the mixingchamber has connectedthereto a moist-ener-tube `17, which extends `horizontally beneath the hot-water tank 9 and is secured thereto for support by any suitable. or convenient means. The moistener-tube 17 extends entirely acrossthebottom ofthehot-L water tank and is provided with a right-an* gular upward extension or vent-pipe 1S,which passes through the upper and lower walls ofi the hot-water tank and projects suiciently above the tank to receive a stopperlQ, which is inserted therein when the apparatus `isa` used for supplying moist air to the interior of the incubator. In operation the steam or hot air passes from the heater through the steam-supply pipe 15 intothe mixingechamber 13 and upward tolthennisteneitube 17,
1thus drawing fresh airup through theair-` tube 14 and carryinga suiiieient'quantity'of fresh air with it `to the interiorof `the incubaton `moistener-tube in close proximity totheegg-` tray.
The double heater or boiler comprises inits `lower section an outer cylindricalwall 21 and an inner flue-Wall 22, which is of conioocylindrical shape, tapering `graduallyfromits lower end, which is the`larger,`toward lits" upper end, `thusforming` anupwardly-'con tracting fluefor the products of combustiomfrom a suitable vburner 23, arranged Abeneath the The due-wall 22 `and outer wall `2l are sealed at top and bottom ibyth'elupper `and lower walls 23 aud24, respectively, -so as to form an annular \vaterspace 25.

thereby equalizing the temperature of the waterwvithin the tank.
The lower section of the boiler is provided near its bottom with an extension 32, from which branch pipes 33 diverge upwardly and enter thehot-water tank at that side or end adjacent the heater. The water within the tank 9 as it cools passes outward therefrom through the return water-tubes 33 and is collected in the heater extension 32, whence it passes into the heater and is reheated. In :this way acomplete circulationis established between the hot-water tank and the heater. Thehot-watertank is provided with a Vertical regulator-tube 34, through which may freely pass one of the operative parts of an lordinary thermostatic regulator, and the heater is'providedwith a dra`woff cock 35 in ordertoprovideifor emptying the waterfrom itheiheaterwhem 1the incuhatorfis not in use.

By ithe construction 'above described ithe retaining-strips may be quiekly'remo'ved and the 'fabricbottom taken out of the `nurserytray `'and `clermedor replaced by anew bottom.
By reference to Fig. 7 of the -drawings it `will besee'n that'when "it is desired Vto insert a newiiexiblebottom 40 Ait fissirnplyneces- 'sary to kpull 4'upwardly upon fthe edge of the fabric protrudingifroni under fthe'outer edge of each retainingLstrip. `Thestrip will inthis zmanner be tilted'slightly and will effect the nseparation ofthe contiguous'inclined flanges 39and 42 and Willpermit the-removal ofthe l"fabric bottom.

Between the hot-'water tank and thc nur` The frame of this tray is ofpopen rectangular; form, each of the side and end bars thereof;` being L-shaped in cross-section, as shown at: 44, so as to form an upright surrounding rim sery-tray is interposed the egg-tray43.
and inwardly-extending horizontal ledges 45.
Upon the ledges 45 are placed egg-troughs;
46, preferablyformed of sheet metal and provided with upturned and upwardly-diven ging or flaring longitudinal flanges 47, be-` tween which the eggs are confined. The upper edges of the flanges 47 lie in the same horizontal plane and form rests for an eggseparating and rolling frame 48, which is composed of a parallel series of strips or division-pieces 49, intersecting or extendingat between the flanges 47 thereof, and thus it is impossible for the eggs to come in Contact with each other.
The egg-separating frame 48 is sufficiently smaller than the egg-tray'43 to admit of said egg-separating frame vbeing moved bodily, thereby adapting it to act upon the eggs so as to roll or turn the eggs partially over at the proper periods. The egg separating frame is not attached in any way to the eggtray, and therefore when the hatching-out process begins the said egg-separating frame maybe removed from the egg-tray and, if desired, withdrawn from the incubator. Before doing so, however, it may be desirable to roll the eggs laterally from the troughs 46 into the spaces between the troughs, so that the eggs will rest on the adjacent edges of parallel troughs. By this arrangement the chickens as they hatch may drop through the space between the troughs and fall upon the flexible bottom of the nursery-tray beneath.
In ord er to ventilate the incubator, the cutoff valve 16 may be closed and the stopper 19 This will allow the bad air within the incubator to pass upward through the nozzles 20 into the moistener-tube 17 and thence outward through the vent-pipe 18, or steam may be allowed to pass through the moistener-tube 17, whereupon it will act by suction to draw the air from the incubator and force it outward through the vent-pipe 18, at the same t-ime drawing inward fresh air through the air-pipe 14 and the holes 14u in the end of the body or casing, said air-inlet holes 14iL being shown by Fig. 2. It will thus be seen that I have provided a simple means for introducing moistened air into the incubator for Ventilating the incubator and freeingthe same from bad air and The rear edges of the sl ripsy water between the heater or boiler and the hot-water tank. It will also be seen that l have provided an egg-tray in which the eggs may be easily turned partially over and by means of which the chickens as they hatch may drop through the egg-tray upon the nursery-tray beneath. It will also be seen that the mirsery-tra57 is provided with a removable exiblebottom and that such bottom may be quickly removed and replaced whenever necessary.
From the foregoing it. is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be linderstood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing front the spirit or sacrificing any of' the advantages of the invention. l
