ALEXANDEBJOHN WHITE, OF HERTFORD, ENGLAND.

Application filed January 15, 1924 Serial No. 686,247.

To all whom it may concern:

Be it known that I, ALEXANDER JOHN Vl I-IITE, a subject of the 'King of Great Britain, and resident of Hertford, England, have invented certain new and useful Improvements in Incubators, of which the .following is a specification.

The objectsof thepresent invention are to provide simple meanswhereby the capacity of an incubator can be readily increased to accommodate an increased number of eggs, to provide improved means whereby the several compartments containing the eggs may be readily maintained at a suitable temperature themanipulation of such means being eifected from the exterior of each compartment and furthermore to preserve a cool base to the tray containing the eggs to be hatched.

ith these objects in View according to my present invention, Iso construct a number of elements each containing removable trays for the reception of the eggs, that any number of such according to the capacity of incubator required maybe superimposed upon one another, forming what may be termed an expanding incubator, eachof said elements being provided with-hollow walls that form means, when the elements are superimposed, for conveying the heated air upwardly from the heating chamber in the base beneath the lowest element,'and each element carrying dampers for passing a regulatable quantity of heated air into each compartment and over the eggs 011 the tray therein; moreover each of said elements is so formed that there is an air space he neath each tray that communicates with the outer atmosphere by an opening provided in front of each element, so as to preserve a cool base to the tray containing the eggs to be hatched.

In order that my invention may be clearly understood reference may now be had to the accompanying drawings in which:

Figure 1 is a view in part section and part front elevation and Figure 2 a sectional plan of one of the four similar parts of each incubator element.

Figure 3 is an elevation of a built up in cubator, the base and one of the lower compartments being shown in section.

Figure 4 is a plan view of Figure 3, the right hand compartment and the base being in section.

Similarfreference characters relate to like parts in all thefigures ofthe drawings.

It will beobserved that according to the construction illustrated each of the elements isof rectangular form and comprises two front and two back compartments, any number of such elements 1, 2, 3, a and 5 being placed one above the other to formthe incubator as shewn in Figure 3. l/Vithin each of the aforesaid compartments: is slidably mounted a tray a in which the eggs to be hatched may be placed and each of the elements '1, 2, 3 is constructed with h0llow walls 5 each of the' inner memberso of thesame beingprovided with asliding damper d on the rear of which are provided the racks e that engage the small pinions mounted on the spindles 9 that extend through the frontiiand rear-of the framework and are provided with handles or knobs ft for their manipulation.

The front of each compartment of the elements 1, 2, 3 is provided with an ordinary hinged glazed door 2' and beneath each tray a is provided an air space j which is'in communication withthe outer atmosphere by the openingrlc provided inthe front of each element. Above the doors 2' areprovided ventilating holes Z.

When any number of the elements de scribed above are superimposed to form an incubator of any desired capacity beneath the same is situated an air heating element 6 divided into four chambers m the admission of fresh air thereinto being regulated by any suitable means.

The chambers mare supported on the standards a and form a base for the elements l-5 aforesaid. Any convenient form of heating apparatus may be employed in connection with the chambers m and in the drawing are shown four ordinary oil lamps 0 each of which is provided with the well known regulating damper p and uptake g. In connection with each of the regulators p is provided circuitous fine pipe whereby the products of combustion from each of the lamps 0 are conveyed through the air heating chambers m and escape through the vent or uptake 9.

It will be obvious from what has been stated that the heated air from the respective chambers m of the air heating element or base 6 passes into the hollow walls 8 of the said element that register with the hollow walls Z) of the' superimposed elements 1, 2, 3, 4:, and 5 whereby the heated air passes into the said elements wherein are situated the trays a containing the eggs to be hatched the dampers cl manipulated by the handles it permitting of regulating the quantity of heated air admitted to the individual trays (1 according to the different stages of incubation existent,

The air spaces j and openings k preserve a cool base to the trays a that is essential for obtaining the best results and the ventilating holes Z permit the emission or escape of foul gases from within each of the compartments; these holes Z ensuring a continuous flow of heated air from the hollow side walls 6 into the several superimposed compartments of the elements 1-5.

It will be understood that although the apparatus illustrated and described is approximately square in form obviously the same may be constructed of any other suitable shape and according to the size and construction of the heating stove or other appliance there may be one heater employed instead of four as instanced with reference to the drawing although obviously by the use of the several heating stoves an advantage accrues by the practical isolation of each of the stacks of superimposed elements.

What I claim is 1. An incubator comprising the combination with a heating element divided into a plurality of chambers and provided with inner and outer walls constituting a space between said walls, heating means associated with each of said chambers, and means for conveying the products of combustion of said heating means through said chambers of a plurality of elements superimposed on said heating element each of said superimposed elements comprising a pinrality of compartments and a plurality of trays each of said trays being removably and slidably mounted Within each of said compartments and each of said superimposed elements being provided with inner and outer Walls constituting a space between said walls that register with the space between the inner, and outer walls of the heating element, slidable dampers mounted on said inner walls and controlling the supply of heated air from the aforesaid spaces into each compartment and means for operating said dampers.

2. An incubator comprising the combination with a heating element divided into a plurality of chambers and provided with inner and outer walls constituting a space between said walls, heating means associated with each of said chambers, and means for conveying the products of combustion of said heating means through said chambers of a plurality of elements superimposed on said heating element each of said superimposed elements comprising a pinrality of compartments and a plurality of trays each of said trays being removably and slidably mounted within each of said compartments and each of said superimposed elements being providedwith inner and outer walls constituting a space between said walls that register with the space between the inner and outer walls of the heating element, slidable dampers mounted on said inner Walls and controlling the sup ply of heated air from the aforesaid spaces into each compartment, means :t'or'operating said dampers, and means for conveying cool air to the bottom of each of said trays.

In testimony whereof I atiix my signature.

ALEXANDER JOHN WHITE.
