thereby making it possibleto employ horizontal egg trays. In all incubators of this class it has heretofore been necessary toemploy a tray inclined from the sides toward the center, and this, to some extent, had the effect of producing a fairly even heat to all the eggs, although, it is obvious, the eggs would press toward the center of the tray and this causes no little inconvenience. In my invention it has been mypurpose to eliminate this great inconvenience and at the same time assure a much greater degree of accuracy in uniformly heating the eggs on the tray.

My invention consists of certain details of construction, hereinafter set forth, .pointed out in my claims, and illustrated in the accompanying drawings, in which Figure I shows a perspective'view of my device, the cover being in raised position; v c

' Fig. II shows a detail view partially in section, of a part of the central heating plant I employ;

and

Fig. IV shows a detail view partiallyin section, of a modified form of apart of the heating plant I employ. y

Referring to the accompanying drawing, the reference numeral 10 is used to indi cate the body of the incubator and the numeral 11, the cover which is hinged thereto. Below the body of the incubator I have secured an oil retainer 12, provided with a lamp 13 which is located immediately beneath the center of the incubator. The said lamp is provided with a metal chimney 14:, which extends upwardly a slight distance through the base of the hotly portion of the inenhater. numeral 113 indicates a Specification of 'Letters Patent.

metal drum, having two walls,- parallel and spaced apart, said drum being secured in the base of the body portion of the inciibator and extending upwardly therefrom on a slightly inwardly tapering incline. The numeral 16 indicates a hollow distributing head which is centrally secured in the cover 11, and is designed to fit over the inner wall of the open end of the drum 15, when the cover is in closed position with relation to the body of'the incubator. The head 16 is provided with four hollow pipes, 17 radiating therefrom, one extending to each corner of the cover where it is connected with an orifice which leads outwardly through the cover.

The drum 15 is surrounded by a second drum 18, provided with vertical sides and with an open top, said drum also being provided with lugs 19, placed on a horizontal plane surrounding said drum and designed to receive an egg tray 20, said egg tray being provided with an orifice or an opening, designed to fit over the said drum 18. Said drum 18 is also provided with a plurality of orifices 21, located beneath the line of the egg tray 20 and designed to permit air to enter the base of the drum for purposes hereinafter set forth.

Surrounding the drum 18, I have provided a circular water receptacle 22, its lower end being designed to rest upon the tray 20, and its upper end being open, as shown. Surrounding said water receptacle is a drum 23, also resting upon the egg tray 20, said drum being provided with a plurality of orifices 24, formed by a semi-circular cut in the drum, the portion of the drum inside said out being turned inwardly so as to form lugs 25, designed to engage the outer su face of the water-receptacle 22, thereby spacing the drum 23 uniformly around the water-receptacle 22. The numeral 26 indicates a drum, open at its base, surrounding an tray which is supported by the body 10, the central portion of the tray resting upon the lugs 19. The lugs 19 are on a horizontal plane with the securing means for the frame of the tray, and the said tray is horizontal on its upper surface.

In practical operation the heat from the lamp 13 passes upwardly through the metal chimney 14L into the drum 15. The drum 15 being heated, radiates heat outwardly to the drum 18 and also heats the water-receptacle 22. The direct heat from the lamp passes outwardly to the center of the t'ay through these drums, and the exhaust heat passes through the head 16 and the pipes 17 and their respective orifices in the cover, to the outer air.

If this system of heating were all that could be provided for the incubator, it would be necessary to have the egg tray dipped toward the center, for the reason that the heat would not be uniform and all of the eggs would not be heated to a like degree. it has always been necessary in centrally heated in cubators to incline the trays in this manner so that some degree of uniformity could be secured for the heating of the eggs. in my invention T have provided an auxiliary heat which I deliver to the four corners of the incubator, thus providing five different points for the heat, and a uniformity of heat is secured thereby. The auxiliary heat consists of the heat in the drum 18 passing upwardly through the drums 26 and the pipes 27 to the four outlets, as hereinbefore set forth.

The object of using the water receptacle 22 is to provide a moist heat and this moist heat is also divided so that the same is delivered centrally and also to the four corners of the incubator. The moist heat is circulated in the following manner; the drum 26 extends downwardly into the water receptacle 22, the end of the drum 26 entering the water. This completely seals and divides the water-receptacle and the moist heat inside of the drum 26 passes upwardly and outwardly through the delivery pipes 27 and is delivered into the four corners of the incubator.

The moist heat outside of the drum 26 rises upwardly and is delivered through the top of the water receptacle 22, thereby providing a central delivery fr. a portion of the moist heat.

It is necessary to have the openings 21 provided in the manner shown, in order to secure a perfect circulation of the heat, and while I do not desire to be limited to a device of this character, having said openings, yet I do desire to claim it in this way.

In the modified form shown in Fig. IV, I do not use the water-receptacle, but I simply divide the indirect heat from the lamp without regard to any moisture that might be desired to be mixed therewith.

Otherwise the modified form is in exact conformity to the main invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. In an incubator, a body having an egg chamber and a cover therefor, an air drum arranged in the egg chamber open at its top, a second drum concentrically arranged about the first drum, a chimney extending upwardly through and above the first drum, a head carried by the cover for removably seating over the chimney, conducting pipes connected with the head, and a heat distributing drum encircling the head and ar ranged on the cover to enter between the concentric drums of the egg chamber.

2. An incubator comprising a body portion and a cover hinged thereon; a horizontal egg tray; a lamp mounted below the body of the incubator and extending upwardly theretln'ough; a metal chimney on said lamp extending through the orifice in the egg tray and nearly to the inner surface of the cover; a drum surrounding said lamp chimney, said drum being open at its upper end, a second drum also open at its upper end, surrounding the aforesaid drum; a water receptacle open at its upper end surrounding said second drum, said water receptacle resting on the egg tray; a hollow head engaging the top of the chimney and pipes running from the said hollow head to the four corners of the incubator and orifices therein to permit the heat and fumes to be expelled through the cover of the incubator; a drum, open at its lower end, secured to the top of the incubator and surrounding the aforesaid hollow head, the open lower end of the said drum entering into the circular water receptacle; pipes extending from said drum, one pipe surrounding each of the pipes connected to the aforesaid hollow head, said pipes extending to the four corners of the incubator and being open at their ends, substantially as shown and described.
