Application filed October 7, 1910. Serial No. 585,753.

To all whom t may concern Be it known that I, CHARLES E. BoNINF., of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Incubators, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to incubators for tile artiticial hatching of eggs, in which ,meal s for maintaining a carefully regulated temperature are provided for a series of incubator compartments, each compartment ha.v. ing suitable trays for the support of eggs at varying distances from the heating means.

The invention relates more particularly to the arrangement and construction of t-he compartments with relation to a unitary heating system applied to the entire series of compartments, and also to the means for moving and adjusting the trays in each compartment.

An incubator embodying my invention is shown in the accompanying drawings, in which-Figure I, is a side elevation of the incubator. Fig. II, is a longitudinal section of the same. Fig. III, is a cross section of the same alon the line III, III, of Il'ig. I. Fig. IV, is a etailed sectional view of a part of the bottom of one ot'the incubator compartments showing the means for regulating the height of the egg tray.

The incubator compartments 1, of the incubator. are arranged in parallel rows mounted a suihcient distance from the floor of the incubator house on legs 2, 2. In this way each compartment may be provided with a hinged door 3, and at the same time the whole series are conveniently heated by a single heating system.

At one end of the incubator is a *special` compartment 5, containing two interlock-- ing manifolds 6, 6, communicating at their ends respectively onefwith a pipe 7, for the feeding of hot water, and the other with a pipe 8, for the return of cold water to the heating apparatus 9. This heating apparatus will not be here described since .it

across the entire top of the incubator and a number of them traverse each compartment until they reach the other end of the incubator, where there is provided a special compartment 12, containing the header 13, with which all of the. pipes communicate. In this way hot water from the manifold 6, is led by every other pipe of the series to the header 13, and returned by the alternate pipes, so that the distribution of the heat in the horizontal series is evenly leii'ected across the entire space of each incubator compartment as traversed by they pipes. The heating pipes are supported near the top ofeach compartment, which in conjunction with suit-ably arranged openings in the walls of the compartments, cause the warm air to be circulated over and around the eggs.

Within each compartment there is supported an egg tray 15, consistin of a suitable frame with an open or latticed bottomv coveredy with wire mesh, above which the edges rise sufficiently to hold a layerof eggs resting on the bot-tom. 'To the bottom of the tray is secured a supporting frame 16, mounted on a vertical arm 17, slidably mounted in a supporting bracket 18. A rack 19, formed upon one edge of this arm is in engagement with va pinion 20, fixed on a shaft 21, which carries at Aits forward eX- tremity a crown wheel 22, with teeth in engagement with the crown 23, conveniently formed upon the casting which forms the bearing for the shaft 21. rIhe crown wheel and crown are normally kept in engagement by means of Ithe compression ot a spring 25, interposed between the pinion 20, and the adjacent bearing of the shaft, but by manipulating the crown wheel 22, the shaft may be drawn against the pressure of this spring so as to disengage 'the crown wheel from its crown, permitting the turning of the shaft, so that the pinion by engagement with the rack on the arm 17, may raise or lower each egg tray the desired distance. When this has been done, the reengagement of the crown wheel `with, its crown immediately takes place, so that the tray is supporte at the desired height. rIhis arrangement is a very convenient one because it is necessary to alter from day to day the distance between the heating pipes and the egg trays. By the Ameans which I without otherwise opening the incubator compartment; and as the aperture through Which the arm 17', passes down through the bottom of the compartment is a tight one, there is no loss of atmosphere Within the incubator compartment attendant upon the adjustment of the tray.

Having thus described my invent-ion, l claim l. In an incubator, an' incubating coinpartment, an egg tray, and means for supporting the same including a vertical arm passing through the bottom of the compartment, and means for moving and setting the arm at any desired position, Without opening the compartment, said means including a rack on the arm, a longitudinally movable shaft carrying a pinion engaging therack, and a spring acting on the shatt for moving it longitudinally to hold it in locked position against a stationary part of the apparatus.

noaaoia 2. ln an incubator comprising incubating compartments with heating pipes at the top thereof, and an egg tray Within each compartment supported upon a single vertical arm projecting through the bottom of the compartment, means for moving and setting the arm at any desired distance from the heating pipes in the compartment, Without opening the same, said means including a rack on the vertical arm, a shaft carrying a pinion en aging said rack, a crown Wheel on said sha t, a crown normally engaged byl the crown Wheel, and a spring'controlling the shaft to cause such engagement.

ln testimony whereof, l have hereunto signed my name, at Philadelphia, Pennsylvania, this sixth day of Catcher, 1910.
