INCUBATO R.

SPECIFICATION forming part of Letters Patent No. 735,885, dated'August 11, 1903.

Application filed April 23, 1903- will enable others skilled in the art to which it appertains to make and use thesanie.

This invention relates to improvements in incubators.

The object of the invention is to construct. an incubator in which an even distribution.

of the heat and a perfect ventilation is provided for.

A further object is to provide an incubator which will be simple in construction and operation, comparatively inexpensive of production, and the arrangement and operation of the parts being such as to closely simulate the natural method of egg-hatching.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims. 1

Figure 1 is alongitudinal vertical sectional View of the incubator. Fig. 2 is a vertical cross-sectional view. Fig. 3 is a horizontal sectional view of the same. Fig. iis a detail side elevation of the outside heat-flues. Fig. 5 is a detail View of the egg-tray.

In the drawings, 1 denotes the body of the incubatorcomprising an outer wall or casing 2 and an inner wall 3, spaced apart on all sides -except the bottom to form a dead-air compartment 3, which entirely surrounds the inner wall except at the bottom, as stated, and at the lower portion of one end of the casing, as hereinafter described.

4: denotes the egg-tray, arranged near the bottom of the incubator and supported upon cleats 5, fixed to the inner wall 3. In the con struction of the egg-tray an opeuframe 6 is provided, and to said frame is connected the edges of a coarse-wire screen 7, the screen being formed so as to slope on all sides toward the center to simulate the form of a hens nest.

Above the egg-tray and about midway be- Serial No. 154,011. (No model.)

tween the same and the top of'theincubator is arranged a frame 8, constructedto incline from the sides of the incubator toward the center in a substantially V form, and over said frame is stretched a covering of flannel or similar material forming a partition or diaphragm 9, the object of which is to hold the heat above the eggs in the tray and permitthe same to slowly passdownwardly through the flannel to the lower part of the incubator. After passing through the flannel diaphragm 9 the heated air is retarded in its further downward flow by the V-shaped" frame 8, which guides it toward the center,- from which as it passes downward it flows outwardly, so as to cover the entire area of the egg-tray 6. By the use of this retarder and deflector the heat passes downward and is spread to the several eggs on the tray in a natural manner and the natural process of incubation further simulated.

Below the egg-tray and near the bottom of the incubator is arranged a frame 10, covered with a fine-mesh wire-netting, forming a screen or diaphragm 12. The object of this screen is to retard the passage of the heat to the ventilators in the bottom ofthe incubator and prevent undue drafts.

13 denotes a ventilating-chamber arranged between the inner and outer walls at one end arranged upon the bottom of the incubator, one end of which communicates with the chamber 13 and the opposite ends of which open into the bottom of the egg-chamber of the incubator, as shown. ber 13 is out off by strips 13, arranged between the inner and outer walls 2 and 3 from the dead-air space 3 15 denotes a vent arranged. in the bottom of the incubator and is adapted to be closed by a plate 16, which is adapted to slide in ways 17, formed on a plate 18, having a hole formed therein, said plate beingfarranged upon the bottom of the incubator in such manner that the hole therein coincides with thevent-hole 15 in the bottom of the incubator.

19 denotes a heat-conducting flue arranged at one end of the incubator, near the upper end of which is formed alaterally-projecting branch pipe or flue 20, which is adapted to enof the incubator, and 14 denotes flues or pipes As shown, the said chamter the incubator above the flannel partition 9. Vithin the branch pipe 20 is arranged a horizontally-disposed plate 21., which extends partly across the flue 19, as shown. The plate 21 serves as a baffle-plate and causes a circulation or breaks the flow of heat from the flue to the incubator.

22 denotes a thimble or ferrule arranged upon and surrounding the branch pipe 20, and between said pipe and the thimble is placed a packing of asbestos or other protective material 23, the object of which is to prevent overheating of the woodwork of the incubator where the branch pipe 20 enters the same.

22L denotes a hood or bell which is adapted to surround and to be supported upon the flue 19 near the lower end of the incubator. 25 denotes a branch pipe projecting laterally from the hood or bell 24, the pipe 25 entering the ventilating-chamber 13 of the incubator and being provided with a surrounding packing and thimble 26 and 27, similarto the arrangement on the pipe 20. An annular series of holes 28 is formed in the upper portion of the hood 24, the object of which is to permit the escape of the heat at this point.

29 denotes a shelf or bracket arranged beneath the lower end of the flue 19, being supported in this position by means of an inclined arm 30, having a pivotal connection at its upper end with the under side of the incubator. The shelf is further supported by means of a wire 31, fastened at its upper end to the incubator and connected at its lower end to the lower end of the arm 30. This method of supporting the shelf permits the same to be swung to one side to allow the lamp-chimney to be inserted in the lower end of the flue, the shelf being then swung back to support the lamp.

32 denotes the usual damper mechanism arranged on the top of the incubator and automatically controlled by the thermostat 33, arranged within the incubator, as shown.

In operating the incubator the eggs are arranged in the hollow of the egg-tray after the manner of the eggs in a hens nest, the large volume of heat that is held above the same by the flannel partition or diaphragm and allowed to slowly pass through the same to the eggs simulating the warmth from the hens body when covering the eggs, a perfect circulation of the airbeing provided for through the ventilating -fiues 14, chamber 13, and hood 24.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In an incubator, the combination with a casin g having an egg-tray supported therein, of a fabric partition or diaphragm arranged above said egg-tray, means for supplying heated air to the incubator above said fabric diaphragm, means for directing the hot air from said fabric diaphragm to the center of the incubating-chamber above the egg-tray, and means for permitting the air to escape more or less slowly from beneath said screen or diaphragm located below said egg-tray, substantially as described.
