CYRUS W. ZIMMER, OF FORT IVAYNE, INDIANA, ASSIGNOR TO ROBERT N. DEAN, OF FORT IVAYNE, INDIANA.

INCUBATOR.

SPECIFICATION forming part of LettersPatent No. 762,371, dated June 14,1904.

Application filed October 26, 1903. Serial'No. 178,527. (No model.)

To all whom, it may concern:

Be it known that I, OYRUs W. ZIMMER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of In- 5, diana, have invented certain new and useful Improvements in Incubators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains IO to make and use the same, reference beinghad to the accompanying drawing, and to the let ters and figures of reference marked thereon, which forms a part of this specification.

This invention relates to improvements in I incubators; and the object thereof is to aflord a construction whereby a uniform atmospheric condition will be effected within the hatching-chamber in respect to both moisture and temperature.

I accomplish my objects by the construction illustrated in the accompanying drawing, which shows in perspective the hatching-case with one end cut out to expose the interior.

Referring now to the drawing, 1 is a hatch- 2 5 ing-case the sides and ends of which consist each of an inner sheathing 2, composed of open woven wire, and an outer sheathing 3 of the same material. These sheathings are arranged apart, so as to hold between them a Sheets 5 and 6 of thin cloth are interposed between the said feathers and the sheathings, respectively, so as to prevent the feathers from escaping through the meshes of the sheathings.

A convenient manner of constructing the case 1 is to form side and end frames A and B and secure the sheathings 2 and 3, respectively, at the inner and outer faces of said frames, inclosing the wall of feathers therein,

4 and then securing the ends of said frames together, so as to form the rectangular case 1.

By the use of feathers supported by openmesh sheathings the air within the hatchingchamber 7 is easily kept fresh and of uniform temperature, and because of the absorbent nature of the feathers and the ready access of the air within and external of the hatchingchamber the atmospheric condition respecting moisture within the hatching-chamber is maintained at such a degree as I have found best 5 suited for the incubation of eggs.

The air within the hatching-chamber is heated in the usual manner, and the heat therein becomes diffused by the feathers rather than reflected, as is the case where hard walls of Wood or composition are used.

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

1. In an incubator, a hatching-case, the ends 50 and sides of which consist of walls of feathers suitably supported by permeable sheathings.

2. In an incubator, a hatching-case composed of side and end frames; inner and outer permeable sheathings secured respectively at 5 the opposite faces of said frames; and walls of feathers arranged within said frames and between said sheathings.

3. In an incubator, a hatching-case, the sides and ends of which are composed of walls of 7 feathers; woven wire sheathings arranged upon the opposite sides of said walls and affording support for same; and sheets of thin cloth interposed between said walls and sheath ings.

In testimony whereof I aflix my signature in presence of two witnesses.

CYRUS W. ZIMMER.
