INGUBATOR.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed May 25,1905. Serial No. 262.168.

To all whom it may concern.-

Be it known that I, GRANT M. CURTIS, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Incubators, of which the following is a specification.

This invention relates to incubators, and particularly to a chick-drawer therefor.

In the drawings, Figure l is an elevation of an incubator, showing also a partial cross-section through the egg-tra and through a chick-drawer embodymg this invention; and Fig. 2 is a perspective view of the same chickdrawer.

In the form of incubator shown in the drawings and illustrating the present invention there is an incubator-casing 1, having within it an e g-tray 2, a door or window 3, through which ight may pass into the egg-chamber 4, containing the egg-tray, and beneath the egg tray a chick-drawer 5 of a construction to be particularly described. Means are provided for permitting the chicks that are hatched from the eggs in the egg-tray to pass into the chick-drawer. In the present. instance the egg-tray 2 has less depth than the incubator, so that adjacent to the glazed door or window 3 there is a space 6 between the front end of the tray 2 and the door or window 3, through which the chicks may drop into the space below the egg-tray. It is well known that chicks when hatched tend to move toward the light. The chick-drawer 5 is, however, dee er than the egg-drawer, so that there shall be a portion of the chick-drawer under the chick-space 6, above mentioned.

In artificial incubation it is important to remove the chicks at intervals from the incubator to brooders or to other means for maintaining the chicks in an atmosphere suitably warmed and ventilated and to provide them with food. It is further important to handle the chicks as little as possible. In order to provide suitable means of retaining the chicks in the chick-drawer when carryin them from the incubator to the breeder (vfinch latter may be a considerable distance from the incubator) and for protecting them from the air, the chick-drawer is provided with a cover, always attached to the drawer and capable of being opened and closed to cover and uncover the drawer. In the present instance of this invention this cover is of the roller-blind type, and there is journaled in the rear end of the drawer a springroller 7, having wound upon it the curtain 8, which curtain has at suitable intervals the transverse slats or stifi'eners 9, whose ends slide in guideways 10 in the sides of the drawer. Means are provided also in the cord 11 for pulling out the curtain to cover the drawer. The roller-blind cover is of the well-known form and is adapted to roll up the curtain when the same is free. Means are provided for maintaining the curtain in its extended position. These may be the cord itself, which may be tied about a cleat, such as the handle 12; but a simpler form of maintaining the curtain in its extended position is that at the end of the guidewa r 10 a short extensiomguideway 13 is provided, in which the end slat may run. The short guideway 13 is of such length that the edge of the end slat may ti u into a notch 14, where the slat is caug t by the pull of the spring-roller and held in the extended position.

What I claim is- 1. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer underneath the egg-tray adapted to receive the chicks as they pass therefrom, and a cover attached to said chick-drawer and adapted to be moved to cover the same.

2. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer underneath the egg-tray adapted to receive the chicks as they fall therefrom, and a roller-blind cover attached to the chick-drawer and adapted to be extended to cover said drawer.

3. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer underneath the egg-tray adapted to receive the chicks as they fall therefrom, a roller-blind cover attached to the chick-drawer and ada ted to be extended to cover said drawer, an means for fastening said cover in its extended position.

4. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer under the eggtray adapted to receive the chicks as they pass therefrom and having uides on the sides of said drawer, and a r01 er-blind cover in said drawer having transverse stifi'eners whose ends run in said guides, the said cover being extended to cover the drawer.

5. in an incubator having an egg-chamber, an egg-tray therein, adapted to permit the chicks to pass from the egg-tray into the space thereunder, a chick-drawer under the egg-tray adapted. to receive the chicks as they pass therefrom and having guides on the sides of said drawer, a roller-blind cover in said drawer having transverse stiffeners whose ends run in said guides, the said cover being extended to cover the drawer, and means for fastening said cover in its extended position.

6. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the eg -tray into the space thereunder, a chick-drawer underneath the eggtray adapted to receive the chicks as they fall therefrom, a roller-blind cover attached to the chick-drawer and ada ted to be extended to cover the drawer, an a cord attached to said cover for extending the same and for fastening it in its extended position.

7. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer under the eggtray adapted to receive the chicks as they pass therefrom and having guides on the sides of said drawer, a roller-blind cover in said drawer having transverse stiffeners whose ends run in said guides, the said cover being extended to cover the drawer, and a cord attached to said cover for extending the same and for fastening it in its extended position.

8. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from. the egg-tray into the space thereunder, a chick-drawer under the eggtray adapted to receive the chicks as they pass therefrom and having uides on the sides of said drawer, and a rol er-blind cover in said drawer having edges engaging said guides, thesaid cover being extended to cover the drawer.

9. In an incubator having an egg-chamber, an egg-tray therein, adapted to permit chicks to pass from the egg-tray into the space thereunder, a chick-drawer under the eggtray adapted to receive the chicks as they pass therefrom and having uides on the sides of said drawer, a rollerlind cover in said drawer having edges engaging said guides, the said cover being exten ed to cover the drawer, and means for fastening said cover in its extended position.
