First Claim

1. An incubator which comprises a housing for accomodating eggs to be hatched;
- a tray within the housing, for supporting eggs, the tray being reciprocable with respect to the housing and being movable freely on roller means, and the tray being provided with two downwardly directed lugs;
dividers above the tray, to divide eggs on the tray into rows;
a flexible screen for placing over eggs on the support means;
heating means for heating air;
guide means for guiding air, heated in use by the heating means, above the flexible screen whereby, in use, the screen is heated and heat is conducted downwards through the screen so as to heat upper regions of eggs; and
motive means for intermittently causing relative movement between the tray and the dividers, thereby to cause intermittent rotation of any eggs on the tray, the motive means including a motor with an arm inclined to the shaft of the motor, such that actuation of the motor causes the arm, in one complete circular movement of the arm, to urge one of the two lugs and hence the tray in one direction and then to urge the other of the two lugs and hence the tray in the opposite direction, the arm carrying a roller means for rolling abutment against the lugs.

Abstract
An incubator is disclosed in which there is a support for supporting eggs, with a flexible screen intended to be positioned over the eggs when supported by the support. There is also provision for hot air to be passed over the screen so that heat is conducted downwardly through the screen to upper portions of the eggs. In addition, or as an alternative, there can be transverse dividers for dividing the eggs into rows on the support, with provision for relative movement on an intermittent basis between the support and the dividers so as to cause rotation of the eggs.

- a tray within the housing, for supporting the eggs, the tray being reciprocable with respect to the housing and being movable freely on roller means, and the tray being provided with two downwardly directed lugs;
heating means for heating air;
two parallel rows of notches, and dividers, for dividing eggs on the tray into rows, the dividers being positionable in the notches so that the distance between two adjacent dividers is slightly greater than the diameter of the eggs to be hatched; and
motive means for intermittently causing relative movement between the tray and dividers, the motive means including a motor with an arm inclined to the shaft of the motor, such that actuation of the motor causes the arm, in one complete circular movement of the arm, to urge one of the two lugs and hence the tray in one direction and then to urge the other of the two lugs and hence the tray in the opposite direction, the arm carrying a roller means for rolling abutment against the lugs.
