PROVISIONAL SPECIFICATION.
Improvements in the Arrangements of the Egg-drawer of
Incubators.
I JANE HOOPER of Calcot Farm Sturry in the County of Kent do hereby declare
the nature of this invention to be as follows:-
The object of this invention being for the obtaining of better results in artificial
hatching and facilities for hatching ducks geese and waterfowl eggs in the same
drawer at one and the same time with the eggs of other birds which require less
moisture such as the domestic fowl game and turkeys. For this purpose I cause the
drawer to be constructed with an oblong opening in its centre the entire length of the
drawer for air to come through. On this is placed a wooden earthenware or metal
reservoir resembling the letter T inverted thus 1. Water impregnated with the
addition of salt is placed in it round the opening. The air arising through this opening
is split by playing on a V shaped piece of wood or metal at about one inch from the
top and being divided passes to the underside of the heating tank is warmed. It then
catches the moistened vapour and carries it over the eggs out of the ventilation holes
on one side of the drawer, and above it near where the heat is generated I prefer-
ably place a pipe open at both ends and having holes in it. This pipe goes from
front to back of the casing containing the tank and drawer and attracts the incoming air
charged with moisture giving an equable ventilation over the eggs. On the top of the
V shaped piece of wood or metal is a groove in which is a moveable partition so that
more moisture can be maintained one side of the drawer than the other.

1 JANE HOOPER of Calcot Farm Sturry in the County of Kent do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of this invention being for the obtaining of better results in artificial
hatching and facilities for hatching ducks geese and waterfowl eggs in the same
drawer at one and the same time with the eggs of other birds, which require less
moisture such as the domestic fowl game and turkeys. For this purpose I cause the

opening is split by playing on a V shaped piece of wood or metal at about one inch
from the top and being divided passes to the underside of the heating tank is warmed.
It then catches the moistened vapour and carries it over the eggs out of the ventilation
holes on one side of the drawer and above it near where the heat generated, I pre-
ferably place a pipe open at both ends and having holes in it. This pipe goes from
front to back of the casing containing the tank and drawer and attracts the incoming
air charged with moisture giving an equable ventilation over the eggs. On the top of
the V shaped piece of wood or metal is a groove in which is a moveable partition so
that more moisture can be maintained one side of the drawer than the other.
Also that the entire incubators could be made of tin or other metal.

tion and in what manner the same is to be performed, I declare that what I
claim is,
Improvements in the arrangement of the egg drawer of incubators.
