PROVISIONAL SPECIFICATION.
An Incubator for Hatching the Eggs of Poultry or Game by Hot
Vapour and Hot Air.
JOHN WILLIAM ELLIS Pike Lane Thetford, Fowl Breeder JAMES MAYES Elvedon
Game Farm Game Keeper and Game Breeder do hereby declare the nature of this
invention to be as follows:-
Our invention consists in improvements in Incubators for hatching eggs by hot
vapour & hot air. The improvement in our invention conveys the hot air to the
interior of the Incubator from a gas or lamp flame or other combustible placed beneath
the Incubator, through a tube which passes through a tank containing water. The
quantity of hot air & vapour admitted is regulated by means of a metal disc attached
to one end of a lever which carries an adjustable weight at its opposit end. The said
lever having a projecting knife edge as a fulcrum & pivot regulated by a float or
plunger fitted in a J shaped glass tube, the glass tube containing spirit and mercury.
An adjustment screw near the center of the lever is employed to act upon the float
or plunger to adjust the admission of heat into the Incubator by means of a damper
on the top of the aforementioned tube, which damper on being moved from the tube
causes the required amount of hot air to enter the Incubator. When there is more
heat than is required the mercury rises lifting the plunger which acts upon the lever
& then causes the damper to be closed against the end of the tube. The heat is then
carried through another tube which passes through the water tank to the outward air
thereby causing the vapour to rise & the temperature in Incubator to be lowered.
2nd. To obtain the requisit amount of moisture the eggs are placed upon a surface
of canvas to which are attached lose twisted strings suspended below & hanging into
metal trays containing water, the water being brought into contact with the eggs
by capillary attraction.
3rd. The aforesaid trays being reversable and interchangable, the eggs are turned
automatically without handling when the trays are reversed.

An Incubator for Hatching the Eggs of Poultry or Game by Hot
Vapour and Hot Air.
JOHN WILLIAM ELLIS Pike Lane Thetford Fowl Breeder and JAMES MAYES
Elvedon Game Farm Game Keeper & Game Breeder 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 :-
Our invention consists in improvements in incubators for hatching eggs by hot
vapour and hot air. The improvement in our invention conveys the hot air to the
interior of the incubator from a gas or lamp flame A or other combustible placed
beneath the incubator as shown in figures 1 and 2 through a tube B which passes
through a tank L containing water the quantity of hot air and vapour admitted being
regulated by means of a damper C attached to one end of a lever D which carries an
adjustable weight E at its opposite end the said lever D having a projecting knife
edge F as a fulcrum or pivot regulated by a float or plunger G fitted in a U shaped
glass tube H. The glass tube containing spirit and mercury. An adjustment screw J

page_text: near the centre of the lever D is imployed to act upon the float or plunger G to adjust
the admission of heat into the incubator by means of a damper C on the top of the
aforementioned tube B which damper C on being moved from the tube B causes the
required amount of hot air to enter the incubator. When there is more heat than is
required the mercury rises lifting the plunger G which acts upon the lever D and thus
causes the damper to be closed against the end of the tube B the heat is then carried
through another tube K which passes through the water tank L to the outside air
thereby causing the vapour to rise and the temperature in incubator to be lowered.
To obtain the requisite amount of moisture beneath the eggs they are placed in trays R
having a canvas bottom M to which are attached loose twisted strings N suspended
from the canvas and dipping into metal trays P containing water, the water being
brought into contact with the eggs by capillary attraction. The aforesaid trays Rare
placed upon an incline plane having a loose piece of wood S at the top end covering
the space of half an egg the trays R then being reversed and the piece of wood S
taken out and again placed at the top thereby causing the eggs to make half a
revolution the said trays R being reversable and interchangeable the eggs are turned
automatically without handling when the trays R are reversed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1st. Constructing incubators with an open metal tank placed inside incubator.
2nd. The form of regulator for controlling the heat and vapour in incubator.
3rd. The egg trays being made reversable and interchangeable for turning the eggs,
and furnished with dippers as hereinbefore described.
