Improvements in and relating to Chicken Rearers.
We, GEORGE EDWARD O'BRIEN, Clerk in Holy Orders of The Vicarage, Bosley,
Congleton, and CHARLES WILLIAM LILLIE and CHARLES ARTHUR DAY, both of
39 Mill Street, Macclesfield, Manufacturing Ironmongers, do hereby declare the
nature of this invention to be as follows :-
This invention relates to improvements in and relating to chicken rearers for use in
rearing chickens, and our invention consists in the especial arrangement and
combination of parts as will be hereinafter described.
It is well known that in chicken rearers of the hitherto usual construction, there
is only one sleeping chamber which is kept at such a degree of warmth as is necessary
for the very youngest birds, say birds up to three weeks of age, after which it is
necessary to transfer said birds to the cold rearer, but inasmuch as the birds at the
age referred to are still too young to withstand cold, it is necessary, at least in the
winter months, to provide the said cold rearer with a lamp or other means for
supplying heat. In the chicken rearer constructed in accordance with our inven-
tion we divide the sleeping chamber into two compartments by means of a suitable
At the rear
partition, said partition having a door which is normally kept closed.
and outside of the sleeping chamber we provide a lamp, the hot air and gases from
which pass through a flue which travels around both compartments of the sleeping
chamber. The said flue is situated at the top of the sleeping chamber and the
portion of the flue which travels round one compartment is of greater diameter than
the portion which passes around the other compartiment, the arrangement being
such that the hot air and gases enter the flue at its larger end and escape at the
smaller. The consequence of this construction and arrangement of the flue is that
the compartment, in which the flue is of greater diameter, is maintained at a higher
degree of warmth than the compartment in which the flue is of smaller diameter
owing to the greater heating surface of the flue in the former compartment, and also
owing to the hot air and gases having become partially cooled when they enter
the portion of the flue which is situated in the other compartment.
The reason we have the two compartments in the sleeping chamber is that the one
which is maintained at a higher temperature is used as a sleeping place for the very
young birds, say birds up to three or four weeks of age, after which said birds are trans-
ferred through the door in the partition above referred to into the chamber which is
maintained at a lower temperature, and a fresh batch of young birds placed in the
warmer chamber.
By means of a chicken rearer having a sleeping chamber divided into two com-
partments as above described, we are enabled to simultaneously rear two hatches of
chickens in one rearing apparatus, the heat being supplied to both sleeping com-
partments by means of a single lamp or other heating apparatus as described.
We wish it to be understood that we do not confine ourselves to any particular
shape of the different parts constituting our invention, also that our improved
apparatus for rearing chickens may be provided with the necessary railing and other
fittings to make a run for the birds in any usual manner, also we prefer to provide a
galvanized iron or other suitable plate on the underside of the preferably movable
roof with which the sleeping chamber is provided, said plate serving to deflect the
heat, and in order that the heat shall be better retained we prefer to line the

felt or the like.

improvements in and relating to Chicken Rearers.
We, GEORGE EDWARD O'BRIEN, Clerk in Holy Orders, of The Vicarage, Bosley,
Congleton, and CHARLES WILLIAM LILLIE, and CHARLES ARTHUR DAY, both of
39 Mill Street, Macclesfield, Manufacturing Ironmongers, 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:-
This invention relates to improvements in and relating to chicken rearers for use
in rearing chickens and our invention consists in the special arrangement and com-
bination of parts as will be hereinafter described.
It is well known that in chicken rearers of the hitherto usual construction, there
is only one sleeping chamber, which is kept at such a degree of warmth as is
necessary for the very youngest birds, say birds up to three or four weeks of age,
after which it is necessary to transfer said birds to the cold rearer; but inasmuch
as the birds at the age referred to are still too young to withstand cold, it is
necessary at least in the winter months-to provide said cold rearer with a lamp
or other means for supplying heat. This defect is obviated by our invention, and
in order that our invention may be readily understood reference is made to the
accompanying drawing which represents our improved chicken rearer in plan view,
the roof being removed.
In our improved chicken rearer the sleeping chamber is divided into two com-
partments A, B, by means of a suitable partition C, said partition having a suitable
door preferably swung horizontally by means of hinges c, which door is normally
kept closed.
At the rear and outside of the sleeping chamber we provide a lamp D the hot air
and gases from which pass through a flue E, E¹, which passes around both com-
partments of the sleeping chamber and is supported by supports e.
The said flue is
situated at the top of the sleeping chamber and the portion E of said flue which
is situated in the compartment A is of greater diameter than the portion E' which is
situated in the compartment B the arrangement being such that the hot air and
gasses enter the flue at the larger end and escape at the smaller. The result of this
construction and arrangement of the flue and its combination with the chamber
divided into two compartments is that the compartment A is maintained at a higher
degree of warmth than the compartment B owing to the fact that the flue in the
former compartment presents a greater heating surface to that presented by the flue
in the compartment B and also owing to the fact that the hot air and gases have
become partially cooled when they enter the flue in the compartment B.
By means of a chicken rearer constructed as described two batches of chickens can
be simultaneously reared, the very young birds-say birds up to three or four weeks
of age being kept in the compartment A which is warmer, and the older birds in
the compartment B which is not so warm. After a sufficient lapse of time the older
birds are removed from the rearer into the open and the younger birds are trans-
ferred from the compartment A into the compartiment B through the door swung
on c and a fresh batch of young birds introduced into the compartment A; and to

page_text: permit of the ready removal or introduction of the birds we provide the rearer with
suitable doors which are preferably swung horizontally on hinges a, b.
By means of a chicken rearer having a sleeping chamber divided into two com-
partments as above described, we are enabled to simultaneously rear two batches of
chickens in one rearing apparatus, the heat being supplied to both sleeping com-
partments by means of a single lamp or other heating apparatus as described.
We wish it to be understood that we do not confine ourselves to any particular
shape of the different parts constituting our invention, also that our improved
apparatus for rearing chickens may be provided with the necessary railing and other
fittings to make a run for the birds in any usual manner, also we prefer to provide a
galvanized iron or other suitable plate on the underside of the preferably movable
roof with which the sleeping chamber is provided, said plate serving to deflect the
heat, and in order that the heat shall be better retained we prefer to line the inside
of the roof with preferably wire-woven and also non-conducting felt or the like.
Further, instead of rearing chickens we may rear any other birds for which our
apparatus is suited and the flues E E¹ may be tapered instead of parallel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. An improved chicken rearer having two compartments such as A. B. relatively
maintained at different degrees of warmth for the purposes described.
2. An improved chicken rearer having two compartments such as A, B, relatively
maintained at different degrees of warmth by means of a flue E, E', for the purposes
and substantially as described and illustrated.
3. An improved chicken rearer having two compartments such as A, B, relatively
maintained at different degrees of warmth both said compartments being warmed by
means of a single lamp or equivalent substantially as described and illustrated.
4. In a chicken rearer the combination of two compartments such as A, B,
relatively maintained at different degrees of warmth by means of a flue E, E¹, the
portion E of said flue presenting a larger heating surface than the portion E¹,
horizontally swung doors hinged respectively at a b and c and a detachable roof alĺ
for the purposes and substantially as set forth.
