COMPLETE SPECIFICATION.
An Improved House and Apparatus for Rearing Chicken and the
Young of other Birds.
I, HENRY STOPFORD TUNNARD of The Elms, Rugby, Gentleman, 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 houses and apparatus for the rearing
of chicken and other young birds, and consists of a rectangular or other suitably
shaped box or house having a hinged lid.
The interior of the said house is divided into two compartments, the one being
a chamber heated by an oil or gas lamp, or other suitable means, and the other
compartment forming a run for the chicken.
For the better explanation of my invention I append the accompanying sheets of
drawings in which
Fig. 1 represents a sectional plan of my improved apparatus.
. Fig. 2 is a longitudinal section of the same.
Fig. 3 shows an elevation of one of its ends.
Fig. 4 represents a transverse section through the run looking towards the warm
chamber.
Fig. 5 is a plan of a second lid or cover to the warm air chamber, situated a few
inches underneath the main lid of the house.
Fig. 6 represents a side elevation of the whole house.
The like letters of reference indicates the like parts throughout.
a is the outer case enclosing the whole apparatus which is divided into two
compartments. the artificially warmed compartment and c the run by means of
a cross partition d.
с
The warm air chamber b, consists of an inner casing, the sides of which do not
quite touch the outer casing a, and the partition d, the space thus left between the
casings a and b and d and b, being packed with felt or other suitable nou-conducting
material. The bottom of the compartment is raised several inches from the
ground level, and the compartment is provided with a hinged or other removable
lid, which is arranged a few inches below the cover of the whole house as before
mentioned.
Passing vertically through the warm chamber b is a metal cylinder e having a
flange formed thereon by which it rests on the floor of the chamber b, and having
a cover as shewn in Fig. 2.
The said cylinder is open one inch or less below the bottom or floor of the warm
chamber. The object of such cylinder e is 'to receive a "Hurricane" or other
suitable lamp which rests on a platform g attached by legs to the cylinder, and
forming the base thereof.
For the better distribution of heat throughout the compartment b a shallow
metal chamber h is affixed to the underside of the cover or lid of the compartment
fitting closely around the cylinder e and supported on a second flange formed on
the same. Corresponding holes i i are formed in the cylinder e and the chamber h, to
allow the hot air to pass freely from one to the other, whilst ventilating openings j,j,
are formed through the lid to admit of the escape of the warm air.
The packing felt or other suitable non-conducting material, is also placed
between the chamber h, and the bed of the warm chamber. A small glazed
opening k, is provided in the side of the warm chamber, to light its interior, and
fresh air is admitted by means of traversed inlets ll covered with perforated zinc
in two of its other sides.

page_text: It will be readily understood from the foregoing description that by means of
this apparatus, no foul air or the proceeds of combustion can penetrate into the
compartment, the air of which is warmed by contact with the.metal.cylinder, and
the chamber h, in communication therewith at the top, whilst the felt or other
suitable packing before mentioned, between the compartment and the outer
casing a, and d, conduces greatly to the retention of heat.
A small door furnished with a sliding lid is placed in the side of the compart-
ment adjoining the run c, and gives access to a removable tray or platform n
which is suspended by suitable means immediately outside the compartment b.
The bottom of the tray n, being on a level with the floor of the compartment b.
The object of this said tray n, is to contain food and water for the young birds,
who can go out to it through the door m.
A ladder way, or suitable inclined plane o, is placed from the door m to the
bottom or Hoor of the run (which is on the ground level) so as to permit the young
birds when strong enough to go down into the run at pleasure, at which time the
hanging tray n, may be removed and utilised at the other end of the run as a sand
receptacle or bath.
The far end of the run is furnished with a door p, which can be opened so as to
allow the birds to go in and out of the house if desired, and the hole run is lighted
and ventilated by means of a large opening, filled up with wire netting or other
suitable perforated material at the back of which is provided a sliding glazed sash
which is capable of covering the whole opening or a portion thereof as desired
see Figure 1. It is intended that in order to place the lamp or other heating
apparatus into position, or to remove it, it is necessary to lift the main lid of the
house, and also the lid of the cylinder e, but not the cover of the warm compart-
ment, and that the lamp may be seen and regulated from time to time without
raising the main lid and cover f, a small door or portion of it being glazed, is
placed immediately opposite to and on a level with the lamp, and to supply the
lamp with air for its combustion a suitable number of perforations are made in the
casing a, below the floor level of the warm chamber b.
The main lid or cover of the house is furnished with a stay-bar passing through
a staple which is fitted with a screw pin, as shewn in Fig. 4, so that the lid can be
held open to any desired extent.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
(1) In a rearing house or apparatus for chicken and other young birds, an
inner chamber placed within an outer case, the intervening space being packed
with felt, or other suitable non-conducting material, the same in combination
with a metal cylinder and hot air chamber, which receives the heat from a lamp
placed within the said cylinders and transmitted by radiation to the compartment
in which the same is situated.
(2) The warm compartment and cylinder above described in combination with
an outer hanging tray, and run, all substantially as described in the foregoing
Specification, and illustrated by the accompanying drawings.
Dated this 19th day of October 1891.
