Improvements in and connected with Apparatus for Use in Rearing
Chickens and other Young Birds.
I CHARLES EDWARD HEARSON of No. 5 Templar Street Camberwell in the.
County of Surrey Engineer do hereby declare the nature of this invention to be as
follows:-
In constructing according to my invention apparatus for use in rearing chickens
and other young birds I form an oblong frame of wood to one end of which frame
1 apply a handle and to the other end wheels in order to admit of the apparatus
being readily moved from place to place by raising the handle end and pushing the
said apparatus in the same manner as a wheel barrow. Within the said frame and
at one end thereof (preferably the wheel end) I construct a compartment having a
raised floor and a hinged cover which compartment constitutes the sleeping box for
the chickens or other birds and is provided with the heating and ventilating arrange-
ments hereinafter described and an aperture for ingress and egress of the birds
from and to the enclosure formed by the other part of the frame which enclosure
is without flooring and constitutes the "run." Within the said sleeping box and
between the said aperture and the heating arrangements I arrange a curtain of
flannel or other suitable material supported by a removable rod or bar and outside
the said aperture I arrange an inclined board to facilitate access of the birds from
the run to the sleeping box. The upper part of the said frame I cover with
inclined flaps hinged at one side to the said frame and fastened thereto at the
opposite side by means of "side hooks" having counterpoises formed on them by
which the unfastening of the said hooks by vibration due to the action of wind is
prevented. In one side of the part of the said frame which encloses the run I form
openings and fit therein sheets of glass in such a manner that they may be shifted
or entirely removed to allow of the admission of air to the run when desirable and
I secure wire netting over the said openings on the outerside of the said frame.
I also form openings in the lower part of the said frame below the sleeping box
through which openings air passes to the interior of the said box through the
ventilating arrangement hereinafter described.
The heating arrangement consists of a box or tank containing water and mounted
in the upper part of the sleeping box within which tank is a tubular compartment
separate from the water space and furnished with a removable partition and
communicating with the chimney of an oil lamp mounted within the run and adjacent
to the sleeping box the burner of which lanp is surrounded by a glass cylinder into
which air passes through perforations in the bottom of a shield arranged above the
said burner and enclosing the chimney of the lamp and a portion of the water tank
which projects from the sleeping box. The said water tank is furnished with a
nozzle through which it is charged with water and with an overflow pipe and a pipe
for the exit of air and steam and an emptying pipe which nozzle and overflow pipe
and emptying pipe are closed by suitable plugs or stoppers when necessary. The
said shield which is designed to prevent the extinction of the flame of the lamp by
currents of air bas an aperture formed in its upper part through which the upper
end of the chimney of the lamp passes. To provide for the passage of air to the
Hame of the lamp holes are formed in the lower part of the said shield and other

page_text: holes are formed in the upper part thereof around the aperture through which the
chimney passes: To prevent unsteadiness of the flame being caused by the air
entering through the said boles a baffle is secured within the lower part of the
shield and another baffle is secured on the top of the shield around the chimney
aperture and a cap is also secured on the top of the shield which cap encloses the
air holes in the top of the shield and the baffle secured thereon and has openings
formed in it in such a manner that air entering through them is directed
downward.
The arrangement for ventilating the sleeping box consists of a metal tube passing
through the water space of the heating tank and secured in the top and bottom of
the said tank and projecting below the bottom thereof and passing through an
aperture in the bottom of the sleeping box. By means of the said tube which is
open at both ends the air which passes through the openings in the side of the
frame below the floor of the sleeping box is conducted to the upper part of the
said box becoming heated in its passage. The air thus entering the sleeping box
passes out by the aperture which is provided for ingress and egress of the birds.
In order to admit light from the lamp to the sleeping box I form an aperture in
the side thereof adjacent to the lamp burner in which aperture I arrange a grid
and I provide for closing the said aperture when desirable by means of a shutter
mounted in slides.

Improvements in and connected with Apparatus for Use in Rearing
Chickens and other Young Birds.
I CHARLES EDWARD HEARSON of No. 5 Templar Street Camberwell in the
County of Surrey Engineer 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 :-
I will describe my invention with reference to the accompanying drawings
Figure 1 of which is a side elevation Figure 2 a horizontal section Figure 3 a
longitudinal section and Figures 4 and 5 transverse sections of apparatus constructed
according to my invention for rearing chickens and other young birds. The section
Figure 2 is taken on the line A A Figure 3. The section Figure 3 is taken on the
line B B Figure 2 and the sections Figures 4 and 5 are taken respectively on the
lines CC and DD Figure 3. Figures 6, 7, 8, 9 and 10 are details hereinafter
referred to.
In the following description the parts of the drawings are referred to by means
of the letters and figures marked thereon. The same letters and figures of reference
indicate the same parts in all the figures of the drawings.
The said apparatus consists of an oblong frame of wood' a, a a to one end of
which frame is applied a handle band to the other end wheels c, c in order to admit
of the apparatus being readily moved from place to place by raising the handle end
and pushing the said apparatus in the same manner as a wheel barrow. Within
the said frame a and at one end thereof (preferably the wheel end as shown in the
drawings) is constructed a compartment d having a raised floor e and a hinged
cover preferably lined on the underside with a casing d packed with sawdust or
other bad conductor of heat which compartment constitutes the sleeping box for

page_text: "
the chickens or other birds and is provided with the heating and ventilating
arrangements hereinafter described and an aperture g for ingress and egress of the
birds from and to the enclosure h formed by the other part of the frame a which
enclosure is without flooring and constitutes the "
run. Within the said sleeping
box or compartment d and between the aperture g and the heating arrangements is
arranged a curtain of flannel or other suitable material i supported by a removable
rod or bar i¹ and outside the said aperture is arranged an inclined board k to
facilitate access of the birds from the run to the sleeping box d and a perforated
door g' by which exit of the birds from the said sleeping box may be prevented.
The upper part of the frame a is covered with inclined flaps hinged at one side
to the frame a and fastened thereto at the opposite side as shown in Figure 1 by
means of "side hooks " mm having counterpoises m² m² formed on them by which
the unfastening of the said hooks by vibration due to the action of wind is prevented.
In order to show clearly the form of the said side hooks one of them is represented
on a large scale in Figures 6 and 7. In one side of the part of the frame a which
encloses the run openings are formed in which are fitted sheets of glass n, n (see
Figure 2) in such a manner that they may be shifted or entirely removed to allow
of free admission of air to the run when desirable and on the outer side of the said
frame over the said openings wire netting is secured as shown at o o in Figure 1.
In the lower part of the said frame below the sleeping box d holes pp are formed
through which holes air passes to the interior of the said box through the ventilating
arrangement hereinafter described. At the outer end of the "run is an opening q
provided with a door q¹ which admits of exit of the birds from the apparatus when
desirable.
The heating arrangement consists of a box or tank containing water and
mounted in the upper part of the sleeping box d within which tank is a tubular
compartments separate from the water space and furnished with a removable
partition and communicating with the chimney t t of an oil lamp u mounted
partly under the sleeping box d and projecting into the run the burner of which
lamp is surrounded by a glass cylinder u' (see Figures 2 and 3) into which air
passes through perforations in the bottom of a shield arranged above the said
burner and enclosing the chimney tt' of the lamp and a portion of the water tank
which projects from the sleeping box d. By means of the partition which.
extends from the outer end of the tubular compartments to near its inner end the
heated air and products of combustion from the lamp are caused to travel the
whole length of the said compartment twice before escaping from the upper part t¹
of the lamp chimney. The water in the tank r is thus effectually heated by the
said heated air and products of combustion and the heat radiated by the said tank
keeps the interior of the sleeping box d at a sufficiently high temperature. The
said water tank r is furnished with a nozzle through which it is charged with
water and with an overflow pipe which also admits of exit of air and steam
from the tank and an emptying pipe 3. The said nozzle and the emptying
pipe are provided with caps as shown or with plugs or stoppers by which
they are closed when necessary. The construction of the shield which
is designed to prevent extinction of the flame of the lamp by currents of
air is hereinafter described with reference to Figures 8, 9 and 10. Figure 8
being an enlarged section of the said part corresponding to the section shown
in Figure 3 and Figures 9 and 10 being horizontal sections taken respectively
on the lines E E and FF Figure 8. is an aperture formed in the upper part of
the said shield through which the upper end of the chimney of the lamp u passes.
To provide for the passage of air to the flame of the lamp holes v³ ³ are formed in
the lower part of the said shield and a portion of the bottom of the said shield
which rests on the top of the glass cylinder of the lamp and on which the
chimney of the lamp rests is formed of perforated metal or wire gauze as shown
in Figures 8 and 10 and holes are formed in the upper part of the said shield
around the aperture through which the chimney passes. To prevent unsteadiness

page_text: -1
t
of the flame being caused by the air entering through the said.. holes v²² vv a
baffle is secured within the lower part of the shield; and. another baffle is
secured on the top of the shield around the chimney aperture and a cap v' is also
secured on the top of the shield which cap encloses the air holes in the top, of
the shield and the baffle ve secured thereon and has openings formed in, it in
such a manner that air entering through them is directed, downward the said
openings being formed by making short slits or incisions horizontally in the sides
of the part and pressing the metal above them inward as shown at ..and
pressing the metal below the said slits outwards as shown at 10 v10.
The arrangement for ventilating the sleeping box consists of a metal tube w
passing through the water space of the heating: tank r and secured in the top and
bottom of the said tank and projecting below the bottom thereof and passing
through an aperture in the bottom of the sleeping box d. By means of the said
'tube which is open at both ends the air which passes through the holes p p in the side
of the frame a below the flour e of the sleeping box is conducted to the upper part
of the said box becoming heated in its passage by the water in the tank r. The
air thus entering the sleeping box passes out by the aperture g which is provided
for ingress and egress of the birds or through the perforations in the door g, and
through holes d d in the side of the sleeping box above the said door if it be closed.
In order to admit light from the lamp u to the sleeping box d I form an
aperture in the side thereof adjacent to the lamp burner in which aperture
I arrange a grid as shown in Figure 4 and 1. provide for closing the said aperture
when desirable, by means of a shutter y mouuted in slides zz as also shown in
Figure 4.
Having now particularly described and ascertained the nature of my said
invention for: "Improvements in and connected with apparatus for use in rearing
chickens and other young birds" and in what manner the same is to be performed
I wish it to be understood that I make no general claim either to the mounting of
such apparatus on wheels or to the use of a lamp for heating the sleeping box but
I: declare that I claim as my said invention ;-
