Improvements in "Foster Mothers "
66
or Rearers " for Rearing the
Young of Poultry and Game.
HARRY THOMAS STRANGE, of "Lion House," Harrow Weald, in the County of
Middlesex, Clerk, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the heating ventilating and construct-
ing "Foster Mothers" "Outdoor Rearers" and the like used in the rearing of the
young of poultry and game.
The dormitory of this apparatus with a movable slanting roof with gable ends
is enclosed with four vertical sides with a bottom of galvanized or other wire
supporting a floor on which the young birds rest. This floor may be removed
when required, and over it at an angle and at a suitable distance a saddle-shaped
metallic reservoir is fixed into which is conveyed by a tube the heat generated from
the oil or gas lamp fitted in an adjoining chamber through which a continuous
stream of fresh warm air is supplied to the dormitory, also to a covered run, and
to a separate nursery for those birds requiring extra care and warmth.
This nursery is constructed partly in a slanting roof with gable ends and adjoins
the dormitory it being constructed on the same framework, and is also situated
above the lamp chamber, and through it runs the hot air pipe forming the outlet
to the reservoir. Into this pipe telescopes another tube running at an angle to
the top of and through the covered run and terminating outside the roof where it
is provided with a suitable ventilator.
This run is enclosed with glass with wire netting, and wood and having no floor
the young birds being free to run upon the ground or grass approached by the
hatchway provided in the dormitory and the whole is so constructed that it may
telescope by a horizontal movement over the dormitory by sliding rods or by any
other suitable means thereby providing an extra covering during the winter
months.
Another run is also provided consisting of a framework constructed of rods
covered by a netting of twine or thread or other suitable material and is so made
that the rods may slide or telescope into receptacles provided inside or outside the
frame of the run adjoining.
The covered run and dormitory with adjacent chambers, may when extended be
closely fastened together by screws or by any other sufficient fastening and wheels
and handles are provided so that the whole apparatus may be transferred from
place to place more easily.
It may be seen that this "Foster Mother" or apparatus constructed on a
telescopic principle includes a dormitory, a covered run, and a separate nursery
which are heated from a generator of heat, contained within a separate and distinct
chamber, which also gives light to the dormitory and covered run when required;
the products of combustion being directly conveyed into and through a saddle-
shaped reservoir from whence it flows into and through a telescopic tube forming a
hot air pipe which runs at an angle to the top of the dormitory nursery and covered

page_text: run respectively and passing thence into the atmosphere while fresh air is conveyed
into the apparatus through perforated plates in the lamp chamber from whence
through other perforations a continuous stream of fresh warm air flows into the
dormitory the nursery and covered run and eventually escaping with any organic
vapour through suitable outlets in the roof.
Improvements in "Foster Mothers" or "Rearers" for Rearing the
Young of Poultry and Game.
HARRY THOMAS STRANGE, of 14, Spring Gardens, Charing Cross, S.W., late of
"Lion House," Harrow Weald, Middlesex, Clerk, 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 the heating ventilating and constructing
"Foster
Mothers" "Outdoor Rearers" and the like used in the rearing of the young of.
poultry and game.
-
This apparatus comprises "A" a dormitory or hot air chamber. Its dimensions
are length 2 feet 11 inches breadth 2 feet and depth 1 foot 8 inches.
The roof is but 2 feet 7 inches in length and is movable so as to facilitate the
necessary cleansing of this chamber. Its end adjoining "B" forms a triangle but
is without boards and in the opposite end an opening (a) is provided for ventilation.
Over the bottom framework of this compartment galvanized wire netting is fixed
This drawer is fitted
by small strips of wood and on these the drawer (b) runs.
with earth or any other suitable flooring for the young birds to rest upon and is
made to slide outwards for the effectual cleansing of the floor daily.
At a suitable distance from the floor a saddle-shaped metallic reservoir (n) is
supported on iron rods.
The hot air pipe (c) traverses the triangular space formed by the sloping roof.
Between the reservoir and pipe and parallel with the floor a framework of woollen
felt or other similar material may be fitted so as to lessen the air space within the
chamber so that an uniform degree of heat may be secured during the winter-the
sides of this chamber may also be padded with similar material for a like purpose.
To prevent the chamber "C" from being withdrawn too far wooden uprights are
provided on the outside of "A" as shewn at (p) and the inside of "C" extending
between the two lengths of tubing, and overlapping, thus assists in making the
chamber when extended weather-proof.
I may also provide in this chamber a glass panel to obtain a view of the young
birds inside the dormitory without opening the sliding panel (r).

"B" comprises three storeys of unequal dimensions. The lower storey Bd com-
C" by
municates with the dormitory by a hatchway (e) and with the covered run
means of a hinged flap.
The middle storey B contains the source of heat an oil or gas lamp and directly
communicates by a closely fitting chimney provided with an iron bend (g). On the
inner sides of this storey windows as shewn at (s) are provided for the transmission
of light into "A" and "C." On the outer sides two sheets of perforated zinc
are fixed one being in the door (y)-for the admission of atmospheric air into
the dormitory and other parts of the apparatus; access being obtained through
openings protected by similar sheets and covered by sliding panels for regulation
purposes.

page_text: The ceiling of this compartment is protected by a metal plate with an opening
in its centre fitted with a tube (i) directed into the top storey Bi.
This tube being above the lamp chamber conveys the heat immediately under the
hot air pipe and thus secures a better circulation of air in this pipe and at the
same time supplies the atmospheric air at a higher temperature to the chamber B
above thus forming a nursery for those birds requiring extra care and warmth-
ventilation being provided by perforations as before described on the inner side of
this chamber which is closed by triangular shaped doors access being obtained
thereto through the front of the roof of the covered run. (w) is a glass panel.
The covered run "C" is boarded with ths or ths inch matchboarding-the
back and the adjoining half of the roof permanently. The front or flap (v) is of
the like material and hung with flap hinges and underneath is provided a frame-
work of small mesh wire netting which encloses this compartment when the boarded
flap is not required.
The front of this covered run is fitted with a frame and glass partition E with a
perforated zinc ventilator (k) so that when the apparatus is closed a sufficient
supply of atmospheric air may be continued. On the opposite side of this chamber
a similar ventilator is provided.
"
The covered run "C" telescopes horizontally over A" and "B" by means of
rollers mortised in the bottom framework of the two sides care being taken to allow
but a very small surface of the rollers to project beyond the surface of the surround-
ing woodwork so as not to raise this structure materially from the ground. Angle
irons () are provided for the rollers to run upon when closed.
These irons must be projected some few inches from the bottom ends of "B" so
that the open end of "C" may be kept in position when the apparatus is extended.
Greater strength is also given to this end by an angle bracket screwed to the
rafters forming the apex.
At the top and bottom of the two sides of "C" brass or similar tubes as shewn
at (m) are securely fixed and the lower tubes must be fixed as near to the ground as
possible.
Into these tubes smaller tubes or iron rods (x) are made to telescope.
To these tubes or rods by means of small rings or by any other suitable fastenings
flexible netting or other suitable material is fitted and when the rods with the
material are fully extended a quadrangular space is entirely enclosed forming an
open run marked "D" for the young birds and at the same time being sub-
stantially protected from outside danger. When placed on uneven ground or
otherwise pegs are provided to keep the rods nearest the ground secure.
Entrance is obtained into this run by a hatchway which may be closed by a
sliding panel. When desirous of keeping this panel raised a piece of wire attached
to a screw in it may be slipped through a hole some few inches above it and looped
"C."
over a second screw placed a few inches below on the inside of the covered run
When the open run is not in use and the rods carrying the netting are telescoped
into the tubes the netting is pocketed within the space reserved for it at the end
of "C" as shewn at C on the longitudinal section.
Into the closed chamber Cb above this space the products of combustion are
directly conveyed through the hot air pipe adjoining & its outlet is capped and a
ventilating aperture in the end is protected by a metal sheet. The bottom of this
aperture must be slightly above the level of the bottom of the cap covering the
outlet.
Wheels are provided so that the apparatus may be transferred from place to place
more easily and handles are provided to the framework at the opposite end for the
purpose.
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 The arrangements and combination of parts constituting the telescopic or

page_text: extending apparatus hereinbefore described and represented in the drawings
annexed.
2. A run constructed of rods or tubes and covered by flexible netting or other
suitable material and fitted together so as to slide telescopically one within or over
the other substantially as herein described.
