MARCO WILHELM MONTAUBAN-VAN-SWYNDREGT, of Coleman Street, in the City
of London. "IMPROVEMENTS IN INCUBATORS, PART OF SUCH IMPROVEMENTS BEING
APPLICABLE TO OTHER PURPOSES."
My Invention relates to improvements in the construction of incubators
In carrying out my Invention I employ a saddle shaped tank made of copper or
other suitable metal, whereby I am enabled to impart the requisite degree of heat
to the whole of the eggs. The boiler is jacketted and is connected to the tank, a
regular flow of hot water being obtained by means of return pipes, thereby heating
equally throughout. Two india rubber pipes or tubes connect the boiler with a
part of the incubator underneath the eggs, a perforated metal pipe being provided
whereby the steam of the boiler is used to moisten the eggs. The tank is connected
to a wooden frame with double sides and top, the space between being filled with
a suitable non-conducting material, the top of the tank is provided with any
suitable arrangement to ensure the apparatus being placed level.
The interior of the hereinbefore described wooden frame is divided in two parts.
In the top part I place the egg drawer and the hereinbefore described perforated
metal pipe for conveying moisture to the eggs, and is lined throughout with metal.
The egg drawer is made of metal, and has a perforated bottom and a sight hole.
The lower part is intended to be used either as a drying box for young chicks, or
for a lift, as hereinafter described, to act on the egg drawer.
The water in the tank is heated by means of a lamp of peculiar construction,
whereby I obtain an almost unvarying heat for a considerable time without the
lamp requiring trimming. The tube of this lamp is partly filled with cotton, and

page_text: the top part with pulverized asbestos as a conductor and wick for the volatile oil
(such as benzoline) burned in the lamp. The lamp stands on a lift which serves to
either raise or lower the lamp, the height of which is regulated by the handle of
the lift, which is connected to an indicator. This construction of lift I apply also
to the herein before described egg drawer if found desirable for large or small
incubators.
I also construct what I call "an artificial mother," which is constructed on the
same principle as the hereinbefore described tank, except that instead of it being of
the saddle form it is flat. It stands on four legs, and has a wooden rim to contain
non-conducting material on the top.
The hereinbefore described lamp may be used for other purposes, such as for
lighting railway carriages.

Ny Invention relates to improvements in the construction of incubators.
In carrying out my Invention I employ a saddle shaped tank made of copper or
other suitable metal, whereby I am enabled to impart the requisite degree of heat
to the whole of the eggs. The boiler is jacketted and is connected to the tank, a
regular flow of hot water being obtained by means of return pipes, thereby
heating equally throughout. Two india rubber pipes or tubes connect the boiler
with a part of the incubator underneath the eggs, a perforated metal pipe being
provided, whereby the steam of the boiler is used to moisten the eggs. "The tank
is connected to a wooden frame with double sides and top, the space between being
filled with a suitable non conducting material; the top of the tank is provided
with any suitable arrangement to ensure the apparatus being placed level.
The interior of the hereinbefore described wooden frame is divided in two parts.
In the top part I place the egg drawer and the herein before described perforated
metal pipe for conveying moisture to the eggs, and it is lined throughout with
metal. The egg drawer is made of metal, and has a perforated bottom and a
sight hole. The lower part is intended to be used either as a drying box for
young chicks, or for a lift, as hereinafter described, to act on the egg drawer.
The water in the tank is heated by means of a lamp of peculiar construction,
whereby I obtain an almost unvarying heat for a considerable time without the
lamp requiring trimming. The tube of this lamp is partly filled with cotton, and
the top part with pulverized asbestos or cotton wick as a conductor and wick for
the volatile oil (such as benzoline) burned in the lamp. The lamp stands on a
lift, which serves to either raise or lower the lamp, the height of which is regulated
by the handle of the lift, which is connected to an indicator. This construction
of lift I apply also to the hereinbefore described egg drawer, if found desirable, for
large or small incubators.
I also construct what I call "an artificial mother," which is constructed on the
same principle as the herein before described tank, except that instead of it being
of the saddle form it is flat. It stands on four legs, and has a wooden rim to contain
non-conducting material on the top.
The hereinbefore described lamp may be used for other purposes, such as for
lighting railway carriages.
But to make my Invention better understood, I will proceed to describe the
same by reference to the accompanying Drawing, in which Figure 1 is a front
elevation of my improved incubator; Figure 2 is a vertical section; and Figure 3
a back elevation of the same; Figure 4 is a similar view to Figure 1, with the front
slides removed; Figure 5 is a longitudinal section of the incubator, also shewing
my improved construction of lamp with lift applied thereto; Figures 6 and 7,
sectional views, shewing the "artificial mother" placed within a suitable coop;
Figures 8 and 9, front and plan views of the coop.
In Figures 1 to 5, a is the metal tank for imparting the requisite degree of heat
to the whole of the eggs; b is the boiler of suitable construction, surrounded by the
jacket c, and connected to the tank a by means of the return pipes d and e;
b¹, cover for the boiler; ƒ and g are the two india rubber pipes connecting the
boiler with the perforated metal pipe h in the part of the incubator underneath
the eggs; these pipes f, g, and h, convey steam from the boiler a for moistening
the eggs; j is the wooden frame with double sides and top, as shewn, the spaces
being filled with suitable non-conducting material; k is the drawer (made of metal

page_text: and provided with a perforated bottom) for containing the eggs, the said drawer k
being placed in the upper compartment i of the incubator, jimmediately over the
perforated metal pipe h. The compartment is lined throughout with metal m
or other suitable material, such as glass; is the lower compartment of the
incubator, which may be used as a drying box for young chicks, or to contain a
lift, as hereinafter described, for raising and lowering the egg drawer k; a¹, tube
for connecting the tank a with the outside air, and c' cover for the same; d, ther-
mometer for regulating the temperature in the compartment i; el, sight hole for
same; and g¹, alides for giving access to the interior of the incubator. A,
Figure 5, shews my improved construction of lamp, whereby I obtain an almost
unvarying degree of heat for a considerable time without the lamp requiring
trimming, n are the wick tubes of the lamp containing an inner tube o covered
with a cylindrical cotton wick p, and of shorter length than the tube n; q is the
asbestos or cotton wick in the top part of the tube n. It will be understood that
this improved lamp may be used for other purposes, such as for lighting railway
carriages, by modifying its construction; r is the lift, such lift consisting of a
platform, on which is placed the lamp; the said platform may be raised or
fowered by means of the handle s, which operates a roller over which passes a cord
passing over two other rollers, and connected to the platform; t, t, are stops for
fixing the platform at any desired height. This construction of lift may also be
used for raising and lowering the egg drawer k if found desirable.

My improved construction of "artificial mother" is shewn at B, in Figures 6
and 7. u is the tank of a flat shape, standing on the four legs v; wis the wooden
rim on the top of same, containing non-conducting material, such as sawdust; x is
the boiler; and y, z, return pipes for the tank u. Figures 6, 7, 8, and 9, shew a
coop suitable for containing the "artificial mother; h¹ is a suitable feeding
trough. The front, back, and sides of the lower part of this coop are glazed, and
the inside space so formed serves as a run for the young chickens, which enter the
same through a suitable hole in the coop; i, wire netting enclosing a space in
front of this hole.
Having thus described my said Invention, and the best means with which I am
acquainted for carrying the same into effect, I wish it to be understood that I do
not confine myself to the precise details of construction herein laid down and
shewn in the Drawing, as these may be varied without departing from the peculiar
character of my Invention, but what I do claim is,―
Firstly. The construction and employment of the improved incubator arranged
and operating substantially as herembefore described and represented in Figures 1
to 5 of the accompanying Drawing.
Secondly. The construction and employment in incubators of the lamp herein-
before described and shewn in Figure 5 of the accompanying Drawing, such lamp
being also applicable for other purposes.
Thirdly. The construction and employment of what I call an "artificial mother,"
substantially as hereinbefore described and represented in Figures 6 and 7 of the
accompanying Drawing.
In witness whereof, I, the said Marco Wilhelm Montauban-van-Swyndregt,
have hereto set my hand and seal, this Eighteenth day of June, in the year
of our Land One thousand sicht hundred and sight
