Improvements in Incubators.
Year: 1899

page_text: ARTHUR FRANCIS PATERSON, of Birkwood, Banchory, Kincardineshire, Gentle-
man, do hereby declare the nature of this invention to be as follows:-
This invention relates to incubators and has for its object to improve their
construction, whereby they may be cheapened and rendered more interesting and
easy to work.
To this end I construct a wooden case, of fair height in the mid-line, having a
wide roof sloping downwards to the sides; thus, in general appearance, resembling
a cottage.
The inside is lined with metal.
In conjunction with this I have a vertical tank of peculiar construction, very
much deeper than broad, which, closely approximating to the top and bottom of
case, splits the capacity of the chamber into two side halves. (This tank may
be conveniently made of tin or other metal and heated by hot air.)
Right and left of this tank are trays for the reception of eggs.
This chamber being illumined by the lamp, or other heat-generator, and the
tank conveniently V-shaped, or otherwise, the operator, through the lamp-door
at one extremity or through the glass-damper at top of the machine, is afforded
a clear and uninterrupted view of all the eggs and thermometers, without any
reduction in temperature such as is occasioned by general methods. Also, the
two sides of the roof being hinged, every part of the machine is within touch and
view of the said operator.

Improvements in Incubators.
ARTHUR FRANCIS PATERSON, of Birkwood, Banchory, Kincardineshire, Gentle-
man, 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 incubators and has for its object to improve their
construction whereby they may be cheapened and more successfully worked.
The invention is illustrated by the accompanying drawings. Fig. 1 is a
perspective view of the improved incubator. Fig. 3 a vertical section of same
and Fig. 2 a section of tank showing the course of the hot air.

page_text: The incubator comprises a box A having a wide roof sloping downwards to the
sides. The inside is lined with bright tin (Fig. 3, J). In conjunction with this
I have a V-shaped vertical tank C, very much deeper than broad and of almost.
equal length with box, which approximating to the top and bottom of case, splits
the capacity of the chamber into two side halves.
Right and left of this are trays H, H, for the reception of eggs. These are
made removable.
The construction of the tank C, and the course of the heated air through it
is illustrated fully by Fig. 2. K (Fig. 3) is a wooden support and L, L, moveable
arms whereby the tank is kept in, and released from, an upright position.
The moisture is supplied by ordinary damp pans I, I, (Fig. 3). Fresh air is
introduced at N, N, (Fig. 1) and M (Fig 1). The regulation of heat is by an
ordinary expanding capsule which rests on a bracket at one end of tank. This
capsule, by means of a .connecting upright rod, acts on, the lever G, which, by
raising the damper F, uncovers the valve hole beneath. D is the lamp: B. is
the stand: E is the chimney.
The chamber being illumined by the lamp, the operator through the glass
damper F is afforded a clear and uninterrupted view of all the eggs, and ther-
mometers without that reduction in temperature occasioned by general methods.
Also, the two sides of the roof being hinged, every part of the machine is within
touch and view of the said operator.
;
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
, יו*
:
An incubator having the capacity of its chamber split into two side halves
by a vertical tank.
Dated this the 26th day of April 1900.
