Improvements in Inou bators.

page_text: T PETER WALSH of Bourne Hall, Poulton-le-Fylde, in the County of
Lancaster, Farmer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to that class of incubators for hatching chickeus known as
the "Hearson" and similar apparatus, wherein a drawer is used for containing the
eggs to be hatched.
It has been the custom for the attendant to partially turn the eggs over by hand
about twice a day during the hatching period, so as to change the position of the
egg and present a fresh surface to the heat; and this has been found to be a slow
and imperfect process, especially when the attendant has some thousands of eggs to
look after.
My invention is designed to enable all the eggs (say about one hundred). in the
drawer to be turned part way round at one movement by mechanical means. For
this purpose I place a series of pairs of rods or bars at the bottom of the drawer
(which are mounted in suitable bearings) forming a bed for the eggs to lie upon, a
row of eggs being supported end to end by and between the two rods or bars of
each pair. The ends of these bars are provided with a suitable train of wheel gear,
whereby each pair is caused to revolve, and by preference alternately in the
opposite directions to the next pair by means of a winch handle which is placed on
the end of one of the bars at any convenient part, and turned by the attendant to
the desired extent at the required intervals of time.
Or instead of the winch handle the bars may be actuated by any suitable clock
work mechanism at intervals, whereby the eggs will be moved part way. round
automatically at certain given times.
Each pair of bars is preferably so far from the next pair as to allow rows of
the largest size of egg to be hatched, to be placed side by side in the drawer.

Improvements in Inou bators.
I, PETER WALSH of Bourne Hall, Poulton-le-Fylde, in the County of
Lancaster Farmer, 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 that class of incubators for hatching chickens known as
the "E. Hearson " and similar apparatus wherein a drawer is used for containing
the eggs to be hatched.

page_text: It has been the custom for the attendant to partially turn the eggs over by
hand about twice or thrice a day during the hatching period so as to change the
position of the eggs and present a fresh surface to the heat; and this has been
found to be a slow and imperfect process, especially when the attendant has some
thousands of eggs to look after.
My invention is designed to enable all the eggs (say about one hundred) in the
drawer to be turned partially round at one movement by mechanical means.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the annexed sheet of
drawings and the following explanation thereof.
Figure 1 on the drawings is a front elevation of the incubator with the
improved egg drawer shown in section;
Figure 2 is a plan view of the said egg drawer and
Figures 3, 4 and 5 are detached views of the details drawn to a larger scale.
a is the outside casing of the incubator.
b is the lamp and c the egg drawer.
For the purposes of my invention I place at or near the bottom of the egg
drawer c a series of pairs of rods or bars d which are mounted in suitable bearings
at each end, and at such a distance apart as to form a bed for the eggs d* to lie
upon, a row of eggs a being supported end to cud by and between the two rods or
bars of each pair, each pair of bars being arranged so. far from the next pair as to
allow rows of the largest size of eggs to be hatched, to be placed side by side in the
drawer.
The ends of these bars are provided with a train of wheel gear e whereby
cach pair is caused to revolve (by preference alternately) in the opposite
direction to the next pair as shown by the arrows by means of a winch handle f
(see Fig. 2) which is placed on the end of one of the bars at any convenient
part, and is turned by the attendant at the required intervals of time."
..
The toothed gearing e may be arranged as shown at Figs. 3 and 4, in which
case the wheels e will revolve in one direction and the intermediate wheels e¹
will revolve in the reverse direction, causing the rods d and d upon which the
eggs rest to rotate the eggs as shown at Fig. 3. the intermediate rods upon
which the eggs also rest being caused to revolve in the requisite direction by
the small pinious ex. In order however, to cause the last rod on the left to
evolve in the proper direction it will be necessary to have one additional small
pinion as shown at Fig. 4.
Or instead of this arrangement the toothed gear may be arranged as shown
nt Fig. 5. with only two small pinions by mounting oue set of wheels at one
end of every other rod, and a similar set of wheels at the other ends of the
intermediate rods all the wheels being the same size which will produce the
same effect, and the drawer can be reversed end for end, occasionally, or grooved
pulleys and endless bands may be employed to rotate the bars.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what i
claim is
.
In incubators of the class hereinbefore named providing the egg drawers with
a series of pairs of rods parallel to each other and at such a distance apart as
will support the eggs, such rods being fitted with toothed gear or equivalent
means whereby they can be made to rotate by a winch handle or otherwise so
as to cause all the eggs to be turned or partially turned simultaneously
substantially as herein before described and illustrated by the drawings annexed.
