PROVISIONAL SPECIFICATION.
Improvements in Explosion Engines.
We, WILLIAM HORNSBY and ROBERT EDWARDS, both of Spittlegate Iron
Works, Grantham, in the County of Lincoln, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in cooling water for engines worked by
the explosion of gas or other combustible vapour and air, where it is necessary to
cool the cylinder.
In carrying out our invention we provide the cylinder with a water jacket
through which water is circulated as is usual in such cases, and the water as it
leaves the jacket is caused to fall or run in a series of thin streams down vertical
plates or boards or on a series of obstructions which may for example be in the
shape of bars, the same being contained in a chamber through which a current of
air is then circulated in the same or opposite direction to that in which the water
flows or runs down, the circulation of the air being advantageously caused by the
action of a blast of the exhaust gases of the cylinder acting in a suitable chimney
or outlet, which chimney or outlet is connected to the said air space through which
the water passes.

We, WILLIAM HORNSBY and ROBERT EDWARDS, both of Spittlegate Iron
Works, Grantham, in the County of Lincoln, Engineers, do hereby declare the
nature of this invention and in what inanuer the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to improvements in cooling water for engines worked by
the explosion of gas or other combustible vapour and air, where it is necessary
to cool the cylinder.
In carrying out our invention we provide the cylinder with a water-jacket
through which water is circulated as is usual in such cases, and the water as it leaves
the jacket is caused to fall or run in a series of thin streams down vertical plates or
boards or on a series of obstructions which may, for example, be in the shape of
bars, the same being contained in a chamber through which a current of air is then
circulated in the same or opposite direction to that in which the water flows or runs
down, the circulation of the air being advantageously caused by the action of a
blast of the exhaust gases of the cylinder acting in a suitable chimney or outlet,
which chimney or outlet is connected to the said air-space through which the
water passes.

page_text: To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :—
Figure 1 is a vertical section of an apparatus embodying our invention; and,
Figure 2 is a plan of the same :
a is the chamber having at the upper part a chimney or shaft b into which the
exhaust pipe c from the engine enters and having at the lower part a series of
openings or apertures d, d so arranged that when the exhaust is entering the
chimney a current of air will be induced through the chamber, the air entering
through the apertures d, d and escaping through the chimney.
e, e indicate a series of pipes which enter the chamber at the upper part and are
connected to the pipe g communicating with the jacket of the engine cylin ler, the
said pipes e, e being perforated on their lower sides. f, fare a series of boards or
plates located vertically beneath the pipes e, e and so arranged that as the heated
water issues from the perforations in the said pipes e, e it will flow down the said
boards in thin films or streams, whereby it will come into immediate contact with
the current of air passing through the chamber in the opposite direction, the cool
water falling into the bottom of the chamber whence it is withdrawn by the pump
in the usual manner and again passed through the cylinder jacket..
We do not confine ourselves to the use of vertical plates or boards as in some
cases we may prefer to employ a number of cross-bars or obstructions, the water
being allowed to drop or fall from one to the other. We may also make the
chamber a of any desired shape and instead of arranging the bottom of the same to
form a tank we may employ an independent tank beneath the chamber which in
this case is open at the bottom, thereby rendering the air holes d, d unnecessary.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination with the jacketted cylinder of an explosion engine, of a
practically closed chamber through which a draught is induced, the said chamber
having within it a series of vertical plates or boards, or a series of strips, cross-bars
or other obstructions down or over which the heated water from the cylinder jacket
is caused to flow, substantially as, and for the purpose, described.
2. A water cooling apparatus for an explosion engine comprising a chamber
having a chimney or funnel at its upper part into which the products of combustion
exhausted from the engine cylinder are introduced and near the bottom a series of
openings for the admission of air, the said openings being placed in such a position
that the lowermost part of the chamber will form a tank, and a series of vertical
boards or plates down which the heated water flowing from the cylinder jacket is
caused to flow substantially as herein before described and illustrated in the
accompanying drawing.
