COMPLETE SPECIFICATION.
Improvements in Steam Engines Fitted with "Jet" Condensers.
I, ALFRED AUSTIN RICKABY, of Bloomfield Engine Works, Sunderland, in
the County of Durham, Engineer, do hereby declare the nature of said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of my invention is to enable the injection water to be continuously
used for condensing by causing it to pass, on issuing from the air pump in a heated
state, through an apparatus in which it is exposed to surfaces kept at the tempera-
ture of the atmosphere by flowing water.
It is specially adapted to colliery and other land engines in which impure water
has frequently to be used for injection causing serious fouling of the condenser and
air pump as such water being used over and over again becomes pure by depositing
the solid matter it contains.
In very many cases, especially at collieries, a plentiful supply of cold water is
available for the cooling apparatus which may be of any suitable construction but
will be preferably with tubes through, or outside of, which the heated injection
water will be passed either direct or in a sufficient number of courses to impart its
heat to the cold surfaces of the tubes the opposite surfaces of which are in contact
with the cold water constantly flowing over, or through them. Feed water for the
boilers will be taken as usual from a hot well attached to the air pump before the
main portion of the injection water passes to the apparatus.
As the cooling apparatus may be constructed in various forms according to the
onditions in each case I have not thought it necessary to file any drawings. In
ne form it may consist of a vessel containing a number of tubes through which, or
[Price 4d.]

page_text: around which, the heated injection water may pass in one or more courses in
contact with surfaces cooled by cold water flowing through or around the tubes.
In another form where space is available the heated injection water may pass
through or around a number of cellular channels in contact with surfaces cooled
by cold water flowing through or around such cellular channels.
In any arrangement of the apparatus means of access will be provided for the
purpose of cleaning and removing any sediment deposited by the injection water in
its first series of passages through the cooling process.
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 :-
The application to steam engines with jet condensers of an apparatus in which
the heated injection water, as leaves the air pump, may be cooled by flowing in
one or more courses in contact with surfaces having cold water continuously flowing
over the opposite sides of such surfaces as hereinbefore described and with the
objects specified.
