PROVISIONAL SPECIFICATION.
Improvements in Surface Condensers Employed in connection with
Condensing Steam Engines.
1, JOSIAH RHODES, of Hope Foundry, Morley, near Leeds, in the County of
York, Machine Maker, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to create or enlarge the vacuum in the cylinder of
condensing steam engines, and this I propose to do by facilitating or quickening
the condensing of the exhaust steam within the pipes of the surface condensor,
which primarily consists of a series of steam pipes supplied with exhaust steam.
According to my invention I form a trough on the top series of pipes (or whole
series of pipes) of the surface condenser so that on water falling into the said
trough the water overflows and is more freely distributed than if the water fell
upon the round surface of the pipes, and I also form underneath each pipe a rib or
flange so that the water drips off the said rib on to the pipes underneath it.
By creating or enlarging the vacuum within the cylinder, the piston is greatly
assisted in its movement, requiring less steam to force the piston consequently there
is a saving in fuel.

COMPLETE SPECIFICATION.
Improvements in Surface Condensers Employed in connection with
Condensing Steam Engines.
I, JOSIAH RHODES, of Hope Foundry, Morley, near Leeds, in the County of
York, Machine Maker, 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 :-
The object of my invention is to create or enlarge the vacuum in the cylinders
of condensing steam engines, and this I propose to do by facilitating or quickening
the condensing of the exhaust steam within the pipes of the surface condensor,
which primarily consists of a series of steam pipes supplied with exhaust steam.
According to my invention I form a trough on the top series of pipes (or whole
series of pipes) of the surface condenser 50 that on water falling into the said
trough the water overflows and is more freely distributed than if the water fell
upon the round surface of the pipes, and I also form underneath each pipo a rib er
flange so that the water drips off the said rib on to the pipes underneath it.
In order that my invention may be better understood 1 will make reference to
the accompanying sheet of drawings, wherein
Figs. 1 and 2 illustrate au arrangement of pipes comprising a surface condenser

page_text: through which exhaust steam passes from the cylinder of a condensing steam engine.
According to my invention I form troughs A on the top series of pipe B but the
said trough A may be formed on all the pipes if required. I also form a rib C
underneath each pipe so that when cold water falls through perforations D in
pipe E the troughs A fill with water and on overflowing falls from the surface of
the upper series of pipes and drops off the rib or flange C on to the pipe or pipes
underneath consequently by my invention the cold water impinges against the whole
of the outer surface of each pipe whereby the exhaust steam passing through the
pipes
pipes A is fully condensed, and water produced thereby is comparatively cold before
being re-used by the steam engine, consequently a larger vacuum is created in the
cylinder of the engine which greatly assists the piston in its movement requiring
less steam to operate some consequently there is a saving of fuel.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. The formation of troughs A in the pipes of surface condensers employed
in connection with condensing steam engines as shewn and described.
Secondly. The formation of troughs A and ribs C in the pipes of surface
condensers employed in connection with condensing steam engines in manner shewo
and for purposes set forth.
