PROVISIONAL SPECIFICATION.
Improvements in Condensers.
I, THOMAS MUDD of The Central Marine Engine Works, West Hartlepool, in
the County of Durham, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention is based to a considerable extent on the same principle as that set
forth in my Patent No. 19222º1. I have found that a very similar apparatus can
be applied to the condensing of fresh water from steam with very great advantage,
the main difference being that what is heating surface in my said Patent No. 1922291
is cooling surface in this Patent. I prefer however in this instance to always place
the hinge of the door at the side and not at the top, as by this means the bent tubes
will lie in such a position as to keep these well drained.
The apparatus in other respects can be made similar to that set forth in my
aforesaid Patent.

COMPLETE SPECIFICATION.
Improvements in Condensers.
I, THOMAS MUDD, of The Central Marine Engine Works, West Hartlepool, in
the County of Durham, Engineer, 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 is based to a considerable extent on the same principle as that set
forth in Patent No. 19222". I have found that a very similar apparatus can be
applied to the condensing of fresh water from steam with very great advantage, the
main difference being that what is heating surface in my said Patent No. 19222"
is cooling surface in this Patent. I prefer, however, with condensers, to place the
hinge of the door at the side and not at the top, as by this means the bent tubes
will lie in such a position as will keep them well drained, whereas, if suspended
from the top, the water would accumulate in the bend.
The apparatus is best described by aid of the accompanying drawing which
represents a sectional plan of my apparatus.
In this A is the shell or outer envelope, containing the cold water of circulation:
B is the cooling surface arranged in any desirable form of straight or coiled tubes,
or even of narrow flat stayed pockets or compartments, it will be hereafter spoken
of as the tubes. C is the tube plate to which the tubes are attached: E a chamber
of which the tube plate forms one side. The tubes are so arranged that the fluid
to be condensed can enter them from the upper part of this chamber, and leave
them again to enter the lower part of this chamber. F is the hinge to which the
chamber E with its tube plate and tubes is fixed and D and G two flanges which,
when the door is closed, about against each other and can form a joint by means of
red lead or other material. When the door is closed, therefore, the tubes B are
inside the condensing chamber or shell A. By hanging the cooking surface upon
the hinge F, the apparatus can be very easily opened for cleaning purposes.
steam enters the chamber E by a branch near the top, and the condensed water
leaves the chamber E by another branch entering it at the bottom, which is not

circulating water. Z shows the position of the bunker, by which it will be seen
that the condenser can be easily fixed against the bunker corner in the ship or in
any other similar position.
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 :-
1. The improvement or modification of my Patented invention No. 19222" or
parts thereof, so as to adapt it for condensing purposes, substantially as herein
described.
2. The arrangement, in condensers, of the cooling surfaces hanging upon a hinge,
preferably horizontal, so as to facilitate the operation of cleaning and examination.
3. The general construction and arrangement of condensers, substantially as
herein described and illustrated.
