PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Heating Feed Water or other
Liquids, and in Apparatus therefor.
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:-
In my Specification No. 192221 I set forth an apparatus for use as a feed make
up evaporator. I have since found that this mechanism with comparatively little
alteration can be made very useful for ordinary feed heating purposes and this
application is designed for the purpose of covering the application of the principle
set forth in that invention to feed heating.
In carrying out my invention for this purpose I provide as in my before
mentioned Patent, an outer casing with a hollow hinged door having two com-
partments separated from each other. On this hinged door with their two ends
entering respectively the two apartments I fix a series of bent tubes preferably so
arranged that when the door is shut they shall be tolerably evenly distributed
through the chamber but allowing space for a float to rise & fall. The feed water
to be heated passes through the apparatus and among these pipes, steam, the products
of combustion or other heating Huid being passed through the pipes to heat it.
By means of a ball or float valve or equivalent apparatus the air and floating grease
and deleterious matters are automatically blown off at intervals. It will be obvious
that this device can be applied for heating other liquids besides feed water.
that the positions of the feed water and heating fluid could be reversed.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Heating Feed Water or other
Liquids, and in Apparatus therefor.
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:-
In my Patent Specification No. 19222", I set forth an apparatus to use as a feed
make up evaporator.
I have since found that this mechanism, with comparatively
little alteration, can be made very useful for ordinary feed heating purposes, and
this application is designed for the purpose of covering the application of the
principle set forth in that invention to feed heating.
In carrying out my invention for this purpose, I provide, as in my before
mentioned Patent, an outer casing with a hollow hinged door having two com-
partments separated from each other. On this hinged door, with their two ends
entering respectively the two apartments, I fix a series of bent tubes preferably so
arranged that, when the door is shut, they shall be tolerably evenly distributed
through the chamber. The feed water to be heated passes through this apparatus
and among these pipes, the products of combustion or other heating fluid being
passed through the pipes to heat it. By means of a ball or float valve or equivalent
apparatus, the air and floating grease and deleterious matters are automatially blown

liquids besides feed water.
The drawing is a sectional elevation of an apparatus designed by me.
In this―
a is the lower casting:

c the tube plate:
d
the door, and f the hinge, all substantially as in my patent evaporators
No. 1922291:
e cavity in door, which is divided into two compartments:
g is the inlet for the feed water, which falls down the smaller cavity of the main
body of the apparatus h, and, after passing amongst the heating surface b, rises up
the larger cavity i to the outlet k. Air and grease rise to the surface of the water
into the cap o, and are automatically discharged by the ball valve and ball m,
through the outlet n. The cavity e of the door is divided by a partition, not shown
on the drawing, into two parts; into one part the heating fluid aud one end of tubes b
enter, from the other compartment the exhausted heating fluid exits, and into this
compartment the other ends of the tubes benter.
The mode of action is as follows:-
:-
The heating fluid entering one half of chamber e passes through the heating
tubes to the other half of chamber e, and from there escapes to the chimney or
other destination, heating the feed water in chamber a.
It will be obvious that the positions of the feed water and heating fluid could be
reversed.
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 application and adaptation of my patent apparatus No. 192221 for the
purpose of feed heating, substantially as herein described.
2. In a feed water heater, the hanging of the heating surface upon a hinge in such
manner that, on the breaking of the joint, it can be opened out for cleaning and
examination without disturbing the relative positions of its parts.
3. The combination, in a feed heating apparatus, of a heating surface that can be
withdrawn bodily from the shell by means of a hinge without disturbing the relative
positions of its parts, substantially as described, with automatic arrangements for
blowing off the air and grease from the water or other fluid that is being heated in
passing through, whereby a feed heating apparatus is formed requiring very little
attention and capable of being very easily and quickly examined, cleaned and
repaired.
