Improvements in Feed Water Heaters and the like.
We, JOHN GEORGE CHAMBERLAIN and RALPH PLAYER, trading as Joseph
Wright and Company, of Tipton, in the County of Stafford, and of 124, Victoria
Street, in the City of Westminster, Engineers, and JAMES RADCLIFFE,. Engineer.
to the said Joseph Wright and Company, do hereby declare. the nature of this
invention to be as follows:-
This invention relates more especially to heaters of the character generally
known as Berryman heaters, and it has for its object to provide a heater which
is simple and economical in construction, and which will allow of being inspected,
repaired, and cleaned, without disconnecting any pipes, or removing the outer
casing, whilst grease is also intercepted and can be readily removed. According
to this invention there is provided a casting which is mounted upon suitable
supports, or legs, and supports the tubes and the casing in which they are
enclosed. The said casting is made with inclined tube plates at opposite sides
of its interior there being between each of the said tube plates and the sides of
the outer sides of the casting a space forming a chamber at each side into one of
which the exhaust steam or other heating medium enters, it then passing through
the said tubes towards the opposite chamber from which chamber, as well as from
the first chamber, the water of condensation is drawn when steam is used as, the
heating medium. Each of the said chambers has, at bottom, an opening covered
by a door, or cover, so that by removing these the tube ends can be expanded into
the tube plates and the interiors of the tubes can be readily cleaned. Grease is
also intercepted by the first of these chambers and can be removed through the
said opening at intervals. The water or other liquid which is to be heated is
fed in through a pipe connection in the said casting opening into the space
between the tube plates and the heated liquid is withdrawn by a pipe passing
upwards from a pipe connection also in the said casting the said pipe preferably
having its upper end turned down so as to prevent scum being drawn off with
the liquid. In the said casting there is also an opening below the space between
the tube plates so that by removing a door, or cover, which normally, closes this,
access to the exteriors of the tubes and interior of the casing can be obtained.

We, JOHN GEORGE CHAMBERLAIN and RALPH PLAYER, trading as Joseph
Wright and Company, of Tipton, in the County of Stafford, and of 124, Victoria
Street, in the City of Westminster, Engineers, and JAMES RADCLIFFE, Engineer
to the said Joseph Wright and Company, 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 relates, more especially, to heaters of the character generally
known as Berryman heaters, and it has for its object to provide a heater which
is simple and economical in construction, and which will allow of being inspected,
repaired, and cleaned, without disconnecting any pipes, or removing the outer casing,
whilst grease is also intercepted and can be readily removed. We will describe
this invention with reference to the accompanying drawing, wherein Figures 1
and 2 are elevations, (half in section), at right angles to each other, and Figures 3
and 4 are horizontal sections, (respectively taken on the lines 3, 3, Figure 1, and
4, 4, Figure 2), of a heater constructed according to this invention. The
casting A, is mounted upon supports, or legs, B, the said casting supporting the
-tubes. C, and casing 1), in which they are enclosed. The said casting A, is made
with inclined tube-plates-a, -a, at opposite sides of its interior, there being,
between each of the said tube plates, and the interior of the outer sides of the
casting A, a space forming a chamber at each side, (these chambers -are-
marked a² a respectively), into one of which spaces exhaust steam, or other
heating medium, enters, by an inlet pipe attached at a', it then passing through
the said tubes C, towards the opposite chamber, from which chamber, as well as
from the first chamber, the water of condensation is drawn, when steam-is-used-as
the heating medium. An exit pipe for escaping heating medium is connected
at ab. Each of the said chambers a², a, has, at bottom, an opening f, covered
by a door, or cover, f, so that; by removing these doors, or covers, the tubes can
be expanded into the tube-plates and the interiors of the tubes can be readily
cleaned. Grease is also intercepted by the first of these chambers (a2), and can be
removed through the opening f, therefrom at intervals. The water, or other
liquid, which is to be heated, is fed in through a pipe connected at g, to the said
casting, and opening into the space between the tube plates, and the heated liquid
is withdrawn by a pipe h, passing upwards from an opening in the said casting
at h², to which is connected the outlet pipe for the said water, or liquid. The
said pipe h, may have its upper end turned down, as shewn, if desired, so as to
prevent scum being drawn off with the liquid, but this is not essential. In the
said casting there is also an opening, at i, below the space between the tube
plates, so that, by removing a door, or cover, 22, which normally closes this
opening i, access can be obtained to the exteriors of the tubes and interior of the
casing D. J is a cock for removing the sludge and emptying out the water, or
other liquid, when required.
Having now particularly described and ascertained the nature of this inven-
fion and in what manner the same is to be performed, we declare that what wẹ
claim is:-
1. A heater, for heating feed water, or the like, constructed substantially as
herein before described, and illustrated in the accompanying drawing.
2. In heaters, for heating feed water, or the like, a casting having chambers,
at each side, into which the respective tubes open, and openings, beneath the

page_text: said chambers, closed by doors, or covers, so that, by removing these, access can
be had to the said chambers and to the tube ends; substantially as herein before
described and illustrated in the accompanying drawing.
3. In heaters, for heating feed water, or the like, a casting having chambers,
at each side, into which the respective ends of the tubes open, and openings
beneath the said chambers, and also an opening beneath the space between the
tube-plates, the said openings being closed by covers, or doors, so that, by re-
moving these, access can be had to the said chambers, and to the tube ends, and
also to the exteriors of the tubes, and the interior of the casing; substantially
as herein before described and illustrated in the accompanying drawing.
Dated this 24th day of November 1899.
