PROVISIONAL SPECIFICATION.
Improvements in Fluid Heaters or Condensers.
I, JAMES ATKINSON, of The Woodlands, Marple, Cheshire, Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is the improvement of what is known as Atkinson's
feed water heater for which Letters Patent No. 2458 A.D. 1877, were granted,
and is mainly for the purpose of making them more suitable for the higher
pressures now more commonly carried in steam boilers, to give greater security in
making the necessary joints and connections, and to give increased facilities for
cleaning them out:
In the improved heater the tube plate is formed in the shape of an inverted V,
or is arched upwards, and is cast in one with a cylindrical casting forming the base.
This casting is of such a form that the exhaust steam can pass underneath the tube
plate, parallel to its ridge, and the pockets formed on the upper side of the tube
plate between it and the cylindrical portion of the casting enable the cleaning ont
openings and the connections for the water inlet and blow out to be formed in
the casting itself,instead of in the wrought iron shell, as has been hitherto done. The
tube plate is strengthened by ribs on its under side placed at right angles to the
ridge thus transmitting the heavy pressure on the upper side in such a manner that
these strains largely neutralize each other, or are conveniently transmitted to the
cylindrical portion of the main casting. Openings are cast in these ribs for the
free passage of the exhaust steam. The small circulating tubes at their lower ends
are conveniently attached to the ribs, thus preventing the necessity for the sharp
bends hitherto required in them.
The improved apparatus may be used for heating any kind of fluid or as a
condenser.

Improvements in Fluid Heaters or Condensers.
I, JAMES ATKINSON, of The Woodlands, Marple, Cheshire, 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 :-
The object of this invention is the improvement of what is known as Atkinson's
feed water heater for which Letters Patent No. 2458 A.D. 1877 were granted, and
is mainly for the purpose of making them more suitable for the higher pressures
now more commonly carried in steam boilers, to give greater security in making
the necessary joints and connections and to give increased facilities for cleaning
them out.
To enable this invention to be clearly understood I append one sheet of drawings
in which Fig. 1. is a sectional plan, Fig. 2. is a vertical section of the lower part,
and Fig. 3. is a vertical complete section at right angles to Fig. 2.

page_text: In the improved heater the tube plate A is formed in the shape of an inverted V
or is arched upwards and is cast in one with a cylindrical casting forming the base.
This casting is of such a form that the exhaust steam can pass underneath the tube
plate A parallel to its ridge, in the direction shown by arrows and the pockets BB
formed on the upper side of the tube plate A between it and the cylindrical
portion of the casting form places where deposit can settle and enable the
cleaning out openings C, C, the connection D for the water inlet and the blow
out E to be formed in the casting itself instead of in the wrought iron shell as has
hitherto been done.
The tube plate A is strengthened by ribs F on its under side placed at right
angles to the ridge, thus transmitting the heavy pressure on the upper side in such
a manner that these strains largely neutralize each other, or are conveniently
transmitted to the cylindrical portion of the main casting. Openings G are cast
in these ribs for the free passage of the exhaust steam. The small circulating
tubes H at their lower ends are conveniently attached to the ribs F thus preventing
the necessity for the sharp bends hitherto required in them.
The improved apparatus may be used for heating any kind of fluid or as a
condenser.
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 general arrangement and construction of a fluid heater or condenser
having tubes open to the steam at their lower ends, closed at their upper ends and
having smaller internal circulating tubes open top and bottom, the large tubes being
fixed in a tube plate of an arched or inverted V form, this tube plate being a
portion of a main casting of such a form that its cylindrical portion strengthens the
tube plate which is connected to it by means of transverse ribs on its lower side
which have openings for the passage of the exhaust steam, as described and
illustrated.
2. The general arrangement and construction of a fluid heater or condenser as
described in Claim 1 having pockets B B for the collection of deposit and having
openings for cleaning, also openings for the passage of the fluid to be heated
formed in the main casting on which suitable substantial provision is made for the
joints, as described and illustrated.
3. The general arrangement and construction of fluid heaters and condensers as
described in the specification and illustrated in Figs. 1. 2 and 3. of the drawings.
