PROVISIONAL SPECIFICATION.
Improvements in Feed Water Heater and Condensing Apparatus.
I, Sir EDWARD GREEN, Baronet, of the Firm E. Green and Son Ld. of
Wakefield, in the County of York, Fuel Economiser Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in feed water heater and condensing
apparatus the object being to construct a heater from a series of tubes in com-
bination with end covers having holes of different diameters, and enclosing same in
jacket which may or may not be surrounded by a casing to form an extra steam
chamber in addition to the tubes, these being so arranged in the water portion that
a free circulation of steam (preferably exhaust) can be obtained. The water also
has a free circulation.
To carry my invention into practice, I arrange a nest of tubes having different
sized ends in plates which I fix to a jacket for support upon rings or brackets of an
outer casing. I form a chamber under and another above the tubes to allow of
free access and passage of steam through the tubes, as well as through the space
between the two jackets, if two be used.
The water to be heated flows slowly through the apparatus, and its speed can be
regulated, as desired.
The apparatus as above constructed will also answer as a water surface
condenser.

Improvements in Feed Water Heater and Condensing Apparatus.
I, Sir EDWARD GREEN, Baronet of the Firm E. Green and Son Ld. of
Wakefield in the County of York, Fuel Economiser Manufacturer, 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 to feed water heaters and condensing apparatus, the
object being to construct a heater from a series of tubes in combination with end
covers having holes of different diameters and enclosing same in jacket which may
or may not be surrounded by a casing to form an extra steam chamber in addition
to the tubes, these being so arranged in the water portion that a free circulation of
steam (preferably exhaust) can be obtained, the water also has a free circulation.
To carry my invention into practice, I arrange a nest of tubes having different
sized ends in plates which I fix to a jacket for support upon rings or brackets of an
outer casing, I form a chamber under, and another above the tubes to allow of free

page_text: access and passage of steam through the tubes as well as through the space between
the two jackets, if two be used.
The water to be heated flows slowly through the apparatus, and its speed can be
regulated, as desired.
The apparatus as above constructed will also answer as a water surface
condenser.
The annexed drawings will enable my invention to be clearly understood.
Figure 1 a vertical section.
Figure 2 a plan from the top of the upper box.
A, B, lower and upper boxes respectively for water. C, C, tubes connecting
said boxes. D, D, stool like frame supporting same. E water inlet pipe.
F junction connecting said pipe E with box A. G junction connecting box B
with water exit pipe H. J steam inlet. K steam vapour exit. L casing in
which steam has free play around both boxes A, B, tubes C, C, junctions F, G,
and the descending branch M of the water inlet pipe E. N, N, are lids or covers
of the upper box B through which the tubes C, C, can be inserted for location in
the boxes, as indicated.
The boxes A, B, may each be in a single casting, or composed of a series of.
castings capable of being bolted or braced together for the attachment of the
junctions.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A water heater composed of boxes A, B, tubes C, C, lids N, N, junctions F, G,
support D, water inlet branch M enclosed in a casing L in which steam has free
entry and exit, as set forth and substantially as shown.
2. In a water heater, the combination of boxes A, B, tubes C, C, junctions F, G,
lids N, N, stool D, D, casing L arranged and acting in the manner substantially as
described and represented.
