provided with openings for the admission and exit of water to be heated. These
openings enter the heater at its lower end the domed cover of which is likewise
provided with a division plate corresponding to that in the body of the heater.
A tube plate intervenes between the heater and its lower cover into which the
ends of certain pipe coils are fitted by screwed and socketted joints. These pipe
coils traverse the body of the heater and are then connected up to the opposite
end of the division plate aforesaid by a special joint from which point the pipes
descend on the opposite side of the division plate to the opposite half of the tube
plate whence the steam finds egress through an outlet on the domed cover.
By
this means for the same height of apparatus a double period of contact between
water and hot pipes is effected.
The water is thus caused to enter the heater to pass thereup and to descend on
its opposite side around the pipe coils within which the steam is circulating.
The jointing of the pipes I effect by screwing down or forcing a conical female
union onto a metallic ring let into a groove formed on the outside of the conical
male nipple which ensures a tight and reliable joint.
For preventing the choking of the steam pipe coils I provide a special dirt
arrester consisting of a perforated plate or copper mesh which I place between the
Hanges of contiguous pipes or a short cylinder the inner edges of which may be
fined off to form a receptacle or chamber for the dirt which can be readily removed
by taking out the pipe or cylinder. This device is fitted at the entry to the heater.
At the upper end of the heater where the water passes over the end of the
division plate I provide means by cocks suitably arranged and situated for the
outlet or extraction of the air and grease in the feed water which collect here and
and are extracted instead of being subsequently passed on to the boiler.
A special air chamber is provided for the purpose which may conveniently be put
in connection with the hot well. Access doors for repairs and cleansing are
arranged preferably in line with the water inlet and outlets towards the base of
the heater where also a bye-pass may be provided with valves and pipes so arranged
that if an accident was to happen to the heater the feed-might be transferred
lirect to the boiler.
As will be understood the special steam tight jointing herein foreshadowed as
well as the device for arresting the dirt conveyed by steam in transit are meant
to be applicable to all cases of analogous natures in heaters, condensers, distillers,
evaporators and the like.

COMPLETE SPECIFICATION.
Improvements in or connected with Feed Water Heaters,
Condensers, Distillers, Evaporators, and the like.
I JOSEPH REED of 3 Prudhoe Terrace North Shields in the County of
Northumberland 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 relates to improvements in or connected with feed water heaters,
condensers, distillers, evaporators and the like, and consists in a special arrange-
ment or combination of parts having for its objects simplicity of design and
efficiency of action.
To effect my purpose I make use of an external shell or cylinder of
suitable size and shape both ends of which are designed to take a cover as shown
in section on Sheets I and 3. A division plate marked D on Sheet I also Sheet 3
traverses the interior of the chamber or shell which is likewise provided with
openings marked E, E¹ on Sheet I also Sheet 3 for the admission and exit of water
to be heated. These openings enter the heater at its lower end.
The domed cover marked A on Sheet I also Sheet 3 is likewise provided with a
division plate corresponding to that in the body of the heater and is shewn, in
section où Sheet 3 and marked D.
A tube plate intervenes between the heater and its lower cover into which the
ends of certain pipe coils traverse the body of the heater (the tube plate and
manner of fixing the coils are shewn on Sheet 3 and marked T) and are then
connected up to the opposite end of the division plate aforesaid marked Don
Sheet 3 by a special joint as shewn on Sheet II and marked Fig. II from which
point the pipes descend on the opposite side of the division plate to the opposite
half of the tube plate as shewn on Sheet 3 and marked C wlience the steam finds
egress through an outlet marked o on Sheet 3 on the domed cover marked A on
Sheets and 3.
By this means. for the same height of apparatus a double period of contact
between water and hot pipes is effected. The water is thus caused to enter the
heater to pass thereup and to descend on its opposite side around the pipe coils
within which the steam is circulated.
The jointing of the pipes I effect by screwing down or forcing a conical female
union onto a metallic ring let into a groove formed on the outside of the conical
male nipple which ensures a tight and reliable joint. This arrangement of joint
is illustrated on Sheet II and marked Fig. II the metallic ring is marked M on the
Fig. II Sheet II.
For preventing the choking of the steam coils I provide a special dirt arrester
consisting of a perforated plate or copper mesh which I place between the flanges
marked Fig. III Sheet II of contiguous pipes or a short cylinder marked S
Fig. III Sheet II the inner edges of which may be filed off to form a receptacle or
chamber for the dirt which can be readily removed by taking out the pipe
or cylinder. This device is fitted at the entry to the heater and is marked E3³ on
Sheet 3 of the drawings.
At the upper end of the heater where the water passes over the end of the
division plate and marked L on Sheet 3 of the drawings I provide means by
cocks suitably arranged and situated for the outlet or extraction of the air and
grease in the feed water which collects here marked B on Sheet 3 of the drawings
and are extracted instead of being subsequently passed on to the boiler.
A special air chamber marked H on Sheet 3 is provided for the purpose which
may conveniently be put in connection with the hot well.
Access doors for repairs and cleansing are arranged preferably in line with the
water inlet and outlets towards the base of the heater where also a bye pass marked

ipes so arranged that if an accident was to happen to the heater the feed might.
be transferred direct to the boiler.
.
As will be understood the special steam tight joint Fig. II Sheet II herein
oreshadowed as well as the device for arresting the dirt marked Fig. III on
Sheet II of the drawings conveyed by steam in transit are meant to be applicable to-
ll cases of analogous natures in heaters, condensers distillers evaporators and the
ike.

how fixed and secured.
On Sheet II Fig. III is shewn the form of dirt arrester as herein described.
On Sheet II Fig. II is shewn the form of adjustable metallic joint coupling.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. This particular form of apparatus with partition plate dividing it length-
wise and the inlet and outlet branches opposite each other and on the same
horizontal plane as shewn on Sheet I and 3.
2nd. The form of bye pass valve arrangement shewn on Sheets 1 & 3 and
marked Fig. I.
3rd. The adjustable metallic coupling as shewn on Sheet II Fig. II.
