page_text: Improvements in Water Heaters Condensers and Separators.
We, DAVID MEIN NESBIT, Engineer, and WALTER CLOWES, Engineer, both of
12, Great James Street, Bedford Row, London, W.C., do hereby declare the nature
of this invention to be as follows:-
This invention has reference to improvements in connection with water heaters,
the object being to provide in one compact apparatus a separator for removing
the grease and impurities from steam which is to pass through the heating appara-
tus and coils, and a heater or condenser, through which the exhaust steam shall
pass.
In carrying the invention into effect we arrange an outer grease chamber,
separator, jacket or casing to enclose or surround an ordinary heater body, the
interior portion of which heater body contains the series of bent or other heating
pipes arranged in any well known manner, although we find it particularly advan
tageous to employ the arrangement of pipes and fittings as set forth in our Appli-
cation for Patent No. 21020 of 1897, and we are able to employ steam of a
pressure less than that of our atmosphere.
The grease chamber or separator which we employ to receive the exhaust steame
from the engine or other motor we arrange with a series of diaphragms or ribs
about its inner periphery and we form also when possible a number of like ribs
or baffle plates upon the exterior periphery of the heater casing, the object being
to ensure that the exhaust steam on its entrance into the separator chamber shall
be compelled to follow a tortuous path and thus to be spread up and the grease to
be deposited or caused to fall to the lower portion of the chamber, while the outlet
branch we arrange on the opposite side of the grease chamber preferably on a
different level to that of the inlet branch. We provide suitable cleaning out
doors or cocks for the removal of the grease or sediment from the chamber and
we introduce an escape pipe or branch within the chamber which will enable
the grease to overflow when near the bottom end and which will at the same time
permit of the condensed water escaping when a certain predetermined level has
been reached within the chamber. We make our ribs or diaphragm baffle
plates or vanes in a straight, curved or spiral form as may be found most desirable
for the particular form of casing which is to be produced, and we employ a cover
with suitable connections at the upper end and may also arrange gauge glasses
or test cocks upon the casing for the purpose of indicating the level of the grease
or water within when so desired.
We make our casing of cast or wrought metal, the shape and method of connec-
tions being dependant upon the form of heater to which it is to be applied.
We employ an injector or exhauster using high pressure steam in connection
with the apparatus for the purpose of withdrawing air and for initially starting.
When employing the form of heater and condenser as described in the Specifica-
tion of our Application for Patent No. 21020 of 1897 herein before referred to,
we form a flange upon the outer portion of the body which encloses the coil

page_text: pipes to receive the jacket casting of our grease separator or chamber, the other
littings being arranged in the manner described in the said specification.
Dated this 26th day of May 1898.

Improvements in water Heaters, Condensers and Separators.
We, DAVID MEIN NESBIT, Engineer, and WALTER CLOWES, Working Engineer,
both of 12, Great James Street, Bedford Row, London, W.C., 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 has reference to improvements in connection with water heaters,
the object being to provide in one compact apparatus a separator for removing
the grease and impurities from steam which is to pass through the heating appara-
tus and coils, and a heater or condenser, through which the exhaust steam shall
pass.
In the two accompanying sheets of explanatory drawings:-
Figure 1 is a sectional elevation of one form of our improved heater and
separator.
Figure 2 is a sectional plan on the lines X X, and
Figure 3 is a sectional plan taken on the lines Y Y.
In carrying the invention into effect we arrange an outer grease chamber,
separator, jacket or casing A to enclose or surround an ordinary heater body B,
the interior portion of which heater body contains the series of bent or other
heating pipes arranged in any well known manner, although we find it particularly
advantageous to employ the arrangement of pipes and fittings as set forth in our
Application for Patent No. 21020 of 1897, and we are able to employ steam
pressure of a pressure less than that of one atmosphere.
The grease chamber or separator A which we employ to receive the exhaust
steam from the engine or other motor we arrange with a series of diaphragms
or ribs a about its, inner periphery and we form also when possible a number of
like ribs bor baffle plates upon the exterior periphery B of the heater casing, the
object being to ensure that the exhaust steam on its entrance at C into the
separator chamber shall be compelled to follow a tortuous path and thus to be
spread up and the grease to be deposited or caused to fall to the lower portion of
the chamber, while the outlet branch D we arrange on the opposite side of the
grease chamber preferably on a different level to that of the inlet branch. The
outlet D is connected to the inlet of the heater or condenser so that the steam
after passing through the separator will enter the heater or condenser free from
grease and like impurities. We provide suitable cleaning out doors E or cocks
for the removal of the grease or sediment from the grease chamber and we intro-
duce an escape pipe or collecting branch F within the chamber which will enable
the grease to overflow when near the bottom end and which will at the same time
permit of the condensed water escaping when a certain predetermined level has
been reached within the chamber. We make our ribs or diaphragm baffle plates
or vanes ab in a straight curved or spiral form as may be found most desirable
for the particular form of casing which is to be produced, and we employ a

page_text: cover G with suitable connections at the upper end and may also arrange gauge
glasses or test cocks upon the casing for the purpose of indicating the level of
the grease or water within when so desired. We make our casing of cast or
wrought metal, the shape and method of connections and fittings being dependent
upon the form of heater to which it is to be applied.
When employing the form of heater and condenser as described in the. Specifica-
tion of our Application for Patent No. 21020 of 1897 herein before referred to,
we form a flange H upon the outer portion of the body B, which encloses the
coil pipes, to receive the jacket casing A of our grease separator or chamber, and we
connect the outlet D of the separator with the inlet I of the heater or condenser
the other fittings being arranged in the manner described in the said specification.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In feed water heaters or condensers the combination of an outer casing with
the main casing or body of the heater or condenser for the purpose of forming
an impurity or grease separator space or chamber through which the steam passes
before entering the heating apparatus or coils; substantially as hereinbefore
described.
2. In feed water heaters or condensers the combination of a separator external
chamber formed about the heater or condenser casing or vessel with steam inlet
and outlet branches arranged at different levels of the outer separator chamber,
and with an overflow and grease collecting branch pipe provided within the
separator chamber substantially as hereinbefore described and as illustrated in
the accompanying drawings.
