IMPROVED APPARATUS FOR REMOVING GREASE, AIR, AND OTHER IMPURITIES FROM
FEED WATER. [Communicated to him from abroad by Dyson Dearbon Wass,
Sinclair Stuart, John Carlos Henderson and Thornton Motley, all of the City
County and State of New York, United States of America
The object of this Invention is to provide apparatus for removing from the feed
water of boilers etc. the grease, air, mud, and other impurities which are usually
carried by the feed water.
The Invention consists in a box or vessel provided with a series of transverse
partitions which alternately extend upward from the bottom and downward from
the top or cover whereby the vessel is divided into a series of compartments. A
longitudinal channel is formed in the bottom of the vessel or box extending from
end to end of the same and in communication with two way cocks on the ends of
the vessel which cocks are also in communication with the interior of the vessel
and with the inlet and outlet pipes respectively. When the valves-of the cocks
are raised against the upper seatings, the feed water passes directly through the
channel and not through the vessel and is not purified or cleaned but when the

page_text: valves are on the lower seatings, the feed water circulates through the vessel. By
this means if any parts of the vessel are broken or otherwise become inoperative
the feed water can be conducted directly through the channel thus avoiding the
passage through the vessel. The partitions form a series of compartments in the
vessel and each compartment is provided at the bottom of one side with a straight
cock for blowing off the mud and sediment that collects in the bottom of the
compartments.
The grease which floats on the surface of the water is removed by a flat funnel
shaped receptacle closed at the top bottom and sides and open only at the curved
edge. This receptacle is secured in a horizontal position to the inner surface of
one side of the box so that it projects thereinto. At its inner end the receptacle
is provided with a downwardly projecting channel which leads to a cock projecting
from the box.
The Invention further consists in an air cock connected with a float in the
vessel, whereby when the compressed air in the vessel depresses the level of the
water to a certain extent, the float opens the cock and permits the compressed air
to escape so that the level of the water can rise.
The cock is screwed into one side of the vessel in such a manner that it projects
from the inner surface and it is provided with an arm which strikes against the
wall of the vessel and prevents the float from descending too far.
By means of this apparatus the grease contained in the feed water passing
through the box collects on the surface of the water, and passes into the funnel
shaped receptacle and away through the channel. The air contained in the water
collects in the top part of the vessel, and as the air gradually accumulates, the
pressure increases, and presses the level of the water downward. The float descends
with the level of the water and opens the cock thereby permitting the compressed
air to escape. The level of the water then rises immediately and the cock is
closed

ALEXANDER MELVILLE CLARK of the Firm of A, M, and W, Clark of 53 Chancery

IMPROVED APPARATUS FOR REMOVING GREASE, AIR, AND OTHER IMPURITIES FROM
FEED WATER" A communication to me from abroad by Dyson Dearbon Wass,
Sinclair Stuart, John Carlos Henderson, and Thornton Motley, all of the City,
County, and State of New York, United States of America.
The object of this Invention is to provide apparatus for removing from the feed
water of boilers, &c, the grease, air, mud, and other impurities which are usually
carried by the feed water.
The Invention consists in a box or vessel provided with a series of transverse
partitions alternately extending from the top and bottom, whereby the vessel is
divided into a series of compartments. The grease remains on the surface of the
water and is caught by a flat funnel and conducted out of the vessel. The
Invention further consists in an air cock connected with a float in the vessel
whereby when the compressed air in the vessel depresses the level of the water to
a certain extent, the float opens the cock and permits the compressed air to escape
so that the level of the water can rise. The Invention further consists in a
channel extending longitudinally across the bottom of the vessel and in devices for
placing the inlet and outlet pipes in communication with the vessel or with the
said channel. The Invention also consists in mud cocks projecting from the sides
of the compartments at the bottoms of the same.
The Invention is illustrated in the accompanying drawings in which similar
letters of reference indicate corresponding parts in all the figures. Figure 1 is a
plan view of the improved apparatus for removing grease, air, and other impurities
from feed water, half of the cover being removed. Figure 2 is a longitudinal
elevation of the same, parts being broken out and others shown in section.
Figure 3 is a cross sectional elevation of the same. Figure 4 is a side view of the
air cock and its float.
A trough shaped vessel A having a cover B bolted on the same, is provided
with a series of transverse partitions C which alternately extend upward from the
bottom of the vessel and downward from its cover. A longitudinal channel R is
formed in the bottom of the vessel or box A which extends from end to end of the
same and is in communication with two way cocks S provided on the ends of the.
vessel, which cocks S are also in communication with the interior of the vessel A
and with the inlet and outlet pipes D and E respectively. If the valves T of the
cocks S are raised against the upper seatings, the feed water passes directly through
the channel R and not through the vessel A and is not purified or cleaned, but
when the valves T are on the lower seatings, the feed water circulates through
the vessel or box A. By this means if any parts of the vessel A are broken or
otherwise become inoperative, the feed water can be conducted directly through
the channel R, thus avoiding the passage through the vessel A. The parti-
tions C form a series of compartments in the vessel A. and each compartment is
provided at the bottom of one side with a straight cock u for blowing off the mud
and sediment that collects in the bottom of each compartment.
F is a flat funnel shaped receptacle closed at the top, bottom and sides and only
open at the curved edge. This receptacle is secured in a horizontal position to the
inner surface of one side of the vessel A so as to project thereinto. At its inner

page_text: end the receptacle F is provided with a downwardly projecting channel G which
leads to a cock projecting from the vessel A at I. His a cock screwed into one
side of the vessel A in such a manner that it projects from the inner surface
thereof, which cock is combined with a float J and is provided with an arm K
which strikes against the wall of the vessel A and prevents the float J from
descending too far.
The operation is as follows:-The grease contained in the feed water passing
through the vessel A collects on the surface of the water and passes into the flat
funnel shaped receptacle F and away through the channel G. The air contained
in the water collects in the top part of the vessel, and as the air gradually
accumulates, the pressure increases and presses the level of the water downward.
The float J descends with the level of the water and opens the cock H, thereby
permitting the compressed' air to escape.
The level of the water then rises
immediately and thereby the cock H is closed.
Having described the nature of the said Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
hereinbefore in part recited Letters Patent is.
1st. The combination with the vessel A provided with transverse partitions C, of
a device for collecting the grease, and of an automatically operating outlet for the
air that collects in the vessel, substantially as herein shown and described, and for
