Improvements in Feed Water Purifiers.
I, NORMAN LITTLE HAYDEN, of Hotel Empire, New York, in the County of
New York and State of New York, United States of America, Gentleman, 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 follow-
ing statement:
My invention relates to certain improvements in feed water purifiers, the
object being to more effectually trap the dirt and sediment as well as the particles
held in suspension in the water and prevent them from passing to the boiler.
The invention is illustrated by means of a side elevation of an apparatus shown
in the drawings, the purifier proper being shown in diametrical vertical section
to reveal the interior construction thereof.
Referring to these drawings, A, represents a hot well from which leads a water
pipe, B, discharging into an injector C, supplied with steam by means of a
steam pipe D. The injector forces the water, heated by the steam, through the
pipe E, into the purifier proper F. This purifier consists of an enclosed vessel
having a lower settling chamber f and intermediate filtering chamber f¹ filled
with suitable filtering material and an upper pure water chamber f2, from which
a pipe G leads to the boiler. The filtering material is confined between two
perforated partitions, f³, f*, and a little below the latter is a diaphragm, f³,
preferably inclined downward toward its central portion and there provided with
a downwardly extending tubular portion, f. The inlet pipe, E, has a nozzle, e,
discharging the heated water into the purifier beneath the diaphragm, f, and
above the level of the bottom of the tubular portion thereof, f. The heating
of the water aids the deposit of the sediment contained therein and time for such
deposit is insured by the diaphragm, f5, and the pipe, f6, which prevents the
water from passing directly upward. A perforated coil, H, is laid just below
the diaphragm, fo, and leads into a discharge pipe, h, through which the floating
impurities may be drawn off. A discharge pipe, I, leading from the bottom
of the purifier, provides means for drawing off the sediment. From the pipe, E,
a branch, J, leads upward over the purifier and connects with the pipe, G, to
enable the purifier to be cut out of the system for cleaning or for other purposes.
A branch pipe, K, leads from the pipe, J, into the pure water chamber of the
purifier which is intended for use in washing out the filtering material.
branch pipe, L, leads from the steam pipe directly into the pure water chamber
of the purifier and is intended for use in blowing out the impurities from the
purifier.
A
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1: In a feed water purifier, a casing having a closed chamber, a central pipe
extending downmand th

page_text: bottom of the chamber, a discharge pipe, for light impurities, leading from the
upper part of the chamber, and an inlet pipe below the top of the casing and
above the bottom of the outlet pipe, the distance of the inlet pipe below the
top of the casing being sufficient to avoid forcing the floating impurities down-
ward and to permit said impurities to gather in the top of the casing, and the
extension of the outlet pipe below the inlet pipe being sufficient to compel the
sediment in the water to travel in a downward direction before it can enter the
outlet pipe, substantially as set forth.
2: In a feed water purifier, the combination with a casing having a closed
chamber, of an outlet pipe extending centrally downward into said chamber,
discharge pipes for impurities, leading, respectively, from the top and bottom of
the chamber, and an inlet pipe below the top of the chamber and above the
lower end of the outlet pipe; said inlet pipe being inclined, to give a cyclonic
action on the water in the chamber, and its distance below the top of the chamber
being sufficient to avoid forcing the floating impurities downward and to permit
said impurities to gather in the top of the chamber, and the extension of the
outlet pipe below the inlet pipe being sufficient to compel the sediment in the
water to travel downward before it could enter the outlet pipe, substantially as
set forth.
