Improvements in Means or Apparatus for Removing Impurities
from Water in Steam Boilers.
I RICHARD WITHINGTON BROMILEY SANDERSON of Office D Royal Exchange
Manchester in the County of Lancaster Cotton Merchant a communication to me from
abroad by John O'Brien and Samuel J. Weaver both of St. Louis Missouri, United
States of America Engineers, do hereby declare the nature of this Invention to be
as follows:-
:-
This invention relates to the Invention of "An improved feed water purifier
and heater for steam boilers" for which I obtained Letters Patent numbered 4342
and dated March 21, 1888.
The present improvements consist chiefly in combining with a feed water purifier
and heater of the construction specified in the said Letters Patent means or
apparatus for removing all or some of the impurities which pass through the
purifier and enter the boiler with the feed water.
In carrying out these improvements I employ a circulating pipe which enters
the end or side of the boiler at or about the water level and extends inward
terminating preferably below the aforesaid feed water purifier either at or about
the water level or the end of the pipe or a branch pipe therefrom may be carried
down to a point near the bottom of the boiler and preferably over a pipe connected
to a mud drum. Outside the boiler the circulating pipe is provided with valves or
taps and is by preference connected to the mud drum which is also provided with a
valve or tap and blow off cock.

Improvements in Means or Apparatus for Removing Impurities
from Water in Steam Boilers.
I, RICHARD WITHINGTON BROMILEY SANDERSON, of Office D, Royal Exchange,
Manchester in the County of Lancaster, Cotton Merchant, a communication to me from
abroad by John O'Brien and Samuel J. Weaver, both of St. Louis, Missouri, United
States of America, Engineers, 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 the invention of "An improved, feed water purifier
and heater for steam boilers" for which I obtained Letters Patent numbered 4342
and dated March 21, 1888.
or
The present improvements consist chiefly in combining with a feed water purifier
and heater of the construction specified in the said Letters Patent means
apparatus for removing all or some of the impurities which pass through the
purifier and enter the boiler with the feed water.
And in order that this invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings reference being
had to the figures, and letters marked thereon.
The Drawing represents in section the end of a boiler to which my improvements
are applied in which-
a is the shell of the boiler, b the flue and c a Galloway tube, d is the circulating
pipe which enters the boiler at or about the water level and is or may be provided

page_text: with a funnel shaped mouth d¹ which stands below the feed water purifier f, g is a
valve fitted on the pipe d which extends downward into the mud drum has shown
in full lines, the drum d is connected by a pipe i provided with a valvej to the
lower part of the boiler, preferably at a point opposite to the purifier f. A blow
off pipe on which is a valve k is fitted at or near the bottom of the mud drum.
The mode of operation is as follows:-
The feed water is admitted through a valve above the purifier f and so long as
the valves g and jare open and the valve k closed the water circulates in the direction
indicated by the arrows through the pipe d drum and pipe i from the upper to the
lower part of the boiler, and the impurities or a portion of the impurities contained
in the water will be deposited at the bottom of the drum h; these impurities may be
blown off at any time by closing either the valve g or j and opening the blow off
valve k.
As a modification of my invention I propose to dispense with the mud drum and
continue the pipe d downward as shown in dotted lines o and connect it to the pipe i
direct or to an enlarged pipe as shown in dotted lines m which communicates with the
boiler in the same manner as the pipe ; the pipe m serves the same purpose as the
mud drum and it is provided with a blow off valve n.
The Drawing shows my apparatus attached to the end of a boiler but I may attach
it to the side if more convenient to do so and I may fix more than one apparatus to
the same boiler.
By closing the valves g and j the cylindrical chamber may be removed and replaced
if necessary without interfering with the working of the boiler.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a steam boiler the combination with the feed water purifier ƒ of circulating
pipes and a mud drum the drum and the pipes being provided with valves substantially
as and for the purposes herein described.
2. The combination with the feed water purifier ƒ of circulating pipes d, and m,
provided with valves substantially as and for the purposes herein set forth.
3. The combination with a feed water purifier of circulating pipes, and valves, for
removing impurities from water in steam boilers substantially as and for the purpose
herein set forth.
4. The employment of pipes and chambers outside the boiler for the purpose of
collecting and removing impurities which may enter the boiler with the feed water
substantially as shown and described.
