page_text: I, JOSEPH BOND Jr. of 611 North 8th St. Richmond, State of Virginia, U.S.A,
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 following statement :—
This invention relates to Boiler Cleaners, and has for its object to provide
means for removing the impurities from the water in steam boilers of all
descriptions and thereby present such impurities from being deposited upon the
inside of the boiler forming scale or incrustations.
The invention is based upon the fact that when heat is applied a current is
established in the water in the boiler causing the water to flow from near to front
at the bottom of, the boiler, thence upward to the surface and thence to the rear
of the boiler. This current is most apparent and direct in the upper part of the
boiler and the impurities of all kinds, whether of greater or less specific gravity
than the water, are carried by this surface current from the front towards the rear,
while the impurities are thus moving with the current they can readily be
gathered and removed from the boiler thereby purifying the water and preventing
the formation of scale or incrustation upon the interior surface of the boiler. The
application of this device will also automatically clean boilers that have become
foul, of all mud, scale, &c., the cause of scaling being removed, the old scale will
fall off.
To the accomplishment of the above ends this invention consists in means
whereby said impurities are separated from the water and discharged from the
boiler substantially as hereinafter set forth, and illustrated in the accompanying
drawings, wherein similar figures of reference denote similar parts.
In the drawings :-
Fig. 1 is a longitudinal sectional view of a steam boiler embodying my
invention.
Fig. 2 is a detail perspective view of the device which collects impurities within
the boiler.
Fig. 3 is a diagram view showing said device in position.
Fig. 4 is a detail view of the pipe which conveys water containing impurities
from the boiler, and

page_text: Figs. 5 to 7 mnclusive illustrate different constructions of the device for separating
impurities from the water.
In the present embodiment of this invention a boiler 1, is shown as in position
upon a furnace having a combustion chamber 2, located at one end the products of
combustion from which, are adapted to pass over a bridge wall 3, and thence
beneath the boiler to a smoke stack situate at the rear thereof in the ordinary
manner.
By this arrangement of parts it will be readily apparent that the forward
portion of the boiler, directly above the combustion chamber will be exposed to
a greater degree of heat than the opposite rear end thereof, and that consequently
water within said boiler by exposure to said different degrees of heat will be
caused to circulate back and forth in the direction of the arrows 4, that is to say
at the forward end of the boiler, upward currents will, by the excess of heat, be
formed which will, when reaching the surface of the water, move rearward and at
or near the rear end of the boiler descend to again pass forward as above described.
It will be apparent that impurities held in suspension in said water will by said
current be carried backward in the boiler at or near the surface of the water and
hence to separate said impurities from the water it is necessary that such impurities
be caught in transit which end is accomplished in and by the following described
manner, and means:-
A triangular plate 5, preferably formed in two sections, is adjustably or otherwise
secured within the boiler just below the upper surface of the water, and extends at
its forward edge nearly or quite from side to side of the boiler, see Fig. 3. This
plate is provided with upwardly turned side flanges 6, which converge toward and
are joined near the rear end of the boiler by a slightly rounded portion 7.
A pipe 8, is provided with an inverted funnel shaped lower end 9, which extends
from a point just within the junction of the sides 6 and above the surface of the
plate 5, outward through the boiler side and communicates with a chamber 10,
formed within a mud drum 11, arranged exteriorly of said boiler. A partition 12
which is arranged within the mud drum 11, between the opening of the pipe 8,
and the mouth of a pipe 13, extending from said mud drum to a point within the
boiler near the bottom thereof.
A blow off pipe 14, extends from a point near the bottom of the mud drum 11,
to conduct sediment therefrom. Cocks 15 and 16 are interposed in the pipes 13
and 14, respectively to open or close said pipes to or against the passage of fluid
therethrough.
The operation of this invention is as follows-The boiler having the proper or
desired quantity of water therein, and the plate 5 extending just below the surface
thereof, a fire is started within the combustion chamber, whereby currents are
formed in said water as hereinbefore set forth, which in passing rearward convey
to and deposit upon said plate 5, all foreign matter contained in said water, at the
same time the generation of steam in the boiler will operate to cause a current of
water through the pipe 8, to the mud drum 11, and thence through the pipe 13, to
the boiler. It will be remembered that the mouth or lower flaring end of the
pipe 8, is situated just above the surface of the plate 5, between the converging
rear ends of the walls 6 thereof, and hence it follows that as impurities have by
the currents in the water as before described been deposited upon said plate such
impurities will together with the water above the plate be drawn into said pipe 8,
and be discharged therefrom within the chamber 10, and against the partition 12
therein, and thereby be deflected towards the bottom of the chamber 10, where a
separation of the one from the other will be effected, the purified water passing
from the chamber through the pipe 13, to the boiler while the impurities remain
in said chamber and may be removed therefrom through the blow off pipe 14.
Fig. 5 shows the mud drum 11 provided with an inclined solid partition the
lower end of which is connected by a perforated partition 17, with the forward
end of the casing.

page_text: Fig. 6 shows the opposite ends of the mud drum separated by an inclined
perforated partition while Fig. 7 shows the interior of the drum divided into two
compartments by a horizontal perforated partition.
Great importance is attached to the employment of the partition 12, in con-
nection with the mud drum 11, as thereby a more thorough separation is effected
between water and the impurities contained therein, than could possibly be effected
in a mud drum not provided with said partition.
Great importance is also attached to the form of the plate 5, and its connected
side flanges 6, and to the inverted funnel shape of the lower end of the pipe 8, as
by the former impurities in the water are collected and condensed below said pipe,
while the shape of the latter prevents its becoming clogged by such impurities.
It will be understood that the mud drum may be placed in any desired location
with reference to the boiler, also that said mud drum together with the remaining
parts comprised in this invention, may be used in connection with any desired
form or style of boiler, portable or stationary.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. A triangular shaped plate having upwardly turned side flanges in combination
with a boiler, substantially as described.
2. A boiler cleaner, consisting of a triangular plate having side flanges adapted
to be placed below the surface of the water to collect impurities therefrom, and
means to convey said impurities from said boiler, as and for the purpose specified.
3. A boiler cleaner, consisting of a triangular plate provided with converging
side flanges placed below the surface of the water and a pipe having an inverted
funnel shaped end, extending from a point immediately above said plate into a
mud drum having a partition therein, substantially as described.
4. A boiler cleaner, consisting of a triangular plate having upwardly turned
converging side flanges and adapted to be placed immediately below the surface of
the water in the boiler, a pipe having an inverted funnel shaped lower end, a mud
drum having a partition, a return pipe connecting said mud drum with the boiler,
and a blow off pipe, substantially as described.
5. In a boiler cleaner, a mud drum enclosing a chamber 10, divided by a
partition into two compartments, and pipes 8 and 13 which connect the opposite
ends of said chamber with the interior of the boiler, substantially as described.
