TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY BECK, of 139, Cannon Street, in the City of London, Consulting

WHEREAS I am in possession of an Invention for "A New on
IMPROVED APPARATUS FOR THE REMOVAL FROM HARD FEED WATER OF THOSE

page_text: MATTERS WHICH FORM DEPOSITS OR INCRUSTATIONS IN DOILERS OR OTHER ЦЕАТЕЛИ
VESSELS," and have petitioned Her Majesty to grant unto me, my
exccutors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that it has been communi-
cated to me from abroad by A. Bidtel, Manager of the Jute Manufactory,
Floridsdorf, near Vienna, in the Empire of Austria.
NOW KNOW YE, that I, tho said William Henry Beck, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement :-
The Invention has for object the separation from hard feed water,
previous to its introduction into the boiler or other heating vessel, of
those matters which if not previously removed would be deposited in
and form incrustations in such boilers or heating vessels.
The apparatus consists substantially of a mixer and a filter, or system of
filters of peculiar construction. The feed water is pumped through the
mixer along with such proportions of hydrates (as in the process known
as Clark's method) or solutions of soda and chloride of barium as will
saturate the carbonates and sulphates contained in the water so as
to convert them into a precipitate. This precipitate is then removed by
filtration of the liquid through the filter, and the feed water, which
is thus more or less completely freed from matters which would form
a deposit or incrustation, may then be forced into the boiler or other
heating vessel.
The apparatus is illustrated in the three Sheets of Drawings hereunto
annexed, of which Sheet 1 illustrates an arrangement with separato
mixer and filters adapted for the delivery of the filtered water to a
cistern below.
Sheet 2 illustrates an arrangement with separate mixer and filters,
adapted for forcing the filtered water into steam boilers or into an
elevated cistern.
Sheet 3 illustrates a combined mixer and filter arranged in a com-
pact form, both mixer and filter being comprehended in one vessel.
Similar letters of reference apply to like parts in all the Drawings.
Referring to Sheets 1 and 2 the water, hydrate, and soda, et cetera, are
pumped simultaneously by separate pumps and in proportions suited to
the depositablo matters contained in the water, into a preliminary

page_text: mixer h, from whence they flow together into the principal mixer, to
which it is connected by a branch pipe as shewn. This mixer is divided
into a series of annular chambers by partitions, the disposition of which
is such that the liquids are caused to pass over and under and up and
down between them, being by that means thoroughly mixed together;
the reaction of the chemical substances is also thereby effected in the
most complete manner. The liquids finally escape from the mixer by a
central pipe and are conveyed therefrom, by the connecting pipes shewn,
into a filter or filters, entering and rising to the top of such filter or
filters by annular openings ; they then pass down through the filter
cloths which rest upon the sieves a, b. (The filter cloths are stretched
over the sieves by the stretching rings k, l.) The liquids then pass
through the filtering material contained in the annular chambers of the
filter, rising and falling over and under the partitions, finally escaping
through the sieves c and by the cocks d, e, f, g, out of the filter.
In the case of Sheet 1, as before mentioned, the filtered water may be
run into a lower cistern, and in the case of Sheet 2 is forced into a
pressure tank, as shewn, and thence to the boiler or an elevated cistern.
The filters are by preference divided into four compartments, as
shown, and the cocks d, e, f, g, adapted to cach, serve to regulate the
filtering action of each compartment, and also as means for completely
washing out or cleansing the filtering material when necessary.
The above description of Sheets 1 and 2 will also render clear the
arrangement shewn in Sheet 3, which as above stated, represents a com-
bined mixer and filter, the only difference being that the liquids escape
from the mixer into the filter by a direct passage, as shewn, instead of
by a connecting pipe.
Having now described the nature of the said Invention, and the
manner in which the same is to or may be performed, I would have it
understood that I do not confine myself to the precise forms of the
apparatus or of the parts thereof shown and described, as they may be
varied without departing from the Invention, but what I do claim is,—
First. The general and special arrangement and construction of
the apparatus, substantially as described and illustrated and for the
purposes set forth.
Second. The apparatus for mixing the liquids together, whereby they
are forced first into a preliminary chamber ½ of the mixer, and after-

page_text: wards into the mixer itself, being caused to ascend and descend therein,
the whole arranged- and constructed substantially as described and
illustrated.
Third. The arrangement of an annular opening i for the entrance
into tho filter of the liquid to be filtered, substantially as described and 5
illustrated.
Fourth. The arrangement whereby the liquid to be filtered is forced
to travel up and down through the filtering material, substantially
as described and illustrated.
Fifth. The filter cloth and system of sieves a, b, and the peculiar 1
manner in which the filter cloth is kept stretched by means of stretching
rings k, l.
.
Sixth. The regulation of the filtering action of the four compartmented
filter by means of the regulating cocks d, e, f, g.
Seventh. The employment of the cocks d, e, f, g, for the purpose of 1
cleansing the filtering material.
In witness whereof, I, the said William Henry Beck, have
hereunto set my hand and seal, this Sixth day of August, in
the year of our Lord One thousand eight hundred and seventy-
four.
