page_text: executors, administrators, and assigns Her Royal Letters Patent for
the same, and have made solemn Declaration that I really believe
myself to be the first and true Inventor thereof.
NOW KNOW YE, that I, the said Prosper Huerne, do hereby declare
that the following Complete Specification, under my hand and scal, fully
describes the nature of my said Invention, and the manner in which
the same is to be performed.
My Invention relates to an improved water filter to be attached to
water faucets in buildings for the purpose of filtering the water which is
used for drinking and other purposes.
The Drawing hereunto annexed, and forming part of this my Completo
Specification, represents in sectional elevation a filter embodying my
Invention.
A is an elongated circular shell, through the upper end of which the
pipe 6 passes. Inside of this shell is an clongated porous stone or
ovoid G, which is shorter than the shell, and somewhat smaller in cross
section. This ovoid has a hole or passage B extending longitudinally
through its center, and is supported in place inside of the shell by the
end of the pipe b being secured in the upper end of the passage. A
short pipe n similar to bis received in the lower end of the passage, and
passes down through. the lower end of the shell, thus fixing the ovoid
inside of the shell with a spaco L, L, above, and a similar one below,
these spaces being connected by the narrow spaces between the shell
and the sides of the stone.
The pipe A² connects with the supply main, and communicates with
the interior space L, L, at the upper end of the shell, a cock S serving
to regulate the flow.
of the house,
The pipe 6 passes directly up to and through the roof
where it is connected by a side pipe with a jar or tank J. A short pipe
connects the two pipes A. and b, and a cock C¹ serves to cut off com-
munication between the two when desired.
K is a distributing pipe, which can be extended to any part of the house.
Thus the water, which is admitted into the chamber between the stone
and shell through the pipe A¹ by means of the cock S, will be forced
through the porous stone by the pressure of the water into the chamber B,
from whence it can be drawn for use through the pipe n. When the

and the jar J is high enough, C¹, S, and F are closed, and M. and V
opened until the water stops running through the waste pipe M; then
the cock is opened until the water runs clear through the waste
pipe M. When the water is extremely muddy a special tank may be
added to allow the mud to settle previous to introducing it into the filter.
When the water has a bad odor charcoal or other deodorizer may be
placed in
Having thus described my Invention, what I claim and desire to
secure by Letters Patent is,—
First. The reversible hollow globe or oblong shell A with its tubes V,
S, M, in combination with the corresponding filtering stone G, having
the hole or passage B and short pipes and tubes b, n, substantially as
and for the purpose above described.
Second. The hollow globe or shell A with its filtering stone G in 1
combination with the pipes A¹, b, and tank J, said pipes being connected
by the pipe C with its cock C', by which the operation of the filter may
be reversed for cleaning the filter with filtered water, substantially as
above described.
Third. A reversable globe or ovoid filter, provided with a
corrc. 2
sponding interior filtering stone, said globe or ovoid being reversable
for the purpose of cleaning the stone, substantially as above described.
In witness whereof, I, the said Prosper Huerne, have hereunto set
my hand and seal, this Seventeenth day of December, in
the year of our Lord One thousand eight hundred and seventy- 2
three.
