do hereby declare the nature of the said Invention for "AN APPARATUS
FOR PURIFYING LIQUIDS IN A READY AND ECONOMICAL MANNER" to be as
follows, viz.
This Invention has reference to the construction of a compound cock
or tap, to one way of which is to be attached a filtering receptacle filled
with sponge, powdered charcoal, or other depurator, from which filtered
water may be drawn off. There being also another way from which
unfiltered water may be drawn off. So that purified or unpurified

filed by the said John Ryan in the Great Seal Patent Office, on
the 18th November 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN RYAN, of Liverpool Street, in the City of London, Surgeon, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of May, in the year
of our Lord One thousand eight hundred and fifty-three, in the
sixteenth year of Her reign, did, for Herself, Her heirs and succés-
sors, give and grant unto me, the said John Ryan, Her special licence
that I, the said John Ryan, my executors, administrators, and assigns,
or such others as I, the said John Ryan, my exccutors, administra-
tors, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-
pressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Chan-
nel Islands, and Isle of Man, an Invention for "AN APPARATUS FOR
PURIFYING LIQUIDS IN A READY AND ECONOMICAL MANNER," upon the
'condition (amongst others) that I, the said John Ryan, by an instru-
ment in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Scal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Ryan, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
The nature of my said Invention consists in or has reference to the
construction of a compound cock or tap, to a duct or way whereof is to
be attached a purifying or filtering chamber or receptacle filled with
sponge, powdered charcoal, or other purifying or filtering medium or
depurator, from which purified or filtered liquid can be drawn off'; and

page_text: water or liquid may thus be obtained from the same cock or tap as the
filtered or purified water or liquid.
DESCRIPTION OF THE DRAWINGS,
And in what manner the said Invention is to be performed or carried
out, as I consider most preferable..
Fig. 1, represents a cock or tap, such as just described, as constructed
with the views and intentions above set forth.
In this Fig. A, denotes the filtering chamber or receptacle filled with
sponge, powdered charcoal, or other filtering medium (or it may be
subdivided by perforated plates, so as to have one subdivision occupied
by sponge, another by powdered charcoal, and so on). It will be ob-
served that the duct or way B, leading from the reservoir of liquid
communicates at with the top of the said chamber or receptacle A,
and thus admits unpurified or unfiltered liquid thereto, which thus
enters the said chamber or receptacle, and becoming purified can be
drawn off by the cock or tap C, in the duct or way leading from the
filtering chamber, and also that unfiltered liquid proceeding from the
tank or reservoir containing the same may be drawn off' (the liquid
having first filled the filtering chamber) by the cock or tap D, in the
duct or way B, aforesaid.
In Fig. 2, is shewn an apparatus of the same character as the fore-
going, but specially adapted for a portable apparatus which may be
carried about and used as occasion may require.
In this Fig. F, denotes an inlet tube, fitted on the top of a filtering
chamber or receptacle G, which tube may be made detachable there-
from. H, denotes the exit tube, fitted with a stop cock. Upon the
inlet tube being connected with an ordinary funnel or vessel unfiltered
liquid may be poured in, which, passing through the filtering chamber
G, may be drawn off filtered by the exit tube H.
Fig. 3, represents a two way cock or tap K, denoting one duct or
way, and L, another duct or way, the same being adapted for filtering
or purifying liquids on a large scale; thus one of the ducts K, or L,

page_text: being connected and in communication with a filter placed eitlier inside
orfoutside the tank or reservoir, and the other of said ducts in coniu-
nication with the tank or treservoir, only the cock M, is so constructed
that being turned one way it will draw, off filtered or purified liquid
from the filter, and being turned the other way will draw off unfiltered
or unpurified liquid from the body of the tank or reservoir. If the filter
be placed inside the tank or reservoir, it will be necessary to provide an
air vent. In the above arrangements I do not consider it essential to
confine myself to any particular form or size of cock or tap, or filtering
chamber or receptacle.
Having now described the. nature of the said Invention, and in
what manner, the same is to be performed, I declare that what I claim
is, the Invention for An Apparatus for Purifying Liquids in a Ready
and Economical Manner," of the nature and character as herein set
forth and described. . :
