page_text: LETTERS PATENT to Henry- Sugden-Evans, -of-the-Firm-of Evans,
Lescher, and Evans, of Bartholomew Close, in the City of London,
for the Invention of "IMPROVEMENTS IN TAPS, VALVES, OR APPARATUS FOR
MEASURING AND REGISTERING THE QUANTITY OF LIQUID PASSED THERE-
THROUGH."
Sealed the 9th October 1868, and dated the 16th April 1868.
PROVISIONAL SPECIFICATION left by the said Henry Sugden Evans at
the Office of the Commissioners of Patents, with his Petition, on
the 16th April 1868.
I, HENRY SUGDEN EVANS, of the Firm of Evans, Lescher, and Evans,
of Bartholomew Close, in the City of London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN TAPS, VALVES, OB
APPARATUS FOR MEASURING AND REGISTERING THE QUANTITY OF LIQUID PASSED
THERETHROUGH," to be as follows:-
The Invention has for its object improvements in taps, valves, or
apparatus for measuring and registering the quantity of liquid passed
therethrough, and relates to the application of a novel arrangement and
combination of parts whereby given quantities of liquid can be drawn off
from a cask or other vessel and the number of such quantities registered.

page_text: For this purpose I employ a two-way tap, cock, or valve, the two ways
opening alternately at right angles to each other, and thereby effecting
at one time a communication between the cask or vessel and a measuring
chamber, and at another time shutting off the communication from the
çask or other vessel and allowing the liquid in the measuring chamber to
run off into any desired receiver. The measuring chamber has working
therein a plunger which is connected by a link to a lever handle or other
means fixed on the axis of the two-way cock, and is operated in such
manner that directly. the communication between the cask or other
vessel and the measuring chamber is opened the plunger begins to
ascend and allows the measuring chamber to become filled, then directly
the position of the two-way cock is reversed for emptying the measuring
chamber the plunger begins to descend, and thereby forces out the liquid
contained therein. By employing suitable dials and a train of gearing
set in motion by any suitable part of the apparatus the number of times
the measuring chamber has been filled and emptied can be readily
ascertained,
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said Henry Sugden Evans in the Great Seal
Patent Office on the 16th October 1868,
TO ALL TO WHOM THESE PRESENTS SHALL COME, HENRY
SUGDEN EVANS, of the Firm of Evans, Lescher, and Evans, of
Bartholomew Closc, in the City of London, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of April, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Henry Sugden Evans, Her special licence
that I, the said Henry Sugden Evans, my executors, administrators, and
assigns, or such others as I, the said Henry Sugden Evans, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN

page_text: TAPS, VALVES, OR APPARATUS FOR MEASURING AND REGISTERING THE QUANTITY OF
LIQUID PASSED THERETHROUGH," upon the condition (amongst others) that
I, the said Henry Sugden Evans, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands
and seals, 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 Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Henry Sugden Evans, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof; that is to say :-
The Invention has for its object improvements in taps, valves, or
apparatus for measuring and registering the quantity of liquid passed
therethrough,-and-relates-to-the-application-of-a-novel-arrangement_and_
combination of parts whereby given quantities of liquid can be drawn off
from a cask or other vessel, and the number of such quantities registered.
For this purpose I employ a two-way tap, cock, or valve, the two ways
opening alternately at right angles to each other, and thereby effecting
at one time a communication between the cask or vessel and a mea.
suring chamber, and at another time shutting off the communication
from the cask or other vessel, and allowing the liquid in the measuring
chamber to run off into any desired receiver. The measuring chamber
has working therein a plunger, which is connected by a link to a lever
handle, or other means fixed on the axis of the two-way cock, and is
operated in such manner that directly the communication between the
cask or other vessel and the measuring chamber is opened the plunger
beings to ascend and allows the. measuring chamber to become filled,
then directly the position of the two-way cock is reversed for emptying
the measuring chamber the plunger begins to descend, and thereby
forces out the liquid contained therein. By employing suitable dials and
a train of gearing set in motion by any suitable part of the apparatus
the number of times the measuring chamber has been filled and emptied
can be readily ascertained.
And in order that my Invention may be more fully understood and
readily carried into effect I will proceed, aided by the accompanying
Drawings, more fully to describe the same.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, Figure 2 is a front view, and Figure 3 is a
sectional side view of a tap, valve, or apparatus for measuring the
quantity of liquid passed therethrough.
a, a, is the body of the cock or valve in which a chamber or receiver b
is formed. Within the lower part of the body a is fitted a conical plug c,.
which with the passages a¹, a³, and a forms a two-way cock. Within
the cylinder or chamber 6 works a piston or plunger d, a stuffing box b₁
being employed to prevent any escape of the liquid at that part. Upon
one end of the plug c is fixed the lever handle e, which is provided with
a slot e¹, in which the pin f¹ in the lower end of the link f works; the
pin f in the upper end of the link f is fixed to the cross head d',
which is connected to the piston or plunger d, and is guided at its ends
in slots formed in the uprights g. And in order to afford facility for
adjustment to varying quantities of liquid desired to be measured a
screw his employed, which is capable of being fixed at any desired.
height by the screw nuts h³, h¹, being tightened upon the cross bar g',
as will be well understood, thereby regulating the height to which
the plunger or piston d is raised, and consequently the capacity of
the chamber or receiver b.
The following is the mode in which the cock, valve, or apparatus is
used: -When the parts are in the position shewn in the Drawings by
the black lines the communication between the cask or other vessel
and the chamber 6 is opened, whereby the chamber 6 becomes filled
with liquid; the lever handle e is then depressed until it assumes the
position shewn by the red lines in the Drawings, and in doing so it first
turns the plug c into a position to cut off the connection between the
cask or other vessel and the passages a¹ and a leading to the chamber
or receiver b, and momentarily isolates the contents of the chamber or
receiver 6 from communication with either of the passages a¹ or a³; it
then immediately opens the communication between the chamber or
receiver b and the passage a³, and in doing so depresses the piston or
plunger d within the chamber or receiver b until it has forced out the
contents of such chamber or receiver 6 through the passage a³, when
the handle is again ready to be raised to the position shewn by the
black lines in order to measure another quantity of the liquid flowing
from the cask or other vessel through the apparatus. For registering

page_text: the quantities of liquid passing through the apparatus a click or driver,
which is connected to any suitable moving part of the apparatus, gives
motion to a ratchet wheel, and by a suitable train of wheels indicates
upon a suitable dial the number of times the receiver 6 has been filled
and emptied. I have not thought it necessary to shew on the Drawings
the mode of registering the quantities of liquid passed through the cock,
valve, or apparatus, as aided by the description above given such will be
readily understood.
Having thus described the nature of my said Invention, and the mode
in which I carry the same into effect, I would have it understood that I
do not confine myself to the precise details herein shewn and described;
but what I do claim is, the peculiar arrangement and combination of
parts of taps, valves, or apparatus for measuring and registering the
quantity of liquid passed therethrough, substantially as herein shewn
