PROVISIONAL SPECIFICATION left by the said Edward Kenworthy
Dutton, at the Office of the Commissioners of Patents, with his Petition,
on the 22nd June 1865..
I, EDWARD KENWORTHY DUTTON, of Sale, in the County of Chester, Mer-
chant, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN APPARATUS FOR MEASURING AND INDICATING THE FLOW OF
LIQUIDS," to be as follows:-
My Invention is designed for the purpose of measuring and indicating the
amount of liquid passing from one vessel to another; and the improvements
consist in the novel combination, construction, and arrangement of mechanism,.
which may be used as a tap for the purpose of measuring the flow. The plug of
this tap has a passage or thoroughfare so constructed within it that when one
half or other portion of a turn is given to the plug by means of a handle to which
it is attached, the liquor shall flow from the cask or reservoir to which such
tap is connected through the thoroughfare into a receiver of a certain given.
capacity; the air, contained in such receiver, when filling with liquid, being
expelled up a tube into a hollow air chamber of larger dimensions than: the

page_text: liquor receiver. When the receiver is full the liquid is forced up the air tube
and continues falling into the air chamber until an equilibrium or balance of
pressure is obtained between the two, at which time the handle actuating the
plug receives another half turn, which closes the inlet thoroughfare, and allows
the measured quantity of liquid to escape from the receiver through the tap
or valve, which having been reversed forms the outlet passage. The liquor
in the air chamber is held in suspension during the time the receiver is dis-
charging itself, but when refilling it is conducted by a tube into the inlet
thoroughfare, which thus allows a constant equilibrium to be maintained
between the air and liquor; each revolution of the plug causes the receiver to
be once filled and discharged, or the plug may be arranged to reciprocate as
in ordinary taps, having the same effect or reciprocations, the number of such
revolutions being ascertained by an ordinary indicating apparatus attached to
a shaft or rod extending from the plug or connected therewith.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Kenworthy Dutton, in the Great Seal Patent
Office on the 22nd December 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
KENWORTHY DUTTON, of Sale, in the County of Chester, Merchant, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of June, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Kenworthy Dutton, Her special license that I, the said Edward
Kenworthy Dutton, my executors, administrators, and assigns, or such others
as I, the said Edward Kenworthy Dutton, 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 Inven-
tion for "CERTAIN IMPROVEMENTS IN APPARATUS FOR MEASURING AND INDICATING
THE FLOW OF LIQUIDS," upon the condition (amongst others) that I, the said
Edward Kenworthy Dutton, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in

page_text: 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Kenworthy Dutton, 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, and accompanying Drawings (that is to say) :-
My Invention is designed for the purpose of measuring and indicating the
amount of liquid passing from one vessel to another, and the improvements
consist in a novel combination, construction, and arrangement of mechanism,
which may be used as a tap for the purpose of measuring the flow of liquids.
The plug of this tap has a passage or thoroughfare so constructed within it
that when one half or other portion of a turn is given to the plug by means of
a handle to which it is attached, the liquid shall flow from the cask or reser-
voir to which such tap is connected through the thoroughfare into a receiver
of a certain given capacity, the air contained in such receiver when filling
with liquid being expelled up a tube into a hollow air chamber usually of
larger dimensions than the liquid receiver. When the receiver is full the
liquid is forced up the air tube or through a tube hereafter mentioned, and
continues rising in the air chamber until an equilibrium or balance of pres-
sure is obtained between the air and liquid, at which time the handle actuating
the plug receives another half turn, which closes the inlet thoroughfare, and
allows the measured quantity of liquid to escape from the receiver through
the tap or valve which, having been reversed, forms the outlet passage. Tho
liquid in the chamber is held in suspension during the time the receiver is
discharging itself, but when refilling it is conducted by a tube into the inlet
thoroughfare, which thus allows a constant equilibrium to be maintained
between the air and liquid, each revolution of the plug causes the receiver
to be once filled and discharged, or the plug may be arranged to reciprocate
as in ordinary taps, having the same effect, the number of such revolutions or
reciprocations being ascertained by an ordinary indicating apparatus attached
to a shaft or rod extending from the plug or connected therewith. In order
that the Invention may be better understood and explained in detail I have
hereunto attached a Sheet of Drawings made about the full size, similar letters-
of reference being marked upon corresponding parts of the apparatus.
Fig. 1 represents a vertical section of the improved tap and apparatus in
connection for measuring and indicating the flow of the liquids, and Fig. 2
represents a front elevation of the same. In Figs. 1 and 2 a, a, is the frame-
work to which the apparatus is attached; b is the tap, and c the plug in which

page_text: the passage or thoroughfare d is constructed; the body of the tap 6 is supplied
with the two thoroughfares or passages e and f, each of which alternately can
be connected with the chamber or receptacle g, by turning the plug.c, the top of
which chamber fits into a groove formed in the under side of the collar h; a
similar groove formed in the upper surface receiving the circular mouthpiece of
a second chamber or receptacle i, which is usually of larger dimensions and
greater capacity than the chamber g. The aforesaid collar h forms a division
between the two chambers, and is furnished with two tubes or pipes and m,
which form passages, the former for air and the latter for liquid; n is the
ratchet wheel secured on the end of a spindle, projecting from the plug c, the
pin o secured to this wheel forces or carries round the projecting finger p,
secured to the shaft of the pinion q. When the plug of the tap is turned this
pinion transmits motion through the train of wheels r to the indicators on the
dials 8, and so indicates or registers the amount of liquid or the number of
portions of liquid passed through the tap. The action of the apparatus will
be readily understood by the following description:-The cask, barrel, or other
reservoir of liquid being placed at the required height above the tap, and being
connected therewith in the usual manner, the plug c, when in the position shewn,
allows the liquid to flow from the cask through the thoroughfare e, d, e, in its
course to the receiver or chamber g; this chamber is constructed to contain a
given quantity of liquid from which, during the time of filling, the air is dis-
charged through the tube into the air chamber or receptacle i, the capacities
of the measure 9 and air chamber i being so proportioned in relation to the
pressure of liquid that the liquid shall continue to flow after the measure is full,
the surplus rising through the tube m into the chamber i until an equilibrium
is effected between the pressure of air and liquid. The use of the tube m is
to maintain this equilibrium by connecting the air chamber with the measure
and the reservoir of liquid at such times as the plug is in position for filling
the measure, a hole u being made in the plug for that purpose. When the
receptacle g is filled, and it is required to discharge its contents, the plug b is
to be turned half or other suitable portion of a turn so as to reverse the
thoroughfare, so that the passage or thoroughfare e, d, e, through, which the
liquid enters the receptacle g is closed, and the thoroughfare or passage f, d, f,
is opened, through which the liquid contained in, the chamber g is discharged
through the tap into the vessels placed to receive it, the air returning to the
measuring chamber through the pipe 1, and assisting by its pressure to dis-
charge the liquid. The plug b at this time has received one complete turn,
which through its connection, as described, with the train of wheels r, has
communicated the same to the indicators; the ratchet n is allowed to turn

page_text: only in one direction, a catch being provided to check any back ward action in
order to prevent any attempt to reverse the indicators. I would remark that
the chamber may be made transparent and graduated, so as to enable the
attendant to draw off any portion of its contents by regulating the turning of
the tap in accordance therewith.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel employment, use, and application to measuring taps or valves
of a receptacle or receptacles, for the reception of the air expelled from the
measure during the process of filling with liquid, and for the supply of air to
the measure to assist in the discharge of the liquid from the measure.
Secondly, I claim the novel use and application of tubes or passages to
connect the air receptacle with the measuring chamber for the flow of liquid,
and for the passage of air between the air between the air receptacle and
the measuring chamber.
And, lastly, I claim the use of a tap for the measuring of liquid in which
the plug moves in one and the same circular direction, only as herein-before
described, set forth, and fully illustrated in the Drawings attached.
In witness whereof, I, the said Edward Kenworthy Dutton have here-
unto set my hand and seal, this Twentieth day of December, in the year
of our Lord One thousand eight hundred and sixty-five.
