IMPROVEMENTS IN AND MRAORDING LIONING
Year: 1870

page_text: LETTERS PATENT to Charles Alexander Calvert, of Manchester, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN
AND
MRAORDING LIONING "
PROVISIONAL SPECIFICATION left by the said Charles Alexander
Calvert at the Office of the Commissioners of Patents, with his
Petition, on the 22nd December 1870.
I, CHARLES ALEXANDER CALVERT, of Manchester, in the County of
Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR DRAWING OFF AND MEASURING LIQUIDS," to
be as follows:-
The object of this Invention is principally to measure and draw off a
certain definite quantity of the liquid at each movement of the handle
of a tap and to cause the number of movements to be counted and.
registered, so as to indicate on a dial the exact quantity of liquid
drawn off.
The apparatus consists principally of a vertical barrel or cylinder
working liquid-tight between two end plates; the said barrel being

page_text: provided with three or more tubes passing through from top to bottom,
the other or intermediate parts being solid. These tubes are each of
such a length and diameter as will exactly contain the quantity of
liquid intended to be drawn off at each movement of the handle. The
top plate is hollow forming a chamber, and communicates by a pipe
with the vessel containing the liquid and has an opening or openings
below corresponding in size and position with one or more of the said
tubes, so that as the barrel or cylinder is turned round these tubes are
brought seriatim beneath the openings and are thus filled with the
liquid. The bottom plate is also provided with a similar hole having
a short tube or spout attached, this hole being by preference towards the
front and not being opposite to any of the openings in the top chamber.
It will be evident that as the barrel is turned round the tubes will be
each filled in succession, and as they come opposite to the discharge
opening in the bottom plate they will discharge their contents. The
barrel is turned round by means of a lever handle provided with a
spring catch, which takes into holes or recesses in the outside of the
barrel corresponding in number and position with the tubes in the inside
thereof, each forward stroke of the handle turning the barrel a sufficient
portion of a revolution to discharge one tubeful of liquid, so that
supposing each tube to contain half a pint two strokes would give a
pint, four a quart, and so on. As the handle is moved backwards to
take a fresh hold the barrel remains stationary during the discharge of
one tube and filling of another.
When the liquid is required to be aërated I have an additional
opening through the top plate opposite to the discharge opening, and
I connect this with a small air pump or syringe worked by the move-
ment of the handle, so that as each tube is brought over the discharge
opening a portion of air is forced through it, which not only aërates
the liquid but facilitates its discharge from the tube.
The movement of the handle or of the barrel is to be connected to
an ordinary train of counting wheels in such a manner as to cause them
to indicate on a dial the number of movements of the handle, and hence
the number of (say) half-pints, quarts, or gallons drawn.
When this apparatus is employed for filling bottles to an exact
measure, the return stroke of the handle may be employed for forcing
in the cork.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Alexander Calvert in the Great Seal
Patent Office on the 22nd June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ALEXANDER CALVERT, of Manchester, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of December, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Alexander Calvert, Her special
license that I, the said Charles Alexander Calvert, my executors, admi-
nistrators, and assigns, or such others as I, the said Charles Alexander
Calvert, 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 APPARATUS FOR DRAWING OFF AND MEASURING LIQUIDS,"
upon the condition (amongst others) that I, the said Charles Alexander
Calvert, 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 Charles Alexander Calvert, 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) :—
The object of this Invention is principally to measure and draw off a
certain definite quantity of the liquid at each movement of the handle
of a tap, and to cause the number of movements to be counted and
3 registered, so as to indicate on a dial the exact quantity of liquid
drawn off.

page_text: The apparatus consists principally of a vertical barrel or cylinder
working liquid-tight between two end plates, the said barrel being pro-
vided with three or more tubes or chambers passing through from top
to bottom, the other or intermediate parts being solid. These tubes or
chambers are each of such a length and diameter as will exactly contain
the quantity of liquid intended to be drawn off at each movement of the
handle. The top plate communicates with the vessel containing the
liquid, and has an opening or openings corresponding in size and position
with one or more of the said tubes, so that as the barrel or cylinder is
turned round these tubes are brought seriatim beneath the opening, and
are thus filled with the liquid. The bottom plate is also provided with
a similar hole having a short tube or spout attached, this hole being by
preference towards the front and not being opposite to any of the openings
in the top chamber. It will be evident that as the barrel is turned round
the tubes will be each filled in succession, and as they come opposite to
the discharge opening in the bottom plate they will discharge their
contents. The barrel is turned round by means of a lever handle pro-
vided with a spring catch which takes into holes or recesses in the
outside of the barrel corresponding in number and position with the
tubes in the inside thereof, each forward stroke of the handle turning
the barrel a sufficient portion of a revolution to discharge one tubeful of
liquid, so that supposing each tube to contain half a pint two strokes
would give a pint, four a quart, and so on. As the handle is moved
backwards to take a fresh hold the barrel remains stationary during
tbe discharge of one tube and filling of another.
If preferred the barrel may be made with two tubes only, in which
case the lever is fixed to the barrel, which does not revolve but merely
oscillates to the right or the left, each stroke of the lever (whether to
the right or to the left) drawing off the contents of one tube. Over the
discharge opening there is an air tube to assist the tube in discharging
itself, and when the liquid is required to be aërated I connect this with
a small air pump or syringe worked by the movement of the handle, so
that as each tube is brought over the discharge opening a portion of air
is forced through it, which not only aërates the liquid but facilitates its
discharge from the tube. The movement of the handle or of the barrel
is to be connected to an ordinary train of counting wheels in such
a manner as to cause them to indicate on a dial the number of move-

page_text: ments of the handle, and hence the number of (say) half-pints, quarts,
or gallons drawn.
When this apparatus is employed for filling bottles to an exact measure
the return stroke of the handle may be employed for forcing in the
cork.
Such being the nature and object of my said Invention for Improve-
ments in Apparatus for Drawing off and Measuring Liquids," I will
now proceed to describe more in detail the manner in which the same
is to be or may be performed or carried into practical effect, and in order
that the same may be clearly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with
figures and letters of reference corresponding with those in the following
explanation thereof;-
In the annexed Drawing Fig. 1 is a vertical section of the improved
apparatus, and Fig. 2 an elevation of the same with part of the casing
removed; Fig. 3 is a plan view of the apparatus complete, and Fig. 4 a
similar view with the top of the casing removed; Fig. 5 is a horizontal
section through about the line A, B, in Fig, 1, and Fig. 6 is an underneath
view.
a, a, is the casing which communicates with the barrel or other vessel
by means of a pipe b, b; c, c, is the cylinder revolving between the top
plate d, d, and the bottom plate e, e. The cylinder is provided with
three tubes or chambers f, f, f, each of such a capacity as to contain the
smallest definite quantity desired to be measured. The top plate is
provided with a curved slot 9, 9, so as to admit the liquid in the casing a, a,
to the two back tubes whilst the front tube is being discharged and has
an opening j, j, above the front tube. The bottom plate is provided
with a hole and discharge tube h, h. i, i, is the lever handle, and k, k,
the spring catch which takes into the notches or recesses in the ratchet
or catch wheel 1, 1, fixed on the axis of the cylinder c, c. m, m, is an
ordinary counting apparatus, the first wheel of which is formed with an
eye fitting on the end of the axis of the said cylinder. Each motion to
and fro of the handle i, i, as indicated by the dotted lines in Figs. 5 and 6,
will turn the cylinder one-third of a revolution, and thus bring cach of
the tubes ff. f, successively over the discharge tube h, h, and at the
same time the other two tubes will be filled through the opening or
slot g, g, and each movement of the handle will be registered and indicated
by the apparatus m, m.

page_text: Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be performed
or carried into practical effect, I wish it to be understood that I claim as
my Invention the improvements in apparatus for drawing off and
measuring liquids as herein-before described and exhibited in the
annexed Drawings, or any mere modification or imitation thereof con-
structed and operating in substantially the same or a similar manner.
In witness whereof, I, the said Charles Alexander Calvert, have
hereunto set my hand and seal, this Twentieth day of June, in
the year of our Lord One thousand eight hundred and seventy-
one.
