Year: 1859

page_text: LETTERS PATENT to George Henry Baylis, of 18, Vauxhall Walk,
Lambeth, in the County of Surrey, and Francis Robinson, of 88,
Salisbury Street, Lisson Grove, in the County of Middlesex, for the
Invention of "AN IMPROVED INDICATOR FOR REGISTERING THE WITHDRAWAL
OF LIQUIDS FROM VESSELS."
Sealed the 2nd August 1859, and dated the 4th February 1859.
PROVISIONAL SPECIFICATION left by the said George Henry Baylis
and Francis Robinson at the Office of the Commissioners of Patents,
with their Petition, on the 4th February 1859.
We, GEORGE HENRY BAYLIS of 13, Vauxhall Walk, Lambeth, in the County
of Surrey, and FRANCIS ROBINSON, of 88, Salisbury Street, Lisson Grove, in
the County of Middlesex, do hereby declare the nature of the said Invention
for "AN IMPROVED INDICATOR FOR REGISTERING THE WITHDRAWAL OF LIQUIDS FROM
VESSELS," to be as follows: -
This Invention has for its objects the indication of the quantity of liquids
withdrawn from casks and other vessels, and as a protection for publicans
against the dishonesty of servants.
The indicator is composed of a circular box having a dial on its front
surface marked with gills, half pints, pints, quarts, &c., up to one gallon; on
the lower part of this dial a second smaller dial is placed, marked with gallons
only. A spindle is passed through the centre of the box, having a hand on its

page_text: outer end, the other end the other end passing through a barrel or cylinder,
over which is wound a cord, one end whereof is secured to the barrel, the other
end having a float attached thereto, which enters the top of the cask or other
vessel and floats upon the surface of the liquid, so that as the liquid falls in
the vessel the quantity withdrawn is indicated upon the dials until the vessel
becomes empty.
The two dials are worked together within the box by toothed wheels, as in
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Henry Baylis and Francis Robinson in the Great
Seal Patent Office on the 4th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
HENRY BAYLIS, of 18,,Vauxhall Walk, Lambeth, in the County of Surrey, and
FRANCIS ROBINSON, of 88, Salisbury Street, Lisson Grove, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Henry Baylis, and Francis Robinson, Her special licence
that we, the said George Henry Baylis and Francis Robinson, our executors,
administrators, and assigns, or such others as we, the said George Henry
Baylis and Francis Robinson, our 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 "AN IMPROVED INDICATOR FOR REGISTERING THE WITHDRAWAL OF LIQUIDS FROM
VESSELS," upon the condition (amongst others) that we, the said George
Henry Baylis and Francis Robinson, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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.

page_text: NOW KNOW YE, that J, the said George Henry Baylis, 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 :-
This Invention has for its objects the indication of the quantity of liquids
withdrawn from casks and other vessels, and as a protection publicans against
the dishonesty of servants.
The indicator is composed of a circular box having a dial on its front
surface marked with gills, half pints, pints, quarts, &c., up to gallons; on the
lower part of this dial a second smaller dial is placed, marked with gallons only;
a spindle is passed through the centre of the box, having a hand on its outer
end, the other end passing through a barrel or cylinder, over which is wound
a cord, one end whereof is secured to the barrel, the other end having a float
attached thereto, which enters the top of the cask or other vessel and floats
upon the surface of the liquid, so that as the liquid falls in the vessel the
quantity withdrawn is indicated upon the dial until the vessel becomes empty.
The two dials are worked together within the box by toothed wheels, as in
clockwork.
. In order to explain our said Invention as completely as possible, we now
proceed to describe the best means, we are acquainted with for carrying the
same into practical effect, and refer to the accompanying Sheet of illustrative
Drawings, and to the numeral figures and letters of reference marked thereon

page_text: the part of the tube c that is within the cask d is a float of
any
suitable
material attached to the end of the cord, so it appears evident that as the
liquid falls or is withdrawn from the cask, the float follows it and actuates the
barrel, Figure 3, which causes the index or hand 6 to move gently round
the dial, at the same time indicating the quantity of liquid withdrawn. For
instance, if intended for a spirit cask, the dial plate will be marked with
quarterns, half pints, pints, quarts, up to one gallon, when the index pointing
to the one gallon indicates the same on a smaller dial on the lower part of
that marked a. This may be done by attaching a pin on the front edge of
the barrel, which pin takes into a small toothed wheel affixed to the spindle
which carries the index or hand on the lower dial, consequently as the pin
moves the toothed wheel but one tooth at
time, the small dial indicates but
size of the wheel employed. If
one gallon for every tooth, according to the
the indicator is intended for beer, ale, or liquid contained in larger vessels,
then the larger dial may be indexed from one gallon up to one kilderkin,
while the smaller one indicates from one kilderkin to a barrel hogshead up
to a butt, by which time the butt will be emptied of its contents.
Another mode of indication is shown at Figure 2, where the dial plate will
be seen attached to the cask itself, instead of being detached as at Figure 1;
another mode is also shewn at Figure 4, where will be seen a straight tabular
index e, placed in front of the cask, and the float resting in a pipe within the
cask, the cord passing over a pulley f on the edge of the cask, to the end of
which is attached an indicating point or hand g, so that as the liquor falls the
indicator rises in a slide provided for the purpose.
In earthen vessels either of the before-mentioned indicators may be applied,
or a V-shaped piece may be cut out the whole depth of the vessel, and a piece
of glass, either plain or graduated, of the same shape be inserted, either with
cement, packing, or other convenient.
"
Having now fully described the nature and object of our said Invention
of "An Improved Indicator for Registering the Withdrawal of Liquids from
Vessels," together with the best means we are acquainted with for carrying
the same into practical effect, we would remark, in conclusion, that we do not
confine or restrict ourselves to the precise details herein described, and shewn
in the accompanying Sheet of Drawings, as many slight modifications may be
made therein without in any way departing from the principle of our
Invention, such as, for instance, the hands on the dial plate may be actuated
by other mechanical means than those which we have herein described, and
the cord, instead of passing up or along a pipe or a tube c, may be passed over
suitable pulleys or rollers placed in any convenient part of the building; but

page_text: what we claim as our Invention, intended to be secured to us by the herein
in part recited Letters Patent is, the use of a float in connection with an
index, for the purpose herein described and set forth.
In witness whereof, I, the said George Henry Baylis, have hereunto set
my hand and seal, this Fourth day of August, in the year of our
Lord One thousand eight hundred and fifty-nine.
