Honiton, in the County of Devon, Civil Engineer, for the Invention
of "AN IMPROVED APPARATUS FOR SHOWING THE LEVEL OF LIQUID CON-
PROVISIONAL SPECIFICATION left by the said George Barons North-
cote at the Office of the Commissioners of Patents, with his Petition,
on the 5th June 1872.
I, GEORGE BARONS NORTHCOTE, junior, of Feniton, Honiton, in the
County of Devon, Civil Engineer, do hereby declare the nature of the
said Invention for "AN IMPROVED APPARATUS FOR SHOWING THE LEVEL OF
LIQUID CONTAINED IN A CASE OR VESSEL, AND FOR A PROPORTIONAL MEASURER,"
to be as follows:-
This Invention has for its object a ready way for showing the level
of the liquid contained in a cask or vessel, and for a proportional
measurer.

page_text: The apparatus for showing the level of the liquid in a cask or vessel
consists of a small portable tube which may be of some flexible
material with a glass or other transparent tube attached. The tube
is placed in communication with the liquid in the vessel by means
of the tap or by some other convenient method, for which purpose
one end of the tube is so made as to fit the tap readily. The liquid
will then rise in the tube to level in cask or vessel, and can then be
easily seen. Should the cask or vessel be air-tight, air must first be
admitted.
The proportional measurer shows the proportion a certain part bears
to the whole. It consists of several strips or rods fastened together
in such a manner, that they form moveable parallelograms allowing
of the apparatus being lengthened or shortened in the same plan as
lazy tongs, and at the same time showing certains portions, such as half
or quarter of the whole length.
To use the apparatus its length must be arranged the same as the
thing to which it is applied, when it will show where the half or any
other portion comes. It can be made to show the proportion any part
of any regular figure bears to the whole.
If applied to a vessel of regular form at the same time as the con-
trivance for showing the level of the liquid, it will show what proportion
the liquid bears to the vessel.
The arrangement is shewn in the annexed Drawings forming part of
SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said George Barons Northcote in the Great Seal Patent
Office on the 4th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BARONS NORTHCOTE, junior, of Feniton, Honiton, in the County of
Devon, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 3
Letters Patent, bearing date the Fifth day of June, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-fifth
year of Her reign, did, for Herself, Her heirs and successors,

manner of performing the same, I would have it understood that I
claim the improved apparatus, substantially as described, for shewing
the level of liquid contained in a cask or vessel, such apparatus being
capable of being attached to the cask or vessel by means of the ordinary
tap. I also claim the proportional measurer, substantially as described.
In witness whereof, I, the said George Barons Northcote, junior,
have hereunto set my hand and seal, this Twelveth day of
November, in the year of our Lord One thousand eight hundred
and seventy-two.

measure d and the figures on the measurer opposite to which the
liquid in the tube stands shew what proportion of the total
contents of the cask remain in it. The figures on the right
hand side of the measurer are for a cask on end & those
on the left hand for a cask on its side.
