PROVISIONAL SPECIFICATION left by the said Richard Farrall Dale at.
the Office of the Commissioners of Patents, with his Petition, on the
30th November 1864.
I, RICHARD FARRALL DALE, of Shoe Lane, in the City of London,
Manufacturer, do hereby declare the nature of the said Invention for "A
NEW APPARATUS TO BE EMPLOYED IN DRAWING-OFF AND MEASURING PARAPPIN AND
OTHER OILS, APPLICABLE ALSO IN DRAWING BEER AND OTHER LIQUIDS, AND MEASURING
THE SAME," to be as follows:-
The main objects I have in view are to prevent the loss of volatile oils and
spirits by evaporation, and to prevent the objectionable smell arising from
drawing off paraffin and other like oils.
My apparatus consists of a vessel, by preference, entirely of glass, or it may
be of metal with a glass guage, with quantities such as half pint, pint, quart;
or any other marked off thereon, and formed with a collar at top to make
a tight connection with the outlet from an ordinary beer engine or other
like pump, while at bottom the vessel is fitted with a tap, and terminates in a
narrow outlet tube or nozzle. At top the vessel is fitted with an air or vent
pipe, which is by preference returned into the vessel from which the supply
is taken.

by the said Richard Farrall Dale in the Great Seal Patent Office on
the 30th May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
FARRELL DALE, of Shoe Lane, in the City of London, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of November, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Farrell Dale, Her special licence that I, the said Richard Farrell
Dale, my executors, administrators, and assigns, or such others as I, the said
Richard Farrell Dale, 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 "A NEW APPARATUS
TO BE EMPLOYED IN DRAWING-OFF AND MEASURING PARAFFIN AND OTHER OILS,
APPLICABLE ALSO IN DRAWING BEER AND OTHER LIQUIDS, AND MEASURING THE SAME,"
upon the condition (amongst others) that I, the said Richard Farrell Dale,
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 Richard Farrell Dale, do hereby declare
the nature of my 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, reference being had to the Drawings hereunto annexed,
that is to say :-
The main objects I have in view are to prevent the loss of volatile oils and
spirits by evaporation, and to prevent the objectionable smell arising from
drawing off paraffin and other like oils.
My apparatus consists of a vessel, by preference, entirely of glass, or it may
be of metal with a glass gauge with quantities such as half pint, pint, quart,
or any other marked off thereon, and formed at top with a collar to make a
tight connection with the outlet from an ordinary beer engine or other like

page_text: pump, while at bottom the vessel is fitted with a tap, and terminates in a
narrow outlet tube or nozzle. At top the vessel is fitted with an air or vent
pipe, which is by preference returned into the vessel from which the supply
is taken.
My Invention will be fully understood by reference to Figure 1 of the
accompanying Drawings.
a is a glass vessel supported on a stand b, and marked off with quantities,
as shewn; it is formed at top with a collar to make a tight connection with
the outlet c from an engine or pump d. The vessel a has fitted at bottom a
narrow outlet tube e, which passes through the stand b, and is provided with
a tap (not shown).
Figure 2 represents a modified arrangement in which the vessel a is sup-
ported by the tube c by which the liquid is supplied; f is the tap in the outlet
tube; g is an air or vent pipe to the vessel a, and h is a pipe leading
from the cask in which the liquid is contained to the engine d.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim con-
structing apparatus to be employed in drawing off and measuring paraffin and
other oils, beer, and other liquids, substantially as herein-before described and
illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Farrell Dale, have hereunto set
my hand and seal, this Thirtieth day of May, One thousand eight
hundred and sixty-five.
