Year: 1872

page_text: LETTERS PATENT to James Millar Ure, of Glasgow, in the County
of Lanark, North Britain, Engineer, for the Invention of "“Im-
PROVEMENTS IN MEASURING TAPS OR APPARATUS FOR DRAWING OFF AND
MEASURING LIQUIDS."
Sealed the 16th May 1878, and dated the 21st November 1872.
PROVISIONAL SPECIFICATION left by the said James Millar Ure at
the Office of the Commissioners of Patents, with his Petition, on the
21st November 1872.
I, JAMES MILLAR URE, of Glasgow, in the County of Lanark, North
3 Britain, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MEASURING TAPS OR APPARATUS FOR DRAWING OFF AND
MEASURING LIQUIDS," to be as follows, that is to say :—
This Invention relates to a simple and efficient form of tap or apparatus

page_text: -
The apparatus is formed with a slightly coned or tapered hollow body,
to be inserted into the cask or other vessel from which the liquid is to
be withdrawn, the smaller end being, by preference, inside the cask or
vessel. A hollow tapered plug is fitted to work liquid-tight in the body
like the plug of an ordinary tap, but with the end on which the handle
is fixed projecting out at the front end of the body, whilst the other
smaller end is inside of the cask or vessel, and is held by a screw and
nut in the ordinary way. In the part of the body which is inside the
cask or vessel, there are two slots one along the top and the other
along the bottom, and in the external part there is an air hole at the
top and a discharge spout at the bottom. The hollow plug is formed
with two diametrically opposite longitudinal slots at its inner part, and
with two openings at right angles to these slots, but at its front end.
When the tap is shut the slots in the body and plug coincide, and the
plug becomes filled, the air in it escaping through the upper slots into
the vessel and dispensing with a vent peg. On the plug being turned a
quarter round the slots inside become closed from being at right angles
to each other, and the openings at the front end then coincide with the
discharge spout and air hole respectively, and allow the plug to empty.
The quantity of liquid discharged at each action will be equal to the
internal capacity of the hollow plug, and the body and plug can be
made of different sizes to give different measures.
The annaratus may be modified by making the plue with two on

page_text: of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Millar Ure, Her special licence
that I, the said James Millar Ure, my executors, administrators, and
assigns, or such others as I, the said James Millor Ure, 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
MEASURING TAPS OR APPARATUS FOR DRAWING OFF AND MEASURING LIQUIDS,”
upon the condition (amongst others) that I, the said James Millar
Ure, 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 James Millar Ure, 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 in writing, reference being had to the accom-
panying Drawings, that is to say :-
My said Invention relates to a simple and efficient form of tap or
apparatus contrived for drawing off liquids in separate measured

page_text: The apparatus is formed with a slightly coned or tapered hollow body 1,
to be inserted into the cask or other vessel from which the liquid is to be
withdrawn, and to which it may be attached by means of a flange 2.
A hollow tapered plug 3 is fitted to work liquid-tight in the body 1,
like the plug of an ordinary tap, but with the end on which the handle 4
is formed or fixed, projecting out at the front end of the body 1, whilst
the other smaller end is inside of the cask or vessel, and is held by a
screw and nut 5 in the ordinary way. In the part of the body 1, which
is inside the cask or vessel, there are two slots 6, 7, one along the top
and the other along the bottom, and in the external part there is an air
outlet 8 at the top, and a discharge spout 9 at the bottom. The hollow
plug 3 is formed with two diametrically opposite slots 10, 11, at its
inner part, and with two holes 12, 13; at its front end, but at right angles
to the slots 10, 11. When the tap is shut as shown in Figures 4, 5, 6,
the slots 10, 11, in the plug 3, coincide with the slots 6, 7, in the body 1,
and the plug 3 becomes filled with the liquid from the cask or vessel,
the air in it escaping through the upper slots 10, 6, into the vessel, and
thereby dispensing with a vent peg. On the plug 3 being turned a
quarter round into the position in which it is shown in Figures 7 and 8,
the slots 6, 7, 10, 11, inside become closed from being at right angles to
each other, whilst the openings 12, 13, at the front end
then coincide with the air hole 8 and discharge spout 9. The contents
of the plug 3 are then at once discharged, but no more liquid can get
into it until it is again turned back into the position shown in Figures
4, 5, 6, in which the discharge spout 9 is closed. The quantity of liquid
discharged at each action will be equal to the internal capacity of the
hollow plug 3, and the body 1 and plug 3 can be made of different
sizes to give different measures.
of the plug 3,
The apparatus may be modified by making the plug 8 with two or
more separate compartments, or by increasing the number of slots. The
plug 3 and body 1 might also be made with their smaller ends out-
wards.
Having thus particularly described my said Invention, and the
manner of performing the same, I have to state that I do not restrict
myself to the precise details herein described or delineated, but that what
I believe to be novel and original, and claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the con-

page_text: structing of measuring taps substantially in the improved manner
herein described and delineated.
In witness whereof, I, the said James Millar Ure, have hereunto set
my hand and seal, this Nineteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-three.
