LETTERS PATENT to George Wilson, of the City of York, Glass Manu-
facturer, for the Invention of "AN IMPROVED CONSTRUCTION OF STOPPERED
BOTTLE."
Sealed the 27th March 1861, and dated the 6th November 1860.
PROVISIONAL SPECIFICATION left by the said George Wilson at the
Office of the Commissioners of Patents, with his Petition, on the 6th
November 1860.
I, GEORGE WILSON, of the City of York, Glass Manufacturer, do hereby
declare the nature of the said Invention for "AN IMPROVED CONSTRUCTION
OF STOPPERED BOTTLE," to be as follows:-
The object of this Invention is to regulate the flow of liquids from bottles,
more especially so those intended to contain strong or poisonous medicines.
The body of the bottles may be of any desired shape, but for those destined to
hold poisons I prefer the form now so generally approved, viz., the conical
octagon. The neck and brim of the bottle is provided with two spouts or
projections opposite to each other, and of different dimensions. The larger
one can be used to pour liquid from the bottle in large quantities, whilst from
the smaller spout or projection it is intended that the liquid shall issue only in
minims or drops. Into the neck of the bottle is fitted air-tight a solid glass
stopper, and on the opposite sides of the stopper, and for a given distance up
the sides two small grooves are formed to constitute vents or passages for the

page_text: liquid without withdrawing the stopper from the neck of the bottle. To open
such a vent the stopper has to be turned to bring a groove in a line with a
spout of the bottle. Then on the bottle being inclined the liquid will be free
to issue forth either in a stream or in minims or drops, as the operator may
require. To close the bottle it is only requisite to turn the stopper partially
'round. The necks and brims I form in the act of blowing the bottle.
*SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Wilson in the Great Seal Patent Office on the
6th May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WILSON, of the City of York, Glass Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of November, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Wilson, Her special license that I, the said George Wilson, my
executors, administrators, and assigns, or such others as I, the said George
Wilson, 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 "AN IMPROVED CONSTRUCTION
OF STOPPERED BOTTLE," upon the condition (amongst others) that I, the said
George Wilson, by an instrument in writing under my hand and seal, 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 George Wilson, 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,
reference being had to the Drawing hereunto annexed, and to the letters and
figures marked thereon (that is to say):-
The object of this Invention is to provide a means for regulating the flow of
liquids from stoppered bottles, more especially those intended to contain strong
or poisonous medicines. The body of the bottles may be of any desired shape,

page_text: but for those destined to hold poisons I prefer the form now so generally
approved, viz., the conical octagon. The neck and brim of the bottle is
provided with two spouts or projections opposite to each other, and of different
dimensions, the larger one being used when it is required to pour liquid from
the bottle in a continuous stream, whilst the smaller spout or projection is
intended to discharge the liquid in minims or drops. Fitted air-tight to the
neck of the bottle thus constructed is a solid glass stopper, grooved or
channelled at opposite sides of its periphery to form vents or passages for the
discharge of liquid when brought into coincidence with the spouts on the
bottle neck.
In the accompanying Drawing, Fig. 1 shews the improved bottle in side
elevation; Fig. 2 is a vertical section of the same; and Figs. 3 are longitudinal
and cross sections of the stopper detached from the bottle.
a is the spout from which to pour a continuous stream, and 6 the spout for
discharging the liquid drop by drop. To form a channel for the liquid to the
spout a I prefer to grind a portion of the periphery of the stopper flat, as
shewn at a, Fig. 3; and for the passage of the liquid to the dripping spout b
I cut a groove in the stopper, as at 6*. It will be seen that neither of these
channels extend the whole length of the ground or cylindrical portion of the
stopper, but that the channel a* terminates short of the shoulder of the stopper
and the channel 6* short of the bottom of the stopper. By this arrangement
when the channels are turned out of coincidence with the lips a and b, the
bottle will be stoppered air-tight. In order to give the liquid in the bottle
access to the groove or channel 6*, when the contents of the bottle are
required to be discharged in minims I mould a recess in the neck of the
bottle, as shewn at c, so that when the groove 6* is brought into coincidence
with the spout 6 there will be a free passage for the liquid from the interior of
the bottle to that spout. It will now be understood that when it is required
to withdraw liquid from a bottle thus stoppered there will be no necessity for
withdrawing the stopper from the neck of the bottle, but that to open the
discharge vents the stopper has merely to be turned to bring the grooves or
channels thereof in a line with their respective spouts on the bottle neck.
Then, on inclining the bottle, the liquid will be free to issue forth either in a
stream or in minims or drops, according to which of the spouts the operator
may depress. When a sufficient quantity of liquid has been discharged it
is only requisite in order to close the bottle to turn the stopper partially
round in its seat. The spouts or projections I form in the act of blowing
the bottle.

Having now set forth the nature of my Invention of an improved con-

page_text: struction of stoppered bottle, and explained the manner of carrying the same
into effect, I would remark that it has already been proposed to provide
stoppered bottles with a means of discharging their liquid contents in minims
by providing a contracted discharge passage; I do not therefore intend to
claim the principle of a removable contracted passage for impeding the
discharge of the liquid contents of stoppered bottles; .but I claim under the
above in part recited Letters Patent constructing stoppered bottles in the
manner and for the purpose above set forth.
In witness whereof, I, the said George Wilson, have hereunto set my,
hand and seal, the Fourth day of May, in the year of our Lord One
thousand eight hundred and sixty-one.
GEO. WILSON. (L.S.)
