PROVISIONAL SPECIFICATION left by the said Frederick Baron
Michell at the Office of the Commissioners of Patents, with his
Petition, on the 1st October 1874.
I, FREDERICK BARON MICHELL, of Truro, in the County of Cornwall,
Jeweller, do hereby declare the nature of the said Invention for "AN
IMPROVED STOPPER FOR BOTTLES FOR CONTAINING GASEOUS AND OTHER LIQUIDS
WHEREBY FILLING, STOPPERING, AND OPENING SUCH BOTTLES CAN BE EFFECTED," to
be as follows:-
This Invention consists in an improved stopper for bottles.
One mode of constructing my improved stopper consists in having a
tube, at the lower part of which is a ring of rubber or other suitable

page_text: material. In this tube a slider or piston slides, free to move up or
down, such slider or piston running through a ring of rubber or other
suitable material placed in a groove in the tube. This piston or slider,
which is hollow, has an opening or openings made in same, but in some
cases the piston or slider is solid. When the liquid is required to be a
withdrawn the piston or slider is pressed or drawn and passed through
the above elastic band, and the liquid runs through the tube into and
through the openings in the piston or slider, and flows out through

page_text: My improved stopper is made of any material that may be found
suitable, and may either be fitted externally to the bottles or internally,
as may be required, but by preference internally.
My improved stopper is to secure cleanliness, safety, and prevention of

the contents in the glass without bespattering the person engaged in
pouring out the same, as well as the preservation of any quantity of the
liquid that may be left in the bottle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Baron Michell in the Great Seal Patent
Office on the 31st March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Frederick
BARON MICHELL, of Truro, in the County of Cornwall, Jeweller, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of October, in the year of our Lord
One thousand eight hundred and seventy-four, in the thirty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Frederick Baron Michell, Her special licence that I,
the said Frederick Baron Michell, my executors, administrators, and
assigns, or such others as I, the said Frederick Baron Michell, 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
STOPPER FOR BOTTLES FOR CONTAINING GASEOUS AND OTHER LIQUIDS, WHEREBY
FILLING, STOPPERING, AND OPENING SUCH BOTTLES CAN BE EFFECTED," upon the
condition (amongst others) that I, the said Frederick Baron Michell, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, 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.

page_text: 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 Frederick Baron Michell, 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:-
The objects of my said Invention are to secure cleanliness, safety, and
prevention of waste, facility in filling, easy discharge, and the security
of procuring the contents in the glass without bespattering the person
engaged in pouring out the same, as well as the preservation of any
quantity of the liquid that may be left in the bottle. These objects I
effectuate by means of an improved stopper for bottles.
One mode of constructing this improved stopper consists in having a
tube, at the lower part of which is a ring of indian-rubber or other
suitable material placed in a groove. In this tube a slider or piston
slides free to move up and down, such slider or piston running through
a ring of indian-rubber or other suitable material placed in a groove inside.
of the tube. This piston or slider, which is hollow, has an opening or
openings made in same, but in some cases the piston or slider is solid.
When the liquid is required to be withdrawn the piston or slider is
pressed or drawn and passes through the above elastic band, and the
liquid runs through the tube into and through the openings in the piston
or slider, and flows out through same.
In some cases the exit of the liquid is through holes in the outer tube,
the liquid flowing through the hollow piston or slider and out by
openings in same, thence through the holes or openings in the outer
tube, and sometimes up through the tube when the slider is depressed,
the slider only serving to close and open the stopper as required when it
is solid.
Another form of stopper consists of the tube with the inner piston or
slider running through same, passing to the extremity of the outer tube,
said piston or slider terminating in a ring of indian-rubber or other
suitable material, which when the stopper is closed presses firmly against
the bottom of the outer tube, thereby rendering it perfectly air and gas-

page_text: In Figures 3 and 4 the slider or piston is partly hollow, that in Figure 3
being in the lower part, and in Figure 4 the upper. In each of these
stoppers a groove is formed in the cylinder or tube c, into which is
inserted a ring of rubber g through which the slider or piston a works.
When opening the stopper (Figure 3) the pusher or slider a is forced down,
and when the openings e arrive below the rubber g the liquid rises in the
piston or slider a, and out at top of same. In Figure 4 the reverse action
takes place to that in Figure 3, for the piston or slider a is pulled up until
the openings e arrive above the rubber g, when the liquid flows through
openings in the slider or piston a, and thence out through openings a in
the tube or cylinder c.
In Figure 5 is a tube hollow a greater part of its length, terminating
in openings h¹. Round the upper part is another tube i, in which in a
groove is fitted rubber k. When this stopper is to be opened the tube i is
forced down till the openings are above the tube i, as shewn in the
Figure, when the liquid flows out through said openings h¹.
Figures 6 and 7 shew modifications of the arrangements herein-before
described (the same being capable of adoption in certain cases), that is
to say, I can use a piston, plunger, or slider 1, at the lower part of which
is the ring (f) of indian-rubber or other suitable material placed in a
disc or part m grooved for it to slide on. This piston, plunger, or slider
slides free to move up or down through the rubber when the bottle is
filled, without either depressing the indian-rubber or relaxing its hold on
the neck of the bottle to the full extent of the groove. The piston,
plunger, or slider, which is hollow or partly hollow, has openings n made
in part of the groove, and when the liquid is required to be drawn off
the piston, plunger, or slider is pressed down through the elastic band to
the full extent of the part grooved, and the liquid runs through the
openings into the tube or piston 1, and flows out either through a hole o
placed immediately above the groove, allowing it to burst against the
neck of the bottle to break its force before falling into a glass, or else
discharging through the top, where the opening is compressed from a
round hole into a narrow one, thus spreading the liquid over a large area
and reducing the rebound to the minimum.
For sending long distances my solid sliders have holes through which
iron wires can be placed that are held firmly against the top of the
bottle by the force with which the elastic hands draw back after raising
them for that purpose.

page_text: The hollow ones have a groove cut around them in which a curved
wire fits, effecting the same result.
When my stoppers are depressed to discharge the clastic bands con-
tracts into grooves cut for their reception, which retain them in a
discharging condition without being held by both hands until they arc
again drawn up.
Having now particularly described the nature of my said Invention,
and in what manner the same is to be performed or put in practice, I
hereby declare that I claim the Invention of an improved stopper for
bottles for containing gaseous and other liquids, whereby filling,
stoppering, and opening such bottles can be effected, as the same is
herein-before set forth and described, and illustriated by the Drawings.
In witness whereof, I, the said Frederick Baron Micheli, have
hereunto set my hand and seal, this Twenty-second day of
March, in the year of our Lord One thousand eight hundred
and seventy-five.
FREDERICK BARON MICHELL. (L.S.)
