Year: 1880

page_text: LETTERS PATENT to Thomas Walker, of No. 32, Sumner Road, Croydon, in
the County of Surrey, Mineral Water Manufacturer, for an Invention of
"IMPROVEMENTS IN CLOSING BOTTLES USED FOR CONTAINING AERATED
LIQUIDS AND SUCH LIKE."
PROVISIONAL SPECIFICATION left by the said Thomas Walker at the
Office of the Commissioners of Patents on the 2nd September 1880.
THOMAS WALKER, of No. 32, Sumner Road, Croydon, in the County of Surrey,
Mineral Water Manufacturer. "IMPROVEMENTS IN CLOSING BOTTLES USED FOR
CONTAINING AERATED LIQUIDS AND SUCH LIKE.'
The object of the Invention is to provide a bottle suitable for containing aerated
or other liquids, which can be made at less price than the specially shaped bottles
fitted with internal stoppers now commonly used, but which, like them, can be used
over and over again, so that a new cork is not required each time they are filled,
as is the case when ordinary corks are used.
For this purpose I mould the head of a bottle which projects around the exterior
of the end of the neck (whilst the glass of which it is composed is in a heated and
plastic state) with two (or it might be more) slots through it on opposite sides and
lengthwise of the bottle. The under edge of each of the parts of the head left
projecting from the neck of the bottle is made square to the neck, and to incline
to its axis so as to form as it were parts of screw threads, each passing partly
around the neck.
To close the mouth of the bottle a cap, which may be of metal, glass, or other
material is placed over it. In the cap is a disc of cork to come between it and the
end of the lead; projecting inwards from two opposite sides of the cap are two
pins. When the bottle has been filled with aerated or other liquid under pressure
by any ordinary bottling machinery the cap is quickly placed on to the head of
the bottle; the two pins on the cap passing down through the two slots in the
head. A partial turn is then given to the cap whereby the pins are brought
against two inclines, and the cap is thereby drawn down tightly against the head
and the cork disc is nipped between them and a tight joint obtained.
The advantages obtained by closing bottles for containing aerated or other
liquids in the above manner are, that the joint is obtained by the use of cork
instead of vulcanized india rubber, as commonly used when the bottles are fitted
with internal stoppers. The bottles also can be cleaned just as easily as ordinary
soda water bottles, and if the caps are mislaid or lost they can easily be fitted with
another one, or the bottle can be closed by an ordinary cork.

THOMAS WALKER, of No. 32, Sumner Road, Croydon, in the County of Surrey,
Mineral Water Manufacturer. "IMPROVEMENTS IN CLOSING BOTTLES USED FOR
CONTAINING AERATED LIQUIDS AND SUCH LIKE,”
The object of the Invention is to provide a bottle suitable for containing aerated
or other liquids, which can be made at less price than the specially shaped bottles
fitted with internal stoppers now commonly used, but which, like them, can be used
over and over again, so that a new cork is not required each time they are filled, as
is the case when ordinary corks are used.
For this purpose 1 mould the head of a bottle which projects around the exterior
of the end of the neck (whilst the glass of which it is composed is in a heated and
plastic state) with two (or it might be more) slots through it on opposite sides and
fengthwise of the bottle. The under edge of each of the parts of the head left
projecting from the neck of the bottle is made square to the neck and to incline
to its axis, so as to form as it were parts of screw threads each passing partly
around the neck.
To close the mouth of the bottle a cap, which may be of metal, glass, or other
material is placed over it. In the cap is a disc of cork to come between it and the
end of the head, and projecting inwards from two opposite sides of the cap are two
pins. When the bottle has been filled with aerated or other liquid under pressure
by any ordinary bottling machinery the cap is quickly placed on to the head of
the bottle, the two pins on the cap passing down through the two slots in the head.
A partial turn is then given to the cap whereby the pins are brought against the
two inclines, and the cap is thereby drawn down lightly against the head and the
cork disc is nipped between them and a tight joint obtained.
The advantages obtained by closing bottles for containing aerated or other
liquids in the above manner are that the joint is obtained by the use of cork
instead of vulcanized india rubber, as commonly used when the bottles are fitted
with internal stoppers. The bottles also can be cleaned just as easily as ordinary
soda water bottles, and if the caps are mislaid or lost they can easily be fitted with
another one, or the bottle can be closed by an ordinary cork.
Having thus described the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view of a bottle formed as above described; Figure 2
shews a section of a cap for closing the mouth of the bottle; Figure 3 shews a side
view of a pair of tongs suitable for moulding the slots and inclines upon the
exterior of the head of the bottle; these tongs are as usual formed so that they
may be grasped in the hand, and so that the extremities of the two spring arms A
may be pressed towards one another; they are also as usual formed with a central
stem B, the end of which is of a diameter to enter the mouths of the bottles which
are to be headed. This stem B also carries a plate C for the end of the neck of a
bottle to rest against whilst a head is being moulded around it. On the extremity
of noch an
All T. then all
the and

page_text: other of a series of short studs G, which project from the back end of the rollers
and which are ranged equidistantly around them; when the projections upon the
bolts are between some or other of the studs G upon the rollers, the rollers are
locked and prevented from turning; but when the spring arms of the tongs
are squeezed inwards towards one another the ends of the bolts E come against the
plate C and are stopped from moving, whilst the arms and rollers carried by them
continue to approach one another; the studs on the rollers are thereby carried
clear of the projections on the bolts, and the rollers are then free to turn.
In the circumference of each of the rollers indentations are formed, of a shape
corresponding with the form of the projections which are to be moulded upon the
exterior of the heads of the bottles. The two rollers are set to correspond with one
another, so that a projection moulded on the exterior of the head of a bottle by an
indentation in one roller shall as the bottle is turned enter a corresponding
indentation in the other roller.
When a quantity of hot
"
metal sufficient to form the "ring" or "head" of a
bottle has been gathered around the end of the neck in the ordinary manner, the
end of the neck with the metal around it is grasped by the tongs, and as soon as
the rollers commence to bear against the "metal" which is around the neck the
rollers get unlocked and are free to turn. The shaping of the head by means of
the tongs is then proceeded with in the ordinary manner. When the head is com-
pleted, and the rollers are no longer held up against it, the spring arms of the tongs
move away from one another, and the rollers, which still remain in positions corre-
sponding with one another, are again locked and held by the locking bolts, and are
ready to be used for shaping the head on another bottle.
The caps used for closing over the mouths of bottles moulded as above described,
with inclines around the head, I preferably form of metal, as shown at Figure 2.
At the bottom of the cap is placed a disc of cork H, and in the sides of the cap at
two opposite points indentations I are made. so as to form projections on the
interior of the cap, or these projections on the interior of the cap might be otherwise
formed. When the bottle is to be closed the cap is placed on to the head, the two
projections I on the inside of the cap pass down through the two longitudinal
slots J, which are moulded in the head, and when a partial turn is given to the cap
the projections H pass under the ends of the inclines K, and the cap is by the
inclines drawn tightly against the end of the head and the cork disc is nipped
between them and a tight joint so obtained.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that-
I claim, the closing of glass bottles by moulding the exterior of the head of each
bottle, whilst the glass of which the head is composed is in a heated and plastic
state, with two or more longitudinal slots or depressions through it, and with the
under side of each of the parts of the head, which are left projecting, made to form
inclines, by means of which a cap may be drawn against and held over the mouth
of the bottle, substantially as described.

and seal, this Second day of March, in the year of our Lord One thousand
eight hundred and eighty one
