PROVISIONAL SPECIFICATION.
A Device for Facilitating the Charging of Bottles with Aerated
Liquids.
I, WILLIAM PRIESSNITZ BONWICK, of 59 Blomfield Road, Paddington, in the
County of London, Tutor, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to a device, hereinafter called a filler, capable of
being readily applied to bottle filling machines of the kind used for filling with
aerated liquids, bottles that are to be closed by corks, and commonly called cork
racks, whereby such machines can be readily adapted for charging bottles provided
with stoppers or closures of the kind described in the Specifications of Letters
Patent No. 11,674 of 1889 and 19,806 of 1889, or other stoppers of a similar
nature.
The filler comprises a perforated tube fitted with a spring plunger and having
at one end a mouth piece and an annular elastic seat against which the mouth
of a bottle can be pressed during filling. The tube is of such a diameter that it
can be pressed through the tapered thimble and mouth piece of the filling machine
and is provided externally with a packing ring that may advantageously be a piece
of india rubber tubing, a metal washer or sleeve freely movable along the tube and
arranged to bear against the packing ring, and a screw nut to act against the
washer or sleeve. The arrangement is such that when the tube has been passed
through the said thimble with a packing ring between the lower part of the tube
and the mouth piece of the machine, and the packing ring or tubing placed
between the upper parts of the tube and thimble then by tightening the nut, the
packing ring or tubing will be caused to close the annular space between the tube
and thimble, at a point above the perforations in the tube, and the filler will be
firmly held in position for use, a gas tight joint between the lower part of the filler
and the mouth piece of the machine being ensured by the packing ring placed
between these parts. The spring plunger works tightly through packing material
placed between a shoulder within the tube and a metal washer against which bears
one end of a coiled spring that surrounds the plunger and the other end of which
bears against a guiding collar on the plunger. At one end of the plunger is a nut
that serves to press inward the stopper of a bottle during filling, the plunger for
this purpose being depressed by the plunger of the machine. A knob or collar on
the upper end of the spring plunger serves, by coming in contact with the top of
the tube, to limit the downward movement of the plunger and the consequent
depression of the bottle stopper, and the nut on its lower end serves to limit its
upward movement.

I, WILLIAM PRIESSNITZ BONWICK, of 59 Blomfield Road, Paddington, in the
_ County of London, Tutor, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has reference to a device, hereinafter called a filler that is
capable of being readily applied to bottle filling machines of the kind used for
filling with aerated liquids, bottles that are to be closed by corks, and commonly
called cork racks, whereby such machines can be readily adapted for charging
bottles provided with stoppers or closures of the kind described in the Specifications
of Letters Patent No. 11,674 of 1889 and 19,806 of 1889, or other stoppers of a
similar nature.
In the accompanying drawings
Fig. 1 is a vertical section of a filler constructed according to this invention.
Fig. 2 is an elevation, partly in section, to a smaller scale, of so much of a bottle
filling machine of the kind referred to, as is necessary to illustrate the application
thereto of the filler.
The filler comprises a perforated tube 1 fitted with a spring plunger 2 and
having at one end a mouth piece 3 and an annular elastic seat 4 against which the
mouth of a bottle can be pressed during filling as shewn in dotted line. The tube
is of such a diameter that it can be passed through the tapered thimble 5 and
mouth piece 6 of the filling machine, and is provided externally with a packing
ring 7 that may advantageously be a piece of india rubber tubing; a metal washer
or sleeve 8 freely movable along the tube and arranged to bear against the packing
ring 7; and a screw nut 9 to act against the washer or sleeve. As will be seen the
arrangement is such that when the tube 1 has been passed through the said
thimble with a packing ring 10 between the enlarged lower part 1 of the tube 1
and the mouth piece 6 of the machine, and the packing ring or tubing 7 between the
upper parts of the tube 1 and thimble 5, then by screwing down the nut 9, the
packing ring or tubing 7 will be caused to form a gas tight joint between the tube
and thimble at a point above the perforations 1 in the tube, and the tube 1 will
be drawn upward through the thimble so that the filler will be firmly held in
position for use, a gas tight joint between the lower part of the filler and the
mouth piece of the machine being ensured by the packing ring 10 placed between
these parts. The spring plunger 2 works tightly through a packing ring 11 of
suitable material such as leather or india rubber placed between a shoulder 11ª
within the tube and a metal washer 12 against which bears one end of a coiled
spring 13 that surrounds the plunger, and the other end of which bears against
a guiding collar 14 fixed on the plunger. At the lower end of the plunger is a
nut 15 that serves to press inward a stopper of the kind herein referred to during
the filling of a bottle fitted with such a stopper, the spring plunger 2 for this
purpose being depressed by the plunger 16 of the filling machine as shewn in
dotted lines in Fig. 1. A knob or collar 17 on the upper end of the spring
plunger serves, by coming in contact with the top of the tube 1 to limit the
downward movement of the plunger and the consequent depression of the bottle
stopper, and the nut 15 on its lower end serves to limit the upward movement of
the plunger.
When the nut 15 is depressed by the spring plunger, liquid under pressure
supplied by the inlet pipe 18 passes through the perforations 1b in the tube 1 and
thence into the bottle past the depressed stopper therein. Instead of using a
rubber ring 10 to secure a tight joint between the enlarged lower part 1ª of the
tube and the mouth piece 6 of the ring, the lower end of the tube may be

perforations 1b and the shoulder 11ª would of course have to be made higher up the
tube. In this case also the mouth piece 3 and seat 4 may be dispensed with,
the mouth of a bottle being filled being then held against the india rubber
washer 10 which is ordinarily used for this purpose.
The bottle filling machine or cork rack is of the ordinary construction and
comprises a casting 19 into which the thimble 7 is screwed and which is formed
with the inlet passage 19" for liquor under pressure; the standard or support 20
to which the casting 18 is secured; the hand operated plunger 16 ordinarily
employed for forcing corks into the mouths of filled bottles, but serving in the
present case to depress the spring plunger 2; and the treadle 21 with bottle
support 22 whereby a bottle is held in position to be filled.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A device or filler adapted to be readily applied to a bottle filling machine of
the kind herein referred to and comprising a perforated tube fitted with a plunger
and of such length as to extend through the thimble of the bottle filling machine,
one end of such tube being enlarged to take a bearing against the filling machine
and its other end being provided with a packing ring to close the space between
the tube and the upper end of the thimble and with means such as a sleeve or
short flanged tube and nut for compressing the said packing ring to form a gas tight
joint between the perforated tube and thimble and for securing the said tube in
place within the said machine substantially as herein described.
2. A device or filler for facilitating the charging of bottles with aerated liquids,
constructed and arranged substantially as herein before described with reference to
and shown in Fig. 1 of the drawings annexed.
