AERATED BEVERAGES [A communication from abroad by Emanuel Musitzky, of
Budapesth, Hungary.]
"
The object of this invention is to obviate the disadvantages of ordinary siphon-
bottles used for aërated beverages.
Hitherto the mechanism of siphon-bottles has been made of metal such as tin,
lead, copper or bismuth, which communicates poisonous matter to the liquid
coming in contact with it. Furthermore the valve closing the mouth of the bottle
has hitherto been so imperfect that bottles filled at a pressure of from 12 to 16
atmospheres have lost so much gas as to soon afterwards have an inside pressure of
only 4 or 5 atmospheres. These defects have considerably impaired the practical
utility of such bottles.
According to the present invention all parts coming in contact with the liquid
are made of glass or caoutchouc, and rings of soft caoutchouc are used in such a
manner that a perfectly gas-tight closure is effected.
In carrying the said invention into practice I provide a glass tube extending
nearly to the bottom of the bottle as usual. At the upper part of the bottle I
secure a valve-case made of hard caoutchouc or glass and there is a piston-valve
also of hard caoutchouc. In connection with this valve there is a piston-rod of
metal, and from one side of the case extends a discharge spout of hard caoutchouc.
I also provide a curved lever of metal for operating the piston also a spring for
keeping the piston closed.

page_text: The upper head or cap is of metal and the cap to which the parts are secured
for attachment to the bottle is of the same material. Between the top of the bottle
and the base of the valve-case I place a packing sleeve of soft caoutchouc a part
of which extends inside the neck around the glass tube. In addition to this there
are two packing rings, viz an upper and a lower one, placed at parts where leakage
might otherwise occur, these rings being of soft caoutchouc.
The siphon-bottle is provided with a shoulder on which the metal attachment
to which the cap is screwed is fixed. The glass tube is held by the soft caoutchouc
sleeve. The soft caoutchouc rings fit on the piston-valve within corresponding
recesses in the case. The pressure of the gas inside the bottle forces the lower
packing-ring so firmly against its seat that no gas can escape.
If the case is made of glass it may be formed of one piece with the spout.
In filling the siphon-bottle the spout is attached to the filling apparatus and the
liquid, after the valve has been pressed down, passes through the case into the
bottle. As soon as the bottle is filled the pressure of the gas forces up the piston
and a gas-tight closure is effected by aid of the lower soft caoutchouc ring.
The upper soft caoutchoue ring prevents any escape of gas or liquid through the
upper part of the case during the filling or emptying.
To empty the bottle the lever is pressed down and thus also the valve with
the ring is forced down and opens the passage to the spout thus allowing the liquid
to escape under the pressure of the gas in the bottle

HENRY HARRIS LAKE, of the firm of Haseltine Lake and Co, Patent Agents,
Southampton Buildings London "IMPROVEMENTS IN SIPHON BOTTLES FOR
AERATED, BEVERAGES' A communication from abroad by Emanuel Musitzky, of
Budapesth, Hungary.

This Invention relates to improvements in siphon-bottles for aërated beverages.
Hitherto the mechanism of siphon-bottles has been constructed of metal such as
tin, lead, copper or bismuth, which communicate poisonous matter to the liquid
coming in contact with them. Furthermore the valve closing the mouth of the
bottle has hitherto been so imperfect that bottles filled at a pressure of from 12 to
16 atmospheres have lost so much gas, as to soon afterwards have an internal
pressure of only 4 or 5 atmospheres. These defects have considerably impaired the
practical utility of such bottles.
The object of this invention is to obviate these disadvantages
According to the said invention all parts coming in contact with the liquid are
made of glass or caoutchouc; rings of the latter are used in such a manner that a
perfectly gas-tight closure is effected.
In the accompanying drawing a represents a bottle, b a glass-tube, c the valve
case made of hard caoutchouc or glass, & the piston-valve of hard caoutchouc, d³ the
piston-rod of metal, e the spout of hard caoutchouc, fa metal lever for operating
the valve, ga spring for keeping the piston closed, h the metal head or cap,
metal collars, ka packing sleeve of soft caoutchouc, and the lower, and m the
upper packing ring, also of soft caoutchouc.
2
The siphon-bottle a is provided with a shoulder on which the metal attachments
ii to which the other parts are attached is fixed. The glass tube b is held by the
soft caoutchouc sleeve k. The soft caoutchouc rings and m fit into recesses in
the piston-valve d and upon seats in the case c. The pressure of the gas inside
the bottle forces the packing-ring so firmly against its seat that no gas can
escape.
If the case e is made of glass, the spout e may be formed in one piece with it.
In filling the siphon-bottle, the spout e is attached to the filling apparatus, and
the liquid, after the valve d has been pressed down, passes through the case c into
the bottle. As soon as the bottle is filled, the pressure of the gas forces up the
piston-valve d against its seat and a gas-tight closure is effected by aid of the soft
caoutchouc ring. The upper soft caoutchouc ring m prevents any escape of gas
or liquid through the upper part of the case c during the filling or emptying of the
bottle.
To empty the bottle the lever fis pressed down and thereby the valve d with
the ring is forced down and opens the passage to the spout e, thus allowing the
liquid to escape under the pressure of the gas in the bottle.
Having thus fully described the said invention, as communicated to me by my
foreign Correspondent, and the manner of performing the same, I wish it
understood that I claim, in a siphon bottle:―
First. The general construction and arrangement of the packing, the piston-

page_text: valve, the valve-case, and the spout, whereby all parts coming into contact with
the aërated liquid are made of glass or caoutchouc, substantially as set forth.
Second. The combination of the piston-valve d, with the packing rings made of
soft caoutchouc, substantially as described.
In witness whereof I the said Henry. Harris Lake have hereunto set my
hand and seal this Twenty fifth day of September in the year of our Lord
One thousand eight hundred and eighty.two.
