Improvements in and in Apparatus for Filling Syphons and the like
with Aerated Water and Flavouring Syrup.
I, CHARLES WILLIAM CARTER, of 1, Buckingham Street, Liverpool, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows:
This invention relates to the mode of and apparatus for filling syphons and the
like with flavouring syrup and aerated water, the objects being, to obviate the
necessity of "snifting" which is at present resorted to in order to allow the air
to escape as the syphon is filled and which results in considerable waste, and to
provide a compact and easily worked apparatus by means of which the syphon
is held in position, its valve opened, after which it is charged with the appropriate
amount of syrup and aerated water.
In charging the syphon, instead of "snifting" the contained air, from time to
time as the aerated water is introduced into the inverted syphon as is usual accord-
ing to present practice, I place the syphon in an upright position and compress
the air to about one fourteenth or one fifteenth of its original volume by using
the full pressure of the aerated water in charging. By this means I am enabled,
without withdrawing any air, to charge the syphon with the usual quantity of
liquid.
The apparatus for charging the syphons comprises the following:-a device for
holding the syphon in position which when operated automatically opens the
valve of the syphon: a coupling device which makes a fluid-tight joint between
the nozzle of the syphon and the delivery pipe of the apparatus: a pump by means
of which a definite measurable quantity of the appropriate syrup is introduced:
and a suitable regulating cock and connection to control the supply of the aerated
water.
In an apparatus as constructed according to my invention these several parts are
mounted on a suitable bracket or frame on the base of which is a vertically adjust-
able stand which supports the syphon at the proper height. Vertically over the
stand, and carried by the frame, is a plunger operated by a lever, which latter is
controlled by a spring which keeps the plunger normally in its uppermost posi-
tion; as the plunger is caused to descend by a downward. pull on the lever or by
operating the latter by means of a treadle, it comes into contact with the top of
the syphon, and as it is connected to the lever by an interposed spring, the lever
can continue its downward motion whilst an elastic pressure is exerted on the
syphon: the further descent of the lever opens the valve of the syphon by engage-
ment with the handle thereof.
"
"
When the syphon is placed on its stand the nozzle thereof is inserted in the
or
cup
coupling device which consists of a.
"hat" washer contained in a union
piece and pressed into contact with the nozzle by a spring pressed taper thimble;
the latter serves to provide a sufficient initial pressure to ensure a joint in the first
instance, and the washer is so arranged that when it is subjected to the pressure

page_text: of the syrup and aerated water it prevents leakage after the manner of a Bramah
collar.
The coupling device serves to connect the interior of the syphon to the delivery
pipe which is connected to the aerated water supply tank by means of a controlling
cock.
The syrup pump is interposed between the supply pipe (on the syphon side of
the aerated water control cock) and the syrup tank, and is provided with suction
and delivery valves. The plunger is operated by a lever the lift of which can be
regulated to determine the amount of syrup injected at each stroke.
The action is as follows:-the syphon is placed in position with its nozzle in
the coupling device and the lever of the holding device is depressed, this action
secures the syphon in position and opens the valve thereof. The syrup pump is
now operated and charges the syphon with the proper amount of syrup, then the
cock controlling the supply of aerated water is opened and the syphon is charged
with the latter which as it passes in carries with it any syrup on the delivery
side of the delivery valve, and having a pressure of, say, 200 pounds per square
inch it compresses the air in the syphon as described.
In some cases it may be desirable to get rid of the air by "snifting" in which
case the apparatus may be modified by arranging the syphon in an inverted posi-
tion and providing a suitable snifting valve.

Improvements in and in Apparatus for Filling Syphons and the like
with Aerated Water and Flavouring Syrup.
I, CHARLES WILLIAM CARTER, of 1, Buckingham Street, Liverpool, in the
County of Lancaster, Engineer, 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 relates to the mode of and apparatus for filling syphons and the
like with flavouring syrup and aerated water, the object being to provide a com-
pact and easily worked apparatus by means of which the syphon is held in position,
and its valve opened, after which it is charged with the appropriate amount of
syrup and aerated water.
The apparatus for charging the syphons comprises the following; a device
for holding the syphon in position, which when operated, automatically opens the
valve of the syphon; a coupling devica which makes a fluid-tight joint between
the nozzle of the syphon and the delivery pipe of the apparatus; a pump by means
of which a definite measurable quantity of the appropriate syrup is introduced;
and a suitable regulating cock and connection to control the supply of the aerated
water.
I have illustrated my invention in the accompanying drawings, in which Fig. I
is an elevation of the apparatus, partly in section on the line A, A, of Fig. III;
Fig. II is a fragmentary section on the line B, B, of Fig. I, Fig. III is a side
elevation looking in the direction of the arrow C Fig. I; Fig. IV is a side eleva-
tion looking in the direction of the arrow D, Fig. I; and Fig. V is a medial
section, to a larger scale, of the coupling device. With the exception of the
frame, the parts shown in Fig. III are omitted in Fig. IV, and vice versa.

page_text: Throughout the drawings the same parts are indicated by the same reference,
figures, and in the case of sections, the direction in which they are viewed is indi-
cated by the small arrows placed adjacent to the letters denoting the plane of
section.
1 is the frame from which the several parts are carried, 2 is the vertically adjust-
able stand which supports the syphon 3 at the proper height. Vertically over
the stand is a plunger 4, operated by a lever 5, which latter is controlled by a
spring 6 which keeps the plunger normally in its uppermost position; the plunger
is elastically connected to the lever by means of the spring 7 and the hollow
sliding piece 8 within which the spring is compressed when, as the sliding piece
descends, the plunger comes into contact with the syphon. The sliding piece is
provided with a projecting piece 9 adapted, as the sliding piece descends, to open
the valve of the syphon, the latter being held in position by the elastic plunger
and having its nozzle inserted in the coupling device 10. The coupling device,
which is shown in section in Fig. V, is used to connect the syphon nozzle 3¹ to the
delivery pipe 11 and is fitted with a cup" or hat" washer 12 contained in a
union piece and pressed into contact with the nozzle by a spring pressed taper
thimble 13 which serves to provide a sufficient initial pressure to ensure a joint in
the first instance; the washer 12 is flexible and so arranged that when it is sub-
jected to the pressure at which the syphon is being charged it prevents leakage,
after the manner of a Bramah collar."

The delivery pipe 11 is connected to a syrup pump 14 by the passage 15, a non-
return valve 16 being interposed; the pump draws in its charge of syrup through
the nine 17 which is connected to the syrup supply tank, a non-return valve 18
being interposed between the pump and the said pipe 17, and it will be seen from
Figs. I and II that the valves 16 and 18 act respectively as delivery and suction
valves for the pump; the pump, as shown, is preferably provided with a glass
cylinder. The plunger 14' of the pump is operated by a lever 19, and a spring 19'
is attached to the end of the lever and tends to raise the plunger, the travel of the
latter being regulated by the position of the nut 20 on the screw 21 which screw
is pivoted to the lever as shown in Fig. III. The plunger is graduated so that its
travel can be adjusted to deliver the appropriate quantity of syrup at each stroke.
The apparatus as described so far is adapted for syruping the syphons, and it
may also be used for supplying the aerated water thereto if the pressure of the
latter be sufficient to force the proper quantity into the syphon without the
necessity of "snifting," in which case the aerated water supply is connected
through a suitable controlling cock to the passage 22. Usually however this is
not the case and I have found this method of charging unsatisfactory, and
"snifting" has accordingly to be resorted to; in the latter event it is of course
necessary to invert the syphon, in which case the positions of the stand 2 and the
plunger 4 with its sliding piece and lever are reversed, and the coupling device
is modified to suit the new position of the syphon nozzle; the aerated water con-
trol cock is modified, in a manner well known to those conversant with this class
of apparatus, so that when the svphon receives a certain charge of aerated water
the supply cock is closed and the upper portion of the interior of the inverted
syphon opened to the atmosphere through the snifting valve to get rid of the com-
pressed air.
The action of the apparatus is as follows:
The syphon is placed in position with its nozzle in the coupling device and the
lever 5 is depressed. this action secures the syphon and opens the valve thereof.
The syrup pump is then operated and charges the syphon with the proper quantity
of syrun where the apparatus is used to charge the syphon with aerated water.
the cock controlling the latter is operated as soon as the syphon has been charged
with syrup, the snifting valve being used in conjunction with the controlling
cock when the apparatus is modified to charge the inverted syphons: or of course
the apparatus may be used to charge the syphons with syrup only.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In apparatus for filling syphons and the like with aerated water and flavour-
ing syrup, the improved coupling device, which consists of a flexible washer which
fits the syphon nozzle and which is initially pressed into contact therewith by a
spring pressed taper thimble and afterwards by the charging pressure; substan-
tially as described and illustrated.
2. In apparatus for filling syphons and the like with aerated water and flavour-
ing syrup, the improved device for holding the syphon in position and opening
the valve thereof, which consists of a lever elastically connected to a plunger
adapted to hold the syphon in position, and rigidly connected to a sliding piece
carrying a projection which engages with the syphon valve and opens it after
the syphon is held in position; substantially as described and illustrated.
3. The improved apparatus for filling syphons and the like with aerated water
and flavouring syrup, substantially as described and illustrated.
