page_text: LETTERS PATENT to Frederick Foster of 26 Eagle Wharf Road Hoxton
London in the County of Middlesex for an Invention of "AN IMPROVED
MACHINE FOR FILLING AND SYRUPING INTERNALLY STOPPERED BOTTLES FOR
CONTAINING AËRATED LIQUIDS”
PROVISIONAL SPECIFICATION left by the said Frederick Foster at the
Office of the Commissioners of Patents on the 18th October 1883.
FREDERICK FOSTER of 26 Eagle Wharf Road, Hoxton London, in the County of
Middlesex “AN IMPROVED MACHINE FOR FILLING AND SYRUPING INTERNALLY
STOPPERED BOTTLES FOR CONTAINING AÈRATED LIQUIDS '
25
This Invention relates to that class of filling machines in which means are
provided for inverting the bottle when filled for the purpose of causing the
stopper to fall to its seating in the neck of the bottle. The object is to simplify
the operation of syruping the bottle previous to turning on the supply of aërated
liquid and to provide an improved means of regulating the charge of syrup
delivered at each stroke of the pump. For this purpose I mount upon a hollow
metal column the usual revolving trunnion bearing the bottle carriage and above
the said trunnion I fix in an inverted position & syrup pump capable of being
operated by means of a fixed cam upon the revolving trunnion The return stroke
of the pump is performed by a coiled spring surrounding a rod extending from the
plunger of the pump through the pump at the top passing through a packed gland
and a guide above for ensuring the true vertical movement of the plunger. At
the upper extremity of the said guide rod is a thumb screw by means of which the
position of the plunger of the syrup pump may be regulated within the pump
barrel so as to control the quantity of syrup delivered at each stroke of the pump.
By inverting the syrup pump I am able to use a plunger & hydraulic cup leather
within a blown glass barrel because sufficient syrup always remains in the barrel
to keep the leather moist & exclude air. By this means all the advantages of the
use of a glass barrel in connection with a syrup pump are obtained without
incurring the necessity for boring the glass barrel which occurs when the pump is
fitted with a piston & bucket leathers.

"AN IMPROVED MACHINE FOR FILLING AND SYRUPING INTERNALLY STOPPERED
BOTTLES FOR CONTAINING AERATED LIQUIDS
"
This invention relates to that class of filling machines in which means are
provided for inverting the bottle when filled for the purpose of causing the stopper
to fall to its seating in the neck of the bottle. The object is to simplify the
operation of syruping the bottle previous to turning on the supply of aërated
¿liquid and to provide an improved means of regulating the charge of syrup
delivered at each stroke of the pump. For this purpose I mount upon a hollow
metal column the usual revolving trunnion A bearing the bottle carriage which is
of the kind ordinarily used with this class of filling machine and is not shewn in
the drawings accompanying this specification. Above the said trunnion' A I fix
in an inverted position a syrup pump B capable of being operated by means of a
fixed cam C upon the revolving trunnion A The return stroke of the plunger F
of the pump B is performed by a coiled spring D surrounding a rod E extending
from the plunger F of the pump B through the pump B at the top, passing through
a packed gland or stuffing box G and a guide H above for ensuring the true
vertical movement of the plunger F At the upper extremity of the guide rod E
is a thumb screw I by means of which the position of the plunger F of the syrup
pump B may be regulated within the pump barrel K so as to control the quantity
of syrup delivered at each stroke of the pump plunger F By inverting the syrup
pump B I am able to use a plunger F and hydraulic cup leather L within a blown
glass barrel K because sufficient syrup always remains in the barrel K to keep the
leather moist and exclude air. By this means all the advantages of the use of a
glass barrel in connection with a syrup pump are obtained without incurring the
necessity for boring the glass barrel which occurs when the pump is fitted with a
piston and bucket leathers. In the accompanying drawings Fig I represents a
sectional elevation of the upper part of a filling machine such as I have described
suitable for bolting down upon a bench or on an ornamental iron column. Fig 2
represents an end view at right angles to the view represented by Fig I with part
of the casting removed to expose a full view of the cam C acting upon a friction
roller M at the extremity of the guide rod E In both figures the same letter is
used to denote the same part. In Fig IN is the stop valve connected with the :
outlet passage O. from the syrup pump B. P is the inlet for aërated liquid to the
trunnion A in advance of the stop valve N of the syrup pump B. Q is an
hydraulic cup leather to prevent leakage at the end of the trunnion A. In Fig 2
Ris the valve box containing the draught valve controlling the passage forming
the inlet to the pump B. Having thus described the nature of my said invention
and the manner in which the same is to be performed particularly by reference to
the drawings hereunto annexed I would have it understood that I do not claim the
combination of a syrup pump operated by a cam or eccentric upon the trunnion of
a filling machine but what I do claim is
1° The arrangement described and illustrated whereby the length of the stroke of
the plunger may be varied by a simple adjustment of the thumb screw I.

page_text: 2° The syrup pump as described with valve box and stuffing box at the upper part
and opening to receive the plunger from underneath for the purposes described.
In witness whereof I the said Frederick Foster have hereunto set my hand
and seal this eighteenth day of April in the year of Our Lord One thousand
eight hundred and eighty four
