PROVISIONAL SPECIFICATION.
Improvements in Bottling and Corking Machines.
I FREDERICK FOSTER of Niagara. Works, Eagle Wharf Road, Hoxton in
the County of Middlesex Engineer do hereby declare the nature of this invention
to be as follows:-
This invention relates more particularly to bottling and corking machines known
as lever bottling machines in which the cork driver is caused to rise and descend by
means of a lever handle operated by the bottler.
My improvements relate to means for operating a syrup pump by the movement
of the lever which governs the movement of the cork driver so that if desired a
charge of syrup may be injected into the bottle during the carly part of the move-
ment of the cork driver in its descent to rest upon the cork and drive it sufficiently
far into the conical passage through which it passes to the bottle neck to close the
upper part of the conical passage as required for admitting aërated or effervescent
liquid to be filled into the bottle.
For the syruping operation I employ an inverted syrup pump the plunger of
which is operated from below and may be caused to eject from the pump barrel
more or less syrup according to the height to which it is carried by the operating
mechanism. I carry a guide rod depending from the plunger in suitable bearings
and upon this guide rod I fix a stud carrying a friction roller. The fulcrum pin of
the lever by which the cork driver is controlled is rigidly connected with the said
lever so as to oscillate in bearings when the lever is vibrated. Upon this fulcrum
pin I secure in a manner to be rigidly connected therewith at various angles a
projecting cam plate to engage with the friction roller upon the guide rod of the
syrup-pump-plunger the angle. at which it is fixed with relation to the lever handle
determining the stroke to be given to the plunger and consequently the quantity
of syrup to be ejected from the pump barrel at each stroke.
The cam plate has a curved slot concentric with the fulcrum pin of the hand
lever during part of its course so that after the plunger of the syrup pump has
been lifted the cork driver may be further operated to drive the cork down into
the bottle mouth without affecting the syrup pump; the further course of the slot
in the cam plate is set in towards the centre of rotation thus forming a hook by
which the friction roller on the guide rod of the syrup-pump-plunger is engaged.
When the plunger of the syrup pump completes its stroke and comes to rest there
is a slight recoil and this interferes with the smooth working of the apparatus when
the cam path is represented by a curved slot in the cam plate having unyielding
walls. To obviate this I make one of the walls i.e. that which forms the hook for
lifting the syrup pump plunger, in the form of a spring jaw being hinged below and
having a coiled spring partly sunk in the jaw and partly in the backing wall from
which it recedes and to which it approaches in order to compensate for the recoil
of the syrup pump plunger hereinbefore mentioned.

Improvements in Bottling and Corking Machines.
I FREDERICK FOSTER of Niagara Works, Eagle Wharf Road Hoxton in the
County of Middlesex, 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 more particularly to bottling and corking machines known
as "leverbottling machines in which the cork driver is caused to rise and descend
by means of a lever handle operated by the bottler.
My improvements relate to means for operating a syrup pump by the movement
of the lever which governs the movement of the cork driver so that if desired, a
charge of syrup may be injected into the bottle during the early part of the move-
ment of the cork driver in its descent to rest upon the cork after driving it
sufficiently far into the conical passage, through which it passes to the bottle neck,
to close the upper part of the conical passage as required for admitting aërated
or effervescent liquid to be filled into the bottle.
In the accompanying drawings
Figure 1 is a front elevation of part of a "lever" bottling machine showing the
application of the cam for operating the syrup pump.
Figure 2 is a front elevation of the cam drawn to an enlarged scale.
Figure 3 is a plan of the underside of Figure 2.
1 employ an inverted syrup pump A, the plunger B of which is operated from
below and may be caused to eject from the pump barrel more or less syrup
according to the height to which it is carried by the operating mechanism. I
carry a guide rod C depending from the plunger, in bearings a a and upon this
guide rod C I fix a stud carrying a friction roller D. The fulcrum pin E of the
lever F by which the cork driver G is controlled is rigidly connected with the lever
F so as to oscillate in its bearings when the lever F is vibrated. Upon this
fulcrum pin E I secure a specially formed cam plate H by means of a set screw
so that it can be fastened upon the fulcrum pin E at various angles in relation with
the lever F. The changes in the inclination of the cam plate H cause the stroke
of the syrup pump to be increased or curtailed and consequently the dose of syrup
to be varied. Generally, certain regulated doses are required and in order that the
cam plate H may be readily fixed in the exact position to obtain the required dose
I make a perforation in the head of the fulcrum pin E through which a set pin J
may be passed to engage with one or other of several holes & made in the boss of
the cam plate H for the purpose of accurately setting the cam plate H in any
predetermined position.
The cam plate H has a curved slot K concentric with the fulcrum pin E of the
lever F during part of its course so that after the plunger B of the syrup pump has
been lifted the cork driver G may be further operated to drive the cork down into
the bottle mouth without affecting the syrup pump, the further course of the slot in
the cam plate H is set in towards the centre of rotation thus forming a hook by
which the friction roller D on the guide rod C of the syrup-pump-plunger B is
engaged.
When the plunger B of the syrup pump completes its stroke and comes to rest
there is a slight recoil and this interferes with the smooth working of the apparatus
when the cam path is represented by a curved slot in the cam plate H having
unyielding walls. To obviate this I provide a hinged jaw L governed by the
embedded spring M so as to move under the friction roller D to prevent any recoil
on the part of the syrup-pump-plunger B at the end of its stroke..

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 a bottling aud corking machine the cam plate H adjustably secured to the
fulcrum pin E of the lever F to engage with the plunger of a syrup pump substan-
tially as and for the purposes described.
'
2. In a cam plate, employed in the manner described in the above claiming
clause 1, the hinged jaw L accommodating the cam to avoid any recoil of the
syrup-pump-plunger at the end of its stroke substantially as described.
