An Improved Machine for Filling Bottles with Liquids.
We, GEORGE GALBRAITH, Cabinet Maker and FRED WALLIS, Pattern
Maker, both of Platt Street, Rochester, Monroe County, New York State, U.S.A.,
do hereby declare the nature of this invention to be as follows :-
In
This invention comprises a container for the liquid to be filled into bottles. The
bottom of the container slopes downwards from the centre to the circumference
and near the latter has orifices into which are screwed sockets, into the lower end
of which the necks of the bottles to be filled are entered and held therein by
means of spring clamping levers mounted upon the outside of the sockets. Within
each socket is carried a sliding filling tube held normally pressed down by a spring
located between the top of the socket and a shoulder upon the filling tube.
operation the neck of a bottle is pressed upwards into the socket, the filling tube
thus forced upwards to uncover an orifice in the same which places it in com-
munication with the container so as to fill the bottle. In doing this a valve is
pressed upwards to close the bottom of the filling tube and shut off the supply of
liquid. The bottle is then withdrawn when the filling tube is pressed down by the
spring to close its communication with the container. Vent holes are provided for
the discharge of air from the bottles and through the sockets. The container is
carried upon a frame and may be rotated upon a central vertical shaft.

An Improved Machine for Filling Bottles with Liquids.
We, GEORGE GALBRAITH, Cabinet Maker, and FRED WALLIS, Pattern
Maker, both of Platt Street, Rochester, Monroe County, New York State, U.S.A.,
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 :-
The machine of this invention is designed for continuously filling bottles and
like articles with liquids, said bottles automatically governing the flow of the
liquid and being readily and quickly engaged in and disengaged from the
machine.
In the accompanying drawing which illustrates the invention
Fig. 1 is a sectional view of the machine, the upper part of a bottle being
shewn connected to one of the discharge tubes.
Fig. 2 an elevation of one of the discharge sockets with discharge tube.
Fig. 3 a vertical section on line 3-3 of Fig. 2, and
Fig. 4 a vertical section on line 4-4 of Fig. 3.
A is a supporting frame shewn as composed of upper and lower sections a, a',

page_text: to
B a container for the liquid to be filled into bottles. It is shewn cylindrical and
with the bottom sloping downwards from the centre to the circumference and is
preferably adapted to be rotated. C a vertical shaft carried in upper and lower
bearings a³, a and having the container fixed on its upper end. The shaft is
driven from bevel gearing C¹, D', the latter fixed on a shaft D carried at one
end in a bearing as and the other end, not shewn, connected in
any suitable way
power mechanism. E a series of discharge sockets or spouts arranged in a circle
and fixed in the bottom 6 of the container. Each of these parts is formed with a
guide way El and a recess E² open to the container and communicating with the
guide way E¹. F a series of discharge tubes each supported in a socket E and
movable in the guideway E' therein. Each discharge tube F has a closed top f
and one or more inlet openings fl in its circumference, and its lower end is
inclined outwardly and provided with an outlet f' closeable by a valve G carried
on the end of a stem g passing through the tube and secured to a cross bar e at the
top of the recess E'.
The discharge tubes F are provided with shoulders F guided in the chamber E
so that when the upper ends of bottles or the like to be filled are inserted in
said chambers the shoulders F' are engaged, and by the upward movement of the
bottles to be filled the discharge tubes Fare forced from their normal positions,
for connecting the opening f¹ in their upper ends with the corresponding outlet
recesses or chambers E³ and elevating their lower ends above the valves G for
permitting egress of the liquid from the outlets f2.
When the bottles are full they are withdrawn from the chambers E' and the
discharge tubes F assume their normal positions and effectually shut off the
discharge of the liquid. This movement of the tubes F is facilitated by
springs F having their lower ends hearing against the shoulders F¹ and their
upper ends against shoulders e' of the sockets or spouts E.
When a bottle is to be filled the lower end of the discharge tube is inserted in
the same (Fig. 3) and as the bottle is withdrawn the spring F2 moves the tube F
and engages the outlet 2 with the valve G before the bottle is withdrawn from
the tube and the flow of the liquid is thus cut off. In placing the bottle to be
filled the discharge tube F is forced against the resistance of the spring F³ so as
to move the outlet 2 above the valve G. It is evident however that the elevation
of said outlet above the valve only takes place after the discharge tube is within
the bottle and consequently none of the liquid can come upon the outer surface of
the bottle.
Instead of the shoulders being directly engaged by the bottle and the springs
for forcing the tubes to their normal positions, it is preferable in practice and as
shewn in Fig. 3 to provide said shoulders with yielding faces or washers F³ which
reduces to a minimum the noise incidental to the engagement and removal of the
bottles or the like.
The
The inclination of the lower ends of the discharge tubes serves to conduct the
liquid directly against the side of the bottle so that it flows uniformly, without
the formation of bubbles and so that the air may more readily escape.
escape of air is also facilitated by vent or drip tubes H having their inner ends
opening from the lower faces of the shoulders F and their lower yielding
faces F, and the central portions guided through apertures in the sockets E and
having down turned ends. These ends discharge any liquid conducted therein
into a receptacle I provided with upwardly extending arms i detachably engaged
with a ring or other suitable support B' having arms B2 attached to the bottom of
container B.
Instead of providing the sockets E with outlet recesses E2 into which the
discharge tubes project, said recesses may be omitted and the tubes project into
the container B, but this is not to be preferred as it is desirable not to have
anything projecting above the bottom of the container.
J are clamps for holding in position the bottles to be filled, and as preferably
constructed, these clamps consist of levers pivotted at ; to the sockets E and

page_text: provided at their lower ends with shoulders or engaging ends; for engaging
shoulders 2 upon the upper end of the bottles 1 to be filled. The upper ends of
the clamps or levers J are provided with apertures ; guided longitudinally along
arms projecting from the sockets E. These arms are encircled by spiral
springs J having their inner ends bearing against adjustable shoulders e upon the
inner ends of said arms, and their outer ends bearing against the upper ends of
the clamps J for forcing the lower ends of the same to the operative position.
e are adjustable shoulders at the outer ends of arms et and in conjunction with the
adjustable shoulders e serve to govern the movement of the clamps J and adjust
the tension of the springs J'.
When a bottle after being filled is withdrawn downwardly the lower ends of the
clamps J are forced outwards by the shoulder 2.
In operation the time of a portion of a revolution of the container B is equal'
to the time required for filling a bottle by a discharge tube F and consequently
an operator stands at one part of the machine feeding unfilled bottles thereto and
another operator stands at another part removing the filled bottles.
The details of construction of the machine and the arrangement of the parts
may be readily varied and we do not specifically limit ourselves thereto.
