An Improved Bottling Cock for Liquids.
I, GEORGE MITCHELL of 47 Victoria Street, Westminster, in the County of
London, Consulting Engineer, do hereby declaro the nature of this invention to bo
as follows:-
This invention relates to cocks suitable for drawing off liquids into bottles or other
vessels in which a vacuum is created, and is especially suitable for use in bottling
oil, or other liquids, which by reason of their viscosity, are with difficulty caused to
flow into such bottles.
It consists of a cock the casing of which has five passages formed in it, the first
of which communicates with the atmosphere through a rose filter to ensure the
admission of pure an, the second with a vacuum pump or vessel, the third with the
oil or other liquid container or receiver, the fourth to convey the oil into the bottle,
and the fifth (which is common to the first and second) terminates round the fourth
by means of a sleeve formed by placing one tube inside the other.
The nozzle or lower end has a conical cap (covered preferably with rubber) and
though which, at its centre, passes the tubes or passages indicated as the fourth
and fifth aforesaid.
Fitting in this casing is a plug or its equivalent, the passages in which are so
formed, that one movement of the handle produces the following results
-
1st. (a) The communication between the atmosphere and the bottle is closed.
(6) The vacuum vessel is put in direct communication with the bottle, and
thereby produces a vacuum inside it.
(c) The communication between the oil or liquid receiver or container and
the bottle is opened and by reason of the vacuum which has been created,
the bottle is filled as required.
2nd. By retuning the handle to its original position.
(a) The communication between the vacuum vessel and the bottle is
closed.
(*) The communication between the liquid receiver and the bottle 13
closed.
(c) The communication between the atmosphere and the bottle is opened
and thereby the vacuum destroyed.
While the bottle is filling it is suspended to the nozzle, by means of the
atmospheric pressure; there being a vacuum uside the bottle and the comical cap
referred to forming an air-tight joint for any ordinary sized neck of bottle.
When
the bottle is filled with liquid there is no vacuum inside it, and the atmospheric
pressure ceasing to support the bottle, it drops off on to a platform placed underneath
to receive it.
In filling, if the bottle is cracked or defective it is so indicated by the inrush of
the atmospheric aii.
The fourth tubo hereinbefore referied to, is carried down into the bottle so far
that its displacement in the oil or other liquid will allow room for the cork, whon
the buttle has dropped off the machine.

I, GEORGE MITCHELL of 47 Victoria Street, Westminster, in the County of
London, Consulting Engineer, do hereby declare the nature of this invention and
u what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention relates to cocks suitable for drawing off liquids into bottles or
other vessels in which a vacuum is created; and 18 especially suitable for use m
bottling oil or other liquids which, by reason of their viscosity, are with difficulty
caused to flow into such bottles.
It consists of a cock, the casing of which has five passages formed in it, the first
of which communicates with the atmosphere through a rose filter to ousure the
admission of pure air, the second with a vacuum pump or vessel, the thud with the
oil or other liquid container or receiver, the fourth to convey the oil into the bottle,
and the fifth (which is common to the first and second) terminates round the fourth
by means of a sleeve formed by placing one tube inside the other.
The nozzle or lower end has a conical cap (covered preferably with rubber) and
though which, at its centre, passes the tubes or passages indicated as the fourth and
fifth aforesaid.
Fitting in this casing is a plug or its equivalent, the passages in which are so
formed that one movement of the handle produces the following results.
1st. (a) The communication between the atmosphere and the bottle is closed.
(6) The vacuum vessel is put in direct communication with the bottle and
thereby produces a vacuum inside it.
(c) The communication between the oil or liquid receiver or container and
the bottle is opened and by reason of the vacuum which has been created
the bottle is filled as required.
2nd. By returning the handle to its original position
(a) The communication between the vacuum vessel and the bottle iч
closed.
(6) The communication between the liquid receiver and the bottle is
closed.
(c) The communication between the atmosphere and the bottle is opened
and thereby the vacuum destroyed.
While the bottle is filling it is suspended to the nozzle by means of the atmospheric
pressure; there being a vacuum inside the bottle and the conical cap referied to
forming an air-tight joint for any ordinary sized neck of bottle. When the bottle
is filled with liquid there is no vacuum inside it and the atmospheric pressure ceasing
to support the bottle it drops off on to a platform placed underneath to receive it.
In filling if the bottle is cracked or defective it is so indicated by the inrush of
the air.
The fourth tube herein before referred to 18 carried down into the bottle
so far that its displacement in the oil or other liquid will allow 100m for the
cork when the bottle has dropped off the machine.
In the accompanying diawings:-
Fig. 1 is a veitical section of a bottling cock according to my invention.
Fig. 2 is a front elevation (part section) and
Fig. 3 is a plan of same.
Fig. 4 18 a section of the plug.
Fig. 5 is a section on line 1, 1, and
Fig. 6 is a section on line 2, 2, of Fig. 4
Fig. 7 is a view of the rose filter face.
A designates the body of the cock having a nozzle a by which it is screwed

page_text: communicates through a passage a¹. This passage is drilled through the whole
length of the body of the cock, and is continued at its lower end by a filling tube a
which projects a sufficient distance to enter the bottle, and its displacement in
oil is such that when the bottle drops off the nozzle after filling, room 18 left
for the cork The cock body at its lower eud a is screwed on its outside and
a cap a fits over it the interior of which (with the end a³) forms an annular
chamber a. Into the underside of the cap a 18 screwed a sleeve a' the interior
diameter of which is larger than the outside diameter of the tube a² which it
surrounds and an annular space a* 18 thereby left between the two which thus
communicates above with the chamber a and below opens into the mouth of
the bottle. To the underside of the cap a is rigidly attached a soft and elastic
cushion a' which surrounds the sleeve a and secures an air-tight joint with the neck
of the bottle.
The body of the cock is bored comically to form an air-tight seating for the plug B
which is secured in position by any convenient means preferably by a cap a
and to the stem 6 of the plug is attached a handle b by means of which the
plug can be turned and caused to make one part of a revolution. On one side
of the body of the cock A is an extension a° inside of which a passago al is
drilled in a line with the axis of the plug B and the passage 18 in one position of
the plng connected by a passage a" with the annular chamber a' and also with the
interior of a pump of vessel in which a vacuum is maintained. To any couvenient
point at one side of the body of the cock A is attached a rose filter Ć the face of
which is dulled with a large number of small holes and the interior c of which is
filled with any filtering medium suitable for securing the purity of the air passing
into the cook through the rose filter and passage c'.
The plug B has drilled transversely through it a passage b' by means of which
with the passage a' and the filling tube a' the oil container or receiver can be placed
in direct communication with the inside of the bottle; the whole of these threo
passages a, b, and a' forming in one position of the plug a straight line for the flow
of the oil from the container to the bottle Near the end of the plug and half way
through it is drilled (parallel to ) a passage and at right angles to this in the
axial line of the plug is a continuation &ª of the passage b'. When the plug B 18
turned so as to bring in a line with a" a cominunication is thus established
between the vacuum vessel and passage ao and the annular spaces a' aud a*. A
quadrantal groove 6ª formed in the surface of the plug enables a communication to
be established between the air passage d' and the passage a".
In the position of the handle shewn u the drawings the vacuum vessel is in
communication with the interior of the bottle through a, b, b, a", a³ and a*; and
the oil from the container is free to flow into the bottle though a', ', a', and filling
tube a³.
The shape and position of the different passages may be slightly modified, and
arianged in such manner that it will be necessary to turn the handle through half
or any part of a revolution, but in the drawings the passages are so arranged
suitable for a movement of the handle and plug of not less than one forth of a
revolution.
The operation is as follows:-
The handle being supposed to be turned upwards from the position shewn in the
drawing to the right band one fourth of a revolution so as to assume a horizontal
position, the communication between both the vacuum vessel and the oil container
is thereby shut off and the annular space a 18 opened to the passage c¹ and rose
filter C. A battle X being applied to the filling tube a' as shewn in Fig. 1 the
handle is turned downwards to the position shewn, the communication between the
rose filter and the bottle is closed and as soon as the end of the passage b* opens to
the passage a¹ the communication between the vacuum vessel and the bottle 18
established, and the air in the latter passes out through the annular space a*, the
aunular chamber a', the passages a, b, b, and a into the vacuum vessel. A
vacuum is thus created in the bottle which holds it firmly up to the clastic cushion a'

page_text: thus securing an air-tight joint. The same movement of the handle establishes
diect communication between the bottle and the oil container, and the oil continues
to flow down through the passages a', 6, a' and filling tube a' until the bottle is
filled. As soon as the bottle is filled it drops off on to a platform by reason of the
vacuum inside it being destroyed, and the handle being at once turned back to the
original horizontal position the end of the passage is closed to the passage all, and
simultaneously the passage is closed to a' thus interrupting communication between
the bottle and both the vacuum vessel and oil container. As soon as the handle
reaches the horizontal position the grooved passage establishes a communication
between c¹ and all and thei oby admits the atmosphere to the annular chamber a
and to the mouth of the botile in case the latter has not dropped off.
Having now particularly described and ascertained the nature of my aaid
invention and in what manner the same is to be performed I declare that what I
claim is.
1. A bottling cock for liquids which by one movement of a plug or equivalent
device closes all communication between the bottle and the atmosphere, opens the
bottle to a vacuum vessel and to an oil container and receiver, and by the return
movement closes communication between the bottle and both vacuum vossel and oil
Container and opens the communication with the atmosphere, substantially as shown
and described.
2. A bottling cock for liquids consisting essentially of a casing containing five
passages, the first of which cominumicates with the atmosphere through a rose filter,
the second with a vacuum vessel, the third with the liquid container, the fourth
with the bottle, and a fifth which communicates with the bottle and also with
a vacuum vessel through the second passage substantially as shown and described.
3. In a cock for bottling liquids, the combination of a body A containing
passages a, a, a, a, c' and annular spaces a³ and a*, with a plug B containing
passages,,, and, and an elastic cushion a' which forms an air-tight joint
between the cock and the bottle, substantially as shewn and descubed.
4. Ju a cock for bottling liquids the combination of the cock body A, the plug B,
the rose filter C, the filling tube a³, the sleeve a, and the elastic cushion a
substantially as shewn and described.
