I, JOHN HAYTHORN, of Mansewood, Pollokshaws, in the County of Renfrew, North
Britain, Engineer, do hereby declare the nature of this invention to be as follows,
that is to say:
My said invention has for its object to improve the construction of valved
mouthpieces for siphons, bottles, or vessels for containing aerated or effervescent
liquids.
A mouthpiece made with my improvements is fitted to be fixed in the ordinary
way upon the neck of a siphon, bottle, or other vessel; and it is made with an
internal shoulder which retains in position a disk tightly applied to the vessel mouth
with an interposed rubber ring. The disk is formed with a central valve port, to
which is applied an internal valve of rubber, gutta percha, or other suitable inaterial
or combination of materials, fixed on a small spindle or wire, which extends outwards
through the valve port. The outer end of the valve spindle is fixed in a central piece
of vulcanite or other suitable material, which is either formed in the same piece with
or is fixed in a piston piece which fits and moves in an internal cylindrical part of the
outer shell of the mouth piece. The piston piece is made with a nozzle projecting
axially through an opening in the outer end of the mouthpiece; and holes or passages
formed through the central piece form communications between the nozzle and the

projecting central part having on it in the annular space between it and the piston
piece a short rubber tube, the inner end of which bears on the valve-port disk,, and
which either itself acts as a spring or has a helical spring applied to it to insure the
closing of the valve when it is not being pressed inwards. The valve is opened by
moving the piston piece inwards, this being done, when filling the vessel, by entering
the nozzle into the delivery nozzle of the filling apparatus. On withdrawing the
nozzle the valve instantly closes and prevents escape of gas. For opening the valve
for the purpose of delivering the contents or a portion of them into a glass or other
vessel, a small lever to be moved by the finger or thumb is fitted to the mouthpiece,
and is arranged to act on the piston piece in any convenient way.
The mouthpiece may be made of metal and any internal parts of it with which the
liquid might come in contact may be lined or coated; or the entire mouthpiece may
be made of vulcanite or other suitable material.

page_text: Improvements in Valved Mouthpieces for Siphons, Bottles, or
Vessels for containing Aerated or Effervescent Liquids.
I, JOHN HAYTHORN, of Mansewood, Pollokshaws, in the County of Renfrew, North
Britain, 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:-that is to say :-
My said invention has for its object to improve the construction of valved
mouthpieces for siphons, bottles, or vessels for containing aerated or effervescent
liquids.
And in order that my said invention and the manner of performing the same
may be properly understood. I hereunto append two sheets of explanatory drawings
to be hereinafter referred to and showing three modifications of my improved
valved mouthpieces.
Figure, 1, on Sheet, 1, of the drawings is a horizontal section, Figure, 2, an
elevation at right angles to Figure, 3, which is a vertical section, and Figure, 4,
is a horizontal section all of one modification. Figure, 5, on Sheet, 2, is a
horizontal section, and Figure, 6, vertical section of a second modification.
Figure, 7, is a horizontal section; and Figures, 8, and 9, are vertical sections as at
right handles to each other of a third modification. In these drawings the same
reference letters are used to mark the same or like parts wherever they are
repeated..
A mouthpiece, A, made with my improvements is fitted to be fixed in the ordinary
way upon the neck of a siphon, bottle, or other vessel, B, and it is made with
an internal shoulder which retains in position a disk, C, tightly applied to the
vessel mouth with an interposed rubber ring, D. The disk is formed' with a
central valve port, E, to which is applied an internal valve, F, of rubber, gutta
percha, or other suitable material or combination of materials, fixed on a small
spindle or wire, G, which extends outwards through the valve port. The outer end
of the valve spindle, G, is fixed in a central piece, H, of vulcanite or other suitable
inaterial, which is as shown in Figures, 5, to 9, formed in the same piece with a
piston piece, J, or as shown in Figures, 1, to 4, this central piece, H, is fixed in the
piston piece, J. The piston piece, J, fits and moves in an internal cylindrical part
of the outer shell of the mouth piece; A. The piston piece, J, is made with a nozzle,
K, projecting axially through an opening in the outer end of the mouthpiece, A,
and boles or passages, L, formed through the central piece, H, form communications
between the nozzle, K, and the space between the central piece, H, and the valve-
port disk, C.
A movable cap may be adapted to the end of the nozzle. The
central piece, H, is formed' with an inwardly projecting central part having on it a
short rubber tube, M, the inner end of which bears on the valve-port disk, C, and
which either itself acts as a spring or as shown in Figure, 3, has a helical spring, N,
applied to or embedded in it to insure the closing of the valve, F, when it is not
being pressed inwards. The valve, F, is opened by moving the piston piece, J,
inwards, this being done, when filling the vessel, by entering the nozzle, K, into the
delivery nozzle of the filling apparatus, (not shown). On withdrawing the nozzle, K,
the valve instantly closes and prevents escape of gas. For opening the valve, F, for
the purpose of delivering the contents or a portion of them into a glass or other
vessel, a small lever, P, is as shown in the modification described in Figures, 1, to 4,
fitted to a part of a ring, Q, which projects through a slot in the upper part of the
mouthpiece, A, in which part the ring is held. This ring, Q, is formed with a

page_text: number of inclined surfaces or teeth, R, which gear with corresponding surfaces, S,
on the piston piece, J, and on the lever, P, being raised into the position shown in
dotted lines in Figure, 3, and turned with the ring, Q, as far as the slot will allow
the action of the inclined surfaces, R, and S, will depress the piston piece, J,
and open the valve, F, which will be closed again by the spring, N, on turning
back the ring, Q.
In the modification shown in Figures 5, and 6, the lever, P, is made with a forked
inner end which works in slots in the mouthpiece and bears directly on the piston
piece, J, the outer end of the lever being turned down so that when it and the bottle
mouthpiece are grapsed by the hand and pressure applied the lever will be pressed
into the position shown by dotted lines in Figure, 6, and the valve, F, opened.
In the modification shown in Figures, 7, to 9, the inner end of the lever, P,
instead of being forked is made in a single piece.
The mouthpiece, A, may be made of metal and any interual parts of it with which
the liquid might come in contact may be lined or coated; or the entire mouthpiece'
may be made of vulcanite or other suitable material.
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-
A valved mouthpiece for siphons, bottles, or vessels for containing aerated or
effervescent liquids, having in combination a disc formed with a valve port to which
is applied a valve on a spindle fixed in a central piece of a piston made with a nozzle
projecting through the end of the mouthpiece, the central piece having holes or
passages formed in it and having on it a short rubber tube with or without a helical
spring; and means for opening the valve substantially as herein before described with
reference to any of the modifications shown on the accompanying drawings.
