Improvement in Valves for Taps of Syphons and other Apparatuses
for Aerated Water or Liquids.
We PAUL MITTON, Manufacturer and Merchant 25 Coleman Street E.C.
London, 269 Rue St. Honoré Paris, and 140 Rue Bourbon Châtellerault France,
and PAUL BOBET Manufacturer, Rue des Lions St. Paul, Paris, 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 consists in the application of an improved valve to the taps or
mounts of syphons or any other apparatus intended to contain aerated waters or
other liquids under pressure, and in a special disposition of these taps or mounts to
receive the improved valve and facilitate its working under the pressure exerted
upon the lever which is the ordinary one used for taps of syphons or other
apparatuses.
Until now perfect closure of the valves contained in syphon taps was attempted
by means of a seat composed of elastic material viz. india rubber leather &c.
either fixed to the metal part of the valve, or to the syphon or syphon tap. In
each case the parts of the valve which bad to rest on the seat were parallel or
nearly so to that seat, so that the grit, dirt, or other matters, which got lodged in
the spout of the tap often settled upon that seat, and imbedded itself in the soft
substance under the pressure of the valve acted upon by a strong spring lodged in the
top part of the tap. This preventing the valve from resting properly upon its seat
allowed the gas and liquid to escape.
To prevent the aforementioned drawbacks we have invented a seat quite indepen-
dent of the valve and the tap of the syphon, that is to say not a fixture, but only
lodged in a cavity of a special shape made in the inside of the syphon tap, and
maintained in its position by the tube used for the outflow of the liquid. A hole of
a conical shape is made in the centre of this seat and in it fits the valve also of a
conical shape thus obtaining a hermetical closure and preventing the grit &c. from
settling upon the seat for by means of the inclination given to the surface of the
valve and seat we facilitate the passage of any undesirable matter which might
come in contact with the seat.
Assuming it is desired to apply it to au ordinary syphon for mineral waters,
Fig. 1 shows the tap of an ordinary syphon fitted with the improved valve held
closed upon its seat by the ordinary spring contained in the taps.
Fig. 2 shows the same tap fitted with the improved valve arrangement, the valve
itself being held open by a pressure upon the outside lever nullifying the action of
the spring.
Fig. 3 shows the plan aud section of the seat of the valve, this seat can be made
of india rubber leather, gutta percha, cork, compressed paper or any other elastic
material.
Fig. 4 shows an horizontal and sectional plan of valve of which the part fitting
in the seat has the shape of a cone with the upper part cut off.
To the syphon tap, constructed as usual as regards the spout B. for the outflow
and the lever C, is fitted in the inside chamber D, which screws on or fits in any
convenient manner upon the aperture of the recipient for aerated water, the improved
valve (Fig. 4) which fits in its seat of a special shape (Fig. 3).
In the chamber D is a hollowed part E having the size of the ring or washer F.
forming the seat of the valve; to this is, if desired, added another hollowed part G.
this to lessen the weight of the tap. The seat F rests upon the metal parts E. & H.

page_text: and is kept in its position by the pressure exerted upon it by the tube K used for
the outflow of the liquid.
The seat has in its centre a hole of a conical shape or it may be almost cylindrical
whose largest opening is in the chamber D the conical surface of the hole is the
seat of the valve.
The valve S is formed by a conical or it may be almost cylindrical part of the
same diameter as the conical hole made in the seat, but of a thickness slightly greater
than that of the seat F. Under this conical part F can be added a ridge S¹ and to
the valve is added a cylindrical part L bearing two wings U which enable the
screwing of the valve S in its place, by means of the threaded bole V on the
threaded spindle I which is acted upon by the lever C.
The position of the valve S is regulated on the spindle I so that it presses upon
the seat F.
The lever C. being pressed upon the spindle I is pressed down and the valve S.
is held apart from the conical hole at the seat F which is kept in its place by the
tube &c.
When the syphon is being filled up the undesirable matters which might have
been introduced in the spout B passing through the part H slide on the conical
surface of the hole of the scat F and cannot stop on that surface.
This seat and this valve can be made of any suitable materials and can be secured
in their respective position by any other suitable means than the one above
described as an example. The conical part may in some cases be made almost
cylindrical.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
1st. In syphons and other apparatuses, intended to contain aerated water and
liquids, the application of an improved valve arrangement consisting of a seat
(round piece or washer) of any suitable material, having in the centre a conical, or
it may be almost cylindrical hole, according to the requirement, into which fits a
valve of a corresponding shape conical or almost cylindrical and corresponding in
diameter, surmounted by a cylindrical or prismatical part enabling it to be screwed
upon the spindle as above described.
2nd. The fitting up of the improved valve and seat to the taps of syphons or
other apparatuses intended to contain aerated liquids.
3rd. Securing same to the taps and recepients in the way above described or in
any other way as may be most suitable to the shape of the recipients.
