Improvements in Siphon-heads.
We, GERMAIN MORENCY, of West Seventh Street, Cincinnati, State of Ohio,
Salesman, and LOUIS FRITZ, of Robins Avenue, Covington, State of Kentucky,
Bottler, both of the United States of America, do hereby declare the nature
of this invention, and in what manner this same is to be performed, to be
particularly described and ascertained, in and by the following statement:-
This invention consists of certain novel constructions, combinations, and
arrangements of parts, all of which will be hereinafter more particularly set forth
and claimed.
Fig. 3
In the accompanying drawings, forming part of this specification, Figure 1
represents a perspective view of the device embodying our invention applied to a
bottle. Fig. 2 represents a central vertical section through the same.
represents an enlarged detail perspective view of the valve. Fig. 4 represents an
enlarged detail perspective view of the sleeve for holding the rubber washer in
position, and Fig. 5 represents an enlarged detail perspective view of the valve-
operating handle.
1 in the drawings represents the bottle; 2, the cap proper; 3, the vertical
tubular extension of the same; 4, the delivery-spout; 5, the valve; 6, the
packing-ring; 7, the operating-handle; 8, the coil-spring, and 9, the cap for
closing the tubular extension 3.
The bottle 1 is of any usual siphon construction and is screw-threaded, as at 10,
to receive the screw-threaded cap 2. This cap is provided at its upper end with
an outlet port or passage 11, surrounded on its upper side by an annular ridge 12,
upon which the valve is adapted to be seated, as hereinafter more particularly
described. The said cap 2 is provided with a vertical tubular extension 3, formed
internally with an annular shoulder 13, adapted to support the packing-ring 6.
This ring 6 is set into an annular groove 14, formed in the valve 5 some distance
above its lower end. The lower end of said valve 5 is recessed, as at 15, to receive
the elastic packing 16, which is cast therein, so as to protrude below the lower end
of the same and become seated on the annular flange 12 when the valve is in its
depressed position and thus form an air and water tight joint at this point. The
valve 5 is provided with a reduced spindle 17, surrounded by the coil-spring 8, one
end of which bears against the top of the valve and the other against the under
side of the cap 9, when the same is screwed into the upper end of the tubular
extension 3. This spring 8 normally holds said valve seated over the outlet-
aperture 11, but permits of its being raised away from the same to allow the liquid
to escape. This upward movement of the valve 5 is effected by the operating-
handle 7, which is pivotally mounted between spaced apertured lugs 18, mounted
upon each side of a slot 19, cut through the wall of the extension 3. The forwardly-
projecting nose 20 of said operating-handle enters an elongated slot 21, formed in
the valve, and is adapted to engage the upper wall of the same to lift the valve
when the said handle 7 is depressed. In order to hold the annular packing-ring 6
firmly seated upon the shoulder 13, a sleeve 22 is inserted into the extension 3, so
as to bear with its lower end against the under side of said packing-ring and be

page_text: forced down upon the same by the lower edge of the cap 9 when the latter is
secured in position. Said sleeve 22 is provided with a suitable slot 23, whereby
the nose 20 of the handle 7 may have free movement independent of said sleeve.
The discharge-spout 4 is connected to the vertical extension 3 just above the
discharge opening 11, so that when the valve is raised off of the latter the liquid
under pressure will flow through said opening and out of the spout but will be
prevented from passing upward into the tubular extension 3 by the packing-ring 6.
By the peculiar construction of our improved bottle-top the valve 20 is raised and
lowered without lifting the packing 6 off of the annular shoulder 13, the material of
said packing, which is preferably rubber, stretching to permit of this action. The
said packing-ring is firmly seated on the shoulder 13 by the downward pressure
exerted by the said sleeve 22, which latter is not affected by and does not move
with the valve 20.
By our improved construction of device there is no possibility of the contents of
the bottle becoming contaminated by contact with the working parts inclosed
within the tubular extension 3, nor is there any chance of the valve-packing 16
sticking to the annular flange 12 surrounding the outlet opening, as said packing is
firmly embedded in the lower end of the valve. Further, the construction is such that
any part of the device may be repaired without removing the cap 2 from the neck
of the bottle by simply unscrewing the cap 9 and removing the pivot-screw of the
operating-handle 7. Said cap 9 is preferably provided with air-vents 24 to
allow free ventilation of the interior of the tubular extension 3. There is no.
possible chance of the liquid in the bottle 1 escaping otherwise than through the
discharge-spout 4, as all openings into our improved bottle-top are above the
packing-ring 16.
By protecting the working parts of our improved device from the action of the
gases and liquids within the bottle their life is greatly prolonged and the device
remains operative without repairs for a much longer period than would be possible
were said parts subjected to the influences of the contents of the bottle.
. Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is :-
In a siphon-bottle, the combination with a cap proper having a tubular vertical
extension provided with a valve-seat, an annular shoulder located above
said valve-seat, and a spout having an outlet-opening between said valve-seat and
shoulder, of a spring-pressed valve mounted in the tubular extension and having an
end recess, and an annular channel formed therein, a vertical shank upon the upper
end of said valve, a flexible packing mounted in the recess at the lower end of the
valve, a flexible packing-ring mounted in the annular channel of the valve and
adapted to rest upon the shoulder of the hollow extension, a tube mounted in the
hollow extension about the valve and adapted to bear upon the annular flexible
packing, a coil-spring surrounding said shank, a screw-cap mounted in the upper
end of the vertical tubular extensiou and adapted to bear against the upper end of
the spring and the upper end of the tube surrounding the valve to force the tube
down upon the flexible ring, and an operating-handle pivoted in the tubular extension
and engaging the valve for moving the same upward to unseat it, substantially as
described.
