COMPLETE SPECIFICATION.
Improvements in Siphon Heads,
I, CHARLES LOUIS HUSTED, residing at 205, Monitor Street, in the City of New
York, in the County of New York, and State of New York, United States of
America, Salesman, 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 relates to siphons, and particularly to the heads thereof, and
the object of the invention is to provide an improved siphon head for siphon
bottles or other vessels which is so constructed that in the event of an excess of
pressure of gas within the bottle or vessel which would ordinarily result in the
explosion thereof, said extra pressure may be discharged so as to prevent such
explosion; a further object being to so construct the siphon head that it will be
effective in operation, and also durable and economical in construction;
with these and other objects in view, the invention consists in the construction,
combination, and arrangement of parts hereinafter described and claimed.
and
The invention is fully disclosed in the following specification of which the
accompanying drawing forms a part, in which; -
Fig. 1, is a central vertical section of the upper part of a siphon bottle or other
vessel and the neck thereof provided with my improvement; and,
Fig. 2, a side view of a detail of the construction.
In the drawing forming part of this specification, the separate parts of my
improvement are designated by the same letters of reference in each of the views,
and in the practice of my invention, I provide a bottle or other vessel A, having
a neck a, the upper end of which is screw threaded as shown at a², and below
the screw threaded portion thereof is preferably formed an annular shoulder or
projection a³.
I also provide a tubular siphon head B, the lower end of which is enlarged and
interiorly screw threaded as shown at b, so that it can be connected with the
screw threaded portion of the neck a, and the upper end of the tubular head B
is closed by a cap C, having a screw threaded portion C³, which is screwed into
the head B..
Placed upon the screw threaded end of the neck a is a plate D which is held
in place by the tubular siphon head B, and the plate D is provided with a central
downwardly directed tubular extension d, in which is secured a supplemental
tube which in practice, extends downwardly approximately to the bottom of
the bottle or vessel A, in the usual manner.

The central bore of the tube d extends through the plate D, and said

above said plate D, and also above the tubular extension d³, is a spring
depressed hollow plunger G, which is open at one side as shown at g, and to the
lower side thereof is secured a valve of soft rubber or similar material which
is adapted to close the upper end of the tubular extension d², as shown in Fig. 1.
The valve g is slightly conical in form, and the smaller end thereof is directed
downwardly, and the base or upper end is large enough to snugly fit the inner
walls of the tubular siphon head B, as shown at g³, and said tubular siphon head

page_text: is provided on one side with a slot or opening H, and mounted therein is a lever h
having a head h2 which projects into the plunger G, and which is adapted to
bear on both the lower and upper wall of said plunger, and particularly on the
upper wall thereof.
The tubular siphon head B is preferably composed of lead, block tin or other
soft metal, and in practice I pass through the side thereof in the bottom of the
slot or opening H a hard metal rod h³, which serves as a fulcrum or bearing for
said lever, and the head h² of said lever is provided with a shoulder * which
operates on the inner side of said rod, which together with the upper side of the
plunger prevents the withdrawal of the lever when the parts are in their normal
position.
I also place in the upper portion of the hollow plunger G, which is preferably
composed of block tin or other soft metal, a hard metal plate on which the head
of the lever bears, in the operation of said lever, and the said plunger is normally
depressed by a strong spiral spring K, which is mounted in the tubular head B,
one end of which bears on said plunger, and the other on the cap C.
The discharge spout L communicates with the tubular head below said plunger,
when said plunger is in its lowest position as shown in Fig. 1, and the lower end
of the valve g², is made small enough to permit the contents of the bottle or other
vessel A to freely flow around it and to escape through the discharge spout L.
The upper end of the plunger G is preferably provided with a groove gas
shown in Fig. 2, in which a packing ring may be placed if desired, and said
plunger is also provided with an upwardly directed pin or projection which
passes into the lower end of the spring K, and a correspondingly downwardly
directed pin or projection C3 is formed in the cap C, which enters the upper end
of said spring, but these pins or projections and C, although intended for
keeping the spring in place, are not essential and may or may not be employed.
It is not necessary to remove the siphon head B when repairs are necessary, all
that is requisite in this case being to remove the cap C, and by means of this
coustraction, the breaking of the neck of the bottle or the destruction of the siphon
head B is prevented, and the valve g² may be renewed whenever desired, and said
valve may be made of any desired material.
The upper portion of the valve g² is made large so as to closely fit the inner
walls of the tubular siphon B in order to prevent the contents of the bottle or
vessel from passing upwardly through said head, and escaping at the side of the
plunger through the slot or opening H, in the side of said tubular head.
The operation is the same as in all other devices of this class. In order to dis-
charge the contents of the bottle or vessel, all that is necessary is to press the
outer end of the lever hand when the pressure is removed from the outer end of
said lever, the spring K at once forces the valve upon its seat, and the port
or passage through the tubular extension is closed. If however the pressure
of gas in the bottle becomes very great, it will overcome the action of the spring K
and escape through the valve, thus there is no danger of the bottle being broken
from this cause.
The side of the tubular siphon head B is enlarged as shown at M, to form bear-
ings for the rod h³, and my improvement is simple in construction and operation,
and is well adapted to accomplish the result for which it is intended, while being
also comparatively inexpensive.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is―
1. In a siphon head, a spring controlled valve located over and operating
normally to close the outlet of the siphon tube, said valve being connected with
a hollow plunger fitted to slide in the upper portion of the siphon head and pro-
vided with a slot or opening, in one side thereof, and a removable lever for raising

page_text: said valve from its seat, said lever extending through a slot or opening in the
siphon head, and having a head adapted to pass loosely through the opening in
the plunger, the lever being provided with a fulcrum, and the head thereof with
a shoulder, which together with the plunger prevents the withdrawal of the lever
in the normal position of the parts, substantially as shown and described.
2. A siphon bottle or other vessel provided with a neck, and a tubular siphon
head secured thereto said head being provided with a plate which rests on the
neck, and is held in place by said head, and said plate being provided with a tube
which passes therethrough and projects slightly above the same, a vertically
movable spring depressed plunger mounted in said tubular head above said plate
and provided at its lower side with a valve which is adapted to close said tube,
and the upper portion of which closely fits the inner wall of said tubular head,
said plunger being also provided in one side thereof with a slot or opening, and
the tubular head with a corresponding slot or opening, and a lever mounted in
the slot or opening of the tubular head and provided with a head which projects
into the plunger, said tubular head being also provided with a detachable cap
between which and the plunger the spring by which the plunger is depressed is
placed, and said tubular siphon head being also provided with a discharge spout,
substantially as shown and described.
