Improvements in the Heads of Siphons for Aerated Liquids.
We, THOMAS HOWELL WILLIAMS IDRIS, of 110, Pratt Street, Camden Town,
in the County of London, Mineral Water Manufacturer, RICHARD HOOSON
GRIFFITH, of 8, South Villas, Camden Square, Camden Town aforesaid Manager
of Syphon Factory, and IDRIS & Co., LIMITED, whose registered office is
situate at 120, Pratt Street, Camden Town aforesaid, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
The objects of this invention are to simplify the construction of siphon
heads and to prevent the liquid from coming into contact with metal.
The outer casing of the head consists of a tube preferably made of nickel plated
steel or other hard metal which is secured to the body of the siphon by screwing
it on to a split ring in the usual way. The tube descending into the siphon
carries on its top a washer of indiarubber or like material which rests on the
top of the siphon bottle. Above this washer and fitting inside the tube is a block
of earthenware or the like. This block carries the nozzle which projects through
a slot made in the side of the tube. The block is perforated axially for the
passage of the liquid and has a groove in its top communicating with the
hole through the nozzle-above the block is a second washer forming the valve
and above this is a ring also fitting inside the tube but projecting above it.
Inside the ring is a plunger resting on the valve washer and above it is a spring.
A cap screws on to the top of the tube and pressing on the spring holds the
parts in place. The lever for actuating the valve passes through a slot in the
cap and rests on the edge of the ring as a fulcrum its nose engaging with a slot
in the plunger.
In place of having a lever for operating the valves of these and other siphons
a rotating cap may be employed. This cap turns on a screw working in a fixed
nut and having its end resting on the valve washer. Inside the cap are one or
more springs tending to bring it back again when released.

GRIFFITHI, of 8, South Villas, Camden Square, Camden Town, aforesaid Manager

declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:—
The objects of this invention are to simplify the construction of siphon heads
and to prevent, the liquid from coming into contact with metal.
Figure 1 is a side elevation and Figure 2 a vertical section of a siphon con-
structed according to this invention. Figure 3 is a plan of the block f.

The
The outer casing of the head consists of a tube a preferably made of nickel
plated steel or other hard metal which is secured to the body of the siphon
by screwing it on to a split ring c in the usual way. The tube d descending into
the siphon body has a flanged top. Around the top of tube but below the
flange is an annular washer e of india rubber or like material which rests on the
top of the siphon body. Above this washer and fitting inside the tube a is a
block of earthenware or the like. This block has made in one piece with it the
nozzle which projects through a slot made in the side of the tube a.
block is perforated axially at h for the passage of the liquid and has a groovej in
its top communicating with the hole through the nozzle g. Above the block
is a disc washer forming the valve and above this is a ring 7 also fitting inside
the tube a but projecting above it. Inside the ring is a plunger m resting
on the valve washer and above the plunger m is a spring . A cap o screws
on to the top of the tube a and pressing on the ring 7 and the spring n holds
the parts in place. The lever p for actuating the valve passes through a slot in
the cap and rests on the edge of the ring as a fulcrum its nose engaging with
a slot in the plunger m.
In place of having a lever for operating the valves of these and other siphons
a rotating cap may be employed as shown in Figures 4 to 6. This cap 7 turns
a screw working in a fixed nut in the cap a and having its end resting on the
valve washer k.
Inside the cap g are springs s tending to bring it back again when released.
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 :-
:-
1. The combination of a siphon body, an inner tube of glass or like material,
a block of earthenware or like material having perforations in it leading from
its upper face to the inner tube and to the spout, an annular washer between the
block and the body, a disc washer on the upper face of the block, a ring above
the disc washer, an outer tube surrounding the block and connected to the
body, a cap screwing on to the outer tube and pressing on the ring and means
for pressing the middle of the disc washer against the upper face of the block.

page_text: 2. Actuating the valve of a siphon by a lever bearing on the edge of a ring
which forms its fulcrum.
3. Actuating the valve of a siphon by a screw working in a fixed nut and.
turned by a revolving head provided with a spring or springs to return it after
being turned.
4. Siphons substantially as described and illustrated in the drawings.
