Counters.

I, WILLIAM HOLME DAVIS, of 34 St. Paul's Road, Thornton Heath, Surrey,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention has for object;-—
1. A novel construction or arrangement of aërated liquid fountain to be used on
counters or bars of public houses, restaurants, and other places where aërated liquids
are sold..
2. A special valve within the counter socket.
3. A special nozzle.
4. The use or employment of a pear, or equivalent shaped bulb at the outlet,
whereby the acrating gas is kept in contact with the outflowing liquid, and is
consequently held in the liquid for a long period after it is drawn into a drinking
glass, instead of escaping and the liquid turning flat and lifeless as by the present
systems.
To carry my invention into practice, I form a socket plate for attachment to a
counter, said socket having a pipe with union or other joint for connection with a
main supply or reservoir. The socket is provided with a barrel which may contain
a glass cylinder suitably packed at top and bottom and held in place by screw cap
or otherwise, the cap supporting a head, within which a turning plug is fitted con-
trollable by a handle. This plug has a passage through it to the outlet nose, the
end of which is. closed and has radial holes slanting upwards for directing the
issuing liquid against the upper wall of a hollow pear shaped bulb, covering same,
the lower narrow end of the bulb serving as a nozzle for the outflow of liquid into
a drinking glass.
The turnable plug is in a piece with a tube. rod projecting downwards into the
socket and its lower end, provided with a diagonal passage, has a seating on a plate,
which is kept in contact by a spring, this scating has a hole near the edge,
over which the diagonal hole in lower piece can be made to coincide when the
handle is turned for drawing off purposes. The tubular portion of the rod stops
just above the inner bottom of the barrel and has a passage therefrom to the tube
for the liquid to pass up to the plug in the head, this being forced up by,
the internal pressure above the liquid in the barrel as with the well known
siphon.
To prevent the sudden rush of liquid from the reservoir into the barrel, I affix
to the bottom portion of the tube rod, a deflected or cone plate from under which
the liquid passes into the barrel.
I form an annular groove in the plug and by a passage in the head, I make
coinmunication with a snift valve fitted for the escape of superfluous pressure.
The pear shaped bulb is applicable to all kinds of outlet nozzles of siphons, and
is a speciality in my invention.

SPECIFICATION.
Improvements connected with Aërated Liquid Fountains for use on
Counters.
I, WILLIAM HOLME DAVIS, of 34 St. Paul's Road, Thornton Heath, in the
County of Surrey, Gentleman, 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 has for object;
1. A novel construction or arrangement of aerated liquid fountains to be used on
bars of public houses, restaurants, and other places where aerated liquids are
sold.
2. A special valve within the counter socket.
3. A special nozzle.
4. The use or employment of a pear or equivalent shaped bulb at the outlet,
whereby the aerating gas is kept in contact with the outflowing liquid for a long
period after it is drawn into a drinking glass, instead of escaping and the liquid
turning flat and lifeless as by the present system.
To carry my invention into practice and as shown in the annexed drawings I
form a socket plate A for attachment to a counter B, said socket having a pipe C
with union or other joint D for connection with a main supply or reservoir.
The socket A is provided with a barrel E which may contain a glass cylinder F
suitably packed at top G and at bottom H and held in place by screw cap I or
otherwise. The cap 1 supports a head J within which a turning plug K is fitted,
controllable by a handle L. This plug K has a passage through it, as in dotted
lines, to the nose M, a branch N on the end of which is closed and has radial
holes N, N, slanting upwards for directing the issuing liquid against the upper
wall of a hollow pear shaped bulb P covering same, the lower narrow end
bulb serving as a nozzle for the outflow of liquid into a drinking glass.
of the
The turnable plug K is in a piece with a tube rod R projecting downwards into
the socket A and its lower end $ provided with a diagonal passage, shown in dotted
lines, has a seating on a plate T which is kept up in contact by a spring U. This
seating has a hole, also in dotted lines in the figure, near the edge over which the
diagonal hole in lower piece S can be made to coincide when the handle L is turned
for drawing off purposes. The tubular portion of the rod stops just above the
inner bottom of the socket A and has a passage V therefrom to the tube for the
liquid to pass up to the plug K in the head J, this being forced up by the internal
pressure above the liquid in the barrel as with the well known syphon.
To prevent the sudden rush of liquid from the reservoir into the barrel, I affix
to the bottom portion of the tube rod a deflected or cone plate W from under
which the liquid passes into the barrel.
>
I form an annular groove X in the plug, and by a passage Y in the head I make
communication with a snift valve fitted for the escape of superfluous. confined air
and permitting the barrel to fill to the required height.
The pear shaped bulb P is applicable to all kinds of outlet nozzles of siphons
and is a speciality. in my invention.
It may be observed that while the. contents of the barrel E, F, are being drawn
off by the outlet Q a fresh supply to the barrel from the reservoir is entering into
the barrel, so that the pressure from within the reservoir serves to add fresh life
to that within the barrel by acting in conjunction with the pressure already in the
barrel.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The arrangement of the several parts constituting a counter syphon for
aerated liquids as hereinbefore described and as shewn in the annexed drawings.
2. In a counter syphon for aerated liquids of the kind shown on the drawings,
the plug P within the socket A and having a diagonal hole upwardly bored for
opening and closing the passage in the seating plate T when turned by the
handle at the upper part of the syphon as described with reference to the
annexed drawings.
3. The employment of a pear or equivalent shaped bulb such as P on the nozzle
end of any aerated liquid syphon, as set forth.
4. In combination with a pear or equivalent shaped bulb on the nozzle end of
any aerated liquid syphon, the closed up end N with side holes slanting upwardly
as and for the purposes described.
