WILLIAM BRUCE Mineral Water Engineer 13 Randle Street Tranmere in the
County of Chester and WM. THORNE Mineral Water Manufacturer Atherton Street
Birkenhead in the County of Chester do hereby declare the nature of this invention to
be as follows:-
-
Our improvement consists in simplifying the construction of Syphon Bottles and
their metal tops as used in the Mineral Water Trade. Those now in general use are
in eleven parts and by making them on our principle we dispense with five pieces.
We construct ours of a suitable metal body shaped externally similar to those in
present use the top being recessed out for rubber washer packing. From the top to
the enlarged part where bottle neck fits into is a quarter or passage screwed for a
spindle to work through. This spindle is about two inches long and is turned plain at
the top without a thread for about three quarters of an inch and is screwed about of
$
inch of its length the remainder at the bottom has a conical flange shaped ending
which acts as a valve as will hereafter be shown in final specification with drawings.
This valve is part and parcel of the screwed spindle and in putting the syphon
together we insert the spindle from the under surface where it connects to the bottle
neck. After screwing it into position a circular disk with a milled edge is rivetted on
top of spindle or a cross bar. The bottle neck is fitted with a flanged tapered piece
of indiarubber with a 3 in. tapered to quarter hole through it for the insertion of the
glass tube. A screwed split ring similar to those now in use affixes the syphon top to
neck of bottle in the usual way the upper portion of the washer is the valve seating
and the pressure of the syphon top being screwed to the split ring makes a tight joint
of the glass tube which of course is a necessary piece of the mechanism.
Briefly our syphon top consists of screwed spindle rubber washer glass tube split
ring and syphon body, circular disk at top being part and parcel of spindle when
rivetted on.
Its action is simply screwing and unscrewing by the disk which opens
and closes the valve against the rubber washer seating.

page_text: The chief feature of our improvement is by screwing and unscrewing the spindle
and not by pressure on a lever. Apart from simplifying the construction of the
syphon top we effect the very desirable object of increasing the orifice for the passage
of the aerated water from the bottle to the glass and this increase in the volume of
aerated water effects the sharpness of the waters. The complaint of the flatness is
the chief objection to the use of syphons as at present constructed. We do not
confine ourselves exclusively to the construction of our syphon in every detail as
hereinbefore described as for instance we may use a glass tube and washer similar to
those now in use leaving a raised ledge on of the metal part of glass tube as the valve
seating and allowing a suitable valve to fit on same screwing and unscrewing down.
the valve instead of pressing on a leaver We alter the construction of the bracket part
that holds the syphon bottle in filling machine to screw and unscrew spindle instead of
pressing on leaver. The tops of syphon bottles as now constructed have a lever which
is pressed down to open the valve when being filled by means of a handle lever
attached to bracket of syphon filling machine. In place of this handle lever we place
a revolving handle at the bottom extremity of the bracket where the syphon top fits
into. This handle grips the disk on the spindle of syphon top and screws it up or
down as required to open & shut in the process of filling this is done to suit the
altered construction of syphon top.

WILLIAM BRUCE Mineral Water Engineer 13 Randle Street Traninere, and WILLIAM
THORNE Mineral Water Manufacturer Atherton Street Birkenhead both in the County
of Chester, do hereby declare the nature of our invention for IMPROVEMENTS IN THE
CONSTRUCTION OF THE TOP OF SYPHONS & FILLING MACHINE and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
Syphon Tops consist of ten or twelve seperate pieces, viz. Syphon Top body, cap,
leaver, handle, piston rod, valve, spiral spring, India rubber washer, rounded tube, do
small round spindle, metal do for stuffing box metal ring round neck, glass tube with
metal washer. Our design enables us to construct a syphon top in about four pieces,
viz Syphon Top body spindle & valve with disk button top or cross bar, all in one
piece when put together Tube India rubber washer, and metal ring round neck of
bottle, and small brass nipple. The following lettered description, correspond with
the accompanying drawings. No. 1. Body of Syphon Top we cast preferably in pure
block tin or other suitable alloy with sufficient lead to allow it seperating from the mold
freely say 95 per cent pure tin. It is cast with the nozzle at such an angle as to
admit it leaving the mold freely and the nozzle is placed a little lower down on the
shoulder of the body so that when the spindle valve is opened there is a clear passage
for the inlet of carbonated water when charging the syphon and a free outlet of same
diameter as the tube from the extremity of the nozzle to the end of the glass tube in
the glass bottle when emptying the syphon bottle This is a special feature in ours not
obtainable in those now in general use and the advantage we gain is the extreme
sharpness of the waters for it is well known though syphons are charged at such a
high pressure the waters are flat in comparison to bottled goods. This is caused by the
water having to pass through a very small passage the piston rod in old syphon tops
filling up the space the valve seating being on the syphon body. In ours it is on the
metal surface of the glass tube. Our syphon tops body is screwed with a deep coarse
pitch thread for the spindle valve to screw into and at the enlarged top extremity it is
screwed for a small brass or block tin nipple to keep packing round spindle. The
enlarged base of the syphon top body is internally screwed for a brass or metal ring
securing it to the bottle neck in the usual way. There is no turned valve seating on
tho syphon head body.
2. Screwed brass spindle valve tinned or silvered this is made of best gun metal and
is turned sincoth at top extremity where it works through the stuffing box.
The body of spindle is screwed to same pitch thread as on syphon top body and the
top of spindle is squared for a crosshead or button disk. The valve at lower extremity
of spindle is turned slightly conical to the shape of the metal inside of flange on top
of glass tube and has a groove turned for a suitable rubber or leather washer and the

page_text: syphon top body has a turned recess for the valve to work in when opening & closing.
The conical portion of the valve that fits into the tube has a hole bored out same
diameter as the glass tube on the under side with one or two outlet holes at the side
just below the washer that when the syphon bottle is opened these holes on the side of
the valve leave a clear channel for the aerated waters up the tube through the under
surface of the valve and out of the side holes down and out of the nozzle.
The valve & spindle may either be in one piece or the valve cast on so as to revolve
on spindle.
3. Brass nipple about in. diameter to keep packing round the upper smooth part of
spindle. Glass tube with metal flange at top constructed like those in present use but
has a slightly raised upper surface on the metal part smooth and true for the valve
seating. Round the metal flange is the rubber washer for making the bottle part
secure to syphon head in the usual way.
We can substitute a rubber washer shaped like the metal flange on top of tube and
insert a glass tube in it and the upper surface to be the valve seating.
5. Cast iron Bracket Syphon holder shaped to suit the altered construction of syphon
top. When placed on the spindle and acted on by treadle it holds the nozzle of
syphon bottle to its proper position while being filled and instead of having a handle
to press the leaver of syphon top it has a revolving base where the button disk or cross
head on extremity of spindle of syphon fits into. This revolving base is acted on by
a suitable handle as shown in illustration and opens and closes the syphon bottle by
screwing and unscrewing the spindle valve of syphon top.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to he performed we declare that we claim is
1st. The syphon top body in regard design principle & mechanism.
2nd. The mechanical construction of the screwed spindle & the principle of opening
& closing the valve by screwing & unscrewing. The spindle being made either in one
piece of casting with the valve or spindle made of gunmetal and the valve of block tin
cast on to extremity of spindle in such a manner as to revolve on the spindle which is
what we preferably do to lessen friction on valve seating.
3rd. Button disk or crosshead on top extremity of spindle.
4th. The substitution of a rubber top to top extremity of glass tube if found
preferable to block tin top which forms the valve seating.
5. The cast iron bracket for holding the syphon against the syphon filling valve and
screwing & unscrewing the spindle during the process of charging the syphon with
carbonated water instead of pressing on a leaver.
