COMPLETE SPECIFICATION.
Improvements in Syphon Bottles.
THOMAS HOWELL WILLIAMS of 10 Ascham Street Kentish Town N.W.
Manufacturing Chemist and WILLIAM HENRY SYMONS of 130 Fellows Road
South Hampstead Consulting Chemist do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of our present invention is to further improve the syphon head
referred to in our Amended Complete Specification No. 12391 of 1890 so that the
liquid contents shall not come into contact with any metal whatever more especially
at the nozzle or outlet of the spout and to render the construction of the said
syphon head easier and cheaper and also to prevent breakage or damage in filling
and handling such syphons.
Whenever the contents of the syphon are withdrawn a drop of the liquid
invariably collects on the lower portion of the nozzle of the spout and where the
spout is lined with glass or non-metallic substance such drop overlaps the edge of
the glass or non-metallic substance and comes into contact with the edge of the
metal casing outside and corrosion of the metal may take place where the contents
are in anywise acidulous. Moreover in filling the syphons there is a great wear
and tear on the edge or end of the nozzle which is likely to cause the fracture
of the glass or non-metallic lining.
These difficulties we propose to obviate either by prolonging the non-metallic
lining of the spout beyond the metal casing for about or gths of an inch the lining
being thickened and enlarged beyond such casing so as to cover the edge of
the metal casing and also to give greater strength to the lip or edge of the non-
metallic lining itself as represented in Figure 1 or instead of enlarging the end of
the non-metallic lining itself such non-metallic lining may be made to project
for a short distance beyond the metal casing and have a collar or ring of vulcanite
or other suitable non-corrosive substance of a proper size to tightly encircle such
lining and join the metal casing to both of which such collar or ring can be
cemented or screwed or otherwise suitably attached as shewn in the drawing
Figures 2, 3 & 4 & so strengthen the part brought into contact with the filler or
the glass or other lining of the spout may be made to cease about inch or so
from the outlet end of the metal casing and a tip of vulcanite or other non-
corrosive and preferably non-metallic material inserted with an indiarubber or
other suitable washer or seating if desired as shewn in Figure 6 and such tip may
be cemented in or preferably secured by means of a union joint or the cut screw or
bayonet catcher in the same manner as hereafter described for securing the loose
valve box in the metal casing and thereby enabling a stronger tip to be inserted
during the operation of filling the syphon..
In fixing the spout as described in our said Specification No. 12391 of 1890 we
find it sometimes more convenient instead of having both parts of normal tem-
perature to raise the temperature of the metal casing of the head containing the
aperture into which the spout is to be inserted and also the loose valve box where
same is made of a material sufficiently expansive such as glass under the influence
of a moderate temperature to a convenient heat say 150° C. so that when the spout
is slipped into the aperture the contraction thereof as it cools tends to hold the
spout firmly fixed in position & the joint is thereby rendered inore perfect.
A suitable cement such as that made from isinglass copal damnar or resin or a
mixture of 2 or more of these or other suitable material may be applied at
the points of contact between the spout and the aperture before joining same
and the spout may if desired be further secured by soldering pinning or screwing

page_text: the metal portions together or to the non-metallic portions or the metal portions
may be bound together by a common screw union joint so as to permit of the
easy removal of the spout.
The loose valve box described in our said Specification No. 12391 of 1890
and shewn in Figure 5 may be rendered in some points more serviceable by having
a screw thread run on its outer surface corresponding with a female screw made to
receive it in the metal casing of the syphon head so that when it is screwed
into such metal casing it may be retained more firmly in its proper position or the
same object may be obtained by having such male and female screws cut away in
complementary portions so that the valve box may be slipped in and secured by a
slight turn or the same object may be secured by having studs or projections on the
outer surface of such valve box with corresponding suitable grooves or galleries
formed in the interior of the metal casing of the syphon head to receive same such
grooves or galleries being first of all made perpendicularly for a short distance
from the bottom of the metal casing towards the top and then turned off at
an angle preferably rather larger than a right angle for a distance of or of the
perimeter of the casing so that when the valve is inserted & slightly turned it may
be held securely in its place in a manner somewhat similar to the old bayonet catch
or the studs or projections may be made in the interior of the metal casing of the
syphon head itself and the grooves or galleries in the loose valve box but without
perforating same so that in any case when the valve box is put in it may be firmly
secured whilst at the same time it may be readily removed in case of repair being
required.
We wish it to be understood that we are aware that it has been before proposed
to line the interior portions of syphon heads with non-metallic substances and we
lay no claim at large to such construction.
The drawings are given by way of illustration and we do not bind ourselves to
the particular forms there delineated.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim are:-
1. The improved spout with the non-corrosive tip either fixed or removable
as above set forth.
2. The improved loose valve box as above described.
