Improvements in Syphon Bottles.
THOMAS HOWELL WILLIAMS of 10 Ascham Street, Kentish Town, N.W. Manu-
facturing Chemist and WILLIAM HENRY SYMONS of 130 Fellows Road South
Hampstead Consulting Chemist, 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 :-
The object of our present invention is to construct syphons so that the liquid con-
tents shall not come into contact with any metal, but at the same time in such a
manner that the syphons shall possess the necessary strength to resist the usage
incidental to filling, transit etc.
To accomplish this we have those portions of the syphon over which the liquid passes
made of some nonmetallic substance, such as earthenware, glass, vulcanite india
rubber or a combination of these with some other nonmetallic substance and in order
that these parts may be protected from injury we have them covered with metal either
as a loose case or cast on the nonmetallic substances or screwed to them or we may
employ any of these methods or a combination of them.
That the nature of our invention may be better understood we furnish herewith
sectional drawings and will proceed to describe our improvements with their aid.
Fig. 1 represents a section through one form of syphon head to which the improve-
ments are applied.
The numerals refer to the figures under which those parts are particularly described.
Fig. 2 represents a portion of the outside case which is made of metal preferably
tin or some alloy of tin. It fits over the valve box and secures it to the glass vase
the joint being mado air tight by a rubber washer and the ordinary split screw.
Fig. 3 represents a section through valve box which is made of earthenware, glass
or some other non metallic substance.
The long tube of the syphon fits into the lower portion of the valve box being
adjusted with india rubber, or it may be in one piece with the valve box.
Fig. 3' shows another forum which differs only in the seating.
Figs. 4 and 4' represent the two forms of pistons for use with the above. These
are of vulcanite, earthenware, glass or some other nonmetallic substance covered
partially with india rubber or the lower part may be of nonmetallic material and the
upper part of metal.
Fig. 5 represents the spout made of glass or other nonmetallic substance covered
with metal, the nonmetallic tube projecting one end beyond the motal as shown in the
figure.
The metal casing of the spout fits somewhat loosely into the aperture (a) of the
casing Fig. 2, and the projecting nonmetallic portion fits more accurately into the
aperture (a) of the valve box being ground to fit either directly or with a washer
intervening or it may be cemented in.
When the nonmetallic portions have been thus united the metal casings are joined,
preferably by solder.
The piston then being placed in position with the lever and spring, the syphon is
ready for filling.
We wish it to be understood that we are aware it has been before proposed to
make those portions of the interior of siphon heads with which the liquid comes

page_text: in contact of nonmetallic material and that we lay no claim at large to such
construction.
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.
First. The improved syphon head consisting of a loose nonmetallic valve box
protected by a metallic casing fitting over the same, substantially as hereinafter
described.
Second. The improvements in the method of connecting the spout to the valve box
and to the metallic casing substantially as set forth.
