PROVISIONAL SPECIFICATION.
Improved Means for Fixing the Glass Tubes of Syphons.
EDWARD RUSSELL VAUGHAN Engineer 3 Sydney Terrace South Parade City of
Belfast do hereby declare the nature of this invention to be as follows:-
The making of the piece A; as shewn in drawing, of Vulcanite or other suitable
nonmetallic material. On the hollow or inner portion of which there is a fine
screw.
B is a piece of India Rubber tube or other suitable material, such as Cork &c.;
which is placed round the Tube C-which is slightly enlarged at end as shewn.
When the India Rubber tube is put round the Tube C; it can then be screwed into
the piece A; and is so retained in position as shown.

COMPLETE SPECIFICATION.
Improved Means for Fixing the Glass Tubes of Syphons.
1. EDWARD RUSSELL VAUGHAN of 3, Sydney Terrace, South Parade, Belfast,
Engineer, do hereby declare the nature of this invention and in what manner
the same is to he performed, to be particularly described and ascertained in and by the
following statement, reference being also had to the drawings filed with my Provisional
Specification:
The method hitherto adopted for fixing the glass tubes of syphon vessels or
receptacles for containing aerated waters or other beverages has, necessitated
the use of a metal cap on the top of the glass tube at the mouth or opening
of the containing vessel, such cap having been cast direct on to the top of
the tube and thus forming a rigid non-yielding "fast" joint at the point of connection.
This method of attachment which has previously obtained, is open to serious
objections and drawbacks, amongst others which might be enumerated I may mention
the following, firstly -The containing bottles or other vessels when in course of
transit are liable to assume such a position, as to bring the contents in contact with
the under surface of the head of the cap aforesaid which latter when made of any of
the ordinary metals usually employed with syphons, would, to a certain extent
contaminate, deteriorate and render more or less injurious the contents of the vessel,
Secondly-another disadvantage attaching to the system hitherto adopted, is, that
inasmuch as the glass tube and the metal cap are virtually in one piece, hence it
follows, that in the event of the glass tube being broken the whole tube with the
metal including the valve seating at top is rendered useless.
Now, it is with a view to obviate the drawbacks and disadvantages above pointed
out that the device according to my Invention is devised. In accordance therewith I
employ a cap piece or connection A (shown in the accompanyings) of any suitable
non-metallic material such for instance as vulcanite; ivory, hard wood or the like; the
interior of same being formed with a screw thread. A short tube or collar B of india
rubber or like resilient material is fitted over the glass syphon tube C the end of the
latter being slightly enlarged as shown in order to retain said tube or collar B in
position on the glass Syphon tube aforesaid. The cap piece or connection A is
screwed over the rubber tube or collar B thus forming a flexible but yet withal a
herinetically sealed joint between the cap piece or connection A and the glass syphon
tube C aforesaid whilst at the same time the glass tube C and india rubber tube or
collar B can be screwed out of the cap A at will.

page_text: In will also be obvious that in accordance with my Invention the disadvantage
which at present obtains of the continual wear of the valves arising from the
employment of a metallic valve seat to which the rubber composing the valves has a
great tendency to adhere is entirely obviated.
I wish it to be understood that although as I have above pointed out by my improved
system entirely dispense with the necessity for the employment as hitherto of a
metal cap piece, still, it, will, he obvious that should in any case the employment
of metal he desired and especially when the metal composing same would not, have an
injurious effect upon the liquid contents of the containing vessel, the system which
I adopt as hereinbefore described whereby I form a separate means of attachment
would also allow of the adoption of a cap.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
First. In fixing the glass tubes of syphons, the employment of a detachable
flexible junction device, instead of as hitherto a rigid "fast" joint substantially as
herein set forth.
Second. In the improved means for fixing the glass tubes of syphons herein
described the employment in combination with the india rubber tube or collar B
adapted to the glass syphon tube C of the detachable cap piece or connection A
formed with an internal screw thread, substantially as and for the purposes herein
described.
