HARRY STUART DIX Shelton Brewery, Hanley Staffs, Brewer do hereby
declare the nature of this invention to be as follows:-
An indiarubber vessel for the purpose of drawing the air out of a syphon tube,
shaped in the form of a bottle having a graduated neck which, when slipped on the
tube of the siphon makes an airtight joint. The bottle after being compressed
expands and so draws the air out of the tube.
An Attachment for Starting Syphons.
I, HARRY STUART DIX, of Shelton Brewery, Hanley, Staffordshire, Brewer,
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 :—
My invention relates to an attachment for starting syphons employed in breweries
and elsewhere and consists in the employment of an attachable and detachable
self-dilatable vessel secured to the nozzle end of the longer leg of the syphon when
in a collapsed condition and during the time that pressure is being applied to the
same by the hand, so that when released after being placed on the said syphon end,
it then expands itself to its normal dimensions, by which latter operation, the air
lying between the said dilatable vessel and the liquid to be drawn from one vessel
to another is rarefied and the syphonic action started.
The syphon starter, which may have an expanding neck, is preferably made of
india rubber and with its walls of such a thickness as to be capable of re-acting
and expanding the vessel when compression thereon is released, so as to thereby
suck the air into it for the initial starting of the syphon.
Figure 1 of the accompanying drawing represents a syphon-starting attachment,
preferably made of india-rubber, and constructed in accordance with my invention.
Figure 2 represents a bottling syphon, with my starting attachment collapsed by
the pressure of, and held in the hand and in the act of being slipped onto the
nozzle of the long leg.
Figure 3 represents the said syphon attachment expanded by the dilation of the
walls of the same, on pressure upon it being relieved, whereby the air in the said
long leg is rarefied and the liquid is caused to rise up the short leg, pass over the
head and descend down the long leg, into the starter, with a stratum of air
compressed between the head of liquid and the bottom of the vessel.
The starter is then drawn off the end of the leg and the liquid continues to run
consequent upon the predominating weight of liquid in the longer leg.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
a is the body of the starter, with thick side and bottom walls a¹, a³, an expansible
and contractible neck a³, inside coned at at, and having an inwardly extending and

page_text: contracted throat a³, to admit of the said neck being placed upon any sized syphon
end, within certain limite.
Instead of making the starter from india rubber, I may make the same from any
suitable material, such as silk, flexible metal or leather. "Where metal is employed,
then preferably only the opposite sides are compressible and expandible; or as a
modification a side may be fitted with a rubber diaphragm, which is pressed inwards
before the starter is fitted to a syphon end and then when pressure is relieved, the
inside dimensions are restored either by its own elasticity or through the medium
of a spring.
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 I
claim is :-
First. A starting attachment for syphous consisting of a vessel having a
collapsible and self-expanding body or part of a body, substantially as and for the
purpose described and set forth.
Secondly. A starting attachment for syphons consisting of a collapsible and
-self-expanding vessel having elastic walls of sufficient thickness to restore the same
the said vessel to its normal dimensions on pressure being relieved, substantially as
described and set forth.
• Thirdly. A starting attachment for syphons consisting of a collapsible and
self-expanding vessel with a coued and inwardly extending throat, substantially as
and for the purpose described and set forth.
Dated this 2nd day of December 1895.
