PROVISIONAL SPECIFICATION.
Improved Coin-freed Apparatus for Delivering Liquids.
I, THOMAS JAMES CARTER, of 4 and 8, Broad Street, Margate, in the County
of Kent, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for enabling liquid to be withdrawn from a
vessel on the insertion of a coin of predetermined value, the said apparatus being
especially designed for use in connection with syphons containing aërated liquids.
In carrying out my invention I provide a suitable stand for the syphon having a
hollow base and provided with a bracket or swan-neck having at the upper part a
clip or holder for receiving the head of the bottle. In the swan-neck, which is made
hollow, is arranged a sliding rod the upper end of which is designed to normally
press against the underside of the lever by means of which the syphon valve is
opened, so that the said valve-operating lever cannot be depressed until a coin is
inserted to release it. Any suitable arrangement of coin-freed mechanism may be
used for holding the rod, for instance, a pivotted lever may be arranged in the
hollow base, one end of which engages with rack teeth on the lower end of the said
rod whilst the other end is adapted to be acted upon by the coins inserted into the
apparatus so as to disengage the lever from the rack.

1, THOMAS JAMES CARTER, of 4 and 8, Broad Street, Margate in the County
of Kent, Sanitary Engineer, 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 apparatus for use in connection with syphons for con-
taining aërated liquids for enabling liquid to be withdrawn on the insertion of a coin
of predetermined value.
•
In carrying out my invention I provide a suitable stand for the syphon having a
hollow base and provided with a bracket or swan-neck having at the upper part a
clip or holder for receiving the head of the bottle. In the swan-neck, which is made
hollow, is arranged a sliding rod the upper end of which is designed to normally
press against the underside of the lever by means of which the syphon valve is opened,
so that the said valve-operating lever cannot be depressed until a coin is inserted to
release it. Any suitable arrangement of coin-freed mechanism may be used for
holding the rod, for instance, a pivoted lever may be arranged in the hollow base,
one end of which engages with rack teeth on the lower end of the said rod whilst the
other end is adapted to be acted upon by the coins inserted into the apparatus so as
to disengage the lever from the rack.
To enable my invention to be fully understood I will describe the same by

page_text: reference to the accompanying drawing, which represents a vertical section of
apparatus, for delivering aërated, liquid, constructed according to my invention.
a is the stand for the syphon, the hollow base thereof and e the bracket or
swan-neck.
The upper end of the bracket c is provided with a socket d through which passes
a rode having at its lower end a cap adapted to fit on the top of the syphon g.
h is a set screw adapted to be operated by the key for securing the cap fin
position on the top of the syphon. is a spring for releasing the syphon when the
screw his loosened.
jis the sliding rod arranged in the hollow bracket and k is the lever operating
the syphon, against the underside of which lever the top of the sliding rod j
normally presses so that the said lever cannot be depressed until the pressure of the
rod on its underside is removed. The lower end of the sliding rod; is made hollow
and contains a spring / which presses against a stop m whereby when pressure on
the lever is removed the sliding rod jis forced to move upwards. n is a flange on
the sliding rod, the said flange being adapted to limit the upward movement of the
said rod by its contact against the lower end of the bracket or swan-neck c as shewn
in the drawing.
The mechanism for releasing the lever k is arranged in the hollow base 6 of the
stand a.
o, o is the bell-crank lever pivoted at p to a vertical bracket g. The
short arm o of the bell-crank lever is made somewhat broad and is of such a shape
that it is supported on the bottom of the stand and that it can act as a pawl to
engage with the teeth of a rack r formed on the lower end of the sliding rod j
.thereby locking the same in its upper position. s is the coin chute curved as shewn
so as to cause the coins to drop on to the long arm o' of the bell-crank lever thereby
releasing the arm o from the rack r so as to allow the lever k to be depressed. tis
a lever pivoted to the top of the vertical bracket g, one of the ends of the lever
being bent at right angles, as shewn, for the purpose of retaining the coin in the
chute and the other end being inserted in a hole in the lower end of the sliding
rod j. u is the drawer or till for receiving the coins dropping from the chute.
For the purpose of allowing only a predetermined quantity of liquid to be drawn
off when a coin has been inserted in the machine I make the tube of the syphon of
a size and capacity corresponding to the quantity of liquid to be discharged and
I provide the said tube v with a contracted neck and within the tube I place a
ball of glass or other suitable material adapted to rise in the tube as liquid is
withdrawing and stop the flow of liquid through the contracted neck w when it
reaches the said contracted neck.
The operation of the apparatus is as follows:-A coin is inserted into the chute s
and drops on to the end of the arm o' of the bell-crank lever thereby depressing
the same and disengaging the short end o of the said lever from the rack r. If the
syphon lever be now depressed the rod j is forced downwards and the valve of the
syphon is opened thus allowing the quantity of liquid contained in the tube y to
escape, the How being stopped by the arrival of the ball x at the contracted neck of
the tube as shewn in dotted lines in the drawing. The depression of the sliding
rod; has lifted the bent end of the lever t thus allowing the escape of the coin from
the chute into the till. When the liquid has ceased to flow from the syphon, the
lever is relieved from pressure, the sliding rod j is pressed upwards against the
underside of the same by the force of the spring 1, the lever t again drops, the arm o¹
of the bell-crank lever is again drawn up into its normal position by the short arm o
which re-enters into engagement with the rack on the lower end of the sliding
rod and the ball a drops to the bottom of the tube leaving the latter filled with
liquid.
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 :-
1. Apparatus for supporting a syphon buttle for aërated liquids and provided.

page_text: with coin-freed mechanism whereby the valve will be retained locked until a coin
be inserted in the apparatus to release the saine, substantially as, and for the purpose,
described.
2. In coin-freed apparatus for delivering aërated liquids from a syphon a stand
containing coin-freed mechanism and a vertical bracket coutaining a sliding rod
adapted to be locked by the said mechanism and to control the movements of the
syphon lever, substantially as described.
3. In coin-freed apparatus for delivering liquids, of the kind described in Claim 2,
a bell-crank lever one arm of which is adapted to engage with a toothed portion of
the sliding rod and the other arm to be operated by a coin, substantially as, and for
the purpose, herein before described.
4. The combination with coin-freed apparatus of the kind described in Claim 2 of
a syphon bottle the tube of which has a contracted neck and is provided with a ball,
as, and for the purposes, herein before described.
5. The improved coin-freed apparatus for delivering aërated liquids hereinbefore
described and illustrated in the accompanying drawing.
