Improvements in and relating to Coinfreed Apparatus for Delivering
Fermented or Aerated Liquids.
I FREDERICK KEARSLEY 54 Barlow Moor Road Chorlton cum Hardy near
Manchester Commercial Traveller 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:-
This invention consists of an improved arrangement of coin freed mechanism
whereby the contents of a cask or barrel of beer, stout or other like beverage can
be drawn off by the prepayment of a fixed coin for a given quantity (say one glass)
and further in an improved construction of stillage apparatus whereby the cask or
barrel may be enclosed under lock and key and under the control of the person
responsible for payment.
It will thus be understood that my invention will enable a family whose circum-
stances would not admit of the purchase of a barrel of beer or stout in one payment
to be supplied with the same by paying for the liquor as it is consumed the total to
pay for the contents of the entire barrel.
.
In performing my invention I mount the cask in an improved form of enclosed
stillage (hereinafter described, and forming the second part of my invention.)
and I provide the said cask with the usual bib tap, but I connect such
bib tap by means of a flexible tube which permits of the automatic tilting
of the barrel with an additional or supplementary tap conveniently placed
below the level of the cask. This additional tap consists of a plug and
outer casing or barrel provided with ports and passages for the passage of the
liquid, in the manner hereinafter described.. Upon the one extremity of the said
plug I mount a receptacle of capacity sufficient for say one glass of beer. or other
liquid which receptacle is in communication through the plug passages and flexible
tube with the barrel and upon or near the other extremity I mount a cam disc.
provided with a notch or recess into which takes a tooth upon the shorter arm of a
pivoted lever, the other or longer arm of which lever is capable of being depresseil
by the weight of a suitable coin falling upon the same and thus releasing the tooth
from the notch in the cam disc and permitting the plug to be turned and the contents
of the receptacle drawn off.
In order to make my invention the better understood and carried into practical
effect I have hereunto aunexed. two sheets of drawings and will now proceed to
describe the same with assistance of the various figures and letters of reference
marked thereon.
The first sheet of drawings shows only so much of a cask as is necessary. to
enable the application of my invention thereto to be understood.
Fig. 1 is a front and Fig. 2 a side elevation of as much of my invention as is.
necessary to illustrate the coin freed and draw off mechanism whilst Figs. 3 and 4
are sections of the supplementary tap and receptacle.
In its normal position, as illustrated in Figs. 1, 2, and 3 the receptacle A is in
open cominunication with the barrei B through the bib tap C, flexible tube D and
supplementary tap E, and the passage to the draw off spout F is closed.

The plug G which carries the receptacle A is prevented from being turned by.
the tooth H on the lever 1 which is pivoted at 1' engaging with the notch J in the..
cam disc K, but upon the insertion of a coin which falls down the slot L
upon the
other extremity 1 of the lever raising the tooth H out of the notch J the plug and
receptacle can be turned by a suitable key, as seen in Fig. 4, and the contents of

page_text: the receptacle passing along the passage G in the plug may be drawn off through
the spout F, the communication between the cask and receptacle being closed as
illustrated.
After falling upon the lever I and raising the catch H, the coin is retained upon
the extremity of the lever by the shorter arm I coming in contact with the rubber
or other spring N until the plug G is turned, when the cam disc K further raises
the shorter arm 1' and consequently depresses the longer arm I' and the coin is
released.
In order to counteract the pressure of the outer atmosphere and allow for the
free withdrawal of the liquid contained in the receptacle A, I provide a spring
air valve A' which is actuated by catching against the bowl or projection O,
when the receptacle is reversed.
The inlet or receiver vent P, and the vent Q in the barrel top are both connected
with an air pump R, (see Figs. 5 and 6) the plunger R' of which is actuated
by drawing back a sliding plate S which covers the entrance to the coin slot L,
and which necessitates the working of the air pump at each drawing off of the
liquid. The port Q₁ connected by a flexible tube T to the vent peg T' in the
top of the cask is closed by the plunger R' immediately the same is forced
forwards by the sliding plate.
The process of drawing a glass of beer may be described as follows:-
The receptacle A is in the position shewn in Fig. 3 but as the air in the said
receptacle cannot escape owing to the vent tube P being filled with the liquid
which has risen to the level in the barrel the said receptacle remains empty of
liquid until the slide S which covers the coin slot L is drawn back and the air
pump plunger R' being actuated drives down the obstructing liquid in the vent.
tube P and the air in the receptacle A escaping by the tube P pump R port Q
tube T and vent peg T¹ into the atmosphere the liquid from the barrel flows into
and fills the receptacle. A coin having been inserted in the slot L falls upon the
lever releases the catch or tooth H out of the notch J and the plug G and
receptacle A being reversed (see Fig. 4) the spring vent valve A' is actuated,
admitting air into the receptacle A and the liquid flows out through the draw off
spout F. The receptacle is held in the inverted position until the same is emptied.
The further turning of the cam disk K brings the cam into, operation and further
raises the shorter arm 1 of the lever 1, which had previously come into contact
with the spring or rubber stop N and the longer arm I being thereby further
depressed the coin falls into a receptacle placed to receive it and the receptacle A
and plug G are again in the position shewn in Fig. 3. These operations are
repeated until the barrel is emptied..
On Sheet 2 of the accompanying drawings I have illustrated by front views
Figs. 7 and 8 and side sectional view Fig. 9 the stillage I employ in carrying out
my invention and which consists of a casing comprised of three sides a, a¹ and a²,
supporting the cross bars or stay pieces c and d for carrying the cask e and the
cross bar to which the supplementary tap E is attached see Fig. 2 Sheet 1. In a
hole provided for the same in the rear cross bar d is fitted a tube or casing g
containing a spiral spring whose function is to automatically tilt the barrel as the
contents become exhausted and the tension of the said spring diminished.
I provide this improved still with a removable front h and top k for the purpose
of replacing and attending to the casks and coin freed mechanism, and I provide
the rear edge of the said top with pins / taking into holes m provided for them in
the uprights n and I also provide the lower edge of the front with a catch
piece o taking under the cross piece p as illustrated. It will thus be seen that when
the front h and top k are placed in position with the pins in their respective holes
and the catch piece o in position and the staple q, which is attached to the top k,
passed through a hole in the front h the whole may be securely locked and the
contents preserved from interference by means of a pad-locks passed through the
said staple g (see Fig. 9). ·

page_text: Having thus particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In my improved coin freed apparatus for the supply of beer stout and other
like beverages in prepaid quantities, the use and employment of a supplementary
tap, coupled to the ordinary tap in the barrel with an elastic or yielding coupling
and fitted with a receptacle and cam disc and in combination with a toothed lever
all mounted and operating substantially as described and illustrated on the
accompanying drawing.
2. In combination with the supplementary tap or receptacle the general
arrangement of venting appliances substantially as and for the purposes described
and illustrated.
3. In combination with the said supplementary tap receptacle releasing
mechanism and venting appliances the general construction of closed stillage
employed substantially as described and illustrated.
Dated this 2nd day of October 1893.
