PROVISIONAL SPECIFICATION.
Improvements in and connected with Coin Freed Apparatus for
Delivering Measured Quantities of Liquid from a Cask, Jar, or
Bottle.
I, WILLIAM SHERAR, of No. 49, Gladesmore Road, Stamford Hill, London,
in the County of Middlesex, Accountant, do hereby declare the nature of this
invention to be as follows:-
This invention has reference to coin freed apparatus of the kind described in the
Specifications of my Letters Patent No. 18380 of A.D. 1893 and 20083 of
A.D. 1894 by which apparatus measured quantities of beer or other liquid may
be extracted from a cask jar or bottle by the insertion of a coin in the said
apparatus.
The objects of my present invention are firstly, to so construct the head of the
cask or barrel to which my said apparatus is to be applied as to afford more room
for the coin freed apparatus to be fixed thereto or formed therewith; secondly, to
provide means whereby the tap hole in the head of the cask or barrel can be
opened or closed independently of the coin freed apparatus so as to enable the said
apparatus to be removed from or fixed to the cask or barrel at any time when
required by the brewer or other authorised person; thirdly, to enable the cask to
be vented through the tap hole; fourthly, to provide means for closing the money
slit to prevent the insertion of a coin wheu the cask bottle or jar is empty; and
fifthly, to provide means for indicating the number of measured quantities of
liquid which have been withdrawn from the cask bottle or jar and also indicate
when the cask bottle or jar is full and empty.
To attain the first object of my invention 1 make the head of the cask or barrel
of metal, preferably of sheet brass, the periphery of the head being turned out-
wardly so as to engage in the groove of the staves where the usual wooden head
fits. As the metal head is comparatively very thin 1 thus obtain for the coin
freed apparatus an additional space almost equal to the thickness of the usual
wooden head. My improved metal head may be corrugated or stayed or ribbed
so as to strengthen the same. The metal case containing the coin freed apparatus
is fixed to the metal head by any convenient means; or the metal head may be
made in a box like form so as itself to form the casing for the coin freed apparatus
and the measuring compartment of the same.
According to one method of carrying out the second part of my invention
I provide a metal thimble which is fixed in the tap hole in the head of the cask
or barrel, as by screws passing through a front flange of the thimble into the head
of the cask or barrel. Free to turn in this thimble there is a tubular bush
provided with a flange on the outside of the thimble which is by preference made
with spur teeth cut in its periphery so that it can be turned by a pinion like key
from the outside. This bush is screw threaded inside and its inner end is provided
with a metal plug which is screw threaded and can turn freely in the bush and is
made with a bevelled flange or otherwise formed at its inner end so as to close
the end of the plug when screwed up tightly thereto. The spigot end of the
measuring tap of the coin freed apparatus is screw threaded so as to fit into the
said bush and the end of this spigot is provided with a square projection or is
otherwise formed so as to engage with the plug and turn the same as hereinafter

page_text: described. There are side grooves or passages in the plug through which, when
the plug is screwed outwardly from the bush as hereinafter described, the liquid
can flow from the cask into the tap of the measuring device.
The above described tap hole closing device is operated as follows:-I will
assume that the coin freed apparatus has been removed from the head of the cask
for some purpose and that the tap hole in the said bush is closed by the said plug
screwed tightly in the inner end of the same. The coin freed apparatus is placed
in position on the head of the cask, the projection on the spigot of the measuring
tap entering the bush and engaging with the hole or recess in the plug. The bush
has now to be turned by the pinion key engaging with the teeth on the flange of
.the bush. This has the effect of drawing the spigot into the bush and screwing
the plug out of the same until ultimately the flange of the bush will bear against
a washer on the case of the coin freed apparatus and prevent leakage, the liquid.
being free to flow through the channels in the plug and through the bush and tap
into the measuring device. Before the coin freed apparatus can be removed from
the head of the cask or barrel the bush has to be turned by the pinion key in the
opposite direction to that above described, so as to screw the plug back into the
bush and close the tap hole and at the same time screw the spigot end of the tap
out of the bush. In this arrangement of the second part of my present invention
the tap is immediately in front of the thimble and bush in the cask but in a
modification of this part of my invention I arrange the tap at one side of the
thimble when viewed from the front of the cask and
arrange the said screwed
bush (by which the plug is turned) in a screw threaded hole through the solid
metal of the casing of the apparatus so that the said bush and the plug can be
turned from the front of the apparatus without the use of the toothed flange of the
bush and the pinion key. In this case the liquid enters the inner end of the bush
and flows out of a side hole or holes therein and into a cavity or passage leading
to the said tap by which the inlet and outlet from the measuring chamber are
controlled. I may provide a similar arrangement of thimble plug and bush for
the vent hole into the cask which thimble plug and bush will be arranged at one
side of the tap hole which regulates the air inlets into the cask and into the
measure as described in the Specification of my prior Letters Patent No. 20083°4,
this bush being operated by a screw driver or by other means from the front of
the apparatus so that the vent passage into the cask or barrel can be opened after
the apparatus has been fixed to the cask thus preventing any wasting of the contents
through the vent hole.
To attain the third object of my invention I provide a passage in the casing of
the apparatus leading from the bush in the tap hole to the air inlet or vent which
is controlled by the tap as described in the Specification of iny said prior Letters
Patent so that when the bush is turned to screw the plug into the thimble and
close the tap hole, the vent will be closed also to prevent the escape of liquid
through the vent and when the bush is turned to screw the plug in the opposite
direction and open the thimble the air passage or vent will be open through
the bush.
I attain the fourth and fifth objects of my said invention as follows:-In the
upper part of the said apparatus and near the coin slit I provide a lever which
when the cask is empty engages under the plate which is described in the Specifi-
cation of my prior Letters Patent No. 20083 of A.D. 1894 for closing the money
slit to prevent the extraction of coins therefrom. When the said lever thus
engages under the said plate, the latter cannot be depressed by the coin and
consequently the coin cannot be inserted in the money slit. The mechanism for
causing the said lever to engage under the said plate when the cask is empty
consists of a toothed wheel which is operated through a lever or other means from
the measuring tap spindle so as to be turned through an equal space every time
the tap spindle is turned to withdraw a measured quantity of the liquid from the
cask. The face of this wheel has a cam on which the lever rests said cam having
a cut away part so that immediately after the last measured quantity of the liquid

page_text: has been withdrawn through the tap from the measuring device the lever falls into
the cut away part of the cam and thus locks the said plate under the coin slit as
above described.
The spindle of the said wheel which actuates the locking lever above described
has or may have an index finger outside the casing which shews on a dial when the
cask is full and when it is empty and also shews how many measured quantities of
the liquid have been withdrawn from the cask and how many remain in the same.
The said toothed wheel is by preference operated through a pinion and a ratchet
wheel the latter being operated by a ratchet lever from a projection on the
measuring tap spindle. There is also a second ratchet to prevent the r tchet wheel
turning back. The said lever which locks the plate of the money slit can be lifted
by a special key so as to release the said plate and allow of the index finger being
set when the cask is full.
Dated this 27th day of July 1895.

Improvements in and connected with Coin Freed Apparatus for
Delivering Measured Quantities of Liquid from a Cask, Jar, or
Bottle.
I, WILLIAM SHERAR, of No. 49, Gladesmore Road, Stamford Hill, London,
in the County of Middlesex, Accountant, 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 has reference to coin freed apparatus of the kind described in the
Specifications of my Letters Patent No. 18380 of A.D. 1893 and 20083 of A.D. 1894
by which apparatus quantities of beer or other liquid may be extracted from a
cask jar or bottle by the insertion of a coin in the said apparatus.
The objects of my present invention are firstly, to so construct the head of the
cask or barrel to which my said apparatus is to be applied as to afford more room
for the coin freed apparatus to be fixed thereto or formed therewith; secondly, to
provide means whereby the tap hole in the end of the cask or barrel can be opened
or closed independently of the coin freed apparatus so as to enable the said
apparatus to be removed from or fixed to the cask or barrel at any time when
required by the brewer or other authorised person; thirdly, to enable the cask to
be vented through the tap hole; fourthly, to provide means for closing the money
slit to prevent the insertion of a coin when the cask bottle or jar is empty and
fifthly, to provide means for indicating the number of measured quantities of liquid
which have been withdrawn from the cask bottle or jar and also indicate when the
cask bottle or jar is full and empty.

internal mechanism of the same; Fig. 17 is a sectional plan of the same and
Figs. 18 and 19 shew parts of the same separately.
The same letters of reference indicate the same or corresponding parts in all the
figs. of the drawings.
To attain the first object of my invention I make (see Figs. 1 and 2) the head A
of the cask or barrel of metal preferably of sheet brass, the periphery a' of the
head being turned outwardly and made of V-section (see Fig. 2) so as to engage
in the groove of the staves B where the usual wooden head fits. As the metal
head A is comparatively very thin I thus attain for the coin freed apparatus an
additional space almost equal to the thickness of the usual wooden head.
My improved metal head A is corrugated as by the ribs a¹ stamped therein so
as to strengthen the same. Or when the head is made of cast metal the same may
be stayed by ribs cast preferably on that side of the head which is towards the
inside of the cask. The metal case containing the coin freed apparatus is fixed to
the metal head by any convenient means; or the metal head may be made in a box
like form so as then to form the casing for the coin freed apparatus and the
measuring compartment for the same.
This
According to one method of carrying out the second part of my invention (see
Figs. 3, 4, 5, 6, 7, 8 and 9) I provide a metal thimble C, shewn separately by
Fig. 8, which is fixed in the tap hole in the head A of the cask or barrel as by
screws passing through the front flange c¹ of the thimble into the head A of the
cask or barrel. Free to turn in this thimble C there is a tubular bush D shewn
separately by Fig. 9 provided with a flange d' on the outside of the thimble C
which is by preference made with spur teeth cut in its periphery so that it can be
turned by the pinion like key G from the outside of the cask or barrel.
flange d' is by preference made separate from the bush D and fixed thereto as
shewn. This bush D is screw threaded inside at d and at its inner end is provided
with a metal plug E, shewn separately by Fig. 7, which is also screw threaded
at e on the outside and can turn freely in the bush D and is made with a flange e²
or otherwise formed at its inner end so as to close the end of the plug D when
screwed up tightly against the inner end of the thimble C as shewn in Fig. 4.
The spigot f of the measuring tap F of the coin freed apparatus is screw threaded
so as to fit into the bush D and the end 2 of this spigot is provided with a square
projection or is otherwise formed so as to engage in a corresponding hole e³ in the
plug E and turn the same as hereinafter described. There are side grooves or
passages in the plug E through which when the plug is screwed outwardly from
the bush D as shewn in Fig. 3 and as hereinafter described, the liquid can flow
from the cask through the plug E and spigot to the tap F of the measuring
device.
I will
The above described tap hole closing device is operated as follows.
assume that the coin freed apparatus has been removed from the head of the cask
for some purpose and that the tap hole in the bush D is closed by the plug E
screwed tightly against the inner end of the thimble as shewn in Fig. 4. To
attach the coin freed apparatus it is placed in position on the head of the cask the

page_text: projection of the spigot of the measuring tap F entering the bush D and
engaging with the hole or recess in the plug E. The bush D has now to be
turned by the pinion key G engaging with the teeth on the flange d' of the bush
as shewn in Figs. 3 and 5. This has the effect of drawing the spigot f¹ into the
bush D and screwing the plug E out of the same until ultimately the flange d¹ of
the bush will bear against the washer f³ on the case of the coin freed apparatus H
and prevent leakage. The parts will now occupy the positions shewn by Fig. 3
and the liquid will be free to flow from the cask or barrel through the channels e*
in the plug E and through the bush D and tap F into the measuring device.
Before the coin freed apparatus H can be removed from the head of the cask or
barrel the bush D has to be turned by the pinion key G in the opposite direction
to that above described, so as to screw the plug E back into the bush D and close
the tap hole F and at the same time screw the spigot end f¹ of the tap out of
the bush.
In the above described arrangement of the second part of my present invention
the tap F is immediately in front of the thimble C and bush Ď in the cask, but
in the modification of this part of my invention which is illustrated in sectional
plan by Fig. 10, and in part elevation by Fig. 11, I arrange the tap F at one side
of the thimble C when viewed from the front of the cask and I arrange a screwed
spigot f¹ in a screw threaded hole f* through the solid metai of the casing H of
the apparatus so that the spigot fl of the plug E can be turned from the front of
the apparatus without the use of the toothed flange d'and the pinion key. In this
case the liquid after passing through the passages et in the plug E, flows out of a
side hole in the spigot F and into a cavity or passage h' leading to the tap F by
which the inlet and outlet from the measuring chamber are controlled.
I may, as shewn in Fig. 12, provide a somewhat similar arrangement of thimble
and plug for closing the vent hole into the cask, arranged at one side of the tap
hole which regulates the air inlets into the cask and into the measure as described
in the Specification of my prior Letters Patent No. 20,083 of A.D. 1894 so as to
be operated by a screw driver or other means from the front of the apparatus and
enable the vent passage into the cask or barrel to be opened after the apparatus
has been fixed to the cask, or closed immediately before the apparatus is removed
from the cask thus preventing any waste of the contents through the vent hole.
C is the thimble fixed to the head of the cask and E is the plug screwed into the
inner end of the thimble. f¹ is a spigot which is carried in the chamber H of the
coin freed apparatus and is made with an internal passage f leading to said
chamber and is also made at its front end with a square or other spigot end f² to
connect with the plug E so that when the front cover of the casing of the coin
freed apparatus has been removed the spigot f₁ can by a screw driver be screwed
forward moving the plug E with it and closing the vent and allowing of the coin
freed apparatus to be removed. Or the spigot f¹ can be screwed in the opposite
direction to screw out the plug E as shewn in Fig. 12.
To attain the third object of my invention I provide as shewn in Fig. 13 a
passage i in the casing of the apparatus leading from the bush in the tap hole to
the air inlet or vent which is controlled by the tap F as described in the
Specification of my said prior Letters Patent so that when the bush D is turned to
screw the plug E into the thimble C and close the tap hole as above described the
vent will be closed also to prevent the escape of liquid from the barrel and when
the bush D is turned to screw the plug in the opposite direction and open the
thimble the air passage or vent will be open through the bush D.
I attain the fourth and fifth objects of my said invention as follows (see Figs. 14,
15, 16, 17, 18 and 19). In the upper part of the coin freed apparatus and near the
coin slit provide a lever K fulcrumed at k¹ which lever when the cask is empty
engages under one of the tails of the plate S which is described in the
Specification of my prior Letters Patent No. 20,083 of A.D. 1894 for closing the
money slit to prevent the extraction of coins therefrom. When the lever K thus

page_text: engages with the plate as shewn in Fig. 16 the latter cannot be depressed by cue
coin and consequently the coin cannot be inserted in the money slit.
The mechanism for causing the lever K to engage with the plate S when the
cask is empty as above described, consists of the toothed wheel L shewn separately
by Fig. 19 which is operated from the measuring tap spindle by any convenient
means so as to be turned through an equal space every time the tap spindle is
turned to withdraw a measured quantity from the cask. The mechanism which
I prefer to employ for operating the tooth wheel L as aforesaid is shewn on my
drawings and consists of a toothed pinion m' engaging with the toothed wheel L
and carrying the ratchet wheel m² which is operated by the spring ratchet m³
carried with the lever m¹ which engages with the arm m³ fixed on the measuring
tap spindle so that when the measuring tap spindle is turned through the proper
angle to open the measuring tap the movement of the arm m will pull the lever or
rod m* and move the ratchet wheel m³ through one tooth and proportionately move
the toothed wheel L. A click m (see Fig. 17) engages with the teeth of the
ratchet wheel m² preventing the same moving backwardly. The face of the
wheel L has a cam non which a projecting part 3 of the lever K rests (see
Fig. 1) when there is liquid in the cask and the money slit j is to open this cam n
has a cut away part n¹ by which immediately after the last measured quantity of
liquid has been withdrawn through the tap of the measuring device, the lever K
falls into the cut away part n' of the cam n and thus the other end 2 of the lever
engages with the plate S and thus locks the said plate under the coin slit as shewn
in Fig. 16 as above described.
The spindle o of the wheel L which actuates the locking lever above described,
has or may have an index finger P outside the casing of the coin freed apparatus
which as shewn in Fig. 14 shews on a dial when the cask is filled and when it is
empty and also shews how many measured quantities of liquid have been withdrawn
from the cask and how many remain in the same. The position of the finger
(shewn in Fig. 14) indicates on the dial that there are eighteen glasses or other of
the measured quantities remaining in the cask before it is empty. The lever K
which locks the plate S of the money slit may if desired be arranged to be lifted
by a special key so as to release the plate S and also allow of the index finger P
being set properly when the cask is full. The said key for raising the lever K
may be inserted through a hole r (see Fig. 16).in which case the hole is closed by
a locked cover or by other means.
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 :-
