PROVISIONAL SPECIFICATION.
Improvements in Taps for Automatically Indicating and Measuring
Fluids.
We, JOHN EDWIN GUNN, of Wostgate Chambers, Westgate Street, Cardiff,
Accountant, and FRANCIS GWYN GRIFFITH, of Llansannar House, Cowbridge,
Gentleman, both in the County of Glamorgan, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in apparatus for automatically measuring
liquids as they aro drawn from the bulk, indicating the quantity and value drawn, as
well as the level of the liquid in bulk.
In carrying it into offect, we provide a suitable tap, the plug-way of which is hent
at an anglo, so as to establish a communication between the liquid in bulk or the
glass into which it is to be drawn and a monsnro fixed, preferably above the tap.
The measure is furnished with a tube for the escape of the air therefrom, and this
tube may be long enough to serve as a level gauge.
Tho tap handle is connected by any suitablo mechanism with an index, which it is
adapted by the said mechanism to move over one division of a scale, each time that
the handle is turned. A scale of values may be added.
Each time that the indox reaches a certain point, or returns to zero, one of a
number of small balls, or discs, is released from a receptacle, and allowed to fall into
a second one.
Suitable provisions are made for safe-guarding the indicating parts of the
apparatus from being tampered with.

COMPLETE SPECIFICATION.
Improvements in Taps for Automatically Indicating and Measuring
Fluids.
We, JOHN EDWIN GUNN, of Westgate Chambers, Westgate Street, Cardiff,
Accountant, and FRANCIS GWYN GRIFFITH, of Llansannar House, Cowbridge,
Gentleman, both in the County of Glamorgan, 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 :-
Our invention relates to improvements in apparatus for automatically measuring
liquids as they are drawn from the bulk, indicating the quantity and value drawn,
as well as the level of the liquid in bulk.
In carrying it into effect, we provide a suitable tap, the plug-way of which is bent
at an angle, so as to establish a communication between the liquid in bulk, or the
glass in which it is to be drawn, and a measure fixed, preferably, above the tap.
The measure is furnished with a tube for the escape of the air therefrom, and this
tube may be long enough to serve as a level-gauge.
The tap-handle is connected by any suitable mechanism with an index, which is
adapted by the said mechanism to move over one division of a scale each time that
the handle is turned. A scale of values may be added.
Each time that the index reaches a certain point, or returns to zero, one of a
number of small balls, or discs, is released from a receptacle, and allowed to fall into
a second one.

page_text: Suitable provisions are made for safe-guarding the indicating parts of the
apparatus from being tampered with.
In order that our said invention, and the means by which the same is to be carried
into practical effect, may be thoroughly understood, we will now proceed to describe
them in detail, referring in so doing to the accompanying drawings, which are to be
taken as part of this specification and read therewith.
bi in side aluation
Fig. 9 is a sectional rear elevation.
Fig. 10 is a detail.
Referring to Figs. 1, 2 and 3, A is the bore of the tap, and a the plug. The
way of the latter opens out to the periphery of the plug by two ports b, c, placed at
the same angle with each other as are the axes of the tap-bore and the measuring
vessel respectively, so that when one is in communication with the bore of the tap
the other is open to the measure ('. According to the relative position of the parts
illustrated, which is the most natural and convenient, the cock-plug will move
through a quarter of a circle. (is the measure fixed to the cock-barrel; and C³, a
pipe fed away from the top of the measure in a vertical direction for a sufficient
height, thereby being adapted to discharge the functions of both an air-pipe and a
level-guage. D is the indicator supported at a suitable height. Its dial d may be
provided with any suitable scale d', each division indicating one charge and discharge
of the mensuring vessel, ie., one sale of a quantum of liquor. The small scale d' is
a scale of values, and may be sot out with reference to the scale of quantities, so
that when quantities to the value of, say £1, have been drawn, the index shall
move over one division of the scale. In Fig. 3, the scalo d' is divided into 24, and
the scaled into 12, divisions. Supposing that a turn of the cock passes threepenny-
worth, then each motion of the index will indicate the passage into the measure
of six shillings-worth of liquor. The mechanism connecting the two indices is of any
suitable type adapted to effect their relative action as above described.
The large index d' is moved through one division of its scale by a link e pivotted
to the indicator mechanism and to a lever e¹ on the cock-plug. The indicator
mechanism is contained within the case of the indicator, and is of any suitable type
adapted to move the index d over one division of the scaled for each time the
cock-plug is turned, and to leave the index stationary each time the cock-plug is
turned back.
The operation of my invention constructed as above described is as follows. When
it is required to draw a quantum of liquor, the cock-plug is turned so as to bring
the ports b, c, into the position illustrated in Fig. 2, whereupon the liquor flows into
the measure C. The cock is then reversed, thereby shutting off the supply from the
measure C, and opening the latter to the customer's glass.
Referring to Figs. 4 and 5, the indicator is fixed to the sido of the cock and
measure, and is operated directly from the plug of the latter without the intervention
of the link e and lover e'.
Referring to Figs. 6 to 10, the value-indicator described with reference to Figs. 1
to 8 is replaced by the one noxt described.
Fis a jar adapted to contain a supply of balls f. G is a tube loading from the
jur into a suitable lock-up receptacle It (represented as a glass tabo), in which they
may Le easily counted, and from which they can be removed. The capacity of the
receptacle is equal to that of the jar F and tube G. The locking device illustrated
consists of a plug H and a tab h. The latter has a hole formed in it by which the
said tab can be locked to one or more fixed staples, 2, by a padlock, when the plug

page_text: is in the position illustrated. It will be observed that the top of the plug forms the
bottom of the receptacle, so that none of the balls drop out of sight.
The tube G is controlled by a pair of valves i, j, adapted to pass only one ball at
a time.
-
The mechanism for operating the valves is as follows:-
K is a cam upon the axis of the index d'; and k, its projection. L is a bell
crank pivotted at 1, its short arm adapted to be engaged by the projection k once in
each revolution. M is a link connecting the valves i, j, to the long arm of the bell
crank. Qis a spring adapted to return the link after its depression by the cam.
The operation of this part of our invention is as follows. As the index is com-
pleting one revolution, it engages the projection k, and thereby moves the valve i
from before the balls, the botton one, n, falling against the second valve j. The
projection k is next released, when the spring Q draws the valvej from before the
ball n, which thereupon drops into the receptacle, but the said spring stops the next
ball n by pulling the valve in front of it. The entrance of each ball into the
receptacle will therefore register the sale of liquor to a value corresponding with the
number of times the cock plug is operated during one revolution of the index d'.
We do not confine ourselves to the number of projections upon the cam. The use of
one only, as illustrated, provides for the value represented by one revolution of the
index d being indicated. If it is desired to take indications every half-revolution,
the number of projections must be doubled, and so on. Discs may be substituted for
balls if desired.
When it is desired to work a number of cocks through which identical values are
drawn, they may all be connected to one indicator by suitable link mechanism.
Suitable devices are provided for preventing the indicating mechanism from
being tampered with; and also the cock plugs from being turned in the wrong
direction.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of cock-plug having an angular way adapted to alternately
deliver from the supply into a measure, and from the measure into the glass, an
indicator provided with quantity and valve indices and scales, and link and lever
mechanism adapted to transfer the motion of the cock-plug to the said indicator, as
set forth.
2. The combination of cock-plug and quantity and value indices the former actuated
direct by the plug as set forth.
3. The combination of cock plug, quantity index, and a ball, tube, and valve
mechanism operated from the said plug as set forth.
