PROVISIONAL SPECIFICATION.
A New or Improved Measuring Tap or Device for Drawing off Given
Quantities of Liquid from Urns or other Vessels.
We, HENRY STODDARD BISHOP, of 19, Friday Road, Engineer, and ROBERT
BURN, of The Prince of Wales Hotel, Licensed Victualler, both in Erith, in
the County of Kent, do hereby declare the nature of this invention to be as
follows:-
The invention relates to a new or improved measuring tap or device for
drawing off given quantities of liquid from urns or other vessels, and the
primary object of the invention is to obtain a simple and inexpensive contriv-
ance by the aid of which given quantities of the liquid contents of the vessel
may at the will of the operator be drawn off and accurately measured or run
through the device without measuring.
In carrying the invention into effect a measuring chamber is employed con
sisting preferably of a cylinder of glass which at its ends is received into caps
fitted with discs of cork rings of india-rubber or other suitable packing con-
trivances and these caps are at intervals around their periphery formed with
lugs perforated to receive rods or bolts and these bolts are at one end fixed with
one of the caps whilst at the other end they are threaded and pass through the
lugs of the other cap and are there furnished with nuts by means of which the
two caps are forced together and a tight joint thus made between the caps and
the ends of the glass cylinder.
The upper cap has fixed thereto and communicating therewith a cock or tap
of ordinary construction which is fed by a pipe or barrel adapted to enter
through the tap or other hole of the vessel from which the liquid is to be drawn
and the lower cap has fixed therewith and communicating with the interior of
the measuring chamber a cock or tap which terminates in a delivery spout.
The supply tube or barrel of the upper tap at its junction with the barrel of
the tap is furnished with a flange adapted to form a seat for a ring of india-
rubber, cork, or other suitable packing material which is intended to bear
against the exterior of the vessel to which the tap or measuring device is to
be fixed around the tap hole thereof whilst upon the supply pipe or barrel is
oosely fitted a washer which is similarly designed to take a bearing upon the
nside of the vessel and the end of the pipe or barrel is threaded to receive a
ut by the aid of which the flange and washer may be forced together and a per-
ectly tight joint made between the parts.
The plugs of both the upper and lower cocks or taps are furnished with cranks
which are coupled by means of a connecting rod hereinafter more fully described
nd the crank of the lower tap is furnished with a projecting lever or thumb
iece by means of which the taps may be actuated whilst the faces of said cranks
re provided with projecting studs which come against the connecting rod and
ct as stops to arrest the plugs in either of their extreme positions.
The cranks of the plugs of the cocks are so arranged and coupled
1

page_text: connecting rod that when one of the cocks or taps is open the other is closed,
that is to say they are never open or partly open at the same time.
In order to allow of the escape of the air contained in the measuring chamber
during the inflow of the fluid from the vessel a vent or escape pipe is employed
which passes through the upper cap and through the supply tube or barrel to
a position above the level of the liquid in the vessel to which the device is
fixed.
By the arrangement of parts hereinbefore described the contents of the vessel
may be drawn off in given quantities until the supply is exhausted.
In order however to enable the measuring device to be thrown out of action
and the instrument when desired employed as an ordinary cock or tap the con-
necting rod coupling the cranks is at its lower end formed with an open ended
slot in which the pin of one of the cranks works and upon this pin is pivotally
mounted a hook or catch adapted at the times desired to engage a headed stud
carried by the connecting rod thus locking the parts to-gether.
or
By means of this device when the lower crank pin is coupled with the con-
or catch the plugs of the cocks or
necting rod by means of the hook
UB to work in unison, whilst by turn-
taps will also be coupled so
ing back the hook catch and disconnecting the crank pin from
the connecting rod said crank pin will upon the movement of the actuating
lever or handle simply be moved to and fro in the slot of the connecting rod
without imparting any movement to the plug of the upper cock except that the
disconnection be made in the lower position of the cranks that is when the
lower cock is open and the upper one closed in which case the next upward
movement of the crank pin will simply carry the connecting rod to the upper
end of its traverse where it will remain consequently leaving the upper cock
open until the parts are again connected.
It will be understood that the device by modifying the means of connection
may be attached to the bib of a tap or in other desired situation.
It will be obvious that the details of the device may be more or less varied
without departing from the principle of the invention.
By the means herein before described a simple, inexpensive and extremely
serviceable form of measuring device is obtained particularly adapted for use
in refreshment houses, inasmuch as in the event of a large quantity of liqui
being required to be drawn the measuring appliance may be readily uncoupled
and the liquid contents of the vessel simply run through into an open measure
in the ordinary way.
A New or Improved Measuring Tap or Device for Drawing on Given
Quantities of Liquid from Urns or other Vessels.
We, HENRY STODDARD BISHOP, formerly of 19, Friday Road, Erith, in the
County of Kent, but at present residing at Thurlow Lodge, Norwood Road,
in the County of Surrey, Engineer, and ROBERT BURN, of The Prince of Wales
Hotel, Erith, in the County of Kent, Licensed Victualler, 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:-
The invention relates to a new or improved measuring tap or device for

page_text: drawing off given quantities of liquid from urns or other vessels, and the
primary object of the invention is to obtain a simple and inexpensive contriv-
ance by the aid of which given quantities of the liquid contents of the vessel
may at the will of the operator be drawn off and accurately measured or run
through the device without measuring.
In carrying the invention into effect a measuring chamber is employed con-
sisting preferably of a cylinder of glass which at its ends is received into caps
fitted with discs of cork, rings of india-rubber or other suitable packing con-
trivances and these caps are at intervals around their periphery formed with
lugs perforated to receive rods or bolts and these bolts are at one end fixed with
one of the caps whilst at the other end they are threaded and pass through the
lugs of the other cap and are there furnished with nuts by means of which the
two caps are forced together and a tight joint thus made between the caps and
the ends of the glass cylinder.
The upper cap has fixed thereto and communicating therethrough a cock or tap
of ordinary construction which is fed by a pipe or barrel adapted to enter
through the tap or other hole of the vessel from which the liquid is to be drawn
and the lower cap has fixed therewith and communicating with the interior of
the measuring chamber a cock or tap which terminates in a delivery spout.
The supply tube of the upper tap at its junction with the barrel of
the tap is furnished with a flange adapted to form a seat for a ring of india-
rubber, cork, or other suitable packing material which is intended to bear
against the exterior of the vessel to which the tap or measuring device is to
be fixed around the tap hole thereof whilst upon the supply pipe or barrel is
loosely fitted a washer which is similarly designed to take a bearing upon the
inside of the vessel and the end of the pipe or barrel is threaded to receive a
mut by the aid of which the flange and washer may be forced the one toward
the other and a perfectly tight joint made between the parts.
The plugs of both the upper and lower cocks or taps are furnished with cranks
which are coupled by means of a connecting rod hereinafter more fully described
and the crank of the lower tap is furnished with a projecting lever or thumb
piece by means of which the taps may be actuated whilst the faces of said cranks
are provided with projecting studs which come against the connecting rod and
act as stops to arrest the plugs in either of their extreme positions.
The cranks of the plugs of the cocks are so arranged and coupled by the
connecting rod that when one of the cocks or taps is open the other is closed,
that is to say they are never open or partly open at the same time.
In order to allow of the escape of the air contained in the measuring chamber
during the inflow of the fluid from the vessel a vent or escape pipe is employed
which passes through the upper cap and through the supply tube or barrel to
a position above the level of the liquid in the vessel to which the device is
fixed.
By the arrangement of parts hereinbefore described the contents of the vessel
may be drawn off in given quantities until the supply is exhausted.
In order however to enable the measuring device to be thrown out of action
and the instrument when desired employed as an ordinary cock or tap the con-
necting rod coupling the cranks is at its lower end formed with an open ended
slot in which the pin of one of the cranks works and upon this pin is pivotally
mounted a hook or catch adapted at the times desired to engage a headed stud
carried by the connecting rod thus locking the parts together.
..
By means of this device when the lower crank pin is coupled with the con-
necting rod by means of the hook or catch the plugs of the cocks or
taps will also be coupled so as to work in unison, whilst by turn-
ing back the hook or catch and disconnecting the crank pin from
the connecting rod said crank pin will upon the movement of the actuating
lever or handle simply be moved to and fro in the slot of the connecting rod
without imparting any movement to the plug. of the upper cock except that the

page_text: the tap may be actuated whilst the faces of said cranks are provided with pro-
jecting studs e³ ³ which come against the connecting rod 7 and act as stops
to arrest the plugs ef in their extreme or open positions.
The cranks 1 of the plugs ef of the cocks are so arranged and coupled
by the connecting rod g that when one of said cocks or taps is open the other is
closed; that is to say they are never open or partly open at the same time.
In order to allow of the escape of the air contained in the measuring chamber a
during the inflow of the fluid from the vessel or reservoir and to supply air
during the outflow of said fluid a vent or escape pipe is employed which passes
through the upper cap al and through the supply tube c beyond which it is
by an india-rubber junction coupled with a glass or other tube which
extends to a position above the level of the liquid within the vessel or reser-
voir to which the device is fixed as shown at Figure 1 but if desired the vent
pipe might be carried up outside the urn as will be readily understood.
By the arrangement of parts herein before described in the raised or normal
position of the thumb-lever f the upper cock c will be open the lower cock d
will be closed and liquid will flow from the vessel or reservoir into the
measuring chamber a until the same is filled whilst upon depressing said thumb-
lever the upper cock c will be first closed thereby closing the communication
with the vessel . and the lower cock d afterwards opened thereby permitting
the contents of the measuring chamber a to flow out by the spout d' into a glass
or drinking vessel held beneath the same after which by raising the thumb-
lever the lower cock & will be first closed and the upper cock c afterwards
opened when the measuring chamber a will be again filled with liquid and by
repeating these operations the contents of the vessel or reservoir .r may be drawn
off in given quantities until the supply is exhausted.
In order however to enable the measuring device to be thrown out of action
and the instrument when desired employed as an ordinary cock or tap the con-
necting rod a coupling the cranks el f¹ is at its lower end formed with an open
ended slot g¹ in which the pin of the crank fl works and upon said pin is
pivotally mounted a hook or catch h adapted at the times desired to engage a
headed stud g carried by the connecting rod g thus locking the crank pin f
with said connecting rod.
By means of this device when the lower crank pin f is coupled with the con-
necting rod g by means of the hook or catch h the plugs ef of the cocks or taps
will also be coupled so as to work in unison upon the movement of the thumb
lever whilst by turning back the hook or catch h and thereby disconnecting
the crank pin f2 from the connecting rod g said crank pin will upon the move-
ment of the actuating lever or handle simply be moved to and fro in the
slot g without imparting any movement to the plug e of the upper cock c
except that the disconnection be made in the lower position of the cranks that
is to say when the upper cock c is closed and the lower cock d is open, in which
case the next upward movement of the actuating lever f and crank pin f will
simply carry the connecting rod g to the end of its upward traverse where it will
remain consequently leaving the upper cock c open until the parts are again
connected by the hook h.
Any suitable device other than that hereinbefore described may be employed
for coupling at will the crank pin and connecting rod g.
It will be understood that the device by modifying the means of connection of
the supply pipe c¹ may be attached to the bib of a tap or in other desired
situation.
It will be obvious that the details of the device may be otherwise more or less
varied without departing from the principle of the invention.
By the means herein before described a simple inexpensive and extremely
serviceable form of measuring device is obtained which is particularly adapted
for use in refreshment houses, inasmuch as in the event of a large quantity of
liquid being required to be drawn, the measuring appliance may be readily

page_text: uncoupled and the liquid contents of the vessel or reservoir simply run through
the apparatus into an open measure in the ordinary way.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. A measuring device adapted to be connected with a reservoir of liquid and
comprising a measuring chamber, a cock controlling the inflow of liquid to
said chamber, a cock controlling the outflow of liquid therefrom, an air vent from
