PROVISIONAL SPECIFICATION.
A New or Improved Tap or Device for Drawing Off Given
Quantities of Liquid from Bottles or other Vessels.
We, HENRY STODDARD BISHOP, of Englewood, Belvedere Park, 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 tap or device for drawing off given
quantities of liquid from bottles or other vessels and has for its object to obtain a
simple and inexpensive contrivance which may be readily applied to a bottle or the
like, and by the aid of which the contents thereof may be readily drawn off and
measured in given quantities without exposing the liquid to the atmosphere.
In carrying the invention into effect the tap is formed with a tube or barrel, upon
which is fixed a disc provided with an annular groove or recess in which is placed a
ring of rubber or other suitable packing, whilst upon the inner end of the tube or
barrel is slidden an outer tube carrying a similar disc and between these discs is
placed a cylinder of glass, and these parts which constitute the measuring chamber
are forced together so as to make a tight joint by means of a thumb screw which
passes through a plain hole in the end of the outer tube and engages a corresponding
nut fixed in the end of the tube or barrel, and upon the outer tube and at the
back of the dise carried thereby is fixed a cork adapted to fit into an ordinary bottle-
or decanter.
The inner end of the tube or barrel is provided with a way or opening which
communicates with the contents of the vessel in which the tap is placed, and the
outer tube is correspondingly perforated to allow of the passage of the liquid into the
barrel through such opening, whilst that part of the barrel within the measuring chamber
is perforated to allow the liquid to flow from the barrel into the measuring
chamber, and in order to provide for the necessary escape of air from the measuring
chamber during this operation a small air tube is carried by the outer tube in such
manner that it passes through the cork whilst one end communicates with the
interior of the vessel from which the liquid is to be drawn, and the other end
communicates with a perforation in the inner disc and consequently with the
measuring chamber.
In order to normally close the outer end of the barrel and to enable the liquid to
be drawn off from the measuring chamber at the times desired the tube or barrel is
provided with an inner tube or valve which closely fits the same but slides nicely
therein, and this inner tube extends to the inner end of the barrel where it is closed,
whilst beyond that point is arranged a helical or other suitable spring, which normally
forces the inner tube forward.
The inner sliding tube is perforated in such manner that it is always open to the
perforations in the inner end of the barrel and outer tube, and thus is always open
to the liquid in the bottle or other vessel, whilst it is also perforated in such manner
that when in its outer or closed position a perforation corresponds with the way in

page_text: the barrel leading into the measuring chamber whilst immediately beyond such
perforation it is stopped, and beyond such stop it is formed with anothe. perforation
adapted when the sliding tube is in its inner position to register with the perforation
of the barrel within the measuring chamber, so that by pressing the inner tube
inward the supply will be cut off from the bottle or other vessel to the measuring
chamber, and the contents of the latter will be placed in communication with the
outer end of the inner tube which terminates in a nozzle or bib.
In order to furnish the necessary supply of air to the measuring chamber to enable
the contents to be drawn off therefrom, at the inner end of the measuring chamber
the tube or barrel is formed with a small air way or perforation and the inner sliding
tube is provided with a corresponding perforation which in the inner position of the
sliding tube registers therewith, and this perforation communicates with an air
conduit arranged on the interior of the sliding tube and opening in a convenient
position to the outer air.
The inner sliding tube beneath the nozzle or bib is provided with a claw or pro-
jection adapted to engage the edge of a glass or other vessel and facilitate the press-
ing inward of the inner sliding tube and consequent opening of the way from the
measuring chamber.
In order to draw off a measured quantity of liquid from a bottle or other vessel
fitted with a tap or device of the character herein before described, it will merely be
necessary to rest the claw of the nozzle or bib upon the edge of the glass or other
vessel into which a measured quantity of liquid is to be drawn, and incline or invert
the bottle or vessel when the measuring chamber will immediately fill and by de-
pressing the bottle or vessel so as to force inward the inner sliding tube the contents
of the measuring chamber will at once flow through the nozzle or bib into the glass
or the like.
The device herein before described is simple and inexpensive to produce, whilst it
possesses the great advantage that the contents of the vessel are never open to the
atmosphere during the measuring operation or in any position of the parts, and this
is especially valuable when dealing with volatile liquids as will be readily under-
stood.

A New or Improved Tap or Device for Drawing off Given
Quantities of Liquid from Bottles or other Vessels.
We, HENRY STODDARD BISHOP, of Englewood, Belvedere Park, 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 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 tap or device for drawing off given
quantities of liquid from bottles or other vessels and has for its object to obtain a
simple and inexpensive contrivance which may be readily applied to a bottle or the
like and by the aid of which the contents thereof may be readily drawn off and
measured in given quantities without exposing the liquid to the atmosphere.
In carrying the invention into effect the tap is formed with a tube or barrel upon
which is fixed a dise provided with an annular groove or recess in which is placed a

page_text: ring of rubber or other suitable packing whilst upon the inner end of the tube or
barrel is slidden an outer tube carrying a similar disc and between these discs is
placed a cylinder of glass, and these parts which constitute the measuring chamber
are forced together so as to make a tight joint by means of a thumb screw which
passes through a plain hole in the end of the outer tube and engages a corresponding
nut fixed in the end of the tube or barrel, and upon the outer tube and at the back
of the disc carried thereby is fixed a cork adapted to fit into an ordinary bottle or
decanter.
The inner end of the tube or barrel is provided with a way or opening which com-
municates with the contents of the vessel in which the tap is placed and the outer
tube is correspondingly perforated to allow of the passage of the liquid into the
barrel through such opening whilst that part of the barrel within the measuring
chamber is perforated to allow the liquid to flow from the barrel into the measuring
chamber and in order to provide for the necessary escape of air from the
measuring chamber during this operation a small air tube is carried by the outer
tube in such manner that it passes through the cork whilst one end communicates
with the interior of the vessel from which the liquid is to be drawn, and the other
end communicates with a perforation in the inner disc and consequently with the
measuring chamber.
In order to normally close the outer end of the barrel and to enable the liquid to
be drawn off from the measuring chamber at the times desired the tube or barrel is
provided with an inner tube or valve which closely fits the same but slides nicely
therein and this inner tube extends to the inner end of the barrel where it is closed
whilst beyond that point is arranged a helical or other suitable spring, which normally
forces the inner tube forward.
The inner sliding tube is perforated in such inanner that it is always open to the
perforations in the inner ends of the barrel and outer tube, and thus is always open
to the liquid in the bottle or other vessel, whilst it is also perforated in such manner
that when in its outer or closed position a perforation corresponds with the way in
the barrel leading into the measuring chamber whilst immediately beyond such
perforation it stopped and beyond such stop it is formed with another perforation
adapted when the sliding tube is in its inner position to register with the perforation
of the barrel within the measuring chamber, so that by pressing the inner tube
inward the supply will be cut off from the bottle or other vessel to the measuring
chamber, and the contents of the latter will be placed in communication with the
outer end of the inner tube which terminates in a nozzle or bib.
In order to furnish the necessary supply of air to the measuring chamber to enable
the contents to be drawn off therefrom, at the inner end of the ineasuring chamber
the tube or barrel is formed with a small air way or perforation and the inner
sliding tube is provided with a corresponding perforation which in the inner
position of the sliding tube registers therewith, and this perforation communicates
with an air conduit arranged on the interior of the sliding tube and opening in a
convenient position to the outer air.
The inner sliding tube beneath the nozzle or bib is provided with a claw or
projection adapted to engage the edge of a glass or other vessel and facilitate the
pressing inward of the inner sliding tube and consequent opening of the way from
the measuring chamber.
In order to draw off a measured quantity of liquid from a bottle or other vessel
fitted with a tap or device of the character herein before described, it will merely be
necessary to rest the claw of the nozzle or bib upon the edge of the glass or other
vessel into which a measured quantity of liquid is to be drawn and incline or invert
the bottle or vessel when the measuring chamber will immediately fill and by
depressing the bottle or vessel so as to force inward the inner sliding tube the
contents of the measuring chamber will at once flow through the nozzle or bib into
the glass or the like.
And in order that the said invention may be more clearly understood and readily

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of a tap constructed according to the present
invention and showing in dotted lines the neck of a decanter in connection
therewith.
Figure 2 is a plan thereof but with the dotted part omitted.
Figure 3 is a horizontal section taken on the line 1-1 of Figure 1.
Figure 4 is a vertical section of the tap showing the same in its closed or normal
position.
and
Figure 5 is a similar view but showing the tap in its open or depressed position,
Figure 6 is a view representing a measured quantity of liquid being drawn from
a decanter fitted with a tap constructed according to the present invention.
In the several figures in which like parts are indicated by similar letters of
reference Figures 4 and 5 are drawn to an increased scale whilst Figure 6 is drawn
to a reduced scale with respect to Figures 1, 2, and 3.
a represents the tube or barrel upon which is fixed a dise a provided with a
flange a forming a groove or recess within which is placed a ring of rubber or other
suitable packing d* whilst upon the inner end of the tube or barrel a is slidden an
outer tube b carrying a similar disc b¹ fitted with a flange 62 and packing ring d*
and between these discs is placed a cylinder d of glass.
These parts which constitute the measuring chamber are forced together so as to
make a tight joint by means of a thumb screw e the threaded stem e¹ of which
passes through a plain hole 63 in the plugged end of the outer tube b and
engages a corresponding nut a³ fixed in the end of the tube or barrel a.
Upon the outer tube 6 and at the back of the disc b¹ carried thereby is fixed
a tapered cork b* adapted to fit into an ordinary bottle or decanter as represented
by the dotted lines in Figure 1 and by the full lines in Figure 6.
The inner end of the tube or barrel a is provided with a way or opening at
which communicates with the contents of the vessel in which the tap is placed
and the outer tube b is correspondingly perforated at 64 to allow of the passage
of the liquid into the barrel a through the opening at whilst that part of the
tube or barrel a within the measuring chamber d is perforated at a³ to allow the
liquid to flow from the tube or barrel a into the measuring chamber d.
In order to provide for the necessary escape of air from the measuring chamber d
during this operation a small air tube 65 is provided which is carried by the outer
tube b and is arranged in such manner that it traverses the cork * whilst one end
thereof enters the interior of the vessel from which the liquid is to be drawn and the
other end communicates with a perforation 61 in the inner disc b¹ consequently with
the measuring chamber d and is made tight with said disc by soldering or
otherwise.
In order to normally close the outer end of the tube or barrel a and to enable the
liquid to be drawn off from the measuring chamber at the times desired the tube or
barrel a is provided with an inner tube or valve c which closely fits the same and
slides nicely therein and this inner tube or valve c extends to near the inner end of
the tube or barrel a where it is closed by means of a plug c¹ whilst beyond that
point is arranged a helical or it might be any other suitable form of spring f which
at one end takes an abutment against the nut a³ of the tube or barrel a and at the
other end acts against the plug c¹ of the inner tube or valve c and this spring f
normally forces the inner tube or valve c forward and closes the tap as hereinafter
explained.
The inner or sliding tube or valve c the movements of which are limited by a
transverse pin a fixed with the tube or barrel a is formed with a long perforation c²
therein so that in any position it is always open to the perforations at 64 in the inner

page_text: ends of the tube or barrel a and outer tube b respectively and thus is always open to
the liquid in the bottle or other vessel in any position of the tube or valve c whilst
said tube or valve c is provided with a perforation which in the outer or closed
position of the tube or valve c corresponds or registers with the way a leading from
the tube or barrel a to the measuring chamber d.
Immediately beyond the perforation c³ the tube or valve c is closed or stopped by
means of a plug or partition ct and beyond the plug c the tube or valve is formed with
another perforation c adapted when the sliding tube or valve c is in its inner position to
register with the perforation as of the tube or barrel a within the measuring chamber d
so that by pressing the inner tube or valve c inward the parts will be caused to assume
the positions shown at Figure 5 when the supply from the bottle or decanter which in
the normal position of the parts is free to pass through the ways a, b, c, tube or
valve cand perforations c³ as to the measuring chamber d will be cut off and the
contents of the measuring chamber will through the perforation of the tube or
barrel a and perforation of the tube or valve c be placed in communication
with the outer end of the inner tube or valve c which terminates in a nozzle or
bib c*.
с
In order to furnish the necessary supply of air to the measuring chamber d to enable
the contents to be drawn off therefrom the tube or barrel a at the inner end of the
measuring chamber c is formed with a small air way or perforation a and the inner
sliding tube or valve c is provided with a corresponding perforation co which in the
inner position of the sliding tube or valve c registers therewith as represented in
Figure 5 and this perforation of communicates with an air conduit c' arranged on the
interior of the sliding tube or valve c and opening to the outer air adjacent to
the bib c✶ or it might open in any other convenient position.
The inner sliding tube or valve c beneath the nozzle or bib c* is provided with a
claw or projection adapted to engage the edge of a glass or other vessel has
represented at Figure 6 or to be acted upon by the finger and facilitate the
pressing inward of the inner sliding tube or valve c and consequent opening of
the way from the measuring chamber d.
In order to draw off a measured quantity of liquid from a bottle decanter or other
vessel such as g fitted with a tap or device of the character hereinbefore described it
will merely be necessary to rest the claw or projection c³ of the nozzle or bib c* upon
the edge of the glass h or other vessel into which a measured quantity of liquid is
to be drawn and incline or invert the decanter or bottle g as represented at Figure 6
when the measuring chamber & will immediately fill and by depressing the decanter
or bottle y so as to force inward the inner sliding tube or valve c the contents of the
measuring chamber & will at once flow through the nozzle or bib c* into the glass / or
other vessel.
The device herein before described is simple and inexpensive to produce whilst it
possesses the great advantage that the contents of the vessel are never open to the
atmosphere during the measuring operation or in any position of the parts and this
is especially valuable when dealing with volatile liquids as will be readily under-
stood.
It will be obvious that instead of forming the measuring chamber of glass or
partly of glass it may be wholly of metal or other suitable material.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A measuring tap comprising a tube or barrel a measuring chamber surrounding
the tube or barrel and made tight therewith, an opening at the lower end of the tube
or barrel to admit thereto the liquid to be measured an opening in said barrel within
the measuring chamber to admit said liquid thereinto, an air conduit from the
measuring chamber to the supply vessel, a tube or valve sliding within the barrel
and normally held in its outward position by means of a spring, a long perforation
in the lower end of said valve placing the same always in communication with the

page_text: supply vessel, an opening in the tube or valve within the measuring chamber said
opening being normally in communication with the corresponding opening of the
barrel, a stop or partition in the tube or valve above said opening and a similar
opening above said stop adapted to register with the opening in the barrel within
the measuring chamber in the depressed position of the valve, an air way through
the barrel within the measuring chamber and an air conduit carried by the valve
and adapted to register with said air way in the depressed position of the valve and
place the same in communication with the outer air substantially as herein shown
and described.
2. A measuring tap comprising a barrel adapted to be placed in communication
with the contents of a vessel to be measured a measuring chamber an opening from
the barrel to the measuring chamber, an air way from the measuring chamber to the
supply vessel, a sliding tubular valve within the barrel at its lower end
open to
the supply vessel and provided with suitable ports so arranged that in the normal
position of the parts the liquid will flow into the measuring chamber whilst in the
other position the measuring chamber will be cut off from the supply vessel and the
contents of the measuring chamber will be drawn off into a glass or other receptacle
and an air conduit in the barrel within the measuring chamber in said position of
the parts placed in communication with the outer air substantially as herein shown
and described.
3. A measuring tap or device for drawing off given quantities of liquid from
