An improved measuring tap.
I, ALICE WOOLLATT, of 27, Millicent Road, West Bridgford, Nottingham,
Gentlewoman, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved measuring tap designed to meet the
requirements of dealers in liquids vended in measured quantities, and consists
of a measuring tap in which the several features hereinafter described are com-
bined in co-operative relation.
The tap is made with a container which is made of such dimensions as are
determined by its required capacity, and is closed at one end and is open and
fitted with a removable cover at the other end, or it may be open and
fitted with a removable cover at each end, to facilitate access to its interior, and is
formed with an inlet for the liquid to be measured, and with an outlet for the
measured liquid. Internally, the container is fitted with a pair of shut-off plates
which are formed with coned peripheries and are secured to and located by a
spindle and are adapted to truly fit in coned seatings formed in the container
ends respectively; or, the plates may be borne against their seatings by a spring.
The plates are also respectively formed with through holes which, respectively,
are equidistant from the axis of the spindle with the liquid inlet and outlet
apertures with which they are adapted to respectively communicate, and are so
located in relation to each other that they cannot both together communicate with
such inlet and outlet apertures, and that they can both together be shut off from
communicating therewith, and that each one can be caused to communicate with
its respective aperture as required, the plates being thus adapted to close the said
inlet and outlet apertures one at a time in such a manner that while the outlet
is closed the inlet may be open so that the liquid can freely flow from a reservoir
into the container, or may be closed, and that while the outlet is open the inlet
is closed.
The upper plate is fitted with a vent tube which opens into the container and
protrudes through a sectoral slot, made in the cover, of such a length as to
accommodate the two extreme positions of the shut-off plates, the tube being thus
caused to serve the two purposes of acting as a vent to the container, (its pro-
jecting part being perforated) permitting of the inflow and outflow of the liquid,
and of determining the two extremes of the movements of the shut-off plates.
The tube serves to locate a valve stem which is fitted with a valve serving to
close the inner end of the tube and with a float which causes the valve to shut
as the container fills with liquid, the float being formed with grooves which engage
with guide pins which project from the upper plate. The outer end of the steni
is fitted with a knob which prevents the valve from falling into the container
when it is emptying and, when the parts are moved into the emptying position,
is adapted to engage with a depressor which depresses the valve from its seating
in the plate and permits of the air entering the container so as to allow of the
unimpeded escape of the liquid therefrom.
The spindle protrudes through the cover and is fitted with a handle by which it

page_text: can be turned about its axis so as to actuate the shut-off plates to the extent
limited by the engagement of the vent tube with the ends of the sectoral slot, aş
aforesaid. The spindle may be connected in any convenient manner to suitable
recording apparatus adapted to be operated at each filling or emptying actuation
of the handle so as to automatically record the total quantity of liquid measured
out.

I, ALICE WOOLLATT, of 27, Millicent Road, West Bridgford, Nottingham,
Gentlewoman, 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 relates to an improved measuring tap designed to meet the
requirements of dealers in liquids vended in measured quantities, and consists
of a measuring tap in which the several features hereinafter described are com-
bined in co-operative relation as described with reference to the accompanying
drawings, in which,
Figure, 1 is a sectional elevation, showing the parts in the positions occupied
when the tap is filling;
Fig. 2, is a sectional plan on AB, Fig. 1, with the cover removed;
Fig. 3, is a sectional plan on CD, Fig. 1;
Fig. 4, is a plan, showing the parts in the positions represented in Fig. 1;
Fig. 5, is an elevation, partly in section, showing the parts in the positions
occupied when the tap is emptying;
Fig. 6, is a sectional plan on E-F, Fig. 5, with the cover removed;
Fig. 7, is a sectional plan on G-H, Fig. 5;
Fig. 8, is a plan, showing the parts in the positions represented in Fig. 5; and
Fig. 9, is a plan, showing the parts in the positions occupied when the tap is
fully charged and is shut off from both the liquid inlet and the liquid outlet;
The same reference letters indicate like parts wherever repeated on the
drawings.
a, is a container which is made of such dimensions as are determined by its
required capacity, and is closed at one end, a¹, and is open and fitted with a
removable cover, b, at the other end, a², or it may be open and fitted with a
removable cover at each end, to facilitate access to its interior, and is formed
with an inlet, c, for the liquid to be measured, and with an outlet, d. for the
measured liquid. Internally, the container is fitted with a pair of shut-off
plates, e, f, which are formed with coned peripheries, c¹, f¹, and are secured to
or located by a spindle, g, and are adapted to truly fit in coned seatings, b¹, a³,
formed in the container ends, b, a¹, respectively, or, the plates, e, f; may be
borne against their seatings by a spring, h. The plates, e, f, are also respectively
formed with through holes, e, f, which, respectively, are equidistant from the
axis of the spindle with the liquid inlet and outlet apertures, c, d, with which they
are adapted to respectively communicate, and are so located in relation to each
other that they cannot both together communicate with such inlet and outlet
apertures, and that they can both together be shut off from communicating there-

page_text: with, and that each one can be caused to communicate with its respective aperture
as required, the plates being thus adapted to close the said inlet and outlet aper-
tures one at a time in such a manner that while the outlet is closed (vide Figs. 1,
to 4,) the inlet may be open so that the liquid can freely flow from a reservoir into
the container, and that while the outlet is open (vide Figs. 5, to 8,) the inlet is
closed, and to close both the said inlet and outlet apertures (vide Fig. 9,) when
the tap is fully charged in readiness to be discharged.
The upper plate, e, is fitted with a vent tube, ?, which opens into the container
and protrudes through a sectoral slot, 62, made in the cover, b, of such a length
as to accommodate the two extreme positions of the shut-off plates (vide Figs. 8,
and 9,) the tube i, being thus caused to serve the two purposes of acting as a
vent to the container, (its projecting part being perforated, as at ¹) permitting
of the inflow and outflow of the liquid to and from the container, and of deter-
mining the two extremes of the movements of the shut-off plates. The tube, i,
serves to support a valve stem, j, which is fitted with a valve, j¹, serving to close
the inner end of the tube and with a float,, which causes the valve to shut as
the container fills with the liquid, the float being formed with grooves, j³, which
engage with guide pins, j, which project from the plate, e. The outer end of the
stem, j, is fitted with a knob, j, which prevents the valve from falling into the
container when it is emptying, and, when the parts are moved into the emptying
position (vide Fig. 5,) is adapted to engage with a depressor, 3, which depresses
the valve, j, from its seating in the plate, e, and permits of the air entering the
container so as to allow of the unimpeded escape of the liquid therefrom.
The spindle, g, protrudes through the cover, b, and is fitted with a handle, g',
by which it can be turned about its axis so as to actuate the shut-off plates to the
extent limited by the engagement of the vent tube, i, with the ends of the
sectoral slot, 2, as aforesaid. The spindle may be connected in any convenient
manner to suitable registering apparatus adapted to be operated at each filling or
emptying actuation of the handle so as to automatically record the total quantity
of liquid measured out.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
In a measuring tap, in combination, a container, a shut-off device and a
vent device respectively adapted as set forth; -the container having a cover
formed with a stuffing-box and a sectoral slot, an inlet and an outlet, and being
formed with conical seatings within its ends;-the shut-off device consisting of
plates located on a common spindle which extends through the stuffing-box of
the cylinder cover and formed with inlet and outlet holes respectively arranged
to communicate with the inlet and outlet of the container, one at a time, and to be
shut off from both together, and with coned peripheries, and of a spring adapted
to press the plates truly against the conical seatings of the container; and the
venting device consisting of a perforated tube fitted to a vent hole in the upper
shut-off plate and of a guided rod, valve and float co-operating to close the air
vent as the container fills with the liquid, and of a depressor fitted to the cover and
adapted to depress the valve from the vent tube when the outlets of the shut-off
plate and of the container communicate, the vent tube and the sectoral slot in the
container cover also co-operating to determine the extremes of the movements of
the shut-off plates, as set forth.
