PROVISIONAL SPECIFICATION.
An Improved Tap or Apparatus for Drawing Off Measured Quantities
of Liquid.
I, RICHARD EDWARD HARRISON, of Anglesea House, London Road,
St. Leonards, in the County of Sussex, Manufacturer, do hereby declare the
nature of this invention to be as follows: --
This invention relates to the construction of a novel and simple apparatus which
can be applied to any ordinary tap or liquid outlet to allow of measured quantities
of liquid being drawn off.
In constructing my improved apparatus I employ a vessel or receiver which will
contain a known quantity or measure of liquid. This vessel is advantageously
made in the form of a cylinder and is closed at its ends by suitable covers; the
upper end has an opening adapted to be screwed or otherwise connected to the tap
or other liquid outlet. The said opening is provided with a valve which when the
apparatus is in its normal position is open; the said valve is connected to a second
valve which closes an opening or outlet in the lower part of the vessel, and which
valve carries the discharge-nozzle normally kept closed by means of a spring or
springs. In the upper cover of the apparatus there are two vents, one of which is
normally closed and the other normally open, the valves of the vents being operated
simultaneously with the other valves. The discharge-nozzle of the apparatus is
provided with a funnel to catch any drip.
By this arrangement if a measured quantity of liquid is to be drawn off, the
mouth of the bottle or other vessel is placed over the discharge-nozzle and pressed
upwards thereby opening the valve of the discharge-nozzle and closing the inlet,
at the same time opening one vent and closing the other thus allowing of the
contents of the vessel being drawn off; the bottle being then removed, the parts
will return to their normal position, and the vessel will be again filled from the
cask or other source of supply.
In some cases instead of using two vents as hereinbefore described I can employ
a spring vent to be operated by the finger.

COMPLETE SPECIFICATION.
An Improved Tap or Apparatus for Drawing Off Measured Quantities
of Liquid.
I, RICHARD EDWARD HARRISON, of Anglesea House, London Road,
St. Leonards, in the County of Sussex, Manufacturer, 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 the construction of a novel and simple apparatus which
can be applied to any ordinary tap or liquid outlet to allow of measured quantities
of liquid being drawn off.
In constructing my improved apparatus I employ a vessel or receiver which will
contain a known quantity or measure of liquid. This vessel is advantageously
made in the form of a cylinder and is closed at its ends by suitable covers; the
upper end has an opening or nozzle adapted to be screwed or otherwise connected
to the tap or other liquid outlet. The said nozzle is provided with a valve which

page_text: when the apparatus is in its normal position is open; the said valve is connected to
a second valve which closes an outlet in the lower part of the vessel, and which
valve carries the discharge-nozzle and is normally kept closed by means of a
spring or springs. In the upper cover of the apparatus is an air-valve. The
discharge-nozzle of the apparatus is provided with a funnel or cup to catch
any drip.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-
Figure 1 is a plan of a tap or apparatus constructed according to my invention for
drawing off measured quantities of liquid:
Figure 2 is an elevation of the same partly in section, the section being. taken
on the line A B of Figure 1; and,
Figure 3 is a vertical section on the line C D of Figure 1.
Similar letters in all the figures indicate similar parts.
;
a is the cylindrical vessel or receiver for containing a known quantity or measure
of liquid and are the covers for closing the top and bottom ends respectively
of the vessel a; d is the nozzle adapted to be connected to the outlet oft he cask or
other supply-vessel by means of a thimble e formed with exterior and interior
screw-threads to allow of it being screwed into the nozzle d and onto the said outlet;
is the valve in the nozzle d, the said valve being formed of a hollow plunger
provided with perforations which normally are uncovered and open into the
interior of the vessel a, the valve being then open; h is the valve in the lower part
of the vessel a; this valve works in an opening in the bottom of the vessel a and is
connected to the valve by a rod i; it consists of a number of holes j made in the
upper and closed end of a tube & forming the outlet or discharge nozzle, so that,
when the upper valve f is open, the holes j do not open into the interior of the
vessel a and the outlet tube is therefore closed and vice versa; 1, 1 are the
springs for normally keeping the upper valve open and the lower valve closed,
the said springs for this purpose bearing against the underside of the cover c and
upon a plate m carried by the tube k; n is the air-valve in the upper cover b, which
valve is arranged to admit air to the interior of the vessel a through passages a¹ a³,
while the liquid is being drawn off; it is made of cork or other suitable substance
which will float in liquid so that, when the vessel is full, it rises and closes the
aperture thereby stopping the flow of the liquid and preventing its overflow; o is
the funnel or cup on the discharge-tube or nozzle k for catching any drip from the
valve h, the drip then running through holes » into the interior of the tube k and
passing off therethrough into the bottle or other recipient.
By this arrangement if a measured quantity of liquid is to be drawn off, the
mouth of the bottle or other vessel is placed over the discharge-nozzle or tube k
and pressed upwards, thereby opening the valve of the discharge-nozzle and
closing the inlet-valve, thus allowing of the contents of the vessel being drawn
off; air meanwhile entering through the valve n; the bottle being then removed,
the springs will cause the parts to return to their normal position, that is to say,
the valve will open, the valve h will close and the vessel will be again filled
from the cask or other source of supply.
In some cases instead of using an air-valve as herein before described I can
employ a spring vent to be operated by the finger; or a small tube can lead from
the cover to a position above the level of the liquid in the supply-vessel but in
this case of course the contents of the tube would have to be reckoned as part of
the measured quantity of liquid. Further the vessel can be marked with graduated
lines to admit of a measured portion of the contents of the vessel a being
drawn off.
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
1. A tan or annaratus for drawing off measured quantities of liquid consisting of

page_text: a vessel having valves in its upper and lower ends, the said valves being connected
together and the upper valve being normally kept open and the lower valve closed
by means of a spring or springs, suitable means being also provided for the
admission of air to the vessel, substantially as hereinbefore described.
2. In a tap or apparatus of the kind referred to in Claim 1 the use of a valve
which will allow the admission of air to the measuring vessel when drawing off the
liquid therefrom and which will automatically close when the vessel becomes full,
substantially as hereinbefore described and illustrated in the accompanying
drawings.
3. The improved tap or apparatus for drawing off measured quantities of liquid
hereinbefore described and illustrated in the accompanying drawings.
