IMPROVEMENTS IN COMBINED' MEASURING AND FILLING APPARATUS FOR LIQUIDS
Year: 1884

page_text: I WILLIAM ROBERT MAUD of Pontefract in the County of York Chemist and
Druggist do hereby declare the nature of my invention for, "IMPROVEMENTS IN
COMBINED' MEASURING AND FILLING APPARATUS FOR LIQUIDS to be as follows:→
My invention consists in an apparatus for readily supplying or transferring to
bottles or other vessels a definite and measured quantity of any required liquid.
For this purpose I employ a measuring vessel which acts also as a funnel and is
provided with a valve capable of being opened by pressure and closed automatically
by a spring whereby any required or measured quantity of liquid can be. readily
transferred from the measuring vessel to the bottle or other vessel into which it is
to be passed.
The measuring vessel which I employ may be of any convenient form or shape
graduated if desired and having at or near the base thereof a short length of tube
attached so as to form a duct or passage.
Within this fixed tube is placed a sliding perforated tube having a plate at one
end and arranged so as to act as a valve: This tube is pressed downwards by a
spring in such a manner that the passage remains closed except when the pressure
of the spring is overcome as hereinafter described. .
Near the outer end of the sliding tube there is fastened a projecting collar or
wings whereby when the end of this tube is inserted into the neck of a bottle or
other vessel the collar or wings cannot pass and the result is that on pressing down
the whole apparatus the valve is opened by forcing up the tube against the action
of the spring and the liquid can pass freely into the bottle or other vessel.
On relieving the pressure the flow of liquid ceases at once.
For convenience the apparatus is supported on suitable legs.

page_text: I WILLIAM ROBERT MAUD of Pontefract in the County of York Chemist and
Druggist do hereby. declare the nature of my invention for IMPROVEMENTS IN
COMBINED MEASURING AND FILLING APPARATUS FOR LIQUIDS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention consists in an apparatus for readily supplying or transferring to
bottles or other vessels a definite and measured quantity of any required liquid.
For this purpose I employ a measuring vessel which acts also as a funnel and is
provided with a valve capable of being opened by pressure and closed automatically
by a spring whereby any required or measured quantity of liquid can be readily
transferred from the measuring vessel, to the bottle or other vessel into which it is
to be passed.
The measuring vessel which I employ may be of any convenient form or shape
graduated if desired and having at or near the base thereof a short length of tube
attached so as to form a duct or passage. Within this fixed tube is placed a sliding
perforated tube having a plate at one end and arranged so as to act as a valve.
This tube is pressed downwards by a spring in such a manner that the passage
remains closed except when the pressure of the spring is overcome as hereinafter
described.
Near the outer end of the sliding tube there is fastened a projecting collar or
wings whereby when the end of this tube is inserted into the neck of a bottle or
other vessel the collar or wings cannot pass and the result is that on pressing down
the whole apparatus the valve is opened by forcing up the tube against the action
of the spring and the liquid can pass freely into the bottle or other vessel. On
relieving the pressure the flow of liquid ceases at once.
For convenience the apparatus is supported on suitable legs." :
In the annexed sheet of drawings Figure 1 shows my invention as applied to a
measuring vessel and Figures 2, 3, 4, 5, 6 show details of parts of the apparatus
for transferring the liquid in a definite or measured : quantity. The vessel A. in
Figure 1 is a measuring vessel of any convenient form or shape graduated or
otherwise and at any convenient part usually the base thereof I attach a short-
piece of tube K K shown separately in Figure 6 having a flange or shoulder which
is firmly secured to the material of the vessel so as to form a passage or opening
in which the sliding perforated tube BB shown in Figures 2, 3 and 4 is passed.
The tube B B is closed at the upper end by a plate which has a projecting rim on
which a conical shoulder G G is formed so as to fit a conical seat on the tube K K
as shown at E E and form an ordinary valve. The upper part of the tube B B is
perforated at E E so that the liquid contained in A may pass out when the-plate
closing the upper end of the tube is raised from its seating. The conical valve GG
resting on the seat E E'is shown by way of examplo as any other ordinary form of
valve may be adopted. When the apparatus is made of pewter or soft metal a
washer of india rubber. or other elastic material may be applied in place of a
ground joint valve. Such a washer is shown at F F in Figure 3.

The tube or pipe B B is screwed at the part C and a short length of tube D D is
screwed upon the same as shown in Figures 2 and 3. The opening of the tube DD
is enlarged so as to fit the outside of the tube K K and can slide along it for a
short distance until stopped by the shoulder A. A.
Figure 2 shows the position of B B when the valve is closed and Figure 3 shows
the same when the valve is open.
A spring SS which is preferably a spiral spring wound round the outside of K K
tends always to press the tube B B downwards and to keep the valve closed or the
tube B B may be loaded so as to close by its own weight.
.
When the apparatus is inserted in the neck of a bottle M N it is convenient
that a projecting collar or wings formed on D D should rest upon the neck as
shown in Figure 1 whereupon by pressing down the apparatus the sliding tube is
forced upwards so as to open the valve and allow a free passage for the liquid: on
relieving the pressure the valve closes automatically by the action of the spring.
I prefer to make this apparatus of brass pewter or copper but any of the parts
may be made of other material such as glass, china, or earthenware if desired.
I make no claim to the use of any particular material nor do I conf ne myself
to the precise details of construction specified as the same may be varied and
modifications may be made without departing from the principle of my invention.
By this apparatus the following advantages are secured namely (1) the necessity of
using separate articles, namely, a measure and a funnel is obviated and thus it acts
as a labour-saving machine especially when a large number of bottles or vessels are
to be filled at the same time (2) It is much more cleanly in use as in taking hold of
an ordinary funnel the hands are almost of necessity soiled by whatever liquid is
passed through (3) It prevents waste and consequent damage which occurs
whenever (as is frequently the case) more liquid is poured into the funnel than the
bottle or vessel will contain (4) It thus lessens the risk of fire by preventing
(during the act of measuring) the spilling of inflammable liquids such as petroleum
benzoline or any highly rectified spirits.
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
The general construction and arrangement of combined measuring and filling
apparatus whereby a valve is opened for the passage of liquid into a bottle or
vessel intended for its reception by means of the downward pressure of the whole
apparatus upon the mouth or neck of the said bottle or vessel and is closed
automatically when the pressure is relieved substantially as and for the purpose
described.
