PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Delivering Regulated Quantities
of Liquids.
I, ROBERT JELLEY of 26 Derwent Street, Leicester, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention consists in the provision of an apparatus for delivering liquids into
vessels that are to be filled the object of the invention being to automatically fill the
vessels to a required height whether the said vessels be already partly filled or
empty, and to automatically stop the supply when the quantity required to fill the
vessels has been discharged therein, and thus prevent overflowing.
The apparatus is specially applicable for use in the filling of ink-wells for schools
and other institutions although it is equally useful for refilling other vessels with
liquids.
The apparatus forming the subject of this invention is adapted to be screwed or
otherwise fitted on to a principal chamber, tank or can in which the main supply is
stored, and may consist of an approximately conical or other suitably shaped
chamber or nozzle, in the interior and projecting through the lower end of which
may be a spring-encircled spindle carrying preferably two valves one or each
of which may be fixed or loose upon the spindle.
I prefer that the valve which controls the orifice at the bottom of the chamber
through which the liquid is delivered may be fixed upon the spindle and the other
valve, which may be held in position on the spindle between two spiral springs, may
fit loosely thereon, or they may be otherwise suitably placed to adjust themselves
by means of springs or equivalents.
Connected to the lower end of the spindle before mentioned may be another
spindle passing upwards, through an air-chamber, adjacent to and communicating
with the nozzle, and carrying or provided with a valve for regulating the air supply
to the delivering nozzle.
The length of the spindle projecting below the orifice of the nozzle should
be equivalent to the depth of the liquid required to be discharged, plus the length
of movement of the valve spindle.
The action is as follows:-
On the end of the spindle or spindles being pressed against the bottom of the
vessel to be filled the valves in the nozzle are opened and the air chamber valve is
closed.
The air passes from the air chamber into the nozzle and the liquid begins
to flow into the vessel to be filled until it reaches the orifice of the nozzle.
On lifting the apparatus, the valves close the air hole and outlet orifice and the
air valve is simultaneously opened to admit air to the air chamber thereby
destroying or removing the film which forms at the orifice and which would
otherwise prevent the admission of air.
I wish it understood that I do not confine myself strictly to the structural details
set forth, as these may be varied in several instances to effect the same end. For
instance instead of connecting the nozzle valve spindle and the air chamber spindle
at their lower ends, they may be connected at any convenient point in their length
and their simultaneous action may be obtained through the medium of a bell-crank
lever joined at its extreme ends or otherwise to the valves or spindles mentioned, or
by any other suitable or equivalent means.

page_text: The air chamber may also be constructed in various modified forms without
departing from the spirit of the invention.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Delivering Regulated Quantities
of Liquids.
I, ROBERT JELLEY of 26 Derwent Street, Leicester, Engineer, 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 consists in the provision of an apparatus for delivering liquids into
vessels that are to be filled, the object of the invention being to automatically fill
the vessels to a required height whether the said vessels be already partly filled or
empty, and to automatically stop the supply when the quantity required to fill the
vessels has been discharged therein, and thus prevent overflowing.
The apparatus is specially applicable for use in the filling of ink-wells for schools
and other institutions, although it is equally useful for refilling other vessels with
liquids.
The apparatus forming the subject of this invention is adapted to be screwed or
otherwise fitted on to a principal chamber, tank, or can, in which the main supply is
stored, and will be understood from the following description in reference to the
accompanying drawings in which
Figures 1 and 2 are sectional views of the device, with the mechanism in different
positions.
Figure 3 is a detail view.
The contrivance is screw threaded at A to admit of being screwed on to the
supply chamber as before stated.
The liquid after leaving the storage or supply chamber passes into a preferably
circular intermediate chamber B in the upper part of the contrivance from whence
its passage out of same is controlled by the cone valve B¹. This valve is carried on
a vertical spindle C the latter being encircled at its upper end with a spiral
spring C¹ located between the collar D and a cross-bar A¹ extending across the top
of the screwed neck A.
On the lower end of the spindle being pressed on the bottom of an ink-well
or other vessel to be filled, the valve B is raised into the position shewn in
Figure 2 and the spring C' compressed between A and D, but on the spindle being
removed from the filled vessel, the spring C¹ will cause the valve B' to assume the
normal and closed position indicated in Figure 1, when the outpour of liquid
will cease.
The length of spindle C allowed to project beyond the lower end of the delivery
tube A² may vary according to the depth of the vessel being filled, but is equivalent
to the depth of the liquid required to be discharged plus the length of the movement
of the valve spindle C.
At the side of the delivery tube A2 is an air chamber E the supply of air
to same being controlled by a valve F adjustably carried on the screwed end of the
horizontal spindle F¹.
The central portion of this spindle is furnished with a plate F², having
a circular opening F³, Figure 3, into which a cone G on the spindle C partly
enters.
The opposite end of the spindle F¹ is encircled by a spiral spring F held
between one end of the plate F2 and a shoulder H¹ formed in the interior of a
cap H which is screwed at A³ into the side of the chamber B and may be removed

page_text: to admit of the spindle F1 and plate F being fixed in position in the chamber B or
removed therefrom. The spindle F' and plate F2 are maintained in their normal
positions under the influence of the spring F but are moved to the left to close the
air chamber E by the upward travel of the spindle C causing the cone G to enter
the opening F³ in the plate F2 and press it sideways by frictional pressure as shewn
in Figure 2.
The action is as follows:-On the lower end of the spindle C being pressed on
the bottom of an ink-well or other vessel to be filled, it will be moved upwardly so
that the cone valve B' assumes its open position as in Figure 2 to permit of the
liquid passing from the chamber B, into the delivery tube A², and thence to the
vessel being filled.
Simultaneously the spring controlled plate F2 will be moved to the left
and cause the valve F to seal the air chamber E as in Figure 3.
On the contrivance being lifted from the filled vessel the mechanical parts will
assume their normal positions as in Figure 1 and upon the valve F being removed
from the mouth of the air chamber E a current of air will be admitted into the
latter and will destroy any film that may have formed at the mouth of the delivery
tube A².
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an apparatus for distributing regulated quantities of liquids the com-
bination of an intermediate chamber such as B, delivery valve such as B' spring
controlled spindle such as C and delivery tube such as A2 substantially as described
and illustrated in the accompanying drawing.
2. In an apparatus for distributing regulated quantities of liquids, the com-
bination of an air chamber such as E, spring controlled spindle F and valve such
as F, cone such as G, substantially as described and illustrated in the accompanying
drawing.
3. The complete apparatus for distributing regulated quantities of liquids
constructed and operating substantially in the manner described and illustrated in
the accompanying drawing.
