An Improved Device or 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 has reference to an improved construction of device or apparatus
for delivering regulated quantities of liquids, being specially applicable for use in
connection with the filling of ink-wells in public schools or other educational
establishments.
The invention will be understood from the following description in reference to
the accompanying drawings in which
Figure 1 is a sectional view of a device or contrivance for the purpose named
and constructed in accordance with this invention.
Figure 2 is an elevation of the same shewing it in position during the filling of
an ink-well.
Figures 3 and 4 are modifications.
The device shewn in the drawings and constituting the invention is adapted to
be screwed on the neck of a tin, can or other vessel or receptacle in which the
main liquid supply is carried or stored.
The device is screw-threaded at A for such purpose and is formed with a
serrated or milled edged enlargement B to facilitate its being screwed on or
removed from the vessel referred to.
Fixed centrally to the underside of the upper screwed end is a delivery tube or
pipe C communicating with the hollow interior A¹ of the screwed upper portion of
the apparatus. This tube is formed with an angular or inclined end and has a
plate C soldered or otherwise fixed to the end thereof. At the lowest point in the
longer end of the tube there is an opening C² to permit of the liquid passing
through and at the extreme point in the shorter end of the said tube an opening (s
is provided for the admission of air into the tube.
Concentrically with the delivery tube C is a sleeve D capable of moving up
and down on said tube and maintained in its lowered position by means of the spiral
spring E encircling the said sleeve and compressible between the underside of the
screwed upper portion A and a collar D¹ formed on or integrally with the sleeve.
The collar D¹ is provided on one side with a horizontal extension D' perforated
centrally to slide up and down on the guide rod or spindle F the upper end of
which is rigidly screwed or otherwise fixed in A.
On the opposite side of the collar D¹ there is a depending angular extension D'
adapted to rest on the side, neck or other convenient part of the to-be-filled vessel
and on a little downward pressure being brought to bear upon the device will raise
the sleeve and allow the liquid to flow through the delivery tube into the vessel
required to be filled as illustrated in the ink-well in Figure 2.
The sleeve D is restricted in its upward movement by the underside A' of the
upper part of the device and in its downward movement by the lower end thereof
coming into contact with the marginal edge of the plate C₁ which is made slightly
larger in diameter than the end of the delivery tube so that the end of the sleeve
may rest and be supported thereon.
The position of the delivery orifice C² and the air opening C" bear such relation
to each other that upon the device being removed from a filled vessel, the delivery
orifice will be entirely closed or covered by the descent of the sleeve D before the
latter has reached the air admission opening C³ for the same purpose.

page_text: The extent of the movement of the sleeve D should be such as to allow the air
opening to be near the mouth or the upper end of the vessel during the time it is
being filled as indicated most clearly in Figure 2.
A pad G of india-rubber or other suitable material is fixed round the marginal
edge of the plate C' so that the lower end of the sleeve may fit closely thereon
and prevent the drip of the liquid when the device is withdrawn from a filled
vessel.
In the modification shewn in Figure 3 the spring E which influences the move-
ment of the sleeve D and maintains it in its lowered position is placed round the
guide rod or spindle F or instead of the spring being on the exterior of the
sleeve as in Figure 2 the said sleeve may be slightly increased in diameter and
the spring allowed to encircle the delivery tube C and be partly enclosed by the
enlarged part D' of the sleeve as indicated in Figure 4.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a device or apparatus for delivering regulated quantities of liquids the
combination of intermediate chamber such as A A B delivering pipe such as C
provided with liquid outlet C and air inlet C³ substantially as described and
illustrated in the accompanying drawing.
2. In a device or apparatus for delivering regulated quantities of liquids the
combination with an intermediate chamber such as A. A¹ B and delivery pipe such
as C provided with liquid outlet C³, of a spring controlled sleeve such as D
substantially as described and illustrated in the accompanying drawing.
3. The improved device or apparatus for delivering regulated quantities of
liquids substantially as described and illustrated in the accompanying drawing.
Dated this 24th day of September 1891.
