do hereby declare the nature of this invention to be as follows:-

The chief object of my invention is to provide efficient and effective means wheroby.
liquids may be transferred when required from one to another or to several compart
ments or cells of divided vessels without having access to the interior of the receptacle
or receptacles, and the invention although particularly applicable in connection with
chemical batteries is available for use as a tap or cock generally. There is a passage
or way from end to end of the tap or cock with slots opening into the compartment or
cell from which the liquid is to be taken or drawn; the passage way is screw threaded
nearly or partially the whole of its length in which a correspondingly screw threaded
plug or spindle works having a key head or other convenient provision at its end for
operating the plug or spindle; near to the inner end of this plug or spindle is formed
a conical or other suitably shaped shoulder which comes up against a correspondingly
shaped seating when the tap is screwed up or closed but when unscrewed or partially
so the liquid can pass through the slots or openings in the plug and between the
conical or other shaped shoulder of the plug or spindle and its seating; the said plug
or spindle being operated from the outside of the vessel to which it is applied by the
key or other convenient means as aforesaid.

the slots are in the vessel or compartment containing the liquid and so long as the
shoulder of the spindle is tightly screwed up on to its seating no liquid can pass from
one cell or compartment to the other but immediately the shoulder of the spindle or

or Conduits, for Cutting off and Turning on the Supply of Liquids.
and for Regulating the Flow of same.
1, Sir WILLIAM VAVASOUR, Baronet, of 50 Holborn Viaduct, in the City of London,
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 :-
The chief object of my invention is to provide efficient and effective means
whereby liquids may be transferred when required from one to another, or to several
compartments or cells of divided vessels, without having access to the interior of
the receptacle or receptacles, and the invention although particularly applicable in
connection with chemical batteries, is available for use as a tap or cock generally.
My invention will be best understood by describing the same with reference to
the accompanying drawings in which similar letters of reference refer to like parts in
the various figures.
Figure 1 is a central longitudinal vertical section showing a valve constructed
according to my invention such as would be applied to a closed case containing battery
cells; Figure 2 is a plan of same, and Figure 3 is a section shewing the valve or tap
in its open position, Figure 1 shewing the same valve closed.
There is a passage or way from end to end of the tube A which forms the body of.
the tap or cock, and the said tube A is formed with slots B opening into the compart-
ment or cell from which the liquid is to be taken or drawn, this is indicated in the
drawings by the space C between the portions of the partition shewn; the passage
way through the tube A is screw threaded internally nearly or partially the whole of
its length as far as the slot B. screwing into which thread there is a correspondingly
screw threaded or otherwise water tight plug or spindle D having a key head D)' or
other convenient provision at its end for operating the plug or spindle D.
Near to the inner end of this plug or spindle D is formed a conical or other suitably
shaped shoulder D which comes up against a correspondingly shaped seating formed
in the tube body A when the tap is screwed up or closed, the parts then being in the
position shewn at Figure 1, but when unscrewed, or partially so, as is shewn at
Figure 3, the liquid can pass through the slots or openings B B and between the
conical or other shaped shoulder 12 of the plug or spindle D and its seating; the said
plug or spindle is operated from the outside of the vessel to which it is applied by the
key head 1 or other convenient means as aforesaid. The body A of the tap is shewn
screw-threaded on the outer surface and is thus or by other convenient or suitable
means secured into the partitions by means of hack nuts.
In applying the tap for example as is shewn in the accompanying drawings to a
closed-in vessel or vat having two compartments or cells CC, one of which C is filled
with liquid, some of which it is periodically or continuously required to transfer to

page_text: the other compartment or other cell C, and that without removing the cover, or
unclosing the receptacles, I arrange the appliance as shewn in such manner that the
slots B B are in the vessel or compartment C containing the liquid, and so long as the
shoulder 2 of the spindle D is tightly screwed up on to its seating no liquid can pass
from one cell or compartment to the other, as is clearly seen by reference to Figure 1,
but immediately the shoulder D' of the spindle or plug D is removed from its seating
by unscrewing same by the key D¹ from the outside, the liquid can flow through the
tap to the other compartment marked C, in the quantity and at the speed required,
according to the extent to which the spindle is removed from its seating, and which
can be regulated to the greatest nicety by the screw adjustment according to the
purposes to which the tap is applied. The spindle or plug D may pass completely
through the aperture in the tap and.in that case its inner extension D³ affords
a means of clearing the tap of any extraneous matter that may collect therein.
If it is necessary to reverse the action, that is, to draw liquid from the opposite
compartment to that before referred to, a similar action takes place only in the reverse
direction. Several compartments, or cells may, by extension, be supplied with liquid
in a similar way, it being only necessary to modify the appliance accordingly, to suit
the particular purpose to which the invention is applied.
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. The valves or appliances for cutting off and turning on the supply of liquids and
for regulating the flow of same from one compartment to another of a closed divided
vessel having access for manipulation with the interior of same from 'the outside
substantially as set forth.
2. In valves or appliances for cutting off and turning on the supply of liquids and
for regulating the flow of same from one compartment to another of a closed divided
vessel, without having access to the interior of same; the tube body A having slots B,
and formed with valve seating, in combination with the spindle D cone or other
valve D2 and formed with or without the extension D³ for clearing the passage, all
substantially as is described and shewn in the foregoing specification with reference to
the accompanying drawings.
