Apparatus for Dispensing Mixtures of Liquids.
I, ROBERT WILLOUGHBY VINING, of 49, Grange Park, Ealing, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for dispensing measured quantities of two
or more liquids, mixed or partly mixed together. For this purpose, I provide
a vessel or urn containing a supply of one of the liquids, such for instance as
hot water, and in this urn I fix two receptacles of known measure, each having
an air pipe extending up above the body of liquid in the urn. I provide
another vessel containing a supply of another of the liquids, such for instance
as bovril, this vessel being placed above a stop cock, the plug of which can be
turned by a handle and pawl acting on a ratchet, one quarter of a revolution
at a time. The body of this stop cock communicates with the two receptacles in
the urn and also with the vessel above it, and the plug of the cock has two
cavities in it of known capacity, and passages so arranged that it operates in
the following manner.
In one position of the plug a cavity in it is receiving liquid from the vessel
above, while a passage is allowing issue of liquid from one of the receptacles
along with the contents of the other cavity which had been previously filled with
liquid from the vessel above. At the same time by a passage in the plug, liquid
is filling the other of the receptacles in the urn. On turning the plug another
quarter round, the portion of liquid received in the cavity in its former position
is delivered along with liquid from the receptacle which had then been filled,
and thus the two cavities and the two receptacles are alternately filled and
emptied.
By providing additional vessels and receptacles and additional cavities and
passages in the plug of the cock, more than two liquids might be simultaneously
delivered in the manner above described.
Instead of a stop-cock having a rotating plug, a reciprocating slide valve
having suitable cavities and passages might be arranged to operate in like
manner.

tained in and by the following statement:-
My invention relates to apparatus for dispensing measured quantities of two
liquids, mixed or partly mixed together, as I shall describe with reference to
the accompanying drawings.
Fig. 1 is an elevation partly sectional of apparatus according to my invention.
Figs. 2 and 3 are longitudinal sections of the cock on vertical and horizontal planes
respectively.
These
a is a vessel or urn containing one of the liquids to be dispensed, for
instance water, and b is a vessel containing the other liquid, such for instance
as bovril. In the urn a are fixed two receptacles c and d each of known capacity
and having an air pipe extending above the level of the liquid in a.
two vessels communicate by pipes to passages e, f in the casing of a stop cock
leading to its opposite ends. From a there is an opening at g, from which
passages j branch to the opposite ends of the cock casing, and in the front
part of the casing is a cavity h communicating with the outlet nozzle o. Through
the plug of the cock there are two passages k and 7 at right angles to each other,
the one in such position as to make communication between e and i, the
other to make communication between f and j. There are also two passages m
and nat right angles to each other, each of definite capacity for receiving
liquid from b.
The plug can be turned by a handle p carrying a spring pawl which acts on
a ratchet wheel 9 so that by each stroke of the handle the plug can be turned
one quarter round.
When the plug is in the position shewn in Figs. 2 and 3, liquid from 6 charges
the passagen and liquid from a flows by g, j, 1, f to the vessel d charging it:
also liquid from the vessel c flows by e through m along with that which had
previously charged m to the cavity h and thence to the outlet o. On turning
the plug one quarter round the vessel c is charged from the liquid in a by g, i, k
and e, and the vessel d is discharged by f, n, h, o along with the liquid that was

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:
Apparatus for dispensing mixtures of liquids constructed and operating sub-
stantially as described and illustrated.
