I, THEODORE ALBERT VENIMORE of 56 Rushmore Road, Clapton in the County of
Middlesex, Mechanical Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to taps or cocks for mixing or combining two supplies of
water or other liquids having different pressures or different temperatures or both
combined, and has principally for object to prevent the throttling of the supply of
water or other liquid having the lower pressure, by the supply having the higher
pressure, which has heretofore been the case.
The invention has also for object to mix or combine the said supplies of water or
other liquids in any required proportion.
In carrying my invention into practice, I form the tap or cock with the two usual
inlets, i one for the admission of the water or other liquid having the higher
pressure, and the other for the admission of the water or other liquid having the
lower pressure. The plug of the tap or cock I provide with two ports corresponding
with the said inlets, the said ports opening into two separate chambers in the said
plug. The chamber whose port corresponds with the inlet for the water or other
liquid having the higher pressure, is provided with a nozzle, which projects into the
other chamber also provided with a nozzle in which the said supplies mix while
issuing from the tap or cock. By this arrangement if the plug of the tap or cock be
turned or moved so that the said supplies of water or other liquids can enter their
respective chambers, the excess of pressure of the one supply above the other supply,
will cause the former to pass into its chamber and from its nozzle through the other.
chamber, at such a velocity as to increase by induction the latter supply instead of
throttling it as in taps or cocks of this class as heretofore constructed.
For the purpose of delivering a mixture or combination of the two liquids in any
required proportion or either of them alone, I make the ports in the plug of the tap

either one of the said liquids until it is entirely cut off, while maintaining the full
supply of the other.
When using my improved tap or cock in conjunction with a hose or its equivalent
for shampooing and other purposes, I sometimes provide the said tap or cock with a
casing or its equivalent, to hide the unsightly joint made where the hose joins the said
tap or cock.

Improvements in Taps or Cocks for Mixing or. Combining Two
Supplies of Water or other Liquids having Different Pressures
or Different Temperatures or Both Combined.
I, THEODORE ALBERT VENIMORE of 56 Rushmore Road, Clapton, in the county of
Middlesex, Mechanical Engineer, do hereby declare the nature of this invention, and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to taps or cocks for mixing or combining two supplies of
water or other liquids, having different pressures, or different temperatures, or both
combined, and has principally for object to prevent the throttling of the supply of
water or other liquid having the lower pressure, by the supply having the higher
pressure, which has heretofore been the case. The invention has also for object to
mix or combine the said supplies of water or other liquids in any required
proportion.
In carrying my invention into practice, I form the tap or cock with the two usual
inlets, viz., one for the admission of the water or other liquid having the higher
pressure, and the other for the admission of the water or other liquid having the lower
pressure. The plug of the tap or cock I provide with two ports corresponding with
the said inlets, the said ports opening into two separate chambers in the said plug.
The chamber whose port corresponds with the inlet for the water or other liquid
having the higher pressure, is provided with a nozzle, which projects into the other
chamber in which the said supplies mix while passing through the tap or cock.
this arrangement if the plug of the tap or cock be turned or moved so that the said
supplies of water or other liquids can enter their respective chambers, the excess of
pressure of the one supply above the other supply, will cause the former to pass into
its chamber and from its nozzle through the other chamber at such a velocity, as to
increase by induction the latter supply, instead of throttling it as in taps or cocks of
this class as heretofore constructed.
By
For the purpose of delivering a mixture or combination of the two, liquids in any
required proportion, or either of them alone, I make the ports in the plug of the tap

page_text: or cock, of such form that by turning the said plug, I can diminish the supply of
either one of the said liquids until it is cut off, while maintaining the full supply of
the other.
When using my improved tap or cock in conjunction with a hose or its equivalent
for shampooing and other purposes, I sometimes provide the said tap or cock with a
casing or its equivalent, to hide the unsightly joint made where the hose joins the
said tap or cock.
To enable my invention to be clearly understood will describe the same by
reference to the accompanying drawing, in which,
Figures 1 and 2 are a front elevation and plan respectively of a shampooing tap as
constructed according to my invention, and,
Figures 3 and 4 are a vertical and horizontal section respectively of the same.
Similar reference letters indicate the same parts throughout the drawing.
a and are the two usual inlets to the tap, the inlet a serving for the admission
of the water having the higher pressure, and the inlet for the admission of the
water having the lower pressure, the two supplies of water being of different
temperatures.
c is the plug of the tap, and d, e are the two ports therein which correspond
respectively with the inlets a and b.
and gare the two chambers in the plug c into which the ports d and e open
respectively, the chamber being provided with the nozzle which projects into the
other chamber g, in which the two supplies of water mix while passing through
the tap.
i is the outlet nozzle of the tap and j is the handle thereof which is attached to the
plug c.
By this arrangement if the plug c be turned into the position shewn in
fig. 3, the excess of pressure of the water passing through the inlet a, above the
pressure of that passing through the inlet b, will cause tlie former to pass into its
chamber and from its nozzle with such velocity as to increase by induction the
supply passing through the inlet b, the two supplies finally issuing from the nozzle i.
As shewn in figure 4 the ports d and e are extended partly round the plug e in
opposite directions. By this construction the plug can be operated so as to diminish
the supply of either of the supplies of water until it is entirely cut off, at the same
time maintaining the full supply of the other.
is the casing which I provide for hiding the unsightly joint made by the hose
being attached to the nozzle i.
Although I have only shewn and described a shampooing tap, it will be obvious
that taps or cocks for other purposes can be similarly constructed without departing
from the principle of my invention.
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
1 claim is,
i
1. A tap or cock for mixing or combining two supplies of any liquid or liquids,
so constructed that the flow of the one liquid induces the flow of the other liquid ·
substantially as described.
2. A tap or cock for mixing or combining two supplies of any liquid or liquids in
any desired proportion substantially as described.
3. The improved tap or cock, substantially as described and represented in the
accompanying drawing.
