PROVISIONAL SPECIFICATION.
An Improved Mixing Cock.
We, WILLIAM HENRY OSBORNE and THOMAS WILLIAM GARRETT, trading
as Osborne Garrett and Company, of Frith Street Soho, London, Merchants,. do
hereby declare the nature of this invention to be as follows:-.
The arrangement of this tap differs from any other used for shampooing, by
having a triangular shaped hole in plug.
This triangular hole is so arranged that it enables the operator to change the
temperature of the water instantly from hot or cold to tepid.
In other taps in use there is a defect, when the operator brings the lever of tap
to the point indicating tepid, and this defect is, that the temperature is found to be
either too hot or too cold.
I will now proceed to describe my invention.
The tap has two separate passages bored at inlet end, one for conducting hot
water the other for conducting cold water.
The plug working in the barrel of the tap, has a triangular hole, so arranged,
that when either hot or cold water is required, the plug is brought into position, by
turning lever of tap opposite to the engraved words HOT or COLD.
When tepid water is required the lever of tap is turned, and brought opposite to
the engraved word TEPID on the front of tap.
The triangular hole in the plug is now brought into communication with each of
the passages for hot and cold water at the same time and allows hot and cold water
to flow through and unite in plug, thus producing water of a tepid temperature,
which is discharged through vertical passage in plug.
Instead of the above described hole in the plug, a series of small holes of
piercings may be arranged in triangular form, or a slot or a hole of a rectangular
form may be used.
Although I have described my invention only in connection with a shampooing.
tap, yet it is applicable to all kinds of taps, where two or more liquids are required
to be united.

COMPLETE SPECIFICATION.
An Improved Mixing Cook.
We, WILLIAM HENRY OSBORNE and THOMAS WILLIAM GARRETT of Frith
Street, Soho, in the City of London, Merchants and Factors, '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 taps or cocks, for the purpose of supplying hot,
cold, or tepid water, and used principally for shampooing purposes, und which said
taps or cocks, enable the operator to change the temperature of the water instantly
from hot, or cold, to tepid, or vice-versa.
These said taps or cocks, as usually constructed, are found to be defective for the
supplying of tepid water, in consequence of the pressure of the cold water (which
is generally taken off the main supply) being greater than the pressure of the hot

page_text: water or vice-versa, thereby causing the temperature of the water to be very
irregular.
of
Now, the object of this invention is to so construct the ports or passages in the
interior of the tap or cock, that on tepid water being required, the inlet passage
the cold water, shall be partially closed, while the inlet passage of the hot water,
shall be fully opened, thus reducing the body of inflowing cold water, and by this
means the beforementioned defect is overcome.
In carrying out our invention, we take a tap or cock body-part of any suitable
shape, having a hollow conical plug, directed vertically and working within the
middle of the body part of barrel, and provided with inlet passages, for the hot and
cold water respectively, directed horizontally through the back of the tap body-part,
into the plug chamber.
This said hollow conical plug, which is open at its lower end, is horizontally
slotted, or pierced about its middle, in an angular direction (preferably in the shape
of a triangle) and which said slot or piercing, or slots or piercings, constitutes a
port, for the passage of the hot or cold water separately, or both hot and cold
water, into the mixing chamber, formed in the interior of the hollow plug, and
from thence.flows in a vertical direction to the outlet bend and nozzle.
Figure 1 of the accompanying sheet of drawings, represents in longitudinal
vertical section, a shampooing tap or cock, constructed and arranged according to
one form of our invention, and showing the operating plug, in the required position
for the supplying of tepid water.
Figure 2 is a horizontal section on the dotted lines A B Figure 1.
Figure 3 is a vertical section of Figure 1 looking from front of tap, but with the
operating handle, and a portion of the nozzle broken away. This view clearly
shows the port in the hollow plug, and the separate inlet passages for the water,
the port in the plug being fully open to the hot water inlet, but only partially open
to the cold water inlet, thus allowing only sufficient cold water, to reduce the
temperature of the hot to tepid.
Figure 4 is a like section as Figure 3 but with the port or passage in the plug,
brought into communication with the hot water inlet passage only, while Figure 5
shows the said port or passage in communication with the cold water inlet.
Figure 6 is a separate view of the operating plug with the handle broken away,
showing the angular piercing or port in the said plug.
Figure 7 is an elevation of another form of plug, having holes or piercings,
arranged in a triangular direction, instead of a triangular slot as shown in
Figures 1 to 6.
Figure 8 shows a view of still another form of port.
The same letters of reference indicate corresponding parts in the several figures,
a is the tap body or bracket-part having a circular affixing plate a², with sorew
holes therethrough at its back, and its front or barrel-part a³, which is externally
screwed at its extreme ends a, a, respectively, centrally and conically bored-out,
thus forming a plug chamber a, wherein the operating plug fits and works, and
into which the inlet passages a', a³, for the hot and cold water respectively, enter.
These said inlet passages a,.a, for the hot and cold water, are horizontally
formed, in and through, the body part a of the tap, and into which supply pipes b, b³
are screwed or fitted, the one pipe supplying hot water to the hot water inlet, and
the other, cold water to the cold water inlet.
C,
is a conical operating plug, having a mixing chamber c³, vertically disposed,
and open at its lower end c³, and which said open end c, leads into the outlet bend
or nozzle, which is screwed onto the lower end of the barrel a', of the tap a.
This operating plug e, has a slot or piercing e, or a series of slots, or piercings,
of a angular formation, cut through the walls of the said plug, and opposite to the
water entrances, which constitutes a inlet port for the passage of the water, from.
the hot and cold water inlets a', as, into the mixing chamber c, which is common
to both.
c, is the shank of the operating plug e, having a operating handle e, for the

page_text: turning of the said plug, and around and on which, watertight packing means,
consisting of packing d, pressure disc d', and screw cap d'; which screws on to the
top end of the barrel a', fits.
Thus, on tepid water being required, the operating plug c, is turned into the
position shown in Figures 1, 2, and 3, when the inlet port of the said plug, is
brought into the position shown, and is fully open to the hot water inlet, but by its
angular formation, partially covers up the inlet of the cold water, thus greatly
reducing the body of inflowing cold water, which can be readily regulated, by a
slight movement of the said plug.
Having now particularly described and ascertained the nature of our inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is,
.
In a shampooing, or mixing tap, or cock, an operating plug, having a augular
slot or piercing, or a series of angular slots, or piercings, formed therein, sub-
stantially as, and for the purpose, as described and set forth in Figures 1 to 8 of
the sheet of drawings.
