PROVISIONAL SPECIFICATION.
Apparatus for the Mixing and similar Treatment of Fluids.
I, ALPHONSE LEVY, of No. 12, Schlosserstrasse, Colmar, in Alsace, German
Empire, Merchant, do hereby declare the nature of this invention to be as
follows;-
This invention consists of a double concentric pipe service connected with a four-
way cock, through which two different liquids can pass alternately through the
inner and outer concentric pipes respectively, by suitable rotation of the plug
which is seated in a casing having four orifices.
The accompanying drawings, show, as an example, how such a device may be
constructed.
Figures 1 and 2 are vertical sections, and Figure 3 is a horizontal section on
the line A A of Figure 1.
The casing a of the cock has four orifices I, II, III and IV, designed for the
entrance and exit of liquids respectively as hereinafter explained. These orifices
are arranged at right angles and are therefore opposite one another
The exit orifices I and II form the mouths of channels which run through the
casing in directions approximately parallel to one another and pass through the
flanged end 6 of the casing a, to which is connected a flanged pipe c conveniently
attached by bolts and nuts d. The end of the flanged pipe c has an interior screw-
thread into which is screwed the exterior concentric pipe h. The channel of the
exit orifice II has an interior screw-thread at the end e to receive the screw-
threaded inner concentric tube g. The plug k has four passages or channels;
those with the orifices 1, 3, and 2, 4, respectively are at right angles to each other
and one above the other; the other two with orifices 5, 6, and 7, 8, respectively
pass below the upper one 2, 4, of the before mentioned cross-channels, so that
their orifices 5, 6, 7, 8, are situated respectively half-way between the
orifices I, II, III, IV, of the before mentioned cross channels on the periphery of
the plug, see Figure 3.
Therefore if the plug is rotated 45°, the orifices 5, 6, 7, 8, will communicate
with the orifices I, II, III, IV, of the casing a instead of the plug orifices 1, 2, 3, 4,
which are shown in communication with the said orifices of the casing in the
drawings.
In the position of the plug k, as shown in Figure 3, the liquids entering at c
and y pass into the pipes h and g respectively through the orifices 1 and 2 of the
plug and casing. When now the plug is rotated 45° as before mentioned in the
direction of the arrow v, the feed of the liquids is reversed, i.e. the liquids enter-
ing at a and y pass into the pipes and respectively through the orifices II and I
of the casing. A rotation of 22° relative to the above positions closes the cock.
The concentric pipes g and h allow of the mixing or similar treatment of the
liquids passing therethrough. One or other of the services may eventually be
cleansed without interruption of the working of the apparatus.

page_text: This alternating cock and concentric tubes may be used for instance in breweries
and similar establishments. As an example, beer may be introduced at a and
water at y, Figure 3. In the position of the plug as shown in the drawings these
liquids pass to the pipes and g respectively; if the plug k is rotated 45° in
the direction of the arrow the beer introduced at a passes into the pipe g and the
water introduced at y passes into the pipe h. In this manner the beer is mixed
with the water and at the same time the pipes through which the beer passes are
alternately cleansed by water.
In order to heat liquid passing through one of the services, heated air or steam
may be passed through the other service.

Apparatus for the mixing and similar Treatment of Fluids.
I, ALPHONSE LEVY, of No. 12, Schlosserstrasse, Colmar, in Alsace, German
Empire, Merchant, 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 consists of a double concentric pipe surface connected with a four-
way cock, through which two different liquids can pass alternately through the
inner and outer concentric pipes respectively, by suitable rotation of the plug]
which is seated in a casing having four orifices.
In order that my invention may be the better understood I will now proceed to
describe the same with reference to the drawings accompanying the Provisional
Specification.
Figures 1 and 2 are vertical sections and
Figure 3 is a horizontal section on the line A A. of Figure 1.
The casing a of the cock has four orifices I, II, III and IV, designed for the
entrance and exit of liquids respectively' as hereinafter explained. These orifices
are arranged at right angles and are therefore opposite one another.
The exit orifices I and II form the mouths of channels which run through the
casing in directions approximate parallel to one another and pass through the
flanged end of the casing a, to which is connected a flanged pipe c conveniently
attached by bolts and nuts d. The end of the flanged pipe c has an interior screw-
thread into which is screwed the exterior concentric pipe h. The channel of the
exit orifice II has an interior screw-thread at the end e to receive the screw-
threaded inner concentric tube . The plug khas four channels;
those with the orifices 1, 3, and 2, 4, respectively are at right angles to each other
and one above the other; the other two with orifices 5, 6, and 7, 8, respectively
pass below the upper one 2, 4, of the before mentioned cross-channels, so that
their orifices 5, 6, 7, 8, are situated respectively half-way between the
orifices I, II, III, IV of the before mentioned cross channels on the periphery of
the plug see Figure 3.
Therefore, if the plug k is rotated 45°, the orifices 5, 6, 7, 8, will communicate
with the orifices I, II, III, IV, of the casing a instead of the plug orifices 1, 2, 3, 4,
which are shown in communication with the orifices of the casing in the drawings.
In the position of the plug k, as shown in Figure 3 the liquids entering at

page_text: and y pass into the pipes h and g respectively through the orifices 1 and 2 of the
plug and casing. When now the plug is rotated 45° as before mentioned in the
direction of the arrow v, the feed of the liquids is reversed, i.e. the liquids enter-
ing at x and y pass into the pipes g and h respectively through the orifices II and I
of the casing. A rotation of 222° relative to the above positions closes the cock.
The concentric pipes g and h allow of the mixing or similar treatment of the
liquids passing therethrough. One or other of the services may eventually be
cleansed without interruption of the working of the apparatus.
This alternating cock and concentric tubes may be used for instance in breweries
and similar establishments. As an example beer may be introduced at a and
water at y, Figure 3. In the position of the plug as shown in the drawings these
liquids pass to the pipes h and g respectively; if the plug k is rotated 45° in
the direction of the arrow the beer introduced at a passes into the pipe 9 and the
water introduced at y passes into the pipe h. In this manner the beer is mixed
with the water and at the same time the pipes through which the beer passes are
alternately cleansed by water.
In order to heat a liquid passing through one of the services, heated air or steam
may be passed through the other service.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
Apparatus for the mixing or similar treatment of liquids provided with double
concentric pipes connected with a four way cock having two passages or channels I
and II communicating with the concentric pipes g and h and constructed so that
the plug k, which has four passages separate from one another, can be adjusted
so that the liquid or liquids pass alternately through the inner and the outer
tube respectively.
