PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Evaporating, Concentrating, and
Distilling Liquids.
We, WILLIAM RENNY WATSON and ROBERT ANDREW ROBERTSON, both of
the firm of The Mirrlees, Watson & Yaryan Company, Limited, 45, Scotland
Street, Glasgow, in the County of Lanark, North Britain, Engineers, do hereby
declare the nature of this invention to be as follows :-
This invention relates to improvements in the construction of apparatus for
evaporating, and distilling liquids, and has for its object to simplify the construction
of such apparatus, and render it more easily packed for transport.
The improvements are more particularly applicable to apparatus similar to those
described in the Specification of Patent of the said William Renny Watson and
Robert Andrew Robertson, No. 11485, A.D. 1888.
In apparatus of this type, the liquid after passing through the vaporizing tubes
in the vessel or vessels forming the apparatus, passes into a separating chamber
which is attached directly to the lower part of the casing enclosing the front ends
of the vaporizing tubes.
According to this invention, we form the separating chamber or chambers for the
single vessel or several vessels into a column, making the necessary connection for
vapor and liquor under treatment by means of piping.

We, WILLIAM RENNY WATSON and ROBERT ANDREW ROBERTSON, both of
The Mirrlees, Watson & Yaryan Company, Limited, of 45, Scotland Street,
Glasgow, North Britain, Engineers, 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 :—
Our invention relates to improvements in the construction of apparatus for
evaporating and distilling liquids, and has for its object to simplify the construction
of such apparatus and render it more easily packed for transport.
The improvements are more particularly applicable to apparatus similar to those
described in the Specification of Patent of the said William Renny Watson and
Robert Andrew Robertson No. 11485, A.D. 1888.
In apparatus of this type, the liquid after passing through the vaporizing tubes
in the vessel or vessels forming the apparatus passes into a separating chamber
which is attached directly to the lower part of the casing enclosing the front ends
of the vaporizing tubes.
According to this invention we form the separating chamber or chambers for the
single vessel or several vessels into a column, making the necessary connection for
vapor and liquor under treatment by means of piping.
In order that our invention may be properly understood and readily carried into
effect we have hereunto appended an explanatory sheet of drawing, which we will
now proceed to describe.
The apparatus shown on the drawing is a triple effect apparatus. The liquor to

page_text: be evaporated, concentrated or distilled enters the apparatus at a, passes through
the series of tubes b', ', ' of the first cylinder A', while the steam enters the first
cylinder A by the pipe c. From the lowest of the tubes 6, the liquor in a partly
concentrated condition with its vapor passes through a pipe or passage d¹ to the
detached chamber B', where the vapor and liquor are separated, the liquor passing
through the pipe or passage to the series of tubes 2, 12, 12 of the second
cylinder A², while the vapor from the first separating chamber B₁ passes through
the pipe to the second cylinder A². The condensed water and incondensable
vapors from the first cylinder A' pass by the pipe gl to the second cylinder A. The
liquor after further concentration in the tubes of the second cylinder passes along
with its vapor through the pipe or passage d² to the second separating chamber B2,
where the liquor and vapor are separated. The liquor passes by the pipe or
passage to the tubes of the third cylinder A³, while the vapor passes by the pipe
to the third cylinder A³, and so on through any number of effects. The condensed
water and incondensable vapors from the second cylinder pass by the pipe 2 to the
third cylinder A³. The separating chambers are arranged inside with baffle plates
for promotion of the deposition of the particles of liquid in a similar manner to
those described in the Specification of our Patent No. 11485, A.D. 1888, but instead
of forming the separating chambers between the evaporators, we now place them in
a column detached from the evaporators, but connected by the pipes or passages
already described. This arrangement is important, as it allows the apparatus to he
more conveniently taken in pieces for packing for transport.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In apparatus for evaporating, concentrating, or distilling, the forming of the
separating chambers in a column detached from the evaporators, and connected with
them by means of pipes for the liquor and vapor, substantially as described.
