PROVISIONAL SPECIFICATION.
Apparatus for Recovering Acetate Liquor from White Lead and
Washing the White Lead.
I, GUSTAV BISCHOF, of 11, Victoria Street, Westminster, in the County of
London, Professor and Analytical Chemist, do hereby declare the nature of this
invention to be as follows:-
This invention relates to apparatus whereby the acetate liquor is recovered
from white lead in pasty condition, and the paste is afterwards washed.
For this purpose the paste is passed between a pair of rollers by which it is
pressed into thin flakes, the acetate liquor being squeezed out of the paste. The
flakes and liquor are received from the rollers on an inclined travelling band
by which the flakes are carried upwards while the liquor runs down the band to
receptacles where it is collected for subsequent use.
The flakes are delivered from the travelling band to another pair of rollers
having water sprayed upon them as they enter between the rollers.
They are squeezed with the water by which any residue of acetate liquor is
washed out, and they are received on another inclined travelling band which
carries up the flakes to trucks or conveyors, while the water runs down the band.
Dated this 23rd day of December 1897.

Apparatus for Recovering Acetate Liquor from White Lead and
Washing the White Lead.
1, GUSTAV BISCHOF, of 11, Victoria Street, Westminster, in the County of
London, Professor and Analytical Chemist, 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 relates to apparatus whereby the acetate liquor is recovered
from white lead in pasty condition and the paste is afterwards washed, as I
shall describe referring to the accompanying drawing, which is a side view of
the apparatus.
H is a feed hopper by which the pasty lead carbonate mixed with acetic liquors
is fed to a pair of rollers I which are pressed together by a loaded lever i.
The material after passing through between the rollers, which are provided

page_text: with scrapers j, drops in the form of thin flakes and liquid on to an endless apron K
of suitable fabric which carries the solid matter upwards while the liquid
draining from it flows down the apron to a receptacle which may be placed below.
The solid pieces are delivered from the apron K to a second pair of rollers I¹
where the material undergoes a second squeezing and is washed by water dropped
on it, the flakes and liquor being received on a second apron K' on which the solid
material is carried upwards and from which it is delivered into a suitable recep-
tacle while the liquor flows downwards.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:-
Apparatus for squeezing and washing white lead paste constructed and operat-
ing substantially as described with reference to the drawing.
Dated this 15th day of September 1898.
