Improvements in and connected with Apparatus for the Production of
Acetic Acid from Acetates of Lime and Soda or from other Sub-
stances containing Acetic Acid.
I, WILLIAM HADFIELD BOWERS, of Brookfield Chemical Works, Napier Street,
Gorton, Manchester, in the County of Lancaster, Manufacturing Chemist, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with apparatus for
the production of acetic acid from acetates of lime and soda or from other
substances containing acetic acid.
According to my invention I construct my apparatus so as to have a number
of parallel flues extending longitudinally along and within the same and lying
side by side or in tiers or otherwise arranged as may be found most convenient.
The space immediately above adjoining or surrounded by the said flues forms
the chamber in which the material is treated for distillation.
It has one or more outlets connected by means of a pipe or pipes to the
necessary condensers whereby the vapours arising from the treatment of the
material are conveyed to the latter.
The said chamber has also an inlet for the supply of the material to be
treated and an outlet for the discharge of the spent or treated material, which
inlets and outlets may be arranged in convenient positions.
The said chamber is divided into any convenient number of equal spaces by
means of ribs running parallel to the sides of the apparatus and these ribs
may be of any desired height provided they do not obstruct the due distribution
of heat in the chamber.
An endless chain is by means of sprocket wheels worked along and in a
plane parallel to the floor of the chamber through each of the spaces so formed
in the chamber. The said chain is constructed with bars or scrapers fixed
thereto on each side at convenient intervals. These bars or scrapers are also
placed and work in the same plane as and along the floor of the chamber and
they are of such length as to reach to but at the same time work free of the
ribs placed and fixed in the chamber as before indicated.
By these means the material to be treated upon is swept or dragged through
the several spaces of the chamber until it reaches the outlet and is discharged,
whilst the vapour arising therefrom is allowed to continuously escape from
the said chamber to the said condensers.

Improvements in and connected with Apparatus for the Production of
Acetic Acid from Acetates of Lime and Soda or from other Sub-
stances containing Acetic Acid.
I, WILLIAM HADFIELD BOWERS, of Brookfield Chemical Works, Napier Street,
Gorton, Manchester, in the County of Lancaster, Manufacturing 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 improvements in and connected with apparatus for
the production of acetic acid from acetates of lime and soda or from other
substances containing acetic acid.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view, Fig. 2 a plan with cover removed, Fig. a cross section,
and rig. 4 an end view of my improved apparatus for the production of acetic
acid from acetates of lime and soda or from other substances containing acetic
acid.
In carrying out this invention and referring to the figures generally I con-
struct my improved apparatus so as to have a number of parallel flues a ex-
tending longitudinally along and within the same, and lying side by side or
in tiers or otherwise arranged as may be found most convenient.
The space immediately above adjoining or surrounded by the said flues,
forms the chamber in which the material is treated for distillation.
The said chamber has also one or more outlets c, in the present instance three,
formed in the top of the apparatus connected by means of a pipe or pipes (not
shown) to the necessary condensers whereby the vapours arising from the treat-
ment of the material are conveyed to the latter.
The said chamber has an inlet d for the supply of the material to be treated
and an outlet e for the discharge of the spent or treated material, which inlet
and outlet in the present instance are formed in the top and bottom of the
apparatus respectively.
The said chamber is divided into any convenient number of equal spaces or
compartments, by means of ribs f running parallel to the sides of the apparatus
and these ribs may be of any desired height provided they do not obstruct
the due distribution of heat in the chamber.
An endless chain y, is by means of a sprocket and guide wheels h, h, respec-
tively worked along and in a plane parallel to the floor of the chamber through
each of the spaces, so formed in the chamber. The said chain is constructed
with bars or scrapers i fixed thereto on each side at convenient intervals. These
bars or scrapers are also placed and work in the sanie plane as and along the
floor of the chamber and they are of such length as to reach to, but at the
same time work free of the ribs f placed and fixed in the chamber as before
indicated.
By these means the material to be treated upon is swept or dragged through
the several spaces of the chamber until it reaches the outlete and is dis-
charged, whilst the vapour arising therefrom is allowed to continuously escape
from the said chamber to the said condensers as will be readily understood."
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
I claim is
1st. In an apparatus for the production of acetic acid from acetates of lime

page_text: and soda or from other substances containing acetic acid, a hot air chamber b
having a material supply inlet and discharge outlet and one or more vapour
outlets d, e, e, respectively in combination with an endless chain y carrying
at its underside scrapers, which by the said chain are moved along and in
contact with the floor of the hot air chamber b, the said vapour outlets being
connected to condensers, all substantially as set forth.
2nd. In combination with the travelling scrapers specified in the preceding
claim, ribs f arranged on the floor of the hot air chamber b between the ends of
the said scrapers, adapted to form spaces or compartments b₁ for the said
scrapers to move in, all substantially as and for the purpose set forth.
