PROVISIONAL DIBITUATION.
A New or Improved Carbonizing and Drying Machine.
GEORGE TOLSON Engineer and JOHN EDWIN TOLSON Engineer Bradford
Road Dewsbury Yorkshire do hereby declare the nature of this invention to' be
as follows:-
This invention is in relation to a new or improved carbonizing, and drying
machine, and as, for its object the disintregation of vegetable matter from wool
rags and the like or, drying wool rags and the like, and consists of a revolving
or oscillating cylinder or chamber constructed with a duble shell, the shell inside
is perferated or wire work and is connected to an opening at one of the trunnions.
The outside shell is made air tight and is at a convienent distance from the
other shell and is connected to an opening at the other trunnion end. The
opening mentioned in connection with the perferated shell is to allow for the entry
of the gas or air as the case might be.
The material to be operated upon is placed in the inside.
The advantages of this machine is that the gas or air as the case might be,
can be more conviently blowen or sucked through the material as the con-
struction of the machine being such as the gas or air must enter through the,
trunnion in connection with the inner shell through the material into the
shell and make its escape through the other trunnion end.

We, GEORGE TOLSON and JOHN EDWIN TOLSON, Bradford Road, Dewsbury,
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 a new or improved machine for drying and carbonizing
fabrics, the object of the invention being to disintegrate or destroy the vegetable
matter contained in rags or wool and other like mixture.
In constructing a machine according to our invention we employ a double
revolving or oscillating shell or cylinder. The fabrics to be carbonized are first
heated by hot air after which the carbonizing gases are introduced.
Such being the nature and object of our invention, we will now proceed to
describe the same more fully, and for that purpose make reference to the
accompanying sheets of drawings, wherein Fig. 1 is a longitudinal section of our
improved machine, and Fig. 2 is cross section of same.
A represents a perforated or wire gauze cylinder or cage connected at one end
by bolts B and at the other end by stays C to an outer airtight cage or cylinder D.
This latter cylinder D is made with open ends, and provided with trunnions E
revolving upon rollers F and made to revolve by means of spur gearing G the

page_text: whole of the machine being enclosed in a chamber H. Before commencing to
carbonize or destroy the vegetable matter we first subject the fabrics to a high
temperature of hot air. To do this, we utilise heat from one or more furnaces, the
said heat passing through flues I through hot air chamber or box J and through the
trunnions E. The hot air thus introduced passes through the fabrics and through
perforations in the inner cylinder A entering into the annular space K being drawn
therethrough by means of the revolving fan L.
After the fabrics have been heated in the manner described, the valve M in
box J is closed so as to shut off the hot air. When carbonizing the fabric the
gases are made in the retort N and they pass through pipe O into the inner
revolving cage A. The gases thus introduced will impinge and act upon the fibres
so as to destroy the vegetable matter; the gases finally pass out through the
outlet end of the machine. The carbonizing gases may be shut off either by
ceasing to manufacture the gases, or by means of the damper P made in the
conduit pipe O.
By allowing the carbonizing gases to pass through the perforated cage A into
the annular space K, the fabrics are not scorched or browned, as would be the case
if the gases had not passages through which to escape.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is-
Firstly. In a machine for drying and carbonizing fabrics, the use therein of an
inner perforated cage A in combination with an airtight cage D and the annular
space K arranged and operating in the manner described and shewn in the
drawings.
Secondly. The combination and arrangement of parts forming our improved
carbonizing machine, constructed substantially as shewn and described.
