PROVISIONAL SPECIFICATION.
Improvements in Carbonizing Machines for Wool, Rags, and the like.
JOHN EDWIN TOLSON 62 Hartley Street Dewsbury Yorkshire Engineer do hereby
declare the nature of this invention to be as follows:-
This invention is in relation to improvements in carbonizing machines and consists
of a shell or caseing placed at a suitable distance from the existing shell of the
present carbonizing machines and so arranged that when the machine rotates it will
cause a current of air to pass between the said caseings. The proposed shell or case
is provided with suitable slits or openings so that when the machine rotates it will
cause the above mentioned current of air.
The advantages I claim for this improvement is, that, in the present machines the
heated air acts directly and unequaly on the caseing and causes the materials that
are operated upon to become singed or burned in a slight degree, but, by the adaption
of this improvement the air is equaly distributed and singeing or burning is
prevented.

COMPLETE SPECIFICATION.
Improvements in Carbonizing Machines for Wool, Rags, and the like.
I, JOHN EDWIN TOLSON, late of 62 Hartley Street, Dewsbury, in the County of
York, and now of Meadow House, Dewsbury aforesaid, Carbonizing Engineer, 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 machines employed for carbonizing rags
and the like. In machines of this kind there is employed a rotating metal cylinder
or shell in which the rags to be carbonized are placed, and when in operation
heated air acts directly and unequally upon the cylinder, and the latter becomes
overheated in places, and the rags in contact with the interior of the cylinder are
liable to be scorched or burnt. The object of the present invention is to obviate
this defect by causing the heated air or gases to act uniformly over the whole
surface of the cylinder or shell, and this result is obtained by arranging and fixing
to and around the cylinder or shell an outer concentric, shell with longitudinal slits
or openings therein, and as the cylinder revolves, the air passes through the openings
or slots and is equally and uniformly distributed over the whole surface of the inner
cylinder or shell.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which :-
Fig. 1 is a side elevation of a carbonizing machine maie in accordance with this

page_text: invention, part of the brick work covering the cylinder or shell being removed in
order to shew its construction.
Fig. 2 is a sectional end view of the inner and outer cylinder or shell.
According to this invention the main cylinder or shell 1 is preferably polygonal
(see Fig. 2) and to each side of the main cylinder 1 and at a few inches distance
from same we fix a plate 2 by means of bolts and bushes, rivets, or otherwise.
There is a longitudinal slit or opening 3 left between the adjacent edges of the
plates 2; and as the cylinder 1 and its outer shell or covering 2 rotate, the air passes
through the slots or openings 3, 3 and circulates about the cylinder 1 between the
latter and the several plates 2. 2.
In practice it is found that when using this improved construction of carbonizing
cylinder, the rags under operation or being carbonized, are not singed or scorched,
and the heated air or gases being uniformly spread over the whole surface, better
results are obtainable and more work can be done.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In carbonizing machines an inner cylinder 1 surrounded by an outer or concentric
shell in which are a series of slots or openings as and for the purpose herein described
and substantially as illustrated by the accompanying drawings.
