COMPLETE SPECIFICATION.
An Improved Machine for Drying or Carbonizing Fabrics, Rags,
and Fibres.
I, GEORGE BARKER, of 77, Colmore Row, Birmingham, in the County of
Warwick, Consulting Engineer, do hereby declare the nature of the said invention,
as communicated to me from abroad by David Cole and Joshua Pedder, both
Manufacturers, and both of the Village of Doon, in the County of Waterloo, in
the Province of Ontario, Canada, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of the invention is to provide a machine which will perform its work
quickly and satisfactorily with the least possible amount of manual labor; and it
consists essentially of a double skin revolvable cylinder, a space being left between
the two skins into which steam is introduced through the trunion or trunions of the
cylinder, through which trunion or trunions the gas for carbonizing the rags, etc.,
contained within the cylinder is admitted, substantially as hereinafter more
particularly explained.
Figure 1 is a perspective view of my improved machine.
Figure 2 is a sectional elevation of the same.
My invention produces an improved machine for carbonizing or destroying
vegetable matter such as cotton and jute contained in rags and piece goods composed
of cotton and woollen, also for destroying burrs, seeds, straw, or other vegetable
matter contained in or mixed with woollen waste or other fibrous material.
A is a cylinder formed by an inner and outer skin a, and b, a space being left
between the two skins. At each end of the cylinder AI rivet or otherwise secure
a trunion B cach of which is suitably supported in a bearing box C. Each trunion
is bored out to receive a pipe D, which is arranged to communicate with the space
between the skins a and b but is closed from communicating with the interior of the
cylinder A.
A. stuffing, box E. is formed in the end of the trunion B so that the steam will not
leak out between the trunion B, and the pipe D.
F is a gas pipe leading from the gas retort to the interior of the cylinder A.
G is a stuffing box formed in the end of the pipe D, to prevent the gas escaping
from the cylinder A.
H is a steam pipe forming a connection between the steam boiler and the pipe D
which conducts the steam into the space between the skins a, and b.
I, is a gear wheel keyed or otherwise secured to the trunion, B.
J, is a worm secured to the shaft K and is carried in suitable bearings and has
suitable loose and driving pulleys as indicated.
L, is a door made in the cylinder A for the admission and discharge of the
material in or from the cylinder A.
M, is a series of fingers extending inwardly from and fixed to the inner skin a of
the cylinder.
A suitable platform should be erected so that the door L may be easily reached
for charging the cylinder A with the rags or other material to be carbonized.
When the said material is to be discharged the cylinder A is turned so that the
mouth of the door L will be upon the bottom side, when the material in the said
cylinder would naturally fall out or may be easily raked out without the necessity
of anyone entering the said cylinder.
The steam which is admitted through the pipes D, and H into the space between
the skins a and b by acting directly upon the inner skin a quickly heats the interior
of the cylinder A, and the steam which enters at one end of the cylinder A

page_text: through the pipes D'aud H escapes out of the other end of the cylinder through
corresponding pipes, and what is left of the burning gas which enters through the
pipe F at one end of the cylinder A escapes through a corresponding pipe located
at the opposite end of the said cylinder.
When the machine is to be used as a dryer the plugs N at one end of the
cylinder are removed, and the gas-pipe at the other end of the cylinder is connected
with an exhaust fan. The cylinder A is heated by steam in the same manner as
though the machine were used for carbonizing, and by the action of the exhaust fan
a constant current is drawn through the material into the cylinder, thereby quickly
drying the said material.
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 :-
1. An improved carbonizer consisting of a revolvable cylinder A having a space
formed around it between the inner skin a and the outer skin b, a steam pipe or
passage-way connecting the said space with a steam boiler and extending through
the trunion on which the cylinder is journalled, and a gas pipe or passage way
extending through the trunion and connecting the gas retort with the interior of
the cylinder substantially as and for the purpose specified.
2. An improved carbonizer consisting of a revolvable cylinder A having a space
formed around it between the inner skin a and the outer skin b a series of fingers M
connected to and extending inwardly from the inner skin a in combination with
trunions connected one at each end of the cylinder through which trunions a
passage-way leading to the space between the two skins of the cylinder is formed
and a passage-way leading to the interior of the cylinder substantially as and for
the purpose specified.
3. A cylinder having a steam space formed around it, immediately annexed to its
inner skin, and having holes formed in it at one end, in combination with a steam
pipe connecting the interior of the said space with the steam boiler, and a pipe
extending from the end of the cylinder opposite to that through which the holes
are made, and connecting the interior of the cylinder with an exhaust fan,
substantially as and for the purpose specified.
Dated this 10th day of March 1891.
GEORGE BARKER.
