Improvements in Apparatus for Drying or Carbonizing Fabrics
Composed of Animal and Vegetable Fibres, Wool, Silk, Cotton,
Flax, Rags, or other like Fibrous Substances.
We JOSEPH WALKER of No. 8 South Street Savile Town Dewsbury in the County
of York Mechanical Engineer and WALTER BROWN of Church Street in Dewsbury
aforesaid Solicitor do hereby declare the nature of this invention to be as follows:-
This invention refers to means to be employed for drying or carbonizing fabrics
composed of animal and vegetable fibres wool silk cotton flax rags or other like fibrous
substances.
In carrying out this invention we employ a house or casing and place therein a level
perforated or grated floor. This floor is provided with joints and horizontal axis and
is caused to become undulated or wavy and level alternately by means of ordinary
mechanical contrivances or other well known mechanical appliances.
The house or casing is provided with suitable inlet and outlet doors and the fabrics
or fibres to be operated upon are placed and spread on the perforated or grated floor,
the carbonizing gases are afterwards introduced into the house or case and the perforated
or grated floor is set in motion thereby shaking and dividing the fabrics or fibres and
allowing the gases to penetrate the whole of them. In order to assist the escape of
the gases from the house or case a steam pipe is introduced into the top thereof through
which the gases escape by which means an updraught is produced which greatly
facilitates the exit of the gases from the house or case.
For the purposes of drying, hot air is generated under the perforated or grated floor
and passes through the gratings or perforations and thereby intermingles with the
fabrics or fibres whereby they become thoroughly and quickly dried.

Improvements in Apparatus for Drying or Carbonizing Fabrics
Composed of Animal and Vegetable Fibres, Wool, Silk, Cotton,
Flax, Rags, or other like Fibrous Substances.
We JOSEPH WALKER of 8 South Street Savile Town Dewsbury in the County of
York Mechanical Engineer and WALTER BROWN of Church Street in Dewsbury
aforesaid Solicitor 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 refers to means to be employed for drying or carbonizing wool silk
cotton flax rags or other like fibrous substances.
In carrying out this invention we employ a casing and place therein a level
perforated or grated floor. This floor is provided with joints and horizontal axis and
is caused to become undulated or wavy and level alternately by means of ordinary
mechanical contrivances or other well known mechanical appliances.
The casing is provided with suitable inlet and outlet doors and the fabrics or fibres
to be operated upon are placed and spread on the perforated or grated floor the
carbonizing gases are afterwards introduced into the case and the perforated or grated
floor is set in motion thereby shaking and dividing the fabrics and allowing the gases
to penetrate the whole of them. In order to assist the escape of the gases from the
case a steam pipe is introduced into the top of the case through which the gases

the gases from the case.
For the purposes of drying, hot air is generated under the perforated or grated
floor and passes through the gratings or perforations and thereby intermingles with
the fabrics whereby they become thoroughly and quickly dried.
In order that our invention may be more fully understood we herein make reference
to the accompanying sheets of drawings illustrative thereof.
Figure 1 is an end elevatiom of the casing A, showing the inlet and outlet doors B
of the undulating or wavy floor or grating. E are rocking levers, P is a pipe or
chimney fixed on the top of the casing through which the spent gases or vapour escapes.
Such pipe or chimney being provided with an ordinary wing valve for opening and
closing. There is also a steam jet fixed in the pipe or chimney to increase the
updraught so as to assist the escape of the spent gases or vapour.
Figure 2 is an end elevation of the casing showing the inlet and outlet doors C of
the casing.
Figure 3 shows the perforated floor or grating D in a level or flat position on which
the fabrics are placed for carbonizing or drying, which is caused to become wavy or
undulating by the rocking levers E and the main shaft F. This floor or grating is
divided into three or more parts and the parts are joined together by hinges or joints.
Each part of the floor is bolted or fastened to a separate pair of rocking beams. The
floor when level is raised some distance above the bottom of the casing.
Figure shows G the rocking beams on which the perforated floor or grating
marked D in Figure 3 is bolted or fastened. F is the main shaft to which the central
rocking beams are secured or fastened which main shaft when set in motion depresses
or lowers one end of the central rocking beams and also lowers or depresses the end
of the other rocking beams that are attached to the depressed end of the central
rocking beams as shown by the dotted lines in Figure 5 and at the same time raises
the other end of the central rocking beams and also raises those ends of the other
rocking beams that are attached to the raised ends of the central rocking beams as
shown in the dotted lines of Figure 5. The end rocking beams are supported by
rocking levers E which rocking levers are fastened or secured to the sides of the
casing at some distance from the ground by gudgeons or pivots J. H are round bars
running through the rocking beams and rocking levers thereby supporting the
perforated floor or grating. The rocking beams are also connected to each other by
similar round bars passing through them as in male and female joints or hinges. The
main shaft F is connected with and worked by the lever I the motion of which is got
by a connecting rod K shown in Figure 6 attached to lever I and the other end of
connecting rod is attached to pin in wheel as shown in Figure 6 or any other well
known mechanical appliance.
Figure 5 is a longitudinal section or side elevation of undulating floor or grating.
L shows the sides of the perforated floor or grating. Q is a rod connected to wing
valve for opening and closing the same.
Figure 6 is a longitudinal elevation of the outside of the casing with lever I and
connecting rod K attached thereto.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The combined arrangement of machinery for carbonizing and drying purposes
substantially as described in Figures 3, 4 and 5.
