Improvements in Apparatus for Treating Fabrics, Paper, and other
Materials with Gases, Steam, or Hot Air.
I, EMILE REMY, of Mülhausen, Elsass, German Empire, Engineer, do hereby declare
the nature of this invention to be as follows:-
―
This invention relates to improvements in apparatus in which fabrics, paper, yarns
and other materials can be exposed within a comparatively small space during a
certain period of time, and with as great a surface or area as possible to the action or
treatment of gases, steam or hot air, and in which the material under treatment can
enter and leave the apparatus in a continuous and automatic manner.
The improvements consist in improved devices by which the fabric, paper, yarn, etc.
(hereinafter referred to as material) entering the apparatus, is automatically shaped
into long folds that hang down side by side, whereby such material during its travel
through the apparatus will offer or expose a large surface to the action of gases, steam
or hot air within the apparatus. The apparatus with these improved devices may be
entirely or partly closed openings being however provided for the material under
treatment to enter and leave the apparatus and also for the means used to actuate
the parts within the apparatus.
Fig. 1 is a longitudinal vertical section;
Fig. 2 a cross section; and Fig. 3 a horizontal section of the apparatus enclosed
by side and end walls W and cover V.
Within the apparatus are vertical uprights M that carry the moving and guiding
mechanism. This mechanism comprises eight chain wheels R divided into two sets,
each set of four wheels lying in a common vertical plane and each set being sur-
rounded by an endless chain P. The two chains each receive a travelling motion from
one or more of their chain wheels R. To the links of the chains P P are attached, at
suitable distances apart, short arms or levers A each capable of turning about a centre.
Each two of these arms or levers A, constituting a set and in corresponding positions
on the two chains are connected together by a bar, rod or roller B. When the chains
are travelling each set of two arms A thus connected by a rod B will, at the entrance
end of the apparatus hang in a downward position and in a contrary direction to that
in which the chains are travelling.
At a suitable position and near to that point at which the material to be treated is
fed into the apparatus by rotating feeding rollers D D is mounted a set of turnstiles C,
capable of rotating at a higher speed than the travelling speed of the endless
chains P P. If now the material to be treated enters the apparatus between the
endless chains P in a downward vertical direction, the revolving turnstiles C will take
underneath the next rod B arriving with the travelling chains, and will lift such rod
with its two arms A and will turn the rod and arms over in the opposite direction,
that is, in a forward direction, so that the arms are then in a position corresponding
with the travelling direction of the chains. During the lifting of the rod B the latter
has been brought underneath the entering material, which latter in continuing its
downward travel will form a vertically hanging fold or plait, until the turnstiles C
have lifted the next rod B and brought the same underneath the entering material so
as to form a second fold or plait similar to the first. As the endless chains con-
tinuously travel onward and the turnstiles C after the turning over of a rod B are
somewhat retarded in their rotation there will always be an appropriate period of time
between the actions of the turnstiles on two successive rods B for the automatic
formation of the material into folds or plaits one after the other in the manner
described. The length of such folds or plaits may be regulated at will. This action
of turning the rods B over from a rearward into a forward position is constantly

through the greater part of the space or length of the apparatus in long downwardly
hanging folds or plaits until it arrives near the end of the uppermost portion of the
length of the chains where the material is conducted over guide rollers E and either
directly leaves the apparatus, or is guided downwardly and then horizontally below
the endless chains as shewn, back to the entrance side of the apparatus. This latter
course is most advantageous on account of the material being further subjected to the
influence of the gas, steam or hot air.
The driving of the mechanism will be readily understood from the drawings and
does not require any further description.

rods B are turned over by the turnstiles C as shewn to an enlarged scale.
The apparatus may be provided with apertures for the exit of moisture and may
be connected by these apertures with ventilators or exhausters for the expulsion of
moist air etc.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Treating Fabrics, Paper, and other
Materials with Gases, Steam, or Hot Air.
I, EMILE REMY, of Mülhausen, Elsass, German Empire, 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 apparatus in which fabrics, paper, yarns
and other materials can be exposed within a comparatively small space, during a
certain period of time, and with as great a surface or area as possible to the action
or treatment of gases, steam, or hot air, the construction being such that the
material under treatment can enter and leave the apparatus in a continuous and
automatic manner.
The apparatus comprises a chamber within which are devices by which the fabric,
paper, yarn etc. (hereinafter referred to as material) entering the chamber, is
automatically shaped into long folds that hang down, side by side, so that such
material during its travel through the chamber will offer or expose a large surface to
the action of gases, steam or hot air, therein. The chamber with these improved
devices may be entirely or partly closed, openings being however provided for the
entrance and exit of the material under treatment and for the passage of the means
used to actuate the parts within the chamber.
Referring to the drawings filed with my Provisional Specification,
Fig. 1 is a longitudinal vertical section ;
Fig. 2 a cross section; and
Fig. 3 a sectional plan of apparatus according to this invention.
Within a chamber having side and end walls W and a cover V, are vertical
uprights M that carry the moving and guiding mechanism. This mechanism com-
prises eight chain wheels R divided into two sets each consisting of four wheels
lying in a common vertical plane and surrounded by an endless chain P. The two
chains each receive a travelling motion from one or more of their chain wheels R.
To the links of the chains P P are attached, at suitable distances apart, short arms
or levers A each capable of turning about a centre. Each two of these arms A
constituting a set and in corresponding positions on the two chains, are connected
together by a bar, rod, or roller B. When the chains are travelling, each set of two
arms A thus connected by a rod B will at the entrance end of the apparatus, hang
in a downward position, and in a contrary direction to that in which the chains are
travelling. At a suitable position and near to that point at which the material to be
treated is fed into the apparatus by rotating feed rollers I) D, is mounted a set of

page_text: turnstiles C, capable of rotating at a higher speed than the travelling speed of the
endless chains P P. If now the material to be treated enters the apparatus between
the endless chains P in a downward vertical direction as indicated by dotted lines,
the revolving turnstiles C will take underneath the next rod B arriving with the
travelling chains, and will lift such rod with its two arms A and will turn the rod
and arms over in the opposite direction, that is, in a forward direction, so that the
arms are then in a position corresponding with the travelling direction of the chains.
By the lifting of the rod B the latter is brought against and underneath the entering
material, which in continuing its downward travel will form a vertically hanging
fold, until the turnstiles C lift the next rod B and bring the same underneath the
entering material so as to form a second fold similar to the first. As the endless
chains continuously travel onward and the turnstiles C after the turning over of a
rod B are somewhat retarded in their rotation, there will always be an appropriate
period between the action of the turnstiles on two successive rods B, for the auto-
matic formation of the material into folds one after the other in the manner
described. The length of such folds can be regulated at will. This action of
turning the rods B over from a rearward into a forward position is constantly
repeated, so that the materia! under treatment is caused to travel with the chains P
through the greater part of the space or length of the chamber in long downwardly
hanging folds until it arrives near the end of the uppermost portion of the length of
the chains where the material is conducted over guide rollers E and either directly
leaves the apparatus, or is guided downwardly and then horizontally below the end-
less chains P as shewn, back to the entrance side of the apparatus. This latter
course is most advantageous because the material will remain longer in the chamber
and will consequently be further subjected to the influence of the gas, steam, or hot
air therein.
The driving of the mechanism will be readily understood from the drawings and
will not require any further description.
In Figs.
and 5 that part of the apparatus at which the material enters and the
rods B are turned over from their backward to their forward positions by the turn-
stiles (, is shewn to a larger scale than in Figs. 1 and 2.
The chamber may be provided with apertures for the exit of moisture, and it may
be placed in communication by these apertures with ventilators or exhausters for the
renioval of moist air, etc.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
An apparatus for treating fabrics, paper, yarns or other material by gases, steam
or hot air, in which the passage of the material through a chamber wherein it is to
be treated, is caused by two travelling endless chains P, arranged parallel to each
other and provided with arms or levers (A) each adapted to turn about a centre,
each two of these arms or levers, constituting a set, and in corresponding positions
on the two chains, being connected by a bar, rod or roller (B) that is capable of being
turned over by means of one or more turnstiles (C) located near the entrance to
the chamber and operating in such a manner, that the said rods, bars or rollers are
brought in succession underneath the entering material and cause the same to be
formed into long folds the material being afterwards drawn or straightened out at
the opposite end of the chamber, substantially as hereinbefore described.
