This Invention relates to drying machines to be used in dressing fabrics, and
according to this Invention the machine consists of a drying cylinder constructed
of steel or other metal not acted on by the dressing of the fabrics to be dried, said
cylinder being heated interiorly by a circulation of steam, and of a strong endless
web (preferably of felt) which envelopes said cylinder for about ths its circum-
ference and extends a certain distance to the rear of the machine where it is carried
over guide rollers so as to participate in a continuous manner in the rotation of
the cylinder and remain at same time in contact therewith. The fabrics to be
dried pass through the machine and move in concert with the endless cloth applied
upon the heated cylinder and pass out dried at the point where contact ceases with
the cylinder.
By constructing the drying cylinder of sheet steel or other metal not acted on
by the dressing of the fabric, it is not necessary to constantly scrape and clean its
surface in order to avoid the deposit of any metallic compounds upon the fabric
and there is no danger of the cylinder becoming so reduced in thickness by the
continual dissolving away of its surface as to render it incapable of supporting with
safety the internal pressure of the steam used for heating it.

FINISHING FABRICS A communication from abroad by La Compagnie Générale
de teinturerie et apprêts "Systeme André Lyon," represented by Monsieur le
Vicomte de Gombert, administrateur Délégué of Paris, France.
This Invention relates to machines used in dressing fabrics and consisting of a
drying cylinder of copper heated interiorly by circulation of steam, and of a strong
endless cloth (usually of felt) which envelops said cylinder for about "ths of its
circumference and extends a certain distance to the rear of the machine where it is
carried over guide rollers so as to participate in a continuous tuunner in the rotation
of the cylinder and remain at same time in contact therewith. The fabrics to be
dressed pass through the munchine and move in concert with the endless cloth
applied upon the heated cylinder and pass out dried, at the point where contact
ceases with the cylinder
Hitherto these cylinders have been constructed of copper, and the dressing of the
fabrics subjected to the action of the machine is liable to act upon the metal of the
cylinder which requires to be continually scraped or cleaned in order to avoid the
deposit of coppery compounds upon the fabrics. This is objectionable both on
account of the extra work involved and also because of the danger that by the
continual dissolving away of the metallic surface the cylinder may be so reduced in
thickness as to no longer be capable of supporting with safety the internal pressure
of the steam used to heat it.
This Invention has for its object to avoid these objections and to so construct
the drying drum or cylinder that it will not be acted on by the dressing used for
the fabrics and be therefore capable of sustaining for an indefinite period the pressure
of the steam used for heating it. With this object the use of copper is abandoned
and steel used instead for the construction of the drying cylinder experience having
shown that steel is inalterable by the dressing commonly used, or any other metal
may be used which will attain the same result.. The metal may be used in the
form of sheets or in any other way according to the particular construction of the
drying cylinder to which the Invention is applied.
Having described the nature of the Invention and the manner of performing the
same I declare that what I claim as the Invention to be protected by the heroin-
before in part recited Letters Patent is.
In machines used in dressing fabrics in which a drying cylinder partially
enveloped by an endless cloth is employed the constructing said drying cylinder of
sheet or other steel or of other metal not liable to be acted on by the dressing as
and for the purpose specified.
In witness whereof I the said Alexander Melville Clark have hereunto set
my hand and seal this tenth day of October AD 1882.
