IMPROVEMENTS IN THE MANUFACTURE OF LEATHER CLOTH, OIL BAIZE, AND OTHER SIMILAR MATERIALS
Year: 1878

page_text: LETTERS PATENT to George Hadfield, of Manchester, in the County of Lancaster,
for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF LEATHER
CLOTH, OIL BAIZE, AND OTHER SIMILAR MATERIALS."
Sealed the 10th September 1878, and dated the 11th March 1878.
PROVISIONAL SPECIFICATION left by the said George Hadfield at the
Office of the Commissioners of Patents on the 11th March 1878.
GEORGE HADFIELD, of Manchester, in the County of Lancaster. "IMPROVEMENTS
IN THE MANUFACTURE OF LEATHER CLOTH, OIL BAIZE, AND OTHER SIMILAR
MATERIALS."
The object of this Invention is to give an impermeable and elastic coating or
covering to one face of the cloth, baize, or other fabric, without soiling the other
side or back, so as to prepare it to receive the usual surface coating, and to prevent
the oil, spirit, or other liquid employed from penetrating to and discoloring the
back.
The coating material which I employ for this purpose is thickened or oxydised
linseed oil, made (by preference) according to the Specification of Letters Patent
granted to me, and bearing date September 19th 1877, No. 3521, or it may be
thickened or oxydized in any other suitable manner. My improved method of
applying this preparatory coating is to apply it to the surface hot, and without
thinning it with spirit, or otherwise by means of a revolving roller well known to
calico printers, and called a "pin pad" roller. By means of a roller of this descrip-
tion, a coating of the oil can be laid on whilst it is in a very thick state, and it will
not then penetrate through the cloth to the surface.
Another way in which I propose to apply this thickened oil is to run a conţinuous
length of brown or other paper through a trough in which the oil is kept hot, and
then when the paper is thus coated or saturated with the thickened oil, and before
it is dry, I pass it between rollers which press it into contact with the-cloth or
D

page_text: baize. When this preparatory coating (either with or without the paper) has
become dried, I then proceed to finish this prepared face of the cloth or baize with
the ordinary materials for producing the appearance of leather or oil baize, and it
will be found that by reason of the impermeable nature of the first preparation, the
materials employed for producing the leather or other surface required, will not 5
penetrate to the back of the cloth, which will retain its original appearance, and
will not become soiled nor shrunk during the process.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Hadfield in the Great Seal Patent Office on the 11th September
1878.

The object of this Invention is to give an impermeable and elastic coating or

The coating material which I employ for this purpose is thickened or oxydised

description, a coating of the oil can be laid on whilst it is in a very thick state, and
it will not then penetrate through the cloth to the surface.
The use of this roller also prevents the narrowing of the cloth which has always
hitherto taken place, and keeps it much more even and smooth.
Another way in which I propose to apply this thickened oil is to run a continuous
length of brown or other paper through a trough in which the oil is kept hot, and
then when the paper is thus coated or saturated with the thickened oil, and before
it is dry, I pass it between rollers which press it into contact with the cloth or

will not become soiled nor shrink during the process.

page_text: . Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I wish it to be understood that I claim as my Invention,―
First. The use or application of the oxydized or thickened oil by means of a
"pin pad" roller, in the manner and for the purposes above described,
And, Secondly, I claim the use of brown or other paper as a vehicle for the
oxydized or thickened oil in the manner herein-before described.
In witness whereof, I, the said George Hadfield, have hereunto set my hand
and seal, this Ninth day of September, in the year of our Lord One
thousand eight hundred and seventy-eight.
