IMPROVEMENTS IN LEATHER ROLLING MACHINERY
Year: 1876

page_text: LETTERS PATENT to William Lawies Jackson, of Leeds, in the County of York,
for the Invention of "IMPROVEMENTS IN LEATHER ROLLING MACHINERY."
PROVISIONAL SPECIFICATION left by the said William Lawies Jackson at
the Office of the Commissioners of Patents on the 10th February 1876.
WILLIAM LAWIES JACKSON, of Leeds, in the County of York. "IMPROVEMENTS
IN LEATHER ROLLING MACHINERY."
My Invention has reference to leather rolling machines, and the results of my
Invention are, the machine does its work in less time, glazes the surface better,
producing at the same time a better face or finish, and makes the leather much
firmer than machines of ordinary construction.
This Invention is applicable to machines employed in rolling "sole" leathers and
other leather requiring solidity and facing.
Several descriptions of machines are used for rolling leather, as for instance,
machines with one roller weighted and caused to move backwards and forwards
over a table.
Other machines are provided with two-rollers between which the leather is passed
for rolling or pressing purposes; hitherto cold rollers have been employed on the
above-mentioned machines.
In my Invention where double rollers are employed I cause one or both of them
to be heated by hot water, steam, or other equivalents.
When single rollers are employed I cause either the roller to be heated or the
table on which the leather is placed, or when preferred both the roller and table
may be heated.
The rollers are by preference made hollow and heated by means of a supply of
hot water or steam passing into or through the interior thereof. The plate may
also be made hollow and heated by hot water, steam, or gas. Any other con-
venient known means may be employed for heating the rollers and plate.

WILLIAM LAWIES JACKSON, of Leeds, in the County of York. "IMPROVEMENTS IN
LEATHER ROLLING MACHINERY."
My Invention has reference to leather rolling machines, and the results of my
Invention are, that the machine does its work in less time and glazes the surface
better, producing at the same time a better face or finish, and making the leather
much firmer than machines of ordinary construction.
This Invention is applicable to machines employed in rolling "sole" leather and
other leather requiring solidity and facing.
Several descriptions of machines are now used for rolling leather, as for instance
machines with one roller weighted and caused to move backwards and forwards
over a table.
Other machines are provided with two rollers between which the leather is
passed for rolling or pressing purposes; hitherto cold rollers have been employed on
the above-mentioned machines.
According to my Invention where double rollers are employed I cause one or
both of them to be heated by hot water, steam, or other equivalent.
When single rollers are employed I cause either the roller to be heated or the
table on which the leather is placed, or when preferred both the roller and table
may be heated.
And in order that the mode in which my Invention may be carried out may be
more completely understood, reference is given to the accompanying Sheet of
Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a front elevation; Figure 2, a side elevation; Figure 3, a
part plan, and Figure 4, an enlarged detail.
In the annexed Drawings I have shown the application of my Invention to
leather rolling machines of ordinary construction, that is to say, machines having
an upper roller a, and a lower roller b, the upper roller being weighted to give the
required pressure as shewn at c by means of lever and weight.
The mode of applying my Invention is as follows-a is the top roller; at a
suitable distance therefrom I fix a perforated tube d, which tube d is supplied
with gas which may be ignited at the perforations e, as shewn clearly at Figs. 3
and 4. The flame coming in contact with the roller a causes the roller a to be
heated, which heat can be increased or reduced by regulating the size of the flame.
In order to render the heat more intense and to prevent the rollers being smoked,
I admit an amount of common air at the opening y. The amount of air may be
regulated by means of a cock. The air and gas are thus made to commingle before
coming to the point of ignition.
When preferred both top and bottom rollers may be heated by gas preferably in
the manner here shewn, or by the admission into their interiors of hot water or
steam.
I would here remark that it will be readily understood by all competent persons
that the rollers of any ordinary rolling machine can be heated by the admission of
hot water or steam into their interior, or by a flame substantially as herein
described; also the table may be heated either by the application of a flame or by
hot water or steam.
Having now described the nature of my Invention, and shewn by Drawings how
the same may be carried into practice, I would have it understood that I do not
limit myself to the exact details or contiguration of the various parts I have
explained and shewn, as the same may of course be varied or modified without in

page_text: any way departing from the nature of my Invention; but what I do claim and
desire to be secured to me by Letters Patent is,―
First. The application of heated roller or rollers for the purpose of rolling "sole"
leathers and other leathers requiring solidity and facing, substantially as herein set
forth.
Second. The application of heated tables to leather rolling machines, substantially.
as and for the purposes herein set forth.
In witness whereof, I, the said William Lawies Jackson, have hereunto set
my hand and seal, this Second day of August, in the year of our Lord
One thousand eight hundred and seventy-six.
