Year: 1862

page_text: LETTERS PATENT to Charles Sanderson, of Sheffield, in the County of
York, Steel Manufacturer, for the Invention of "AN IMPROVED MODE OF
MANUFACTURING BANDS FOR DRIVING MACHINERY, LIPTING WEIGHTS, AND
OTHER ANALOGOUS PURPOSES."
Sealed the 2nd June 1863, and dated the 8th December 1862.
PROVISIONAL SPECIFICATION left by the said Charles Sanderson at
the Office of the Commissioners of Patents, with his Petition, on the
8th December 1862.
I, CHARLES SANDERSON, of Sheffield, in the County of York, Steel Manu-
facturer, do hereby declare the nature of the said Invention for "AN
IMPROVED MODE OF MANUFACTURING BANDS FOR DRIVING MACHINERY, LIFTING
WEIGHTS, AND OTHER ANALOGOUS PURPOSES," to be as follows:-
My Invention of "An Improved Mode of Manufacturing Bands for Driving
Machinery, Lifting Weights, and other Analogous Purposes," consists in
making these articles of thin sheet steel cut to the width of the intended
driving or lifting band, and coated or protected in a peculiar manner by india-.
rubber so as to preserve the metal from oxidation.
In carrying out my Invention the sheet steel, cut to the proper width and
length, is first well cleaned on both sides by acids or otherwise, in order to
remove any oxide therefrom. It is then coated by the electro-plating process:

page_text: with brass, after which the metal band is covered with and entirely enclosed
with a sheet of india-rubber which is vulcanized thereon, when it will be
found that the rubber will have such an affinity for the brass covering that it
will adhere firmly, and cannot easily be detached therefrom. Bands of great
strength, such as are required for lifting heavy weights in coal mines, may be
made by combining together two, three, or more thin bands or strips of steel
coated and covered in the manner above set forth, interposing between all the
metal surfaces a layer of vulcanized india-rubber. The india-rubber covering
will not only protect the metal from oxidation, but will materially assist in
causing the band to hold tight on the driving or lifting pullies.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Sanderson in the Great Seal Patent Office on the
8th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
SANDERSON, of Sheffield,. in the County of York, Steel Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Sanderson, Her special license that I, the said Charles Sanderson, my
executors, administrators, and assigns, or such others as I, the said Charles
Sanderson, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,. and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED MODE OF MANUFAC-
TURING BANDS FOR DRIVING MACHINERY, LIFTING WEIGHTS, AND OTHER ANALOGOUS
PURPOSES," upon the condition (amongst others) that I, the said Charles
Sanderson, by an instrument in writing under my hand and seal, should par-
ticularly describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Sanderson, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say):
:-
My Invention of "An Improved Mode of Manufacturing Bands for Driving
Machinery, Lifting Weights, and other analogous Purposes," consists in
making these articles of thin sheet steel or other metal cut to the width of the
intended driving or lifting band, and coated or protected in a peculiar manner
by india-rubber so as to preserve the metal from oxydation.
In carrying out my Invention the sheet steel or other metal cut to the
proper width and length, is first well cleaned on both sides by acids or otherwise,
in order to remove any oxide therefrom. It is then coated by the electro-
plating process with brass, after which the metal band is covered with and
entirely enclosed with a sheet of india-rubber which is vulcanized thereon,
when it will be found that the rubber will have such an affinity for the brass
covering that it will adhere firmly thereto, and cannot easily be detached.
Bands of great strength, such as are required for lifting heavy weights in coal
mines, may be made by combining together two, three, or more thin bands or
strips of steel or other metal, coated and covered in the manner above set forth;
interposing between all the metal surfaces a layer of vulcanized india-rubber.
The india-rubber covering will not only protect the metal from oxydation, but
will materially assist in causing the band to hold tight on the driving or lifting
pullies.
In adapting my Invention to the manufacture of bands of greater length
than can be made from one strip or length of steel or other metal, any number
of lengths of sheet metal (according to the total length of the band to be pro-
duced) may be combined and rivetted, or otherwise.connected together in such
a manner as to break joint, and produce a band of equal strength throughout.
In the accompanying Drawing Fig. 1' is a plan view, and Fig. 2 a sectional
view of part of a long band formed of two thicknesses of sheet steel or other
metal with a coating or layer of rubber between them, and shewing also the
mode of connecting or securing the sheets of steel or other metal together so
as to form a strong band. It will however be understood that more than two
thicknesses of steel or other metal may be employed if desired. It will be
seen that the band shewn in the Drawing is composed of two thicknesses of
sheet metal a and a', a part of the outer coating of india-rubber having been
removed to shew the metal bands within. It will be seen that the ends
of the upper sheets of metal a, a, are brought together, and then rivetted to
the under sheet a', a layer of rubber having been previously placed between
them; Fig. 3 represents a sectional view of another mode of connecting the

page_text: sheets of steel or other metal together. In this instance the ends are bent
into the form of a hook, so as to catch the one under the other as shewn in
the Drawing, and when all the parts are well cemented together by the india-
It has been-
rubber, this will form a very secure and yet simple connection.
already stated that the surfaces of the sheets of steel or other metal, after
being properly cleaned, are coated with brass (see the magnified sectional
view, Fig. 4) it therefore only remains to state that the rubber compound is to
be applied as a coating or covering of the steel, as shewn in the Drawing, and
then the article thus prepared is to be submitted to the vulcanizing process in
the ordinary manner.
When short bands, that can be made from one length of steel or other
metal, manufactured, as before stated, without joints, are required, it will only
be necessary to connect together the two ends of a band of suitable length by
means of rivetting or otherwise, so as to form an endless band.
Having now, described my Invention of "An Improved Mode of Manufac-
turing Bands for Driving Machinery, Lifting Weights, and other analogous
Purposes," and having explained the manner of carrying the same into effect,
I claim as the Invention secured to me by Letters Patent as afore said, the mode
above described of combining sheet steel or other suitable metal and vulcanized
india-rubber for the manufacture of bands for the purposes herein set forth.
In witness whereof, I, the said Charles Sanderson, have hereunto set my
hand and seal, the Second day of June, in the year of our Lord One
thousand eight hundred and sixty-three.
CHARLES SANDERSON. (L.S.)
