Year: 1881

page_text: LETTERS PATENT to George Lamb Scott, of Manchester, in the County of
Lancaster, Engineer, for an Invention of "IMPROVEMENTS IN AND IN THE
MANUFACTURE OF .. MATERIALS AND APPLIANCES COMPOSED PARTLY OF
VULCANISED CAOUTCHOUC."
PROVISIONAL SPECIFICATION left by the said George Lamb Scott at
the Office of the Commissioners of Patents on the 4th May 1881.
GEORGE LAMB SCOTT, of Manchester, in the County of Lancaster, Engineer,
"IMPROVEMENTS IN AND IN THE MANUFACTURE OF MATERIALS AND APPLIANCES
COMPOSED PARTLY OF VULCANISED CAOUTCHOUC."
My said Invention relates in the first place to the combination of caoutchouc
with a fabric, and has for its principal object to produce materials suitable for use
in the packing of steam, hydraulic, and other joints, and in the packing of goods,
and for many other purposes. Previously to my Invention woven material has
been coated with caoutchouc or has been embedded therein. According to my
Invention I employ paper in lieu of the woven material and thereby obtain
materials applicable for many uses for which the ordinary material is not suitable.
I coat the paper either on one side or on both sides with the caoutchouc, the
coating being for some uses exceedingly thin and for other uses being thicker, the
thickness varying according to the use for which the material is intended. For
some uses the paper is applied to a sheet or between two sheets of caoutchouc, or
two or more layers of paper are interposed between several sheets of caoutchouc.
The caoutchouc used is prepared for vulcanization and the treated paper or combined
materials is or are subjected to the vulcanizing process. Materials so produced may
be cut into joint rings or washers and be used as a water proof or damp proof
material in the packing of goods or in the lining of walls and be otherwise used
for purposes too numerous to mention herein. I also produce driving belts from
the material by folding the coated paper before the vulcanizing process until a
D

page_text: suitable number of thicknesses is obtained, or by superimposing a number of layers
of the coated material, or by both methods. The folds or layers may be stitched
or secured together if considered to be necessary or advisable. The material is
subsequently vulcanized. Iron, steel, or other material may be combined with the
paper or caoutchouc. In the second place I glue or cement sheet caoutchouc which
has been vulcanized upon a backing of paper to both sides of blocks of wood, papier
maché, or other similar material, in order to obtain packings for various purposes,
as, for example, packings so produced may be applied to railway carriages in lieu of
solid blocks of vulcanized caoutchouc. I may interpose two or more layers of the
wood or papier maché between sheets of the caoutchouc. In a modification of this
part of my Invention I employ sheet caoutchouc prepared in any ordinary or
suitable manner.

GEORGE LAMB SCOTT, of Manchester, in the County of Lancaster, Engineer,
"IMPROVEMENTS IN AND IN THE MANUFACTURE OF MATERIALS AND APPLIANCES

My said Invention relates in the first place to the combination of caoutchouc
with a fabric, and has for its principal object to produce materials for use in the
packing of steam, hydraulic, and other joints, and in the packing of goods, and for
many other purposes. Previously to my Invention woven material has been coated
with caoutchouc, or has been embedded therein. According to my Invention I
employ paper in lieu of the woven material and thereby obtain materials applicable
for many uses for which the ordinary material is not suitable. I coat the paper
either on oue side or on both sides with the caoutchouc, the coating being for some
uses exceedingly thin and for other uses being thicker, the thickness varying
according to the use for which the material is intended. For some uses the paper
is applied to a sheet or between two sheets of caoutchouc, or two or more layers of
paper are interposed between several sheets of caoutchouc. The caoutchouc used
is prepared for vulcanization and the treated paper or combined materials is or are
subjected to the vulcanizing process. Materials so produced may be cut into joint
rings or washers and be used as a water proof or damp proof material in the
packing of goods or in the lining of walls, and be otherwise used for purposes too
numerous to mention herein. For some uses, as, for example, when intended to be
used in the covering or lining of walls or floors, the material may be ornamented
by printing or embossing, or by other suitable means or processes. I also produce
driving belts from the material by folding the coated paper before the vulcanizing
process until a suitable number of thicknesses is obtained, or by superimposing a
number of layers of the coated material, or by both methods. The folds or layers
may be stitched, riveted, or secured together in any suitable manner if considered
to be necessary or advisable. The material so produced is submitted to the
vulcanizing process. Iron, steel, or other material may be combined with the
prepared paper or with the caoutchouc, or be interposed between the layers of
paper. In the second place I glue or cement sheet caoutchouc which has been
vulcanized upon a backing of paper to both sides of blocks of wood, papier maché,
or other similar material, in order to obtain packings for various purposes, as, for
example, packings so produced may be applied to railway carriages in lieu of solid
blocks of vulcanized caoutchouc. I may interpose two or more layers of the wood
or papier maché between sheets of the caoutchouc. In a modification of this part
of my Invention I employ sheet caoutchouc prepared in any ordinary or suitable
manner in lieu of the paper backed caoutchouc, the said sheet caoutchouc being
cemented to the blocks of wood, papier maché,. or other material, either before or
after being vulcanized as preferred or found to be most suitable.
Having now fully set forth the nature of my said Invention, and the manner in
which
carry or may carry the same into practical effect, I would have it to
be understood in conclusion that what I consider to be novel and desire to
claim is,
Firstly. The manufacture of materials composed of paper coated on one side or
on both sides with caoutchouc and subsequently vulcanized, substantially as and for
the nunnoong cat farth and indinated

page_text: And, Secondly. The packings for railway carriages and other purposes, substan-
tially as set forth.
In witness whereof, I, the said George Lamb Scott, have hereunto set my
hand and seal, this Second day of November, in the year of our Lord, One
thousand eight hundred and eighty-one.
