Year: 1858

page_text: LETTERS PATENT to Hiram Hutchinson, of the City of Paris, France, for
the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF INDIA-RUBBER
Goods."
Sealed the 8th April 1859, and dated the 29th December 1858.
PROVISIONAL SPECIFICATION left by the said Hiram Hutchinson at
the Office of the Commissioners of Patents, with his Petition, on the
29th December 1858.
I, HIRAM HUTCHINSON, of the City of Paris, France, do hereby declare the
nature of the Invention for "IMPROVEMENTS IN THE MANUFACTURE OF INDIA-
RUBBER GOODS," to be as follows:-
This Invention has for its object improvements in the manufacture of india--
rubber goods. In producing articles consisting either entirely or in part of
cloth, leather, or other material coated or combined with india-rubber, it is
usual to cut pieces of the shape necessary for the formation of the required.
article from a sheet of cloth, leather, or other material coated over its whole
surface with india-rubber, from which considerable waste of india-rubber-
results.
Now, according to my Invention, in coating sheets of cloth, leather, or
other material with india-rubber when such sheets are to be cut up into
shaped pieces, I only coat or combine such sheets with india-rubber at certain
places in pieces of the size and form required, and this I do by passing. the.

page_text: sheet of cloth, leather, or other material, together with a sheet of india-rubber
prepared in the usual manner, between rollers, on one of which a raised
pattern is formed or fixed, and this raised pattern, by pressing the sheet of
cloth, leather, or other material and the india-rubber together, causes the
india-rubber to coat or combine with the sheet of cloth, leather, or other
material at the parts touched by the pattern, whilst at the parts which receive
no pressure no adhesion is produced between the cloth, leather, or other
material and the india-rubber. In place of a pattern roller, two plain rollers
may be employed, and a pattern cut out or formed in suitable material may be
passed together with the sheet of cloth, leather, or other material and the
india-rubber between the rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Hiram Hutchinson in the Great Seal Patent Office on the
28th June 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HIRAM
HUTCHINSON, of the City of Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of December, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Hiram Hutchinson, Her special licence that I, the said Hiram
Hutchinson, my executors, administrators, and assigns, or such others as I, the
said Hiram Hutchinson, 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 "IMPROVE-
THE MANUFACTURE OF INDIA-RUBBER GOODS," upon the condition
(amongst others) that I, the said Hiram Hutchinson, my executors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly 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 Hiram Hutchinson, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: .
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of india-
rubber goods. In producing articles consisting either entirely or in part of
cloth, leather, or other material coated or combined with india-rubber, it is
usual to cut pieces of the shape necessary for the formation of the required
article from a sheet of cloth, leather, or other material coated over its whole
surface with india-rubber, from which considerable waste of india-rubber
results.
Now, according to my Invention, in coating sheets of cloth, leather, or
other material with india-rubber when such sheets are to be cut up into
shaped pieces, I only coat or combine such sheets with india-rubber at certain
places in pieces of the size and form required, and this I do by passing the
sheet of cloth, leather, or other material together with a sheet of india-rubber
prepared in the usual manner between rollers, on one of which a raised pattern
is formed or fixed, and this raised pattern by pressing the sheet of cloth,
leather, or other material and the india-rubber together causes the india-
rubber to coat or combine with the sheet of cloth, leather, or other material at
the parts touched by the pattern, whilst at the parts which receive no pressure
no adhesion is produced between the cloth, leather, or other material and the
india-rubber.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawing hereunto
annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a front view, and Figure 2 is a longitudinal section, of a machine
such as I prefer to employ for coating or covering a continuous sheet of cloth
or other material with india-rubber at places or patches of the size and form
required. for the manufacture of the articles for which the coated or covered
fabric or material is required. The machine consists of three plain rollers
a, b, c, placed one over the other, and geared together and driven as the
Drawing shows; the distances between these rollers can be adjusted by means
of screws in the usual manner. The india-rubber in a plastic state as it comes
from the masticator is fed in between the lower pair b, c, of these rollers, and
is by them rolled out into a sheet which passes up round the centre roller and
between it and the top roller a; d is the pattern roller, a side view of which on
a larger scale is shown at Figure 3, and a transverse section at Figure 4; the
pattern may either be cast on the surface, or may be attached by screws, as is

page_text: shown at Figure 5; the roller d is mounted on the frame of the machine in
such a manner that its distance from the roller a may be adjusted as may be
required according to the thickness of the covered fabric or material to be
produced; e and fare beams, on which the fabric or material to be coated or
covered is wound; it passes continuously while the machine is at work from
the lower beam e to the upper beam f, which is driven by cone pulleys, or in
other convenient manner, so that its surface speed may be at all times equal to
that of the rollers a, b, c. The fabric or material in passing from the beam e
to the beam fpasses round the pattern roller d, and is brought in contact
with the sheet of india-rubber, against which at parts it is strongly pressed by
the raised or pattern surface of the roller, and at such parts a complete
adhesion or union between the india-rubber and the fabric or material is
obtained, whilst the remaining portions of the india-rubber are left on the roll.
Figure 6 is a machine such as I prefer to employ for covering a continuous
sheet of cloth or other material on both sides at certain parts only in the
manner already described. It consists of two pair of plain rollers g, h, and
g¹, h¹; between each pair india-rubber in a plastic state is fed, which. becomes
rolled out into sheets, and passes round the rollers h and h', and between them
and the pattern rollers i and , together with the fabric or material which
passes continuously from the beamj to the beam k, the beam k being driven
as in the other machine. In covering leather with india-rubber, as it cannot
readily be made up into a continuous sheet to roll on the beams e, f, of the
machine, Figures 1 and 2, or the beams j, k, of the machine, Figure 6, the
skins are fed into the machine by a workman, who enters the skins in
succession between the rollers. In place of a pattern roller, two plain rollers
may be employed, and a pattern cut out or formed in suituable material may
be passed together with the sheet of cloth, leather, or other material and
india-rubber between the rollers..
In witness whereof, I, the said Hiram Hutchinson, have hereunto set
my hand and seal, this Fifteenth day of June, in the year of our
Lord One thousand eight hundred and fifty-nine.
