A METHOD OF PREVENTING THE DARKNESS OF COLOUR WHICH FREQUENTLY OCCURS NEAR THE LISTS AS COMPARED WITH THE COLOUR OF THE MIDDLE OF WOOLLEN CLOTHS, IN THE PROCESS OF HEATING THEM IN WATER, OR BY STEAM ON ROLLERS
Year: 1835

page_text: HOARE, of Stonehouse, in the County of Gloucester, Clothier, send greeting.
WHEREAS I did by petition represent unto His most Excellent Majesty
King William the Fourth that I had invented "A METHOD OF PREVENTING THE
DARKNESS OF COLOUR WHICH FREQUENTLY OCCURS NEAR THE LISTS AS COMPARED WITH
THE COLOUR OF THE MIDDLE OF WOOLLEN CLOTHS, IN THE PROCESS OF HEATING THEM
IN WATER, OR BY STEAM ON ROLLERS;" and His said Majesty, being willing to
encourage all useful Inventions, did issue His Letters Patent under the Great
Seal of Great Britain, bearing date at Westminster, the First day of October,
in the sixth year of His reign, whereby His said Majesty did, for Himself, His
heirs and successors, give and grant unto me, the said Edwin Hoare, His especial
licence that I, the said Edwin Hoare, my executors, administrators, and assigns,
or such others as I, the said Edwin Hoare, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my said Invention; in which said Letters Patent
there is contained a proviso, obliging me, the said Edwin Hoare, by an instru-
ment in writing under my hand and seal, particularly to describe and ascertain
the nature of my said Invention, and in what manner the same is to be
performed, and to cause the same to be inrolled in His Majesty's High Court
of Chancery within six calendar months next and immediately after the date
of the said Letters Patent, as in and by the same, reference being thereunto
had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edwin Hoare, do hereby declare that the nature of my said Invention, and the

page_text: manner in which the same is to be performed, are described and ascertained
in manner following, that is to say:―
A in the annexed Drawing is a hollow cylinder of cast iron; B and C are two
short cylinders of wood, one at each extremity of A, and externally of exactly
the same diameter; E and F are cylindrical parts of B and C respectively, a
little smaller in diameter than the internal diameter of the cylinder A, and
contained within it, as represented by the dotted lines; D is a round bar of
wrought iron, about one inch in diameter, passing through the centre of the
said cylinder of iron and end cylinders of wood, and caps of iron G and H, to
keep them together in their places, so as to form altogether one smooth cylin-
der externally, and for this purpose D has a head at one end, and a nut and
screw at the other. The end cylinders B and C, and the iron caps G and H,
have cach two holes of about an inch in diameter through them, Figures 2
and 3, so as to form communications with the inside of the cylinder or roller
nearly parallel with the axis D, for the purpose of allowing water or steam to
pass into and out of the space within the roller surrounding D. The diameter
of the iron of the roller may be varied, so as to be made larger the greater the
quantity of cloth to be rolled upon it; for instance, a piece of cloth of forty
yards would require a roller of larger diameter than an end of cloth of twenty
yards, and the length of the roller should be adapted to the width of the cloth
to be rolled upon it; for instance, a piece of broad cloth will require a larger
roller than a cassimere. The wooden ends of the roller, however, should be
of such a length in proportion to the width of the cloth that about two nails of
the cloth within each list shall be wound upon the wood, while the rest of the
cloth within the lists shall be wound upon the iron. Several kinds of wood
may be employed, but I prefer foreign birch. The process of winding the
cloth upon the roller, and that of heating it afterwards, are commonly known
in the clothing business; and I claim as my Invention only the described
combination of wood and iron in rollers for woollen and other cloths to be
submitted, when rolled upon them, to the said process of heating.
In witness whereof, I, the said Edwin Hoare, have hereunto set my hand
and seal, this Twenty-third day of March, in the year of our Lord One
thousand eight hundred and thirty-six.
