CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1859

page_text: LETTERS PATENT to Henry Harrison, of the firm of Joseph Harrison and
Sons, of Blackburn, in the County of Lancaster, Machine Makers, for
the Invention of "CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 29th September 1859, and dated the 16th April 1859.
PROVISIONAL SPECIFICATION left by the said Henry Harrison at the
Office of the Commissioners of Patents, with his Petition, on the
16th April 1859.
I, HENRY HARRISON, of the firm of Joseph Harrison and Sons, of Black-
burn, in the County of Lancaster, Machine Makers, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN LOOMS FOR
WEAVING," to be as follows:-
In looms of the usual construction the taking-up roller is made of cast
iron, or of wood covered with emery; the former mode of construction is
objectionable owing to the cost and weight, and the latter mode is objec-
tionable because the surface requires to be turned occasionally, and then
re-covered.
My Invention consists in making the said rollers of sheet metal, thereby
combining economy, durability, and lightness. In performing my Invention
I prefer to use a sheet iron shell, attached to cast-iron discs or ends fixed to a
shaft; the shell, after being varnished, is covered with emery in the usual
manner, or it may be covered with card fillet or other rough surface.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Harrison in the Great Seal Patent Office on the
15th October 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
HARRISON, of the firm of Joseph Harrison and Sons, of Blackburn, in the
County of Lancaster, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Harrison, Her special licence that I, the said Henry Harrison,
my executors, administrators, and assigns, or such others as I, the said Henry
Harrison, 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 "CERTAIN IMPROVE-
MENTS IN LOOMS FOR WEAVING," upon the condition (amongst others) that
I, the said Henry Harrison, my executors or. administrators, by an instru-
ment 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 Henry Harrison, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):
:-
In looms of the usual construction the taking-up roller is made of cast iron,
or of wood covered with emery; the former mode of construction is objec-
tionable owing to the cost and weight, and the latter mode is objectionable
because the surface requires to be turned occasionally and then re-covered.
My Invention consists in making the said rollers of sheet metal, thereby
combining economy, durability, and lightness. In performing my Invention I
prefer to use a sheet iron shell attached to cast-iron discs or ends fixed to a
shaft, or furnished with trunnions; the shell after being varnished is covered
with emery in the usual manner, or it may be covered with card fillet or other
rough surface,

page_text: And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Drawing,
reference being had to the figures and letters marked thereon.
Fig. 1 is a longitudinal section of a taking-up roller, constructed according
to my improvements; and Fig. 2 is a transverse section of the same, taken
through the line A, B, on Fig. 1. a is the shell, which may be made of sheet
iron, copper, tin, or other suitable metal, the joint or seam of which is shewn
at b in Fig. 2. c, c, are the cast-iron end pieces or discs, fitting into the ends
of the shell, and secured by brazing or by rivets or screws; and d, d, are the
trunnions fixed into the discs c, c. In some cases the discs may be fixed on a
shaft extending through the roller. The shell of the roller after being
varnished is painted or coated with glue to secure the emery in the usual
manner, or it may be covered with card fillet or other rough surface.
Having thus described the nature and particulars of my Invention, I wish
it to be understood that I do not limit myself to the details given, as the
same may be varied or modified, but I claim the improved mode of con-
structing the taking-up rollers of looms for weaving, as described.
In witness whereof, I, the said Henry Harrison have hereto set my
hand and seal, this Fourteenth day of October, in the year of our
Lord One thousand eight hundred and fifty-nine.
HENRY HARRISON. (L.S.)
