IMPROVEMENTS IN LOOMS FOR WEAVING."
Year: 1872

page_text: LETTERS PATENT to Christopher Catlow, of Burnley, in the County
of Lancaster, Overlooker, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Christopher Catlow at
the Office of the Commissioners of Patents, with his Petition, on
the 18th April 1872.
I, CHRISTOPHER CATLOW, of Burnley, in the County of Lancaster,
Overlooker, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
•
This Invention relates to the crank arms in looms for weaving where
straps, "gib," and cotter are used for adjusting the bearings of the said
arms to the crank shaft and to the pin of the sword arm. Heretofore
in these arms by the action of the loom the "gibs" soon wear away, or.

page_text: they cut into the straps and require frequent setting up or repairs.
Now to remedy this I extend the under strap sufficiently to enable me
to pass a screw bolt through both the straps and also through the arm,
so that when the straps are set or adjusted by the cotter this bolt can
be screwed tight up, which will prevent any action or movement of the
said straps, and thus prevent or diminish the wear of these parts.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Christopher Catlow in the Great Seal Patent
Office on the 18th October, 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTOPHER ]
CATLOW, of Burnley, in the County of Lancaster, Overlooker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of April, in the year of
our Lord One thousand eight hundred and-seventy-two, in the thirty- 1
fifth year of Her reign, did, for Herself, Her heirs and successors give
and grant unto me, the said Christopher Catlow, Her special licence
that I, the said Christopher Catlow, my executors, administrators, and
assigns, or such others as I, the said Christopher Catlow, my executors,
administrators, and assigns, should at any time agree with, and no 2
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 "IMPROVEMENTS IN
LOOMS FOR WEAVING," upon the condition (amongst others) that I, the 2
said Christopher Catlow, 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 Inven-
tion, 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 8
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Christopher Catlow, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):
-
This Invention relates to the crank arms in looms for weaving, where
straps, "gib," and cotter are used for adjusting the bearings of the said
3 arm to the crank shaft and to the pin of the sword arm. Heretofore
in these arms by the action of the loom, the gibs soon wear away, or
they cut into the straps and require frequent setting up or repairs. Now
to remedy this I extend the under strap sufficiently to enable me to pass
a screw bolt through both the straps and also through the arm, so that
when the straps are set or adjusted by the cotter this bolt can be screwed
tight up, which will prevent any action or movement of the said straps,
and thus prevent or diminish the wear of these parts.
Such being the nature and object of this my said Invention, I will
now proceed to describe the same in detail, and in order that the same
may be fully understood, I have hereunto annexed a Sheet of Drawings,
and have marked the same with figures and letters of reference, the
same letter referring to the same part in the various views or figures.

In witness whereof, I, the said Christopher Catlow, have hereunto
set my hand and seal, this Sixteenth day of October in the year
of our Lord One thousand eight hundred and seventy-two.
