IMPROVEMENTS IN LOOKS FOR WEAVING
Year: 1871

page_text: LETTERS PATENT to Christopher Catlow, of Burnley, in the County
of Lancaster, Overlooker, for the Invention of "IMPROVEMENTS IN
LOOKS FOR WEAVING."
Sealed the 26th March 1872, and dated the 30th September 1871.
PROVISIONAL SPECIFICATION left by the said Christopher Catlow at
the Office of the Commissioners of Patents, with his Petition, on
the 80th September 1871.
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,—
Firstly. To the use or employment of a pair of vibrating rollers suspended
immediately over or above the warp beam in a swing frame, the warp
passing from the beam under and over the bottom one of the two rollers
and under and over the top rollers, thence to the healds or heddles; the
weight rope or chain is passed over a pulley on the top roller, the position

page_text: or angle at which the fixed end of the weight rope or chain is relative to
the pulley, determines the freedom or otherwise of delivery from the
warp beam; the said swing frame is operated by means of a lever and
eccentric.
Secondly. The Invention relates to a self-acting adjustment of the
weight on or weighting of the warp beam. This I effect by means of a
concave intermediate bearer," or tension bar extending from an arm of
a lever on each side of the loom to a point under and near the ordinary
back bearer; the warp in its passage from the beam bears in the
"intermediate bearer," and as the beam decreases in diameter the levers ]
to which the said bearer are attached raise the weight, and thus adjust
the tension on the warp to the change of diameter of the warp beam.
Thirdly. To the construction of apparatus for "turning off" or
delivering the warp from the beam by means of a vibrating warp bearer
or shedding motion, comprising a lever and eccentric, actuating the 1
back bearer; also an arm attached to the boss of the said lever
supporting an adjustable bearer.
Fourthly. To apparatus for and means of adjusting the weight on the
weight lever. This I effect by means of a rod connected to the back
bearer and to the loose end of a lever, the other end of this lever is 2
connected or linked to the loose end of the ordinary weight lever, so that
the first lever will by the pressure of the warp on the back bearer be
raised, and the weight on the weight lever move nearer the fulcrum
thereof, and so the weighting of the beam is regulated.
Fifthly. In the construction and employment of a cranked weighted 2
lever, its fulcrum being the axis of the cloth roller, the weighted end of
the lever being operated by means of an eccentric, the other end of the
said lever carries two catches which take into the notches of a catch
wheel (or a friction wheel may be employed) placed on the end of the
cloth roller, so as to prevent the said roller and cloth thereon slipping. 3
I also employ hooks fixed to the plain roller for the purpose of hooking
on the "lap" or commencement of the warp. I lift the driving catch
instead of the holding catch in combination with the apparatus described
under this heading.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHRISTOPHER
CATLOW, of Burnley, in the County of Lancaster, Overlooker, send
grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of September, in
the year of our Lord One thousand eight hundred and seventy-one, in
the thirty-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, adminis-
trators, and assigns, or such others as I, the said Christopher Catlow,
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 "IMPROVEMENTS IN LOOMS FOR WEAVING," upon the condition (amongst
others) that I, the said Christopher Catlow, my executors or adminis-
trators, 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 Christopher Catlow, 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 and accompanying Sheet of Drawings,
that is to say:-

page_text: two rollers, and under and over the top rollers, thence to the healds or
heddles; the weight rope or chain is passed over a pulley on the top
roller, the position or angle at which the fixed end of the weight rope or
chain is relative to the pulley determines the freedom or otherwise of
delivery from the warp beam; the said swing frame is operated by means 5
of a lover and eccentric.
Secondly. The Invention relates to a self-acting adjustment of the
weight on or weighting of the warp beam. This I effect by means of a
concave "intermediate bearer" or tension bar extending from an arm of
a lever on each side of the loom to a point under and near the ordinary 1
back bearer; the warp in its passage from the beam bears on the inter-
mediate bearer, and as the beam decreases in diameter the levers to
which the said bearers are attached raise the weight, and thus adjust the
tension on the warp to the change of diameter of the warp beam.
Thirdly. To the construction of apparatus for "turning off" or 1
delivering the warp from the beam by means of a vibrating warp
bearer or shedding motion, comprising a lever and eccentric, actuating
the back bearer; also an arm attached to the boss of the said lever
supporting an adjustable bearer.
Fourthly. To apparatus for and means of adjusting the weight on the 2
weight lever. This I effect by means of a rod connected to the back bearer
and to the loose end of a lever, the other end of this lever is connected
or linked to the loose end of the ordinary weight lever, so that the first
lever will by pressure of the warp on the back bearer be raised, and the
weight on the weight lever move nearer the fulcrum thereof, and so the 2
weighting of the beam is regulated.
Fifthly. In the construction and employment of a cranked weighted
lever, its fulcrum being the axis of the cloth roller, the weighted end of
the lever being operated by means of an eccentric, the other end of the
said lever carries two catches which take into the notches of a catch 3
wheel (or a friction wheel may be employed) placed on the end of the
cloth roller, so as to prevent the said roller and cloth thereon slipping.
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 clearly understood, I have hereunto annexed a Sheet of Drawings ;
illustrative thereof, in which Figs. 1 and 2 are sido and back elevation

page_text: T is a cranked weighted lever, its fulcrum being the axis of the cloth
roller T, the weighted lever being operated by means of the eccentric V,
the other end of the said lever carries the two catches W, W¹, which
engage with the notches of the catch wheel X (or a friction wheel may
be employed) placed on the end of the cloth roller T' so as to prevent
the said roller and cloth slipping.
Having thus fully described the nature and particulars of this my said
Invention, together with the manner in which the same is to be or may
be performed or carried into practical effect, I would have it understood
that I claim,―
Firstly. The vibrating rollers, together with the swing frame for
carrying the same, as and for the purpose herein fully described.
Secondly. The links or rods J, J, connected or attached to the end of
the weight levers as and for the purpose hercin fully described and
shewn in the Drawings.
Thirdly. The adjustable bar or roller K³, as and for the purpose herein
fully shewn and illustrated.
Fourthly. The means of and apparatus for adjusting the weight on
the weight lever as shewn at Figs. 7 and 8 of the Drawings, and herein
fully described.
Lastly. The arrangement of the adjustable weighted lever and catches
operated by the eccentric as described and shewn in the Drawings.
In witness whereof, I, the said Christopher Catlow, have hereunto
set my hand and seal, this Twenty-seventh day of March, One
thousand eight hundred and seventy-two.
