CERTAIN IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1858

Catlow at the Office of the Commissioners of Patents, with their Petition,
on the 19th August 1858.
We, WILLIAM HUDSON, of Burnley, in the County of Lancaster, Machinist,
and CHRISTOPHER CATLOW, of Clithero, in the same County, Overlooker, do
liereby declare the nature of the said Invention of "CERTAIN IMPROVEMENTS
IN LOOMS FOR WEAVING," to be as follows:-
.The said Invention consists in the following improvements
Firstly, a mechanical arrangement or combination of parts for regulating
and controlling the delivery of warp from the warp beam in which the warp as
it passes from the warp beam to the healds is caused to pass under a moveable
rod, shaft, or roller connected to the weight levers. As the warp is taken up
in the process of weaving it has a tendency to raise the rod or roller, and the
attached weight levers along with it, and by so doing to slacken or relieve the
swag rope, chain, or break by which the necessary retarding force is applied
to the beam, the beam being thus allowed to rotate gives off portions of warp
from time to time as required.
Secondly, a mechanical arrangement or combination of parts for regulating
and controlling the delivery of warp from the warp beam, in which the said
warp is caused to pass under a moveable rod, roller, or shaft, which falls or
rises as the weaving proceeds, according as the quantity of warp delivered is in
excess or deficiency. The depression or elevation of the rod or roller so varies
the position of a strap, belt, or cord by which motion is transmitted to a worm

page_text: and worm wheel as to retard or accelerate the said motion by the greater or
less lap of the strap or tension of the cord. The rotation of the warp beam
being effected by the worn wheel, is retarded or accelerated in a corresponding
degree, and thus any excess or deficiency in the delivery is at once corrected
or compensated by the consequent alteration in the velocity of the beam.
Thirdly, an improvement upon a certain part of a former Invention for
which Her Majesty's Letters Patent were granted to us, bearing date the
Twenty-third day of July 1857; such part being described in our Specifica-
tion of the said Invention as consisting in the application of a spring to aid
the stop rod in regaining its working position after the shuttle has left the
box. Our present improvement consists in the application of a stop latch,
detent, or other contrivance to retain the stop rod in its working position, and
to prevent it from recoiling or rebounding, such stop or latch being with-
drawn or thrown out of action upon the shuttle effecting a lodgment in
either shuttle box.
Fourthly, the application of a pair of buffers (one upon each spindle) to
absorb the momentum of the pickers, and to prevent the collision thereof
with the spindle studs, such buffers being moreover connected by a small rod
or wire extending between them, so that the yielding of the one under the
impulse of the picker may replace the opposite one in its working position.
Fifthly, the construction and application of an apparatus for preventing
floats, which apparatus consists of a coarse reed or comb carried behind the
ordinary reed, and having dents with cutting edges which divide the portions
of yarn or broken ends entangled with the warp into short pieces, which may
be subsequently shaken out of the warp in the act of shedding.
