page_text: LETTERS PATENT to John Butterworth and William Dickinson,
Machinists, and Christopher Catlow, Overlooker, all of Burnley,
in the County of Lancaster, for the Invention of "IMPROVEMENTS IN
LOOMS FOR WEAVING."
Sealed the 5th May 1876, and dated the 6th November 1875.
PROVISIONAL SPECIFICATION left by the said John Butterworth,
William Dickinson, and Christopher Catlow at the Office of the
Commissioners of Patents, with their Petition, on the 6th
November 1875.
We, JOHN BUTTERWORTH and WILLIAM DICKINSON, Machinists, and
CHRISTOPHER CATLOW, Overlooker, all of Burnley, in the County of
Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates to the use of improved means and apparatus
for operating the cloth beam or roller of looms on which the cloth is
woven, and to improvements in the crank journals of loom crank shafts.

page_text: whereby the latter are rendered more durable: We affix on the end
of the shaft of the "taking up" roller and also on the end of the shaft
of the cloth beam a grooved pulley, round which pulley is passed as
many times as necessary an endless driving band or cord. The cord in
passing from the grooved pulley on the shaft of the taking up roller
(which is the driver) is crossed before passing round the pulley on the
shaft of the cloth beam so as to turn the latter in the proper direction,
the slack of the cord forms a pendant loop below the axis of the cloth
beam within which loop is a small pulley, having attached thereto a
weight or spring for keeping the endless driving cord at a proper tension
during the varying diameters of the cloth beam; an adjustable
tension pulley may also be applied to such cord so as to give to the cord
more or less grip on one or other of the pulleys.
In another arrangement having a like object, an endless strap is to
be passed partly round the take-up roller, the strap thence passes
downwards; in the pendant loop is a pulley,, and a spring is connected
therewith for purpose as above described. An adjustable tension pulley
is applied to the strap, so as to cause a portion thereof to partly embrace
the end of the cloth beam, whereby. the motion of the taking-up roller
is transmitted to the cloth beam.
The arrangements above described are intended for use in connection
with a smooth taking-up roller.
On looms having a "roughed" or "emery" taking-up roller, the
means we employ for taking up and smoothing the cloth are as
follows:-
The cloth beam is fixed a distance apart from the roughed or emery
roller and has no direct connection therewith. The cloth as woven
passes over the breast beam under the cloth beam, thence in an upward
direction to the back of and over the take-up emery or roughed roller
down to and around the cloth beam, forming an endless webb through
which the motion imparted to the taking-up roller is transmitted to the
cloth beam: From each end of the shaft or axis of the taking-up roller
is a rod or arm connected to the lower ends of which is a cross bar;
over which the cloth passes on its way to the beam; whereby the cloth
is rendered smooth and even.
When forging the sweep journals of the crank shafts we weld or
shrink thereon a band or casing of steel, whereby the journals arê

driving than when formed of the softer metal-wrought iron-of which
the crank shaft is composed.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of November, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Butterworth, William
Dickinson; and Christopher Catlow, Her special licence that we, the
said John Butterworth, William Dickinson, and Christopher Catlow,
our executors, administrators, and assigns, or such others as we, the
said John Butterworth, William Dickinson, and Christopher Catlow,
our 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,
usc, 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 we, the said John Butterworth, William Dickinson, and
Christopher Catlow, our executors or administrators, by an instrument
in writing under our, or their, or one of our or 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
months next and immediately after the date of the said Letters
•

page_text: NOW KNOW YE, that we, the said John Butterworth, William
Dickinson, and Christopher Catlow, do hereby declare the nature of
our 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 :-
This Invention relates to the use of improved means and apparatus
for operating the cloth beam or roller of looms on which the cloth is
woven, and to improvements in the crank journals of loom crank shafts,
whereby the latter are rendered more durable. We affix on the end of
the shaft of the "taking up" roller, and also on the end of the shaft
of the cloth beam a grooved pulley, round which pulleys is passed as
many times as necessary an endless driving band or cord. The cord in
passing from the grooved pulley on the shaft of the taking-up roller
(which is the driver) is crossed before passing round the pulley on the
shaft of the cloth beam, so as to turn the latter in the proper direction;
the slack of the cord forms a pendant loop below the axis of the cloth
beam, within which loop is a small pulley having attached thereto a
weight or spring for keeping the endless driving cord at a proper tension
.during the varying diameters of the cloth beam; an adjustable tension
pulley may also be applied to such cord, so as to give to the cord more
or less grip on one or other of the pulleys.

•
In another arrangement, having a like object, an endless strap is to
be passed partly round the take-up roller, the strap then passes
downwards; in the pendant loop is a pulley, and a spring is connected
therewith for purpose as above described. An adjustable tension pulley
is applied to the strap, so as to cause a portion thereof to partly embrace
the end of the cloth beam, whereby the motion of the taking-up roller
is transmitted to the cloth beam..
The arrangements above described are intended for use in connection
with a smooth taking-up roller.
On looms having a "roughed" or "emery" taking up roller, the
means we employ for taking up and smoothing the cloth are as
follows:-
°
The cloth beam is placed a distance apart from the roughed or emery
roller and has no direct connection therewith." The cloth as woven
'passes over the breast beam, under the cloth beam, thence in an upward
direction to the back of and over the take-up emery or roughed roller,

page_text: (
down to and around the cloth beam, forming an endless web through
which the motion imparted to the taking up roller is transmitted to the
cloth beam. From each end of the shaft or axis of the taking-up roller
is a rod or arm, connected to the lower ends of which is a cross bar over
which the cloth passes on its way to the beam, whereby the cloth is
rendered smooth and even.
When forging the sweep journals of the crank shafts we weld or
shrink thereon a band or casing of steel, whereby the journals are
rendered more durable, and work smoother, and require less power for
driving than when formed of the softer metal, wrought iron, of which
the crank shaft is composed.
Such being the nature and object of this Invention, we will now
proceed to describe the same more fully, and in order that the same
'may be fully understood we have hereunto annexed a Sheet of Drawings,
and have marked the same with figures and letters of reference.
DESCRIPTION OF THE DRAWINGS.
.
Fig. 1. On the end of the shaft of the "taking-up" roller A, and
also on the end of the shaft of the cloth beam B, a grooved pulley C
and D, round which pulleys is passed as many times as necessary an
´endless driving band or cord E. The cord E in passing from the grooved
pulley on the shaft of the taking-up roller, A. (which is the driver) is
crossed before passing round the pulley C on the shaft of the cloth
beam B, so as to turn the latter in the proper direction, the slack of the
cord E forms a pendant loop below the axis of the cloth beam, within
which loop is a small pulley F, having attached thereto a weight G or
spring for keeping the endless driving cord at a proper tension during
the varying diameters of the cloth beam, an adjustable tension pulley
may also be applied to such cord, so as to give to the cord more or less
grip on one or other of the pulleys; the hand H wheel or axis of the
cloth beam is for "taking up' " after "letting back" when a float
occurs, or when from other cause it has been necessary to let back a
portion of the cloth woven.
•
Fig. 2 shews another arrangement having a like object, an endless
strap A is to be passed partly round the take-up roller B, the strap
thence passes downwards; in the pendant loop is a pulley C, and a
spring D is connected therewith for purpose as above described. An

page_text: adjustable tension pulley E is applied to the strap so as to cause a
portion thereof to partly embrace the end of the cloth beam, whereby
the motion of the taking-up roller is transmitted to the cloth beam.
The arrangements above described are intended for use in connection
with a smooth taking-up roller.
Fig. 3 shews a modified arrangement whereon the cord or strap A
is secured to the shaft or axis of the cloth beam B, and thence passes
to and as many times around the axis (or a pulley thereon) of the
roller C as necessary, thence over the stud or pulley D, which latter
serves to prevent the cord or strap rubbing upon the cloth), and a
weight E is attached to its termination.
At Fig. 4 is shewn the cloth beam, A is placed. a distance apart from
the roughed or emery roller B, and has no direct connection therewith.
The cloth as woven passes over the breast beam .C, under the cloth
beam A, thence in an upward direction to the back of and over the
take-up emery or roughed roller B down to and around the cloth beam,
forming an endless web through which the motion imparted to the
taking-up roller is transmitted to the cloth beam. From each end of
the shaft or axis of the taking-up roller is a rod or arm E, connected
to the lower ends of which is a cross bar F, over which the cloth passes
on its way to the beam, whereby the cloth is rendered smooth and
even.
Figs. 5, 6, 7. When forging the sweep journals of the crank shafts we
weld or shrink thereon a band or casing of steel A, which is afterwards
turned down to the proper form for receipt of the brasses. When
making new crank shafts the band A is more readily applied before the
shaft is bent or cranked.
Having thus fully described and illustrated the nature and particulars
of this our said Invention, we would have it understood that we lay no
claim separately to either the cord or to the pulleys herein referred to,
but what we do is,―
Firstly. The combination of rope, strap, or chain, and pullies, when
arranged and applied in the manner and for the purpose herein fully
described and illustrated.

In witness whereof, I, the said Christopher Catlow, for and on
behalf of myself and the said John Butterworth and William
Dickinson, have hereunto set my hand and seal, this Second
day of May, in the year of our Lord one thousand eight hundred
and seventy-six.
