IMPROVEMENTS IN LOOMS FOR WEAVING."
Year: 1866

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
8th September 1866.
I, CHRISTOPHER CATLOW, of Burnley, in the County of Lancaster, Over-
looker, do hereby declare the nature of my said Invention for "IMPROVEMENTS
IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates, firstly, to further improvements in the "taking-up
motion" for which Letters Patent were granted to William Hudson,
Christopher Catlow, and John Dodgeon, A.D. 1863, and numbered 1994,
and consists in the use and employment of a rod or "tension roller "extending
along the periphery of the "emery roller" and attached by a link or connecting

page_text: rod at each end to the shaft of the cloth roller, the cloth passing over and
under the tension roller and on the emery roller from thence to the cloth
roller; as the cloth roller increases in diameter the links or connecting rods
which support the friction roller allow the said roller to descend on the
periphery of the emery roller, thus maintaining an uniform tension or drag
on the cloth at the varying diameter of the cloth roller.
Secondly, my improvements relate to the use and employment of weights or
springs applied to the friction or drag rollers of the "delivery motion" (delivery
of yarn from the beam), the friction of the warp actuating the said rollers
instead of actuating such rollers by means of gearing as heretofore.
Thirdly, in the application and use of a bell-crank lever and cords for the
purpose of obtaining the necessary drag on the warp beam. From one arın
of the said lever (which lever works on a stud) is a cord passed over a pulley
and attached to one end of the warp beam, to the other arm of the said
lever is attached a weighted rod or bar, a cord from the said rod or bar is
passed round the other end of the warp beam; I thus obtain an equal
weight or drag on each end of the warp beam. This arrangement is applicable
to existing looms.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Christopher Catlow in the Great Seal Patent Office on
the 7th March 1867.
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 Eighth day of September, in the year of our Lord One
thousand eight hundred and sixty-six, in the
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 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)

page_text: •
that I, the said Christopher Catlow, my executors or administrators, 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 mouths 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.
This Invention relates, firstly, to further improvements in the "taking-up
motion" for which Letters Patent were granted to William Hudson,
Christopher Catlow, and John Dodgeon, A.D. 1863, and numbered 1994,
and consists in the use and employment of a rod or "tension roller" extending
along the periphery of the " emery roller," and attached by a link or connecting
rod at each end to the shaft of the "cloth roller;" the cloth passing over and
under the tension roller, and on the emery roller, from thence to the cloth
roller. As the cloth roller increases in diameter the links or connecting rods.
which support the friction roller allow the said roller to descend on the
periphery of the emery roller, thus maintaining an uniform tension or drag on
the cloth at the varying diameter of the cloth roller.
Secondly, my improvements relate to the use and employment of weights
or springs applied to the friction or drag rollers of the "delivery motion"
(delivery of yarn from the beam),, the friction of the warp actuating the said
rollers instead of actuating such rollers by means of gearing as heretofore.
Thirdly, in the application and use of a bell-crank lever and cords for the
purpose of obtaining the necessary drag on the warp beam. From one arm of the
said lever (which lever works on a stud) is a cord passed over a pulley and
attached to one end of the warp beam, to the other arm of the said lever is
attached a weighted rod or bar, a cord from the said rod or bar is passed
round the other end of the warp beam; I thus obtain an equal weight or drag
on each end of the warp beam. This arrangement is applicable to existing
looms.
Such being the nature and object of this my said Invention, I will now
proceed to describe the same more fully, and in order that the same may be
clearly understood I have hereunto annexed a Sheet of Drawings illustrative
thereof, and have marked the same with letters of reference, the same letter
refering to the same part in the various Views or Figures.

the rod or "tension roller" extending along the periphery of the emery roller B;
the tension roller A is connected at each end of the cloth roller C by means
of the connecting rods D. E shews the ordinary breast beam of the loom
over which the cloth passes to the cloth roller C, as shewn by dotted line;
Fig. 3 shews the same with weight F and lever G applied; Fig. 4 shews
connecting rod D elongated, and the end thereof is chased or screwed and
passed through an eye in the end of the spring H, the spring serving to impart
elasticity to the action of the roller A; this arrangement I employ in weaving
long lengths of cloth. Fig. 5 shews the application of weights to the friction
or draw rollers of the "delivery motion," in which K, K, are the friction or

fixed to the side frame M', to which stud is attached one end of the rope N,
which rope is passed over the rollers K, K, and to the other end of such rope
the weight N is attached; the warp from the warp beam P being passed
over one roller K and under tho other roller K (as shewn by dotted line)
to the healds; the friction of the warp on the rollers K, K, serving to actuate
them instead of employing gearing for that purpose as hitherto; at Fig. 6
I shew application of bell-crank lever R, weight R', and cords R' and R³ for
the purpose of obtaining the necessary drag on the warp beam; the lever R
works on the stud S, the cord or chain Rª being attached to cross rail T and
passed around the end of the warp beam and the other end secured to the
lever R; the rope R³ is also attached to the cross rail and passed around the
other end of the warp beam, and from thence over the pulley V and connected
by the rod W with the lower part W' of the lover R. I thus obtain an equal
drag on each end of the warp beam without the cumbersome weights and
lever as heretofore applied to looms for weaving.
Having thus fully described the nature and particulars of this my said
Invention, and the manner in which the same is to be or may be performed
or carried into practical effect, I would havo it distinctly understood that
what I claim as my Invention is,―
Firstly, the apparatus employed for " 'taking-up" the cloth as herein
described and illustrated in the Drawings.
Secondly, the arrangement of the drag rollers, and the method of actuating
such rollers by means of the warp, as herein described and illustrated in the
Drawings.
Thirdly, the bell-crank lever for the purpose of obtaining the necessary

page_text: drag on the warp beam, constructed and arranged as herein described and
illustrated in the accompanying Drawings.
In witness whereof, I, the said Christopher Catlow, have bereunto set
my hand and seal, this Fourth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven.
