LETTERS PATENT to Matthew Pedley and David Pedley, Stuff Manu-
facturers, both of Bradford, in the County of York, for the
T
OVEMENTS IN
LOOMS FOR WEAVING.
PROVISIONAL SPECIFICATION left by the said Matthew Pedley and
David Pedley at the Office of the Commissioners of Patents, with
their Petition, on the 19th September 1871.
We, MATTHEW PEDLEY and DAVID PEDLEY, Stuff Manufacturers,
5 both of Bradford, in the County of York, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN-LOOMS FOR WEAVING,"
to be as follows:-

page_text: in applying a self-acting motion to the beams for the delivery of any
length of yards of warps in one cut into any length of yards in the
other cut, to make each cut mark come together, at the same time
producing a more even fabric and preventing such warps from twisting
or stretching, as in the case with looms as ordinarily arranged. For
carrying out this part of our Invention we employ a set of three spur
wheels, two of which are fixed on the spindles of the beams and are
operated by means of an intermediate wheel fastened to a loose lever
bracket bolted to the loom frame. This lever bracket has a slot hole cut
in it to allow the moving of the intermediate wheel when the small
wheel fixed on the small beam has to be changed when the different
lengths of cuts are required to be worked together. The large beam
receives its motion in the usual manner, and on the spindle a
spur wheel equal in diameter to the intermediate wheel is fastened.
This wheel in revolving communicates its motion to the intermediate
wheel and this wheel working in the small wheel fastened on the spindle
of the small beam gives motion to the beam. The only wheel requiring
altering in size to allow of the changes in the warps is the small wheel
fixed on the small beam, and the size of this wheel is obtained by
multiplying the diameter of the drivers by that of the driven and
dividing the greater by the smaller.
Our Invention relates, secondly, to the application of a guide rod on
the top of the back still beam, which is fixed by means of two small
cast-iron brackets fastened by set screws on the still beam. This guide
rod is for the purpose of keeping the warps in constant evenness with
the heel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Pedley and David Pedley in the Great
Seal Patent Office on the 16th March 1872.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
PEDLEY and DAVID PEDLEY, Stuff Manufacturers, both of Bradford, in
the County of York, send greeting.

page_text: 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 us, the said Matthew Pedley and David Pedley,
Her special licence that we, the said Matthew Pedley and David
Pedley, our executors, administrators, and assigns, or such others as
we, the said Matthew Pedley and David Pedley, our executors, adminis-
trators, 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 we, the said
Matthew Pedley and David Pedley, our executors or administrators, by
an instrument in writing under our, 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 Scal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Matthew Pedley and David
Pedley, 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, reference being
had to the Drawing hereto annexed and to the figures and letters
marked thereon, that is to say:-
Our Invention relates to means or apparatus for the delivery of warps
in any number of separate beams, and in order that the improvements
may be fully understood, we will by the aid of the accompanying
Drawing proceed to describe means pursued by us in carrying the same
> into effect.
Figure 1 side elevation, Figure 2 end elevation, and Figure 3
plan of self-acting motion attached to the frame of a loom. In each of
these Figures the same letters indicate corresponding parts.

page_text: A, frame of the loom carrying the large beam spindle B, and having a
bracket C bolted to it to receive the spindle D of the small beam K, and
also receiving the loose lever bracket E, which is fastened to it by means
of a bolt and nut. This lever bracket E has a slot hole F cast in it
to allow of the bracket being shifted when the intermediate wheel I' has
to be moved to cause its coming into gear with any change, made in the
small wheel J. This same wheel J is removed and replaced by another
wheel smaller or larger in diameter according to the changes made in
the warps. G large, driving wheel fixed on the large beam spindle B
and receiving its motion in the usual way. This wheel works the large
beam H and imparts its motion to the intermediate wheel I, which
in revolving communicates its movement to the small wheel J turning
the small beam K. The large wheel G and the intermediate wheel
I are made equal in diameter, and the only wheel requiring altering in
size and removing to allow for the changes in the warps is the. small 1
wheel J fixed on the spindle D of the small beam K. The diameter
of this wheel is obtained by. multiplying the driving wheel by the
wheel driven, and dividing the greater by the smaller, together with
the circumferences of the beams. E bracket bolted to the loom frame,
having a slot hole F cast or cut in it to allow of its being moved 2
with the intermediate wheel I when a change is made with, the small
wheel J. The wheel I is put on the pin L, which is fixed to the bracket
E and kept in its place by means of the collar M. C brackets bolted to
the loom frames A carrying the spindle D of the small beam K., N¸ still
