IM- PROVED ARRANGEMENTS OF WARPS IN SIZING OR DRESSING MACHINES AND
Year: 1868

page_text: LETTERS PATENT to John Dendy, of the City of Manchester, in the
County of Lancaster, Silk Manufacturer, and John Howard
Worthington Biggs, of the same Place, for the Invention of "IM-
PROVED ARRANGEMENTS OF WARPS IN SIZING OR DRESSING MACHINES AND
Sealed the 11th May 1869, and dated the 13th November 1868.
PROVISIONAL SPECIFICATION left by the said John Dendy and John
Howard Worthington Biggs at the Office of the Commissioners of
Patents, with their Petition, on the 13th November 1868.
We, JOHN DENDY, of the City of Manchester, in the County of
Lancaster, Silk Manufacturer, and JOHN HOWARD WORTHINGTON
BIGGS, of the same Place, do hereby declare the nature of the said
Invention for "IMPROVED ARRANGEMENTS OF WARPS IN SIZING OR DRESSING
MACHINES AND Looms, AND IN THE MACHINERY OR APPARATUS CONNECTED THERE-
WITH," to be as follows:-
This Invention consists in an improved system of splitting the sheet
of warp in the dressing machine into several separate and distinct warps,

page_text: and in the arrangement and construction of improved warp or yarn beams
for sizing or dressing machines, looms, and similar purposes. Instead of
using only one beam in the dressing machine to receive the dressed
warps we construct a beam of various parts or subdivisions so arranged
that they wind the whole of the width of dressed warps on the beam in
various sections, each section being a distinct warp of its own, so that
when these sections are placed in a loom various widths of warp can
be woven according to the required width of the fabric; thus, if there
should be forty inches of warp in the dressing machine, the sections on
the beam may be twenty, ten, six, and four inches, or of any other
numbers that may be required.
In one mode of constructing this improved composite beam we fix in
the shaft a long key or feather, and place on the shaft drums or
bobbins of the required widths, which drums or bobbins are bushed with
metal tubes having keyways fitting the key in the shaft, and all the
drums or bobbins are pressed up close to each other by means of a fixed
collar at one end of the shaft and a spring, nut, or wedge at its other
end; or the different sections may be held together by projecting pins
fitting into holes in the flanges of the sections without the key or
feather in the rod as before mentioned; or instead of using the composite
beam in the dressing machine one sheet of warp may be subdivided and
wound on several beams of different widths according to the required
widths of the several warps. To employ the various subdivisions or
sections of the beam the shaft is removed from the dressing machine
and the sections taken off, thereby leaving the shaft for similar or
different combinations. If only two sections are required in the loom
they are placed on a shaft supported on the loom sides in the ordinary
manner, and a weighted strap, or cord, or spring is applied at the outside
end of cach section so that the tension may be regulated independently.
If three are required we adopt the following arrangement:-We separate
two of the sections with their regulating weights and insert between
them another section whose tension is regulated by its being connected
to a friction wheel by a tube passing through the tube of one of the
outer sections, and it is evident that by placing the tube of one section
on the tube of another any convenient number of sections can be used
on one shaft, the object being to be able to regulate the tension of each
section separately. We also regulate the tension of the various sections
of warps by means of breaks acting on the flanges of the said sections,
which breaks may be allowed to vibrate when the shed is opened and

page_text: closed; or we pass the warps from the various sections over or between
rollers to which friction is imparted by means of ropes connected to
springs or weights, or by means of elastic bands weighted or otherwise;.
or we pass the warps over and between rollers, some having their
peripherics covered with paper and one or more with india-rubber, and
then over a stationary rod and under a rod weighted by levers and
weights.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Dendy and John Howard Worthington
Biggs in the Great Scal Patent Office on the 12th May 1869.

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 "IMPROVED ARRANGEMENTS OF WARPS
IN SIZING OR DRESSING MACHINES AND LOOMS AND IN. THE MACHINERY OR
APPARATUS CONNECTED THEREWITH," upon the condition (amongst others)
that we, the said John Dendy and John Howard Worthington Biggs,.
our executors or administrators, by an instrument in writing under
our, or their, or one of their hands and scals, 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

page_text: Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said John Dendy and John Howard
Worthington Biggs, 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 consists in an improved system of splitting the sheet
of warp in the sizing or dressing machine into several separate and
distinct warps, and in the arrangement and construction of improved
warp or yarn beams for sizing or dressing machines, looms, and similar
purposes. Instead of using in the dressing machine a beam formed of
only one cylinder to receive the dressed warps we construct a beam of
various parts or subdivisions so arranged that they wind the whole of
the width of dressed warp on the beam in various sections, each section
being a distinct warp of its own, so that when these sections are placed
in a loom various widths of warp can be woven according to the
required width of the fabric; thus if there should be forty inches of
warp in the dressing machine, the sections on the beam may be twenty,
ten, six, and four inches, or of any other number that may be required.
In one mode of constructing this improved composite beam we fix
in the shaft a long key or feather, and place on the shaft drums or
bobbins of the required widths, which drums or bobbins are bushed
with metal tubes having keyways fitting the key in the shaft, and all
the drums or bobbins are pressed up close to each other by means of a
fixed collar at one end of the shaft and a spring, nut, or wedge at its
other end; or the different sections may be held together by projecting
pins fitting into holes in the flanges of the sections without the key or
feather in the rod as before mentioned; or instead of using the composite
beam in the dressing machine one sheet of warp may be subdivided on
several beams of different widths according to the required widths of
the several warps. To employ the various subdivisions or sections of
the beam the shaft is removed from the dressing machine and the
sections taken off, thereby leaving the shaft for similar or different
combinations. If only two sections arc. required in the loom they are
placed on a shaft supported in the loom sides in the ordinary manner,
and a weighted strap, cord, or spring is applied at the outside end of each
section so that the tension may be regulated independently. If three

page_text: are required we adopt the following arrangement:-We separate two
of the sections with their regulating weights and insert between them
another section whose tension is regulated by its being connected to a
friction wheel by a tube passing through the tube of one of the outer
sections, and it is evident that by placing the tube of one section on the
tube of another any convenient number of sections can be used on one
shaft, the object being to be able to regulate the tension of each section
separately. We also regulate the tension of the various sections of
warps by means of breaks acting on the flanges of the said sections,
which breaks may be allowed to vibrate when the shed is opened and
closed; or we pass the warps from the various sections over or between
rollers to which friction is imparted by means of ropes connected to
springs or weights, or by means of clastic bands weighted or otherwise;
or we pass the warps over and between rollers, some having their
peripheries covered with paper and one or more with india-rubber, and
then over a stationary rod and under a rod weighted by levers and
weights.
In witness whereof, I, the said John Dendy, for and on behalf of
myself and the said John Howard Worthington Biggs, have
hereunto set my hand and scal, this Eleventh day of May, in
the year of our Lord One thousand eight hundred and sixty-
nine.
