"IMPROVEMENTS IN OR APPLICABLE TO SECTIONAL WARPING AND BEAMING
MACHINES."
This Invention relates to sectional warping and beaming machines, and has for
its object the equalization of the diameter of all the sections of a warp and of the
length and tension of the yarn of each section.
In carrying out this Invention we place two similar sectors upon the presser
shaft, one of which is fixed thereon while the other is free. Both the sectors are
capable of being pinned or bolted together; the fixed sector has upon its rim a
graduated scale, while the free sector carries an index finger or pointer. The loose
sector is actuated by means of a worm carried on a small shaft. On another
parallel small shaft is a ratchet wheel or its equivalent to which intermittent rotary
motion may be given by means of a catch or pawl on the section shaft, the catch or
pawl being so arranged that it may be withdrawn when it is required to put the
apparatus out of gear. The ratchet and worm shafts are geared together by means
of change wheels, and the framing in which they have their bearings is secured to a
convenient portion of the machine.
The method of using this Invention may be described as follows:-The apparatus
is put out of gear by withdrawing the driving catch or pawl, and the sectors are
disengaged from each other, the pointer of the free sector being made to point to
zero on the graduated scale upon the fixed sector. The first section of the warp is

page_text: then filled in with the required length of yarn in the usual manner. During this
operation the free sector will be held stationary by the worm gearing into it, while
the fixed sector will move with the presser shaft. When the section has been filled
in the pointer on the one sector will be found to point to a division on the graduated
scale, the number of which reckoned from zero will indicate the number of teeth
required for the change wheel on the ratchet shaft. The number of teeth required
for the remaining change wheel which is fixed on the worm shaft is found by
dividing the number of revolutions made by the section shaft while filling in
the first section by ten or some other number governed by the magnitude of the
divisions on the graduated scale and the number of teeth or projections on the
ratchet wheel or its equivalent. The change wheels having been fixed in their
relative positions and put into gear by the intervention of an idle or intermediate
change wheel, the graduated sector is brought back to zero, the two sectors are
pinned or bolted together, and the apparatus is put into gear.
and
A positive and uniform motion is given by the section shaft to the ratchet wheel
or its equivalent, and this is transmitted by means of the change wheels, worm,
sector to the presser, so that the presser always occupies precisely the same position
relatively to the centre of the section shaft for the same number of revolutions, and
all the sections have therefore the same number of revolutions and equal lengths
and tension of yarn irrespective of any variation in the size or count or of the
number of ends.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Christmas Sewell, Eustace Hulton, and John Bethel in the
Great Seal Patent Office on the 14th June 1881.

" IMPROVEMENTS IN OR APPLICABLE TO SECTIONAL WARPING AND BEAMING
MACHINES."
This Invention relates to sectional warping and beaming machines, and has for
its object the equalization of the diameter of all the sections of a warp, and of the
length and tension of the yarn of each section.
In carrying out this Invention we place two similar sectors upon the presser
shaft, one of which is fixed thereon, while the other is free. Both the sectors are
capable of being pinned or bolted together; the fixed sector has upon its rim a
graduated scale, while the free sector carries an index finger or pointer. The loose
sector is actuated by means of a worm carried on a small shaft. On another parallel
small shaft is a ratchet wheel or its equivalent, to which intermittent rotary motion
may be given by means of a catch or pawl on the section shaft, the catch or pawl
being so arranged that it may be withdrawn when it is required to put the apparatus
out of gear.
The ratchet and worm shafts are geared together by means of change

page_text: wheels, and the framing in which they have their bearings is secured to a convenient
portion of the machine.
The method of using this Invention may be described as follows:-The apparatus
is put out of gear by withdrawing the driving catch or pawl, and the sectors are
disengaged from each other, the pointer of the free sector being made to point to
zero on the graduated scale upon the fixed sector. The first section of the warp is
then filled in with the required length of yarn in the usual manner. During this
operation the free sector will be held stationary by the worm gearing into it, while
the fixed sector will move with the presser shaft. When the section has been filled
in the pointer on the one sector will be found to point to a division on the graduated
scale, the number of which reckoned from zero will indicate the number of teeth
required for the change wheel on the ratchet shaft. The number of teeth required
for the remaining change wheel which is fixed on the worm shaft is found by
dividing the number of revolutions made by the section shaft while filling in the
first section by ten or some other number governed by the magnitude of the divisions
on the graduated scale and the number of teeth or projections on the ratchet wheel
or its equivalent. The change wheels having been fixed in their relative positions
and put into gear by the intervention of an idle or intermediate change wheel, the
graduated sector is brought back to zero, the two sectors are pinned or bolted
together, and the apparatus is put into gear.
A positive and uniform motion is given by the section shaft to the ratchet wheel
or its equivalent, and this is transmitted by means of the change wheels, worm, and
sector to the presser, so that the presser always occupies precisely the same position
relatively to the centre of the section shaft for the same number of revolutions, and
all the sections have therefore the same number of revolutions and equal lengths
and tension of yarn irrespective of any variation in the size or count or of the
number of ends.
And in order that this Invention may be more readily understood and carried
into practical effect, we have hereunto annexed a Sheet of Drawings illustrative of the
Invention, and will now proceed to describe the same, reference being had to such
Drawings and the letters of reference marked thereon.
Fig. 1 is a side view, Fig. 2 is a front view, and Fig. 3 is a plan showing the
improvements; Fig. 4 is a front view of the sectors drawn separately with the
finger at zero.
In all the views similar letters of reference are used to denote similar parts.
The two sectors A, B, are placed upon the presser shaft C. The sector A is
keyed or otherwise secured to the presser shaft, and has upon its rim a graduated
scale. The sector B is free to rotate upon the presser shaft, and carries upon its
periphery an index finger D, which passes over and points out the divisions on the
graduated rim of the sector A. The sector B has formed upon its rim a series of
teeth into which the worm E gears, and through which the sector receives a rotary
motion on the presser shaft. The two sectors are capable of being secured together
in any position relatively to each other by means of a bolt and nut passing through
corresponding slots in each sector.
The motion of the section shaft is imparted intermittently to the apparatus by
means of a pawl F actuated from the section shaft by means of the excentric and
rod G, and the lever H. The pawl F, which may be withdrawn when it is desired
to put the apparatus out of gear, takes into and drives a ratchet wheel I which is
fixed upon a shaft parallel with the shaft upon which the worm E is fixed. The
ratchet and worm shafts are geared together by means of a train of change
wheels K, K', K². Upon the ratchet shaft is keyed a worm which gears into a
small worm wheel L, upon the axis of which is fixed an index finger which points
to the divisions upon a graduated disc M. The positions of the graduated disc and
of the index finger may be reversed, that is to say, the disc may be fixed on the
worm wheel shaft while the index finger maintains a stationary position.
If the apparatus is put out of gear and the two sectors are unbolted or freed
from each other, the index finger of one having first being placed at zero on the

page_text: graduated rim of the other, and a section of the warp is filled to the required
length in the usual manner, it will be found that the toothed sector B having been
held in position by the worm E, which being out of gear has remained stationary,
and the graduated sector A having partaken of the motion of the presser shaft, the
pointer will then point to a division on the rim, the number of which reckoned
from zero will indicate the number of teeth in the change wheel which is requisite
to give the proper number of revolutions to the worm E, in order by its means to
give the same amount of motion to the sector B as the sector A had received when
the first section was run off. If then the two sectors are securely bolted together
and a second section is filled in with warp, it will be evident that when the same
length has been filled in, or, in other words, when the same number of revolutions
have been made, the presser will occupy the same position as on the completion of
the first section, and that therefore the second and all succeeding sections will have
equal lengths and tensions of yarn.
The number of revolutions made by the section shaft during the winding of the
first section may be ascertained by means of a counter, in which case the apparatus
is put out of gear by withdrawing the pawl, or it may be determined by means of
the worm and worm wheel L and the graduated disc M. In the latter case the
apparatus is put out of gear by the removal of the intermediate change wheel K³,
the pawl remaining in gear.
In practice we so arrange the magnitudes of the divisions on the graduated rim
of the sector and the disc M that the numbers of the change wheels required may
be directly indicated without calculation.
In place of actuating the presser shaft by the worm and sector herein before
described, a train of suitable toothed wheels driven from the section shaft and
driving the presser shaft may be employed. This train is so arranged that the
requisite change wheels for governing the diameter of the section can be introduced
as already described. In this modified arrangement a reversing gear must be
introduced, so that the presser will always recede from the centre of the section
when the machine is working irrespective of the direction in which the warp is
being wound on.
Having thus described the nature of our said Invention, and the manner in
which the same may be performed, we desire it to be understood that we do not
limit ourselves to the precise details shown and described, as the same may be
varied without departing from the nature of our Invention, but we claim for the
purpose of securing for the various sections of a warp, the same number of
revolutions and equal lengths and tensions of the yarn irrespective of any
variation in the size or count of the yarn or of the number of ends; the use of change
wheels alone or in combination with the worms, worm wheels, sectors, and other
apparatus, substantially as hereinbefore described and indicated on the accompanying
Drawings.
In witness whereof, I, the said John Christmas Sewell, on my own behalf
and on behalf of the said Eustace Hulton and John Bethell, have hereunto
set my hand and seal, this Eleventh day of June, in the year of our Lord
One thousand eight hundred and eighty one.
JOHN CHRISTMAS SEWELL. (L.S.)
