Improvements in Machinery for Sizing Yarn.
I, WILLIAM LANCASTER of Willow Iron Works, Accrington, in the County of
Lancaster, Machine Maker do hereby declare the nature of this Invention to be as
follows:
This Invention relates to Machines for purpose aforesaid and comprises, Improved
appliances for supporting and operating the rollers employed for "pressing" the yarn
as wound upon the sized beam, Improved apparatus for raising and lowering the
beam, Improved apparatus for "marking" the cuts and intervening lengths of yarn,
and to, Improved rollers or appliances for dressing the yarn so as to dispense with the
operation of brushing heretofore practised.
The improved apparatus for supporting and operating the rollers employed for
pressing the yarn upon the sized beam comprises a pair of presser rollers, of length
somewhat shorter than the width between the flanges. The rollers are carried upon
anti-friction bowls one pair of which are in the form of a cone, a second pair for
supporting the other end of the roller are in the form of double cones, that is to say,
tapered each way from midway their length. The cones are carried on supports free
to swivel on studs in cross pieces attached to a bow or bracketted arms extending
under and parallel to the yarn beam.
The pairs of cones employed for carrying and operating the presser rollers aro
arranged for one presser roller with their smaller ends, say to the right hand, the
cones carrying the other presser roller will have their smaller diameters to the left.
hand, so that as the presser rollers and cones revolve, the rollers are carried laterally
in the direction of the flanges of the yarn beam and of the smaller diameter of the
cones on which they revolve. Soon as the ends of the presser rollers are close to
flanges of the beam the double cones are reversed or turned with their smaller
diameters opposite the smaller diameters of the other cones and operate as an opposing
force, thus the presser roller is maintained in the desired position in relation to the
flanges of the beam and friction between ends of presser rollers and inside faces of the
flanges of the beam is avoided. The double cones are mounted upon a swivelling
support which can conveniently be moved by handle by the attendant when the cones
are to be reversed as described.

page_text: For purpose of lowering the beam, its presser rollers, and carrying frame, the bow
piece above referred to is carried by a stud of an arm extending from the cross shaft
which stud is also connected with the upper part of a telescopic slide or series of slides
fitting one within the other, the bottom and outer one of which is connected by
brackets with the bottom or end rail of the machine. The slides afford great facility
for lowering or raising the carrying frame, presser rollers, and yarn beam.
When it is desired to lower these the weight lever is raised whoreon the shaft makes
a partial rotation and the upper slides descend into the bottom one, or the beam and
frame can be lowered by foot of attendant applied to a treadle piece of the carrying
arm.
The requisite amount of lift and fall being obtained by means of the telescopic
slides without necessity of sinking any part below the floor level. I apply to the said
shaft adjustable friction discs by means of which the frame rollers and beam are
steadied and kept free 'from vibration or shaking.
The apparatus for marking the "cuts" and intermediate lengths of yarn for
"dhootios" comprises a change wheel on the marking shaft gearing with a carrier
wheel which drives by means of a pinion, a cross shaft, on other end of which is a
sliding toothed cone, the several diameters of which can be brought into gear with a
carrier wheel, on a stud of a radial adjustable arm. The carrier gears with a pinion
on the tappet shaft of the intermediate or dhootie marker, so as to mark any desired
length of yarn. A further change or variation can be obtained by substitution of a
different wheel for the change wheel just referred to, that is to say, one marker or
hammer will operate two three four or other number of times to one of the "cuts "
marker.
For purpose of laying the fibres of the yarn and equalizing the size thereon and to
. obviate the necessity of brushing the yarn I employ between the sizo box and the
drying cylinder two or more metal rollers on which cut or chased very fine right and
left handled worms over and under which the yarn is caused to pass and action of
which on the yarn renders unnecessary the tedious operation of brushing.

page_text: I, WILLIAM LANCASTER of Willow Iron Works, Accrington in the County of
Lancaster, Machine Maker, do hereby declare the nature of this 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 to machines, for purpose aforesaid, and comprises Improved
appliances for supporting and operating the rollers employed for "pressing "the yarn,
as wound upon
the sized beain Improved apparatus for marking the cuts, and
intervening lengths, of yarn and to Improved rollers or appliances for dressing the
yarn so as to dispense with the operation of brushing heretofore practised.
The improved apparatus for supporting and operating the rollers employed for
pressing the yarn upon the sized beam comprises a pair of presser rollers of length
somewhat shorter than the width between the flanges. The rollers are carried upon
anti-friction bowls, one pair of which are in the form of a cone, a second pair for
supporting the other end of the rollers are in the form of double cone, that is to say
-tapered each way, from midway their length-The cones are carried on supports,
free to swivel in studs, in cross pieces, attaclied to a bow or bracketted arms, extending
under and parallel to the yarn beam.
The pairs of cones, employed for carrying and operating the presser rollers, are
arranged, for one presser roller with their smaller ends, say to the right hand; the
cones carrying the other presser roller, will have their smaller diameters, to the left
hand, so that as the presser rollers and cones revolve, the rollers are carried laterally
in the direction of the flanges of the yarn beam, and of the smaller diameter of the
cones on which they revolve.
Soon as the ends of the presser rollers, are close to flanges of the beam, the double
cones are reversed, or turned with their smaller diameters opposite the smaller
diameters of the other cones, and operate as an opposing force; thus the presser roller,
is maintained in the desired position, in relation to the flanges of the beam, and friction
between ends of presser rollers, and inside faces of the flanges of the beam is avoided.
The double cones, are mounted upon a swivelling support, which can conveniently
be moved by handle, by the attendant, when the cones are to be reversed as described.
The presser rollers are carried by a frame, the bow piece is carried by a stud of an
arm, extending from the cross shaft, which stud, is also connected with the upper part
of a telescopic slide, or series of slides, fitting one within the other, the bottom and
outer one of which is connected, by brackets with the bottom or end rail of the
machine.
The slides afford great facility for lowering or raising the carrying frame and presser
rollers to the yarn beam.
When it is desired to lower these, the weight lever is raised, whereon the shaft
makes a partial rotation, and the upper slides descend into the bottom one, or the
beam and frame can be lowered by foot of attendant applied to a treadle piece of the
carrying arm.

page_text: The requisite amount of lift and fall, being obtained, by means of the telescope
slides, without necessity of sinking any part below the floor level. 1 apply to the said
shaft, adjustable friction discs, by means of which the frame, rollers, and beam, are
steadied and kept free from vibration or shaking.
The apparatus for marking the "cuts," and intermediate lengths of yarn, for
"dhooties," comprises a change wheel, on the marking shaft, gearing with a carrier
wheel, which drives, by means of a pinion, a cross shaft, on other end of which is a
sliding toothed cone, the several diameters, of which can be brought into gear, with a
carrier wheel, on a stud of a radial adjustable arm. The carrier, gears with a pinion,
on the tappet shaft, of the intermediate or dhootie marker, so as to mark any desired
length of yarn.
A further change or variation, can be obtained, by substitution of a different wheel,
for the change wheel just referred to, that is to say-one marker or hammer will
operate two, three four, or other number of times to one of the "cuts "marker.
For purpose of laying the fibres of the yarn, and equalizing the size thereon, and to
obviate the necessity of brushing the yarn, I employ between the size box, and the
drying cylinder two, or more metal rollers, on which is cut or chased, very fine right,
and left handled worms, over and under which the yarn is caused to pass, and action
of which, on the yarn renders unnecessary the tedious operation of brushing.
Such being the nature, and object of this my said Invention, the following is a
complete description of same, reference being had to the accompanying drawings:-
the presser roners.
Fig. 2 is an end elevation of Fig. 1.
Fig. 3 is a plan view of the presser rollers, carrying cones and telescopic slide.
Fig. 4 is an enlarged end view of presser rollers and cones.
Fig. 5 is a plan of Fig. 4.
Fig. 6 cross section of marking mechanism.
Fig. 7 a side elevation of above.
Fig. 8 a plan of Fig. 6.
Fig. 9 is a side elevation, of the improved rollers, for laying the divergent fibre of
the yarn and equalizing the size thereon.
Fig. 10 is a plan of Fig. 9.
At 1-2 are the presser rollers, of length, somewhat shorter than the length between 3
the flanges of the warp beam 3, the rollers 1-2 are carried on the cones 4, 5, 6, 7,
and the anti-friction runners 8-9, the pair 5, 7 are as shewn double cones-that is-
tapering each way from midway their length, and are carried on supports 10, free to
swivel on the pins 11, in cross pieces 12, carried by bow arms 13, extending under
and parallel to the yarn beam.
At 14 is a hand lever, by means of which and the slot and pin 15, the cones 5-7-
can readily be set with the smaller ends, in either direction, so as first to traverse the
rollers 1, 2 in opposite directions as shown at Fig. 2 until the ends of the said rollers,
reach the flanges of the beam 3, whereon the handle 14 will be turned over to the
opposite side reversing the ends of the cones 5-7 in contact with the rollers 1, 2 and
the latter will cease to traverse either way, but maintain the position shewn by Fig. 1
and Fig. 2-the actual contact and rubbing of the ends of the rollers 1-2-against the
inside of the flanges of the beam 3 being avoided, whilst the ends of the rollers remain
close thereto.
The bow piece 13 and presser rollers 1-2-are carried on a stud and arm 15, 5
extending from the cross shaft 16, which arm, is connected to the upper plate 17,
which together with like plate 18, slide telescopically in, and out of the frame 19, the
latter being connected by bracket 20, with the framing of the machine. The raising
and lowering the frame and presser rollers, being effected through the agency of the

page_text: lever, and weight 21, or the lowering may be affected through application of the foot
to the end 22 of the lever 15.
All vibration of the beam, and carrying frame, is prevented by the friction
plates 23-24, the latter being fast to the end frame of the machine, the plate 23
sliding on the shaft 19 on a key, and being set by the handle 25, and spring 26. In
case of light beams the weight 21 can be dispensed with when the friction desired is
applied.
The apparatus for marking the "cuts" and intermediate lengths of yarn, for
"dhooties" comprises a change wheel 27, on the marking shaft 28, gearing with a
carrier wheel 30, which drives by means of a pinion 31 a cross shaft 32, on other end
of which is a sliding toothed cone 33, the several diameters of which can be brought
into gear with a carrier wheel 34 on a stud of a radial adjustable arm 35.
The carrier gears with a pinion 36, on the tappet shaft 37, of the intermediate or
"dhootie" marker 38, so as to mark any desired length of yarn. A further change
or variation can be obtained by substitution of a different wheel for the change
wheel 27, just referred to-that is to say-one marker or hammer will operate two,
three, four, or other number of times to one of the "cuts" marker, 39 and 40 being
the colour boxes; 41 is the measuring roller, and 42 the rod for throwing in and out
of gear.
For purpose of laying the divergent fibres, to the body of the yarn, and equalizing
the size thereon, I employ the rollers 43-44, on one of which is cut a right handed
screw or thread, the other having a left handed thread, these rollers are to be placed
in any convenient position, between the sow box and the drying cylinder 45, being
coupled by the gear wheels 46-47 and driven by the strap, and pulleys 48, from the
side shaft or other going part.
Having thus fully described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
Firstly The cones 4-5-reverse and reversible 5. 7. together with the presser
rollers 1-2--in combination, and for purpose herein described and illustrated.
Secondly The telescopic slide 20, 21, and 22, arm 18, and the support 10 for
carrying the presser rollers 1-2 whether the latter be supported on conical or
cylindrical bearers in combination and substantially as described.
Thirdly In a machine for sizing yarn, a presser roller, carrying frame, a supporting
shaft such as 19 having a controlling frictional appliance such as 23, 24 all in com-
bination for purpose set forth.
Fourthly The construction, combination, and arrangement of parts and gear for
operating the markers as described and illustrated by annexed drawings Figs. 6, 7,
and 8.
Fifthly The reverse screwed or chased rollers applied, and used between and in
combination with the sow or size box, and drying cylinder or drying cylinders of
machines for purpose described.
