Year: 1881

page_text: LETTERS PATENT to Aspdon Pickup Dickinson, Machine Maker, and William
Rossetter; Mechanic, both of Blackburn, in the County of Lancaster, for an
Invention of "IMPROVEMENTS IN SLASHERS' OR SIZING MACHINES."
PROVISIONAL SPECIFICATION left by the said Aspden Pickup Dickinson
and William Rossetter at the Office of the Commissioners of Patents on the
19th November 1881.
ASPDEN PICKUP DICKINSON, Machine Maker, and WILLIAM ROSSETTER, Mechanic,
both of Blackburn, in the County of Lancaster. "IMPROVEMENTS IN 'SLASHERS'
OR SIZING MACHINES."
The first part of our Invention consists in an improved apparatus for pressing or
levelling the yarn while being wound on the yarn beam, and consists in the use of
two presser rollers, one made in two parts connected in the middle by a right and
left hand screw, by turning which the two parts of the roller are caused to approach
or recede from each other until they fit exactly between the flanges of the yarn
beam; the second presser roller must be shorter than the distance between the
flanges, but longer than the space between the two parts of the other roller, so that
it may press on the yarn that would otherwise receive no pressure; these rollers
are placed by preference below the yarn beam on a level with each other and
equidistant from the axis of the yarn beam; they are mounted on anti-friction
bowls fitted on a vertically sliding bracket actuated by a rack and wheel, or
otherwise.
The second part.of our Invention consists in improvements in driving the side
shaft which communicates the slow motion to the sizing machine. We dispense
with the bevel wheel on the driving shaft which receive motion from it, and in
place of these we employ a worm connected to or cast with a pulley, which pulley
and worm run loose on the driving shaft; on the side shaft above the driving
shaft we fit a worm wheel which gears into the worm and (with the side shaft)
receives motion from it when the driving belt is moved on to the pulley connected
[Price Gd1

page_text: to the worm. The worm wheel is fitted on a feather key so that it may be moved
out of gear with the worm when desired.
The third part of our Invention consists in improved methods of stopping the
rotation of the yarn beam. In order to stop the drawing roller we lengthen the
cone drum shaft and fit the pinion on it on a feather key, so that it may be
readily moved out of gear with the wheel on the drawing roller shaft by a suitable
lover; the stopping of the drawing roller would also stop the yarn beam. To stop
the rotation of the yarn beam only, we fit the bearings of the drawing roller shaft
in slots concentric to a shaft extending across the machine on which are levers to
move the said bearings till the wheel on the drawing roller shaft is out of gear
with the wheel between the friction plates which communicate motion to the
yarn beam.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Aspden Pickup Dickinson and William Rossetter in the Great Seal
Patent Office on the 19th May 1882.

OR SIZING MACHINES."
The first part of our Invention consists in an improved apparatus for pressing or
levelling the yarn while being wound on the yarn beam, and consists in the use of
two presser rollers, one made by preference in two parts connected in the middlo
by a right and left hand screw, by turning which the two parts of the roller are
caused to approach or recede from each other until they fit exactly between the
flanges of the yarn beam; the second presser roller must be shorter than the
distance between the flanges, but longer than the space between the two parts of
the other roller, so that it may press on the yarn that would otherwise receive no
pressure; these rollers are placed by preference below the yarn beam on a line
with each other, and equidistant froin the axis of the beam; they are mounted on
antifriction bowls fitted on a vertically sliding bracket actuated by a rack and
wheel, or otherwise.
The second part of our Invention consists in improvements in driving the side
shaft which communicates the slow motion to the sizing machine. We dispense
with the bevel wheel on the driving shaft and the bevel wheel and shaft which
receive motion from it, and in placo of these we employ a worin connected to or
cast with a pulley, which pulley and worin run loose on or are otherwise fitted on
or connected with the driving shaft; on the side shaft above the driving shaft we
fit a worm wheel which gears into the worm and (with the side shaft) receives
motion from it when the driving belt is moved on to the pulley connected to the
worn; the worm wheel is fitted on a feather key so that it may be moved out of
gear with the worm when desired.

page_text: The third part of our Invention consists in an improved method of stopping the
rotation of the drawing roller and the rotation of the yarn beam. In order to stop
the drawing roller we lengthen the cone drum shaft and fit the pinion on it on a
fenther key, so that it may be readily moved out of gear with the wheel on the
drawing roller shaft by a suitable lever; the stopping of the drawing roller would
also stop the yarn beam.
And in order that our Invention may be fully understood and readily carried
into effect, we will describe the accompanying two Sheets of Drawings, reference
being had to the figures and letters marked thereon.
On Sheet 1, Fig. 1 represents part of a "slasher" or sizing machine to which our
improvements for pressing or levelling the yarn on the yarn bean are applied;
Fig. 2 is an end view of the same.
a is the presser roller made in two parts; b is the presser roller which is made
of one piece longer than the distance between the two parts of a, but shorter than
the distance between the flanges of the yarn beam; the two parts of a aro
connected by a shaft c, on which a right and left hand screw are formed, having
lock nuts d, d, to secure the two parts of the roller when adjusted. Instead of the
screwed shaft c we connect the two parts of the roller a by a shaft, on which are
two spiral springs which press the two parts of the roller outward. The presser
rollers a and b turn on antifriction rollers e carried in brackets f supported on a
cross bar mounted on a vertically sliding bar h, on which is a rack actuated by
a pinion i on a shaft i', on which is a chain wheel 2 turned by a weighted chain
passing over a chain wheel (not shown) fitted in any convenient position above the
machine. Instead of employing the sliding bar h we connect the cross bar directly
to a lever, as shown on Fig. 4; in this case the cross bar is pivoted to the lever in
order that the cross bar may move so as to maintain an equal pressure of tho
rollers on the yarn as its diameter on the beam increases.
ง
.
Fig. 3 is a plan, and Fig. 4 an end elevation, showing a modification of this
part of our Invention. In this case we employ two presser rollers a' nnd b¹, cach
made of one piece shorter than the distance between the flanges of the yarn beam ;
each of these presser rollers is mounted on antifriction rollers e, e, the bearings of
which are moved by set screws j, j, nearer to or further from the axis of the yarn
beam, so as to cause the end of one presser roller to run in contact with one flange
of the yarn beam, and the end of the other presser roller to run in contact with.
the other flange of the open beam. The antifriction rollors turn on studs fitted on
two brackets supported by a cross bar g', pivoted on a stud that connects the
cross bar to a vibrating lever & fixed on a square shaft k, on which is also fixed a
weighted lever to give the desired pressure to the yarn on the beam. The brackets
ff may be fitted on slides at the ends of the cross bar g, so that they may movo.
nearer to or further from the centre on which the lever vibrates, according to the
diameter of the yarn on the yarn beam.
"
On Sheet 2, Fig. 5 is a side elevation; Fig. 6 is a front elevation; and Fig. 7 is
a plan of part of a "slasher or sizing machine to which the second and third parts
of our Invention are applied, although we show part of a machine in which cone
drums are used; our Invention is also applicable to machines in which cone drums
are not used.
The cone druin 7 is mounted on a shaft 8, so that the drum and shaft may turn
independently of each other. On the shafts are fixed the pulleys t and L', and
the pulley runs loose on the shaft. We form a clutch at the end of the drum r.
We fit a boss & on which is a corresponding clutch on a feather key on the shaft 8,
and connect this boss by a fork to the shipping rod, so that when the driving belt
is moved on to the pulley & the clutch is disengaged and the drum will not turn
with the shafts, and when the belt is moved on to the pulley t¹ the clutch on the
boss is moved into contact with the clutch on the druin r, and causes it to turn
with the shaft s. On one end of this shaft is fixed the worm u gearing into the
worm wheel v loose on the side shaft v'. On one side of the worm wheel vis a
clutch, and a clutch on the boss w that slides on a feather key fixed on the side

page_text: shaft takes into the clutch on the worm wheel, thus causing the shaft and worm
wheel to turn together when the driving belt is moved on to the pulley t. The
boss w is actuated by a fork on a rod connected to the shipping lever, to which tho
strap guide which moves the driving belt is also connected; or instead of this
arrangement the cone drum r is mounted on a hollow shaft, on which is fixed the
pulley ; through this hollow shaft is passed a shaft, on one end of which is fixed
the pulley t, and on the other end is fixed the worm u gearing into the worm
wheel to which motion is imparted, as before described.
a is the pinion fittod on a feather key on the front cono drum shaft y that
communicates motion to the drawing roller. We lengthen the shaft y to allow
the pinion to be moved by a lever = connected to the shipping rod out of gear
with the wheel on the drawing roller shaft, when the belt is inoved on to the
pulley t to stop the drawing roller and the yarn beam, and we place a spiral spring
on the shaft y to press the pinion into gear with the wheel when the shipping
rod is moved to place the belt on the pulley t¹ or t².
Having stated the nature of our Invention and described the manner of
performing the same,
Wo declare that wo claim,
1. The use of two presser rollers, substantially as and-for the purpose herein
described and shown.
2. The improved method of driving the side shaft v', substantially as herein
described and shown.
3. The mode of stopping the drawing roller by sliding the pinion x out of gear
with the wheel on the drawing roller, as herein described.
In witness whereof, I, the said William Rossetter; for myself and on behalf of
the said Aspden Pickup Dickinson, have hereunto set my hand and seal,
this Seventeenth day of May, One thousand eight hundred and eighty two.
