Improvements in Machines Employed in Dyeing, Sizing, Washing,
and Wringing Hanks.
I, JAMES ROBERTSHAW, of 3 & 5, Simpson Street, Angel Street, Manchester, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements on an invention for which Letters Patent
No. 12002, dated October 9th 1885, were granted to me.
In the said invention the rotary fallers, on which the hanks are placed for the
purpose of being drawn through the liquid, are geared up with the driving wheel of
the reversing gear employed in such machines for the purpose of reversing the rotation
of the fallers, by means of spur wheels carried by a frame in such a manner that
whatever the height of the fallers may be, they will be always in gear, for the purpose
of continuing the rotation of the fallers whilst raising the banks out of the liquid,
and facilitating the dyeing, sizing, or washing of hanks of any length.
The object of this invention is to dispense with the said spur-wheel gearing and
frame carrying the same, and to provide means whereby the driving of the fallers
at any required height will be effected more simply and better than heretofore.
This I attain in two different ways according to circumstances. The first method
consists in fixing to the frame carrying the fallers an arm pointing downwards and
carrying at its lower extremity a guide pulley revolving loosely on a stud.
To the wheel from which the motion from the fallers has heretofore been obtained,
and which forms part of the aforesaid reversing gear, I connect a chain wheel
respectively, and over these two chain wheels and the guide pulley, I place tightly
an endless chain, whereby the rollers are kept continuously in gear with the wheel
of the said reversing gear. The second method consists in employing on the latter
wheel a worm, and on one of the faller shafts a worm wheel.

page_text: On the side of this worm and worm wheel I employ a shaft to transmit rotary
motion from the said worm to the worm wheel on the faller shaft by furnishing the
said shaft with a worm and worm wheel, gearing respectively into the aforesaid worm
wheel & worm.
This shaft at its lower end is mounted in a stationary bearing, and near its upper
end in a bearing fixed to and moving with the faller bracket or frame.
This bearing is so formed as to cause the worm to slide on the said shaft, which
latter is furnished with a key so as to be always in gear with the worm wheel fixed
on the faller shaft, and continuously rotate the same at any height the faller may be
required to be rotated.

Improvements in Machines Employed in Dyeing, Sizing, Washing,
and Wringing Hanks.
I, JAMES ROBERTSHAW of 3 & 5 Simpson Street, Angel Street, Manchester in the
County of Lancaster, Machinist, 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 improvements in an invention for which Letters Patent
No. 12002, dated October 9th 1885, were granted to me.
In the said invention the rotary fallers, on which the hanks are placed for the
purpose of being drawn through the liquid, are geared up with the driving wheel of
the reversing gear employed in such machines for the purpose of reversing the
rotation of the fallers, by means of spur wheels carried by a frame in such a manner
that whatever the height of the fallers may be, they will be always in gear, for the
purpose of continuing the rotation of the fallers whilst raising the hanks out of the
liquid, and facilitating the dyeing, sizing or washing of hanks of any length.
The object of this invention is to dispense with the said spur wheel gearing and
frame carrying the same, and to provide means whereby the driving of the fallers
at any required height will be effected more simply and better than heretofore.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the figures.
Fig. 1 is a back view of the whole of the machine showing one method, and Fig. 2
is a detached back view showing another method of applying my improvements
thereto.
a is the vat, b the fallers, c the reversing gear from which the fallers are driven.
d the faller wheels, e the driving shaft, the reversing motion for the faller lifting
gear.
In carrying out my invention I attain the object aforesaid in two different ways
according to circumstances.
The first method, see Fig. 1, consists in fixing to the frame g carrying the fallers b
an arm 7 pointing downwards and carrying at its lower extremity by means of a
weighted fever a guide pulley 1, revolving loosely on a stud m.
To the wheel n from which the motion for the fallers b has heretofore been obtained,
and the wheel which forms part of the aforesaid reversing gear c, I connect a chain
wheel o & p respectively, and over these two chain wheels o & p, and the guide
pulley I place tightly an endless chain q, whereby the fallers bare kept continually
in gear with the chain wheel o of the said reversing gear e, whatever the position of
the fallers may be, see dotted lines, the tension being obtained by means of the weighted
lever k, see dotted lines.

page_text: The second method, see Fig. 2 consists in employing on the wheel n', a worm »,
and on one of the faller shafts or intermittent wheels d driving the same a worm
wheel s.
On the side of this worm and worm wheel & s I employ a shaft t to transmit
rotary motion from the said worm to the worm wheels on the faller shaft by
furnishing the said shaft with a worm u and worm wheel gearing respectively into
the aforesaid worm wheels and worm r.
This shaft at its lower end is mounted in a stationary bearing w, and. near its
upper end in a bearing a fixed to and moving with the faller bracket or frame g.
This bearing a is so formed as to cause the worm to slide on the said shaft t,
which latter is furnished with a key so as to be always in gear with the worm wheel
fixed on the faller shaft, and continuously rotate the same at any height the faller may
be required to be rotated, see dotted lines.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is
In machines employed in dyeing, sizing, washing and wringing hanks,
1st. The faller frame g carrying a bracket or arm / moving therewith, and provided
with a guide pulley in combination with a chain pulley p, fixed on one of the faller
shafts, and chain pulley o, rotated by the reversing gear c and chain q riding over
pulleys, o &p, substantially as and for the purpose specified.
2nd. The combination of a shaft t provided with a worm and worm wheel and s,
gearing into a worm wheel u and worm fixed respectively on the faller shaft or
intermittent wheel d, driving the same and reversing gear e, substantially as and for
the purpose specified.
