Improvements in Machines for Bleaching, Dyeing, Sizing, and
Scouring Yarn in the Hank or Warp, and also for Fabrics.
I, SAMUEL SPENCER, of Narrow Lane, Whitefield, near Manchester, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in machines for bleaching, dyeing, sizing
and scouring yarn in the lank or warp and also for fabrics.
This invention has for its object, firstly, to simplify the faller lifting mechanism;
secondly, to provide means whereby the yarn ends are kept straight and the
hanks, warp or fabric is prevented from running into each other; and thirdly, to
afford facilities for bleaching, dyeing, sizing or scouring yarn in the hank or warp
and fabric in the same machine.
To this end my improvements consist in the first place in fixing to the faller
frame near each end thereof a shank arranged to slide in suitable bearings fixed
to the back of the vat. These shanks have attached a strong rail, tied to the
faller frame by means of stay rods, which rail rests and is acted upon by two
crank studs, fixed respectively on worm wheels mounted on studs at the back of the
vat. The said worm wheels are rotated by means of two worms, which are fixed
on the driving shaft suitably mounted in bearings at the back of the vat, which
worm wheels and studs cause the faller frame to be raised and lowered alternately,
on the strap being placed onto the fast pulley keyed at one end of the driving
shaft. Two loose pulleys are also provided thereon, one of which has attached a
friction wheel serving to impart rotary motion to the fallers and the other to
receive the strap when the machine is at rest. A corresponding friction wheel is
fixed onto a short shaft suitably mounted on the faller frame, which friction
wheel, on the fallers being lowered, is brought into gear with that on the said
loose pulley and out of gear on being raised. In lieu of interrupting the rotation
of the fallers when raising the same, suitable gearing may be provided, such as a
chain and wheels to continue the rotation of the fallers on and after being raised
or lowered. From the aforesaid short shaft rotary motion is imparted by means of
worm wheel gearing to one of the faller shafts, which motion is communicated
thereby and by spur wheel gearing to the other fallers.
My improvements consist in the second place in providing the faller frame at
each end with an arm projecting across the vat and arranged to carry a suitable
number of longitudinal rods placed between the hanks, warp, or fabrics, for the
purpose of preventing the same from running into each other. In the lower end
of the hanks I employ one or two metal rollers, which through the action of the
hanks are rotated continuously, and owing to their weight keep the ends of the
hanks straight.
My improvements consist in the third place in making the described machine
applicable for bleaching, dyeing, sizing or scouring warp or fabric, by substituting
the fallers used for hank bleaching, dyeing, sizing or scouring aforesaid, and
particularly described in my Patent, No. 1954 of 1888, by ordinary rollers in com-
bination with bottom rollers, carried by a frame attached to the faller frame.
warp or fabric to be dyed, etc., which is made endless, is threaded cross wise on
each set of fallers, from one end thereof to the other, where it is run over a guide
and a tension pulley.
The
The warp or fabric may be run through one or more pair of squeezing rollers,
so as to thoroughly impregnate the same with liquor, which is suitably run back

page_text: into the vat. By this means I am enabled to examine any part of the warp or
fabric when under treatment by simply lifting the fallers out of the vat, which
heretofore has not been the case.

COMPLETE SPECIFICATION.
Improvements in Machines for Bleaching, Dyeing, Sizing, and
Scouring Yarn in the Hank or Warp, and also for Fabrics.
1, SAMUEL SPENCER, of Narrow Lane, Whitefield, near Manchester, in the
County of Lancaster, Engineer, 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 :—
My invention relates to improvements in machines for bleaching, dyeing, sizing
and scouring yarn in the hank or warp and also for fabrics.
This invention has for its object, firstly, to simplify the faller lifting mechanism;
secondly, to provide means whereby the yarn ends are kept straight and the
hanks, warp or fabric is prevented from running into each other; and thirdly, to
afford facilities for bleaching, dyeing, sizing or scouring yarn in the hank or warp
and fabric in the same machine.
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 various figures.
Fig. 1 is a back view, Figs. 2 & 3 are front views and Fig. 4 is a vertical section
of my improved machine for bleaching, dyeing, sizing and scouring yarn in the
hank or warp and also for fabrics.
a is the rat, & the driving shaft, c the fallers, d the faller frame.
In carrying out this invention and referring to Figs. 1, 2 & 4, my improvements
consist in the first place in fixing to the faller frame d, near each end thereof a
shank e, arranged to slide in suitable bearings f, fixed to the back of the vat a.
These shanks e have attached, by means of the brackets f", a strong rail g, tied to
the faller frame d by means of stay rods h, which rail g is acted upon by two crank
studs i, fixed respectively on worn wheels mounted on studs at the back of the
vat d.
The said worm wheels are rotated by means of two worms m, which are fixed
on the driving shaft suitably mounted in bearings n, at the back of the vat a,
which worm wheels & cause the studs to revolve in the direction of the arrow &
bring the same into contact with the rail g of the faller frame d, which raises the
latter into position shown in Fig. 4, and afterwards lowers it to its normal position,
on the strap being placed onto the fast pulley o keyed at one end of the driving
shaft b. Two loose pulleys 7, y are also provided thereon, the pulley p having
attached a friction wheel serving to impart rotary motion to the fallers c and the
pulley to receive the strap when it is desired to stop the machine. A corre-
sponding friction wheels is fixed onto a short shaft, suitably mounted on the
faller frame d, which friction wheels, on the fallers c being lowered, is brought
into gear
with the wheel on the loose pulley and out of gear on being raised.
In lieu of interrupting the rotation of the fallers e when raising the same, suitable
gearing may be provided, such as a chain u and wheels v, see Fig. 2, to continue
the rotation of the fallers con and after being raised or lowered. From the
aforesaid short shaft rotary motion is imparted by means of worm wheel
gearing & to one of the faller shafts y, see Fig. 4, which motion is com-
municated thereby and by spur wheel gearing a to the other fallers c.
My improvements consist in the second place in providing the faller frame dat
each end with an arm projecting across the vat a, and arranged to carry a

page_text: suitable number of longitudinal rods d³, placed between the hanks z, warp or
fabrics on cross frames depending from the arms d¹, for the purpose of
preventing the same from running into each other. In the lower end of the
hanks I employ one or two metal rollers cl, which through the action of the hanks
are rotated continuously and owing to their weight keep the ends of the hanks
straight.
=
The corners in the bottom of the vat a, I form with a bevel a¹, so as to cause
the metal rollers c', when the hank descends to rest and partly lock on the
same and when raised from it to give the end thereof a swill in the liquor. Along
cach side of the vat al apply on the end of the rollers el a weighted rail e which
serves to stretch the hanks on being lifted by the crank fallers b.
Referring more particularly to Figs. 2 & 3, my improvements consist in the
third place in making the described machine applicable for bleaching, dyeing,
sizing or scouring warp or fabric, by substituting the fallers used for hank
bleaching, dyeing, sizing or scouring aforesaid, and particularly described in my
Patent, No. 1954 of 1888, by ordinary rollers in combination with bottom
rollers, carried by a frame d, d³, & do, attached to the faller frame d. The
warp or fabric to be dyed, etc., which is made endless, is threaded cross wise on
each set of fallers c³ & cor open as shown in the drawings, from end to end, where
it is run over guide and tension pulleys .
The warp or fabric may be run through one or more pair of squeezing
rollers so as to thoroughly impregnate the same with liquor, which is suitably
run back into the vat a. By this means I am enabled to examine any part of the
warp or fabric :' when under treatment by simply lifting the fallers or roller c³
& out of the vat a, by means of the lifting arrangement described, which here-
tofore has not been the case.
I may remark that the warp or fabric is drawn through dye, etc., liquor by the
top roller c by reason of the same being geared up and not by the squeezing
rollers as is the case in other machines, which is a great advantage as there being
less drag on the yarn and therefore less liable to injury.
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 for bleaching, dyeing, sizing and scouring yarn in the hank or
warp and also for fabric,"
1st. The general arrangement and combination of parts constituting my improve-
ments, operating in the manner substantially as and for the purpose set forth.
2nd. The combination of a crank motion i, k, m, with a faller frame d, h, y,
adapted to raise and lower the latter, substantially as and for the purpose set
forth.
3rd. The combination with the faller frame d of a frame d', d adapted to carry
longitudinal rods placed between the hanks, warp or fabrics ¹ for the purpose
of keeping the ends thereof straight, substantially as set forth.
4th. The combination with the faller frame d of a frame d', carrying rollers c',
adapted to extend the warp or fabric passed over and driven by the top fallers
in an endless form and guide the same through the liquor in the vat a, all sub-
stantially as set forth.
