Hanks of Yarn.
I, GEORGE MAULE MARCHANT, of Chapel Hill Brass Works, Huddersfield,
in the County of York, Brass Founder and Finisher, do hereby declare the nature
of this invention to be as follows:-
This invention refers to machinery for scouring, dyeing or drying hanks of
yarn, and consists in the use of a suitably shaped vessel containing a series of
pairs of rollers for carrying the hanks.
I propose to give these rollers rotary motion for the purpose of changing their
position in the vessel so that the liquor or drying media can act upon every portion
of fibre. The method of giving rotary motion to these rollers (according to my
invention) is effected by frictional driving discs or wheels, or by endless belting,
or by endless chains; if the latter is employed, the wheels on the end of the hank
carrying rollers must be provided with pegs or studs. If the scouring or dyeing
vessel be circular, the hank carrying rollers, radiate from a central boss made to
revolve within the vessel; in this case the rollers are caused to revolve for the
purpose of changing the position of the hanks, by means of friction wheels fixed
on the rollers, such friction wheels riding over plates by which they are caused to
revolve.
The hanks are preferably placed over a scray or frame the bars of which can
be adjusted for the purpose of being adapted to hanks of different lengths, or for
the purpose of tightening or slackening the hanks. The scrays are removable
from the vessel and will be found of great advantage as they can be filled whilst
the machine is at work and made ready for putting into the vessel and when
removed from the vessel they can be taken to a suitable place to be dried. These
scrays can be used either in combination with rollers driven by friction, or by
toothed wheels or other means.

1, GEORGE MAULE MARCHANT, of Chapel Hill Brass Works, Huddersfield,
Yorkshire, Brass Founder and Finisher, 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 refers to machinery for scouring, dyeing or drying hanks of yarn,
and consists in the use of a suitably shaped vessel containing a series of pairs of
rollers for carrying the hanks and of means for imparting rotary motion to such
rollers.
In order more particularly to explain my invention, reference is herein had to
the accompanying drawings, wherein
Fig. 1 is a vertical section of machine for dyeing, scouring or drying hanks of
yarn constructed according to my invention;
Fig. 2 is a detail; and Fig. 3 shews a modified construction of machine and
methods of rotating the hank carrying rollers.

page_text: Referring to Fig. 1, A signifies the vessel to contain the dye or scouring liquor,
which is provided at B with steam pipe or pipes for heating the liquor. The
vessel as shewn is circular and if used for drying purposes it is closed in by any
suitable form of cover or lid.
Passing up through the centre of the vessel A is a hollow shaft C supported
in a footstep in the pedestal D and driven by bevils E from the shaft F which
forms the main driving shaft of the machine. The said hollow shaft C is
surrounded by a tube or sheath G bolted to the bottom of the vessel, which
prevents contact of the liquor with the shaft. C' is a square boss on the
hollow shaft C forming a bearing for the hollow tube or sleeve H which is
made square internally at the open end and fits onto and engages with the
square boss C' so that when the hollow shaft is rotated the tube or sleeve H. is
also carried around therewith. A flange a projects from the lower end of the
sleeve H and to this flange are bolted uprights b, c, to the lower ends of which
cross plates d are secured carrying at the opposite ends other uprights, c¹, forming
a framework for supporting the hank carrying rollers e, f; or said framework may
be made in one piece and bent to the shape required. The uprights b, b, c, c', are
slotted to allow for the adjustment of the bottom rollers to suit varying lengths
of hanks and said rollers are held in position either by the weight of the bearings g
or by securing said bearings to the uprights by set screws g' after the distance of
the rollers from the top rollers e has been adjusted. These bottom rollers are
easily removeable from their bearings, as are also the upper rollers e which, on
raising the inner ends clear of their bearings enables the rollers to be withdrawn
from the opposite bearings and when thus withdrawn the hanks can be removed
and fresh ones substituted, or said rollers can be inserted and withdrawn through
the friction disc on the frame which rotates said rollers. The journals of rollers e
are also adjustable slightly up or down to allow for wear and tear of the friction
discs or surfaces over which they ride and are secured, by set screws after adjust-
ment of the rollers. The frames supporting the bank carrying rollers radiate from
the centre of the machine as shewn and any number of said frames may be
provided and bolted to the flange a according to the capacity of the vessel
employed. When the several series of rollers are supplied with hanks rotary
motion is imparted to the hollow shaft C which rotates the sleeve or tube H, and
the frames being attached thereto are thereby carried around in a circle in the
machine. In order that rotary motion may also be given to the upper hank
carrying rollers for the purpose of changing the position of the hanks thereon and
expose every portion of the yarn to the action of the liquor, one end of each of
said rollers engages with or has mounted thereon a friction disc which rides
over the surface of an internal flange or rib on the sides of the vessel and by
frictional adhesion therewith causes said pulley and its hank carrying roller to be
rotated.
After the operation of dyeing, scouring, or drying has been completed, the
frames with their rollers carrying the hanks are raised out of the vessel A for
removal of the banks, and this is effected by means of a screw K and nut l, the
latter being adapted to slide up and down in the hollow shaft C but is prevented
from rotating with the screw by a stud or projection m entering a slot or groove m¹
in the hollow shaft. The said nut engages the upper end of the hollow sleeve H
and on the machine being stopped the bevil wheel I on the counter shaft J is
slided by means of lever n and rod o into gear with the bevil wheel K¹ on the
screw shaft K which passes up through the centre of the hollow shaft C and is
supported in a footstep in the pedestal D.
The screw shaft K is by this means rotated and the screw K causes the nut / to
rise and thereby lift the sleeve H and the frames and hanks out of the vessel as
indicated by dotted lines. The bevil wheel I is held in gear whilst the frames are
being raised out of the vessel by a spiral spring p. The rollers e, f, instead of
having to be inserted into the frames separately may be journalled in a frame or
scray r as shewn at Fig. 2. The uprights b, b, c, c', are provided with side flanges

page_text: or a projecting beading to receive and hold the scrays in position. This arrange-
ment enables the frames or scrays with their complement of hanks to be removed
bodily from the frames in the vessel and taken to another machine, and it also
permits of the scrays being filled with hanks whilst the machine is working in
readiness to take the place of those removed.
น
The hanks may be slackened from time to time by inclined surfaces t on the floor
of the vessel which are engaged by friction pulleys on the end of spindles
abutting against the journals g, and forcing them up in the slots in the frames
against their own weight alone or against the pressure of spiral springs.
At Fig. 3 I shew a modified construction of machine wherein the hank carrying
rollers are rotated by frictional driving discs in engagement with each other.
The upper hank carrying rollers at one end fit into square openings or recesses
formed in the friction discs and are journalled in the frames or scrays r which are
held in position in the vessel by guide plates s each frame with its hank carrying
rollers being complete in itself and adapted to be removed or inserted bodily into
the machine when filled with hanks of yarn; but if required fixed frames may be
employed instead of the removeable scrays r. The motion for driving the hank
carrying rollers is obtained from the shaft K and communicated by the disc or
pulley L mounted thereon to the friction disc on the end of the first roller which
by rolling contact is transmitted to the several discs and the hank carrying rollers
thereby rotated and the position of the hanks thereon changed so as to expose
every portion of the yarn to the liquor. Instead, however, of driving by frictional
contact as described, smaller wheels or pulleys may be mounted in the machine in
lieu of the friction discs, and rotary motion given thereto by an endless belt or
chain as indicated in dotted lines, the said wheels, if a chain is employed, being
provided with studs or pegs.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In hank dyeing scouring or drying machines, the employment of friction
discs, endless belts or chains for imparting rotary motion to the hank carrying
rollers.
Secondly. The combination, with a machine for dyeing scouring or drying banks,
substantially as herein set forth, of scrays or frames provided with hank carrying
rollers adapted to be driven by frictional driving discs or by endless belts or chains,
the bottom rollers being adjustable up or down to adapt the scrays or frames to
hanks of different lengths.
Thirdly. In hank dyeing scouring or drying machines, the means substantially as
herein shewn and described for raising the frame with their hank carrying rollers
out of the vessel.
Fourthly. The general arrangement, construction and combination of machine
for dyeing scouring and drying hauks of yarn, substantially as shewn at Figs. 1
and 2 and as herein described with reference thereto.
