Improved Method of and Apparatus for Effecting the Coiling up
and Drying of Textile Materials in the form of Slivers, Rovings,
or the like.
1, OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Fellow of the Institute of Patent Agents, do hereby declare
the nature of this invention to be as follows
-
This invention relates to an improved method and apparatns for facilitating the
coiling up and drying of all textile matters in the form of rovings, carded or
combed slivers, twists, etc., and in particular cotton rovings bleached or dyed before
the last operations of spinning.
The apparatus employed for this purpose include, firstly, a machine for effecting
the regular coiling up of the roving, and secondly a portable rack or frame on which
are placed the moveable spindles with their coils from the coiling machine, for
effecting the drying thereof.
The coiling machine is constructed as follows. A vertical framing carries the
trunnions of two long horizontal rollers of a square or polygonal cross section,
arranged one above the other, and above these are a series of reels or flanged
rollers strung side by side loose upon a horizontal spindle. The slivers or rovings
to be operated upon are passed up from receptacles at bottom past the said prismatic
rollers and separately over one of the reels. Rotary motion being imparted by
suitable gear, such as pullies and cords from a horizontal driving shaft, to the
prismatic rollers as the rovings pass in contact therewith, the rollers will have the
effect of straightening out any kinks or loops formed in the moist rovings as they
pass up to the reels above.
From the latter the rovings are led down to the coiling apparatus situated on
the opposite side of the framing.
This apparatus consists of a series of uprights, at the upper end of which are
heads, carrying firstly a vertical spindle on which is a bevil pinion with which
gears a bevil pinion on a horizontal shaft driven by suitable toothed gear from the
before mentioned driving shaft.
The vertical spindle also carries a spur pinion in gear with a spur wheel on
a hollow vertical spindle that passes down through the said head and fits on to a
tubular spindle fitting loose on a fixed solid spindle situated centrally within a
long cylindrical can for receiving the roving. The spur wheel on the hollow
spindle has an eccentrically placed tubular opening through it.
The sliver or roving is led from the before mentioned guide reel between a pair
of feed rollers on the head, which receive rotary motion from the before mentioned
driving gear, and which feed the roving forward to the tubular opening of the spur
wheel, so that on passing through such opening while the wheel revolves slowly,
the roving is laid in a coil in the can round the central spindle thereof.
The feed rollers have brushes or wipers on their outer sides which wipe off the
moisture left on them by the moist roving passing through, in order to prevent the
fibres from sticking to the roller's surface.
When the can thus becomes filled with the roving, the central tubular spindle,
which carries a disc at bottom, is drawn off the solid spindle together with the coil
of roving thereon and the spindle with the roving is then placed in the portable
rack to dry. This rack consists of a light open rectangular metal framing having
on opposite sides a series of horizontal bars arranged one above the other and
D

page_text: having a row of notches along their upper sides on which rest loose metal rods.
One of these rods is passed through one of the spindles with the coils of roving, and
the rod is then placed with its ends resting upon the notches of the said bars, so
that the coil of roving is supported quite free by the rods within the frame.
When the frame has been filled with coils of roving in this manner, it is raised
off the ground by means of handles, and is carried into the drying chamber.
Instead of employing the above portable racks or frames the spindles with their
coils may be placed upon horizontal travelling chains passing through a heated
drying flue so that the operation is rendered continuous, the coils of roving being
fed in wet at one end of the flue and removed in a dried condition at the other end.
The above described apparatus for coiling the slivers or rovings may also be
used for coiling these as they are delivered from the carding or roving machines,
before being bleached or dyed. For this purpose this apparatus is made to take
the place of the ordinary cans for receiving the slivers, and when these have been
coiled on the tubular spindles, these are removed from the cans, and a cord having
been passed through the spindle, the coil is slid off the latter on to the cord and in
this condition the coil is then dipped into the bleaching or dyeing bath.

Improved Method of and Apparatus for Effecting the Coiling up
and Drying of Textile Materials in the form of Slivers, Rovings,
or the like.
I, OLIVER IMRAY of No. 28 Southampton Buildings, Chancery Lane in the
County of London, Fellow of the Institute of Patent Agents 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 an improved method and apparatus for facilitating the
coiling up and drying of all textile matters in the form of carded or combed slivers,
rovings, twists, &c. and in particular cotton rovings bleached or dyed before the
last operations of spinning.
The apparatus employed for this purpose include firstly a machine for effecting
the regular coiling up of the roving, and secondly of a portable rack or frame on
which are placed moveable spindles with the coils from the coiling machine, for
effecting the drying thereof.
I will proceed to describe the construction of these several devices with
reference to the accompanying drawings in which
Fig. 1 shews a side view of the coiling machine.
Fig. 2 shews an end view.
Fig. 3 a sectional end view.
Fig. 4 a perspective view of one of the coiling devices with the hood turned up
on its hinge.
Fig. 5 shew a part sectional plan, and
Fig. 6 shews a perspective view of the rack or frame for receiving the spindles
with their coils.
The coiling machine consists of a vertical framing A one part of which carries
two rollers B B of rectangular or other prismatic cross section and, at top, small
bright iron rollers C C, while another part carries a shaft T which imparts rotary
motion to the rollers B by means of a pulley V and belt W and which has spur
wheels D which effect the rotation of the feed rollers E, the toothed disc F, and
the can P, by means of suitable intermediate gearing G H I, in the same manner as
with ordinary apparatus of this kind, and which need therefore not be further
described.

page_text: The hood X containing the feed rollers E, is shewn turned up on its hinge in
Fig. 4, in order to shew the brushes or small boxes filled with cotton waste J,
which constitute an essential feature of the invention and which are kept in contact
with the outer sides of the feed rollers, in order to remove therefrom any moisture
that may adhere to them from the wet sliver or roving K passing between
them, and thus prevent any adhesion of the roving to the rollers owing to the
moisture. In like manner the opening O in the disc F through which the roving
passes into the can P is- made sufficiently large to prevent any adhesion of
the moist roving to the sides thereof in passing through and thus causing an
obstruction.
Within the can P is a tubular spindle Q, Figs. 3 and 4 which slides loose upon
a solid spindle fixed at its lower end to the bottom of the can, the tubular spindle
having a disc R fixed to its lower end which rests upon the said bottom. The
upper end of the tubular spindle Q fits into a short tubular spindle S of larger
diameter which forms the axis of the wheel F and which can be readily withdrawn
when it is desired to remove the spindle Q when the roving has been coiled
thereon.
The apparatus consists secondly of a portable rack for receiving the spindles
charged with rovings as described, and for conveying them to the drying chamber
or stove. This portable rack is shown in perspective at Fig. 6.
It consists of an
iron framework M having at each end horizontal notohed bars N on which are
laid loose rods U. Handles Y are provided on the frame by which it can be
readily carried from place to place.
The mode of operating with the above described apparatus is as follows.
The rovings or slivers, after bleaching or dyeing, are first sorted in the ordinary
manner, and are then placed in recipients, such as boxes or cans, in front of the
coiling apparatus as shewn at Fig. 1. The one end of the roving is then passed up
against the rollers B and over the rollers C and is then led between the feed rollers E,
which are then set in motion, as are also the prismatic rollers B; these, in bearing
against the rovings as they pass up, have the effect of straightening out any
kinks K that may be formed therein, as indicated at Figs. 1 and 2, while the feed
rollers E deliver the smoothed rovings through the openings O into the cans P
where they are coiled up on the tubular spindles Q, as indicated at Fig. 3. When
the spindle has become filled by this means, the can is removed, for, which purpose
the short tubular spindle S is raised off the end of the spindle Q, and the can P
(which stops short at some distance below the bottom of the hood) can then be
drawn out. The spindle Q with its coil of roving is then readily drawn off the
rod of the can, the roving being kept on by the before mentioned disc at bottom,
and prevented thereby from becoming disarranged. One of the rods U of the
rack M is then placed at the end of the tubular spindle and the coil of roving is
slid from the latter on to the former which is then placed on the grooved bars N
as shewn, so that every part of the coil is freely exposed to the heat for drying.
When the rack has been filled by this means it is placed in the drying chamber or
stove.
Instead of employing the above portable racks or frames, or in combination
therewith, the spindles with their coils may be placed upon horizontal travelling
chains passing through a heated drying chamber or flue, so that the operation is
rendered continuous, the coils of roving being fed in wet at one end of the flue and
removed in a dried condition at the other end.
The above described apparatus for coiling the slivers or rovings may also be used
for coiling these as they are delivered from the carding or roving machines, before
being bleached or dyed. For this purpose this apparatus is made to take the place
of the ordinary cans for receiving the slivers and when these have been coiled on
the tubular spindles these are removed from the cans, and a cord having been
passed through the spindle, the coil is slid off the latter on to the cord, and in this
condition the coil is then dipped into the bleaching or dying bath.

page_text: 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:
1. The herein described method of coiling up and drying textile materials in the
form of slivers or rovings, in particular such as have been bleached or dyed before
the final stages of spinning wherein the said slivers or rovings, while still wet, are
first made to pass in contact with prismatic rollers that straighten out any kinks
therein and are then led between feeding rollers that deliver them into revolving
cans, and that are acted upon by brushes or equivalent appliances for removing the
moisture imparted thereto by the roving, this being caused to be coiled round a
central tubular spindle in the can in order to be conveyed into a suitable drying
apparatus, substantially as set forth.
2. The use, for carrying out the method of operating referred to in the
preceding claim, of a coiling apparatus consisting of the combination of revolving
prismatic rollers for straightening out kinks in the sliver or roving, feed rollers
for feeding the same forward and provided with brushes or boxes filled with
cotton waste for removing the moisture therefrom that adheres from the roving,
revolving cans with central spindles upon which are coiled the rovings, such spindles
having at their lower ends dises for facilitating the withdrawal of the coil from the
can, substantially as described.
3. The use in combination with the coiling apparatus referred to in the preceding
claims, of a portable rack having rods on which are strung the coils coming from
the coiling machine by means of which racks the coils are conveyed into a drying
apparatus substantially as herein described.
4. The use in lieu of or in combination with the racks referred to in the
preceding claim, of endless travelling chains situated in the drying apparatus
upon which chains are placed the said rods carrying the coils, substantially as
described.
