We, CHARLES MATHER and JAMES ORMESHER, trading as Mather, Ormesher &
Co., of Bridge Mill; Middleton; near Manchester; in the County of Lancaster,
Dyers and Finishers of Yarns, do hereby declare the nature of this invention
to be as follows:-
Our said invention has reference to improvements in or connected with pre-
paring machines, used for preparing and finishing cotton and similar yarn in the
hank, as is well understood by those connected with the textile industries.
In a class of machine now employed for this purpose, three bowls are suitably.
mounted one above another and act on the yarn, the top bowl being positively
driven whilst the lower bowls are frictionally operated therefrom.
The bank is supported, endless belt fashion, by passing partly around a carrier
bobbin or pulley carried on a spindle, and thence partly around the central bowl
so that the yarn is acted upon at two points. The central bowl is journalled in
parts which permit it to swivel or move from contact with the top and bottom
bowls when doffing.
Under this arrangement owing to the excessive nip necessitated by the top
bowl having to communicate motion to the two lower bowls, the yarn is apt fo
be cut or broken, and at all events receives harsher treatment between the upper.
and middle than between the middle and lower bowls. To remedy this defect.
is the object of our invention and to this end we positively drive the central
bowl.
The means by which we at present effect the driving of such central bowl are
as follows. At the back of machine and say behind the central bowl we provide
a suitable shaft running in bearings and carrying a fast and loose pulley for
driving purposes. This shaft also carries a spur pinion, which meshes with
another pinion fixed on the shaft or axle of the central bowl, so that on the fast
pulley being driven, motion is imparted to the central bowl which in turn fric-
tionally operates the upper and lower bowls.
We still mount the central bowl in bearings which permit it to swivel for
doffing purposes, the swivelling of the bowl of course removing the pinions out
of gear, the pinions again engaging after the insertion of a fresh hank and the
moving in of the bowl.
We may provide means to prevent the moving into gear of the pinions until
such time as the attendant operates a suitable part.

page_text: Instead of the spur pinions fixed on the two shafts, we might employ two
friction discs or the like, capable of engaging and disengaging each other.
It will be obvious that motion might be imparted to the central bowl by
means other than those above indicated and it must be understood that we do
not confine ourselves in this respect.
By driving the central bowl, the bowls are not nearly so severe on the yarn
nor is the same likely to be cut or broken, whilst the hank is much more uni-
formly treated.
Improvements in or connected with " Preparing Machines" for
Preparing and Finishing Yarn in the Hank.
We, CHARLES MATHER and JAMES ORMESHER, trading as Mather, Ormesher &
Co., of Bridge Mill, Middleton, near Manchester, in the County of Lancaster,
Dyers and Finishers of Yarns, 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 and accompanying drawings:
Our said invention has reference to improvements in or connected with pre-
paring machines used for prepaving calendering and finishing cotton and
similar yarn in the hank as is well understood by those connected with the
textile industries.
In a class of machine now employed for this purpose three bowls are suitably
mounted one above another and act on the yarn the top bowl being positively
driven whilst the lower bowls are frictionally operated therefrom.
The hank is supported endless belt fashion, by passing partly around a carrier
bobbin or pulley carried on a spindle and thence partly around the central bowl
So that the yarn is acted upon at two points. The central bowl is journalled in
parts which permit it to swivel or move from contact with the top and bottom
bowls when doffing.
Under this arrangement owing to the excessive nip necessitated by the top
bowl having to communicate motion to the two lower bowls, the yarn is apt to
be cut or broken, and at all events receives harsher treatment between the upper
and middle than between the middle and lower bowls.
To remedy this defect is the object of our invention and to this end we posi-
tively drive the central bowl.
The arrangement of parts we have found most suitable for carrying our inven-
tion into effect will be clearly understood from the following description in
which reference is made to the annexed sheet of drawings.
In the said drawings,
Fig. 1 is a side elevation of so much of a preparing machine as is necessary
to show the application of our invention thereto,

page_text: Fig. 2 is a front elevation of Fig. 1.
Fig. 3 is a detail view.
The three calendering bowls in the accompanying drawings are marked a, b, c.
According to our invention we effect the driving of the central bowl 6 as
follows. At the back of the machine and say immediately behind the central
bowl we mount a suitable shaft d this shaft being free to revolve in bearings
carried. by the end standards A such brackets however not being shown in the
drawings. The shaft d carries fast and loose pullies e, f, motion being imparted
to the fast pulley e by means of a belt g whereby the shaft d may be readily
rotated. Upon the shaft is keyed or otherwise secured a spur pinion h which
gears or meshes with another pinion i fixed on the shaft or axle 61 of the central
bowl b, so that on the fast pulley being driven motion is imparted to the central
bowl b which in turn frictionally operates the upper and lower bowls & c.
The central bowl is carried in bearings j mounted to swivel in brackets j¹ for
doffing purposes as is usual, this mounting and swivelling of the central bowl
forming no novel part of our invention.
The swivelling of the central bowl removes the pinion out of gear with the
pinion the pinions again engaging after the insertion of fresh hanks and the
moving in again of the bowl.
In order to prevent stripping of the pinion teeth on the moving in of the
central bowl b we prefer to throw the driving strap g on to the loose pulley f
so that the pinions engage whilst at rest whereupon the strap g may be again
shifted to the fast pulley e. The strap shifting arrangement employed for this
purpose is clearly shown in the drawings and consists of a sliding belt fork k
carried on a bar 7. The belt fork & is slid along the bar 7 by means of a handle_m
carried on a spindle m¹ connected to the belt fork k by means of links n n'. By
operating the handle m the belt g is readily shifted from the fast to the loose
pulley or vice versa.
When treating yarn on a preparing machine constructed in accordance with
our invention the hanks are arranged around the swivelled central bowl 6 and
the usual carrier bobbin (not shown in the drawings) the strap y meanwhile
running on the loose pulley f so that the shaft & remains at rest. The hanks
having been arranged the central bowl b is now moved into position by means
of the handle o between the upper and lower bowls so that the pinions i, h, gear
with one another the central bowl being maintained in this position by a catch
as is usual.
Having moved in the bowl, the attendant allows the lower bowl c which has
been previously lowered to rise, and shifts the strap g to the fast pulley e, by
operating the handle m, so that the pinion h at once commences to revolve
actuating in turn the pinion i land consequently the central bowl the upper
and lower bowls a deriving their motion from frictional contact with such
central bowl.
When the yarn has been acted upon a suitable length of time
the catch retaining the central bowl in working position is automatically released,
the central bowl swivelled and the lower bowl e lowered in the ordinary and
well known manner.
The swivelling of the bowl b removes the pinion i from gear with the pinion h
as before stated whereupon the strap g may be shifted to the loose pulley f and
the hanks duly doffed.
In order to dispense with the necessity for shifting the belt when dealing
with each set of hanks, we might in lieu of the spur pinion h, i, employ friction
discs or the like capable of engaging and disengaging each other at the required
time.
By driving the central bowl the howls are not nearly so severe on the varn
nor is the same likely to be cut or broken. Moreover under our invention the
yarn is much more uniformly treated so that not only is less waste produced than
heretofore but a superior finish is imparted to the yarn.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed' we' declare that what
we claim is:-
In preparing machines of the indicated nature for polishing, calendering, and
finishing yarn in the hank actuating the central bowl in the first instance in 5
the manner for the purposes and substantially as hereinbefore described and
shown.
