Improvements in and relating to Sizing or Slashing Machines.
I, HENRY MARTIN, of 63, Queensberry Road, Burnley, in the County of
Lancaster, Taper, do hereby declare the nature of this invention to be as
follows:-
This invention relates to sizing or slashing machines employed in sizing
dhooties or other yarns, in which stripes of grey yarn are intermixed with
coloured yarn. Hitherto, the coloured yarn has been run over the drying
with
cylinder of the sizing or slashing machine on the top of the grey yarn,
the result that it has either not been properly dried, owing to the presence of
the grey yarn betwixt it and the surface of the drying cylinder, or otherwise
the grey yarn is liable to be seared, browned, burnt or discoloured owing to the
excessive heating of the drying cylinder to effect the drying of both the
grey and coloured yarns simultaneously.
My invention has the object of remedying this evil by the employment of a
auxiliary drying cylinder in addition to the large and small ones now employed
in slashers. I am aware that auxiliary drying cylinders have been previously
employed in sizing or slashing machines for more expeditiously effecting the
drying of the ordinary cotton yarns, but according to my invention, by suitable
means I divide the course of the grey and coloured yarns respectively in their
passage through the machine after passing over the usual drying cylinders, and
then carry the coloured yarn over the auxiliary drying cylinder before men-
tioned, so that the drying of the coloured yarn will be properly effected, with-
out injuring in the slightest degree the grey yarn.
are carried over
For this purpose, both the grey yarn and coloured yarn
the large drying cylinder of the slasher, then round the small cylinder as in the
usual manner.
Both yarns
now pass round a small roller mounted in the
frame of the machine, and brought forward to another roller, where they then
separate, and the grey yarn passes forward through the machine, whilst the
coloured yarn only is passed over my improved additional or auxiliary drying
cylinder, a small leasing rod or roller being interposed at the point of divergence
of the two yarns to facilitate their separation.
After traversing the auxiliary drying cylinder the coloured yarn is returned
to a suitable position near the grey yarn, and carried round a small roller, both
yarns now taking their usual course through the machine. By this means,
the coloured yarn may be properly dried without the means employed in any
way injuring the grey yarn.
The auxiliary drying cylinder for drying the coloured yarn may be mounted
in suitable standards, and may be driven by a vertical and horizontal shaft and
toothed gear from the side shaft of the sizer or slasher, or it may be placed

frictional contact of the warp threads alone, but we prefer the former method.

Improvements in and relating to Sizing or Slashing Machines.
I, HENRY MARTIN, of 63, Queensberry Road, Burnley, in the County of
Lancaster, Taper, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
This invention relates to sizing or slashing machines employed in sizing
dhooties or other yarns, in which stripes of grey yarn are intermixed with
coloured yarn. Hitherto, the coloured yarn has been run over the drying
cylinder of the sizing or slashing machine on the top of the grey yarn, with
the result that it has either not been properly dried, owing to the presence of
the grey yarn betwixt it and the surface of the drying cylinder, or otherwise
the grey yarn is liable to be seared, browned, burnt or discoloured owing to the
excessive heating of the drying cylinder to effect the drying of both the
grey and coloured yarns simultaneously.
My invention has the object of remedying this evil by the employment of an
auxiliary drying cylinder in addition to the large and small ones now employed
in slashers. I am aware that auxiliary drying cylinders have been previously
employed in sizing or slashing machines for more expeditiously effecting the
drying of the ordinary cotton yarns, but according to my invention, by suitable
means I divide the course of the grey and coloured yarns respectively in their
passage through the machine after passing over the usual drying cylinders, and
then carry the coloured yarn over the auxiliary drying cylinder before men-
tioned, so that the drying of the coloured yarn will be properly effected, with-
out injuring in the slightest degree the grey yarn.
For this purpose, both the grey yarn and coloured yarn are carried over
the large drying cylinder of the slasher, and then round the small cylinder as in
the usual manner. Both yarns now pass round a small roller mounted in the
frame of the machine, and are brought forward to another roller where they then
separate, and the grey yarn passes forward through the machine, whilst the
coloured yarn only is passed over my improved additional or auxiliary drying
cylinder, a small leasing rod or roller being interposed at the point of divergence
of the two yarns to facilitate their separation.
After traversing the auxiliary drying cylinder, the coloured yarn is returned
to a suitable position near the grey yarn, and carried round a small roller, botli
yarns now taking their usual course through the machine. By this means
the coloured yarn may be properly dried without the means employed in any
way injuring the grey yarn.
The auxiliary drying cylinder for drying the coloured yarn may be mounted
in suitable standards, and may be driven by a vertical and horizontal shaft and
toothed gearing from the side shaft of the slasher or sizer, or it may be placed
behind instead of in front of the drying cylinder, and may then be driven by
frictional contact of the warp threads alone, but I prefer the former method.

a like
A is the large drying cylinder of sizing machine, B the side shaft, with which
gears by bevel gear the vertical shaft C, which transmits motion in
manner to the horizontal shaft D, by means of which my improved auxiliary
drying cylinder E for drying the separated coloured yarn is driven.
Both the grey yarn and the coloured yarn G are passed over the large
drying cylinder A in the usual manner. They may then traverse together the
usual small drying cylinder not shewn on the drawing.
After passing round the small drying cylinder, both the grey and coloured
yarns are brought forward over the roller J to the roller K, where they diverge,
the coloured yarn G being passed over my improved auxiliary drying cylinder E,
then round the roller M, and forward through the machine.
The small leasing
rod or roller N may be placed at the point of divergence of the two yarns to
assist in their separation.
The grey yarn F, after passing the roller K, re-unites beyond the roller M
with the coloured yarn G now thoroughly dried, and both yarns now run for-
ward to the front or headstock of the machine.
It will be readily seen that my invention as described effectually dries the
coloured yarn in sizing dhooties and other mixed yarns, without damaging or
browning the grey yarn.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
1. In a machine for sizing dhooties and similar goods, the separation of the
coloured and grey yarns respectively, and the passing of the coloured yarn only
over an auxiliary drying cylinder, substantially as and for the purpose
described and illustrated.
2. In a machine for sizing dhooties and similar yarns, the combination of the
rollers J and K, leasing rod N, roller M, and auxiliary drying cylinder E, for
effecting the separation and drying of the coloured yarn, and the ultimate
re-union of both coloured and grey yarns, substantially as described and
illustrated.
