Improvements in Warp or Yarn Washing and Scouring, Sizing,
Dyeing, Drying, and Polishing Machines.
1, JOHN TATTERSALL, of the Globe Works and Stores, Enschede, Manu-
facturer, 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 :-
The upper or top roller of warp or yarn washing and scouring, sizing, dyeing,
drying and polishing machines have never before been provided with a separate
driving mechanism, and it has received rotary motion only through the movement
of the lower roller or cylinder.
It is obvious that in such case the upper roller, which actually rests on the warp
or yarn, is caused to rotate by the moving warp or yarn, and is therefore liable to
slip and, as a consequence thereof, the uppermost layer of warp or yarn may
become strained, stretched and damaged.
In order to obviate this disadvantage it is herein proposed to provide a separate
driving gear for the upper or top roller, the adoption of which enables the rollers
to be weighted more heavily than has been possible heretofore, so that by this
means the liquid for treating the warp or yarn is enabled to enter and to leave the
warp or yarn more evenly than before, while at the same time the warp or yarn
receives the same pressure throughout and leaves the machine in a uniformly
stretched condition.
In the accompanying drawings
Fig. 1 represents a front elevation of the machine with parts removed.
Fig. 2, a side elevation of the same with parts removed and partly in section,
and
Fig. 3, a detail view on an enlarged scale of a part of the driving mechanism.
The upper roller b and the lower roller or cylinder c are supported at both their
ends in the frame a. The roller b is weighted so as to press down on the roller c,
which latter receives movement from the shaft d through the medium of toothed
wheels d¹ c¹.
m
b is driven from the shaft e in the following manner. A disc g, covered at f with
cloth or flannel, is made in one with a long sleeve rigidly keyed to the shaft e.
On said sleeve h is loosely mounted a toothed pinion provided with a flange at
each side and gearing into a toothed wheel c² on the shaft c. A disc i, also covered
at k with cloth or flannel, is mounted on the sleeve h in such a manner as to enable
it to be moved in a longitudinal direction on the latter by means of a lever l. It is
obvious therefore that by pressing the lever 1, either in the one or other direction,
the pinion m will be gripped between the discs g and i, and thereby cause the
shaft e to rotate, or it will run loose on the sleeve and allow the shaft e to come
to rest.
Rotary motion is communicated from e to 6 by auy suitable means, such as belt,
chain or rope and the like.
In the present example the former is preferred as a driving medium, and for this
purpose the pulleys n and o with belts have been provided.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what. I
claim is :-
1. In warp or yarn washing and scouring, sizing, dyeing, drying and polishing
machines, the driving mechanism for driving the upper or top roller and consisting

page_text: of an intermediate shaft on which is keyed a cloth or flannel covered disc provided
with a long sleeve, which latter carries a loose toothed pinion driven from the lower
shaft and a loose disc covered with cloth or flannel arranged in such a manner that
when the latter disc is pressed, by means of a lever, against the said pinion so as to
press the latter against the fixed disc, the intermediate shaft is caused to rotate and
to communicate its rotary movement, through the medium of belts, chains, ropes
or the like, to the upper or top roller, substantially as herein shown and described.
2. The improvements in warp or yarn washing and scouring, sizing, dyeing,
drying and polishing machines, substantially as herein shown and described and for
the purpose stated.
