COMPLETE SPECIFICATION.
Improvements in Machines for Treating Yarns for Mercerising,
Dyeing, and the like.
We, JAMES ROLAND HOPE, Millwright, of 3321, Ridge Avenue, in the City and
County of Philadelphia, State of Pennsylvania, WILLIAM THOMAS GALEY, Manu-
facturer, of Overbrook, Philadelphia County, Pennsylvania, and THOMAS MCCONNELL,
Dyer, of 311, West Seventh Street, Chester, Delaware County, Pennsylvania, all
in the United States of America, 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:-
Our invention has reference to machines for treating yarns for mercerizing,
dyeing, etc., and consists of certain improvements which are fully set forth in the
following specification and are shown in the accompanying drawings.
In carrying out our invention we provide a main frame with one or more over-
hanging supports extending from one or both sides, and combine therewith a
power driven roller and one or more loose rollers arranged in connection with each
of the overhanging supports. These pairs of rollers are relatively adjustable to
or from each other and so sustained that they permit the yarn to be easily placed
upon them or taken off. The frame is preferably removable from a vat or tank
in which it sets, and is so proportioned that the lower roller alone may rotate in the
liquid contained therein. In the case of mercerizing, the caustic soda or other
alkaline solution is preferably only sufficient to submerge the lower rollers. In
our preferred form of apparatus the upper roller of a set is continuous so as to
overhang each side of the central frame and arranged to work in conjunction with
two loose, shorter, independent rollers at a lower level and respectively located
one on each side of the central frame so as to balance the weight of the rollers and
yarn upon the main frame to facilitate the handling thereof with its load when.
removed from the vat. We also prefer that there shall be a series of sets of these
rollers arranged parallel to each other, carried by the same main frame and adapted
to the same vat. We also prefer to drive all of the upper rollers by the same
power devices and to adjust the lower rollers simultaneously. It is of course
evident that the relation of the rollers may be inverted but we prefer the arrange-
ment specifically shown as being best suited to the purpose.
Our invention will be better understood by reference to the accompanying draw-
ings, in which :-
Fig. 1 is a transverse sectional elevation through our improved machine;
Fig. 2 is a plan view of one of the sections of yarn holding devices removed;
Fig. 3 is an end elevation of same;
Fig. 4 is a plan view of one end of the machine showing the relation of a series
of the sections shown in Fig. 2; and
Fig. 5 is a perspective view of one of the guides for the lower rollers.
A is a longitudinal main frame normally adapted to rest in the vat P¹ in a central
position as shown. Secured upon this frame are a series of sets of yarn carrying

page_text: A.s
rollers arranged parallel as shown. We will now describe one of these sets of
rollers and their connections and this may be taken as a description of them all.
B is a box frame and has extending laterally from it on opposite sides the arms C
terminating in heads D. E is a long roller approximately about 10 feet in length
and is carried in journal bearings e Fupon the frame B C D. This roller inter-
mediate of the bearings F has a worm wheel which is driven by a worm G on a
shaft g.
The arms C, C, are preferably formed of two parallel plates and of a
total width less than the diameter of the roller E as indicated by the dotted lines
in Fig. 2. H, H, are two short rollers or guides of about 4 feet long each and hung
below the arms: C and the outer portions of the rollers E.. These rollers H are
journalled in bearings I, I¹ vertically adjustable in any suitable manner.
shown, the bearing I is carried upon the bottom of a screw threaded shaft Ji
screwed into a nut L arranged in 'the head D and provided with one of a pair of
bevel gears M. The other of the gears is upon the end of the shaft K extending
through the center of the frame B, C, D, to the extreme opposite side. The other
bearing I is screwed upon a depending screw J, journalled in the frame B, and
geared to the shaft K by bevel gears k. When the shaft K rotates the bearings I, I¹
and their rollers H are elevated or depressed, and thus moved to or from the
roller E. The shaft K is rotated by worm and worm wheel gearing O and driven
by a transverse shaft P which may be turned by power or hand. When the machine
is operating for treating the yarn to the action of the liquor in the vat P¹ the
shaft P is stationary, and the shaft y continuously rotating. This rotation may
be always in the same direction or may be alternated in direction at intervals; as
is well known in this class of machinery. The bearing I is guided in the main
frame A, but as we prefer to have no fixed guides for the outer bearing I¹ on
account of the inconvenience therefrom of handling the yarn, we may arrange a
guide N upon a rock shaft n in the lower part of the vat or otherwise. This
guide N may be temporarily made to steady the outer bearing I¹ laterally when in
use. The shaft n carrying the guides N may be rocked by a suitable hand lever Q,
or the guides N be fixed in position in the vat.
•
The rollers H on both sides of the central frame A and their connections are
identical, hence the above description applies to all of said rollers. The vat P' may
be of any desired length and as many sets of rollers as preferred may be arranged
side by side and carried by the same main frame A, as is indicated in Fig. 4. The
shaft P operates all of the several shafts K simultaneously, and likewise the
shaft g operates all of the upper rollers E simultaneously and at the same speeds.
By the adjustment of the rollers E, H relatively to or from each other any
desired degree of tension may be put upon the yarn being treated.
When this machine is used for mercerizing, the frame A with its rollers is pre-
ferably lifted by a suitable crane or hoist (not shown) from or above the vat and
the yarn may be placed over the ends of the rollers. The lower rollers are then
adjusted to secure the proper tension and the apparatus lowered into the vat, or
the tension may be adjusted after the apparatus is lowered into the vat as desired.
It is evident that, if desired, the position of the adjusting roller may be reversed,
that is to say the adjustment may be applied to the upper rollers E in place of to
the lower rollers H as will be self evident to one skilled in the art. It is also to be
understood that rollers or portions thereof to one side of the frame A may be
omitted if desired. Therefore, while we prefer the construction as shown, the
minor details may be modified without departing from the spirit of our invention.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
First. The machine for treating yarns for mercerizing, dyeing, etc., constructed
and operating substantially as shown and described.
Second. The transverse overhanging frames carried by the main frame and sup-
porting the rollers.

page_text: Third. The adjustable bearings for the lower rollers combined
for adjusting said bearings.
WIUL
Fourth. The guides N for guiding the outer ends of the adjustable lower rollers.
