PETER THOMAS and JACQUES ZIVEIFEL. both of Manchester in the County of
Lancaster "IMPROVEMENTS IN MACHINERY AND ARRANGEMENTS FOR BLEACHING,
DYEING SIZING, OR WASHING HANKS OF YARN
"
The Invenion relates more particularly to that class of machinery where yarns of
cotton, linen, jute or other fibres are bleached, dyed, sized or washed, in the hank
and is specially applicable to a method of bleaching for which letters patent were
granted to Peter Thomas N° 549 A.D. 1882.
The object of our invention is to bleach, dye, size or wash a suitable large
quantity of hanks of cotton linen, jute or other fibres in considerable less time than
is required by the use of any other machinery or apparatus known, for the same
purpose heretofore, and whereby the work is also performed more satisfactory, as
regards quality and the cost thereof is considerably reduced. To this end we
arrange a suitable number of vats, say for example, three, all placed in a row and
each one containing a different dip.
Removable cross-bars of which two by two are arranged to take up a number of
hanks, are carried on each end respectively by two longtitudinal bars. The latter
are suspended from two shafts forming a part of a framing by means of levers
working on eccentrics and fixed on the said shafts. The eccentric motion
imparting a reciprocating motion to the longtitudinal bars causes the cross-bars to
change their respective positions continually from a higher lever to a lower level.
By these means we are enabled. to permit the liquid to impregnate the hanks in a
more complete manner which acts beneficial to the same and a better result is
thereby obtained. In some cases where it is necessary to bring that part of the
hank, which is nearest to the bottom of the vat, on the top of the cross-bars; we
impart to the longtitudinal bars respectively a motion which will cause the cross
bars alternately to make a part of a revolution and return to its original position. in
order to move the hanks as set forth. The said framing is carried by a carriage,
which latter is caused by means of ropes and chains and a reversing gear situated
at the end of the row of vats to travel from end to end of the vats, and may be
stopped at any convenient point. On the top of the said carriage two shafts
provided with pullies are arranged over which are placed ropes or chains, one end

page_text: thereof being connected to the framing inside the carriage, and the other end to a
balance-weight which runs outside the carriage for the purpose of lowering and
lifting the said frame in and out of the vats. Motion is imparted to the said
shafts by means of straps and pullies from a reversing gear carried on a shaft by
a bracket fastened to the side of the carriage.
The
The motion for the eccentric shafts is obtained from the same shaft on which the
said reversing gear is placed by means of pullies and ropes, chains or straps and
can be engaged or disengaged as required by the aid of a coupling and lever.
said bracket carries also at its lower end a pulley provided with one-half a
coupling; a corrresponding half, forming also a spiral cord-pulley or chain-pulley
fixed to each vat and when engaged by means of a lever will cause to revolve the
said pulley and transmit motion by straps to pullies carried by the shaft on the top
of the said bracket or stop all the motions carried by the carriage when disengaged.
The spiral cord pullies or chain pullies are driven by means of ropes or chains
from pullies revolving on the same shaft as the reversing gear which causes the
carriage to travel from end to end of the row of vats and can be stopped or
brought into motion as required. The operation of the machine is as follows.
After the hanks are placed onto the cross-bars, the frame inside the carriage is
lifted by means of the reversing gear and the carriage caused to run to the
required vat, where, when in position, the frame will be lowered and the hanks
immersed in the liquid. The eccentric motion is then brought into operation and
will cause the bars to move as described. After the hanks have been in the liquid
a certain time the frame is lifted again and the carriage is run to another vat
where the same operation will be repeated until the process is completed.
