COMPLETE SPECIFICATION filed by the said William Robert Lake at the
Office of the Commissioners of Patents on the 1st November 1883.
WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake and Co, Patent Agents,
Southampton Buildings, London "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR USE IN DYEING OR CLEANING YARN communicated to me from Abroad by
John H. Lorimer of Philadelphia, Pennsylvania, United States of America, Dyer
This invention relates to machines for dyeing or cleansing yarns; and comprises
various improvements as hereinafter set forth.
In the accompanying drawing.
Figure 1 is a sido elevation of a dyeing machine constructed according to this
invention.
Figure 2 is an elevation of the opposite side of the same
Figure 3 is a longitudinal section."
Figure 4 is a plan view of a portion of the endless belts.
Figure 5 is a transverse section of the same and
Figure 6 is a sectional elevation showing a modified arrangement of the feed and
squeezing rolls.
A indicates the tank which may be made of metal. The said tank carries within
it a series of rollers B, C, C, C³, C, C and D, of which B is a drive roller,
C, C, C, C, and C' guide rollers, and D, D idler or supporting rollers.
F F indicate two endless aprons made of iron slats f¹ hinged at each end to the
links of two endless chains f. The apron F passes around the roller C under the
rollers C, C and around the feed roller E located above the tank. A. The

page_text: •
apron F¹ passes over the drive roller B, running upon the rollers D; it then passes
around the roller C¹ in contact with the apron F, the rollers C and C², and feed
roller E, below the roller E¹. It then leaves the apron F passing down around the
roller C³, under the rollers D, around the rollers C, and back to the roller B. From
this it will be seen that the heavy aprons are in contact from the roller C¹ to the
rollers E E, and during their passage from the roller C₁ to roller C³ they are under
the dyeing or cleaning liquid.
If the aprons sag they may rest loosely upon the rollers D close to the bottom of
the tank A.
The arrows, Figure 3, indicate the line of travel of the aprons.
The rollers E E¹ can be adjusted towards or from each other by adjustablo
boxes e which carry the roller E'.
H, H¹ indicate the squeezing or wringing rolls; one of the said rollers may be
covered with india-rubber h while the other is of metal. These rollers are geared
together by gear wheels H and are pressed together by a weight and a series of
levers and rods K K K which press down on sliding bearings J carrying the
upper roller H.
These rollers and power mechanism are located in a frame G which is bolted to
the end of the tank A. Under the rollers H H¹ a pan W may be secured to cause
the expressed liquid to run back into the tank. In practice it is desirable that the
feed rollers E E be so arranged with respect to the rollers H H' that their line of con-
tact will come substantially on a line with the axle of the lower roll H as shown in
Figure 6, for then, as the yarns are fed to the wringing rolls they will be carried up
between the said rolls, and will have no tendency to fall down between the rolls E
and H and be carried back to the tank by the apron F¹.
Mindicates the driving or band wheel, and L its shaft. A pinion P is secured
upon the shaft L and engages with the spur wheel Q on the shaft of the lower
wringing roller, H, and by which the rolls H H' obtain their power.
Also secured
to the shaft L is a sprocket wheel N over which a chain n passes to drive the
wheel N¹, and this in turn drives the sprocket wheels O, from which chains o and e¹
pass to the wheel O¹ on roller B and the wheel E on the feed roller E, and which
latter in turn is geared with the roller E' by spur wheels E. By this means the
wringing rolls and endless aprons are rotated or made to travel with uniform
velocity.
Steam may be admitted to the liquor in the tank through a pipe R and
branches R¹, and controlled by a valve r.
The liquor may be run 'off' from the tank A by a valve S which may be actuated
by rod S¹, lever S3, and hand lever S³, and the latter may be secured tightly to a
segmental arın T by a screw t to keep the valve up or down.
The operation of the machine is as follows, that is to say. the yarns aro laid
upon the apron F¹ as it passes over the roller B, and are then carried down
between the aprons F' and F, passing below the liquid dye, and finally upwards;
being discharged by the feed-rollers E E' to the squeezing or wringing rollers H H¹
which extract the excess of liquid dye, the latter running back into the tank by
the pan W; the pressure between the aprons being irregular the slight compression
and expansion necessary to the yarn to make it absorb the dye are given and the
use of compressing and expanding rollers under the liquid becomes unnecessary.
Having thus fully described the said invention as communicated to me by my
Foreign Correspondent, and the manner of performing the same, I wish it
understood that I Claim.
First. The combination of the wringing rollers with two endless feed aprons,
a tank, and feed-rollers, the latter being so arranged (with relation to the wringing
rollers) that their line of contact is considerably below the line of contact between
the said wringing rollers.
Second. The combination of a dye tank with two endless aprons made of
inetal bars hinged at each end to endless chains, substantially as shown and
described.

page_text: Third. The combination of the wringing rollers, feed rollers, a dye tank, and two
endless aprons composed of metal bars hinged to endless chains, as set forth.
Fourth. A dye-tank in combination with two endless metallic aprons and guide
rolls, so arranged that the said aprons are separated to receive and discharge the
yarns, but are pressed together by their own weight when carrying the yarn below
the level of the liquid, as set forth.
Fifth. The combination of the tank A, the rollers B, C, C1, C2, C3, C4, and D, the
feed rolls E, E¹, the endless aprons F, F', and the wringing or squeezing rollers, all
constructed substantially as set forth.
Sixth. The combination of the two squeezing or wringing rollers with the two
endless aprons, a tank, feed rollers and means for adjusting the said feed rollers
and wringing rollers.
Seventh. The combination of squeezing or wringing and feed rollers, two endless
aprons and a tank, with the band wheel M, the shaft L, the sprocket-wheel N, the
chain n, the wheels N¹, O, the chains o and e', the wheel U¹ and the wheel E³,
substantially as set forth.
In Witness whereof I the said William Robert Lake have hereunto set my hand
and seal this First day of November in the year of our Lord one thousand eight
hundred and eighty three.
