Improvements in Apparatus for Dyeing, Bleaching, or otherwise
Treating with Liquids Cops of Yarn.
JAMES MAJOR, of 28, Cannon Street, Mechanical Engineer, and THOMAS JAMES
Wood, of 30, Cannon Street, Manufacturer, both of Eccles, in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements upon the apparatus for which a
application for Letters Patent No. 25525 of 1898 was filed by us on the 3rd of
Decr., the object of the present invention being to facilitate the process
and to improve the construction and arrangement of the apparatus employed.
According to our present invention we arrange in juxta-position any con-
venient number of open vats or cisterns, above which we erect a framing pro-
vided with rails upon which slides or otherwise moves a carriage provided
with depending guide rods upon which a frame carrying a group of spindles
with their cop carriers and means for revolving the same, can be raised or
lowered into or out of the liquor contained in the vats, each frame being sus-
pended by cords or chains passing over pulleys and counterbalanced by suitable
weights.
The carriage is moved along the rails by hand as required by means of an
endless rope passing around pulleys at each end of the rails.
The spindles are solid and are provided near the top with inverted cups
running on ball bearings: At the lower end of each spindle is attached a centri-
petal fan or pump with curved blades which, as the spindle revolves in the
liquor, draw the latter inwards towards the centre and force it downwards into
a tubular perforated or other open form of cop-carrier attached to the lower
part of the fan or pump, and as the spindle with its centripetal fan or pump
revolves rapidly the liquor is forced by the fan or pump into the interior of the
cop and is thrown outwards through the same by the centrifugal force created
by its rapid revolution.
The means for revolving the spindles in this improved apparatus is as
follows: Each spindle is provided near its upper end with a wharve constructed
in two discs, one of which is fixed by a long boss on the spindle and the other
or opposing half is capable of sliding up and down thereon. The opposing
faces of each disc are bevilled inwards so that the two together form a V-grooved
pulley, the moveable disc being pressed against the fast one by a spiral or other
spring or equivalent which gives a certain amount of elasticity thereto sufficient
to cause the two bevilled surfaces to grip the strap or belt which is of a rect-
angular form in section and set cornerwise. The spindles are preferably arranged
in groups of say 48 or other preferred number in four parallel lines of 12 spindles
each and are placed so closely together that one short endless strap or belt pass-
ing between the first and second rows, then round a grooved carrier pulley and
returning between the third and fourth rows and round a similar pulley at the
opposite end and back again will drive the whole group.
Each cop carrier is preferably made of (say) three wires fixed in a ferrule at

page_text: one end and bellied out slightly in the centre to give a better hold on the inside
of the cop and all united together so as to form a point at the other end.
To fix the open ends of these wires in the ferrule we employ a short boss or
plug made with three longitudinal grooves on the outside to receive the wires
and keep their ends apart, and the wires are laid in these grooves and inserted
in the lower end of the ferrule and fixed by soldering or otherwise. The upper
end of the ferrule is made slightly conical and the lower end of the fan casing
similarly conical, so that the cop carriers can be fixed by simply jamming them
fast into the conical hole in the lower end of the fan casing, and removed there-
from by means of a small instrument in the shape of a lever inserted between
the latter and a flange with which the lower end of the ferrule is provided for
that purpose.
The spindle above the fan is enclosed in a fixed tube the lower end of which
carries a ring provided with fixed vanes on the inside the lower edge of this rim
nearly touching the upper edge of the revolving centripetal fan or pump so as
to prevent the "swirling" of the liquor which would otherwise take place. The
upper end of this fixed tube extends through the ball bearing and inside the
inverted cup (before named) which is fixed on the spindle so that there is no
possibility of oil from the said bearing running down the spindle and so injuring
the cops. The extreme upper end of the spindle is provided with a cupped stop or
bearing running on a diamond point at the bottom of an adjusting screw.

Improvements in Apparatus for Dyeing, Bleaching, or otherwise
Treating with Liquids Cops of Yarn.
We, JAMES MAJOR, of 28, Cannon Street, Mechanical Engineer, and THOMAS
JAMES WOOD, of 30, Cannon Street, Manufacturer, both of Eccles, in the County
of Lancaster, 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:-
This invention relates to improvements upon the apparatus for which Letters
Patent No. 25,525 dated December 3rd, 1898 were granted to us, the object of
the present invention being to facilitate the process, and to improve the construc-
tion and arrangement of the apparatus employed.

According to our present invention we arrange in juxtaposition any convenient
number of open vats or cisterns a, above which we erect a framing h, provided
with rails c, upon which slides or otherwise moves a carriage d, provided with
depending guide-rods c, upon which a frame f. carrying a group of spindles g,
with their cop-carriers h, and means for revolving the same, can be raised or
lowered into or out of the liquor contained in the vats a, each frame f being
suspended by cords or chains i, passing over pulleys and counterbalanced by

is
The spindles are solid and are provided near the top with inverted cups,
running on ball-bearings Fig. 6. At the lower end of each spindle
attached a centripetal fan or pump y, with curved blades, which as the spindle y
revolves in the liquor draw the latter inward toward the centre and force it
downward into a tubular perforated or other open form of cop-carrier h, attached
to the lower part of the fan or pump q and as the spindle g, with its centripetal
fan or pump revolves rapidly the liquor is forced by the fan or pump into
the interior of the cop and is thrown outward through the same by the centri-
fugal force created by its rapid revolution.
The means for revolving the spindles in this improved apparatus is as
follows: Each spindle is provided near its upper end with a wharve constructed
in two discs s and s, one of which is fixed by a long boss on the spindle g
and the other or opposing half *, is capable of sliding up and down thereon.
The opposing faces of each disc are bevelled inward, so that the two together
form a V-grooved pulley, the movable disc being pressed against the fast one
by a spiral or other spring t or equivalent, which gives a certain amount of
elasticity thereto, sufficient to cause the two beveled surfaces to grip the strap
or belt, which is of a rectangular form in section and set cornerwise.
The spindles are preferably arranged in groups of, say, forty-eight or
other preferred number in four parallel lines of twelve spindles each, and are
placed so closely together that one short endless strap or belt passing between
the first and second rows, then around a grooved carrier-pulley provided with a
tension device, as *, and returning between the third and fourth rows and
around a grooved driving-pulley at the opposite end and back again, will drive
the whole group, as shown in Fig. 3.
Each cop-carrier is preferably made of, say, three wires, fixed in a ferrule r
at one end and bellied out slightly in the centre to give a better hold on the
inside of the cop and all united together so as to form a point at the other end.
To fix the open ends of these wires in the ferrule, I employ a short boss or plug
made with three longitudinal grooves on the outside . Fig. 10, to receive the
wires and keep their ends apart, and the wires are laid in these grooves and
inserted in the lower end of the ferrule r and fixed by soldering or otherwise.
The upper end of the ferrule is made slightly conical and the lower
end of the fan-casing similarly conical, so that the. cop-carriers can be fixed by
simply jamming them fast into the conical hole in the lower end of the fan-
casing and removed therefrom by means of a small instrument in the shape of
a lever inserted between the latter and a and a flange with which the lower end
of the ferrule is provided for that purpose.
The spindle above the fan is enclosed in a fixed tube r', the lower end of
which carries a ring w, provided with fixed vanes on the inside, the lower edge
of this ring nearly touching the upper edge of the revolving centripetal fan or
pump g. so as to prevent the "swirling" of the liquor, which would otherwise
take place. The upper end of this fixed tube extends through the ball-bear-
ings and inside the inverted cup o, before named, which is fixed on the
spindle, so that there is no possibility of oil from the said bearing running down
the spindle and so injuring the cops. The extreme upper end of the spindle g
is provided with a cupped shaped step or bearing running on a diamond point
at the bottom of an adjusting screw y.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
:-
1. An apparatus for dyeing, bleaching or otherwise treating with liquids cops
of yarn, that is constructed by a combination of any convenient number of open

page_text: vats or cisterns as a arranged in juxtaposition under a framing as 6 that is
provided with rails, a movable carriage thereon as d with depending guide-rods
supporting a frame as f carrying a group of spindles with their cop-carriers
and means for revolving and raising or lowering the same, and a centripetal fan
or pump with curved blades on each of said spindles all substantially as and
for the purpose herein before described.
2. In apparatus for dyeing bleaching or otherwise treating with liquids cops
of yarn, the combination with a frame as band carriage d of a frame as f
carrying a group of spindles placed in parallel rows, whose upper ends are fitted
with grooved pulleys and revolved by means of an endless band passing between
said pulleys and around driving pulleys at either end of the aforesaid parallel
rows of spindles said band being provided with an adjustment to take up stretch
substantially as described and shown on the drawings.
