Improvements in Spindles Used for Holding Yarn During Dyeing
and the like Operations.
I, WALTER COVENTRY, of The Elms, Macclesfield, Cheshire, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
My said invention relates to improvements in the spindles used for holding yarn
in the process of dyeing bleaching or otherwise treating yarn by percolation under
pressure (or by a vacuum) through the yarn in a wound state and is particularly
applicable to the treatment of yarn in the form of "cheeses."
As applied for example to the type of spindle described in my Patent Specifica-
tion No. 11491 of A.I. 1897 the spindle a (Figure 1) is formed with grooves as
described in my former patent A hollow socket 6 is screwed or otherwise attached
to the dyeing machine. The grooves or channels of the spindle open into the
socket for the passage of the dye liquor. One end of the spindle a is shouldered
down to a smaller diameter where it fits in the socket. The other end d of the
spindle is formed as a cap or head to hold on the yarn. A keep-plate, jacket, or
other like device in the dyeing machine is caused to bear against the head of the
spindle to prevent it being blown out of the socket when the dye liquor is forced
through. The spindle may also be secured in the socket by a screwed thread on
the shouldered part. When the yarn has been dyed the spindle is withdrawn and
the "
cheese" may be readily slid off the shouldered end of the spindle.
The socket at 6 and the head at a are externally formed as parts of cones so
as to more effectually seal the internal cavity in the "cheese" or in the perforated
paper or other tube on which it may be mounted.
Although I have herein described my said invention as applied to my patent
grooved or corrugated spindles it is to be understood that it is equally applicable
to other types of spindles as for example the ordinary tubular perforated spindle
as shown in Figure 2. In this case also the spindle barrel a is provided at one
end a with a conical swell and is shouldered at the other end to fit a socket b
having an external conical swell at 6'.
For pressure dyeing a spinde a such as shown in Figure 3 may be used. In
this example a thinner spindle connects the two heads one of which is solid
and coned externally as above described while the other is shouldered at to fit
the socket and is perforated as at and to give access for the dye liquor to
the interior of the tube y on which the yarn is wound.
For vacuum dyeing the spindles shown in Figures 1 and 2 are preferable in
order to prevent the collapse of the paper or other tube.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1. A spindle for holding yarn externally coned at one end in combination with

page_text: an externally coned socket substantially as and for the purpose set forth and
shown.
2.-A longitudinally grooved spindle a externally coned at one end and
shouldered down at the other end in combination with an externally coned socket b
substantially as and for the purpose set forth and shown.
3. A hollow tubular perforated spindle for holding yarn externally coned at
one end in combination with an externally coned socket substantially as and for
the purpose set forth and shown.
4. A solid spindle for holding yarn having enlarged ends one of which is
externally coned while the other is perforated and adapted to fit an externally
coned socket substantially as and for the purpose set forth and shown.
