Improvements in Spindles or Skewers for Holding Yarn during
Dyeing, Bleaching, and similar Operations.
I, WALTER COVENTRY, of Boutirka, Moscow, Russia, Engineer, do hereby declare
the nature of this invention to be as follows:
My said invention relates to improvements in spindles or skewers for holding
yarn while being dyed bleached washed or otherwise treated.
A skewer for instance such as is at present used for holding cops of yarn in one
process of dyeing is made hollow and is perforated in such a way that lye liquor
may be forced from the interior of the hollow skewer through the perforations into
the body of the cop, or in some operations the course of the dye may be reversed so as
to proceed from the cop to the interior of the spindle.
Spindles or shafts for warp dyeing supported at both ends are constructed in a
similar manner.
It has been found that skewers and spindles made in the before described manner
are so weakened by the perforations that the spindles or skewers are frequently
damaged by the rough treatment they receive.
According to my said invention I use a spindle or skewer having grooves instead
of perforations. The said grooves communicate in the case of a skewer with a
cavity formed in one end of the skewer through which liquids or gases may be
forced or drawn through the cop.
In the case of a spindle or shaft for warps supported at both ends a cavity com-
municating with the grooves may be formed in one or both ends as may be desired.
In one form of my said invention the grooves are straight and form longitudinal
flutings in the spindle.
In another form of my said invention the grooves are spiral and form in effect
a multiple screw thread of comparatively quick pitch.

page_text: 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:
My said invention relates to improvements in spindles and skewers for holding
yarn while being bleached washed dyed or otherwise treated.
A skewer for holding cops of yarn in the process of dyeing is according to the
usual practice, made hollow and is perforated in such a way that dye liquor may be
forced from the interior of the hollow skewer through the perforations into the
body of the cop in some operations the course of the dye is reversed, i.c. it is
sucked through the cop into the interior of the spindle.
Spindles for warp dyeing supported at both ends are likewise made hollow and
are similarly perforated for the same purpose.
It is found that skewers and spindies made in the before described manner are
so weakened by the perforations that they are frequently damaged by the rough
treatment they receive at the bands of workpeople.
According to my said invention I make the spindle or skewer with grooves
instead of perforations. The said grooves communicate with a cavity formed in
one or both ends through which liquids or gases may be forced or drawn through
the cop or warp. In one form of my said invention the grooves are straight and
form longitudinal flutings in the skewer or spindle. In another form the grooves
are spiral and form in effect a multiple screw thread of comparatively quick pitch.
The accompanying drawings show the invention in various forms.
Fig. 1 is a side elevation of a cop skewer for holding yarn in the form of cops.
Fig. 2 is an end view.
Fig. 3 is a sectional elevation. The dotted line in this figure indicates the
contour of the cop.
The end of the skewer is formed as a cavity communicating at a¹ with the
longitudinal flutings or grooves of the skewer.
Fig. 4 is a similar skewer in which the grooves run spirally or screw-like along
the skewer.
Fig. 5 is a parallel spindle for holding yarn wound on perforated tubes or
bobbins.
Fig. 6 is a similar spindle with spiral grooves.
Fig. 7 is a parallel spindle with longitudinal flutings communicating, with a
cavity in one or both ends.
Fig. S is a parallel spindle with spiral grooves also communicating with cavities
in one or both ends of the spindle.
The forms illustrated in Figs. 7 and 8 are intended to be used for yarn in the
form of warps as indicated by dotted lines in Fig. 8.
The sizes of the spindles or skewers are of course made to correspond to the sizes
of the cops or bobbins or the quantity of warp to be treated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
:-
A spindle or skewer for holding yarn in dyeing bleaching and the like operations
having external grooves communicating with internal cavities in one or both ends
substantially as hereinbefore set forth and shown in the cecompanying drawings.
