As shown in Fig. 3 I have indicated on a'reduced
scale my cylinder with a package, cheese, or
wound material 15 thereon, this winding opera
tion being performed after the cylinder has been
expanded to its greater radial dimensions, as
shown in Fig. 2. For this purpose, a pair of cone
shaped members having a base or plate 20 and
projecting conical forms 2| are ?tted into the op
posite open ends of the cylinder I, forcing the
cylinder into expanded position as the open ends
of the cylinder slide along the bevelled faces of
the conical portions 2| at opposite ends, until the
cylinder is in expandaed position with the top and
has been an objectionable dii?culty on spools or
yarns, cheeses, packages, and the like, whether
the material being dyed is of cotton, rayon, silk,
or synthetic ?brous material.
While I prefer at present to utilize stainless
steel for the collapsible and expansible spindle
or cylindrical shell, because of the known capac
ity of resiliency, yield, and spring of the same,
it will be appreciated that any other metal, al
loy, or synthetic plastic such as Koroseal, Vin
ylite, Bakelite, or the like may be employed if
Also, while I prefer to embody the collapsible
and expansible spindle in the form of a cylin
drical shell or tubular member, as this is most
suitable and customary for use in winding yarns
and ?bres of various kinds thereon, I may utilize
other forms suitable for different kinds of goods
to be supplied to and carried thereby.
An expansible and contractible spindle of the
kind described, having a cylindrical body por
