This invention relates to ‘cone holders for use
on knitting or other textile machines.
In knitting or other textile machines, where
the yarn or thread is wound on cones, the latter
will vary in length, degree of taper and diameter,
with the result that the machines have to be
adapted to the particular cone. It is, therefore,
an object of this invention to provide a cone

tion of the creel frame with which the bolt I I is
engaged. The upper end of the spring It bears
against the lower side of the sliding or ?oating
washer I4. Preferably the spring I6 is a rela
tively weak spring so that when a cone I ‘I, as
shown in Figure 1, is disposed in telescoping posi
tion over the washers I2 and I4, the lower or slid
ing washer I4 will move downwardly and auto10 matically adapt itself to the taper of the cone
