This invention relates to apparatus for use in

The carriage is provided with means by which
gripped upon lowering of the carriage and can
be removed when the carriage is raised. The
spindles on which cores, such as bobbins, cops,
spools, etc., are mounted for rotation, so» that
yarn may be wound thereon. More particularly,
the invention is concerned with a novel appa
ratus by the use of which full cores may be re
moved from the spindles of such a machine and
empty cores may be mounted on the spindles, the
carriage also carries means for supporting one or
more empty cones in such relative positions that
by lowering the carriage, such empty cores can
be mounted on the spindles. 'I'he new machine
includes numerous other features to be described
later, which facilitate its use.
,For a better understanding of the invention,
reference may be had to the accompanying draw
new apparatus being of simple, inexpensive con
struction and easy to operate, so that it can be
employed efficiently by an operator who does not
possess a high degree of manual dexterity. The
new apparatus may be utilized for dofiing and
donning textile machines of various kinds, as, for
