The present invention relates to an improved device for
[applying travellers to the rings of spinning and twisting
machines during simultaneous drawing-in of the yarn or
thread.
In known devices in which the ‘applying of the traveller
to the ring results by applying a tool fork to the ring
?ange with ‘a subsequent push-on movement of a movable
tongue member arranged on the tool fork, the yarn which
extends vertically with respect to the ring is manually
brought into engagement with ‘a hook member arranged
on the device and is deposited into 1a guide groove. This
travellers vas well as for the mounting of the travellers onto
the spinning ring, can be carried out in a purely mechani
cal manner Without the necessity of employing further
auxiliary means.
Still further objects and the entire scope of applicability
of the present invention will become apparent from the
detailed description given hereinafter. It should be under
stood, however, that the detailed description and speci?c
example, while indicating ‘a preferred embodiment of the
invention, is given by way of illustration only, since vari
ous changes and modi?cations within the spirit and scope
of the invention will become apparent to those skilled in
the art from this detailed description.

If the trigger member 3 is further pressed into the

For the receipt of a number of travellers a supply rod
