This invention relatesv to a full-fashioned or
straight knitting machine and more specially to
a special type of carrier adapted to be used on
any type of full-fashioned knitting machine.
In full-fashioned knitting‘machines there are
usually anywhere from 18 to 32' units connected
together in end to‘ end relation and all operating
of the unit will not be knitted where a defect has
occurred in the stocking blank for theunit.
It is, therefo-raan object of this invention to .
provide a carrier having a clamp means thereon
for clampinglyand releasably holding the yarn in
such a manner that it ‘can easily be engaged by
the:p_liers of the operator and brought down to
normal position with respect to the needle, with-‘
stocking blanks can be knitted in one operation.

November 28, 1939. A full-fashioned knitting
machine is equipped with a plurality of movable
