(57) A device for enabling and disabling of needle-carrier rods and piercer-carrier rods
according to a presettable program is described, in particular for a shuttle embroidery
machine.
The device includes disengageable means for coupling said needle-carrier rods and
said piercer-carrier rods to a single drive bar for reciprocating motion, each of
said means being actuated by two rod assemblies, movable against the bias of resilient
means, each of said rods of each of said assemblies extending rearwardly and laterally
of said needle-carrier rods and of said piercer-carrier rods and being provided, at
the lower end thereof, with substantially radially protruding portions, the protruding
portions of the rods associated with the needle-carrier rods being offset relative
to the protruding portions of the rods associated with the piercer-carrier rods, there
being further provided means for simultaneous disabling of all the needle-carrier
rods cooperating with the projecting parts of the rods associated therewith, and means
for simultaneous disabling of all the piercer-carrier rods cooperating with the projecting
parts of the rods associated therewith, as well as disengageable means for temporarily
locking in the inactive condition the rods associated with the needle-carrier rods
and the rods associated with the piercer-carrier rods, said locking means separately
cooperating with each of said protruding portions of the rods associated with the
needle-carrier rods and of the rods associated with the piercer-carrier rods.
