Abstract
A pattern contained in an information carrier is transferred to and stored in a pattern drum provided with feeler levers, a retaining guide, and a switch. Upon the movement of the lock over the needle bed, this pattern is then transferred to pushing rod jacks which in turn act upon the needles. The pattern can be suspended for a predetermined distance during an interruption phase while the pattern information itself is retained in the pattern drum, and rapid and reliable operation of the knitting machine is ensured by the use of resilient or articulated feeler levers having nose-like projections at their outer ends. To ensure proper guidance of the feeler levers, the retaining guide includes a needle-shaped portion extending into the vicinity of the switch.
Claims8
In a pattern device for a knitting machine having a needle bed, of the type including
- an information carrier,
- a pattern drum rotatable about an axis parallel to said needle bed,
- a plurality of feeler levers uniformly disposed about the circumference of said pattern drum, having forward ends nearest said information carrier and rearward ends remote from said information carrier, and selectively pivotable from a resting position against the outside surface of said pattern drum into an operative position,
- stop means for securing said feeler levers in said operative position, and
- means for enabling said information carrier to act selectively upon said forward ends of said feeler levers,
- the improvement which comprises:
- cam means for controlling and limiting a pattern-interruption phase,
- a retaining guide disposed adjacent to said pattern drum, and switch means actuated by said cam means for selectively causing said rearward ends of said feeler levers to pass within said retaining guide, said feeler levers being of a springy or articulated construction.
