  "abstract": "A lock for a knitting machine which permits guiding tracks thereof to be quickly exchanged in groups or as a unit. The tracks are removably secured to ring segments by the lock. The lock includes a first stud disposed normal to the track and received in a first bore in the ring segment extending inwardly from a first face of the ring segment. A second, headed stud, extends into a second bore, extending inwardly from the second, opposite face of the ring segment. The first and second bores partially overlap and communicate at their inner ends. Interfitting cam and notch configurations are provided on the confronting, inner ends of the studs, whereby they are secured together against separation by turning one stud relative to the other.",
  "claims": [
    "1. In a circular knitting machine having a ring segment to which guiding tracks are removably affixed, the improved locking device for holding the tracks on the segment which comprises a first stud secured to the track and extending into a first bore in the segment from a first track side of the segment, a second stud extending into a second bore from the second, opposite side of the segment, the two bores being parallel and at least partially overlapping, the two bores communicating at their inner ends, and selectively interengaging formations on the confronting inner ends of the studs whereby the studs may be quickly secured together against separation and released from each other.",
    "2. Apparatus according to claim 1, wherein the said formation on one of the studs is a cross slot, and the said formation on the other stud is a radially projecting helical ramp engageable within said cross slot, one of said studs being rotatable relative to the other, and means retaining the second stud from travel axially toward the first stud.",
    "3. Apparatus according to claim 2, wherein the first stud is the one which is cross slotted, and the second stud is the one carrying the radially projecting helical ramp.",
    "4. Apparatus according to claim 3, wherein the second stud is headed at its outer end, said head engaging the second side of the ring segment and preventing inward axial travel of the second stud.",
    "5. Apparatus according to claim 1, wherein the ring segment has a plurality of guiding tracks thereon, the respective tracks being held on the segment by identical locking devices."
