Abstract: An improved system and associated method is disclosed for positive feeding of multiple strands of yarn from spools using a single motor drive within a hose reinforcement knitting machine of the type having a central knitter head with reciprocating needles that stitch a reinforcement web pattern around flexible hose moving through the central axis of the machine. The positive yarn feeding system comprises a feeder head assembly attached to rotating framework of the knitting machine coaxially with the knitter head. The feeder head assembly includes a circular support plate having an axial opening therethrough and a plurality of positive feeder units, one for each of the yarn strands intended for knitting. The feeder units are arranged in a radial pattern about the periphery of the support plate and interconnected for concurrent rotation by a coupling belt extended about upper wheels on the units.

Abstract: An improved clip system is disclosed for holding parallels in place against the respective jaws of a vise head. The clip system comprises a pair of specially configured clip members adapted to releasably engage a notched slot formed along the side edges of the jaw on the rearward surface thereof, each slot being accessible for engagement through corresponding opening formed in the forward comers of the vise head. Each clip member is integrally formed having a hook section inwardly disposed at an intermediate position along its length to engage the notched slot in a forwardly direction and a cap section inwardly disposed at the forward end of the clip member to clamp flush against the parallel and hold it firmly against the jaw when the hook section is engaged with the notched slot.

Abstract: An improved clip system is disclosed for holding parallels in place against the respective jaws of a vise. The clip system comprises a pair of specially configured clip members adapted to releasably engage a retaining plate mounted flush between the jaw and the vise, the retaining plate being formed having a slotted tab extended from either side of the plate for engaging a respective one of the clip members. Each clip member is integrally formed having a hook section inwardly disposed at an intermediate position along its length to engage the slotted tab in a forwardly direction and a cap section inwardly disposed at the forward end of the clip member to clamp flush against the parallel and hold it firmly against the jaw when the hook section is engaged with the slotted tab. The clip members are further formed each having an outwardly disposed leg section intended to deflect in a forward direction thereby releasing the clip member from engagement with the retaining plate and allowing removal of the parallel.
