  • Patent number: 4501133
    Abstract: A dual needle arrangement has a pair of needles each having a tip and a rear end, a flexible cord connected between the rear ends of the needles, and an eye in the cord between the rear ends. A filament can be laid in by being threaded through the eye and then pulled through the row behind the needle. Both needles can be knitting or crocheting needles. When one is a hook-type crocheting needle and the other is a pointed knitting needle these two needlework styles can be combined to produce a unique type of needlework, and the changeover from one style to the other is easy and not complicated by the inlay filament. The cord can be formed of metal wires, or it can be of a flexible synthetic resin in which case the eye is formed by splicing in the cord. This eye can also be formed by flattening a portion of the cord between the two rear ends and slitting this flattened portion.
