rows of pins may range from about 3 4 in to 21 4 in the slot 6 must be of sufficient breadth to permit the knitted fabric to emerge through it in my typical example the minimum is about 1 4 in preferrably the frame is made of molded plastic with pins 8 of the type shown in fig5 a however it may be made of wood and the pins may be of the barbed escutcheon pin type shown in fig5 b this type pin may also be cast in the molded plastic variable spacing means are provided for holding the members 2 4 apart the lengths of the stitches are governed by the distance between the two parallel rows of pins 8 in order to permit the standardization of patterns for various articles the spacing means is made such that the members 2 4 are held apart by any one of several fixed but selectable distances the preferred form particularly when the frame is made of molded plastic is that shown in fig3 a and 3b in member 2 there is a seat 10 having an arcuate base and in member 4 there is a cavity 12 in which is a fixed detent 14 a stitch selector 16 has an arcuate base 18 which fits and is journaled in seat 10 the other end of stitch selector 16 has a series of notches 20 whose bottoms lie on a cam surface that is eccentric to the center of arcuate portion 18 to facilitate adjustment each stitch selector.
