  • Patent number: 4393668
    Abstract: A knitting frame comprising two spaced, flat, parallel bars having upstanding pins is provided with a support. The support includes a base plate, hook-shaped locking members rising from the base plate and curved sustaining members so spaced from the locking members that when one edge of one bar is against the locking members, the other edge will rest on the sustaining members in such a position that gravity will hold it against the locking members. The support also includes an upstanding knotting pin having notches in its top and sides. It is used to join yarn used in knitting.

  • Patent number: 3967467
    Abstract: A manual knitting frame comprising two parallel elongated bars which are held apart to leave a relatively narrow slot between them. Each bar carries a row of uniformly spaced relatively short upright pins over which the yarn is looped during the knitting. To vary and standardize the length of the stitches, means are provided for spacing the bars apart by any one of several fixed but selectable distances. Removable pattern strips located beside the rows of pins are used to guide the knitting of various articles.
