  • Patent number: 5413150
    Abstract: A frame (20) having a number of yarn holding clips (30) attached on an outside edge for looping yarn in a first direction around adjacent parallel clips to form a warp. A second number of opposed clips likewise mounted on the frame, permit a second looping yarn to be layered on top in a woof-like manner. The frame (20) has parallel sides and is preferably square or rectangular in shape. The clips (30) have legs (32), (34) and (36) that mate with the frame and an upstanding leg (38) provides the attachment point for the yarn. The clips are attached by nails (42) in the preferred embodiment or by spring tension in a third embodiment. A second embodiment provides a narrower upstanding leg (38) to pre-space the leg when the clips are touching each other. In a fourth embodiment, a frame having a multiplicity of rectangular frame cavities (50) is used. Into these cavities is inserted a yarn holding clip (30).

  • Patent number: 4881381
    Abstract: A method of forming a textile fabric using a frame (20) which has pegs (22) spaced apart around the perimeter with yarn wound a first direction (26) between parallel pegs forming a warp. Yarn is then wound a second direction (28) 90-degrees from the first directly on top creating a woof-like layer, but not interlaced. Yarn is crocheted in a chain stitch a first (30) and a second (32) diagonal or right-angled direction across the frame tying the warp and woof layers together into a fabric. Yarn is finally crocheted in a chain stitch through the perimeter of the textile joining the edges together into interlocked loops that will not unravel. The fabric is then removed from each peg by pulling the yarn upwardly off the peg by means of a crochet hook. The finished product results in a strurdy fabric having geometrical or other design patterns.
