Abstract

Abstract A knitting device has a needle bed consisting of a plurality of equidistantly spaced parallel needles and a sinker the needles being held between two depressor plates which form location points for a locking bar which in use closes the barbs of the needles when the sinker has picked up a row of stitches by movement along the needle bed so that said row of stitches can be moved to the bottom of the needles to form a row of stitches in a knitted article.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 139 words
A knitting device comprising a needle bed, a plurality of equidistantly spaced substantially paralled barbed needles in said needle bed, a depressor bar for closing the barbs of the needles in said needle bed, at least two depressor plates one depressor plate disposed at each end of said needle bed, a retaining notch in each depressor plate and a sinker whereby on rotation and movement of the sinker along said needle bed said sinker sequentially draws working yarn or material from between the needles and on completion of a row of stitches along said needle bed the barbs of said needles may be releasably closed by locating the depressor bar between said retaining notches so that said row of stitches may be passed to the bottom of said needles to form a row of stitches in a knitted article.
Claim 2
Dependent Claim 139 words
A knitting device comprising a needle bed, a plurality of equidistantly spaced substantially paralled barbed needles in said needle bed, a depressor bar for closing the barbs of the needles in said needle bed, at least two depressor plates one depressor plate disposed at each end of said needle bed, a retaining notch in each depressor plate and a sinker whereby on rotation and movement of the sinker along said needle bed said sinker sequentially draws working yarn or material from between the needles and on completion of a row of stitches along said needle bed the barbs of said needles may be releasably closed by locating the depressor bar between said retaining notches so that said row of stitches may be passed to the bottom of said needles to form a row of stitches in a knitted article.
Claim 3
Dependent Claim 16 words
A knitting device according to claim 1 wherein the needles are of a flexible plastics material.
Claim 4
Dependent Claim 73 words
A knitting device according to claim 1 wherein the sinker consists of a shaft having a pair of opposed ends, a hook formed on one of said ends of said shaft, a bushing on said shaft in proximate relation to said hook, said bushing having a tapered leading thread, said thread having a larger root diameter adjacent said hook and a smaller root diameter as it approaches the other end of said shaft.
Claim 5
Dependent Claim 27 words
A knitting device according to claim 3 wherein the angle of the threads relative to the axis of the shaft of said sinker varies around the circumference.
Claim 6
Dependent Claim 21 words
A knitting device according to claim 1 wherein further depressor plates are disposed intermediate the two ends of said needle bed.
Claim 7
Dependent Claim 141 words
A knitting device comprising a sinker, a needle bed formed of a plurality of plastics barbed needles, two depressor plates one disposed at each end of said needle bed, a retaining bar securing said plastics needles and said depressor plates together and a retaining notch in each of the said depressor plates, the said sinker having a shaft which forms a depressor bar which sinker in use is adapted on rotation and movement along said needle bed to sequentially draw working yarn from between the said plastics needles and on completion of the loops of a row the shaft forming the depressor bar is moved to a retaining position within the said notches and extending between the said depressor plates in which the barbs of the said needles are held closed allowing the yarn to be moved over the plastics needles.
Claim 8
Dependent Claim 141 words
A knitting device comprising a sinker, a needle bed formed of a plurality of plastics barbed needles, two depressor plates one disposed at each end of said needle bed, a retaining bar securing said plastics needles and said depressor plates together and a retaining notch in each of the said depressor plates, the said sinker having a shaft which forms a depressor bar which sinker in use is adapted on rotation and movement along said needle bed to sequentially draw working yarn from between the said plastics needles and on completion of the loops of a row the shaft forming the depressor bar is moved to a retaining position within the said notches and extending between the said depressor plates in which the barbs of the said needles are held closed allowing the yarn to be moved over the plastics needles.
