Abstract
Abstract A semi-automatic crocheting tool has a chassis including a yarn-receiving assembly with a hook, a needle normally spaced from the hook, and means for selectively engaging and disengaging the needle from the hook. The tool has a counting feature which automatically counts the number of times the needle engages the hook, and thus keeps an accurate record of the number of stitches completed. Additionally, a manual counting device facilitates multiplying the maximum number of stitches up to which the automatic device can count, or, in the alternative, allows for both the number of stitches and the numbers of rows of stitches to be recorded.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A crocheting tool comprising a chassis including yarn-collecting means for receiving and retaining a segment of yarn, a needle slidably mounted in said chassis, positioning means adapted to reciprocate said needle relative to said chassis between a first position in engagement with said yarn-collecting means and a second position remote from said yarn-collecting means, and counting means mounted in said chassis for recording the number of reciprocations of said needle, said counting means comprising a rachet gear rotatably mounted to said chassis and having numerals sequentially printed at its periphery, a resilient actuator mounted to said needle and located to advance said rachet gear as said needle moves from said second position to said first position, and a pawl engaging said rachet gear, said pawl being constructed and arranged to prevent said rachet gear from counter-rotating as said needle moves from said first position to said second position.
Claim 2
Dependent Claim
148 words
A crocheting tool comprising a chassis including yarn-collecting means for receiving and retaining a segment of yarn, a needle slidably mounted in said chassis, positioning means adapted to reciprocate said needle relative to said chassis between a first position in engagement with said yarn-collecting means and a second position remote from said yarn-collecting means, and counting means mounted in said chassis for recording the number of reciprocations of said needle, said counting means comprising a rachet gear rotatably mounted to said chassis and having numerals sequentially printed at its periphery, a resilient actuator mounted to said needle and located to advance said rachet gear as said needle moves from said second position to said first position, and a pawl engaging said rachet gear, said pawl being constructed and arranged to prevent said rachet gear from counter-rotating as said needle moves from said first position to said second position.
Claim 3
Dependent Claim
56 words
Apparatus in accordance with claim 1 wherein said yarn-collecting means comprises a support arm including a recess, a hook pivotally mounted to said chassis in engaging relationship with said support arm, said hook and said recess combining to define a cavity and biasing means for urging said hook to remain normally adjacent to said support arm.
Claim 4
Dependent Claim
27 words
Apparatus in accordance with claim 2 wherein said hook further includes: translating means for receiving said needle and simultaneously urging said hook away from said support arm.
Claim 5
Dependent Claim
24 words
Apparatus in accordance with claim 3 wherein said translating means comprises a camming surface included on said hook in the path of said needle.
Claim 6
Dependent Claim
17 words
Apparatus in accordance with claim 1 wherein said counting means further comprises a manually operated indicating means.
Claim 7
Dependent Claim
34 words
Apparatus in accordance with claim 1 wherein said needle is comprised of a tubular member and includes an eye transverse to the axis of said tubular member at its end adjacent said yarn-collecting means.
Claim 8
Dependent Claim
56 words
Apparatus in accordance with claim 1 wherein said chassis further includes a longitudinally extending slot generally parallel to said needle, and said positioning means comprises a projection on said needle, said projection being slidingly engaged in said slot whereby reciprocation of said projection causes said needle to move between said first position and said second position.
Claim 9
Dependent Claim
45 words
Apparatus in accordance with claim 7 wherein said positioning means further comprises a stop-piece adjustably mounted within said slot and constructed and arranged so that said stop-piece limits the reciprocation of said needle as said needle moves from said first position to said second position.
Claim 10
Dependent Claim
164 words
A crocheting tool comprising a chassis, a needle slidably mounted in said chassis, a yarn-receiving assembly mounted to said chassis and adapted to selectively receive said needle, positioning means operable to reciprocate said needle relative to said chassis between a first position in engagement with said yarn-receiving assembly and a second position remote from said yarn-receiving assembly, a ratchet gear rotatably mounted to said chassis and having numerals sequentially printed at its periphery, a resilient actuator mounted to said needle and located to advance said ratchet gear as said needle moves from said second position to said first position, a pawl engaging said ratchet gear, said pawl being constructed and arranged to prevent said ratchet gear from counter-rotating as said needle moves from said first position to said second position, and a stop-piece adjustably mounted within said chassis and constructed and arranged so that said stop-piece limits the reciprocation of said needle as said needle moves from said first position to said second position.
