Abstract
Abstract This disclosure relates to a knitting machine which includes a needle bed having a plurality of needles mounted thereon in sideby-side relation. Also mounted on the needle bed for traversing movement is a carriage. The carriage is provided with a pair of mechanical data storage dials one of which has needle setting arms thereof set in accordance with the pattern of a data carrier and the other of which has the arms thereof already set with the arms set in needles as the carriage traverses the needle bed. The data carrier may either be in the form of a preprinted program sheet or a base sheet adapted to have placed thereon by the individual the desired pattern data.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A system for selecting needles of a knitting machine of the type including a needle bed supporting a plurality of needles disposed in side-by-side relation and a carriage mounted on said needle bed for movement transversing said needle, a mechanical data storage dial carried by said carriage and including a plurality of arms settable to actuate the needles in a Pattern, a data carrier associated with said needle bed for traversing by said carriage, and control means responsive to said data carrier for automatically setting said arms, said control means including a reading head carried by said carriage for scanning said data carrier, pulse generator means carried by said carriage for generating an interval pulse when said carriage traverses a distance equal to the spacing of adjacent needles, and circuit means including a gating circuit connected to said reading head and said pulse generator means for transmitting a signal generated by said reading head only in the simultaneous presence of an interval pulse from said pulse generator means, and arm setting means operable in response to said signal to set a corresponding arm of said data storage dial.
Claim 2
Independent Claim
188 words
A system for selecting needles of a knitting machine of the type including a needle bed supporting a plurality of needles disposed in side-by-side relation and a carriage mounted on said needle bed for movement transversing said needle, a mechanical data storage dial carried by said carriage and including a plurality of arms settable to actuate the needles in a Pattern, a data carrier associated with said needle bed for traversing by said carriage, and control means responsive to said data carrier for automatically setting said arms, said control means including a reading head carried by said carriage for scanning said data carrier, pulse generator means carried by said carriage for generating an interval pulse when said carriage traverses a distance equal to the spacing of adjacent needles, and circuit means including a gating circuit connected to said reading head and said pulse generator means for transmitting a signal generated by said reading head only in the simultaneous presence of an interval pulse from said pulse generator means, and arm setting means operable in response to said signal to set a corresponding arm of said data storage dial.
Claim 3
Dependent Claim
42 words
A needle selecting system according to claim 1 wherein said circuit means includes a selectively operable inverting switch for providing said signals in inverted relation to said data carrier and provide a pattern which is the negative of said data carrier pattern.
Claim 4
Dependent Claim
30 words
A needle selecting system according to claim 1 wherein said reading head is a photo-electronic reading head responsive to reflected light and includes a light source and a photo-electric transducer.
Claim 5
Dependent Claim
31 words
A needle selecting system according to claim 1 wherein said pulse generator means includes a second reading head carried by said carriage, and fixed interval markings carried by said needle bed.
Claim 6
Dependent Claim
44 words
A needle selecting system according to claim 1 wherein said circuit means includes a multivibrator of the tye which changes state when an output signal of said reading differs from a next preceeding signal simultaneously with the presence of one of said interval pulses.
Claim 7
Dependent Claim
27 words
A needle selecting system according to claim 5 wherein said multivibrator is of the type which automatically resets at the end of a predetermined maximum operated time.
Claim 8
Dependent Claim
55 words
A needle selecting system according to claim 1 wherein said carriage is mounting on said needle bed for back and forth movement, there are two of said data storage dials each operable in one direction of movement only of said carriage with that data storage dial which is inoperable being reset by said control means.
Claim 9
Dependent Claim
51 words
A needle selecting system according to claim 7 wherein there are separate ones of said arm setting means associated with each of said data storage dials, and said circuit means includes a selector switch for selecting the appropriate arm setting means in accordance with the direction of movement of said carriage.
Claim 10
Dependent Claim
28 words
A needle selecting system according to claim 1 wherein said data carrier is in the form of a grid bearing sheet suitable for having a pattern applied thereto.
Claim 11
Dependent Claim
81 words
A needle selecting system according to claim 1 wherein said knitting machine is of the type for selectively applying threads of different colors, said data carrier is of multiple colors in accordance with the different colors of thread, there are a plurality of said reading heads each responding to a different one of a plurality of selected colors, and said circuit means includes a color data store for selectively presenting to selected needles a thread in accordance with said data carrier.
