Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
In a programmable knitting machine the combination comprising a needle bed wherein needles are supported in side by side relation, needle selecting means including a carriage movable on the needle bed for causing the needles during each movement thereof in one direction or another to knit a course of fabric, a program card and a card reader for reading rows of instruction marks on the card for a design to be formed in a fabric in courses corresponding to said rows, electronic control means responsive to the reader and operably connected to the needle selecting means for controlling the knitting of fabric pursuant to the instruction marks, switch means operably connect to the electronic means, the switch means being manually operable to modify the operation of the electronic control means and thereby control the order in which design rows are knit into courses on the machine, and a device responsive to the operation of the switch means for visually indicating a knitting order as prescribed by the switch means for the design rows.
Claim 2
Dependent Claim
173 words
In a programmable knitting machine the combination comprising a needle bed wherein needles are supported in side by side relation, needle selecting means including a carriage movable on the needle bed for causing the needles during each movement thereof in one direction or another to knit a course of fabric, a program card and a card reader for reading rows of instruction marks on the card for a design to be formed in a fabric in courses corresponding to said rows, electronic control means responsive to the reader and operably connected to the needle selecting means for controlling the knitting of fabric pursuant to the instruction marks, switch means operably connect to the electronic means, the switch means being manually operable to modify the operation of the electronic control means and thereby control the order in which design rows are knit into courses on the machine, and a device responsive to the operation of the switch means for visually indicating a knitting order as prescribed by the switch means for the design rows.
Claim 3
Dependent Claim
29 words
The combination of claim 1 wherein the switch means includes a switch operable to cause the same design row to be formed in successive courses as fabric is knit.
Claim 4
Dependent Claim
106 words
The combination of claim 1 wherein said device operably connects with the electronic control means and the switch means includes a switch movable into one position to cause said device to successively and cyclically indicate the instruction rows and movable from said one position to cause said device to hold the indication display at that time, the electronic control means being effective to cause the row indicated to be formed when knitting is begun after removal of the switch from said one position and as knitting is continued to cause successive rows on the card to be formed in the fabric and indicated on said device.
Claim 5
Dependent Claim
28 words
The combination of claim 3 wherein the successive indications of rows on said device after the operation of said switch occurs slowly at first and thereafter more quickly.
Claim 6
Dependent Claim
23 words
The combination of claim 3 wherein the switch is effective to change the indication on said device unless the carriage is in mid-course.
Claim 7
Dependent Claim
20 words
The combination of claim 3 wherein the display is immediately stepped to the next indication when the switch is operated.
Claim 8
Dependent Claim
75 words
The combination of claim 1 wherein said device indicates design rows, the switch means includes a switch momentarily operable and effective whenever so operated to cause a new indication to appear on said device, the electronic control means being effective when knitting is begun after operation of the switch to cause the last row indicated to be knit and as knitting is continued to cause successive rows to be knit and indicated on said device.
Claim 9
Dependent Claim
23 words
The combination of claim 7 wherein the switch is effective to change the indication on said device unless the carriage is in mid-course.
Claim 10
Dependent Claim
20 words
The combination of claim 7 wherein the display is immediately stepped to the next indication when the switch is operated.
Claim 11
Dependent Claim
92 words
The combination of claim 1 wherein the switch means includes one or more switches operable to cause said device to successively and cylically indicate the instruction rows in the order prescribed for knitting or in reverse order at the time of operation and movable after such operation to cause said device to hold the indication displayed at that time, the electronic control means being effective to cause the held row to be formed when knitting is thereafter initiated and as knitting is continued to cause successive rows to be knit and indicated.
Claim 12
Dependent Claim
24 words
The combination of claim 1 wherein the switch means includes a switch operable to effect a reversal in the order of knitting design rows.
Claim 13
Dependent Claim
30 words
The combination of claim 11 wherein the switch means also includes a switch operable to cause the same design row to be formed in successive courses as fabric is knit.
