Abstract
Abstract An input device for providing signals for controlling a knitting machine. The device includes a mechanical information storage means and a switch means responsive to the contents of the storage means to provide a signal corresponding to the stored information. The storage means is disposed for operation either manually by a machine operator or electromechanically in response to instructions provided by other components of the machine. The device is incorporated in a program reading apparatus to specify feeding direction of the program carrier on the knitting machine.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
88 words
A device for providing signals representative of an instruction for control of a knitting machine, comprising: a support member mounted on the knitting machine, a manually operable shiftable member supported on the support member for shifting movement between two positions, electromagnetic means energizable to shift the shiftable member from one to the other of said positions or vice versa, a drive circuit for energization of the electromagnetic means, and a switch disposed to be responsive to the position of the shiftable member to provide a corresponding output signal.
Claim 2
Independent Claim
88 words
A device for providing signals representative of an instruction for control of a knitting machine, comprising: a support member mounted on the knitting machine, a manually operable shiftable member supported on the support member for shifting movement between two positions, electromagnetic means energizable to shift the shiftable member from one to the other of said positions or vice versa, a drive circuit for energization of the electromagnetic means, and a switch disposed to be responsive to the position of the shiftable member to provide a corresponding output signal.
Claim 3
Dependent Claim
38 words
A device as claimed in claim 1 wherein the electromagnetic means is mounted on the shiftable member, and further comprising an element disposed on the support member for cooperation with the electromagnetic means to shift the shiftable member.
Claim 4
Dependent Claim
34 words
A device as claimed in claim 1 wherein the electromagnetic means is mounted on the support member, and the shiftable member includes an element cooperative with the electromagnetic means to shift the shiftable member.
Claim 5
Dependent Claim
18 words
A device as claimed in claim 3 wherein said element on the shiftable member comprises a permanent magnet.
Claim 6
Dependent Claim
35 words
A device as claimed in claim 4, wherein said switch comprises means responsive to a magnetic field for actuating said switch and is disposed to be operable by said permanent magnet on said shiftable member.
Claim 7
Independent Claim
159 words
A device for providing electric signals representative of patterning instructions in a knitting machine having a support for supporting thereon a program carrier which carries thereon patterning instructions in rows and columns, an electrically controlled bidirectional incremental drive means for driving the support to feed the program carrier thereon in one or the other direction, and an electronic reading member disposed to read a row of patterning instructions on the program carrier, wherein the improvement comprises: a switch means for providing an output signal for control of the drive means controlling the feeding direction of the program carrier on the support, a switch actuator adapted to be positioned in either of two positions, one operative and one inoperative for said switch, said switch actuator being manually shiftable between said two positions, and means for shifting the switch actuator between said two positions in response to readings by the reading member of a particular instruction mark on the program carrier.
Claim 8
Independent Claim
159 words
A device for providing electric signals representative of patterning instructions in a knitting machine having a support for supporting thereon a program carrier which carries thereon patterning instructions in rows and columns, an electrically controlled bidirectional incremental drive means for driving the support to feed the program carrier thereon in one or the other direction, and an electronic reading member disposed to read a row of patterning instructions on the program carrier, wherein the improvement comprises: a switch means for providing an output signal for control of the drive means controlling the feeding direction of the program carrier on the support, a switch actuator adapted to be positioned in either of two positions, one operative and one inoperative for said switch, said switch actuator being manually shiftable between said two positions, and means for shifting the switch actuator between said two positions in response to readings by the reading member of a particular instruction mark on the program carrier.
Claim 9
Dependent Claim
42 words
The improvement as described in claim 6 wherein the program carrier includes a pair of columns corresponding to directions of feeding the program carrier on the support, particular marks in said columns being instructive of the feeding direction of the program carrier.
