Abstract
Abstract A control circuit for producing signals which change the normal movement of control cards, and the like, in knitting machines. The circuit includes a pair of decade counters with the count terminals of one sewing as output terminals and cross connected via a distributor with the count terminals of the other, serving as input terminals.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
Saving motion apparatus for controlling the stepping operation of moveable control means such as control cards, control chains and the like on flat knitting machines, said apparatus comprising a crosswise distributor (7) including a plurality of crossed contact strips (8,9) and plugs (10) for selectively connecting said contact strips, a first decade counter (3) having plural sequentially activated output connections (0''-9''), and a second decade counter (5) having a plurality of input connections (0''''-9''''), the connections of the two decade counters being arranged along different sides of a crosswise distributor (7) and connected to different groups of said strips respectively in such a manner that plug connections can be made at desired contact strip intersections of the crosswise distributor for causing a control signal to occur at predetermined counts, means for causing changes in the count of said counters in accordance with movement of said control means, and means responsive to said control sIgnals to produce a signal which serves to extinguish the normal stepping operation of the control means and to substitute a different stepping operation.
Claim 2
Dependent Claim
177 words
Saving motion apparatus for controlling the stepping operation of moveable control means such as control cards, control chains and the like on flat knitting machines, said apparatus comprising a crosswise distributor (7) including a plurality of crossed contact strips (8,9) and plugs (10) for selectively connecting said contact strips, a first decade counter (3) having plural sequentially activated output connections (0''-9''), and a second decade counter (5) having a plurality of input connections (0''''-9''''), the connections of the two decade counters being arranged along different sides of a crosswise distributor (7) and connected to different groups of said strips respectively in such a manner that plug connections can be made at desired contact strip intersections of the crosswise distributor for causing a control signal to occur at predetermined counts, means for causing changes in the count of said counters in accordance with movement of said control means, and means responsive to said control sIgnals to produce a signal which serves to extinguish the normal stepping operation of the control means and to substitute a different stepping operation.
Claim 3
Dependent Claim
31 words
Saving motion apparatus according to claim 1, wherein said decade counters are resettable to zero in response to the positioning of a control card corresponding to completion of a knitting process.
Claim 4
Dependent Claim
32 words
Saving motion apparatus according to claim 1, wherein manual switching means (29,30) is provided for supplying of a pulse to the decade counters (3,5) and for the resetting of the decade counters.
Claim 5
Dependent Claim
26 words
Saving motion apparatus according to claim 1, wherein diode plugs are provided at various points of intersection of said crosswise distributor to obtain said control signals.
