Abstract
Abstract A time delay is provided between the end of one sewing cycle and the beginning of the next sewing cycle to provide a sufficient delay between sewing cycles that the operator can reposition the article being sewn. The time delay may be adjusted to suit the skill of the operator and a machine-operated switch automatically energizes a time delay relay upon the completion of a sewing cycle.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
155 words
Cycle control means for a sewing machine having an actuator lever shiftable to an operative position for initiating a stitching cycle, a member movable to a predetermined position upon completion of a stitching cycle, and means to stop operation of said sewing machine upon completion of a stitching cycle, said cycle control means being selectively operable to continuously repeat successive sewing cycles, and comprising operator controlled switch Means for starting and stopping said cycle control means, actuator means operable to move said actuator lever to said operative position, machine operated switch means operable by said sewing machine member upon completion of a sewing cycle, and a time delay relay interposed between said machine operated switch means and said actuator means for providing a predetermined delay between the end of one sewing cycle and the beginning of the next successive sewing cycle as long as said operator controlled switch means is maintained in the starting position.
Claim 2
Dependent Claim
155 words
Cycle control means for a sewing machine having an actuator lever shiftable to an operative position for initiating a stitching cycle, a member movable to a predetermined position upon completion of a stitching cycle, and means to stop operation of said sewing machine upon completion of a stitching cycle, said cycle control means being selectively operable to continuously repeat successive sewing cycles, and comprising operator controlled switch Means for starting and stopping said cycle control means, actuator means operable to move said actuator lever to said operative position, machine operated switch means operable by said sewing machine member upon completion of a sewing cycle, and a time delay relay interposed between said machine operated switch means and said actuator means for providing a predetermined delay between the end of one sewing cycle and the beginning of the next successive sewing cycle as long as said operator controlled switch means is maintained in the starting position.
Claim 3
Dependent Claim
25 words
Cycle control means according to claim 1 wherein said actuator means comprises a pneumatic cylinder operatively connected to said actuator lever of said sewing machine.
Claim 4
Dependent Claim
57 words

Claim 5
Dependent Claim
38 words
Cycle control means according to claim 1 wherein said time delay relay includes adjustment means for varying the length of time delay between the completion of one sewing cycle and the beginning of the next successive sewing cycle.
