Control means for registration control device

Claim 1

IN A REPEAT CYCLE MACHINE OF THE TYPE INCLUDING ROTATABLE CUTTING MEANS, FEED ROLLS POSITIONED TO FEED SAID CUTTING MEANS A CONTINUOUS PIECE OF MATERIAL MARKED BY SPACED INDICIA, DRIVE MEANS FOR DRIVING SAID FEED ROLLS, MOTION TRANSMISSION MEANS FOR TRANSMITTING MOTION FROM SAID DRIVE MEANS TO SAID CUTTING MEANS SO THAT SAID CUTTING MEANS IS ADAPTED TO CUT SAID MATERIAL INTO PREDETERMINED LENGTHS, PHOTOELECTRIC SCANNING MEANS LOCATED AHEAD OF SAID CUTTING MEANS AND BEING RESPONSIVE TO THE INDICIA ON SAID PIECE OF MATERIAL BEFORE CUT, AND CONTROL MEANS INCLUDING A CONTROLLER AND A REVERSIBLE MOTOR MEANS CONTROLLED THEREBY AND CONNECTED TO SAID MOTION TRANSMISSION MEANS FOR MOVING THE POSITION OF SAID CUTTING MEANS RELATIVE TO SAID FEED ROLLS AND SAID INDICIA; THE IMPROVEMENT FOR MAINTAINING SAID CUTTING MEANS IN REGISTER WITH SAID INDICIA; SAID IMPROVEMENT COMPRISING A TIMER INCLUDING A SHAFT, MEANS COUPLING SAID SHAFT TO SAID CUTTING MEANS, A CYLINDRICAL INSULATOR MOUNTED ON SAID SHAFT FOR ROTATION THEREWITH, A FIRST ELECTRICAL CONDUCTOR SEGMENT MOUNTED ON SAID INSULATOR CIRCUMFERENTIALLY THEREOF AND EXTENDING SUBSTANTIALLY 180 DEGREES AROUND THE CIRCUMFERENCE OF SAID INSULATOR, SAID FIRST SEGMENT INCLUDING A LEADING EDGE, A SECOND ELECTRICAL CONDUCTOR SEGMENT MOUNTED ON SAID INSULATOR CIRCUMFERENTIALLY THEREOF IN PARALLEL SPACED RELATIONSHIP TO SAID FIRST SEGMENT AND EXTENDING SUBSTANTIALLY 60 DEGREES AROUND THE CIRCUMFERENCE OF SAID INSULATOR, SAID SECOND SEGMENT INCLUDING A LEADING EDGE DISPOSED IN SUBSTANTIAL ALIGNMENT WITH SAID LEADING EDGE OF SAID FIRST SEGMENT, A FIRST PAIR OF BRUSHES DISPOSED IN THE PATH OF SAID FIRST SEGMENT WHEREBY TO ESTABLISH A FIRST SWITCH WHICH IS CLOSED WHEN SAID FIRST PAIR OF BRUSHES ARE CONTACTED BY SAID FIRST SEGMENT AND OPEN WHEN THE FIRST PAIR OF BRUSHES ARE UNCONTACTED, A SECOND PAIR OF BRUSHES IN ALIGNMENT WITH SAID FIRST PAIR OF BRUSHES DISPOSED IN THE PATH OF SAID SECOND SEGMENT WHEREBY TO ESTABLISH A SECOND SWITCH WHICH IS CLOSED WHEN SAID SECOND PAIR OF BRUSHES ARE CONTACTED BY SAID SECOND SEGMENT AND OPEN WHEN THE SECOND PAIR OF BRUSHES ARE UNCONTACTED, A THIRD PAIR OF BRUSHES DISPOSED IN THE PATH OF SAID SECOND SEGMENT WHEREBY TO ESTABLISH A THIRD SWITCH WHICH IS CLOSED WHEN SAID THIRD PAIR OF BRUSHES ARE CONTACTED BY SAID SECOND SEGMENT AND OPEN WHEN THE THIRD PAIR OF BRUSHES ARE UNCONTACTED, SAID THIRD PAIR OF BRUSHES BEING SPACED CIRCUMFERENTIALLY FROM SAID SECOND PAIR OF BRUSHES AN ANGULAR DISTANCE SLIGHTLY GREATER THAN 60 DEGREES WHEREBY SAID SECOND SEGMENT IS ADAPTED TO BE POSITIONED INTERMEDIATE SAID SECOND AND THIRD PAIRS OF BRUSHES IN SPACED RELATION THERETO, THE RELATIONSHIP OF SAID CUTTING MEANS AND SAID SECOND SEGMENT BEING SUCH THAT WHEN SAID CUTTING MEANS IS IN A REGISTERED POSITION WITH SAID INDICIA AND AN INDICIUM IS POSITIONED UNDER SAID PHOTOELECTRIC SCANNING MEANS SAID SECOND SEGMENT IS POSITIONED INTERMEDIATE SAID SECOND AND THIRD PAIRS OF BRUSHES; A RELAY INCLUDING A SINGLE POLE DOUBLE THROW SWITCH HAVING A MOVABLE ARM AND A FIRST CONTACT NORMALLY ENGAGED BY SAID ARM AND HAVING A SECOND CONTACT NORMALLY DISENGAGED FROM SAID ARM, SAID RELAY BEING ELECTRICALLY COUPLED TO SAID SCANNING MEANS AND OPERABLE IN RESPONSE THERETO UPON OPERATION OF SAID SCANNING MEANS BY SAID INDICIA TO CAUSE SAID RELAY ARM TO DISENGAGE FROM SAID FIRST CONTACT AND ENGAGE SAID SECOND CONTACT, A HOLDING CIRCUIT MEANS INCLUDING A SOURCE OF ELECTRICAL POWER AND SAID FIRST SWITCH, SAID FIRST SWITCH BEING ARRANGED SO THAT SAID FIRST SWITCH IS CLOSED DURING A PORTION OF THE CYCLE OF SAID CUTTING MEANS WHEN SAID CUTTING MEANS IS ADJACENT ONE OF SAID INDICIA, SAID HOLDING CIRCUIT MEANS BEING OPERABLY CONNECTED TO SAID RELAY TO HOLD SAID ARM IN ENGAGEMENT WITH SAID SECOND CONTACT FOR A PORTION OF THE CYCLE OF SAID CUTTING MEANS, AN ADVANCE CIRCUIT MEANS INCLUDING A SOURCE OF ELECTRICAL POWER AND SAID SECOND SWITCH, SAID SECOND SWITCH BEING ARRANGED SO THAT WHEN SAID CUTTING MEANS IS IN A RETARDED DISPOSITION RELATIVE TO SAID INDICIA SAID SECOND SWITCH IS CLOSED, SAID ADVANCE CIRCUIT BEING CONNECTED TO SAID SECOND CONTACT AND TO SAID CONTROLLER, AND SAID ADVANCE CIRCUIT MEANS BEING ARRANGED SO THAT ENGAGEMENT OF SAID SECOND CONTACT BY SAID ARM AND CLOSURE OF SAID SECOND SWITCH IS EFFECTIVE TO COMPLETE SAID ADVANCE CIRCUIT MEANS AND IMPART A CURRENT TO SAID CONTROLLER TO TURN SAID MOTOR MEANS IN AN ADVANCING DIRECTION AND THROUGH SAID MOTION TRANSMISSION MEANS TO MOVE DIRECTLY SAID CUTTING MEANS BEFORE CUTTING SAID MATERIAL TO A POSITION OF SUBSTANTIALLY EXACT REGISTER WITH SAID INDICIA, A RETARDING CIRCUIT MEANS INCLUDING A SOURCE OF ELECTRICAL POWER AND SAID THIRD SWITCH, SAID THIRD SWITCH BEING ARRANGED SO THAT WHEN SAID CUTTING MEANS IS IN AN ADVANCED POSITION RELATIVE TO SAID INDICIA SAID THIRD SWITCH IS CLOSED, SAID RETARDING CIRCUIT MEANS BEING CONNECTED TO SAID FIRST CONTACT AND TO SAID CONTROLLER, SAID RETARDING CIRCUIT MEANS BEING ARRANGED SO THAT ENGAGEMENT OF SAID FIRST CONTACT BY SAID ARM AND CLOSURE OF SAID THIRD SWITCH IS EFFECTIVE TO COMPLETE SAID THIRD CIRCUIT MEANS AND IMPART A CURRENT TO SAID CONTROLLER TO TURN SAID MOTOR MEANS IN A RETARDING DIRECTION AND THROUGH SAID MOTOR TRANSMISSION MEANS TO MOVE DIRECTLY SAID CUTTING MEANS BEFORE CUTTING SAID MATERIAL TO A POSITION OF SUBSTANTIALLY EXACT REGISTER WITH SAID INDICIA, AND SAID SECOND AND THIRD SWITCHES BEING ARRANGED SO THAT THE SWITCHES ARE OPEN WHEN SAID CUTTING MEANS IS IN REGISTER WITH SAID INDICIA AND AN INDICIUM IS POSITIONED UNDER SAID PHOTOELECTRIC SCANNING MEANS WHEREBY NO CORRECTION IS MADE.
