Apparatus for feeding continuous webs of stationery

Claim 1

APPARATUS FOR FEEDING CONTINUOUS STATIONERY AROUND THE PLATEN OF A PRINTING MECHANISM, COMPRISING: PIN FEED MECHANISM FOR FEEDING THE CONTINUOUS STATIONERY, AN ENDLESS BELT, MEANS FOR FEEDING SAID ENDLESS BELT IN SYNCHRONISM WITH THE CONTINUOUS STATIONERY AND THROUGH ONE COMPLETE CIRCUIT EACH TIME A PREDETERMINED LENGTH OF THE CONTINUOUS STATIONERY IS FED, THE SAID ENDLESS BELT HAVING INDICIA TO CORRESPOND TO PREDETERMINED POSITIONS ON THE CONTINUOUS STATIONERY, ELECTRIC ROTARY SOLENOID MEANS MOVABLE THROUGH AN ACCURATELY PREDETERMINED RANGE OF ACTUATING MOVEMENT DURING EACH ENERGIZATION AND SPRING RETRACTED TO A PREDETERMINED STARTING POINT UPON DE-ENERGIZATION, MANUALLY CONTROLLABLE SWITCH MEANS FOR EFFECTING ENERGIZATION OF SAID ELECTRIC ROTARY SOLENOID MEANS, IN SAID RANGE OF ACTUATING MOVEMENT CORRESPONDING TO A SINGLE INCREMENT OF FEEDING MOVEMENT OF THE STATIONERY, SAID FEEDING MEANS COMPRISING A UNIDIRECTIONAL DRIVING COUPLING BETWEEN SAID ELECTRIC ROTARY SOLENOID MEANS AND THE PIN FEED MECHANISM FOR OPERATING SAID PIN FEED MECHANISM TO FEED THE CONTINUOUS STATIONERY ONE INCREMENT EACH TIME THE ELECTRIC ROTARY SOLENOID MEANS IS ENERGIZED, SAID COUPLING BEING INOPERATIVE ON RETRACTION MOVEMENT OF SAID ELECTRIC ROTARY SOLENOID MEANS, A SWITCH IN CIRCUIT WITH SAID ELECTRIC ROTARY SOLENOID MEANS, MEANS CARRIED BY THE ELECTRIC ROTARY SOLENOID MEANS FOR ENGAGING AND OPENING SAID SWITCH AT THE CONCLUSION OF EACH ACTUATING MOVEMENT OF SAID ELECTRIC ROTARY SOLENOID MEANS FOR DE-ENERGIZING SAID ELECTRIC ROTARY SOLENOID MEANS, CARRIAGE CONTROL CONTACTS IN CIRCUIT WITH SAID ELECTRIC ROTARY SOLENOID MEANS FOR CONTROLLING THE ENERGIZING OF SAID ELECTRIC ROTARY SOLENOID MEANS, SAID MANUALLY CONTROLLABLE SWITCH MEANS BEING IN CIRCUIT WITH THE ELECTRIC SOLENOID MEANS INDEPENDENTLY OF THE SAID CARRIAGE CONTROL CONTACTS AND OPERABLE WHEN CLOSED TO NULLIFY THE CONTROLLING ACTION OF SAID CARRIAGE CONTROL CONTACTS, SENSING MEANS COOPERATING WITH SAID ENDLESS BELT AND ACTUATED BY THE INDICIA THEREON, AND RELAY MEANS CONTROLLED BY SAID SENSING MEANS AND OPERATIVE IN RESPONSE TO ACTUATION OF SAID SENSING MEANS FOR DISRUPTING THE CIRCUIT BETWEEN SAID ELECTRIC ROTARY SOLENOID MEANS AND SAID MANUALLY CONTROLLABLE SWITCH MEANS.
