Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
In a newspaper stuffing machine where a newspaper section is opened at a stuffing station so it may be stuffed with insert material, the newspaper being fed from a jacket supply hopper to a transport conveyor moving past the stuffing station which is located in front of a gathering conveyor on which is gathered the insert material to be stuffed, and in which the insert material may be composed of a number of individuual inserts fed to the gathering conveyor from a corresponding number of insert supply hoppers disposed in feeding relation to the gathering conveyor: means to feed the newspaper sections one by one from the jacket supply hopper to the transport conveyor; a detector to detect failure to feed a newspaper section timely to the stuffing station; a reject deflector positioned at the stuffing station normally to support and guide the gathered insert material for delivery into the opened newspaper section and when actuated serving to guide the gathered insert material into a discard station; and means to actuate the reject deflector in the event of failure to detect a timely fed newspaper section thereby to prevent delivery of the insert material intended for the missing newspaper section.
Claim 2
Dependent Claim
200 words
In a newspaper stuffing machine where a newspaper section is opened at a stuffing station so it may be stuffed with insert material, the newspaper being fed from a jacket supply hopper to a transport conveyor moving past the stuffing station which is located in front of a gathering conveyor on which is gathered the insert material to be stuffed, and in which the insert material may be composed of a number of individuual inserts fed to the gathering conveyor from a corresponding number of insert supply hoppers disposed in feeding relation to the gathering conveyor: means to feed the newspaper sections one by one from the jacket supply hopper to the transport conveyor; a detector to detect failure to feed a newspaper section timely to the stuffing station; a reject deflector positioned at the stuffing station normally to support and guide the gathered insert material for delivery into the opened newspaper section and when actuated serving to guide the gathered insert material into a discard station; and means to actuate the reject deflector in the event of failure to detect a timely fed newspaper section thereby to prevent delivery of the insert material intended for the missing newspaper section.
Claim 3
Dependent Claim
67 words
A machine according to claim 1 wherein the transport conveyor delivers the stuffed newspaper section to a collecting station, detectors to detect the delivery of each insert to the gathering conveyor, a second reject deflector interposed between the transport conveyor and the collecting station, and means to actuate the second reject deflector when the insert material is insufficient in number, thereby to reject the corresponding newspaper section.
Claim 4
Dependent Claim
127 words
A machine according to claim 2 in which the deflector to reject the inserts and the second deflector to reject the newspaper section are each in the form of a guide plate spring biased to normal position respectively to guide the inserts to the stuffing station and to guide the newspaper section to the collecting station, a first solenoid which when energized actuates the first-named deflector to reject the inserts, a second solenoid which when energized actuates the second-named deflector to reject the newspaper section, a circuit to energize the first solenoid upon failure of a newspaper section timely to arrive at the stuffing station, and a circuit to energize the second solenoid when there is failure to detect delivery of an insert to the gathering conveyor.
Claim 5
Dependent Claim
55 words
A machine according to claim 1 in which the reject deflector is a pivotally mounted guide plate spring biased to normal position to guide the gathered inserts to the stuffing station, a solenoid connected to the plate to actuate the plate to reject position, and a circuit controlled by the detector to energize the solenoid.
Claim 6
Dependent Claim
30 words
A machine according to claim 1 including means to detect failure to feed an insert from a hopper and means to reject the newspaper section downstream of the stuffing station.
