Abstract
Abstract A device for opening newspapers located within individual pockets (24) of an endless conveyor for receiving inner sections. The folded edge of the newspapers (38) are located at the bottom of the pockets formed by first and second panel members (34, 36) directed upwardly and away from one another defining pockets of a generally V-shaped configuration. A cam controlled plate member (40) pivotably mounted on the first panel member is effective in moving the cut edges to a vertical position against the second panel member (36). A pair of opposed levers (98, 100) having vacuum controlled suction cups (102,104) on their free ends are pivoted to engage the outer surface of the paper adjacent its fold and as they are pivoted outwardly form a center opening (74) at the fold. An opener arm (106) is then pivoted into the opening and upwardly and is effective in holding one half of the paper against the second panel (36) while the other half drops back into engagement with the first panel (34).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A method of opening folded newspapers for a stuffer that are individually deposited into separate conveyor receptacles of the type having first and second cooperating panel members defining a pocket with a generally V-shaped cross sectional configuration, which includes the steps of: (a) moving the opposed groups of cut edges of a folded newspaper from contact with the first panel member into contact with the second panel member; (b) separating the opposed groups to form a center opening in the newspaper adjacent its folded edge; (c) pivoting a separator arm into said center opening for engaging and holding one of the groups of cut edges in contact with the second panel; and (d) returning the other group of cut edges into contact with the first panel member.
Claim 2
Independent Claim
127 words
A method of opening folded newspapers for a stuffer that are individually deposited into separate conveyor receptacles of the type having first and second cooperating panel members defining a pocket with a generally V-shaped cross sectional configuration, which includes the steps of: (a) moving the opposed groups of cut edges of a folded newspaper from contact with the first panel member into contact with the second panel member; (b) separating the opposed groups to form a center opening in the newspaper adjacent its folded edge; (c) pivoting a separator arm into said center opening for engaging and holding one of the groups of cut edges in contact with the second panel; and (d) returning the other group of cut edges into contact with the first panel member.
Claim 3
Dependent Claim
64 words
The method as claimed in claim 1, wherein the step of moving the opposed groups of cut edges includes: (a) applying a cam controlled plate member to the exterior of the folded newspaper; (b) pivoting the plate to move the folded newspaper from an inclined to a vertically extending position; and (c) returning the plate to its initial position while pivoting said separator arm.
Claim 4
Dependent Claim
56 words
The method as claimed in claim 1, wherein the step of separating the opposed groups includes: (a) applying vacuum gripping members to the exterior of the folded newspaper; (b) pivoting the vacuum gripping members away from each other to form said center opening; and (c) discontinuing activation of said gripping members while pivoting said separator arm.
Claim 5
Dependent Claim
39 words
The method as claimed in claim 1, wherein the steps of pivoting a separator arm includes the step of camming a rack gear downwardly to effect rotation of a pinion operatively connected to one end of said separator arm.
Claim 6
Independent Claim
142 words
A device for opening folded newspapers for a stuffer that are individually deposited into separate conveyor receptacles of the type having first and second cooperating panel members defining a pocket with a generally V-shaped cross sectional configuration, said device comprising: (a) means supported on the first panel member for moving opposed groups of cut edges of a folded, newspaper therefrom into contact with the second panel member; (b) means operatively associated with the bottom of each pocket for separating the opposed groups of cut edges to define a center opening in the newspaper adjacent its folded edge; and (c) means pivotably mounted adjacent the side of the panel members for entering said center opening to engage and hold one group of cut edges in contact with the second of said panel members while the other returns to engage said first panel member.
Claim 7
Independent Claim
142 words
A device for opening folded newspapers for a stuffer that are individually deposited into separate conveyor receptacles of the type having first and second cooperating panel members defining a pocket with a generally V-shaped cross sectional configuration, said device comprising: (a) means supported on the first panel member for moving opposed groups of cut edges of a folded, newspaper therefrom into contact with the second panel member; (b) means operatively associated with the bottom of each pocket for separating the opposed groups of cut edges to define a center opening in the newspaper adjacent its folded edge; and (c) means pivotably mounted adjacent the side of the panel members for entering said center opening to engage and hold one group of cut edges in contact with the second of said panel members while the other returns to engage said first panel member.
Claim 8
Dependent Claim
52 words
The structure according to claim 5, wherein said moving means includes: (a) a plate member pivotably attached to the first panel member within the pocket; and (b) a cam controlled follower member operatively connected to said plate member for pivoting the latter toward and away from the second panel member as required.
Claim 9
Dependent Claim
57 words
The structure according to claim 6, wherein said moving means further includes: (a) a horizontal shaft rotatably mounted on the first panel member in operative association with said cam controlled follower; and (b) a pair of upwardly extending arms having first ends fixed on said horizontal shaft and the opposite ends pivotably connected to said plate member.
Claim 10
Dependent Claim
81 words
The structure according to claim 5, wherein said separating means includes: (a) a cam controlled follower member pivotably attached to the pocket; (b) a drive gear attached to one end of said follower member; (c) a pair of opposed gear controlled lever members operatively connected to said drive gear; and (d) vacuum controlled suction cups fixed on the free ends of said lever members for movement therewith to and from contact with the newspaper within the pocket by said drive gear.
Claim 11
Dependent Claim
32 words
The structure according to claim 8, wherein said lever members each include a gear pinion attached to one end thereof with one in meshing relation with the other and said drive gear.
Claim 12
Dependent Claim
40 words
The structure according to claim 5, wherein said entering means defines an opener arm having a drive means operatively connected therewith for pivoting said opener arm to and from a position for holding a newspaper open to receive inner sections.
Claim 13
Dependent Claim
89 words
The structure according to claim 10, wherein said drive means includes: (a) a support shaft for rotatably supporting said opener arm; (b) a rack and pinion gear combination operatively connected to said support shaft; (c) means defining a cam engaging follower mounted on said rack for preventing movement of the latter and rotation of said support shaft; and (d) means for moving said rack and pinion to effect rotation of said support shaft and actuation of said opener arm upon lack of cam engagement by said cam engaging follower.
Claim 14
Dependent Claim
19 words
The structure according to claim 11, wherein said moving means defines a spring member for moving said rack longitudinally.
