Abstract
Abstract Paper gripping device for use with a chain driven paper carriage comprising a gripper bar mounted between the driving chains of the paper carriage, the gripper bar having a U-shaped configuration where one leg of the U-shaped bar is stepped at the upper extremity thereof to form an inner, lower step and an outer, higher step; a shaft rotatably mounted in and along the length of the gripper bar; grip members mounted on the shaft; springs for respectively biasing the group members against the lower step of the stepped portion of the gripping bar so that when a paper sheet is gripped by the gripping member an outwardly convex configuration is imparted thereto by the upper step of the stepped portion to thereby facilitate subsequent processing of the paper; and cam means for rotating the grip members away from the lower step against the biasing action of the springs to permit reception or release of the paper away from the paper gripping device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
Paper gripping device for use with a chain driven paper carriage having at least two driving chains comprising a gripper bar mounted between the driving chains of the paper carriage, said gripper bar having a U-shaped configuration where one leg of the U-shaped bar is stepped at the upper extremity thereof to form an inner, lower step and an outer, higher step having a rise therebetween; a shaft rotatably mounted in and along the length of said gripper bar; grip members mounted on said shaft; springs for respectively biasing said grip members against said inner, lower step of the stepped portion of the gripping bar, said grip members engaging said lower step substantially adjacent to the said rise from said inner, lower step to said outer, higher step so that when a paper sheet is gripped by said gripping member an outwardly convex configuration is imparted thereto by the upper step of said stepped portion to thereby facilitate subsequent processing of said paper; and cam means for rotating said grip members away from said lower step against the biasing action of said springs to permit reception or release of said paper away from said paper gripping device.
Claim 2
Dependent Claim
197 words
Paper gripping device for use with a chain driven paper carriage having at least two driving chains comprising a gripper bar mounted between the driving chains of the paper carriage, said gripper bar having a U-shaped configuration where one leg of the U-shaped bar is stepped at the upper extremity thereof to form an inner, lower step and an outer, higher step having a rise therebetween; a shaft rotatably mounted in and along the length of said gripper bar; grip members mounted on said shaft; springs for respectively biasing said grip members against said inner, lower step of the stepped portion of the gripping bar, said grip members engaging said lower step substantially adjacent to the said rise from said inner, lower step to said outer, higher step so that when a paper sheet is gripped by said gripping member an outwardly convex configuration is imparted thereto by the upper step of said stepped portion to thereby facilitate subsequent processing of said paper; and cam means for rotating said grip members away from said lower step against the biasing action of said springs to permit reception or release of said paper away from said paper gripping device.
Claim 3
Dependent Claim
55 words
A paper gripping device as in claim 1 where each of said grip members includes an upper, forwardly extending portion which engages said lower step under the biasing action of its associated spring and a lower, downwardly extending stopper portion against which said paper is registered as it is received by said paper gripping device.
Claim 4
Dependent Claim
71 words
A paper gripping device as in claim 2 including first cam members mounted in alignment with each other along said shaft for respectively raising said grip members away from said lower step; at least one lever mounted on said shaft; and a further cam member disposed adjacent the path traveled by said grip members for rotating said lever to effect said raising of the grip members through said first cam members.
