Abstract
A clothespin-like gripper having a pair of clamp jaw portions resiliently urged together and adapted to embrace and thereby grip a magnetic diskette or disk-jacket assembly for pulling the diskette from an original position into a final position. A swingable blocker is provided on the gripper so that the diskette is thereby blocked from being embraced by the gripper whereby the gripper may be used to move the diskette back from its final position into its original position without any embracing action by the gripper.

6. Mechanism for gripping an article and moving it in a first direction from an original position to a final position and then back from said final position to its said original position in a second opposite direction and including:
-
a gripper having a pair of clamp jaw portions movable toward and away from each other and resilient means urging said jaw portions together whereby they may be moved onto the article to embrace and frictionally grip the article between them, means for moving said gripper in said first direction whereby the gripper is effective to pull the article from its original position to its final position and said means also being operative to move said gripper in the second opposite direction, a blocker carried by said gripper and having two positions in one of which it blocks entry of the article into the gripper and in the other of which it allows entry of the article into the gripper, and a fixed abutment for moving said blocker from its unblocking position to its blocking position on a continued movement of said gripper in said first direction subsequent to a movement by said gripper of the article into its final position whereby the blocker may be effective to abut said article and move the article back from its final position toward its original position on a movement of said gripper in the second opposite direction. - View Dependent Claims (7)

8. In a method for moving an article in a first direction from an original position to a final position and then back from said final position to its said original position in a second opposite direction including the steps of:
-
utilizing a gripper including a pair of clamp jaw portions resiliently urged together and having outwardly diverging cam surfaces on adjacent ends of the two jaw portions to define a throat and moving the gripper in said second direction toward said article in its original position so that said jaw portions cam over an edge of the article and embrace and frictionally grip the article, then moving said gripper in said first direction so that said gripper pulls the article into its said final position, continuing the movement of said gripper in said first direction while holding the article from further movement in this direction out of its said final position so as to strip said gripper from the article, moving a blocker across said throat of said gripper, and then moving said gripper with said blocker across its said throat in said second direction so that the blocker abuts the article and moves the article from its said final position back to its said original position while blocking entrance of the article into said gripper. - View Dependent Claims (9)
