Individually Adjustable Control Arm Fingers

Input control arms 1 for operating translating slides 2 are individually adjustable by separate fingers 3 to compensate for tolerance deviation in the control arm positioning mechanism.

Control arms 1 are normally held in the positions shown against individual bias springs 4 by latch arms 5 and cyclically movable bail bracket 6. Cam 7 permits bail bracket 6 to rotate counterclockwise each cycle. Any arms 1 that have been released by their latch arms 5 rotate with bracket 6 to move an associated slide 2 to the left. Arms 1 are restored to their original position by return clockwise movement of bail bracket 6.

The home position of arms 1 is adjusted by loosening clamping screw 8. This permits adjusting fingers 3 to move freely against wedge camming surface 9 of their associated arms 1 under the influence of individual adjusting springs 10. A setup pin 11 is inserted in gage holes 12 of slides 2 to establish their correct home position. Any slack between bail 6 and slides 2, when in their respective home positions, is thus taken up by rotation of individual fingers 3 against associated camming surfaces 9. The fingers 3 are then clamped as a group to bail 6 by screw 8.
