Motion Transmitting Linkage

The motion transmitting linkage permits adjustments in the extent of movement of the driven output member without changing the input motion imparted to the linkage.

The input motion is provided by rotatable cam 10 which is engaged by can follower 11 mounted on the end of lever 12. The latter is pivoted intermediate its ends by relatively stationarily mounted pivot pin 13 while the other end of lever 10 carries pin 14. Rotatably supported on pin 14 is collar 15 and rigidly attached to this collar are oppositely directed follower lever 16 and output lever 17. Spring 18, connected to lever 17, biases the lever 16 into engagement with mounting collar 19 carried by lever 12 and journaled on pin 13.

Cam 10 is rotated and lever 17 moves to the extent indicated in the upper right drawing when cam follower 11 moves from the high to the low dwell of the cam. The clockwise movement of lever 12 causes pin 14 to move in an arc to the left. The engagement of lever 16 with the relatively stationary collar 19 during the movement of lever 10 permits lever 17 to move to the left under the action of spring 18. To change the extent of the movement of lever 17, latch 21 is operatively positioned so that it engages the extreme upper end of lever 16 after it moves to the right to a selected extent as in the lower drawing. This limits the movement of lever 17 without requiring alteration of the input movement. The position of latch 21 relative to the path of...
