Model: 078 Variable Reciprocating Movement
The combination of gearing in this model produces a variable speed and movement of the lever and arm. Many different combinations are worked out in this manner. A particular use is in textile machinery.
[Virginia Downward & William M. Clark, 1930]

Editor's Note:
This compound mechanism consisting of an elliptically-shaped gear and a lever was copied from the 1868 catalog of Henry T. Brown, page 52, mechanism number 201. FCM
