Abstract
Abstract A device for transmitting accurate translational and rotary movements includes a rotary input shaft on which is mounted a rotary driving cam which is engaged with a pivotal follower carried on a first lever member intermediate its length. The first lever member is pivoted at its lower end in the housing containing the cam, and its upper end is engaged with the output shaft. The output shaft is guided in rotary roller bearings and linear ball bearings and it is shifted laterally, backwardly, and forwardly by pivotal movement of the first lever as its follower rides in the cam. A second gear control lever is pivotally mounted in the housing to extend transversely in respect to the first lever and it includes a follower which is also engaged in a groove of the cam and this causes the pivotal movement of the second lever. The outer end of the second lever is pivotally connected to a connecting rod which in turn is connected to a gear member in the form of a quadrant through a universal joint connection. The gear member or quadrant meshes with a gear carried on the output shaft to rotate the output shaft. Meshing engagement is only effective when the output shaft moves a predetermined distance transversely so that meshing engagement with the quadrant can be easily effected.
