  • Selective Motion Transfer Mechanism
    Publication number: 20230296163
    Abstract: A selective motion transfer mechanism acts to transmit rotary motion between a common element and a selected one of multiple channel elements. The common element can be positioned in alignment with any one of the channel elements, and when so aligned, rotation of one of the aligned elements causes rotation of the other.
