A Geneva drive mechanism for intermittently and selectively rotating one or more drive shafts through indexed positions. A conventional Geneva mechanism is modified to include a drive movable between a non-driving and driving position. When the driver is in its non-driving position, a plurality of Geneva wheels is secured against rotation. When the driver is moved to its driving position, it engages a selected Geneva wheel and rotates the wheel through one indexed position. Meanwhile, any other Geneva wheels remain secured against rotation. A compact gear mechanism is disclosed for coupling the Geneva mechanism and drive motor to a pair of coaxially mounted shafts. |
