Abstract: The Geneva mechanism converts continuous rotation into intervals of rotary motion. The drive wheel of the Geneva mechanism is fitted with a pin which rotates and moves the driven wheel in an intermittent manner. A circular disc on the drive wheel locks the driven wheel in place between each rotation. The Geneva drive design features four slots on the client wheel, which advances the drive one step at a time for every full revolution of the master wheel. If the steering wheel has n number of slots, it advances by 360°/n for each complete rotation of the propeller wheel. This mechanism employs two shafts, one of which is driven and the other is driving. The driven shaft has radial slots in which the pin can contact. The pin enters one of the slots and, when the driver is rotated further, it drives into the slot and rotates the follower. This mechanism has several advantages, including the fact that it is the simplest and least expensive of all intermittent motion mechanisms, and that it can be built in a number of sizes depending on the application.
