Often interesting movements can be made by mixing together two or more mechanisms. In this experimental mechanism, I’ve added together a Geneva drive, which produces intermittent rotary motion, with a scotch yoke which converts the rotary motion into up and down motion.
The Geneva drive is a six step wheel, it takes six turns of the drive wheel to turn the Geneva wheel once.
The scotch yoke is connected to the Geneva wheel via a crank. This lifts the vertical shaft up, up, up then down, down, down.
Next step, I’ll complete the parts layout and release this as an Essential Mechanism. I’m also planning on sketching some ideas of how it could be used.
