Marblevator, Mechanisms.

youmagine

"Marblevator, Mechanisms" is the latest marble machine I've created, featuring the fastest lift mechanism I've ever designed. My passion for gears, mechanisms, marble machines, and history drives my inspiration for each new model. This one was no exception. The model showcases two antique mechanisms: a "Peaucellier-Lipkin" straight line mechanism from 1864, and a "Whitworth" quick return mechanism from the 1800s. When combined, these mechanisms provide a slow ascent along a straight line and a rapid descent. In this design, I've utilized these functions to slowly lift a bucket containing an 8mm ball bearing to the top of a short track, dump it onto the track, rapidly lower the bucket to pick up the marble at the bottom, and repeat the process. A sketch illustrates how I calculated the bar lengths for the straight line mechanism. If you have any questions about the illustration, feel free to ask in the comments – I'll do my best to answer. As usual, I may have forgotten a file or two, so don't hesitate to reach out if you have any questions. I make mistakes, and I'm always happy to clarify anything.
