Marblevator, Mechanisms.

https://www.youtube.com/watch?v=bl2-R0jftvw. "Marblevator, Mechanisms" is the latest addition to my Marblevator series of marble machines, showcasing my fascination with gears, mechanisms, marble machines, and history. This model was inspired by my research into vintage machinery and innovative designs. The model incorporates two antique mechanisms: a "Peaucellier–Lipkin" straight line mechanism (1864) and a "Whitworth" quick return mechanism (1800s). When combined in this design, these mechanisms provide a slow ascent along a straight line and a rapid descent. In this model, I utilize these combined functions to raise a bucket containing an 8mm ball bearing to the top of a built-in track, dump the marble onto the track, rapidly lower the bucket to pick up the marble at the bottom of the track, and repeat the process. I've included a sketch illustrating my method for computing bar lengths in the straight line mechanism. If you have any questions about this illustration, please leave a comment and I'll do my best to answer. As usual, I may have overlooked some files or details, so if you have any questions, don't hesitate to ask – I make mistakes like anyone else.
