Trammel of Archimedes
Description
This Mechanism Consists Of A Base With Two Slots Intersecting At Right Angles. Two Sliders Are Confined Within The Slots And Are Attached To A Handle By Pivots (Screws) At Fixed Positions Along The Handle. The Mechanism Can Be Used For Drawing A Perfect Ellipse. This Is Done By Positioning A Writing Utensil At The End Of The Handle While Making A Full Revolution. With That Said, It Is Often Sold In Novelty Shops With Interesting Names Like Bullsh*T Grinder, Bullsh*T Masher Or Do-Nothing Machine. Interestingly, Most Of The Names Are Preceded With State Names Such As Arkansas, Kentucky, Etc. I Guess That’S How Locals Make Fun Of Their Neighbors.
