Model: T03 Parallel Guide of Schwilgue
In this model, the horizontal platform is maintained horizontal as the left-hand level is rotated. Such devices were used for weighing mechanisms. This is a compound linkage with ten cylindrical joints and eight links, three of which have three joints not counting the free link and the joint on the left. This complex mechanism consists of two coupled four-bar linkages and has one degree of freedom of motion.
