Model: T06 Approximate Lever Parallel Scale Mechanism of Pfitzer
As in the problem of creating a straight-line motion from linkages as in the Model S series, a related problem is the synthesis of linkages that will maintain parallel orientation between two surfaces. In this model, three lever elements are coupled to approximately maintain parallel orientation between the two horizontal platforms. This device found use in chemical balance scales and weighing machines. The aesthetic eye of Reuleaux is evident in the design of this model by the use of gracefully curved inside connecting links between the upper platforms and the lower levers reminiscent of Chinese characters.
