Model: T14 Parallel Guide for Paddle Wheel Mechanism
This fascinating model has three rotating arms each of which is a four bar linkage that holds paddles in the vertical position as the links rotate. It is thus a parallel guide mechanism. This looks like a mechanism that would have been used for paddle wheel ships or other water wheel applications. See also the Models U1 and U2 which are similar to T14.
