Miller Mercury Motor, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to Thomas Davidson Miller, of Pittsburgh, Pennsylvania, November 6, 1877, no. 196759.
The model represents a boiler, condenser, and an overshot wheel connected with suitable piping so that mercury placed in the boiler will be sublimated there and the fumes will rise to the condenser where they will be condensed. From the condenser the liquid mercury runs over the buckets of the wheel where the weight of the mercury is employed in turning the wheel. Suitable sheathing about the wheel collects the mercury and returns it to the boiler, which it enters by reason of its weight.
