Cottle Windmill, Patent Model

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to J. and F. M. Cottle, October 21, 1879, no. 220751.
This mill has a double-rimmed steel wind wheel made up of small wedge-shaped vanes, which are removable to permit regulation of the power of the mill. The wind wheel cannot be swung out of its position, but the shaft is carried in sliding bearings so that the gear on the shaft can be disengaged to let the wheel run free. It is equipped with a selective gear transmission. The model shows the mill attached to the bucket chain of a well.
