Dog-Powered Treadmill, Patent Office

Description
This model was submitted to the U.S. Patent Office with the application for the patent issued to F. K. Traxler, April 23, 1878, no. 202679.
The treadmill represented consists of an endless track of wooden cleats on a flexible belt, carried over two rollers held in a rigid frame. The frame pivots about the shaft of the upper roller so that the lower end of the frame may be raised or lowered to give any desired angle of inclination to the track. A power take-off is geared to the shaft of the upper track roller.
