Mechanical Signal Generator
Mechanical Signal Generator is constructed from a Tuning Fork and a Sliding Frame.
It represents a very early type of Analog Computer and Graphics Plotter which was used to visualise sine waves. The device consisted of a mahogany base and bridge for two tuning forks. The forks would be held upside down and would would have a pen attached to one prong; this would mark the sliding board when it was released by means of a catch at the back of the frame.
The unit pictured is recorded in the National Inventory of Historic Scientific Instruments by Charles Mollan, entry 1939 UCP 166. The device is known to be fabricated in mid to late 19th Century.
