Until Henry Van Hoevenbergh came up with his unison device, runners had to hand-reset these devices.  The "cotton instrument" was a prototype for one of these devices made by a man whose first 40 patents concerned them, including one for a screw-thread unison to keep them in sync.  F. L. Pope helped S. S. Laws develop one of the first versions of these machines in 1867 that was originally only used in the gold industry.  The last of these to be mass-produced was made by the (*) New York Quotation Company.  A "universal" one of these devices was the first commercial success for a young Thomas Edison and was manufactured by Western Electric.  The dedication of the Statue of Liberty was the first time the output of these devices was thrown out the window in celebration.
