a crude thing made of a wooden stand, a funnel, a cup of acid, and some copper wire - what was it?
not a battery,not electro plating, something to catch the resulting
element from the reaction of acid and copper?

A fax machine from the year 1865
The idea of putting the achievements of telegraphy to good use in order to transmit photographs as well as printed texts and drawings dates back to the 1850's. The Pantelegraph conceived by the abbot, Giovanni Caselli, was a system of sending and receiving images over long distances by means of electrochemistry.
The stylus of the transmitter scanning an original document by moving across its parallel lines sent messages by telegraph to a receiver. The stylus of the receiver moving across a chemically-treated sheet of paper reproduced the document according to the signals received. Transmitter and receiver were syncronized by two large pendulums swinging in sync with each other. On 16th February, 1865 the Pantelegraph was introduced into service for the Paris and Lyons and the Paris and Le Havre on to the Marseille Railways. It was phased out in 1870. The machine on display in the Museum is a working model that was built for the 1932 Chicago Exhibition.
