Dial Telegraph

I think the needle type telegraph preceded the dial telegraph. These were essentially a normal magnetic compass (or it's needle) with a nearby coil that would deflect the needle in one direction or the other. A single needle instrument can have three states, Left, Off or Right.

The idea of the dial telegraph is that the sender uses the transmitter to point to a letter and the receiver points to the same letter. There needs to be some way to synchronize the receiver and transmitter and this was the subject of many stock ticker patents. How did the ABC dial telegraphs handle it? Does a dial telegraph make the characteristic sound of ticking as the receive pointer moves similar to a stock ticker?

I think these were the precursors for the Stock Tickers that added a printed strip of paper to a dial telegraph. The dial versions of the telegraph appeared at the very start of the telegraph industry.
