Image telegraph
Bakewell's "image telegraph" had many of the features of modern facsimile machines, and replaced the pendulums of Bain's system with synchronized rotating cylinders.
The system involved writing or drawing on a piece of metal foil with a special insulating ink; the foil was then wrapped around a cylinder which slowly rotated, driven by a clock mechanism. A metal stylus driven by a screw thread traveled across the surface of the cylinder as it turned, tracing out a path over the foil. Each time the stylus crossed the insulating ink, the current

through the foil to the stylus was interrupted. At the receiver, a similar pendulum-driven stylus marked chemically treated paper with an electric current as the receiving cylinder rotated.
The chief problems with Bakewell's machine were how to keep the two cylinders synchronized and to make sure that the transmitting and receiving styli started at the same point on the cylinder at the same time. Despite these problems, Bakewell's machine was capable of transmitting handwriting and simple line drawings along telegraph wires. The system, however, never became commercial.
Later, in 1861, the system was improved by an Italian priest, Giovanni Caselli
