WHY IT’S INTERESTING
An incomplete telegraph register with automatic speed regulator. At the side of the machine is a toothed wheel attached to one of the rollers in the drive train and engaging a worm gear at the upper end of a revolving rod, to the lower end of which are attachments which formerly had two adjustable fans. The fans were made to open and close automatically and control the speed of the machine. Willia
