Royal
Electric Braille Ticker Machine
ca. 1930s - page 1
Pictured here are the 3 components of the machine. At the left is the ticker tape printer component and in the middle is a manual Royal typewriter. The silver box on the right is a vented box which contains a dozen vacuum tubes. Both the ticker machine and the manual typewriter have electrical wires that lead back to the aluminum power source box. A second wiring interface runs from under the typewriter to ticker. I can only assume that what was typed on the typewriter was transmitted to the ticker machine and printed. I believe that it is possible that this is a demonstration machine that produced electronic braille.
This is a closer view of the ticker printer portion of the device and next to the typewriter you can see the interface cable between the 2 components.
Side view of the ticker printer. Stock ticker machines are an ancestor of the modern computer printer, being one of the first applications of transmitting text over a wire to a printing device.
The underside of the vacuum tube box showing all the hand soldered connections of the tubes. It is my guess that the box functioned as a voltage regulator.
The marked area shows a 3 by 2 configuration of what appears to be pins or bars. Which would confirm the conclusion that this contraption converted manual typing automatically to braille.
