Typewriting on the Sky
Type of Work
From the article, which was published in The Literary Digest:
A TYPE WRITER has been invented that prints its letters against the sky in lines of flame, as well as writing them on paper in the usual way. The keys are electrically connected with a system of lamps held aloft by a massive framework. Says a descriptive writer in The Scientific American:
"News bulletins, flashed in big electric letters almost simultaneously with their receipt over press-wires, are made possible by a new electrical device. This invention consists of a huge bulletin-board, operated by a typewriter. It is called an electrograph.
