Newman R. Marshman of New York invented this writing machine around 1901. It was described by the writer of one article as a kindergartner's typewriter, but, to be fair, Marshman himself did always intend for it to be used by children. However, this typewriter was no as a toy, rather a legitimate teaching tool. I am unsure why it had a clock face and if it was functional or not. Marshman would later help develop the Sun Index Typewriter.
