Phantoscope, 1904-1905, made by C. Francis Jenkins in Washington DC

“My own contribution to this line was a Phantoscope toy (U.S. Patent No. 779,364, 1905) in which a flexible band was employed, the card being attached thereto by their lower ends and having a spaced relation of about five thousands inch. This close spacing of the cards assured a firm adhesion to the band and to each other.” C, Francis Jenkins, in the October 1920 in the Transactions of the SMPE journal.

We have a date of 1904 for the patent application and a date of 1905 for the granting of the patent.
