Charles Marshall Gravatt, of Asheville, North Carolina (1932)
Pure Mechanical (PM)
Double Shuffle, 1932
Mechanical flippers (8). Each of two levers control four flippers simultaneously.
According to the Encyclopedia of Pinball Volume 1, this game was not immediately patented so another company made it as Western Mfg.'s 1932 'Shuffle Ball' and advertised it as having eliminated the plunger, among other changes. Gravatt's game never had a plunger so that comment appears to have been a comparison to previous pinball games.
After six months of manufacture and operation in North Carolina, Charles Chizewer, President of Hercules Novelty Company, convinced Charles Gravatt to apply for a patent to protect his rights to this game.
