Hand Power Test Arcade Game
"Drop in a Nickel, Only" and "Try Your Grip" with this "Hand Power Test" coin-operated arcade game. How cool, right?! This strength tester was invented by Joseph DeVantery of Brooklyn, New York. He patented it as the "Coin Controlled Strength Testing Machine" under patent no.385,921 which was issued on July 10, 1888 and assigned to the Hand Power Test Company, also of New York.
I would be interested in this or any other early strength test machines.
