Tinkertoy

The Tinkertoy Construction Set is a toy construction set for children. It was designed in 1914—six years after the Frank Hornby's Meccano sets—by Charles H. Pajeau, who formed the Toy Tinker Company in Evanston, Illinois to manufacture them. Pajeau, a stonemason, designed the toy after seeing children play with sticks and empty spools of thread. Pajeau partnered with Robert Pettit and Gordon Tinker to market a toy that would allow and inspire children to use their imaginations. After an initially-slow start, over a million were sold. The cornerstone of the set is a wooden spool roughly two inches in diameter, with holes drilled every 45 degrees around the perimeter and one through the center. Unlike the center, the perimeter holes do not go all the way through. With the differing-length sticks, the set was intended to be based on the Pythagorean progressive right triangle. The sets were introduced to the public through displays in and around Chicago which included model Ferris wheels.
