Erector Set
Ives' train sales continued to decline in the face of increasing competition and Lionel's greater momentum, the latter having released its first electric trains nearly a decade earlier. Meanwhile, construction toys were gaining in popularity, so in an effort to re-diversify, Ives released a Meccano and Erector Set-like construction toy in 1913 named Struktiron. Although it offered parts its competition did not, the set was not very successful and Ives withdrew it from the market in 1917.
