American Iron, Steel, and Brass Wheel Cutting Engine

The iron-framed crank-driven engine is mounted to a wood base, 11 1/2 in. punched brass dividing plate with nine divisions, straight steel indexing arm, and wood handles.

This tool is discussed and illustrated in T. R. Crom, Horological Shop Tools 1700–1900, p. 665, fig. 1293, stating that it was found in a Connecticut attic. It is interesting to note a similar machine used by the Dominy clock makers in East Hampton, New York.
