Abstract
A pilgrim step indexing mechanism provided with oppositely facing toothed ratchet wheels of the same pitch is associated with a single indexing pawl and an associated detent spring which not only detentably holds the ratchet wheels but also biases the indexing pawl to engage the ratchet wheels. The indexing pawl has two teeth one of which engages one of the ratchet wheels during a reverse stroke of the pawl to reverse feed both ratchets one increment and during a forward stroke of the pawl to advance both ratchets two increments. The ratchet wheels may be connected with a platen of a printer whereby a line of printwork, after printing, will be positioned two line spaces above the printing line for easy viewing.
