walking rule or waywiser is a tool commonly used in surveying.
The surveyor pushes it along the ground to measure distances
where laying down a tape would be impractical.

here is a Lufkin Rule Company walking rule model #202. Formerly
the E.T. Lufkin Board and Log Company of Cleveland, Ohio,
the company was bought by a group of investors and relocated
to Saginaw, Michigan, in 1885. It operated continuously until
1967, at which time Cooper Industries Inc. bought the company
and sold a line of products under the Lufkin brand name until
the late 1990s.
