Abstract
Abstract A rigid, linear rod having an integral slideway having opposed, open-ended grooves in which scales are interchangeably inserted longitudinally into the grooves. Tips on the end of the rod hold individual tapes with scales thereon, against longitudinal shifting. The tapes are resilient, and are resiliently secured in the slideway grooves. The tips are removable and replaceable so that different scales can be interchangeably mounted on the rod. The construction allows mass construction since the same type rods can be provided with different scales which are graduated differently.
