Rulers and Tape Measures

Daniel Morales

On July 14, 1868, the design of a spring measuring tape in a circular case was patented by Alvin J. Fellows of new homed. This was the first United States patent for a spring tape measure but Fellows’ patent was actually just for an improvement to an earlier design. The original invention was English and Fellows’ improvement to it was a new way to attach the spring clip, allowing the tape to be locked in any position until the clip was released. Because it was expensive, this type of measuring tape did not immediately replace folding wooden rulers but it was the basis for the locking steel tape measures used today.

What a Tape Measure Does

A tape measure is a portable measurement device used to quantify the size of an object or the distance between objects. The tape is marked along the tape edge in inches and fractional inches, typically in quarter-, eight-, sixteenth-inch increments. Some tape measures are marked in millimeters, centimeters, and meters on one edge.
