James Chesterman and the Measuring Tape
Any carpenter will tell you that measuring tape is one of the indispensable tools of the trade, but do you know anything about the man who developed flexible steel, the thing that makes this invention possible? James Chesterman was born in London on September 15, 1792, and died in Sheffield, England, at the age of 74 on April 25, 1867.
In 1821, we know that Chesterman received a British patent for a device that used a spring to rewind measuring tapes automatically. In 1842, over 20 years later, he and James Bottom patented a tape made of woven cloth that used wire strands. His process for heat treating long strips of steel, patented in 1853, led to the making of steel tapes, a type of measure which didn’t change for 50 years.
Scientific American referred to Chesterman & Co. in 1869, just a few years before his death, as “about the most unique thing of the kind we have ever seen,” and then discussed its neatness, its compactness (and thus, portability), as well as its capability to measure things precisely. W & LE Gurley offered to the public Chesterman steel tapes beginning in 1871, and described them as thin ribbons of steel with joints at intervals that were wound up in a leather case, that had a folding handle. They were marketed for 17 dollars, but in those years that would be equivalent to selling tape measures at 300 dollars apiece. For that reason, they were not in use among the general public. However, Gurley sold a less costly version, one of cloth reinforced with wire, for about five dollars and 25 cents.
