![]() It was Farrand's concave-convex tape that went on to become the standard for the majority of pocket tape measure tapes today. Their product was later sold to Stanley Works. It is there Farrand and William Wentworth Brown began mass-producing the tape measure. Between 1922 and December 1926, Farrand experimented with the help of The Brown Company in Berlin, New Hampshire. Farrand received patent #1,402,589 for his concave-convex tape, a major improvement for spring pocket tape measures. (The "electric" part of the name was purely an affectation there was nothing electrical about it.) This feature was never patented, but Justus Roe and Sons produced tape measures, "Roe Electric Reel Tape Measures", with this feature during the 1890s and early 1900s when they started etching or stamping increments and numbers on the tapes. A small brass tag, marked with a number indicating the number of feet to that point, was attached every five feet. They were attached every inch in the first and last foot and every foot from one to the end of the last foot. Later, by the early 1870s, Justus Roe of Patchogue, New York added rivets attaching small brass washers to the tape to mark inches and feet. The measured length was marked on the case or crank. It accurately measured only a distance equal to the total length of the tape from beginning to end marker, a brass piece attached to the tape at a measured distance. Paine of Sheboygan, Wisconsin, and produced by George M. patent #29,096 issued 10 July 1860 to William H. The first patented long tape measure in the United States was granted U.S. The tape could be returned to the case by sliding a button on the side of the case which then allowed the spring to pull the tape back into the case. The tape could be stopped at any point and held by the mechanism. Bang's rule was the first attempt in the United States to make a spring return pocket tape measure. On 6 December 1864 patent #45,372 was issued to William H. The first record of people using a measuring device was by the Romans using marked strips of leather, but this was more like a regular ruler than a tape measure. The self-marking tape measure allows the user an accurate one hand measure. A tape measure of 25 or even 100 feet can wind into a relatively small container. The tang is connected to the tape with loose rivets through oval holes, and can move a distance equal to its thickness, to provide both inside and outside measurements that are accurate. This type of tape measure will have a floating tang or hook on the end to aid measuring. Measuring tapes designed for carpentry or construction often use a stiff, curved metallic ribbon that can remain stiff and straight when extended, but retracts into a coil for convenient storage. Today, measuring tapes made for sewing are made of fiberglass, which does not tear or stretch as easily. These types of tape measures were mainly used for the measuring of the subject's waist line. Tape measures that were intended for use in tailoring or dressmaking were made from flexible cloth or plastic. ![]() Tapes may have different scales, be made of different materials, and be of different lengths depending on the intended use. Tape measures are often designed for specific uses or trades. ![]() ![]() Long tapes, instead of being returned by a spring, were usually returned by hand crank. Surveyors also used 49 + 1⁄ 2 feet of a 50-foot tape for 3 rods and 99 feet of a 100-foot tape measure for 6 rods. Because surveying was usually done in rods, surveyors use long tapes of 33 feet (2 rods), and 66 feet (4 rods). These are cased tape measures with tapes of 25, 50, 75, 100, 200, 300, 400, 500, an even 700 feet in length! It is designed for engineers and builders. Pocket tape measures have a tape 1 to 15 feet (0.30 to 4.57 m) in length and 1⁄ 4 to 3⁄ 4 inch (6.4 to 19.1 mm) across.Ī second tape measure design is what is called the long tape. The tape is returned to the case by a spring mechanism. They are small the case is up to about three inches across. Spring return pocket tape measures will generally fit in a pocket. There are two basic types of tape measures with cases: spring return pocket tape measures and long tape measures. Surveyors use tape measures in lengths of over 100 m. Today it is ubiquitous, even appearing in miniature form as a keychain fob, or novelty item. Its design allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. It consists of a ribbon of cloth, plastic, fibre glass, or metal strip with linear measurement markings.
