Have you ever wondered how a tape measure retracts? Find the answer here…
How Does a Tape Measure Work? - Tape measures are a useful device for any sort of craft, whether it be tailoring or woodworking The first U.S. patent for this commonplace tool was filed in the middle of the 19th century. Now, it would be difficult to imagine a tool box that does not include a retractable tape measure. People who work with tools prefer the retractable tape measure, which brings the measuring tape back into its casing when the measuring process is finished. These handy devices can be sources of wonder in addition to being useful tools. They operate through using spring technology.
How the Tape Measure Retracts - A spring on the inside of the casing supplies all the power that these devices need. When the tape is pulled, the spring inside the casing is extended. Pulling out the end of the tape measure further causes the spring inside the casing to extend. When the user releases the end of the tape measure, it retracts into the unit, and the spring returns to its original position. Most retractable tape measures used in woodworking or construction projects have a switch on the front side. A few retractable tape measures used in tailoring have a similar button on the side of the unit. The button causes the spring to lock into position. This locking feature allows the craftsmen time to properly measure the materials that he is working on. When the switch is released or the button is pressed again, the spring inside the casing contracts, and the tape measure is pulled back inside. Although it seems a little strange that tape measures should come in right and left-handed versions, there are left-handed versions available for southpaw craftsmen, hobbyists and construction workers.
