Chalk line tool3/16/2023 The folding rule consisted of smaller six-inch rulers that were joined together by pivoting hinges and could extend to a length of over six feet. One of the more popular rulers for carpenters is the folding rule, invented by Anton Ullrich in 1851. Throughout the years, rulers have been created in many shapes and sizes, and have used a wide variety of materials from copper and ivory to the more traditional wood and metal. The ruler is a staple in any workshop, acting as a basic tool for measuring length, drawing lines and serving as a guide for cutting. Some of the first rulers date all the way back to 2650 B.C. Today you will see measuring wheels used most often for construction, road marking and paving, fencing, surveying, traffic control and insurance purposes. In fact, measuring wheels were often made by the wheelwrights responsible for making and repairing wagon wheels.Īlthough this valuable measuring tool has evolved in its design, it functions in much the same way it did hundreds of years ago. While today’s instruments are primarily made from aluminum and come in many shapes and sizes, the first measuring wheels were created using wood and sometimes iron for added support-imagine a wagon wheel. The earliest surveyor’s wheels worked a lot like the odometers we use today, which isn’t surprising since the two instruments share the same origin that dates back to Ancient Greece. Ideal for measuring long distances quickly, the measuring wheel has been around since the 1600s. Regardless of what you call this trusty device, measuring wheels have been around for centuries, helping professionals measure distances easily and accurately. You may know the measuring wheel by many different names – surveyor’s wheel, click wheel, hodometer, waywiser or trundle wheel. Let’s take a look at some of the most popular measuring tools we use on job sites and see how they evolved into the modern tools we depend on today.Įxample of a measuring wheel from the 1800s. Luckily, we’ve come a long way from the days of using belts, thumbs and cubits for measurement, but it’s always nice to know more about the tools you use every day. Often considered the first unit of measurement, the cubit was developed by the ancient Egyptians and was the length of the arm from the elbow to the tip of the middle finger (about 18 inches). An inch was considered the width of a thumb, a foot was just that-the length of a foot-and a yard was the length of a man’s belt. The first measuring tools were actually based around the human body, which is how some of today’s measurement standards got their name. We still carry many of these basic measurement principles with us today and use them in the modern world. They served as a valuable frame of reference that enabled ancient civilizations to build, trade and create. Since the beginning of time, measurements have played a major role in history.
