The history of circular saws is a fascinating one, with claims and counterclaims about who invented them and when. From ancient civilizations to modern-day innovations, the evolution of circular saws is a testament to human ingenuity and the constant quest for efficiency.
In this article, we’ll explore the history of circular saws and shed light on when they were first invented. So, sit back, relax, and let’s dive into the world of circular saws!
When Were Circular Saws Invented
The use of circular saws can be traced back to ancient civilizations, with evidence of their use by the people of the Indus Valley Civilization. However, the modern-day circular saw that we know today was invented towards the end of the 18th century.
Before the invention of circular saws, logs were sawn by hand using a pit saw or powered saws with an up-and-down motion. The rotary nature of the circular saw required more power to operate, but it cut faster because the teeth were in constant motion. The sound of the circular saw is different from that of an up-and-down saw, earning it the nickname “buzz-saw.”
Sawmills first used smaller diameter circular saws to resaw dimension lumber and for edging boards. As technology advanced, larger diameter saw blades began to be used for head saws and to cut clapboards.
Claims to the invention of the circular saw include a little-known sailmaker who obtained a patent in 1777 for a saw windmill, a German inventor in 1780, and a blockmaker in Southampton who had circular saws in the 1790s. There are also claims that it originated in the Netherlands in the sixteenth or seventeenth century.
The use of a large circular saw in a sawmill is said to have been invented in 1813 by a Shaker inventor who noted the inefficiency of traditional saw pits used by sawyers in her community and sought an improvement. However, this claim is mostly discredited.
Early Origins Of Circular Saws
Circular saws have been used by civilizations throughout history, but the modern-day circular saw that we know today was invented in the late 18th century. Before the invention of circular saws, logs were sawn by hand using a pit saw or powered saws with an up-and-down motion. The rotary nature of the circular saw required more power to operate, but it cut faster because the teeth were in constant motion.
Claims to the invention of the circular saw include a little-known sailmaker who obtained a patent in 1777 for a saw windmill, a German inventor in 1780, and a blockmaker in Southampton who had circular saws in the 1790s. There are also claims that it originated in the Netherlands in the sixteenth or seventeenth century. However, these claims are disputed and difficult to verify.
One interesting claim is that the use of a large circular saw in a sawmill was invented in 1813 by a Shaker inventor, Tabitha Babbitt. She noted the inefficiency of traditional saw pits used by sawyers in her community and sought an improvement. While this claim is mostly discredited, it is worth noting that Babbitt’s design was innovative and ahead of its time.
The Industrial Revolution And The Rise Of Circular Saws
The invention of the circular saw coincided with the Industrial Revolution, which brought about a significant change in the way goods were produced. The circular saw was a crucial tool in the mass production of lumber, which was in high demand during this time.
With the rise of steam power and other forms of mechanical power, circular saws became more efficient and powerful. They were used not only in sawmills but also in other industries such as metalworking and plastic manufacturing. The circular saw’s versatility and efficiency made it an essential tool for many industries.
The development of electric power in the early 20th century further increased the popularity of circular saws. In 1923, Edmond Michel developed the first electric handsaw, which led to the creation of handheld circular saws. These portable saws allowed workers to cut materials on-site, making construction and renovation projects faster and more efficient.
The radial arm saw, invented by Raymond Dewalt in 1922, was another significant advancement in circular saw technology. This saw could perform a variety of operations by moving or rotating the motor and saw blade suspended on an overhead arm. This innovation made cutting materials even easier and more precise.
Today, circular saws are commonly powered by electricity and are used in various industries and applications. They have become an indispensable tool for contractors, woodworkers, metalworkers, and DIY enthusiasts alike. The evolution of the circular saw has come a long way since its invention in the late 18th century, and it continues to play a crucial role in modern-day manufacturing and construction.
The Debate Over Who Invented The Modern Circular Saw
Despite claims of the circular saw’s invention dating back to the 18th century, there is still debate over who actually invented the modern circular saw that we know today. One prominent figure associated with the invention is Tabitha Babbitt, a woman from Harvard, Massachusetts who was a member of the Shaker community. She reportedly observed two Shaker men using a traditional pit saw and noticed that half of their motion was wasted. She proposed creating a round blade to increase efficiency and eventually attached a circular blade to her spinning wheel, using the pedal of her wheel to power it. The circular saw was then connected to a water-powered machine to reduce the effort required to cut lumber, making it faster and more efficient with half the manpower.
However, there are conflicting accounts of Babbitt’s invention and its true origins. Some argue that she did not actually invent the circular saw and that it was already in use at Mount Lebanon Shaker Village by Amos Bishop or Benjamin Bruce in 1793, or possibly by someone outside of the Shaker community altogether. Additionally, there are claims that two French men patented the circular saw in the United States after reading about Babbitt’s invention in Shaker papers.
Despite this controversy, Babbitt’s contribution to the development of the circular saw cannot be denied. Her innovative design paved the way for modern-day circular saws and revolutionized the lumber industry.
Advancements In Circular Saw Technology
Over the years, circular saw technology has continued to evolve, resulting in more efficient and effective saws. One significant advancement was the invention of the sidewinder circular saw in 1928 by Art Emmons for Porter-Cable. The sidewinder design allowed for a more compact and lightweight saw that was easier to handle, making it a popular choice among professionals and DIYers alike.
In 1937, the Model 77 circular saw was born, which became a game-changer in the industry due to its high power and durability. This model was quickly adopted by professionals in the construction industry and remained popular for several decades.
Another significant advancement was the development of battery-powered circular saws. In 1985, Panasonic Electric Works was granted a patent for a battery-powered circular saw, which allowed for greater mobility and flexibility on job sites. More recently, in 2009, the US Patent Office granted Milwaukee Electric Tool Company a patent for lithium-based battery packs, further improving the efficiency and performance of battery-powered circular saws.
Today, circular saws come equipped with various features such as laser guides, dust blowers, and LED lights to improve accuracy and visibility during use. Additionally, advancements in blade technology have resulted in specialized blades for cutting different materials such as metal, concrete, and tile.
Circular Saws In Modern Woodworking
Today, circular saws are an essential tool in modern woodworking. They come in many forms, including hand-held, table saws, and chop saws. Circular saws are used to cut a variety of materials such as wood, masonry, plastic, and metal.
Circular saws have revolutionized the woodworking industry by making the cutting process faster and more efficient. They have replaced traditional hand saws that require more time and effort to complete a task. The versatility of circular saws has also made them popular among DIY enthusiasts and hobbyists.
In recent years, advancements in technology have led to the development of cordless circular saws that outperform corded models. Lithium-ion battery technology has made cordless circular saws more powerful and longer-lasting than ever before. This has made them even more convenient for use on job sites where access to electrical outlets may be limited.
Circular saws have also found new uses outside of traditional woodworking. They are now mounted on booms or the front of tractor-like machinery for tree trimming and log felling operations. This has made these operations much safer and more efficient.
In conclusion, circular saws have come a long way since their ancient origins. They have played a crucial role in modern woodworking and continue to find new uses in various industries.
