Three years later, in 1929, Stihl developed a gas-powered chainsaw version; however, Emil Lerp, founder of Dolmar chainsaw company, had already begun manufacturing gas-powered chainsaws in 1927. Although Stihl and Dolmar both created chainsaws around the same time, Andreas Stihl is credited as the person who invented the mobile and motorized chainsaw.

The modern-day chainsaws we’re used to seeing are mainly utilised for tree cutting. Shockingly, the chainsaw was originally invented to assist in childbirth – yes, you read that correctly. The doctors’ chainsaw was used during symphysiotomies.
One of the earliest patents for an “Endless chain saw” comprising a chain of links carrying saw teeth was granted to Frederick L. Magaw of Flatlands, New York in 1883, apparently for the purpose of producing boards by stretching the chain between grooved drums. “Usually, each segment in a chain features small, sharp, cutting teeth. Each tooth takes the form of a folded tab of chromium-plated steel with a sharp angular or curved corner and two beveled cutting edges, one on the top plate and one on the side plate. Left-handed and right-handed teeth are alternated in the chain. Chains are made in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets, while the gauge is the thickness of the drive link where it fits into the guide bar. The conventional”full complement” chain has one tooth for every two drive links. Lack of chain oil, or using an oil of incorrect viscosity, is a common source of damage to chainsaws, and tends to lead to rapid wear of the bar, or the chain seizing or coming off the bar.
when was first chainsaw invented Related Question:
When were chainsaws first used to cut wood?
The origin of chain saws in surgery is debated. A “flexible saw”, consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively.
Who invented the first chainsaw and why?
In the late 18th century, 2 Scottish doctors, John Aitken and James Jeffray, developed a prototype of the chainsaw—familiar today in the timber industry—for symphysiotomy and the excision of diseased bone. The design of the chainsaw was based on a watch chain with teeth that moved through the use of a hand-crank.
When was the chainsaw first used in logging?
THE SINGLE MOST IMPORTANT INVENTION affecting logging was the chainsaw of 1935. Although it was not invented in Oregon, it was perfected there in 1947 by lumberjack Joseph Cox. While chopping firewood one chilly autumn day in 1946, Cox paused for a moment to examine the curious activity in a tree stump.
How were big trees harvested before chainsaws were invented?
Up until the 16th Century there is no proof, that hand saws were used in forestry work. On the other hand, saw mills, which cut trunks into planks, had already been around for some time in the forest. Around 1500 Leonardo da Vinci also spent some time on saws.
What’s the best angle to sharpen a chainsaw chain?
Always file at right angles to the guide rail. The right sharpening angle depends on the saw chain and the wood that you want to cut. The sharpening angle will generally be between 25° and 35° – the harder the wood, the greater the angle.
How does a chainsaw work?
Instead of a rotating chain, they have a powered, reciprocating blade (one that moves back and forth) mounted on top of a stationary blade. As the electric motor whirrs into action, a crank pulls the moving blade past the stationary one and the cutter chops its way through your hedge.
What is Symphysiotomy operation?
Symphysiotomy is an operation that is done to increase the size of the pelvic outlet to permit vaginal delivery of a baby. The procedure involves surgically dividing, under local anaesthesia, the cartilage of the symphysis pubis.
What chainsaw do loggers use?
Stihl is the most popular chainsaw for professional loggers. It has a long-lasting chain, and you can also enjoy the exceptional cutting speeds available with this brand of chainsaw. Additionally, the chains are high-performance, low vibration, and quiet in their performance.
What year was the first gas powered chainsaw?
In 1929, Stihl patented the first gasoline-powered chainsaw called the tree-felling machine. These were the first successful patents for hand-held mobile chainsaws designed for woodcutting. Andreas Stihl is most frequently credited as being the inventor of the mobile and motorized chainsaw.
Who invented the saw?
According to Chinese legend, Lu Ban – a structural engineer, carpenter and inventor during the Zhou Dynasty, is credited with discovering the saw. After cutting his hand on a leaf with a spiny texture, he was inspired to replicate the serrated edge to create a tool.
How were the first trees cut down?
Polished stone axes, which will have been hafted, became ubiquitous in the Neolithic and were probably used to cut down trees. They were used until recently for the very same purpose in places like the New Guinea Highlands.
When was the first Stihl chainsaw made?
Company history Andreas Stihl designed and hand built his first chainsaw in 1926. The saw was electrically powered, and weighed about 48 kg (106 lb).
Were chainsaws used to deliver babies?
The doctors’ chainsaw was used during symphysiotomies. This was a procedure carried out on pregnant women during birth, in place of a caesarian section which is now the modern practice.
What is the biggest chainsaw made?
For the largest, toughest and most demanding jobs, professionals can find the performance they need in the MS 881 chainsaw. With its updated engine design and up to 41” guide bar length, the MS 881 is the largest, most powerful saw in the STIHL lineup.
Can a chainsaw cut through bone?
Bones may be slightly tougher, but they are rigid and a chainsaw will likely be able to cut through them without much problem – though it will probably dull the blade more than wood.
