the first power tool

Is there something "you" want to share with us? Are you suggesting that you are a man in drag or visa versa?

I was simply pointing out the recognition of a woman's contribution.

There seems to be some confusion here. The woman invented the circular blade design. I'm clueless who invented the circular saw.

Well, I'll admit to being confused how you could have a circular saw without a circular blade...

I'd agree. Steam powered saw mills I've seen from the 1890's (sample size of 2) have two blades, a large one for ripping, and a smaller one mounted on a swinging arm crosswise to the carriage, to cut boards to length.

The swinging arm allowed the blade to move, which otherwise would be difficult with a belt drive.

I'd guess someone figured that arrangement out very soon after they figured out how to spin the ripping blade.

In that case you should have used _underlining_ or *bold*.

So if she did not invent the circular saw then what was the purpose of the circular blade design? Were the Shakers playing high-stakes Frisbee or something?

A big pulley on the shaft of the wheel and a small pully on the shaft of the saw, with a flat belt, can run the saw much faster than the wheel with no gears, and higher efficiency.

I'm sure the machine to run the blade came a touch later. But for sure there was no circular saw before there was a circular blade. ;~)

The need was for a more efficient and durable design. The dual stroke of the straight blades only cut in one direction. The return stroke was a wasted motion as far as cutting was concerned. The circular blade never has to reverse direction to continue the cycle.

I'm sure you could envision how spinning the circular blade would not be a stretch of the imagination.

No all of this is with the assumption that we both agree that a circular saw spins a circular blade.

Ackshooley, the old two man crosscut saw I used cut on both strokes. The teeth were symmetrical in both directions.

Yeah,,, but were you around in the early 1800's when the circular blade was invented to replace the single stroke in the saw mill? LOL

Are you being deliberately annoying or do you have something wrong with you?

I'm sorry if the answer is still too complicated for you to understand. I tried to explain in the simplest way that I could when you asked what seemed to be a simple question. Perhaps you did not understand the question you asked. It's not really complicated.

Reread your question several times and my answer the same amount of times. That might help.

So just to clarify, you asked, So if she did not invent the circular saw then what was the purpose of the circular blade design?

Consider this. A saw, any saw, a circular saw, will not cut with out a blade. A blade is not a saw. A saw can be a saw with out a blade. So if you were thinking that a circular blade is a circular saw, I can see how you would be confused on the whole issue.

She came up with a better design blade, some one else came up with a way to operate the blade, The machine/tool that operates that circular blade would be called a saw, and or circular saw.

I agree, but the OP's question was rather vague and the followup answers wandered all over the place as well.

Just to throw some more sh*t in the game, the first time a human hooked an animal to any device that performed some sort of work on behalf of said human could probably be said to be a power tool driven by other than the user's hand power.

When were the Pyramids built? Inca temples? Surely if a system of ropes and pulley or levers were employed they would be classed as tools. Add one animal to the equation and we're talking power tool in the context of the OP's question

This circular argument needs to stop! ;)

I'm sorry, but you're babbling incoherently. You've been doing enough of that lately to make me worry for your health. Please get a checkup and be sure to inform the physician that others tell you that you babble incoherently at times.

Well, with apologies to Unquestionably Confused, it seems evident that circular saws existed long before Ms Babbitt. Ergo, since the blade must have existed before the saw by your own admission, Ms Babbitt did not invent either the saw or the blade.

OP specifically excluded tools using animal power (which presumably also includes human power).

There's a bit of a fuzzyness there, tho, if you consider stored power. If an animal compresses a spring, or carries water to an elevated tank, and that is then later used to power a tool is it still animal powered?
