13 June 2020 - Plague Journal Day 93

We all are still sheltering in place, but I'm here to keep you sane and entertained.One could hardly ask for much more than that, now could one?

Today is Sewing Machine Day. Sewing machines are pretty amazing to me. If you look at them, the needle just seems to go up and down, in and out the same hole it made, so how does that turn into a stitch to hold the material together? The secret is what else goes on underneath when the needle pierces the fabric.
When my father was an engineering student, his girlfriend (who later became my mother, but that's another story) suggested that he design a sewing machine as a class project when his professor was in the coffee shop with the two of them. Fortunately for Dad, the professor told him not to do that - sewing machines are much more complicated than engines and transmissions and the other things he was designing. Who knew?

Anyway, here are some animated gifs to give a sense of what's happening down there, going from the first version of a sewing machine up through how the work these days, along with a picture of just the threads to see how it gets knotted.






It's complicated, that's for sure. Nice job whoever thought of all this!


Keep Calm and Stay Away.
I'll be back tomorrow.
