[00:02] thread. The rotating hook spins around, the first loop is released, and then the hook grabs the second loop. The looper was held by pieces of metal tightly enough of a gap for the thread to pass through all the way around. That same
[00:18] shape was used on over 80 models of sewing machines for 80 years. The second patent that Wilson received in 1851 is the basis for how most modern sewing machines work. The bobbin is inside a rotating hook. So, let's see
[00:34] how that works. The needle comes down pulling that top thread. And really low and then it pops back up a little bit creating this little bulge right here. And when the rotating hook comes around
[00:49] it is grabbed by that rotating hook pulling even more thread so that this thread can pass entirely around the bobbin. And then
[01:01] needle pops back up. We pull in the excess and we've formed another lock stitch like so.
