I saved a man's life today!
I was walking by the toolroom door, looked in the window and saw the toolmaker hunched over the lathe struggling wildly. I rushed in, the lathe is ten feet from the door, and by the time I got there his head was down on the ways and I could see his shirt was winding up in the feed rod. I stomped on the stop treadle as I got there. I asked him if he was OK and he said, "I'm not sure." I told him not to move and catch his breath for a minute. After a minute he thought he was all right and squirmed out of his entangled shirt. He was bleeding from a cut over his eye and bruised on his arm & ribs but otherwise OK. Another second and his arm and ribs would have been broken, a few more an his back and neck would have been as well. He is lucky I was walking by and happened to look in and I'm one of few others in the shop who know how to stop that lathe as it has no obvious stop button, just a red foot treadle gone black with age. He was unable to step on the treadle as the lathe was pulling him down so fast.
I didn't think too much of it at first, I just did what the situation called for but when my boss came to me later and thanked me for "saving the toolmaker's life" it kinda sank in. Recently near by at Yale a young girl was killed in a similar accident when her hair got caught in a lathe feed screw.
I too am one who often works with shirt unbuttoned and untucked, not a good idea around machines .
