Janice, my sister, had been pestering her husband, a carpenter, for more than a decade to build a screen door for the kitchen.
One day, to her delight, he built and installed one in less than two hours. It was both practical and pretty. She glanced towards the front door and wistfully remarked that one would look good there, as well.
"Are you kidding?" he gasped. "You can't just whip these things up, you know. It takes ten years to build a door like this."
John ThorpDied 15 Nov 1848 (born 1784).American inventor of the ring spinning machine (1828), which by the 1860s had largely replaced Samuel Crompton's spinning mule in the world's textile mills because of its greater productivity and simplicity. The ring frame is a continuous spinner, which spins yarn and winds it onto bobbins in one motion, while the mule was a discontinuous spinner, first spinning a length of yarn and then winding that length onto bobbins separately. In ring spinning, a "c"-ring travels at a high speed around a grooved circular raceway mounted on a plate, which in turn travels up and down the spinning bobbin. |
