Gullen Whipple, of Providence, R. I., has invented an improved method of drawing cotton, wool, flax, and other fibrous materials, by means of a revolving toothed or card clothed cylinder and a single pair of drawing rollers, which draw the fibers directly from the teeth of the card cylinder ; the surfaces of the rollers revolving as much faster than the surface of the cylinder as is requisite to produce the required amount of drawing. This mode of drawing produces a more uniform sliver, especially from stock that is of different length as wool and cotton mixed, than the ordinary mode where four or six rollers are useu.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
