Yarn Tester
Page 1 of 1, a sample page, at reduced quality. Open the document to read it in full.
A short dictionary entry describing two 19th-century yarn testing devices. The first, a wall- and floor-mounted machine with a crank, measures the breaking weight in pounds and the stretch of a 120-yard knot of yarn. The second winds yarn onto a black board with a screw-driven guide so that unevenness and impurities can be seen. Two engraved figures (Figs. 2547 and 2548) illustrate the machines.
