Part of a series in Engineering on the textile industry at the 1873 Vienna Exhibition, this installment concludes the description of Schoenherr's power looms. It details the new patented weft-catcher (needle and lever mechanism that stops the loom when a weft thread is missed), Schoenherr's steel shuttle with spool holder, a Sächsische Webstuhlfabrik shuttle with wedge spool fastening, the shuttle-driving levers and springs, and the temple for cloth with strong selvages. Illustrated with engineering drawings; the author judges it among the best mechanical looms in use.
