Triumphs and wonders of the 19th century, the true mirror of a phenomenal era, a volume of original, entertaining and instructive historic and descriptive writings, showing the many and marvellous achievements which distinguish an hundred years of material, intellectual, social and moral progress .. . EARLY SPINNING JENNY. spindles when unevenly loaded ; but with admirable foresight, developingintellects set to improve the spindles themselves, and, in 1871, Jacob introduced and patented a spindle and bearing, which was one of themost important improvements in the ring frame. He chambered the bobbin,and by carrying the bolster T well up inside supported the former near itsload centre. The evolution of the spindle was not yet complete. The Sawyer type, atmore than seven thousand revolutions, would vibrate, and of the manyattempts to cure the defect none succeeded fully until the very simplechange made by Mr. Eabbeth in 1878. He gave the spindle a small amountof play by making the bolster loose in its supporting case, and placed a pack-ing between the two. A. H. Sherman improved upon the Eabbeth structure by making the bol-ster and step in one piece and omitting the packing, the cushioning beingdependent upon the lubricating GINNING COTTON.
