The speed of the ring frame, as well as its output, appeared unbounded;but at high speeds, under unbalanced loads, the spindles were found tovibrate in their bearings, and the quality of yarn, in consequence, degener-ated, the spindle bearings became worn, and the limit seemed to be reachedat five thousand revolutions per minute. A careful examination of the ringframe revealed no vulnerable part of its general structure that could beimproved so as to readily secure increased speed and steadiness of the. 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 th
