It has been shown how the rotation of the spindles is produced. For winding-on the yarn the carriage has a peculiar apparatus, which we shall aow describe. In front of it, through the whole extent to the right hand as well as the left, a slender iron rod, d$, runs horizontally along, in a line somewhat higher than the middle of the copping portion of the spindles, and is supported by several props, such aj e». Upon each end of the two rods, ds, there is an arm, g5; and betwixt these arms an iron wire, called the copping wire, /s, is stretched, parallel with the rod fc. For the support of this wire, there arc several slender bent arms As extended from the rod f at several points betwixt the straight arms g. The rod d5 has, besides, a wooden handle at the place opposite to where the spinner stands, by which it can be readilj grasped. This movement is applied at the left division of the machine, and it is communicated to the riffht by an apparatus which resembles a crane's bill. The two urms, g, in the middle of the machine, project over the rods fc, and are connected by hinses with two vertical rods_/s, which hang together downwards in like manner with two ama fc, proceeding from a horizontal axis te. By means of that apparatus the yarn is wound npon the spindles in the following manner. A6 long as the stretching and twisting go on, the threads form an obtuse angle with the spindles, and thereby slide continually over their smooth rounded tips during their revolution, without the possibility of coiling upon them. When, however, the spinling process is completed, the spinner seizes the carriage with his left hand and pushes it back toward...
