A supplement to Ures Dictionary of Arts, Manufactures, and Mines, : containing a clear exposition of their principles and practice. . in fifj. 2046, the can roving frame; 4 rows of draught rollers instead of 3 ; and lastly, anapparatus for lifting all the roller weights from off the rollers at any time when the framemay be stopped. The stul)bing frame {ficj. 2046) is the first machine which puts twist into the silver, andprepares it for the roving frame, which in its principle it precisely resembles. 2046. The preliminary spinning process is called rovinrt. At first the torsion is slight in pro-portion to the extension, since the solidity of the still coarse sliver needs that cohesive aidonly in a small degree, and looseness of texture must be maintained to facilitate to theutmost the further elongation. Fig. 205 shows the latest construction of a bobbin and fly frame, as made by & Sons, of Manchester. As the principle of action is similar to that already de-scribed, it only needs to add that many improvements have been introduced by the makers,as will be seen on reference to the engraving. 1 represents a front view of the frame; 2 aview of the back of the frame; 3 shows the driving pulley and gearing end ; and 4 thesame end with the iron casing removed, so as to exhibit the works inside. The spindles and bobbins being now driven by gearing instead of by bands as formerly, - and greater strength of materials being introduced throughout tiie frame, it is capable of pro
