Abstract

121,075. Lord, J. S., and Lord, S. S. April 27, 1918. Hank type.-One or more sets of radial arms l, carrying hank-supporting rollers m, q and locsely mounted on a driving-shaft d, are rotated intermittently, and simultaneously the rollers are rotated on their axes, the rollers q being adapted to be moved automatically into and out of frictional engagement with rollers i secured to the shaft d. The rollers q are loosely mounted cu spindles p, which extend through slots o, Fig. 4, in the arms l and work in bearings r, Fig. 2, su.spended from the arms by springs s. Collars on the spindles p co-operate with fixed cams t in the framework, so that when the arms l attain the position P, Fig. 4, the corresponding rollers q are moved out of engagement with the rollers i, and simultaneously catches 9 on a spindle 8 engage the spindles p of the lowermost. arms and hold all the arms against rotation, permitting the attendant to replace the hanks; the catches 9 are withdrawn by depressing a counterweighted lever 7. Whilst the hanks 4 are moving through the liquid in the tanks c, they are pressed against the rollers i by two springs 5, which are secured to the framework and engage collars 6 on the spindles p. The pressure upon the hanks is varied by adjusting, by means of a screw 2, the pressure of a coiled spring z bearing on a leaf spring y, which is contained in a groove x in the cam t and presses on the collars v. The rollers q may be driven by spur-gearing from the shaft d.
