Abstract: 8570. Partridge, S. S. April 14. Dyeing.-Relates to a machine for dyeing yarns and slubbings. The general arrangement is shown in Figs. 2 and 4. In the vat B, the swift A, made of teak or other hard wood, is suspended from a top beam C. To the ends of the beam C are fixed vertical slides c<1> c' moving in guides D<1>, D<2> fixed to the ends of the vat. The slides c<1>, c<2> carry rollers c<3>, c<4> resting on cross - levers E<1>, E<2> which turn on fulcrum pins e<3> and are connected by a cross-bar E<3> ; this cross-bar may be made in one piece with the levers, as shown in Fig. 4. In the arrangement shown, the crossbar E<3> rests on crankpins F<1>, F', fixed on revolving worm - wheels f<1>, f<2> which engage with worms g<1>, g<2> on a shaft G driven from the pulley g<3> ; the necessary up-anddown motion is thus imparted to the swift. The moving parts are partly counterbalanced by weights H hung on ropes h<1>, h<2>, which pass over pulleys h<3>, h<4> carried by brackets d<1>, d<2> on the guides D<1>, D<2>, the lower ends of the ropes being fixed to the lower parts h<5>, h<6> of the slides c<1>, c<2>. The top beam C carries banging arms I<1>, P, the lower ends of which form bearings for the axle J of the swift. The swift is formed with end frames a<1>, a<2> and crossbars a<3>, a<4> carrying the poles a<5>, a<6>, a<7>, a<8> ; the inner ends of these poles are carried by cross-bars a<10>, a<11> on the central frame a<9> ; the bars a'‹, a<11> are split to allow of removal of the poles when desired. The swift is given an intermittent turning motion by the ratchet-wheels K<1>, K<2> which, as the swift rises and falls, come in contact with ratchets L<1>, L<2>. Fig. 6 shows the arrangement by which the ratchets are set to take one, two, or more teeth of the wheels, or to clear them altogether. Each ratchet turns on a fulcrum l<1> carried by a bracket l<2>; this bracket also carries a set-screw l<3> by which the position of the end l<4> of the ratchet is regulated. When the ratchet has been adjusted so as to clear the wheel, the swift can be fixed to one of the arms I<1>, I<2> by means of a set-screw passing through one of the holes in the wheel into one. of the arms, so that the yarns or slubbings will be at any desired angle to the level of the liquor in the vat. The swift can be lifted out of the vat and turned end for end, if desired, by a pulley block and slings connected to the eyes c<5>, c<6> in the beam C. Two or more swifts may be arranged to work in the same vat, and, in the case of two, the levers are extended beyond their fulcrums so as to work the additional swift, which thus moves up as the other moves down. Fig. 12 shows an arangement for turning the poles without raising the swift out of the vat. A cross-shaft M is furnished with worms N gearing with worm-wheels 0 on the ends of the poles a<5>, a<6>, these poles being eccentrically mounted to give the required up-and-down motion to the materials. The shaft M may be operated by the attendant by means of a lever or other mechanism; the mechanism described previously for automatically effecting the up-anddown motion may then be dispensed with. Or, when the previously-described mechanism is used, the turning of the poles can be automatically effected by a ratchet-wheel on the end of the shaft M and a ratchet or pin fixed on the tank to engage with the wheel when the swift moves down.
