Abstract: 4586. Brintons, Ltd., and Osborn, C. Feb. 29. Bleaching ; dyeing ; washing. - In apparatus for bleaching, dyeing, and washing yarns and slubbing in hanks or skeins carried on poles fixed to one or more cages which have a combined up-andd o w n and rotary motion in the vat, there are employed lifting-bars with cranked and hooked lower ends having racks which, on the up movement, engage with pinions on the axles of the cages and lift and turn the cages and then move d o w n and allow the cages to fall by gravity. Mechanism for rocking the shaft conveying the lifting-bars is described, and also, in the Provisional Specification, means for locking the poles in the cages and for lifting the cages out of the vat. Preferably a pair of double cages B<1>, B<2> is employed. Each cross-bar C<1>, C<2>, C<3>, &c. is preferably made with two rows of holes 31, 32, 33, 34 so that the poles may be fixed to take hanks of three different lengths. The axle ends 21 of the cages move in vertical guide-bars 22 and, when in their lowest position, rest on stops 30. The ends 21 also carry toothed pinions 26 which engage with racks 25 fixed on the slanting cranked ends of the lifting- bars 9. These bars 9 are carried, one each, by four arms 4, 6, 5, 7 attached to a rocking-shaft 1, carried on bearings 2, 3 fixed to the ends 23, 24 of the vat A. When the rocking-bar 1 is oscillated, as by an eccentric and suitable connexions 12, 14, 15, 18, 16, 17, the cages are actuated as follows. Any given lifting-bar 9, being in its lowest position, and maintained vertical by the action of a counterpoise 28, is raised ; the rack 25, previously clear of the pinion 26, now engages with it, and, owing to its slant, causes the cage to rotate, being itself driven sideways until the pinion 26 is embraced by the hooked end 27 of the crank and so supported until,_ the upward motion having been completed, the cage falls again to its previous resting place upon the stops 30. An automatic mechanism, Fig. 5, may be used for oscillating the rocking-shaft 1. It consists of a steam or hydraulic cylinder 57, to the piston-rod 58 of which is attached a rack 59 gearing with a quadrant 60 attached to the rocking-shaft 1. Ordinary cocks 63, 64 are alternately opened to pressure and exhaust by obvious means. When steam is employed the exhaust may pass into heating-pipes in the vat A. According to the Provisional Specification : (1) sliding locking-bars are mounted on the cross-bars of the cages ; and when a locking-bar is moved endways in one direction, holes in it aline with those in the cross-bar, permitting the poles to be removed or inserted ; when the poles are in position, they are locked by moving the locking - bar, so that its blank spaces come opposite the ends of the poles ; (2) the centre of the cage is made with a radial recess terminating in a cross-slot, into which a lifter is inserted ; this is made with a cross-piece at its lower end, so that a slight turning in the slot causes the ends of the cross-piece to engage, and the cage can be lifted out.
