Abstract: 23,310. Muntadas y Rovira, M. Sept. 29, [date applied for under Patents Act, A.D. 1901]. Bleaching; dyeing; washing.-Relates to improvements in the bleaching-apparatus described in Specification No. 14,200, A.D. 1903. (1) The hydraulic seals which balance the different pressures are arranged so that the liquid (either the wash or the water) circulates in a contrary direction to that of the fabric. Where the wash is to be recovered, it is sent, after passing through the seals to the right, to those on the left of the central chamber. In this case, the injected wash is of a density of 20‹ BÚ., so that, when it has mixed with the recovered wash, it will be at the required working density, namely, 2‹ BÚ. (2) Consists of devices for causing the fabric to pass continuously in the same direction through the liquid. The principle on which this is done is shown in Fig. 4, wherein there are two open casings A', A', on each of which the fabric a is wound in a double coil. The casing A' has been fully wound up, and is now being unwound, while the casing A' is now being wound up, the fabric continuously entering between rollers R and continuously leaving through rollers R'. It is seen that one part of the fabric from the casing A' passes away as required, while the other half winds itself, along with fresh fabric, around the casing A<1>, and this will go on until the whole of the fabric has been removed from the casing A<2>. If then the casing A' can be transferred to the position occupied by A', and the latter, or another similar casing, takes the place of A', the fabric can still be continuously removed, this time from the casing A'. The loop of the fabric is held in the casings by a heavy bar v. In use, there is provided a disc C, Fig. 7, carrying three such casings A, A<1>, A<2> arranged symmetrically. As shown, the disc has been turned so that the casing A', upon which the fabric a has been previously fully wound in a double coil, is beginning to deliver the fabric to the rollers R, while the casing A is about to receive fabric both from the casing A' and from the feeding-rollers R. The bar v has just fallen through the casing A, carrying the fabric with it. The rotation then proceeds until the casing A<1> is empty, and A is full. The bar v from the casing A' is then raised in guides L, x as the fabric is further withdrawn, and reaches a recess in the disc c'. The disc C is then turned in the direction indicated, so as to carry the casing A to the position previously occupied by A', and to bring A<2> to the former position of A. In doing this, the disc c', which gears with the disc C, is also turned, and, as the radii of the two discs are in the proportion of 2 to 1, the rod v, kept in its slot by a curved guide f, is brought to the guide x<1>, and falls on to the fabric, which it carries into the casing A<2> as shown. The process is then repeated. In a modification, instead of open casings and falling rods, horizontal cylinders are employed having teeth which catch on to the fabric and hold it so that, when rotated, the fabric forms a double coil thereon. This part of the invention is applicable to continuous washing, vaporizing, washing with wash, dyeing, acidifying, mordanting, and like operations.
