YARN CARRIER.

Application led April 18, 1928, Serial No. 270,968, and in Germany February 12, 1927.

rI`his invention relates to yarn carriers or frames such as are used in dyeing textile fabrics for example, for suspending the yarn hanks in the dyeing or washing machine. In such machines with reversibly circulating dye liquor, the liquor tends to drive the suspended yarn hanks upwards when circulating in anupward direction. -Under these circumstances the hanks would float on the surface of the liquor and would rise partly out of the liquor if steps were not taken to hold the hanks down below the surface. For this purpose vit is customary to insert sticks or bars in the lower ends of the loops of the yarn hanks or else a lattice grating is placed at some distance above the yarn bars, which only permits the amount of lifting of the hanks from the place on which they rest that is re'- quired for uniform dyeing. These appliances hamper the free manipulation which is desirable for the transposition and the arranging of the bars and hanks. Efforts have been made to counteract this difliculty by coiling the yarn hanks tightly on the bars. This however gives rise to stratiications of varying density or thickness.

According to the present invention two yarn carrier bars situated at a distance apart from each other are employed, which are releasably connected with one another, and which can be freely manipulated together by the dyer like a simple yarn bar. The lower of these connected yarn bars serves for the suspension of the hanks and the upper for limiting the movement of the yarn beneath the surface of the dye liquor when the direction of movement of the liquor changes. The bars are made from a substance which cannot be forced upwards by the circulating liquid, such as, for instance, of metal unaffected by the liquid.

Various constructional forms of the invention are illustrated by way of example in the accompanying drawings, wherein Fig. l shows in longitudinal sectional elevation a dye vat with a number of suspended yarn carriers according to my invention,

Fig. 2 shows a cross section on the line 2-2 in Fig. 1,

Fig. 3 shows on an enlarged scale, partly in section, one end of a yarn carrier according to Figs. l and 2, and

Fig. 4 is a cross section on the line 4-4 in Fig. 3.

Fig. 5 shows in cross section the upper part of a dyeing or washing vat with another yarn carrier according to my invention, and

Fig. 6 is a partial section on the line 6-6 in Fig. 5.

As Figures l andQ show, the yarn hanks l are suspended in a vatQ, in which, by means of a partition 3, 4, compartments are divided off which communicate with one another. In these compartments the washing or dyeing liquor which fills the vat nearly up to its upper rim 5 is moved by a suitable pumping mechanism or the like in constant circulation, the direction of which is reversed from time to time.` Such vats are known.

The new yarn carrier consists of two parts 6 and 7 releasably connected with one another. t hangs down with its central part, the yarn bar 6, which receives the yarn hanks, between its supporting ends 8 and 9, in such a way that when the yarn carrier is placed upon the edges 5 of the vat, the yarn bar 6 is immersed in the liquor. The second bar, which forms the holding down ledge 7, is releasably supported in the yarn carrier 6 at a distance from the bar. For this purpose the supporting ends 8 and 9 of the yarn carrier are provided in the upright parts 10 with slot- like recesses 11 and 12, which are open at the top, asv shown in Figs. 1 to 4, and into which the bar can be inserted from above. It is a particular advantage of this method of supporting that the holding-down bar 7 can be inserted after the yarn carriers are suspended in the vat 2 and can be taken out before the yarn carriers areremoved. It therefore does not hinder the transposition and arranging of the hank carriers or of the hanks 1, the bar or ledge 7 which is situated at a distance above the yarn carrier 6 does not prevent the hank from being lifted fromthe carrier bythe dye liquor but it is situated so far below the liquid surface that it keeps the yarn hanks 1, which the liquid tends to drive upwardly when circulating below the surface of the liquid. l

In the second constructional form, illustrated in Figs. 5 and 6, the yarn carriers consist of simple straight bars or tubes 6, which are located underneath the surface of the liquor on steps or shoulders 18 in the vat 2. Over these straight yarn carriers the .yarn hanks 1 can be slipped more easily than over the yarn carriers 6, shown in Figs. 1 to 4, which are joggled at both ends. The holding-down bar or ledge 7 is here provided at llO both ends With clamps or paWls 14, Which, When the ledge carriers 15 are put on,-a=,t first yieldfto the carrying bar 6 and subsequently swing back and engage underneath the latter, as shown in Fig. 6. In this Waythe connection between the two bars 6 and 7 is established. Each carrier bar 6, hanging in the Y paWls 14 of its holding-down ledge 7, can be lifted out With this ledge and transposed, Without leaving the liquor, since the yarn bar located entirely underneath the surface of the liquor can be taken hold of by the handles 15. In this construction also the holdingdown ledges 7 can be mounted individually even after the introduction of the yarn carriers 6 into the liquor.

Vilhat I claim is 1. A yarn carrier, more particularly for hank yarn dyeing and Washing machines, comprising a carrying member, a holding down member situated at a distance above and releasably connected With said carrying member, said carrying member and said hold- `like a simple yarn bar.

2. A yarn carrier, more particularly for hank yarn dyeing and Washing machines, l

comprising a carrying bar adapted to have -hanks of yarn suspended therefrom, a holding down bar adapted to be releasably connected With said carrying bar, releasable paWls carried by said holding down bar, said pawls being' adapted, when the holding down bar is mounted upon the carrying bar, to hook firmly under said carrying bar, said carrying bar and said holding down bar co-operating With one another to holdthe suspended yarn hanls underneath the surface of the liquor and being freely movable together by the dyer like a simple yarn bar.

In testimony whereof I have signed my name to this specification.
