F. PASCHKE El' AL DEVICE FOR THE TREATMENT OF' ARTIFICIAL SILK Filed Jan. 2, 1931 2 Sheets-Sheet 2 fave/220m:

in its essential parts of the distributing boX m for the liquid, having suitably attached pipe sockets n positioned at the same distances from each other as the holes in the .vashing frame. The said frames are placed onto these sockets and pressed down tightly by means of a knuckle lever 0 or the like.

The device according to the invention is preferably used not only for the washing of the threads but also for other wet treatments, especially for desulphurizing. In such cases the frames may remain in the washing device in which only the liquid is changed, or they may be removed and transferred to another device of a similar kind. After treatment the bobbins are dried in the same frames on which they had passed through their wet treatment.

As will be gathered from the foregoing de scription, the essential feature of the new process according,r to the invention consists in that the bobbins are placed in the washing frames directly at the spinning machines in which they pass through the whole yfurther process until the silk is completely dried and finished. Thus, from the spinning machines to the end of the process no more handling of single bobbins is necessary, but only of complete frames containing a large number of bobbins, whereby a time-saving and very convenient way of handling is provided. The best result-'gs of this new process can be observed with silk of the more sensitive kinds of which the output and quality have been y considerably improved.

The dried silk is preferably wound straightaway onto suitable bobbins or but it may, of course, also be reeled into the form of hanks as desired.

What we claim is:

l. In a device for treating artificial silk, a washing device comprising a distributing box for the liquid, a frame comprising a loose and a fixed side member situated opposite to each i other, bars between said side members for the reception of the bobbins and of interposed packing rings, means to lock said loose members in a raised position, holes formed in said fixed side members for the reception of said bars, the treating liquid passing 'lirough said holes on its Way to the bobbins, and pipe sockets on the distributing box in contact with said holes.

2. In a device for treating artificial silk, a portable frame for carrying silk bobbins, comprising in combination, a carrying member, a loose member situated opposite he first-mentioned member, means for connecting said members, a plurality of bars adaped to receive said silk bobbins and cr -ed by said members, packing rings on said bars, holes formed in the first-mentioned member and adapted to receive an end of each of said bars, a space being left letween the walls of said holes and said bars for The p of the treating liquid, cavities formed in the second-mentioned member and adapted to receive the other end of each. of said bas connec'fed with said means and second-mentioned member, m locking the second-mentioned ircn'iber.

3. In a device for treat' ,1g rtl al silk, a washing device comprising a distrilnning box for the liquid, a frame com'n'i a loose and fixed side member situated opposite each other, means for moving said loose member, means for maintaining said loose member in position, depressions f-,rmed in the loose member, holes formen in vthe fixed member, bars of cross-shaped section placed between said loose and ixed memE 5:, the ends of said bars being reduced for insertion in said depressions and holes, and pipe sockets on said distributing box in contact with said holes.

In testimony whereof we aiiix our signa` tures.
