There may even beone with STREHLENERT, a subject of the King of Swerotary motion around its own axle.

This bobbin is not shown.

, By the means herein described, which form. a part of the present invention, the filaments are twisted before they are wound, and any filaments whichmay be broken will be caught by an adjacent filament or filaments and stopping the apparatus. This propencatching of a. broken. filament'i's partly due to the revolutions ofthe cylinders and; their axial rotation and partly due to the fi 'otation of the the water or liquid is not absolutely necessary to the automatic reparation by the catching of' the broken filament. Good results can be attained without it. v

The water in the open reservoir l-i maybe supplied and renewed in any convenient manner. It washes the filaments, and when desired it may be drawn off by the removal of the plug 17.

In' the construction of Figs. 1 and 1'? just described the solution is used in successive charges; but it may be supplied in a .conti-nuous manner to the mouthpieces. An apparatus for such continuous operation is illus trated in Fig. 2, which will now be described. The large gear-wheel 2", which carries the cylinder or cylinders 5 is in Fig. 2 represented as a worm-wheel driven by a worm or screw 3 but this is not essential. inder or cylinders have no pistons or plungers, but receive, respectively, at the upper or their upper ends through suitable stufiingboxes the branch or the several branches .18 of a tubular spider 18, the central branch of which has a bearing in a stufiing-box in a tubular socketpiece 19, fixed in the frame. The solution for producing the filaments of artificial silk is supplied to this socket-piece 19 through a pipe 20, being supplied from some source under pressure and not herein shown, and it passes down through the spider 18 and its branches to the cylinder or several cylinders, and thence to the mouthpiece with one or several holes or several mouthpieces 6. In other respects the construction and operation are substantially the same as that seen in Fig. 1.. v

In the constructions of Figs. 1 and 2 the direction in which the solution flows through the apparatus is downward'vertically, the re- 7 volving and rotating parts moving about vertical axle or axes, and this is the preferred arrangement, as it permits the use of a simple open reservoir 14; but the apparatuses seen in The cyl- The construction of Fig. 3 is based on that of Fig. 2. 'an'd differs therefrom in substance only in the cylinders 5 having packed bearings in a disk 21, which forms a cover for the end of the reservoir 14, said cover having a packed bearing on the said reservoir. The latter has a filling-inlet 22 atits upper side. Obviously this construction is not so simple as that seen in the other views. Q

The words revolution""and revolving are herein used to express the movement of the words rotation and rotating to express the idea of the movement of a body about its own axis or center. I
