coupling 3.

Heretofore in the art it has sometimes been the cusvent the clots of particles of foreign matter from re n-chiom to utilize platinum strainers and spinnerels due to the resistant chemical qualities of platinum. In utilicing hard rubber, however, it is obvious that the cost is reduced many fold and at the sometime the spinnerets may be inade thin enough to enable the niinutelike vperforations to be drilled therein. having predeterruined and uniform diameters, I have found that spinncrets a'nd strainers inade oi thin hard rubber or similar rnaterial are sufliciently strong to with-stand the great pressureoi the viscous fluid without becoming distorted. The thin hard rubber spinner-ct and strainer. flanged as illustrated and described, will act to secure themselves more firmly in position in the spinning head by virtue of the heavy pressure of the viscous fluid againstiheir inner faces, causing the same to be put nnder'tension.

which tension is transferred to the flanges. thus tightening the same against the tapering interior surface of the rings 8 and 12. respectively. v

Referring to Figs. 3 and 4, the bushing 2 has an annu lar projection 2 against which rests-the inner end of the In this modification the inner wall 15 of of the coupling is tapered to conform with the conically flanged portion of the strainer 7 and the spiim'eret 11. thus eliminating the necessity for the rings 8 and 12 respectivelyas shown in Fig. 1. The packing rings or washers may be dispensed with in this' modification since the inner ends of the

rings

6 and 10 present a surface against which the viscous fluid may act under pres sure. By virtue of this latter construction the viscous fluid not onlyeauses the strainer and spinneret to clamp themselves more securely in position. as described in Fig. l, but causes an additional clumping actiorrhy forcing the

rings

6 and 10 respectively, further into the flanges.

In the modification illustrated in Figs. 5 and 6, I have provided a structure in which the strainer may be made considerably larger than that illustrated in the preceding figures. in this case the coupling 3 is enlarged at its inner end and fitted over the large bushing 2". On account 05 thisconstrnction the strainer might not re duce thepressure oi the viscose between the strainer and the spinneret sufficiently to dispense with mechanical means for holding the strainer tightly against the inner tapering surface of thecoupling 3 of the spinninghead. I. therefore preferto screw the bushing 2 down againstthe inner ends of the ring 6 and strainer 7 to force the flange of the strainer tightly against the. inner tapering Wall of the coupling. Under such conditions, 'however, even with this construction the spinncret might be held in its proper position by the pressureoi the viscosealone as has'been heretofore explained Froni the above description i-t-will be apparent that I have provided a structure .in which both the strainer and the spinneret may be made of very light or thin ma.- terial which can be drilled or pnnched'to provide them :with suitable perforations, but at the same time thesaine are so-mounted within the spinning head that they are pie vented from collapsing-or varying substantially from their original form, notwithstanding. the high pres sure to whiehthey'are subjected and the tender It is 0i course to be understood that in order to pre- 'r v the viscose to force the-same outwardly through the con-' tractcd opening in the cadet the head.

ing the spinneret the holes or perforations in the strainer must ncccssarilybo slightly smaller than those in the spinnerct.
