JET Box Filed 001;. 27. `.1.954
INVENTOR United States Patent JET BOX Ernest J. Griset, Jr., Asheville, N. C., assignor to @merican Enka Corporation, Enka, N. C., a corporation of Delaware Application October 27, 1954, Serial No. 465,019
4 Claims. (Cl. 68-181) This invention relates to continuous spinning of rayon yarn and more particularly to improvements in the art of tube spinning of the type described in Griset application, Serial No. 122,560, filed October 20,-1949, now Patent No. 2,725,276 of November 29, 1955, and commonly owned herewith.
In the Griset application, mentioned above, there is disclosed an arrangement for the after treatment of rayon yarn that involves introducing the freshly spun yarn into a tube through which the yarn is propelled by a liquid which also effects a treating operation. After leaving the tube, the yarn is introduced successively into other tubes which are so arranged that the yarn runs back and forth through the necessary number of tubes required to effect the desired after treatment. The liquid in each tube is introduced by a jet spaced from the tube mouth in such a way as to define a low pressure zone through which yarn is entrained for propulsion and treatment by the liquid. Yarn ejected from the exit end of each tube is guided by a deiiector to a position close to the low pressure zone of the next tube. Once the yarn is spun in, the establishment of a common path for both liquid and yarn from the exit end of one tube to the mouth of the next is undesirable and accordingly the deflectors are made to be movable to and from the pathway establishing position.
In commercial operations the various yglass tubes of the system occasionally become clogged or broken with a resulting requirement for replacement. To this end the tubes in which the yarn is after treated have been arranged in cradles as shown in application Serial No. 341,529, led March l0, 1953, now Patent No. 2,724,956 of November 29, 1955, and commonly owned herewith. By the use of these cradles it is possible to replace tubes with very minor interruption in the spinning operation and very small disassembly of the apparatus.
The original spinning in of the yarn to the system of tubes is accomplished by leading the freshly-formed thread to the top of a detiector, washing it with water through the deliector channel to the low pressure zone of the first jet-venturi of the system. The thread is then sucked into the system. This part of the spinning system is a little different from the rest because, instead of spinning in and thereafter treating the thread with a liquid, the water which is used to wash the freshly spun thread into the first jet-venturi is shut off once the yarn is running in the tube system. Nevertheless, in these boxes the nozzles clog and breakage does occur and it has therefore required about fifteen minutes time to make a replacement of a jet-tube unit in the first box of the system, commonly called the spinning in box. Furthermore, observation of the spinning in nozzle has been exceedingly ditlicult and leakage has been difficult to control.
It is an object of this invention to overcome the diiculties of the prior art and to provide a spinning in box for la tube spinning system which is characterized by ready manual and visual access to the jet-tube unit parts iiector is entirely now.
rice
whereby, in the event of damage to or clog-ging of a jet or tube, repair can be quickly and convenient-ly undertaken without major disassembly of the system.
Other objects and advantages of this invention will be apparent upon consideration of the following detailed description of a preferred embodiment thereof in conjunction with the annexed drawings wherein:
Figure 1 is a view in side elevation of a spinning in box constructed in accordance with the principles of the present invention;
Figure 2 is a plan view of the spinning in box of Figure 1; and i Figure 3 is an end view of the spinning in box of Figure 1 showing in broken lines the hinged side wall in its extended position. a
The spinning in box 10, according to the present invention, is a long narrow structure having a ,large internal cavity 11, the bottom defining wall of which slop from left to right as viewed in Figure 1 toward a drain outlet 12. Within the bottom of thebox 10 there is mounted a lead bracket or saddle 13 having a supporting stem 14 removably vseated in a socket in the bottom of the box 10, an arm 15 which supports la jet or tube 16 having a nozzle formed at one end and an arm 17 which supports a glass tube 18 having a flared mouth 19. The tubes 16 and 18 are commonlycalled a jet-tube unit. The arms 15 and 17 are s o located that the jet 16 is an axial registry with the ared mouth 19 of the tube 18, but spaced from itaxially a small but appreciable distance. When a liquid is supplied through the jet tube 16 it enters the tube 18. This creates a suction zone around the mouth 19 and thread is introduced into the system by bringing it into proximity with this low pressure zone. To this end a deector 20 is provided having a central channel at 21 connecting the outlet of a spigot 22 with the low pressure zone adjacent the flared mouth 19 of the tube 18. The spigot 22 supplies water which washes freshly spun yarn into channel 21 and along the channel to the venturi. The leftover liquid falls into the bottom of the box 11 and drains out the outlet 12.
The foregoing description involves no material new to this application but is necessary as a background in order that the improvements constituting the present invention may be understood. While the detiector 20 is similar in appearance to the corresponding parts shown in earlier applications of this applicant, the mounting of the de- It will be noted that ears 23 and 24 extend from the side wall of the box 10 on the left hand side thereof as it appears in Figure 3. Through these ears 23 and 24 there extends a hinge pin 25 which receives thereover ears 26 and 27 which extend outwardly from plate 28. By this arrangement it can be seen that the plate 28 is hinged to move from the full line to the broken line position depicted in Figure 3. Fastened to the inner wall of the plate 28 by two screws 29 is the detiector 20. Thus, when the plate 28 is swung out to the broken line position of Figure 3, the detiector moves with it and in so doing affords easy access both visual and manual to the tube 16 which lies below the deector as can be seen from Figure 2.
An ordinary cylindrical porcelain thread `guide 30 passes through the wall 28 and through a corresponding wall 31 on the right side of the box 10 as it is viewed in Figure 3. The wall 31 is stationary and when rubber washers 32 and 33 are placed over the ends of .guide 30, hinged wall 28 is held in its upright position fromwall 31 through `guide 30 but it is held in a way which renders disconnection and movement thereof very easy.
Of course once the yarn path to the mouth 19 of the tube 18 has been estab-lished and the yarn is running in the system it wil-l no longer occupy the channel 21 of the deector 20.v Instead it will pull up to the broken line b position of Figure 1 passing under the thread guide S and from there into the mouth '19.
In the event of clogging of the jet 16 all the operator needs to dois to remove one of thewashers 32-,33, Vslip out the -guide 30, .swing the side .2,8 to the broken line position in Figure 3, and ulift out :the kassembly including tube 16, tube vI8 and saddle 13. The tube 16 fis held in a resilient U member 34 at thev left hand end of `the box 10 and can be lifted out. The bearing for the tube 18 is a part of arm 17 of saddle .13. The left hand `end of the jet tube 16 and -the right `hand end of the tube 18, both as shown in Figure 1 Yare provided with enlarged portions for the purpose of receiving .a short length of exible tubing to connect them into the system.
