SPINNING BUCKET Filed Nov. 12, 1947 INVENTOg. HUGH D. HALEY Patented Dec. 27, 1949 UNITED STATES PATENT OFFICE American Viscose Corporation,
Wilmington,
DeL, a corporation of Delaware Application November 12, 1947, Serial No. 785,340
14 Claims.
This invention relates to an improved metal spinning bucket.
Metal spinning buckets have been used for the collection of freshly spun filaments, such as those obtained from the coagulation of viscose solution in an acid coagulating bath, but considerable difliculty has always been encountered in suitably protecting such a bucket from the corrosive liquids introduced by the filaments collected therein. It has heretofore been suggested to protect such buckets with a corrosion-resistant coating but such coating has been found to be unreliable, particularly wherever perforations are present in the wall or rim of the bucket. Either the coating failed to penetrate through the entire bore of such perforations or it is non-uniformly applied so that it wears away soon after the bucket is put into operation. To avoid the provision of perforations through the wall of the bucket, other means have been suggested to cope with the problem of getting rid of liquids introduced into the bucket by the filaments when metal buckets are used. For example, a grooved liner has been suggested. Holeswere previously tried in the lid for the purpose of getting rid of the liquid introduced into the box by the filaments, but this has been found unsatisfactory, as the rubber rings have to be made of a small diameter or slotted in order to allow the liquid to slide up the inside taper of the box to escape around the outside of the ring and through the holes in the lid. Again, it has been proposed to provide a large bore in the bucket wall wherever a small perforation is desired and to fit a perforated plug of corrosion-resistant material within such bore. All of these systems are relatively complicated and increase the initial cost and maintenance of such metal buckets.
It is an object of the present invention to provide an improved metal bucket which is effectively protected from corrosion and yet is of simple construction and adequately takes care of the discharge of liquids introduced therein by the filaments.
In the drawing, which is illustrative of the invention,
Figure 1 is an axial cross section through a bucket formed in accordance with the present invention,
Figure 2 is a plan view thereof,
Figure 3 is a section on line IIIIII of Figure 2, somewhat enlarged, and
Figure 4 is a plan view of a segment of the bucket rim somewhat enlarged.
As shown in the drawing, the bucket of the present invention comprises a solid unperforated wall 3 extending from a bottom 4 similarly unperforated and terminating in a rim 5. The bucket is an integral structure made of any. suitable metal, such as stainless steel, titanium, or preferably a light metal or light metal alloy such as aluminum, magnesium or aluminum or magnesium alloys, or the like and its internal surface may be provided with a taper in conventional fashion so that the yarn cake formed therein may be readily removed by virtue of the larger internal diameter near the open end of the bucket. The entire bucket is covered with a coating of lacquer or equivalent material having corrosion-resistant properties. A lacquer of phenol-formaldehyde resin such as Bakelite or Heresite, chlorinated rubber, rubber itself, or equivalent rubbers, resins, or synthetic rubbers or resins of the vinyl type including those known by the trade name of Tygon.
Within the rim of the bucket it is formed with a shoulder or seat at 6 to receive a cover or lid 1 provided with a central opening 8 to permit the introduction of the filamentary material such as by means of a conventional funnel guide. A groove 9 is provided adjacent the shouldered portions to receive a retaining member, such as the ring l0 of rubber which serves to hold the cover in position. The bottom of the groove is preferably arcuate though it may be straight if desired. One or more grooves or notches H extend from the open end of the rim 5 to the groove 9 or even to the seat 6. As shown more clearly in Figures 3 and 4, the bottoms of these grooves II are preferably tangent to the groove 9 at its deepest portion as measured from the center of the bucket though, if desired, it may be deeper than the groove 9. The bottoms of the grooves ll may be parallel to, but are preferably sloped from the parallel to, the axis of the bucket so that they become farther away from the center of the bucket as the open end of the rim is approached. These grooves preferably have an arcuate bottom as viewed in transverse crosssection and the slope of their bottom is preferably from 1 to 5 from the parallel to the axis of the bucket.
The provision of the axial grooves l l extending from the deepest part of the groove 9 for the cover-retaining means, which may be a ring of rubber or the like, has been found to provide adequate discharge of the liquid from the bucket. In addition, the entire surface of such grooves can be readily and uniformly coated with the .sumption of power during operation is reduced to a minimum. This power-consumption is also desirably reduced as a concomitant of the ability to employ a relatively strong bucket made of thin metal. There is also a slightly greater amount 7 of acid retained in the cake in a box without drainage holes, which also permits the cake to be removed more easily.
It is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
I claim:
1. A metal spinning bucket of which the bottom, wall, and rim are free of perforations, said buckethaving an annular seat within its rim adapted to receive a cover, a groove on the inside wall of the rim for receiving means for retaining the cover in position, and a plurality of short grooves extending from the open end of the rim in a generally axial direction along the inside wall of the rim clear through to the firstmentioned groove, the bottom surfaces of the short grooves being disposed at a distance from the central axis of the bucket at least as great as the radius of the bottom of the first-mentioned groove, said bucket having all of its surfaces including the walls of the grooves provided with a coating of corrosion-resistant material.
2. A spinning bucket in accordance with claim 1 in which the short grooves have their bottoms parallel to the bucket axis.
3. A spinning bucket in accordance with claim 1 and in which the axial grooves have their bottom surfaces sloped away from the parallel to the bucket axis so that the bottom of said grooves is farther from such axis at the end of the bucket rim.
4. A spinning bucket in accordance with claim 1 'in which the bottom surfaces of the short grooves are tangent to the bottom ofthe firstmentioned groove.
5. A spinning bucket in accordance with claim 1 in which the bottom surfaces of the short grooves are deeper than the bottom of theflrst-mentioned STOOVB.
6. A spinning bucket in accordance with claim 1 in which the bottoms oi the axial grooves are inclined between 1 and 5 from the parallel to the bucket axis so that the bottoms ofsaid grooves are farther from such axis at the end of the bucket rim.
. 7. A spinning bucket in 6 in which the metal is a light .metal alloy.
8. A spinning bucket in accordance with claim 6 in which the metal is aluminum.
9. A spinning bucket in accordance with claim 6 in which the metal is an aluminum alloy.
10. A spinning bucket in accordance with claim 6 in which the metal comprises magnesium.
11. A spinning bucket in accordance with cia'im 6 in which the metal is a magnesium alloy,
12. A spimiing bucket in accordance with claim 6 in which the metal is a stainless steel.
13. A spinning bucket in accordance with claim 6 in which the bottom surfaces 'of the. short grooves are tangent to the bottom of.the first mentioned groove.
14. A spinning bucket in accordance with claim 6 in which the short grooves extend to the an nular seat.
