Description
Patented Feb. '19, 1952 UNITED STATES PATENT OFF-l-CE' METALLICALLY SHEATHEDBUCKET RIM Hugh D. Haley, "Drexel Hill, Pa.,*assignor'to-'American Viscose Corporation, Wilmington, Del., a corporation of Delaware Application August-.129, 1950, Seria1No.181,965

The present invention relates to spinning buckets, particularly to corrosion-resistant buckets of metallic construction.
Many of the preferred metallic materials used for fabricating spinning buckets have, in general, the disadvantage of not being completely resistan't'to corrosion, particularly when used to collect yarn produced by the regeneration of cellulose from a viscose solution. Various resinous coatings which are resistant to the corrosive materials that are present in the viscose process of making rayon may be applied to the metallic buckets but, in general, these resins lack the toughness "to resist the abrasion and chafing to which the bucket, particularly the rim portion thereof, is subjected from contact with the bucket cover for substantial service periods. Moreover, the coating is likely to be damaged at the end of the doiiing periods when the packages are removedfrom the buckets, especially if the buckets are removed from their nests and bumped or dropped ona hard surface to loosen the packages. As the metallic base material of the bucket becomes exposed, it is subjected to corrosivea-ttack.
It is an object of the present invention to provide a metallic bucket which-has greater resistance to corrosion. Another-object is toeliminate the necessity-for coating the interior rim surfaces of the bucket. It is another object to provide spinning buckets which are maintained at less cost and capable-of longer service periods. Other objects, features and advantages be apparent from the following description of the invention in which Fig. l is an axial sectionof 'a spinning bucket constructed according to the invention;
Fig. 2 is -a fragmentary axial sectiono'f'a bucket of modified construction; and
'3 is a fragmentary section-of another modmed bucket.
in brief, the bucket of the present invention comprises a body member and a thin *metal sheath'covering at least the interior and top of the rim of the body member including the sh'oulder for seating -a cover. The sheath may also comprise an annular section extending axially within the bucket from the shoulder. The body section is machined or otherwise formed-with a recess such as necessary to fit the sheath within the fin'ished dimensions of the bucket.
Fig. .1 illustrates a bucket having a metallic body-section 5 and a metallic sheath 1 of readily worked, ductile, thin-gauge material having greatencorrosion resistance than the material of the bodysection. The-body secti'on 5 is machined or otherwise formed'to provide surfaces to receive the sheath 1 such that the outer surfaces of the sheath will conform to the dimensions required of the finished bucket. As shown in Fig. 1, the sheath 1 extends from its circumferential boundary at 8 between the ends of the cylindrical cakeforming surface of the bucket, then over the shoulder between the inner cylindrical rim surface and the cake-forming surface to form a seating surface 20 forthe cover !8 of the bucket, then upwardly over a circumferentially extending groove l '5) formed in the rim ofthe body and over the rim 'of the body to an outer circumference 'II thereof. The material from which the sheath is formed is, in a convenient or preferred form, a length of tubular stock of a desired metal. It is inserted into the bucket and worked into conformity with the surface of the body such as by the well-known metal spinning technique. Although not essential, the surface of the body 5 which receives the sheath may be first coated with a cement for establishing adhesive relationship between the sheath and the body. The cement may comprise, for example, thermosetting or thermoplastic resins such as compositions containing condensation products of phenol-formaldehyde, urea-formaldehyde, or alkyd resins, vinyl resins or vulcanizable compositions containing rubber or one of the synthetic rubbers. The sheath may be made to conform also to a plurality of grooves l4 extending upwardly within the rim from the cake-forming surface at 15 to the top edge of the rim at I6. The grooves I l preferably extend slightly below the inner surface of a cover 18 when the cover is properly seated within the bucket so that the grooves are contiguous with the cake collecting region of the bucket. The cover 18 is secured against the seating surface of the bucket at 20 by alock ring 2]. A coating 22 of tough corrosion-resistant resinous material such as one from the group hereinafter recited, is preferably applied to the outer and inner surfaces of the bucket with exception of that of the corrosion-resistant sheath I. Care is taken, however, to carefully coat the surfaces of the sheath and the bucket body 5 adjacent their juncture to forestall possible electrolytic action between the different metals of the sheath and the body.
Preferred materials for the sheaths of buckets used for collecting viscose yarn include tantulum; titanium; a stainless steel designated by SAE number 316 containing approximately 12 to 18 per cent chromium, 10 to 14 per cent nickel, and '2 "to 3 per cent molybdenum; and an alloy containing 55 to 60 per cent nickel, 15 to 20 per cent molybdenum, 6 per cent iron, and per cent tungsten. Such materials in the form of thingauge sheeting or tubing are readily cold worked into conformity with the rim surfaces of a bucket. These materials may be also preformed into sheaths of a desired shape and then pressed and/or cemented into place.
Fig. 2 illustrates a bucket of modified construction in which a lock ring groove is not provided in the rim of the bucket; instead, a cover 24 is peripherally grooved at 26 to retain and support a resilient lock ring 21. The base member or body 30 of the bucket is of metallic material such as aluminum. The body 30 is formed in such a manner, such as by a machining or grinding, to receive the metallic sheath 32 extending from the circumference of the inner surface of the body at 33 upwardly and then radially outwardly to form the seating surface of the bucket and then upwardly over the edge of the flange and downwardly over the exterior of the flange. The flange 35 of the body 30 is completely covered by the sheathing so that the flange may be protected from abrasion and corrosion as hereinafter described.
The bucket of Fig. 2 is coated with a material which is resistant to the materials with which the bucket comes in contact in the operation of collecting yarn. For example, suitable materials for coating buckets used to collect yarn produced by the viscose process are solutions and dispersions containing vinyl resins, fluorinatecl ethylenic compounds, alkyd resins, silicone resins, condensation products of phenol-formaldehyde, urea-formaldehyde and melamine-formaldehyde and others. It is particularly important that the coating material penetrate and seal the seams at the edges 31 and 38 to prevent acid solutions or other electrolyte from entering the joint formed at the interface of the sheath and the body, and producing electrolytic action between the different metals of the body and the sheath. The coating may be applied; if desired, to all surfaces of the bucket including those of the sheath. However, as it is anticipated that the coating will in a short time be worn or abraded from the surface of the sheath, particularly at the seating surface for the cover 24, application of the coating may be restricted to surfaces not covered by the sheath. A high degree of care should be exercised that the coating overlaps the edges of the sheath so as to insure perfect sealing at the seams 31 and 38.
Fig. 3 illustrates another inodification of the invention according to which the rim 40 of a bucket 4| is recessed to receive a metallic annular insert 43. In the practice of the invention, the body portion 44 may be fabricated from an inexpensive and easily worked metallic material such as aluminum; the insert 43 comprises any metallic material which is preferably highly resistant to corrosion under the operating conditions to which the bucket will be subjected. Suitable inserts may be fabricated from tantulum, titanium, or the ferrous alloys hereinbefore described. Other well-known commercially prepared ferrous alloys suitable for fabricating inserts for buckets to be used in spinning viscose yarn are those which contain 16 to 24 per cent chromium, 25 to 30 per cent nickel, 1 to 5 per cent copper, less than 0.1 per cent carbon, 2 to 4 per cent molybdenum, and l to 5 per cent manganese.
A metallic insert 43 as shown in Fig. 3 is provided with a rounded edge 45 which protrudes above the upper edge 46 of the body section 44 to protect the adjacent rim area of the body section, or a coating thereover, from damage or excessive wear. A coating 49 of corrosion-resistant resinous material is applied to surfaces of the body section 44. It may or may not entirely cover the surface of the insert 43 but it is highly desirable that the coating overlaps surfaces of the insert which are adjacent to or meet the surface of the body section, and that it thoroughly covers the junction of the surfaces of the insert and the body section to prevent electrolysis. For this reason, the surface of the insert 43 may be formed with a fillet 48 so that the surfaces of the insert and edge 46 of the body portion join in a smoothly contoured protected area adapted to receive and retain a coating of substantial thickness. An insert such as the insert 43 and a bucket body section may be complementarily formed in any desired manner to effect assembly thereof such as by pressing the insert into place, by heating the rim of the body portion and shrinking it about the insert, by cementing the body portion and the insert together, by joining the insert and the bucket body in threaded relationship, or by keying them together. The insert 43 may be formed, for example, as a forging, or consist of a section of tubing machined to the desired shape. A plurality of escape grooves, such as the groove 5| may be provided for passage of liquid material from a yarn package contained within the bucket. The use of the inserts and sheaths herein described is not necessarily limited to the construction of buckets having metallic bodies. When found advantageous, the metallic sheaths or inserts may be applied to bucket bodies of nonmetallic construction such as those fabricated from a molded material comprising a phenolformaldehyde condensation product mixed with a fibrous material.
While preferred embodiments of the invention have been shown and described, 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.
