Definitions

  • the present invention relates to spinning buckets such as are used in the manufacture of rayon.
  • Spinning buckets of this type are required to revolve at high speeds, for example, speeds of the order of 10,000 R. P; M. This means that the buckets are subjected to centrifugal stresses of a high order and to withstand such stresses must be of uniform construction in order to give the greatest strength for a given weight and thickness of material.
  • the bucket is closed with a cover. It is required that while running, the cover be held firmly in place in a manner such that the axial pressure from the rayon cake being wound up inside the bucket will not raise the cover. However, when the bucket is stopped, it is desirable that the cover becapable of being removed readily.
  • the object of my invention is to provide an improved spinning bucket and cover therefor wherein the cover may be easily inserted and removed when the bucket is not running'and is locked firmly in place when the bucket is runing; and wherein at the same time, the locking means for the cover does not require the provision of a relatively deep groove at the rim of the bucket for the reception of a locking ring.
  • Fig. 1 is a side elevation, partly in section, of a bucket and cover embodying my invention
  • Fig. 2 is a plan view of a portion of the cover and bucket
  • Fig. 3 is an enlarged view showing the locking means for the cover.
  • 1 indicates a rayon spinning bucket of any suitable type.
  • the bucket may be of the molded type. It may be formed of textile fibres united by an artificial resin, such as phenolic condensation product, and reinforced by a winding of wire as indicated at 2.
  • it may be a bucket such as that disclosed in the application of Bergman, Serial No. 622,272, filed July 13, 1932.
  • the usual drain holes for the bucket are indicated at 2a. 4
  • the upper edge of the bucket is provided with a ledge 3 spaced from the top surface of the bucket and forming a seat for a cover.
  • seat 3 the upper portion of the bucket is offset outwardly somewhat but the wall of the bucket is maintained at substantially the same thickness.
  • a shallow annular groove 4 adjacent the plane of the top of the bucket is a shallow annular groove 4.
  • the rim of the bucket is not weakened by a relatively deep groove for a cover looking arrangement as is the usual practice.
  • the cover comprises a bottom wall 5 having a central opening 6, a side wall 7, and a flange 8.
  • Side wall 7 fits loosely within the upper end of bucket 1, the bottom of the cover resting on seat 3.
  • Side wall 7 is provided with a bead 9 which fits snugly into groove 4.
  • Flange 8 and side wall 7 are provided, with a plurality of slots 10 which extend down substantially to bottom wall 5. The slots serve to give a certain amount of flexibility to the flange and side wall.
  • groove 4 is provided with an angular sloping upper surface or wall 11 with which the upper surface of bead 9 engages.
  • Surface 11 may have, for example, a slope of the order of with respect'to the horizontal.
  • the arrangement is such that the distance X from the bottom surface of the cover to the center line of bead 9 is greater than the distance Y from the surface of seat 3 to the lower edge of surface 11.
  • centrifugal force which tends to expand side wall 7, causes bead 9 to press against surface 11, thus forcing the cover downward on its seat.
  • centrifugal force causes the bucket cover to be firmly pressed against seat 3 and to be firmly locked in position by bead 9.
  • flange 8 When the cover is in position, flange 8 is spaced slightly from the top surface of the side wall of the bucket as is indicated at 12 in Fig. 3. This enables a suitable tool to be inserted under the flange to assist in lifting the cover from the bucket.
  • the cover has the advanta e that the centrifugal load transmitted by it to the rim of the bucket is a minimum, and since the rim of the bucket is of substantially uniform thickness and without a deep groove such as found in the "conventional type of rayon spinning bucket, there is provided a construction wherein the rim of the bucket is capable of withstanding high centrifugal stresses.
  • a flange surrounding the bucket cover which is spaced from the top surface of the bucket side wall when the cover is in place.
  • a bucket cover for a rayon spinning bucket having a bucket cover seat and a groove spaced '-from the seat, comprising a bottom wall, a side greater than the distance between the seat and the center'of the groove of the bucket with which the cover is to be .used.
  • a bucket cover for arayon spinning bucket having a bucket cover seat and a groove spaced from the seat, comprising a bottom wall, a side wall and a .flange, the side wall being provided with a bead the center of which is spaced from the lower surface of the bottom wall a distance greater than the distance between the seat and the center of the groove of the bucket'with which the cover is to be used, and with spaced slots to lend flexibility thereto.
