Definitions

  • This invention relates to an apparatus for the drying of packages of rayon and similar; textile yarns of threads and more particularly to an apimprovements over those disclosed in U. cember 16, 1941, reference to which is hereby made.
  • U. S. Patent No. 2,266,375 describes and claims a method of drying rayon packages under a'controlled vacuum in a closed container to effect the drying of the rayon at lower temperatures than would otherwise bepossible, the drying of the packages proceeding from the inside to the outside thereof.
  • An apparatus for practicing the 'method is also described and claimed in the said ages may be assembled on patent.
  • the container is provided with a number of heating cylinders extending inwardly from one end wall thereof.
  • the cylinders are each open at their fixed ends to permit the circulation of a'heating medium therethrou-gh, at their unsupported ends to confine the heating medium to the interiors thereof.
  • Rayon packthe cylinders in any convenient manner, e.
  • each of the tubes is of such diameter with respect to the raying of rayon in those on packages that it is sufficiently small to permit complete contraction of'the rayon in the packages during drying.
  • the patentees intend that a of apparatus made in Another object of the invention is to provide a drying apparatus having rotatably'mounted loading tubes on those heating cylinders positioned adjacent or near the shell of the container so that the loading tubes supporting the packages exposed to radiation of be rotated at intervals during drying.
  • This invention also contemplates the provision of a drying apparatus having a plurality'of parallel rotatably mounted loading tubes arranged within a container adjacent or near the shell thereof in which the tubes are geared together for simultaneous rotation, and in which exterior means are provided for effecting partial rotation of the tubes.
  • Figure 1 is a side elevational View of one form accordance with this invention, the container being partially broken away to show the mechanism for rotating the loading tubes; and
  • I l Figure 2 is a transverse ectional view through the apparatus illustrated in Figure 1, showing the arrangement of the heating cylinders and the loading tubes with gears fon rotating the packages positioned adjacent the cylindrical shell of the container.
  • Gearing designated generally at l! is provided rotating the tubes.
  • An apparatus for drying rayon packages having thread-free centers which comprises a container, means for hermetically sealing the same, a plurality of imperforate heating cylinders fixedly arranged in the container, loading tubes adapted to support rayon packages thereon and to removably fit over the cylinders. means on the loading tubes near the shell of the container for rotating the loading tubes at will durfor driving the gears.
  • Gearing l1 includes a spur gear I8 which meshes with the lowermost gear iii of the series. Gear i8 is keyed to counter shaft l9 which shaft is suitably supported in bearings fixed on plate by means of standard 2
  • Plate 20 constitutes a cover for an opening 22in the shell of the drier H).
  • a bevel gear 23 is mounted on the end of shaft l9 remote from gear I8. Bevel gear 23 meshes with a bevel gear 24 mounted on vertical shaft 25.
  • Shaft 25 extends down through a stumng box hearing assembly 28 and plate 20 so that driving of the gear train may be efiected from outside of the vacuum drier. Any suitable means for rotating shaft 25 may be employed such as a ratchet lever, wheel or crank (not shown). Shaft 25 may be operated either manually or automatically. While container [0 may be lined with insulating material as shown in the said patent the lining is not essential when the loading tubes adjacent the container are constructed for rotation as described.
  • rayon packages are first assembled on all of the loading tubes H and the tubesswith the packages thereon are deposited over the heating cylinders l I. It is to be understood that those loading tubes H to which the gears. l6 are secured are deposited upon the heating cylinders of the outer annular row or rows of cylinders whereas the normal tubes are deposited upon the inner cylinders. At this stagethe drier is hermetically sealed and evacuated to a high vacuum. A heating medium is circulated through the closed cylinders in the manner described in U. S. Patent No, 2,266,375 so that the packages on the tubes are dried progressively from the inside to the outside.
  • An apparatus for drying rayon packages having thread-free centers which comprises a container, means for hermetically sealing the same, a plurality of imperforate heating cylinders fixedly arranged in the container, loading tubes adapted to support rayon packages thereon and to removably fit over the cylinders, gears on the inner ends of the loading tubes near the shell of the container for rotating the loading tubes at will during the drying operation, means for driving the gears from the outside of the container and means for evacuating the container.
  • a drying apparatus for rayon packages having thread-free centers comprising, an annular chamber provided with an open end, a removable door for closing said chamber, sealing means between the door and the chamber, annularly arranged rows of parallel imperforate heating elements extending inwardly parallel to the horizontal axis of the shell of the chamber, loading tubes for receiving packages of rayon thereon, one of said tubes fitting over each of the heating elements and closely engaging the same, said loading tubes that are mounted on the heating elements of the outer annular rows each being provided.
  • a drying apparatus for rayon packages having thread-free centers comprising, an annular chamber, parallel imperforate heating elements extending inwardly from a plate constituting the end wall of the chamber, loading tubes for holding packages of. rayon, said tubes being detachably positioned upon the heating elements and being rotatably mounted thereon, the tubes each spur gear fixed to its end adjacent the plate, said gears on the tubes meshing to form a continuous gear chain, means for rotating the gears of the train to eifect the rotation of each of the tubes with the packages thereon and means for evacuating the chamber.
  • a drying apparatus for rayon packages having thread-free centers comprising, an annular chamber, means for evacuating the chamber, rows of parallel imperforate heating elements extending inwardly parallel to the horizontal axis of the shellof the chamber, loading tubes for receivingpackages of rayon thereon, said tubes being snugly mounted upon the heating elements, a series of the loading tubes each being provided in position, within the chamber for meshing with one of the spur gears of the chain when the carrier tubes are in operative position, a.
  • a drying apparatus for rayon packages having thread-free centers comprising, an annular chamber provided with an open end, a sealed door for closing said chamber, annularly arranged rows of parallel lmperforate heating tubes extending inwardly parallel to the horizontal axis of the shell of the chamber, two sets of loading tubes for receiving packages of rayon thereon, the loading tubes of each set each being removably positioned over and snugly engaging one of the heatingtubes, the loading tubes that comprise the set mounted on the respective heating elements of the outer annular rows each being provided with a spur gear fixed to its inner end, the spur gears on said tubes meshing to form a continuous gear chain, -a gear fixed in position within the chamber and meshing with one of the spur gears of the chain, means for rotating the said gear which in turn 6 effects the rotation of each of said loading tubes of the outer rows together with the packages thereon and means for evacuating the chamber.
