Nov. 30, 1937. H. G. BLACK AIR BAFFLE FOR RAYON CAKE DRIERS Filed Jan. 28, 1936 Patented Nov. 30, 1937 UNITED STATES PATENT oFF cs AIR-RAFFLE FOB..RAYON CAKE DRIERS Harold G. Black, Phlladelphim la assignor to Proctor & Schwartz, Incorporated, Philadelhia, Pa., a corporation of Pennsylvania Application January 28, 1936, Serial No. 61,232 6 Claims. (CI. 34-26) 1 gaseous medium are circulated transversely of and across the trucks or racks, substantially axially of the cakes which are hung on pegs or other supports projecting horizontally and laterally from a central support or supports arranged l and extending longitudinally of the truck or rack. In the form of drier and under the process described above the areas of the inside or core openings of the perforated cylinders, spools or cakes are so large that a considerable volume of the drying medium passes directly through the core openings without coming into contact with the yarn wound on the outside of the cylinders,
etc., consequently an excessive amount of drying medium is necessarily required to dry the yarn. The object of the present invention is to deflect a large percentage of the drying medium which normally passes through the core openings of the cakes, so that this deflected medium will pass around the outside of the cakes instead of through the centers thereof, whereby'the deflected medium will contact with the yarn wound on the outside of the cakes.
Aclear understanding of the means for deflecting the drying medium may be had from the following description, together with the illustration of the accompanying drawing, wherein:
Fig. 1 is an end view of a truck or rack with a few cakes of rayon yarn supported thereon;
Fig. 2 is a vertical longitudinal sectional view taken on the line 2-2, Fig. 1;
Fig. 3 is a perspective view illustrating the preferred form of deflector; and
' Fig. 4 shows a modified form of deflector.
As shown in Figs. 1 and 2, the truck or rack comprises a. horizontal base or bottom floor l, a vertically spaced and parallel top or roof 2, comer posts 3, 3 and center posts 4, 4 which latter are arranged in a common vertical plane centrally disposed with respect to the sides of the truck and together with the corner posts 3, 3 are connected at their top and bottom ends to the roof 2 and floor l respectively.
Secured to and extending laterally from the opposite sides of each of the center posts 4 is a series of pegs 5 which in the present instance are each composed of a heavy gage wire or red bent into a U-shape or hairpin form with the legs 6, 8 of each peg welded or otherwise secured to a center post 4.
As shown in the drawing, the center posts 4 5 are rectangular in cross-section and arranged on the truck with the larger dimension of their respective cross-sections extending transversely of the truck and whereby the narrow edge of each post is presented to the flow of drying medi l0 which, as noted above, travels across the trucks and lengthwise of the pegs 5.
Each peg 5 is adapted to support a pluralityof spools or cakes z, and as shown in Fig. 2 the inner diameter of the cake or the cylinder on which the 15 rayon is wound is such that the cakes may be readily slipped over the outer bent ends I of the pegs and onto spaced legs 6, 6 thereof whereby the legs frictionally engage the inner diam-' eters of the cakes a: and support the cakes against free or loose movement on the pegs 5.
As shown in the drawing, the deflectors forming thesubjectof the present inventionare in the form of round discs l0 each of a diameter less than. the inner diameter ll of the cake :0, 2;, whereby an annular space I2 is provided between the outer peripheraledge of each deflector I0 and the inner diameter of a cake :0.
The deflector discs :2: may be placed at any desired point along either or both of each pair of the pegs 5, which are substantially aligned and project laterally in opposite directions from the some portion of a center post 4.
In the preferred form of the invention, the. deflector discs Ill are secured to one or the same 35 side of each and all of the central posts 4 as by welding and each in a position between and .spaced equally from the legs 6', 6 of the pegs 5, v
as clearly shown in Figs. 1, 2 and 3, whereby I the deflector will be substantially concentrically 40 disposed with respect to the inner diameter of any cake or cakes which may be placed on the peg and wherein it may be said that the deflectors are concentric to the axes of the pegs 5, 5 respectively. 5
In Fig. 4, the deflector disc Illa is shown as. being located adjacent the outer or bent end 1 of the peg 5, and provided with ears l3, l3 which are secured to the legs 6, 8 of the peg as by welding.
1 and 2 in particular, it will be clear that air blowing across the truck in-the direction of the arrows in Fig. 1, will pass axially of the pegs 5 and the cakes :c, x which are axially aligned From the above, and upon referring to Figs.
- heat is required to heat the air in condition.-
therewith and thereon, and will enter the inner diameters or cores ll of the cakes. In so doing, a larger part 01' the volume of air passing into the core openings ll of the cakes a: will strike against the deflectors l located therein and which will cause a banking or retardation of the flow of air through the core openings I I, leaving a smaller percentage pass through the annular openings I2 and deflecting the larger percentage around the outside of the cakes :n, to and through the spaces I5 formed between adjacent cakes, which, as shown in Fig. 2, are in staggered relation to each other on the truck or rack.
By this invention, it has been found that a smaller volume of drying medium is needed than has been required heretofore. A smaller volume of air results in a saving in power to maintain circulation in the drier and a smaller amount of Thus it will be seen that while the invention is of a very simple nature and inexpensive to produce and install it results in material savings to the user in the way of power and heat;
1. In a drier for rayon cakes each having a core opening, means for supporting said cakes, means for passing a current of conditioning medium in a direction axially of said cakes and through said core openings, deflectors disposedsubstantially within the core openings of predetermined cakes respectively in planes transverse to the axes of said core openings and of lesser area than the cross-sectional areas of said core openings leaving relatively narrow passages for said medium between the marginal edges of the deflectors and the walls of said core openings and deflecting to the outsides of said cake portions of the flow of said medium which normally passthrough said core openings, and means for supporting said deflectors in said positions relative to said core openings. 1
2. The combination in a rack for drying rayon cakes each having a core opening, a vertical support, a series of pegs extending substantially horizontally from said support for entrance into said core openings to support said cakes, a series of deflectors disposed in planes transverse to the axes of said pegs respectively, the areas of said deflectors being less than the areas of the core openings of said cakes respectively, and means for supporting said deflectors in positions relative to said pegs to form relatively narrow passages for conditioning medium moving in a direction axially to said pegs between the marginal edges of said deflectors and the walls of said core openings respectively when said cakes are mounted on said pegs.
3. The combination in a rack for drying rayon cakes each having a core opening, a support including a peg comprising a pair of substantially parallel relatively spaced legs adapted to pass into said opening for-holding the cake, and a deflector between said legs and extending transversely of said opening and deflecting around the outside of the cake-drying medium which normally would pass through said opening.
4. The combination in a rack for drying rayon cakes each having a core opening, a support comprising a vertically disposed bar of rectangular cross-section arranged with the greater dimension extending in the direction of flow of drying medium, a peg comprising a pair of substantially parallel relatively spaced legs secured to said rectangular bar and projecting laterally therefrom and adapted to pass into saidopening for holding the cake, and a deflector between said legs and extending transversely of said opening and deflecting around the outside of the cakedrying medium which normally would pass through said opening.
5. The combination in a rack for drying rayon cakes each having a core opening, a support comprising a vertically disposed bar of rectangular cross-section arranged with the greater dimenf sion extending in the direction of flow of drying medium, a peg comprising a pair of substantially .parallel relatively spaced legs secured to said cakes each having a core opening, a support including a peg comprising a pair of substantially parallel relatively spaced legs adapted to pass into said opening for holding the cake, and a deflector comprising a circular disc disposed between said legs concentric to said opening and extending transversely of said opening and deflecting around the outside of the cake-drying medium which normally would pass through said opening.
