6 Claims. 1
r This inventionrelates to apparatus used in the mot spinning of artificial filamentary material and. particularly to a closure for a spinning buck- =et compartment. I
.In conventional pot spinning processes, the formation of crystalline materials orother solids formed by the crystallization of soluble components of the liquid materials carried into the spinning compartment by the filamentary material collected therein is prevented by spraying water or other solvent into the compartment. Regardless of the manner in which the liquid 'is supplied to the compartment, the rapidly moving-surface of the bucket and other parts -con .nected therewith, and the air currents resulting from-such rotation, whip the sprayed materials o: any air-suspendable matter about the compartment in an uncontrollable manner. A certain portion of such materials are unavoidably directed into the aperture provided for a spinning funnel stem through the spinning bucket cover. Reduction of the pressure of the atmos phere within the bucket by centrifugal action increases the tendency for material to be drawn into the bucket through the aperture. Moreover, any liquid which is splashed on the stem of the funnel is promptly drained into the interior of thebucket.
Itisan object of the present invention to prevent the-introduction of unwantedsolid or liquid materials into the interior of a spinning bucket *ifrom areeion exterior thereto to thus avoid contam-mating the filamentary product and altering its physical and dyeing properties. .A further object is to provide apparatus of simple con struction which may be readily applied to conventional equipment without appreciable ex- .pense. Other objects, features and advantages cf the invention will be apparent from the following description of the invention and the accompanying-drawings in which Fig. l is a bottom view of .a spinning bucket compartment closure according to the invention; and
Fig. 2 is a view partially in section illustrating elements of a spinning bucket compartment and v the closure of Fig. .1 sectioned along line II--II. Briefly, the invention comprises a lid or a cover for the spinning compartment or nest provided with a flange extending axially from its under surface into close proximity to the surface of a spinning bucket cover to hinder or prevent parti'cles or droplets suspended within the compartmen't from entering the bucket through the central aperture of the bucket cover especially by wayof the funnelstem-exterior. I Fig. .1 illustrates an annular spinning compartvmentcover 4 having as a principal feature .of the invention an annular flange 5 extending downwardly from the lower surface 7 of the cover.
2 The flange 5 may be, but 'is not necessarily, con centric as shown with respect to an aperture 9 through which the stem IQ of a'spinning funnel extends during operation o'f'the spinning equipment. The length as measured in an axial direction of the flange 5 depends upon the distance between the under surface of the compartment cover and the top surface of the spinning uck'et cover. In order to efficiently prevent th entering of unwanted materials that originate within the compartment into the spinning box, the flange is preferably extended to within a half inch of the top surface of th bucket cover [2.
When the flange has an inner diameter of approximately three inches and its lower edge 'extends within a half inch of'thebucket cover 12, it is practically impossible for "air susp'ended material to directly reach the aperture H of the "spinning box cover or the surface of the funnel stem Ill. The outer diameter "of the portion of the flange '5 nearest the bucket cover 12 is such that it entirely encompasses the central aperture of "the bucket cover; the largest outer diameter permitted should be slightly less than the inside diameter of the rim of the bucket, i. e.,"a diameter which permits safe clearance between the bucket and the flange'during operation. As shown in Fig. 2, the flange 5 extends approximately to the upper plane of the bucket riin'when the bucket "is recessed to receive a cover below the end surface of the rim. Preferably, the flange should extend below the level of the top edge of the bucket rim.
A liquid may be introduced into the compartment by a means such as the spray nozzle It shown in Fig. 2. The droplets of liquid "come into contact with the rotating bucket surface and the turbulent atmosphere of the compartment. A portion of the spray during erratic and violent movement falls upon the outer surface 14 of the flange and drains in the manner shown to the surface of the bucket cover. It is centrifugally forced by rotation of the bucket to a region radiall-y beyond the bucket periphery. The flange 5 in this manner actually promotes the collecting ofliqu'id and the depositing of it on the surface of the adjacent bucket cover. The increased amount of liquid received by the bucket :co'ver appreciablyincrea-ses the cleansing of the bucket cover and portions of the rim of the bucket of soluble materials ejected from the filamentary material within the bucket.
The cover 4 may be constructed according to conventional stamping 'or molding procedures. If desired, the flange 5 may extend from the cover in a direction normal to its under side to facilitate the forming thereof. Such covers may 'con 'sist of a corrosion-resistant metal, or a thermoplastic or thermosetting resin which is resistant to the acids and other materials associated with the lock-lid or cover 4, depressions 6 are molded 7 into the cover 4 and have extended walls 8 which form pockets (or protrusions when viewed externally which overlap the edge of th aperture) into which the fingers may be inserted to manually manipulate the lid through th small angle of rotation required when looking it into or removing it from the aperture in the top wall El of the compartment. The periphery of the aperture is appropriately notched along diametrically opposite portions to permit insertion of the cover until the periphery is engaged by the radially extending rim or flange [8. An annular flange 3 extending parallel with the axis of the cover from the outer marginal section of its lower S111:-
face may be provided to position the cover within the aperture of the compartment as Well as to provide desirable reinforcement of the cover, especially when the cover is molded in thin sections.
While a preferred embodiment of the invention has been shown, 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.
