SPINNERET COUPLING Filed ma 51, 1935 1 15 f" 7 00/ I. (Zap/rm, I
Patented Mar. I 31, 1936 UNITED- STATES PATENT foFFi-cE 2,036,087 SPINNERET coUrLmG Paul A. Chapman, Elizabethton', Tenn, :issignor to North American Rayon Corporation, 'New York, N. Y., a corporation of Delaware Application May 31, 1935, SerialNo. 24,275 Z Claims. (Cl. 285-182) The present invention relates to spinning nozzles and particularly that class of the same which are utilized for forming filaments from solutions of cellulosic origin in which the spinning solution is forced under pressure through a perforated spinneret into a precipitating solution.
In the spinning of artificial silk it frequently happens that the spinning nozzles must be changed either due to the partial clogging thereof, or, as may be, the total stoppage of the solution therethrough due to impurities in the spinning solution being of a particle size too large to go through the small spinning orifices. On other occasions, as when different devices are '15 to be spun on the machine, an entire change of the spinnerets' is necessary, in order that spinning nozzles may have the proper hole size. Whenever the aforementioned happenings occur it is essential that the change of spinnerets be 2,0 accomplished as quickly as possible inasmuch as it would be inconvenient and dangerous to the quality of the silk to be spun should the spinning solution be cut oil's It is therefore necessary that the spinnerets be attached to the supply pipes in a. manner which will allow the quick exchange of spinnerets and yet will withstand the high'pressure of the spinning solution.
One object of the present invention is to devise a means for quickly and easily attaching spinnerets to. the spinning pipes.
Another object of the present invention is to devise a construction for attaching spinnerets to spinning pipes which may be easily cleaned.
Still another object of the present invention is to devise an attaching device for spinning nozzles which is of simple construction, inexpensive to manufacture, and of a durable nature.
- These and other objects will in part'become obvious and in part be pointed out hereinafter. To the attainment of the aforesaid objects and ends, the invention consists inthe novel features of construction and in the combination, connections and arrangement of parts, hereinafter more fully described, and then pointed out in the following specification and appended claims. When taken in conjunction with. the attached drawing, in which:'
Fig. 1 is a plan view of one form of the spinneret attaching device; a so Fig. 2 is a sectional view taken on the line 2-2 of Figure 1; 1
.F'ig.3isaplanviewofamodifledfonnof the invention;
' Fig. 4 is a. sectional view taken on the line 4-4 v 55 of Fig. 3;
Fig. 5 is a. plan view of another modified form I of the invention; and r Fig. 6 is a sectional view taken on the line- 6--6 of Fig. 5.
In the drawing, in which like numerals of g reference indicate like parts, I refers to a. tube or pipe through which the spinning solution flows. The pipe I has a. flanged portion 2 which fits within the counter bore 32nd axially coincides with the bore 4 of the coupling head 5. m
The spinneret nozzle '6, through which the spinning solution is injected into the coagulating bath, is usually formed-in the shape of a cup consisting of a cylindrical portion 1, one .end of which'is provided with an annular flange 8 and 5 the other end of which forms the face 9 or draw plate. The face 9 is provided with the usual spinning holes or orifices through which the spinning solution is forced.
The flange 8 of the spinning nozzle 6 rests 2g against a gasket I0 positioned against-a seat I I formed by the counter bore 3 in the coupling head 5. r v
Another gasket I2 is positioned between the flange 8 of the nozzle 6 and the flanged portion 25 2ofthepipel. I
A wedge member I3 is slidably mounted in a slot I4 of the coupling head 5 and has a longi tudinal slot l5 formed in the center thereof through which the pipe I extends. 30
The wedge member I3 is .tapered and when pushed in one direction forces the flange 2 inwardly against the gasket l2 and thereby holds the coupling head 5 thereby preventing loss or 45:
misplacement thereof.
with the use of a coupling head such as described above the changing of spinncrets is' eatly facilitated and done withfar greater dispatch than heretofore in the art.
Referring again to the drawing and particularly to Figs. 3 and 4, in which is illustrated a modified form of coupling head, like numerals of reference will be used for equivalent parts of Figs. 1. and 2 with the exception. that the letter 65.
the gaskets l and l2 and against the seat a will be added thereto. The spinning nozzle and spinning pipe will bear the same numerals as before.
In this form the flanged portion 2 of the pipe I fits within the coupling head 5 and compresses the flange 8 of the spinning nozzle 6 between ll of the counter bore 3 the same as in the preferred form of the invention when wedged thereagainst.
In this form the wedge l3 comprises a forked shape member, the opening l9 between the forked extensions being the equivalent of the slot l5 of the first form. The forked extensions 20 are tapered and extend through slots hi -Hi of the coupling head 5 and when forced inwardly against the flange 2 act to seal the spinning nozzle 6 in position. The wedge I3 in this form must be fully removed in order to withdraw the coupling head 5 from the spinning pipe flange 2 thereby differing from the preferred form. In order to facilitate the removal of the wedge I 3 from the coupling head 5 an extension 2! is provided with an opening 22 formed therein through which a tool may be inserted if necessary.
In Figs. 5 and 6 of the drawing is illustrated another form of the invention. In this form equivalent parts will have the same numerals but with the letter b added thereto.
The coupling head 5 in this instance has an annular groove 23 formed therein and a slot 24 connecting the groove 23 with the outer periphery of the said coupling head 5*.
The wedge member l3 comprises forked extensions l8 having beveled ends 25, the opening between, through which the pipe I, extends is indicatedat I9.
The spinneret flange 8 is compressed, as in the other forms of the invention, between the gaskets I2 and Hi when the wedge l3 is inserted and bears against the flange 2 of the spinning pipe I.
The wedge I3 is inserted in the slot 24 forcing the flange 2 against the gasket 12 in the same manner as in the other forms of the invention and as shown in the dotted line position then turned to the full line position shown in Fig. 5
of the drawing thereby looking it in position against an outward pull.
The wedge I3 also has an extension 2| and an opening 22 formed therein to facilitate the removal of the wedge Ii! from the coupling head 5.
From the foregoing description, taken in connection with the accompanying drawing it is thought the complete construction, operation and advantages of the invention will be clear to those skilled in the art to which it relates.
It is to be understood that the forms of the invention, herewith shown and described, are to be taken as preferred examples of the same, and that various changes in the size, shape and arrangement of parts may be resorted to, without departing from the spiritof the invention, or the scope of the appended claims.
Having thus described the invention as required by the patent statutes, what is claimed is:
1. In a device of the character described, the combination of a coupling head open at both ends and having an internal seat portion formed at one end thereof, a flanged spinneret fitting within said coupling head, a supply pipe having at its end a flange and extending into said coupling head, said coupling head having an internal annular groove formed therein and a slot in the side thereof, and a forked wedge member removable from said coupling head and inserted through said slot and into said groove whereby the said wedge, member bears against said pipe flange to hold said spinneret flange between said seat and said pipe flange, said wedge member being rotated in said slot whereby a locked rela tion between said coupling head and wedge member results.
2. In a device of the character described, the combination of a coupling head open at both ends and having an internal seat portion formed at one end thereof, a flanged spinneret fitting within said coupling, a supply pipe having at itsend a flange and extending into said coupling head, said coupling head having at its other end an internal seat portion and a slot in the side thereof, and a forked wedge member removable from said coupling head and inserted through said slot and into said seat portion whereby the said wedge member bears against said pipe flange to hold said spinneret flange between said first mentioned seat portion and said pipe flange, said wedge member being rotated in said slot whereby a locked relation between said coupling head and wedge member results.
