UNITED STATES PATENT oFFlcE WINDING REEL Application January 16,'1933, Serial-No. 652,089 Renewed June 15, 1939 30 Claims.

, This invention relates to a winding reel for the manufacture of thread or the like, as, for example, artificial silk thread. The invention has to do with a reel of this type by and upon which the thread or the like is Wound in a manner permitting it to he subject-ed in a relatively long length to any processing operations to which it may be desired to expose it. The Winding reel of the present invention may be regarded as an improvement upon the type of reel shown and described in a prior application for Continuous spinning machine, Serial No. 651,404, led January 12. 1933, to which reference may be had if desired. It may also be treated as an improvement upon the severa-l types of reels respectively shown and described in United States Patents Nos. 34,494, 1,052,125, and 1,983,221.

An object of the present invention is to provide a simple, improved reel of the character described consisting of two like members, both of rigid form, closely associated in the sense that they are more or less superimposed upon each other or occupy substantially the same space, but having their axes displaced with relation to each other.

for the purpose of advancing, turn by turn, thread or the like led to it, all with dependable uniformity and regularity of action, Without harmful effect upon the thread or the like, and in a manner to avoid errors in operation as the result of wear and tear in the apparatusf A further object of the invention is to provide a reel of this kindgwhich can be made in any desired length within reasonable limits; which can advance one thread or thread-like article or. if desired, a plurality of threads or thread-like articles, the several threads or thread-like articles being kept separate from each other; and in which the mechanism need embody only .relatively simple bearings. and driving means, and other parts.

o Further objects of the invention are in part obvious and will in part appear more in detail hereinafter.

In the drawings, Fig. 1 represents a plan of one form of reel embodying the invention; Fig. 2

is a corresponding explanatory diagram; Fig. 3

is a sectional elevation, more or less diagrammatic. illustrating three reels coordinated into a machine and cooperatively rela-ted to a spinning device: Fig. 4 is an elevation of the reels, as seen from the left in Fig. 3; Fig. 5 is an end elevation of the reel from the right in Fig. l; Fig. 6 is a corresponding explanatory diagram; and Fig. '7 is a sectional elevation of the reel on substantially the line 1 -'1, Fig. 5. While the invention may be employed under any conditions making it desirable to provide a reel capable of advancing thread or the like or of storing a considerable length of thread or the like, so as to serve as a store device therefor, the invention is illustrated in the drawings and will 5 be described hereinafter as employed as an element of a continuous spinning machine for the production of artificial silk thread, particularly a machine .of the kind in which a separate step of the process is yperformed upon the thread on each 10 of `a plurality of reels to which the thread is led in succession, all as generally described in the prior application above referred to. It is obvious,

however, that the reel is not limited in its usefulness to continuous spinning machines for the 15 manufacture of artificial silk thread, but may to advantage be employed, -either alone or in association with otherreels, in a-wide variety of machines of Wholly different types.

While the invention may be usedwith any of 20 the Well known processes for producing articial silk thread, such as the cuprammonium, cellulose a-cetate, cellulose nitrate and the viscose processes, it will for convenience Ibe described only in connection with the practice of the viscose 25 process. Referring first to Figs. 3 and 4, trough I is illustrated as containing a coagulating bath 2 intovwhich the viscose is extruded through the usual spinneret 3, the multiple filament thread 4 being led through suitable guides 5 to the rst of a series of rotating

reels

6, 6a, 6b, each of which is designed to receive the thread, form it into a series of helical turns spaced at relatively short intervals, and advance it bodily along the reel toward its opposite end'to a take-off point from 35 which the thread is led to the next reel. It is of course understood that on each of said reels a different step of the process of manufacture is performed upon the thread until the latter iinally emerges in completed or partially completed form ready to be gathered upon a collecting device. The present invention has to do with the specic form of the reels employed'.

In the arrangement shown in Figs. l, 5 and '7, the reel comprises two

reel members

1, 8, each of 45 which constitutes a self-contained rigid structure having its periphery, which v is of substantially circular cross section, defined Iby a series of longitudinally extending parallel bars or bar-like members.

the same space. Each reel member comprises not only the longitudinal bars aforesaid, but a supporting structure which may be of spider, wheel or disc form with a'central hub. The supporting structures of the two reel members are sufficiently spaced longitudinally from each other so that said members can occupy substantially the sa-me space, as stated.

In the arrangement shown, the reel member 1 is provided with a supporting structure consisting of a spider or disc 9 secured to a shaft I0, as by the set screw II, said spider or disc 9 carrying at its periphery a series of longitudinally extending bars I2 which extend longitudinally in both directions from the spider or disc 9, the latter being a spider or disc I3 carrying a series of like longitudinally disposed bars I4 on its periphery, but in this case the spider or disc is shown as disposed at one end of the reel member andthe bars project longitudinally in one direction only from the spider or disc, the arrangement being such that the bars of the two reels lie side by side and are coextensive longitudinally. Reel member 8 is also shown as a true cylinder in. the sensel that the outer vedges or surfaces of its bars form elements of a cylindrical surface, but it is not coaxial with the shaft I0. The bearings for its spider or disc I3 are carried by a portion of the machine frame I5 and are so arranged that the axes of the two reel members are displaced from each other in two respects, as will hereinafter appear.

First, the axes of the two reel members are displaced laterally from each other by a uniform amount along the full length of the reel and, second, the axis of one reel member is canted to a-n inclined position with reference to the axis of the other reel member. The axes of the reel members are thus in skew relation to each other. In other words, looking at the diagrams, Figs. 6 and 2, which greatly exaggerate conditions, reel member 'l is assumed to be coaxial with the shaft I0 and the reel member 8 has been displaced laterally with relation to member 'I until the reel members are entirely separated from each other, as shown in Fig. 6, and reel memlber 8 has been canted to an inclined position with relation to member 1, as shown in Fig. 2. As amatter of fact, in a reel of say ten inches in diameter, the parallel displacement may amount to say oneeighth of an inch and the cant shown in Fig. 2 may amount to a matter of only a very degrees, say seven-sixteenths of an inch in a total reel length of forty-eight inches.

Thus in the preferred embodiment of the invention the axes of the reel members may be dened in geometrical terms as represented by skew lines.

The number of bars in the two reel members may vary, but, other things being equal, the total number of bars should be as large as possible consistent with proper construction, operation, etc. As shown in Fig. 5, the bars of the two reel members preferably alternate with each other. Also, one of the reel members; to wit, reel member I in the form shown, serves as a driving member and the other, reel member 8 in the form shown,

serves as a driven member. Member 8, as shown in Fig. 7, is journalled upon a bearing of tubular form carried by the fixed frame I5, which bearing is so disposed as to be displaced from the axis of shaft I0 in the two particulars above mentioned.

With this arrangement, when shaft IIJ is driven, the two reel members rotate together or as a unit, one driving the other by bar to bar engagement. The lateral displacement of the axes of the two reel members causes the bars of the driving reel member 1 to project outward beyond those of the other member 8 during a part of a complete rotation, say through the lower 180 in Fig. 5, and the bars of the driven member to project outward beyond those of the driving member through the other half of the complete rotation, the upper 180 in Fig. 5. This back and forth relative radial motion of the two sets of bars makes possible a transfer of the turns of.thread from one reel member to the other. Furthermore, the canted disposition of the driven reel member 8 produces bodily advance of portions of the thread which are carried by it during that portion of the complete rotation when its bars are supporting the thread, to wit, during the upper half of the complete rotation, as shown in Fig. 5.

The total effect is to cause a thread led to one end of the reel to be wound upon the reel in substantially helical form, turn after turn, with the succession of turns bodily advanced toward the far end of the reel. In this manner a thread led to the reel can be stored upon it in the form of a large number of very closely spaced turns, even as many as fifty to two hundred turns, and if the reel is of relatively large diameter, say ten inches, it is possible to store upon it a very long length of thread, even as much as five hundred feet. 'I'hus if a bath of treating liquid is showered upon or otherwise applied to the reel, a given portion of the thread will be subjected to said bath for a material length of time, depending upon speed of rotation, number of turns and lead of the thread helices, etc.

Obviously, the amount of lead or the spacing of turns of thread from each other depends upon the amount of cant, in other words, the second factor in the displaced relation between the two reel members before referred to and by varying the amount of such cant any desired lead may be obtainedwithin limits.

The skew relationship of the axes of the reel members characterizing the preferred ambodiment of the invention may be arrived at in various ways. If it is assumed that the final relative positions of the reel members are reached by lrst laterally displacing them and then turning them about an imaginary axis radial to the shaft I0, it will readily be perceived that such axis may be located at any point along the length of the reel as a whole, or, in other words, at any one of a number of points, three of which have been marked X, Y and Z in Fig. 1. In the reel shown, the cant has been accomplished by twisting reel member 8 about an imaginary radial axis at the point Y and the cant is therefore balanced or equal but in opposite directions on opposite sides of the axis Y longitudinally of the shaft. If, however, the inclination is accomplished by canting reel member 8 around axis X or axis Z, all of the angular relationship will be on the same side of such axis. Twisting about axis Y produces a reel which is more or less hour-glass in shape, while twisting about axis X or axis Z produces a reel which is more or less conical in shape.

ber. In other words, referring to Fig. 2, when the canted reel member is twisted or turned clockwise in Fig. 2, as shown in full lines, they turns of thread will be bodily advanced toward the right, but if the canted reel member is turned counterclockwise to the position indicated in dotted lines, Fig. `2, the thread turns will move to the left. By proper organization of the reel members on successive reel units the thread may be led back and forth in the manner shown in Fig.,4, travelling to the right on reel 6, to the left on reel 6a, to the right on reel 6b, etc.

In the arrangement shown in Figs. 1 to 7 inclusive, each reel is designed to support a single thread in the proper number of turns thereof but if desired the reel may be made long enough to support a plurality of threads simultaneously led to it.

Of course, since the reel is drenched by the bath `of liquor showered upon or otherwise applied to it for treatment of the thread, it is obvious that the reel and all of its parts, including supports, etc., should be made of materials Which are not laffected by and do not aifect the bath liquors, as will be readily understood. In general, chemical-resistant materials will be employed throughout with the possible exception of reels used only for washing, drying or like operations not involving the use of corrosive reagents. Obviously, acid resistant materials, Whether metallic or non-metallic, willl be used in reels coming into contact with acids, as, for example, in reels used in conjunction with the coagulating bath in the viscose process of manufactur'ing artiiicial silk thread.

While in the foregoing description frequent reference has been made, for purposes of i1- lustration, to the produ-ction of artificial silk thread, it is to be understood that the winding reel of the present invention has many and varied uses not in any Way connected with artificial silk thread or, for that matter, with the various steps involved in the actual manufacture of thread of any particular kind. It is obviously vcapable of use in the manipulation and/or processing of thread quite apart from the method of its manufacture, regardless of whether .the

thread so manipulated or processed is of natural or synthetic origin. As a matter of fact, the,

winding reel of the present invention is suitable for use not only in conjunction with the manufacture, manipulation and processing of thread, but also in conjunction with the manufacture, manipulation and processing of other articles that, speaking in the broadest sense, are of generally thread-like character. I'hese articles it is intended to include, together with thread, Within the scope of such generic expressions as thread or the like and thread-like article as used in the specification and claims hereof.
