13 Claims.

This invention concerns a novel form of winding reel.

More particularly, the invention relates to a winding reel comprising a plurality of sets-oi longitudinally extending interdigitating bar members, usually, but not necessarily, two in bers is rotable about its own axis, the individual bar members projecting at any given time are necessarily constantly changing, resulting in the course-of any given revolution of the reel as a whole in the transfer from one set of bar members to the other of the material, such, for example,

as thread or the like, wound on the reel. The

bar members of at least one set are adapted to move lengthwise of the reel while carrying the thread or the like, wherebythe thread or the like is caused to advance lengthwise of the reel,

during rotation thereof, in a plurality of spaced,

generally helical turns.

The present invention provides a reel of the above type of cantilever construction, the term cantilever being intended to express the thought that the reel is supported and driven from one end only.- The other end of the reel may thus be left wholly unobstructed permitting ready access to the reel for manipulation of the material wound thereon, inspection, adjustment, etc.

' Reels of the above type may be adapted to store a relatively long length of thread or the like in a small space in a plurality of spaced generally helical turns and may therefore be con- 7 veniently e ployed in the continuous processing of thread or the like. Cantilever thread storage reels, such as that provided by the present invention, may be employed to particular advantage for such purposes, since they lend themselves to disposition in arrangements in which, by virtue.

of their open ended construction, threading up and other manipu ation of the thread or the like stored on the reels, inspection, replacement, repair, etc., are very greatly facilitated.

The cantilever reel illustrated as embodying the invention is of a type comprising a rigid, gen-v erally cylindrical set of longitudinally extending bar members having alternating therewith the bar members of a non-rigid generally cylindrical set of otherwise similar bar members. The bar Inasmuch as each set of bar mom-- member of the non-rigid set are connected to at least one, and preferably two or more, actuating members rotatably mounted about axes laterally offset from and inclined to the axis of the rigid set of bar members. Rotation of the 5 reel causes thread or the like to wind on the reel, the oifset relationship of the axes of the two sets of bar members causing the thread or the like to be transferred from one set of bar members to the other. The longitudinal reciprc- 10 cating motion imparted to the bar members of the non-rigid set by rotation of the actuating member or members about inclined axes causes the thread or the like wound on the reel to advance lengthwise of the reel in a plurality of 15 spaced, generally helical turns.

One form of reel embodying the invention is illustrated in Figure 1, which shows a longitudinal sectional elevation of the reel, the section being along line I--I of Figure 2. Figure 2 is go an end elevation of the reel from line 2-2 of Figure 1. Figure 3 isa plan of the reel from line 3-3 of Figure 2, parts being broken away more clearly to show the construction of the reel. Figure 4 is a detail on an enlarged scale of one form of means which may be employed for mounting the bar members of the non-rigid set. Figure 5 is a sectional elevation from line 5-5 of Figure 4. Figure 6 is a sectional elevation, from line 66 of Figure 7, showing modified means for mounting the actuating members on the supporting frame of the reel. Figure '7 is a sectional elevation of the modification of Figure G'from line 1-1 of Figure 6. Figure 8 is a sectional elevation from line 8-8 of Figure 7. 85

In the drawings, like reference numerals refer to like parts throughout.

The reel shown in the drawings comprises a rigid, generally cylindrical reel member I and a non-rigid, generally cylindrical reel member 2. 40 Rigid reel member I has a periphery formed of a plurality ofspaced, longitudinally extending bar members 3 with which alternate the bar members 4 forming the periphery of non-rigid reel member 2. While reel member I may take 46 any of various forms and may be mounted and drivenin various ways, in the embodiment shown it comprises arigid, cage-like member 5 which embodies the. bar members 3, supported at one end thereof by spider 6 and provided at the 60 other end with an external annular ring I. The latter may serve'to reinforce the bar, members 3 and may constitute a guide for the thread or the like. The cage-like member 5 is supported at the operating end of the reelby an angular supporting member 3 fixed to the annular ring I, as

by cap-screws 9. Annular supporting member 3 i journalled on the frame member II on which the reel is mounted. The illustrated reel is driven by a shaft I2 journalled in frame member II concentrically with annular supporting member 8. Spider 5 of reel member I is mounted on and fixed for rotation with the shaft l2 by key I3 and cap-bolt I4 threaded into the end of shaft '2.

The non-rigid reel member 2 comprises a set of bar members 4 non-rigidly mounted on two actuating members I5 and I6, preferably of disklike form, rotatably supported about axes offset from and slightly inclined to the axis of the shaft I2 and consequently to the axis of rigid real member I. The axes of actuating members l5 and It are preferably disposed as illustrated in parallel relation to each other. In the embodiment shown, actuating members I5 and iii are rotatably mounted on frame member II, suitable means being provided to locate them in the desired position. In the means illustrated, ringnut I1, threaded onto frame member II and locked into position by set-screw I 3, and bearing washer iii are provided to retain actuating member I5 against a suitable shoulder 20 on frame member I I. If desired, suitable means such as oil grooves 2| may be provided to'lubricate shaft I2 and the bearing surfaces on which actuating members I5 and it are journalled.

Bar members 4 of non-rigid member 2 are nonrigidly mounted on actuating members I5 and It by means providing movement in a variety of different directions such, for example, as the means illustrated in Figures 4 and 5. In the mounting means illustrated, the corresponding bar member 4 is provided with a slot 22 into which projects the end of pin 23 pivotally mounted therein by a pivot pin 24. If desired, the end of pin 23 may be flattened as shown to provide guiding surfaces to bear against the walls of slot 22 in the bar member 4. The pin 23 is journalled in a suitable sleeve nut 25 threaded into the corresponding actuating member, in Figures 4 and 5 bearing reference numeral I5. By means of sleeve nut 25 and head 25 on pin 23, pin 23 is maintained in the desired position with relation to actuating member l5, being prevented from movement other than rotary movement about the axis of pin 23, while the bar member 4 is allowed a pivotal movement about pivot pin 24.

By the mounting means above described, each bar member 4 is permitted substantially universal motion with respect to actuating members I5 and IS without, however, being permitted to twist about an axis extending longitudinally of the bar members. Furthermore, the mounting means illustrated provides ease of assembly of the nonrigid member, since pin 23 may first be passed through sleeve nut 25 after which the corresponding bar member 4 may be fastened to pin 23 by pivot pin 24, the bar members 4 being then fastened in the desired position on actuating members I5 and I6 by simply screwing the sleeve nuts 25 into threaded holes provided on the periphery of the actuating members.

The reel illustrated is particularly adapted for employment in the continuous processing of thread or the like, particularly in the wet processing of thread or the like, wherein processing liquid is applied to the thread or the like by showering the liquid on the thread or the like from distributors disposed thereabove. Since suchprocessing liquids, as well as other processing media which may be used. may be corrossive in character, it is desirable that the reel be constructed of materials and/or in a manner resistant to chemical action. This end is accomplished in the illustrated reel, in which parts such as cage-like member 5, annular supporting member 8, cap-screws 9, bar members 4, and rotatable actuating members I5 and I5 may be formed of suitable material, such as synthetic resin, resistant to the action of processing media; while flexible sealing means, such as the bellows-

like members

29, 30 and 3| may be provided as indicated to enclose the interior portions of the reel, including the bearing surfaces, etc.

The bellows-like members may be mounted in any suitable manner, such as that shown. Member 29 is conveniently mounted on the hubs of spider 6 and actuating member I5. Member 30 is similarly mounted on the hubs of actuating members I5 and I6. Member 3i has one end thereof mounted on the hub of actuating member l6 and the other end clamped between cage member 5 and annular supporting member 3. The sealing means, besides protecting parts which might be damaged by processing medium, also prevent the escape from the interior of the reel of lubricants which might otherwise soil thread or the like wound on the reel. Furthermore, in the illustrated embodiment, the bellows-like sealing member 30 extending between actuating members I5 and I6 may also serve to urge actuating member I6 against the locating shoulder formed on frame member II, thus aiding bar members 4 in maintaining actuating member It in the correct position on frame member I I. The mounting means by which the bars 4 are connected to the actuating members I5 and I6 may obviously be made of metallic or non-metallic materials resistant to the action of the particular processing media employed.

In operation of the reel, rigid reel member I is rotated by shaft I2. Contact of the bar members 3 of rigid reel member I with the bar members 4 of non-rigid reel member L causes the latter reel member to rotate therewith. As shown in Figure 2, lateral displacement with respect to the axis of rigid reel member I of the axes on which actuating members I5 and I6 are mounted causes bar members 4 of non-rigid reel member 2 to project outward beyond bar members 3 of rigid reel member I during part of the complete revolution of the reel. Bar members 3 of rigid reel member I likewise project outward beyond those of non-rigid reel member 2 during the other part of the revolution. Thread or the like wound on the reel is thus transferred during the rotation of the reel from the bar members of one reel member to the bar members of the other reel member.

The mounting of the actuating members I5 and I6 about inclined axes causes bar members 4 mounted on actuating members I5 and It to be reciprocated lengthwise of the reel, the direction of offset and direction of inclination of these axes being so related that when said bar members 4 of non-rigid reel member I are projected beyond the bar members 3 of reel member I they are moved lengthwise of the reel in one direction, while when they are withdrawn within the generally cylindrical Deriphery defined by the bar members 3 of reel member I, they are moved lengthwise of the reel in the opposite direction. The lengthwise movement of the bar members 4 of non-rigid reel member 2 produces bodily advance of the thread or the like during that portion of the revolution of the reel during which these bar members support the thread or the like.

The thread advancing action of the reel of the present invention i generally similar to that of the reel shown in United States Patent No. 1,983,221 to William H. Furness. It will be understood that the thread or the like will move, for a given direction of rotation of the reel and for a given direction of lateral displacement of the axes of actuating members l5 and It, in a direction along the reel determined by thedirection of inclination of the axes of said actuating members 15 and I6 with respect to the axis of rigid reel member I. Further, as the amount of inclination of these axes is modified, it is obvious that the pitch or lead of the generally helical turns of .thread or the like is proportionately modified.

In the illustrated embodiment of the invention, for the direction of rotation indicated by the arrow in Figure 2 the thread or the like will advance along the reel from right to left as seen in Figures 1 and 3. This direction of advance; i. e., from the supported end of the reel to the unsupported end, constitutes the preferred direction of advance in cantilever reels; but it is, of course, obvious that by suitable modification of the construction of the reel the thread or the like could be caused to advance in the opposite direction.

The net effect of the operation of the reel is to cause the thread or the like to be wound turn afterturn about the reel in substantially helical form, the succession of turns meanwhile advancing bodily lengthwise of the reel. In this manner thread or the like led to the reel may be stored thereon in the form of a large number of closely spaced turns, as many as several hundred, de pending upon the length of the reel.

The reel illustrated, besides having the advantages of cantilever construction has also the ad-,

vantage of being readily assembled and disassembled. For instance, by removal of cap-bolt l4 and cap-screws 9, rigid reel member I may be disassembled and cage-member 5 removed, after which, by removal of the ring-nut H, the nonrigid member 2 and annular supporting member 8 may be readily slid off the frame member II. In the assembly of the reel, the parts of nonrigid member 2 can be assembled separately and the remainder of the reel assembled in the order opposite to that above indicated.

As shown in Figures 6 to 8, inclusive, actuating members [5 and I6, indicated by broken lines, may be mounted on a sleeve member 32 mounted on the frame member Ila of the reel, being held in the desired position thereon by set-screw 33. The frame member Ha, as shown in Figure 7, may be provided with a cylindrical exterior on which is mounted sleeve member 32, the axis of which is offset from but parallel to the axis of the bore for the drive shaft l2. The sleeve member 32 may therefore be formed with external surfaces which are substantially concentric, except for the inclined cylindrical bearing surfaces 34, 35 on'which are rotatably mounted actuating members [5 and Hi. It may be desirableto mount actuating members [5 and [6 on sleeve member 32 as shown in this embodiment, since the inclined bearing surfaces 34, 35 for actuating members l5 and It may be readily machined on said sleeve member 32, which may be more easily held in the machining apparatus than the frame member ll. Furthermore, it is obvious that by rotating the sleeve member 32 on the external cylindrical surface of the frame member Ha,

the offset and inclined relationship of the various axes is varied and thus the amount of'pitch or lead of thehelical turns of thread on the reel correspondingly varied.

It is apparent that under suitable circumstances only one actuating. member need be provided to reciprocate the bar members of a non-rigid member, the bar members being supported by suitable means. Furthermore, it may be possible to have both sets of bar members of the reel of a non-rigid construction in which the bar members of each set are reciprocated lengthwise of the reel by one or more actuating members similar to actuating members l5 and ,16 the ofiset and inclinedrelation of the axes of rotating parts of the respective reel members being arranged to provide a lengthwise movement of the bar members of each set inthe desired direction when said bar members are supporting the thread or the like wound on the reel. It is to be understood that the above described reel is but an illustrative embodiment of the invention and that various other embodiments may be devised and various modifications besides those above indicated may be made in the illussuitable expression in the appended claims, whatever features of patentable novelty reside in the invention.
