16 Claims.

This invention concerns a novel form of windingreel.

More particularly, the invention relates to a winding reel comprising a plurality of interdigitating sets of longitudinally extending bar members, the sets being usually, but not necessarily, two in number. In winding reels of the kind to which the invention relates, the bar members of the respective sets are so disposed that, m-during rotation of the red as a whole, at least some of the bar members of each set are caused to project beyond the periphery defined by the bar members of the other set. Material such as thread or the like, hereinafter referred to as "thread, wound about the reel is thus transferred in the course of the revolutionof the reel from the bar members of one set to the bar members of the other set. The bar members of at least one set are adapted to move axially during rotation of the reel, whereby the thread is caused during rotation of the reel to advance lengthwise thereof in a plurality of spaced generally helicaltums.

Among other things, the presentinvention 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 relatively long lengths of thread in a small space in a plurality of spaced generally helical turns and may, therefore, be conveniently employed in the continuous processing of thread. Cantilever thread storage reels, such as that provided by the present invention, may be employed to particular advantage inasmuch as they lend themselves to disposition in arrangements in which, by virtue of their open-ended construction, threading up and other manipulation of the thread stored on the reels, inspection, replacement, repair, etc., are very greatly facilitated.

Two diflerent cantilever reels are illustrated as 45- embodying the invention.

One of the cantilever reels herein illustrated comprises a rigid, generally cylindrical set of longitudinally extending bar members having alternating therewith the bar members of a non- 50. rigid, generally cylindrical set of longitudinally are so arranged that, during rotation of the reel,

66 some of the bar members thereof project laterally beyond the periphery of the other set of bar members and, while so projecting, are moved lengthwise of the reel. This is accomplished in this embodiment of the invention by slidably mounting the bar members of the non-rigid set 5 on suitable supporting means rotating about an axis oilset from the axis of the rigid set, the movement of the bar members of the non-rigid set being governed by suitable cam means. The

other cantilever reel illustrated is generally sim- 10 ilar, but comprises two non-rigid, interdigitating sets of longitudinally extending slidably mounted bar members supported from the same end of the reel.

In both embodiments of the invention, rotation 15 of the reel causes thread to wind onto the reel. The projection of the bar members of one set beyond the periphery of the other set causes thethread to be transferred from one set of bar members to the other. The axial movement imparted to such slidably mounted bar members as project at any given time beyond the periphery of the other set causes the turns of thread wound on the reel to progress lengthwise thereof. The effect of this action is to cause thread to advance lengthwise of the reel in a plurality of spaced, generally helical turns.

In the drawings, Figure 1 is a longitudinal section-along line i-l of Figure 2 of a cantilever; reel comprising a rigid set of bar members and a non-rigid set of bar members. Figure 2 is an end elevation of the reel of Figure 1 from line 22 thereof. Figure 3 is a plan of the reel from line 3-3 of Flgure-2, parts being broken away more clearly to show the construction of the reel.

Figure 5 is asectional elevation along line 5--5 of Figure 6 of another form of cantilever reel embodying the invention, the same comprising two non-rigid sets of bar members. 4 Figure 6 is an elevation substantially along line 6-6 of Figure 5 of the reel. Figure '7 is a sectional elevation along line 1-1 of Figure 5. Figure 8 is a plan elevation of the reel from line 8-8 of Figure 6, parts being broken away more clearly to show the construction of the reel. Figure 9 is an incomplete sectional elevation from line 9-9 of Figure 6, parts being intentionally omitted in order more clearly toshow the construction and g the principle of operation of the reel. Figure 10 is a detail elevation of a cam which may be employed to actuate the bar members of the reel.

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

The reel shown in Figures 1 to 4, inclusive, comprises a rigid, generally cylindrical reel member I and a non-rigid, generally cylindrical reel member 2. Rigid reel member I has a periphery comprising a plurality of spaced, longitudinally extending bar members 3, with which alternate the bar members 4 forming the periphery of nonrigid reel member 2. While reel member I may take various forms and may be mounted and driven in various ways, in the embodiment shown it comprises a rigid cage-like member 5 which embodies the bar members 3 supported at one end thereof by a spider 6 and provided at the other end thereof with an external annular ring I. The latter serves to reinforce the bar members 3 and may constitute a guide for thread wound on the reel, as is preferable in the case of cantilever reels, from the supported end of the reel. The cage-like member 5 is supported at the operating end of the reel by an annular supporting member 8 fixed to the annular ring I as by cap screws 9. Annular supporting member 8 is journalled on the frame member I I on which the reel is mounted. As illustrated, the reel is driven by a shaft I2 journalled in frame member H concentrically with annular supporting member 8. Spider 6 of reel member I is mounted on and fixed for rotation with the shaft I2 by key I 3 and cap bolt I 3 threaded into the end of shaft I2.

Various means may be provided for causing the bar members 5 of non-rigid member 2 to pro.- ject laterally beyond the periphery of the rigid member I during rotation of the reel and moving such bar members, while so projecting, length- Wise of the reel. In the embodiment of the invention shown, the projection of the bar members t beyond the periphery of rigid reel member I is accomplished by mounting the bar members 4 on a supporting member I5 which is rotatably mounted on frame member II about an axis offset from the axis of rigid reel member I. Bar members 4- are slidably mounted on slots It formed in the periphery of supporting member I5 and, by suitable means, are moved lengthwise of the reel in one direction when they are projected beyond the periphery of rigid reel member I and in the opposite direction when by rotation of the reel they are retracted to a position within the periphery of rigid reel member I. Such means in the embodiment illustrated comprises a cam head I I having in its generally cylindrical periphery a suitable cam groove I8, cam bead I'I being rigidly mounted on frame member I I, as by set screw I9 and key 2|, with the axis of cam head I! coincident with the axis of rotation of supporting member I5.

Pins 23, of which one is fixed to each bar member 4, are disposed in cam groove I8, which is preferably of the form illustrated in Figures 1 and 3 and so related to the direction of oifset of the axes of rigid reel member I and supporting member I5 that, as the pins 23 slide in groove I8 during rotation of the reel, the bars 4 are moved lengthwise of the reel in one direction, as from right to left in these figures, when the bar members I project beyond the periphery of the reel member I, and in the other direction, as from left to right in these figures, when the bar members 4 are disposed within the periphery of the reel member I. While slots I6 in supporting member I5, in which slots are disposed the bar members 4, may be of various shapes, the T-slots illustrated are preferable since, as is desirable, they confine the bar members 4 against any movement with respect to supporting member I5 eX-= cept the desired sliding movement longitudinally thereof.

In operation of the reel illustrated in Figures 1 to 4, inclusive, rigid reel member I is rotated by shaft l2. Contact of the bar members 3 of rigid reel member I with the bar members 4 of nonrigid member 2 causes the latter reel member to rotate therewith. As shown in Figures 1, 2 and 4,

the lateral displacement with respect to the axis of rigid reel member I of the axis about which supporting member I5, and consequently bar members I, rotates causes bar members I to project outward beyond bar members 3 of rigid reel member I during part of the complete revolution of the reel and to be withdrawn within the periphery of rigid reel member I during the other part of the revolution. Thread wound on the reel is thus transferred during rotation of the ree from the bar members of one reel member to the bar members of the other reel member.

During rotation of the reel in the direction indicated by the arrow in Figure 2, the pins 23 of bar members 4 slide in cam groove I8 and thus cause the bar members l to move lengthwise of the reel; i. e., from right to left in Figures 1 and 3, while the bar members d are laterally projected beyond the periphery of rigid reel member I and from left to right, or back to their original position, when bar members l are disposed within the periphery of rigid reel member I. Such lengthwise movement of the bar members 4 of non-rigid member 2 produces-bodily advance of the turns of thread wound on the reel during that portion of the revolution of the reel during which the bar members 3 support the thread. It will be understood that the thread will move for a given direction of the rotation of the reel in a direction along the reel determined by the direction of inclination of the cam groove I8. Further, as the amount of inclination of cam groove I8 is modified, it is obvious that the pitch or lead of the generally helical turns of thread is proportionately modified.

In the embodiment of the invention illustrated in Figures 1 to 4, inclusive, for the direction of rotation indicated by the arrow in Figure 2 the thread will advance along the reel from right to left. 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 construction of the reel the thread could be caused to advance in the opposite direction. The net effect of the operation of the reel is to cause the thread to be wound turn after turn about the reel in substantially helical form, the succession of turns meanwhile bodily advancing lengthwise of the reel. In this manner thread led to the reel may be stored thereon in the form of a large number of closely spaced turns, as many as several hundred, depending upon the length of the reel.

The cantilever reel illustrated in Figures 5 to 10, inclusive, comprises two non-rigid sets of

bar members

25 and 26. While the bar members of said non-rigid sets may be mounted and actuated in variousmanners, in the embodiment shown the

bar members

25 and 26 of both sets are slidably mounted in suitable slots 21 in the periphery of a supporting member 28 which is rotatably mounted about arigid frame member 29. Supporting member 28 is adapted to be rotated by driving member 3| mounted on a sleeve 32, journalled on frame member 29 and rotated by suitabl means as

gears

33 and 34. Pins 35, fixed to (iii supporting member 28 and extending between the

bars

25 and 26 into suitable openings 36 in the driving member 3|, provide driving connection between supporting member 28 and driving member 3|. During rotation of supporting member 28, the

bar members

25 and 26 are given the desired movement by means of suitable cam heads 31 and 38 rigidly mounted on frame member 28.

In the reel shown, thecam head 31 at the open or forward end of the reel is mounted on frame member 28 by means of key 39 and nut 41, while the cam head 38 at the,,inner or rearward end of the reel is mounted on frame member 29 by means of key 42 and ring nut 43. Each of the cam heads 31 and 38 is provided with two

cam grooves

44 and 45 and with two end cam surfaces 46 and 41, as shown to advantage in Figures 9 and 10. Each of the bar members 25 is provided with finger portions 48 carrying pins 49 which are adapted to operate in grooves 44 of the cam heads, while each of the bar members 26 is provided with somewhat longer finger portions 5| carrying pins 52 which are adapted to operate in grooves 45 of the cam heads.

To provide additional support to the

bar members

25 and 26 and

finger portions

48 and 51 thereof, supporting member 28 may be formed as shown in Figures 5, 6 and 1. Supporting member 28 may be provided with extending portions 53 at the ends, in which case the

bar members

25 and 26 are supported for a greater distance along their length than otherwise possible and the relatively short fingers 48 of bar members 25 are supported against twisting movement.- In addition, if desired, suitable lugs 54 may be provided, as indicated, at the ends of supporting member 28 to support the ends of the fingers 51 of the bar members 26 against twisting movement.

The

cam grooves

44 and 45 in each

cam head

31 or 38 are, as shown in Figure 10, of such form and so related to each other that as supporting member 28 rotates, the

pins

49 and 52 of'

bar members

25 and 26, operating in the

cam grooves

44 and 45, cause the bar members 25 of one set to be projected beyond the bar members 26 of the other set during part of a revolution, while during another part of the revolution the bar members 26 are projected beyond the bar members 25. The end cam surfaces 46 and 41 are preferably so formed and so related to the corresponding

cam grooves

44 and 45 that, during rotation of the supporting member 28, at least some of such bar members 25 as are at any time projecting beyond the bar members 26 are moved lengthwise of the reel by contact of the fingers 43 of bar members 25 with end cam surfaces 46, and at least some of such bar members 26 as are at any time projecting beyond the bar members 25 are moved in the same direction lengthwise of the reel by contact of fingers 5i of bar members 26 with end cam surfaces 41, the bar members of each set being moved back to their original positions when they are withdrawn other figures, the upper portion of cam groove 44 between the points A and B, and the lower portion of cam groove 45 between points and D. are arcs of circles concentric with the axis of rotation of supporting member 28, while the remaining portions of the

cam grooves

44 and 46 are of such form that in each case the distances therefrom to the aforementioned center of rota- 'tion are less than the radius of curvature of the circular-arc portion of the corresponding cam .groove.

Therefore, as supporting member 28 rotates carrying

bar members

25 and 26 with it, those of the bar members 25 which have their pins 43 in the upper portion of cam groove 44 are projected beyond the bar members 26 which have their pins 52 in the upper portion of cam groove 45, and thus'carry the threads; iwliile those of the bar members 26 which have their ipin's 52 in the lower portions of groove 45 are p 'iected' beyond the bar members 25 which have ,t pins in the lower portion of cam groo' 8 and thus carry the thread. The thread wound on the reel is thus carried by some of thebar members of both sets, the transfer of the thread fromthe bar members of one set to the bar members of the other set taking place when the pins of the bar members pass the transfer points A, C, and B, D, on the cam heads. By suitable forms of

grooves

44 and 45 it is thus possible to provide a reel having a substantially cylindrical periphery, which reel may be comprised of two generally cylindrical, non-rigid, interdigitating sets of bar members. v The end cam surfaces 46 and 41 are preferably of such form and so arranged that when bar members and 26 pass the transfer points t, C, and B, D, of

cam grooves

44 and 45, the

bar members

25 and 26 are in their extreme positions lengthwise of the reel as shown in Figure 9. In the cam head of Figure 10, which, as has been mentioned, represents cam head 38, the low point E of cam surface 46 is opposite the point A of cam groove 44 and the point F of cam surface 46 is opposite point B of cam groove 44. The bar members 25, the pins 49 of which are disposed incam groove 44, are thus in their extreme rearward position as they pass point E, the cam surface 46 being preferably uniformly inclined between the points E and F, as indicated in Figure 9. The high point G of cam surface 41 is opposite the point C of cam groove 45 and consequently opposite the low point E of cam surface 46; while low point H of cam surface 41 is on posite point D of cam groove 45 and high point F of cam surface 46. Consequently, when bar members 25 are in their extreme rearward position bar members 26 are in their extreme forward position and vice versa, these extreme positions being opposite the transfer points A, C, and B, D, of

cam grooves

44 and 45. Obviously, cam head 31 corresponds to cam head 38.

In operation of the reel illustrated in Figures 5 to 10, inclusive, driving member 3| is rotated by

gears

33 and 34 and supporting member 28 is driven from driving member 3l by pins 35. During such rotation of member 28, the

bar members

25 and 26 of the two sets are so actuated by

cam grooves

44 and 45 that during part of a revolution of the reel the bar members 25 are projected beyond adjacent bar members 26, while during another part of a revolution of the reel the bar members 26 are projected beyond adjacent bar members 25. Thread woundon the reel is thus transferred during rotation of the reel from one set of bar members to the other set of bar members. Likewise, during such rtation, such of the bar members 25 as are projected beyond adjacent bar members it and such of bar members 26 as are projected beyond adjacent bar members 25 are moved lengthwise of the reel in the same direction by contact of the fingers $8 and of the

bar members

25 and 26 with the corresponding end cam surfaces 46 and 41 of the cam heads 31 and 38, thus producing bodily advance of the thread during rotation of the reel, the bar members of each set being moved back to their original positions when they are retracted within the periphery of the other set.

Ill

It will be understood that the thread will move, for a given set of cam heads having a particular relation of cam grooves M and t5 and cam surfaces 46 and ll, in the direction determined by the direction of rotation of the reel. For the direction of the rotation indicated by the arrow in Figure 6, the thread will advance along the reel from right to left or from the supported end of the reel to the unsupported end which, as has been indicated, is the preferred direction of advance in cantilever reels. To guide the thread as it starts on the reel at the supported end, the actuating member 3! may be formed as shown to provide a thread guiding ring-like portion 58. The net effect of the operation of this reel, as of the reel previously described, is to cause the thread to be wound turn after turn about the reel in substantially helical form, the succession of turns meanwhile advancing bodily of the reel.

The reels illustrated may be employed in the continuous processing of thread, particularly in the wet processing of thread, wherein processing liquid is applied to the thread by showering such liquid on the thread. Since such processing liquids, as well as other processing media which may be used, may be corrosive in character, it is desirable that the reels be constructed of material and/or in manners resistant to chemical action. This end is accomplished in the illustrated reels by making as many parts as may conveniently be so made of non-metallic material, such as synthetic resin, which is resistant to the action of processing media. Such parts in the illustrated reels are indicated by heavy sectioning, while other parts which, for various reasons, may not be so conveniently formed of such materials may be made of metallic materials resistant to such chemical action. In this manner,

the number of parts which are formed of chemical resistant metals are reduced, wherefore the cost of the .reel is reduced. As is apparent from the drawings, various parts of the reel which can be made of non-metallic materials such as synthetic resins may be molded of such materials.

Each of the illustrated reels may be readily disassembled and reassembled. For instance, in the reel shown in Figures 1 to 4, inclusive, by removal of cap bolt I4 and bolts 9, the cage-like member 5 may be removed from the assembly of the reel. By loosening set screw l9 or cam head I l, the cam head I! and the assembly comprising supporting member l5 and bar members 4 may be slid off frame member ll together with annular supporting member 8, and disassembled separately. In. the assembly of this reel, the reverse procedure obviously is followed. In the reel illustrated in Figures 5 to 10, inclusive, by the removal of bolt 4|, cam head 31 may be removed from frame member 29, thus making it possible to slide supporting member 28 and the

bar members

25 and 26 disposed in the slots thereof, oil. frame member 29, the driving pins 7 35 readily sliding out of the holes 36 in driving member 3|. Cam head 3! may be removed by unscrewing ring nut 43, making it possible to remove driving member Sl. This reel may be assembled in the reverse order to that required for disassembly.

It is to be understood that the above described reels represent but illustrative embodiments of the invention. Various other embodiments may be devised, various modifications may be made in the embodiments above described, and reels 0f the type provided by the present invention may be employed in uses other than the one indicated without in any way departing from the spirit of the invention. Whereas, in the specification, the reels of the present invention have been discussed in connection with the winding of thread, it is obvious that reels of the type provided by the present invention may be employed in the winding of materials other than thread. It is therefore intended that the term thread in the appended claims shall be understood to comprehend all materials which are capable of being wound on such reels.

It is intended that the patent shall cover, by suitable expression in the appended claims, whatever features of patentable novelty reside in the invention.
