Definitions
- This invention relates to winding reels of the type which, during rotation thereon-continuously wind strip material thereon, advance it lengthwise thereof in a plurality of generally helical 6 turns, and unwind it therefrom.
- the winding reels of the present invention findcommercial application in a variety of 'ways.' They may, for example, be employed to advantage for continuously but temporarily storing in a small, compact space any suitable strip material, such as thread, ribbons, films, artificial horsehair, artificial straw, bundles of filaments, etc., all of which are for convenience referred to hereinafter as thread.
- the reels illustrated as embodying the invention which are of relatively large diameter, are applicable to the manufacture of fibers of staple length by a continuous process performed on apparatus of the type shown, described and claimed in application Serial No. 144,582, filed May 25, 1937, by Hayden B. Kline and Lavern J. Jordan.
- threads consisting of thousands of filaments are formed, continuously but temporarily stored on a series of reels, and subjected to any desired processing media, after which the filaments are severed into fibers.
- Reels of relatively large size are required because of the fact that the large threads require considerable space on the 'reels and hence the pitch of the helices formed by the reels must be large in order to prevent overlapping of the adjacent threads.
- Figure 1 illustrates a plan view of a reel embodying the present invention, together with its associated supporting and driving apparatus.
- Figure 2 is a front elevation of the.
- Figure 7 is an elevation of an. individual bar member adapted to be mounted as 5 shown in Figure 6.
- Figure 8 is an end elevation from line 8-8 of Figure 9 of another form of reel embodying the invention.
- Figure 9 -ls a sectional elevation through said reel from line 99 of Figure 8, parts 10 of the reel beyond the section being omitted for the sake of clearness.
- Figure 10 is an elevation on an enlarged scale of the hub member on which are mounted the supporting members of the driving reel member.
- Figure 11 is an elevation on 15 the same scale as Figures 8 and 9 of an individual bar member forming part of the driving reel member.
- Figure 12 is a sectional elevation of said bar member on an enlarged scale from line l2-l 2 of Figure 11.
- Figure 13 is an elevation of the 20 inner supporting member for the bar members of the driving reel member.
- Figure 14 is a sectional elevation of the supporting member of Figure 13 from line i l-l4 thereof.
- Figure 15 is an elevation of the inner supporting member for the bar 25 members of the driven reel.
- the reel of the first embodiment of the 80 invention is formed of two wholly rigid reel members i and 2 each of which is substantially circular in cross section.
- Each of said members is shown as of substantially cylindrical form, although they may, if desired, beof other forms;'85 e. g., frusto-conical.
- Reel member I has a periphery formed of longitudinally extending radially projecting bar members 3, while reel member 2. has a periphery made up of longitudinally extending radially projecting bar members 4, the bar 40 members of the two reel members being alternately disposed so that the two reel members occupy substantially the same space.
- Each of the reel members is mounted for rotation about its own individual axis, the axes of the two reel 45 members being inclined from parallelism with each other in a manner which causes thread wound about the reel members to advance lengthwise thereof during rotation of said reel members.
- the reel members are mounted for rotation about axes which are disposed in inclined relation to each other in parallel planes.
- driving reel member I is concentrically 56 mounted on and for rotation with a drive shaft I journalled in a frame member 8 which, as shown in Figure 1, is provided with a flange I by means of which it is mounted as by bolts I on the frame 2 of the apparatus as a whole.
- Reel member I may therefore for convenience be called the concentric reel member.
- the driven reel member 2 is mounted on said frame member I for rotation about an axis displaced as above described from the axis of rotation of driving reel member I, wherefore driven reel member 2 may be called the eccentric reel member.
- a helical gear ll meshing with a helical gear i 2 on shaft I 3, which may be rotated by any suitable means (not shown).
- the reel drive shaft I is rotatably supported in frame member 8 by means of spaced anti-friction bearings I4 and I 5 which may conveniently take the form of ball bearings.
- the outer race of the bearing I4 is located in frame member 6 against a shoulder I 8 while the inner race of said bearing is positioned on drive shaft 5 on a finished portion l1, being located against shoulder ll.
- hearing I I is disposed between shoulders I! and I8.
- Bearing I 5 which is positioned at the supported end of frame member 0, is mounted with its inner race on finished portion I! of drive shaft I while -its outer race is located in a suitably finished bore 2
- a washer 22 is caused by means of a collar 24 located on drive shaft 5 to bear against the rear surface 23 of frame member 6.
- concentric reel membe I comprises a hub portion 26 held on portion 25 of drive shaft 5 against a shoulder 21 on said drive shaft by means of cap nut 22 threaded on the end thereof. Positive driving enga ement is provided by a pin 29 passing through said drive shaft which pin 29 engages a slot 30 at the rear of said hub member.
- and 32 which may, as shown, be of substantially circular disc-like form, are rigidly affixed to said hub member 28, as by bolts 32.
- Bar members 3 of concentric reel member I are mounted in slots II on the eripheries of said sup ortin members if and 32, as shown in Figure 2.
- Said bar members, which are formed as in Figure 4. have a longitudinally extending portion and a portion 38 extendin radially toward the interior of the reel which latter portion is provided with shoulders 31 against which said discs M and 32 bear.
- Each of the bar members I is firmly fixed to members 3! and 32 by means of taper pins 28 at at least one radial intersection of said bar members and each of members if or 32.
- Said pins serve to hold the bar members 3 firmly in said sup orting members 3
- the holes for the pins 38 are preferably drilled and reamed in the initial assembly with the bar members in place.
- the bar members 3 are rovided with such radially extending portions 3 and longitudinally extending portions 35 in order that they may extend over and surround the supporting means for the bar members of the other reel member 2 without interference with the bar members or other parts of said other reel member.
- reel mem- 'slots 24 in their peripheries. in which slots are disposed the bar members of reel member 2.
- each of said bar members I is provided with shoulders 31 against which bear supporting members 28 and 40.
- Each comprises a longitudinally extending portion II and a radially extending portion 26 which permit the bar member to extend beyond the supporting means for bar members 3 of reel member I.
- Bar members 4 are shown as held in supporting members 20 and 40 by means of pins 38 at the radial intersections of said bar members and said supporting members in a manner similar to that described in connection with reel member I.
- the supporting members 39 and ll are mounted on and spaced apart by a cylindrical sleeve ll which in effect forms the hub of reel member 2, the supporting members 3. and being recessed as shown for the purpose of locating them with respect to said sleeve.
- the inner supporting member 39 terminates at the interior bore of said sleeve for the purposes of assembly, while the outer supporting member ll extends inward and serves to aid in locating the reel member 2 and the anti-friction bearing 42 by means of which the reel member 2 is 1'0- tatably mounted on the frame member 8.
- Bolts 42 and nuts ll spaced at intervals around reel member 2 serve to clamp the supporting members 30 and ll together on the sleeve ll and against shoulders 21 on bar members 4, thus forming a rigid assembly of bar members I, members 3! and ll, and sleeve 42.
- a tubular member 45 surrounding each bolt 43 may be provided to protect the bolts 43 from processing media and to aid in spacing the members 39 and III.
- anti-friction bearing 42 comprises a roller bearing made up of an outer race 46 mounted in sleeve I and an inner race 41 mounted on a sleeve ll fixed to frame member 0, rollers 49 being disposed between said races.
- Rings 50 shown as disposed at both ends of said rollers 49, may form parts of the cage for spacing said rollers,- They may also serve to aid in sealing the bearing against the entrance of extraneous materials such as the processing medium or against the escape of lubricant from the bearing itself.
- Sleeve 48 to which is mounted the internal race 41 of the anti-friction bearing 42, and consequently reel member 2, is formed with an inner cylindrical surface by means of which it is journalled on a cooperating cylindrical surface of frame member 6.
- Said cylindrical surface on frame member 8 has. its axis parallel to but offset from the axis of drive shaft 5.
- the external 7 surface of sleeve 48 is likewise cylindrical, but its axis is inclined from parallelism with the axis of its internal bore, so that when the sleeve 48 is mounted in the intended position on frame member I, the axis of its external cylindrical surface is disposed in inclined relation to the axis of drive shaft 5 but in a plane parallel to and offset therefrom. 1
- Said sleeve I. is rigidly fixed in the desired pomtion on frame member I by means of screw II.
- Disc-like member 52 is bolted to said sleeve 42 to hold the reel member 2 in position with respect to frame member 8' and also to protect the interior mechanism of the reel member.
- Reel member 2 is thus located endwisev on frame member 6 between shoulder 53 on sleeve II and member 52.
- a disc 84 may be mounted at the end of the reel member 2 and a sleeve of reagent-resistant material 55 may be mounted on the rear portion of sleeve 48 to protect the rear of the reel from possible attack by the processing liquid.
- the slots in the supporting members in which the bar members are disposed may be of such shape that the bar members fitting therein are prevented from radial movement. This may be accomplished by making the slot of enlarged cross section .below the surface of the supporting member and forming the bar members so that they closely fit therein, whereby radial movement of the bar members with respect to the supporting members is eliminated.
- a dovetail arrangement is provided; that is, the slots 34' in each supporting member taper outward toward the bottom of the slot and the bar members 3' are provided with corresponding portions 56 which feed into said slots. Consequently, when each reel member is assembled, the supporting members are held against the shoulders 31 on the bar members'while radial movement of the bar members with respect to the supporting members is prevented by the dovetail joint.
- Each of the reels shownas embodying the invention is of cantilever form; that is; it is supported from one end only and has the other end thereof unsupported so that thread can be wound on or unwound over the end of the reel.
- the operation of the reel is similar to that of the reel shown, described, and'claimed. in copending application Serial No. 652,089 for Winding reel, filed January 16, 1933, by Walter -F. Knebusch.
- the offset relation of the reel members causes the thread wound about the reel to be carried for half the circumference of the reel by the bar members of each set; that is, for one-half a revolution of the reel, the bar members of one reel member carry the thread, while for the other half of the revolution of the reel the bar members of the other reel member carry the thread.
- the inclined relation of the bar members causes the thread to advance lengthwise of the reel, this because of the fact that the thread winding on each reel member from the other reel member travels at right angles to the axis of rotation of the reel member to which it passes.
- the reel member la is mounted on drive shaft 5a which is journalled in frame member 6a.
- the reel member 2a is rotatably mounted on frame member 6a, the axes of rotation of said two .reel'members being offset from and inclined to each other, as is the case in the previously described embodiment.
- Drive shaft la is journaled in frame member 6a in antifriction bearings; e. g., the ball bearings a and Ila.
- the outer race of ball bearing Ma is mounted in frame member la against shoulder lid.
- the inner race of said bearing I la is located on drive shaft 5a, against shoulder I80.
- a collar 24a is mounted on drive shaft 6a to bear against the inner race of the other bearing I5a while the outer race bears against shoulder 51 in member 6a.
- the drive shaft in which is thus accurately located lengthwise of reel member to, may be driven by any suitable means such as a gear Ila.
- Reel member la is mounted on the projecting portion 25a of drive shaft So. It comprises a hub member 26a mounted on projecting portion 25a which is held thereon against a shoulder 21a on driveshaft 50 by means of a cap nut 28a threaded on the end of said drive shaft. Positive driving engagement is provided between said hub member 26a and drive shaft 5a by a pin 29a passing through said drive shaft having its projecting portions disposed in a slot 30a in hub member 26a.
- the bar members 3a of reel member la are supported by spaced supporting members 3 la and 32a which are mounted on said hub member 26a.
- Said hub member which is shown to advantage in Figure 10, isprovided on its external surface with a plurality of recesses 58 engaged by corresponding lugs 59 on said supporting members 3la and 32a which are shown advantageously in Figure 13.
- positive driving engagement is provided as between said hub member 26a and supporting members 3la and 32a.
- a. and 32a are clamped; together by bolts 60 which are threaded at one end into inner supporting member 32a and pass through outer supporting member 3 la, being provided at their ends with cap nutslil.
- Tubes 62 of suitable material such as synthetic resin are provided around bolts 60 to protect them from processing reagents.
- Washers 63 which may be made of rubber or like material, are disposed between the ends of said tubes 62 and the members 3
- cap nuts Bl which enclose the ends of bolts Gll'may be made of or coated with suitable reagent-resistant material.
- Tubes 62 may, if desired, also assist in spacing the members 3H1. and 32a apart. It has been found deslrable to dispose bolts 00 substantially as shown; that is, with a ring of said bolts near the hub 26a and another ring of bolts spaced therefrom near the bar members 3a.
- the bar members 3a are disposed in slots34a in the peripheries ofmembers 3m and 320., being rigidly held therein by means of pins 3811 at the radial section of said slots and and 12, the bar members thereof provided with enlarged portions 04 at the points where they contact with supporting members tie and 320.
- bar members 3a are provided with raised portions, such as the button -like portions 65, at the points where they come into contact with the bar members 40 of the other reel member.
- bar members la are provided with raised portions '5. Such raised portions are for the purpose of avoiding wear on other portions of the bar members due to sliding contact during operation of the pins 380 being provided to hold said bar members flrmly to said supporting members.
- a series of spaced bolts 80 disposed about reel member 2a serves to clamp supporting members "a and lla together, said bolts being threaded into inner member "a, passing through outer member a, and being adapted to be tightened by means of cap nuts I.
- Tubes 62 and washers I are provided to protect the bolts and to aid in spacing the members "a and Na, if desired.
- Reel members "a and Ila seat on hub sleeve a with suflicient pressure to hold them firmly on said sleeve.
- Supporting members "(land a and sleeve lln. may be recessed as shown to aid in locating these portions in respect to each other.
- Sleeve 4 la is mounted for rotation about frame member So by means of anti-friction bearings a and 81; e. g.. the ball bearings shown. These bearings are mounted on the external surface of frame member to in such a manner that the axis of rotation of sleeve member lid and consequently of reel member 2a is in the desired fixed oii'set and inclined relationship with respect to drive shaft la.
- Rear anti-friction bearing 61 is located endwise with respect to frame member a by means of ashoulder it, while the other anti-friction bearing 68 is located endwise by means of a spacer sleeve es disposed between bearings 88 and 61.
- the rear portion of supporting member a may be formed with a sleeve portion I2 having one or more external flns 13 .thereon to assist in preventing liquid from reaching the interior of the reel from the rear thereof.
- this embodiment of the invention includes means for preventing any p liquid which may be applied to the reel from reaching the interior mechanism thereof.
- Such means comprise a plurality of overlapping annular flanges disposed on the adjacent inner faces of the inner supporting members 32 and "a of ,reel members In and 20.
- Member 320 is provided with an annular flange portion 14 which reel member 2a.
- .Reel member 394 is provided projects toward the supporting member "a for with a similar flange portion I5 which is directed toward supporting member 32a.
- Annular flange portion 11' is of smaller diameter than 5 annuiarflange member I5; together, said annular flange P rtions effectively obstruct the space between the reel members Ia and 2a against the entrance of liquid;
- Each flange portion may be substantially 1c trough-shaped, as shown, to aid in preventing the passage of liquids. If liquid is applied to the thread on the reel, a large portion of any liquid which passes between reel members in and 2a is caught by the trough in annular flange portion 15 .15 and is discharged between the bar members on the lower portion of the reel. Any liquid which is not caught by said annular portion 15 is caught by the trough in annular flange portion 14 and is discharged from the lower portion of 2c the reel. Since these portions overlap, they effectively prevent the entrance of any liquid to the interior of the reel. Said annular flange portion thus comprises a labyrinth seal. While only two such flange portions are shown, one for each reel member, it is obvious that a large number may be provided.
- the disclike supporting member Ila is curved or dished, asshownin FigureQ,beingdisposedwithitsconvex side toward the unsupported end of the reel.
- This is advantageous because it increases the strength of the member Ma and because it makes it possible to dispose the cap nuts 28a and I in recesses 16 formed in the face of the member Sla, as shown in Figures 8 and 9. Therefore, no projections are provided at the unsupported end of the reel around which thread being discharged from the reel, can entangle as, for example, in a the threading-up operation.
- the reels above described are designed for operation over-long periods during which they are subjected to liquids. For this reason, the bearings are enclosed for protection against the entrance of processing liquids and sealing means are provided between the reel members to prevent the .e of liquid therebetween. Moreover, parts of the reels exposed to the processing liquids may be made or covered with suitable reagent-resistant materials. Thus, the parts indicated in heavy sectioning. such as the bar members, the supporting members for said bar members, the hub members on which said supporting members are mounted, the tubes sur- 5; rounding the through bolts which hold the supporting members together, the cap nuts therefor, etc., may be molded, cast, or cut of hard rubber, Bakelite, synthetic resins, or other materials resistant to the action of the processing liquids. 6
- reels embodying the present invention may be of very strong built-up constructions. This is particularly advantageous in the case of large reels, since it results in reductions in both cost and weight. Moreover, the reels of the present invention can be readily mbled by removing the nut at the end of the drive shaft, drawing the concentric reel member of! the drive shaft, and removing the member 52 or 52a. from the 71 unsupported end of the frame member 6 or a preparatory to drawing the eccentric reel member of! the frame member. Asembly of the reel may similarly be easily accomplished.

' Application December 27, 1938, Serial No. 247,813
. 15 Claims.
This invention relates to winding reels of the type which, during rotation thereon-continuously wind strip material thereon, advance it lengthwise thereof in a plurality of generally helical 6 turns, and unwind it therefrom. The winding reels of the present invention findcommercial application in a variety of 'ways.' They may, for example, be employed to advantage for continuously but temporarily storing in a small, compact space any suitable strip material, such as thread, ribbons, films, artificial horsehair, artificial straw, bundles of filaments, etc., all of which are for convenience referred to hereinafter as thread.
The reels illustrated as embodying the invention, which are of relatively large diameter, are applicable to the manufacture of fibers of staple length by a continuous process performed on apparatus of the type shown, described and claimed in application Serial No. 144,582, filed May 25, 1937, by Hayden B. Kline and Lavern J. Jordan. In said apparatus threads consisting of thousands of filaments are formed, continuously but temporarily stored on a series of reels, and subjected to any desired processing media, after which the filaments are severed into fibers. Reels of relatively large size are required because of the fact that the large threads require considerable space on the 'reels and hence the pitch of the helices formed by the reels must be large in order to prevent overlapping of the adjacent threads.
Reels of the type with which the present invention is concerned are particularly well adapted for such use since, even when of large size, they are relatively light in weight, of low cost, and operate at a minimum power consumption. It will be understood, of course, that while the invention will be disclosed hereinafter in connection with reels particularly adapted to the manufacture of fibers of staple length, reels embodying the invention may be employed for numerous other uses.
In the drawings, Figure 1 illustrates a plan view of a reel embodying the present invention, together with its associated supporting and driving apparatus. Figure 2 is a front elevation of the.
scale as the preceding figures depicting a portion of one reel member but embodying other means for holding the bar members in place on the supporting members. Figure 7 is an elevation of an. individual bar member adapted to be mounted as 5 shown in Figure 6.
Figure 8 is an end elevation from line 8-8 of Figure 9 of another form of reel embodying the invention. Figure 9 -ls a sectional elevation through said reel from line 99 of Figure 8, parts 10 of the reel beyond the section being omitted for the sake of clearness. Figure 10 is an elevation on an enlarged scale of the hub member on which are mounted the supporting members of the driving reel member. Figure 11 is an elevation on 15 the same scale as Figures 8 and 9 of an individual bar member forming part of the driving reel member. Figure 12 is a sectional elevation of said bar member on an enlarged scale from line l2-l 2 of Figure 11. Figure 13 is an elevation of the 20 inner supporting member for the bar members of the driving reel member. Figure 14 is a sectional elevation of the supporting member of Figure 13 from line i l-l4 thereof. Figure 15 is an elevation of the inner supporting member for the bar 25 members of the driven reel.
In the drawings, like reference characters refer to like parts throughout.
By reference to Figures 1, 2, and 3, it can be seen that the reel of the first embodiment of the 80 invention is formed of two wholly rigid reel members i and 2 each of which is substantially circular in cross section. Each of said members is shown as of substantially cylindrical form, although they may, if desired, beof other forms;'85 e. g., frusto-conical. Reel member I has a periphery formed of longitudinally extending radially projecting bar members 3, while reel member 2. has a periphery made up of longitudinally extending radially projecting bar members 4, the bar 40 members of the two reel members being alternately disposed so that the two reel members occupy substantially the same space. Each of the reel members is mounted for rotation about its own individual axis, the axes of the two reel 45 members being inclined from parallelism with each other in a manner which causes thread wound about the reel members to advance lengthwise thereof during rotation of said reel members.
In the illustrated embodiment of the invention, the reel members are mounted for rotation about axes which are disposed in inclined relation to each other in parallel planes.
In the embodiment of the invention under discussion, driving reel member I is concentrically 56 mounted on and for rotation with a drive shaft I journalled in a frame member 8 which, as shown in Figure 1, is provided with a flange I by means of which it is mounted as by bolts I on the frame 2 of the apparatus as a whole. Reel member I may therefore for convenience be called the concentric reel member. The driven reel member 2 is mounted on said frame member I for rotation about an axis displaced as above described from the axis of rotation of driving reel member I, wherefore driven reel member 2 may be called the eccentric reel member.
On drive shaft 5 is mounted a helical gear ll meshing with a helical gear i 2 on shaft I 3, which may be rotated by any suitable means (not shown). The reel drive shaft I is rotatably supported in frame member 8 by means of spaced anti-friction bearings I4 and I 5 which may conveniently take the form of ball bearings. The outer race of the bearing I4 is located in frame member 6 against a shoulder I 8 while the inner race of said bearing is positioned on drive shaft 5 on a finished portion l1, being located against shoulder ll. Thus hearing I I is disposed between shoulders I! and I8.
Bearing I 5, which is positioned at the supported end of frame member 0, is mounted with its inner race on finished portion I! of drive shaft I while -its outer race is located in a suitably finished bore 2| in frame member 8. A washer 22 is caused by means of a collar 24 located on drive shaft 5 to bear against the rear surface 23 of frame member 6. Thus drive shaft I is accurately located with respect to frame member I with the portion 25 thereof projecting from the unsupported end of frame member I.
In the embodiment of the invention shown in Figures 1 to 5, inclusive, concentric reel membe: I comprises a hub portion 26 held on portion 25 of drive shaft 5 against a shoulder 21 on said drive shaft by means of cap nut 22 threaded on the end thereof. Positive driving enga ement is provided by a pin 29 passing through said drive shaft which pin 29 engages a slot 30 at the rear of said hub member. Spaced supporting members 3| and 32, which may, as shown, be of substantially circular disc-like form, are rigidly affixed to said hub member 28, as by bolts 32. Bar members 3 of concentric reel member I are mounted in slots II on the eripheries of said sup ortin members if and 32, as shown in Figure 2. Said bar members, which are formed as in Figure 4. have a longitudinally extending portion and a portion 38 extendin radially toward the interior of the reel which latter portion is provided with shoulders 31 against which said discs M and 32 bear.
Each of the bar members I is firmly fixed to members 3! and 32 by means of taper pins 28 at at least one radial intersection of said bar members and each of members if or 32. Said pins serve to hold the bar members 3 firmly in said sup orting members 3| and 22 and to prevent radial movement of said bar members with respect to said discs. The holes for the pins 38 are preferably drilled and reamed in the initial assembly with the bar members in place. The bar members 3 are rovided with such radially extending portions 3 and longitudinally extending portions 35 in order that they may extend over and surround the supporting means for the bar members of the other reel member 2 without interference with the bar members or other parts of said other reel member.
In this embodiment of the invention, reel mem- 'slots 24 in their peripheries. in which slots are disposed the bar members of reel member 2. As in the case of bar members I, each of said bar members I is provided with shoulders 31 against which bear supporting members 28 and 40. Each comprises a longitudinally extending portion II and a radially extending portion 26 which permit the bar member to extend beyond the supporting means for bar members 3 of reel member I. Bar members 4 are shown as held in supporting members 20 and 40 by means of pins 38 at the radial intersections of said bar members and said supporting members in a manner similar to that described in connection with reel member I.
As shown in Figure 3, the supporting members 39 and ll are mounted on and spaced apart by a cylindrical sleeve ll which in effect forms the hub of reel member 2, the supporting members 3. and being recessed as shown for the purpose of locating them with respect to said sleeve. The inner supporting member 39 terminates at the interior bore of said sleeve for the purposes of assembly, while the outer supporting member ll extends inward and serves to aid in locating the reel member 2 and the anti-friction bearing 42 by means of which the reel member 2 is 1'0- tatably mounted on the frame member 8. Bolts 42 and nuts ll spaced at intervals around reel member 2 serve to clamp the supporting members 30 and ll together on the sleeve ll and against shoulders 21 on bar members 4, thus forming a rigid assembly of bar members I, members 3! and ll, and sleeve 42. A tubular member 45 surrounding each bolt 43 may be provided to protect the bolts 43 from processing media and to aid in spacing the members 39 and III.
In the embodiment of the invention shown in ligure 3, anti-friction bearing 42 comprises a roller bearing made up of an outer race 46 mounted in sleeve I and an inner race 41 mounted on a sleeve ll fixed to frame member 0, rollers 49 being disposed between said races. Rings 50, shown as disposed at both ends of said rollers 49, may form parts of the cage for spacing said rollers,- They may also serve to aid in sealing the bearing against the entrance of extraneous materials such as the processing medium or against the escape of lubricant from the bearing itself.
Said sleeve I. is rigidly fixed in the desired pomtion on frame member I by means of screw II. Disc-like member 52 is bolted to said sleeve 42 to hold the reel member 2 in position with respect to frame member 8' and also to protect the interior mechanism of the reel member. Reel member 2 is thus located endwisev on frame member 6 between shoulder 53 on sleeve II and member 52. If desired, "a disc 84 may be mounted at the end of the reel member 2 and a sleeve of reagent-resistant material 55 may be mounted on the rear portion of sleeve 48 to protect the rear of the reel from possible attack by the processing liquid.
Various other means than those described above may be employed to hold the bar members of each reel member in the spaced supporting members thereof.
Thus the slots in the supporting members in which the bar members are disposed may be of such shape that the bar members fitting therein are prevented from radial movement. This may be accomplished by making the slot of enlarged cross section .below the surface of the supporting member and forming the bar members so that they closely fit therein, whereby radial movement of the bar members with respect to the supporting members is eliminated. Thus in the embodiment shown in Figures 6 and 7, a dovetail arrangement is provided; that is, the slots 34' in each supporting member taper outward toward the bottom of the slot and the bar members 3' are provided with corresponding portions 56 which feed into said slots. Consequently, when each reel member is assembled, the supporting members are held against the shoulders 31 on the bar members'while radial movement of the bar members with respect to the supporting members is prevented by the dovetail joint.
Each of the reels shownas embodying the invention is of cantilever form; that is; it is supported from one end only and has the other end thereof unsupported so that thread can be wound on or unwound over the end of the reel.
In general, the operation of the reel is similar to that of the reel shown, described, and'claimed. in copending application Serial No. 652,089 for Winding reel, filed January 16, 1933, by Walter -F. Knebusch. The offset relation of the reel members causes the thread wound about the reel to be carried for half the circumference of the reel by the bar members of each set; that is, for one-half a revolution of the reel, the bar members of one reel member carry the thread, while for the other half of the revolution of the reel the bar members of the other reel member carry the thread. Thus as the reel rotates the thread is transferred from the bar members of one reel member to those of the other. The inclined relation of the bar members causes the thread to advance lengthwise of the reel, this because of the fact that the thread winding on each reel member from the other reel member travels at right angles to the axis of rotation of the reel member to which it passes.
The result of these operations is to advance the thread lengthwise of the reel in a plurality of substantially'helical turns the pitch of which is determined by the inclination of the axes between the reel members. In the reel of Figures 1 to 5, inclusive, for the direction of rotation indicated by the arrow in Figure 2, the thread will advance toward the unsupported end of the reel. This is advantageous since thus the benefits of the cantilever construction of the reel can be utilized to the fullest extent.
The reel of the embodiment of the invention shown in Figures 8 to 15, inclusive, is similar to that above described.
In this embodiment, the reel member la is mounted on drive shaft 5a which is journalled in frame member 6a. The reel member 2a is rotatably mounted on frame member 6a, the axes of rotation of said two .reel'members being offset from and inclined to each other, as is the case in the previously described embodiment. Drive shaft la is journaled in frame member 6a in antifriction bearings; e. g., the ball bearings a and Ila. The outer race of ball bearing Ma is mounted in frame member la against shoulder lid. The inner race of said bearing I la is located on drive shaft 5a, against shoulder I80. A collar 24a is mounted on drive shaft 6a to bear against the inner race of the other bearing I5a while the outer race bears against shoulder 51 in member 6a.
The drive shaft in, which is thus accurately located lengthwise of reel member to, may be driven by any suitable means such as a gear Ila.
Reel member la is mounted on the projecting portion 25a of drive shaft So. It comprises a hub member 26a mounted on projecting portion 25a which is held thereon against a shoulder 21a on driveshaft 50 by means of a cap nut 28a threaded on the end of said drive shaft. Positive driving engagement is provided between said hub member 26a and drive shaft 5a by a pin 29a passing through said drive shaft having its projecting portions disposed in a slot 30a in hub member 26a.
Asin the previously described embodiment of the invention, the bar members 3a of reel member la are supported by spaced supporting members 3 la and 32a which are mounted on said hub member 26a. Said hub member, which is shown to advantage in Figure 10, isprovided on its external surface with a plurality of recesses 58 engaged by corresponding lugs 59 on said supporting members 3la and 32a which are shown advantageously in Figure 13. Thus positive driving engagement is provided as between said hub member 26a and supporting members 3la and 32a.
In this embodiment of the invention, the spaced supporting members 3|a. and 32a are clamped; together by bolts 60 which are threaded at one end into inner supporting member 32a and pass through outer supporting member 3 la, being provided at their ends with cap nutslil.
As in the previously described embodiment of the invention, the bar members 3a are disposed in slots34a in the peripheries ofmembers 3m and 320., being rigidly held therein by means of pins 3811 at the radial section of said slots and and 12, the bar members thereof provided with enlarged portions 04 at the points where they contact with supporting members tie and 320.
As shown in Figures 8, 9, 11 and 12, bar members 3a are provided with raised portions, such as the button -like portions 65, at the points where they come into contact with the bar members 40 of the other reel member. Similarly, bar members la are provided with raised portions '5. Such raised portions are for the purpose of avoiding wear on other portions of the bar members due to sliding contact during operation of the pins 380 being provided to hold said bar members flrmly to said supporting members. As in the case of reel member la, a series of spaced bolts 80 disposed about reel member 2a serves to clamp supporting members "a and lla together, said bolts being threaded into inner member "a, passing through outer member a, and being adapted to be tightened by means of cap nuts I.
The rear portion of supporting member a may be formed with a sleeve portion I2 having one or more external flns 13 .thereon to assist in preventing liquid from reaching the interior of the reel from the rear thereof.
As appears from Figure 9 and from Figures 13 to 15, inclusive, this embodiment of the invention includes means for preventing any p liquid which may be applied to the reel from reaching the interior mechanism thereof. Such means comprise a plurality of overlapping annular flanges disposed on the adjacent inner faces of the inner supporting members 32 and "a of ,reel members In and 20. Member 320 is provided with an annular flange portion 14 which reel member 2a. .Reel member 394 is provided projects toward the supporting member "a for with a similar flange portion I5 which is directed toward supporting member 32a. Annular flange portion 11' is of smaller diameter than 5 annuiarflange member I5; together, said annular flange P rtions effectively obstruct the space between the reel members Ia and 2a against the entrance of liquid;
Each flange portion may be substantially 1c trough-shaped, as shown, to aid in preventing the passage of liquids. If liquid is applied to the thread on the reel, a large portion of any liquid which passes between reel members in and 2a is caught by the trough in annular flange portion 15 .15 and is discharged between the bar members on the lower portion of the reel. Any liquid which is not caught by said annular portion 15 is caught by the trough in annular flange portion 14 and is discharged from the lower portion of 2c the reel. Since these portions overlap, they effectively prevent the entrance of any liquid to the interior of the reel. Said annular flange portion thus comprises a labyrinth seal. While only two such flange portions are shown, one for each reel member, it is obvious that a large number may be provided.
In this embodiment of the invention, the disclike supporting member Ila is curved or dished, asshowninFigureQ,beingdisposedwithitsconvex side toward the unsupported end of the reel. This is advantageous because it increases the strength of the member Ma and because it makes it possible to dispose the cap nuts 28a and I in recesses 16 formed in the face of the member Sla, as shown in Figures 8 and 9. Therefore, no proiections are provided at the unsupported end of the reel around which thread being discharged from the reel, can entangle as, for example, in a the threading-up operation.
The reels above described are designed for operation over-long periods during which they are subjected to liquids. For this reason, the bearings are enclosed for protection against the entrance of processing liquids and sealing means are provided between the reel members to prevent the .e of liquid therebetween. Moreover, parts of the reels exposed to the processing liquids may be made or covered with suitable reagent-resistant materials. Thus, the parts indicated in heavy sectioning. such as the bar members, the supporting members for said bar members, the hub members on which said supporting members are mounted, the tubes sur- 5; rounding the through bolts which hold the supporting members together, the cap nuts therefor, etc., may be molded, cast, or cut of hard rubber, Bakelite, synthetic resins, or other materials resistant to the action of the processing liquids. 6|
As is apparent from the above description, reels embodying the present invention may be of very strong built-up constructions. This is particularly advantageous in the case of large reels, since it results in reductions in both cost and weight. Moreover, the reels of the present invention can be readily mbled by removing the nut at the end of the drive shaft, drawing the concentric reel member of! the drive shaft, and removing the member 52 or 52a. from the 71 unsupported end of the frame member 6 or a preparatory to drawing the eccentric reel member of! the frame member. Asembly of the reel may similarly be easily accomplished.
lflirthermore, since in the illustrated embodi- 7| ments of the invention the reel members are mounted on anti-friction bearings, the power required to drive the reels is low, which is advan-' tageous in plants for the continuous processing of thread wherein large numbers-of reels are employed. Such bearings reduce maintenance costs, since they may operate for long periods of .time without getting out of order and without shutdowns for lubrication of the reels, adjustments for wear, etc. Indeed, it has been found that if the anti-friction bearings are greasepacked at assembly, the reels will operate indefinitely with no attention to the bearings. Such advantages of anti-friction bearings are provided by the present invention in a reel of cantilever construction, which feature is of farreaching importance.
It is apparent that the embodiments of the invention above described are purely illustrative and that numerous modifications may be made therein without departing from the spirit of the invention. It is evident that the reels of the invention may be employed for various other uses than those above indicated and in particular for advancing strip materials other. .than thread. In the appended claims, the term thread is intended to include, besides thread, all materials capable of being wound and advanced by the reels of the present invention. It is intended that the patent shall cover, by suitable expression in the appended claims, whatever features of patentable novelty reside in the invention.
