ADOLPH HART Arm 11m) United States Patent Q CLOTH WINDING DEVICE Adolph Hart, Mount Vernon, N. Y. Application July 18, 1955, Serial No. 522,713 11 Claims. (Cl. 242-55) This invention relates to cloth winding racks or frames. More particularly, the invention has reference to a rack of the type used as a spool on which long pile or nappy fabrics are wound and shipped.

It is conventional in the art to provide a rack of the type stated having a long core, on the opposite ends of which are secured cruciform frames the arms of which are each provided with a radial series of spaced hooks adapted to engage in the selvage edges of the fabric, so that on rotation of the spool, the fabric will be spirally wound upon the spool, with its several convolutions or windings spaced out of contact with one another to prevent injury to the nap or pile. A structure of this type is shown, for example, in U. S. Patent 2,356,787, issued to Edwin G. Hellyar on August 29, 1944.

In this and other patents, however, all the hooks are extended prior to winding of even the first or innermost convolution of the fabric, and consequently, since the width of the fabric must needs be greater than the distance between the hooks to permit the hooks to engage in the opposite selvage edges thereof, the hooks interfere with the winding of the fabric onto the rack.

The main object of the present invention, accordingly, is to provide a rack in which, at the start of the winding operation, all the hooks of each radial series except the innermost hooks will be retracted, so that the fabric being wound will not extend into the path thereof as the spool rotates during the winding, and in which the rotation of the spool is effective to automatically extend successively following hooks of each series, in a direction radially outwardly of the cruciform frames, with each hook being extended only as it is to move into position to engage in the fabric.

A further object of importance is to form the hook extending means as a spool supporting and rotating assembly, with which the shipping rack is detachably associated, so that when the fabric has been fully wound, the shipping rack can be separated from said assembly and shipped.

A further object of importance is to effect not only the automatic extension of the hooks during the winding operation, but also the automatic retraction of the hooks in a direction radially, inwardly of the spool or rack, as the fabric is unwound from the rack, in successively following order, again to locate the hooks out of the path of the fabric.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 7 is an enlarged perspective view of a stub shaft carrying the rack for rotation during the winding operation.

The invention may be appropriately considered as comprising two main assemblies, these being a rack-rotating and hook-extending assembly generally designated 8, and the rack proper, generally designated 9, on which the fabric F is to be wound. In use, at the location, such as the factory, at which the fabric is to be wound for shipment, a pair of the assemblies 8, disposed a distance apart in opposed relation sufiicient to support the opposite ends of rack 9, are bolted or otherwise fixedly secured to a supporting surface, the rack 9 being detachably connected at its opposite ends to the assemblies 8 for rotation thereby during winding of the fabric, and being thereafter disengaged from said assemblies and shipped, with the rack being returnable from its destination to the factory after the fabric has been unwound therefrom, for re-use.

Considering first the construction of the assembly 8, this includes a flat base 10 cast integrally with or otherwise fixedly secured to a vertically extending post or standard 12 and bolted to an associated supporting surface as at 14.

In the upper end portion of the post 12 there is formed a bearing opening in which is horizontally journalled one end of a stub shaft 16 having a non-circular axial projection 18 extending outwardly from the post'12. A hand crank, not shown, or any other stub shaft rotating means including a power driven pulley or the like, also not shown, is attachable to the projection 18' for the purpose of rotating the stub shaft during winding of the fabric.

Intermediate its ends, the stub shaft 16 is formed with a circumferential collar 20, engaging in a recess formed centrally in a large diameter disc 22, said disc having a circular center opening in which rotates the stub shaft 16. Bolts 24, spaced outwardly from the shaft-receiving openings of the posts 12 and disc 22, are extended through smooth-walled openings formed in the posts 12, and are threaded in recesses formed in the disc 22, to fixedly secure the disc to the inner surface of post 12. Since the collar 20 is engaged between the post and discs, axial shifting of the stub shaft is prevented.

Formed in the inner face of the disc 22, that is, the face confronting the adjacent end of the rack 9, is a continuous, spiraling cam groove 26, starting in closely spaced relation to the stub shaft 16 as shown in Fig. 2, and terminating at its outer end adjacent the periphery of the disc. In a preferred embodiment of the invention, a line extending radially of the disc 22 from the center thereof fully to its periphery, will intersect the groove 26 at nineteen equidistantly spaced locations, for the purpose, as will presently appear, of providing nineteen convolutions or windings of fabric F upon the rack. This number is, however, not critical to the invention, and in a commercial embodiment, more or fewer windings can be effected, as desired.

The particular formation of the spiraling groove is of importance, to provide for extension of the fabric supporting hooks at predetermined locations in the cycle of rotation of the rack. Referring to Fig. 2, each convolution of the spiraling groove has a portion 28 extending a through 270 degrees of a circle, the radius of which portion does not change throughout the 270 degree length of said portion, with said portion being concentric with the axis of rotation of stub shaft 16. The remaining portion of each convolution of the groove, however, which extends through the remaining 90 degrees of the circle, is eccentric to the axis of rotation of stub shaft 16. Said portion 30 at one end communicates with one end of the portion 28 of the convolution, but at its other end is spaced outwardly from the other end of portion 28, to merge into the portion 28 of the next convolution.

At its inner end, stub shaft 16 (see Figs. 1 and 7) is integrally formed with a non-circular, axial extension 32, which in the present instance, but not necessarily, is square in cross section, and at its free end, extension 32 has a lug or tongue 34 also of non-circular cross section, reduced in size relative to the extension 32 to define a shoulder 35 at the base of the tongue. Similarly, at the merger of extension 32 into the cylindrical portion of stub shaft 16, a shoulder 37 is defined.

With the exception of the stub shaft 16, the parts of the rack support assembly 8 so far described are stationary.

The rack support assembly includes, in addition to the stationary cam disc 22, a rotary, cruciform cam frame 36, having four radial arms angularly spaced 90 degrees apart from one another about said frame, and integrally connected at their inner ends to provide a center portion on the cam frame having a square opening receiving the stub shaft extension 32. Cam frame 36 is rotated in closely spaced relation to the grooved face of the cam disc 22 as shown in Fig. 1, with the cam frame engaging against the shoulder 37. Thus, on rotation of the stub shaft, the cam frame will rotate, traversing the grooved face of disc 22.

Formed in each arm of the cam frame is an elongated slot 38 extending longitudinally and centrally of the arm, and closed at its inner and outer ends, the slots extending substantially for the full length of their associated cam frame arms. Mounted to slide in the respective slots 38 are cams 40, said cams being guided radially of the cam frame during rotation thereof within slots 38, from inner positions adjacent the center of the cam frame, in which the cams are engaged are against the inner ends of the slots, to outer positions adjacent the free, outer ends of the cam frame arms, in engagement with the outer ends of the slots.

Considering the formation of each cam (one of which is provided for each slot), reference is had to Fig. 6, in which each cam is illustrated as including a block-like head having a beveled outer end surface 42 providing a cam surface, the surface 42 lying in a plane oblique to the plane of rotation of the cam frame, with the several cam surfaces 42 being disposed in planes converging to intersect the axis of rotation of the cam frame at a location spaced inwardly from the cam frame along the length of the rack 9.

Integral with the head of each cam is an elongated shank 44 of square cross section, the opposite side surfaces of which engage against the opposite side surfaces of the associated slot 38, to prevent rotation of the cams in the slots. The shanks 44, at their ends remote from the heads of the cams, are integral with cylindrical, axial extensions 46, engaged in the cam groove 26 of disc 22 and angularly spaced 90 degrees apart within the cam groove as shown in Fig. 2.

By reason of the construction so far illustrated and described, it will be apparent that on rotation of stub shaft 16, the cam frame will rotate, and the several cams 40, responsive to rotation of the cam frames, will move radially, outwardly within their associated slots 38, due to the engagement of the cylindrical extensions 46 of the cams in the cam groove of stationary disc 22. In the illustrated embodiment, and with the cams initially at the inner ends of the slots 38, nineteen turns of the cam frame will result in the cams moving to the outer ends of slots 38, due to the provision of nineteen convolutions in the cam groove 26.

It is further important to note that during each turn of the cam frame, the cams will not move radially, outwardly of the cam frame until the cam frame is in its final degrees of its turn or rotation cycle. During the movement of the cam frame through said final 90 degrees, each cam will travel radially, outwardly within its slot 38 a predetermined distance, while its cylindrical extension 46 is engaged in the eccentric portion 30 of the particular convolution of the cam groove in which the cam happens to be at the moment engaged.

Each of the four cams, in this connection, moves the predetermined radial distance outwardly in following order. This can be noted from Fig. 2, in which the extensions 46 are in the innermost convolution of the spiral groove, at the beginning of the winding operation, before the first rotation of the cam frame. As the cam frame begins to turn within its first 360 degree cycle, with the extensions 46 of the cam traveling counterclockwise in Fig. 2, that extension 46 shown in what may be appropriately termed the 6 oclock position in Fig. 2 will, during the first 90 degrees of said cycle, move radially, outwardly, a distance equal to the distance between adjacent convolutions of the cam groove 26. During the next 90 degrees of the cycle the extension 46 shown in the 9 oclock position will travel the mentioned radial distance. During the next 90 degrees the extension 46 shown at the 12 oclock position, having now moved to the 6 oclock" position, will be adjusted radially, outwardly within its slot 38 the specified distance. Finally, during the final 90 degrees of the single cycle the cam extension 46 shown at the 3 oclock position in Fig. 2, having now traveled counter-clockwise in Fig. 2 to the 6 oclock position, will move radially, outwardly within the associated slot 38.

The construction of the rack or spool 9 will now be described. This includes an elongated core 48 formed as a bar of square cross section. In the opposite ends of the core 48, axial recesses 50, of a cross section matching the tongues 34 of the associated rack support assemblies 8, are formed, and the tongues 34 engage in the recesses 50, thus to mount the rack 9 for rotation with stub shafts 16 and cam frames 36.

At this point, only the construction at one end of the core 48 will be described, it being understood that an identical construction is provided at the other end of the core 48, for association with a rack or spool support assembly 8 similar to that shown in Fig. 1.

Fixedly secured to the end of core 48 shown in Fig. l is a cruciform rack or spool end frame 52, the arms of which are integrally connected at their inner ends and are in line with the respective arms of the cam frame 36, in closely spaced relation to the cam frame arms. The end frame 52 is spaced from the cam frame a distance substantially equal to the overall length of the heads of the cams 40, as shown in Fig. 4.

The arms of the rack end frame have been designated at 54, and are each provided with a series of fabricengaging books 56, each series extending radially of the rack end frame for substantially the full length of the associated arm 54, a distance substantially equal to the length of slots 38.

Each book of a series (see Fig. 5) includes an elongated rigid wire shank terminating at one end in a curved hook portion, the hook portions being directed radially, outwardly of the axis of rotation of the rack 9, and having sharply pointed tips pointing toward the associated arm 54, as shown in Fig. 4.

At its other end, each book shank is threaded or otherwise fixedly connected to a base 58 formed as a rectangular block one end of which is rounded as at 60 to provide a cam surface engageable by the cam surface 42 of the associated cam 40. The base 58 of each hook is slidably mounted in a recess 62 of arm 54, said recess opening at one end toward the cam frame to expose the rounded end 60 of each hook base to action by the cam 40.

At its inner end, each recess 62 has an end wall apertured for slidable engagement of the hook shank therein, and between each base 58 and the end wall of the associated recess, a coil spring 64 is held under compression, to normally urge the hook to a position in which the pointed tip of the hook portion engages against arm 54, with the base 53 projecting out of recess 62 in the path of cam 40.

Initially, the parts will be in the position shown in Figs. 1, 3, and in full lines in Fig. 4. The innermost hooks of each series will be extended, due to the fact that the earns 40 will be at the inner ends of their slots 38, so as to cause the heads of the cams to hold the innermost hooks in extended positions.

One end of the fabric F to be wound is now engaged with those extended hooks provided in the rack end frames at each end of the rack that are in the 6 oclock" position, as shown in Fig. 3. The nappy surface of the fabric F is turned upwardly, so that it will face inwardly of the several windings of the fabric when the fabric is wound or coiled about the core 48.

Now, the stub shaft 16 is rotated, either manually or by power means, in a counterclockwise direction, viewing the rack and cam frame as in Fig. 3, as shown by the arrows. As each hook moves into the 6 oclock position, it will engage the associated selvage edge of the fabric, and will penetrate the same. Since the fabric is tensioned between the rack end frames at opposite ends of the core 48, the fabric will hold the hooks extended, once they have been extended by the earns 40.

As previously noted, during the first 360 degree cycle of rotation of the cam frame and rack end frame, the innermost hooks of each radial series of hooks will have been extended, due to the location of the cams 40 at the inner ends of slots 38. In this connection, during the first 90 degrees of the first cycle, that cam 40 which is in the 6 oclock position, that is, in engagement with the hook 56 which is the first one to have been engaged with fabric F to initiate the winding of the fabric, will move radially, outwardly within its slot 38, to the dotted line position shown in Fig. 4, in which position it will have extended that hook 56 next adjacent the one engaged with the fabric F in Fig. 3, at the end of the fabric. This hook, as a result, will be held in extended position during the remaining 270 degrees of the first cycle, so that as it moves, during the final 90 degrees of said first cycle, from the 9 oclock position in Fig. 3 to the 6 oclock position, it will engage in the edge of the fabric.

This continues, of course, throughout the remaining turns of the end frame, with successively following hooks, in a direction radially outwardly of the rack end frames, being extended against the restraint of their associated springs 64, so as to be in position to engage the edge of the fabric. At the same time, however, the hooks are not extended until after they have cleared the web of the fabric which will extend substantially horizontally outwardly away from the rack as shown in Fig. 3, during one cycle, and are to engage the fabric during the next cycle.

In this way, the fabric can be wound upon the rack without difiiculty, and without interference from extended hooks, thus to permit the winding operation to be carried out with far greater rapidity than is presently the case, and without danger of hooks engaging in the selvage edges of the fabric prior to the time at which it is actually desired that they so engage the fabric edges.

It will be understood that one of the two rack support assemblies 8 can be formed with short slots receiving the shanks of the hold-down bolts 14, said slots extending parallel to the length of the rack 9, so that after the fabric has been fully wound, the rack support assembly 8 at at least one end of the structure can be shifted outwardly a short distance to disengage its tongue 34 from 6 the adjacent end of the rack 9, thereby to permit the rack to be removed from the two supported assemblies 8 for shipment.

When the rack has arrived at its designation, and is mounted for free rotation upon a suitable support for unwinding of the fabric, as the fabric unwinds and is disengaged from successively following hooks, said hooks will automatically retract instantaneously by reason of expansion of their springs 64, so as to be thereafter out of the path of fabric web as it is pulled outwardly to unwind it from the rack. The rack can then, after the fabric has been completely moved, be returned to the factory, for reuse.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
