Metallic reel and method

Abstract

A metallic reel construction wherein spokes (C) are welded at spaced locations directly to end plates (B) and to rims (A). The end plates receive the staves (D) that are directly and rigidly affixed thereto in spaced relation to provide a relatively small hub providing rigidity and yet being capable of receiving a large amount of flexible material. Threaded members (E) rigidly connect the rigid rim and hub end plate assemblies adjacent to the ends of the staves for speedy assembly permitting shipment while disassembled.

Description

This invention relates to rigid metal reels that are capable of speedy assembly for winding and for distributing flexible material. The reels remain disassembled for shipping and storage in a minimum of space preparatory to assembly for winding, storing, and dispensing flexible material.

BACKGROUND OF THE INVENTION

The prior art includes metallic reels utilizing centrally disposed metallic end plates to which spokes are welded on one end while the other end is welded to metallic rims. A number of radially spaced staves are loosely connected between opposed aligned spokes. The connection between the staves and the spokes is accomplished through the use of metal stirrups welded to the spokes providing a slot for receiving an end of each of the respective staves. These reels may be easily assembled but because of the loose fitting connections between the staves and the spokes, the assembled reels shimmy and do not provide stable supports for the flexible materials wound thereon. Because the staves are located remote from the centers of the rims, a relatively large drum is provided for receiving the flexible material for storage. This diminishes the amount of material that may be stored on the reel.

The prior art is further illustrated by U.S. Pat. No. 4,345,724 that discloses a structure similar to that described above. The reel of the patent utilizes a small central hub rather than an end plate so that even less support is provided for the spokes. The staves are spaced outwardly from the hub and attached loosely to the spokes by means of a receptacle and a cotter pin for maintaining the staves within the receptacles. Metallic reels constructed in accordance with the patent evidently provide even more flimsy constructions than the prior art discussed above.

More and more, reels are required to satisfy the increasing need for laying cables including fiber optic cables of the type utilizing a woven sheath for covering the cable fibers. Metallic reels constructed in accordance with the invention are especially useful in storing and dispensing woven sheaths for fiber optic cables of various closed configurations for retaining the fibers. The metallic reels are also especially useful for shipping flexible material of any sort including woven paper and plastic sheet material. It is especially important that such reels be rigid and stable in order to provide effective support for the flexible material and that the reel construction be capable of speedy assembly thus providing ease of storage and shipping to reel users when used.

It is important that the reels be light in weight and yet possess strength and rigidity to provide effective support when material is wound thereon so as to replace the heavy reels currently in the market place that are constructed of wood and plastic in a variety of configurations.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the invention to provide light weight metallic reels of substantial rigidity capable of speedy assembly and disassembly.

Another important object of the invention is to provide metallic reels avoiding the use of disposable wood and plastic reels.

Another important object of the invention is to provide a metallic reel that is quickly assembled and providing substantial rigidity with increased capacity for storing, shipping, and distributing flexible material therefrom.

Still another important object of the invention is to provide a rigid metallic reel wherein staves are rigidly connected directly upon a centrally disposed metallic end plate preferably of a hexagonal configuration, and wherein the spokes are also connected by spaced plug welds to the end plates. The end plates provide a means for readily spacing the staves wherein planer surfaces are provided on each side of vertical slots at the corners of the end plates on either side of respective spokes. The removable connecting members are preferably threaded body bolts of the type that include washers retained closely adjacent to the heads of the bolts to facilitate placement of the end of the staves on the inside of the end plates wherein tabs affixed at an end of the staves opposite the flat surfaces of the washers assure a sturdy and rigid connection. Threaded shanks on the bolts pass through the slots into the tabs. By shipping the reels while disassembled, considerable space is saved on the truck.

DESCRIPTION OF A PREFERRED EMBODIMENT

The drawings illustrate a metal reel for winding single and multi-layer material thereon for storage and delivery having a pair of spaced metal rims A for confining the material wound on the reel therebetween. A metallic hub end plate B is centrally located and aligned within each respective rim. A plurality of circumferentially spaced tubular metallic spokes are welded on one end to the rims and on the other end to respective hub end plates providing a rigid rim and hub end plate assembly. A plurality of tubular metallic staves D are rigidly connected on respective ends to a metallic hub end plate forming a hub assembly. Threaded members E connect the rigid rim and hub end plate assemblies adjacent to the ends of the staves. Thus, the rigid rim and hub end plate assemblies and the hub assemblies are rigidly connected by the threaded members for speedy assembly permitting shipment while disassembled, and quick assembly for use.

FIGS. 1 and 2 illustrate a metal reel constructed in accordance with the prior art wherein a pair of opposed metallic aligned rims are illustrated at 10 . The rims 10 are supported by circumferentially spaced spokes 11 that are welded to relatively small end plates 12 on one end and to the rims on the other end.

The end plates each have inwardly facing flanges 13 that serve as hubs for chucking the reel for winding. A number of spaced staves 14 are loosely secured on each end between the spokes 11 .

FIG. 2 illustrates the mode of attachment wherein the spokes 11 are provided with metallic stirrups 15 that are welded at each of the free ends as at 16 providing a slot 17 for insertion of downturned ends 18 of the respective staves 14 . The spokes 11 are illustrated in FIG. 2 as being welded at a single location 19 to an end plate 12 .

FIG. 3 illustrates a metallic reel constructed in accordance with the invention wherein the opposed rims A are provided with end plates B that are centrally located and welded at two spaced locations to the end plates. The welds are located in radially spaced holes illustrated at 20 in FIG. 5 by plug welds 20 a . It will be observed that in FIG. 4 , the end plates are preferably hexagonal with the spokes C being welded at the corners with vertical slots 21 being provided on each side to receive a threaded shank carried by the connecting members E as best illustrated in FIGS. 5 and 6 . As illustrated in FIG. 7 , the end plates have inwardly turned flanges illustrated at 22 that serve as hubs for chucking the reels for winding. Mandrels 23 serve as chucking members as illustrated in FIG. 7 .

The threaded connecting members are illustrated in FIGS. 5 , 6 , and 8 as including bolt heads 24 with partially threaded shanks at 25 . A portion of the shanks immediately adjacent the inside of the bolt heads 24 are not threaded (not shown) so as to receive washers 26 . Since the threaded portions 25 are of larger diameter than the unthreaded shank portions (not shown) adjacent the inside of the bolt head 24 the washer fitting thereon cannot be removed thus assuring during assembly that the washer is always carried adjacent the outside of the open upstanding slot 21 . Flat tabs 27 are welded as at 27 a across each end of the respective staves so as to be received outside and in alignment with open slots 21 . Since the flat or planer surfaces of the washers and the tabs are located on either side of the end plates B, a rigid connection is formed between the staves and the end plates. The tabs are provided with threaded holes 30 . By using an air wrench, single applications thereof are all that is necessary to secure the bolts.

A modified form of the invention is illustrated in FIG. 6 wherein square plugs 28 are inserted in respective open ends of the staves B and are fixed therein by deforming the tubular stirrups D on each of their four sides as at 29 or by welding (not shown). The plugs are provided with threaded holes 31 for receiving the threaded bolts.

FIG. 8 illustrates a modified form of the invention wherein a pair of closely spaced staves are secured between respective adjacent vertical slots 21 in the end plates B. The more closely spaced staves provides a stronger, more adaptable hub surface for receiving material wound thereon.

While a preferred embodiment of the invention has been described using specific terms for the several structural components, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
