Abstract
A spool to facilitate drawing off of products from a wound coil of product, the spool comprises first and second disc like members having elongated central cylindrical hubs formed to interengage while leaving a central cylindrical spindle receiving passage therethrough so that with the hubs inserted into the center of the product coil from opposite sides of the coil and interengaged they span across the width of the coil. The interengagement of the hubs is such as to be maniputable to positively draw the members towards each other. Preferably the disc like members are injection molded plastic and are formed so that when they are drawn together they firmly grip only the innermost layer of the coil.
Description
SPOOL FOR COILED WIRE
FIELD OF THE INVENTI
This invention relates to the handling of coils of product such as outdoor electrical wiring, tubing and the like and, more particularly, to a spool on to which a coil of wound product can be mounted to greatly facilitate the drawing of the product off the coil.
BACKGROUND OF THE INVENTION
At present, such products as electrical outdoor wiring are wound layer upon layer like a spool of thread into a coil. The wound coils upon removal from their spools are strapped and then shrink wrapped in plastic for shipping. For ease of shipping, the external and internal diameters of the wound coils are maintained the same for a given size of product.
The customer upon receiving the shrink wrapped wound coil removes the shrink wrapping and cuts or removes the strapping and is then left to his own devices as to how the product can be drawn off the wound coil.
It is the object of the present invention to provide a very effective solution to this existing problem to thus enable the product to be drawn off the shrink wrapped wound coil with ease.
SUMMARY OF THE INVENTION
According to the invention, the solution to the problem resides in providing a two part spool on to which the shrink wrapped wound coil can be mounted. This two part spool comprises a first disc like member and a second disc like member having interengaging means for drawing the members together from opposite sides of the shrink wrapped wound coil. These members are formed so that the innermost layer of the coiled product is firmly gripped therebetween when they are firmly drawn together and they provide a central cylindrical passage therethrough to receive a spindle on which they can rotate as the layers of the wound product are drawn off from the wound coil commencing with the outermost layer According to a preferred form of the invention, the spool on which the coil of wound product is mounted comprises a pair of injection molded disc like plastic members adapted to be screwed together to close against the coil from opposite sides. Each of the members has a central cylindrical hollow elongated hub, an inner annular wall section sloping outwardly from the hub and an outer annular wall section connected to the perimeter of the inner wall section and extending outwardly substantially at right angles to the axis of the hub. The hub of one of the members has an internal thread while the hub of the other of the members has an external thread threadable into the hub of the said one section whereby the members can be screwed together to bring the outer edges of the inner annular wall sections into gripping engagement with the innermost row of the coiled product whereby a spindle sleeved through the interconnected hubs enables the spool to freely rotate as product is drawn off commencing with the outermost layer.

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED
EMBODIMENTS OF THE PRESENT INVENTION
Figure 1 is a sketch illustrating a wound coil of product such as outdoor electrical wiring or the like, generally designated at 1, which is secured by strapping 2 and then enclosed shrink wrapped plastic 3.
In the customer's hands, the shrink wrapping would be pierced and the strapping 3 removed as by cutting with scissors 4 at which time the wound coil of product is ready to be mounted on the spool of the present invention which comprises two separate disc like members 5 and 6 as illustrated in Figure 3.
Figure 4 illustrates the relationship of the two disc members 5 and 6 after they have been assembled with the coil wound product. As seen in Figure 4, the disc like member 5 has an elongated central cylindrical hub 7 which is internally threaded with threads 8. Hub 7 has an outer end 9 and an inner end 10.. Connected to the hub 7 adjacent to the inner end 10 is an inner annular wall section 11 which slopes outwardly to its periphery 12. Connected to the periphery 12 of the inner annular wall section 11 is an outer annular wall section 13 which extends substantially perpendicular to the axis of the hub 7.
The disc like member 6 similarly has an elongated hollow hub 14 which is somewhat longer than hub 7 of member S. Hub 14 is externally threaded with threads 15 extending forwardly from a point 16 at the inner side of member 6 to its outer end 17. Secured at the inner end of the threading 15 is an inner annular wall section 18 that slopes outwardly from hub 14 to its periphery 19.
Attached to the periphery 19 of the inner annular wall section 18 is an outer annular wall section 20 which is substantially at right angles to the axis of the cylindrical hub 14.
As will be seen from Figure 4, as the hub 14 of the disc like member 6 is threaded into the hub 7 of disc like member 5, the disc members 5 and 6 will be drawn together until the opposing perimeters 12 and 19 of inwardly sloping wall sections 11 and 18 firmly engage the inner row 21 of the coiled wound product.
It will be understood that it is not necessary to totally remove the shrink wrapped covering of the coiled wound product as the hubs 7 and 14 can be punched through the plastic of the shrink wrapping as they are threaded together.
As seen from Figure 5, which shows member S and 6 ready for assembly, both the inner annular walls 11 and 18 and the outer annular walls and 20 are provided with openings 22 to save on material and reduce weight.
These openings preferably have surrounding flanges 23 to provide reinforcement.
Figure 6 is a perspective view illustrating the inner side of member S, the outer side being shown in Figure 5.
Figure 7 is a perspective view of the outer side of member 6, the inner side being shown in Figure 5.
As will be seen from Figure 7, the hub 14 at the outer side of member 6 is grooved to in effect provide teeth 24 by means of which the spool comprised by the screwed together components 5 and 6 can be rotated about a spindle, eg. a bar or pipe sleeved through hubs 7 and 14 by a gear (not shown)..
Figure 6 is a perspective view of the rear or inner side of the left hand disc member of Figure 5;
Figure 7 is a perspective view of the front or outer side of the right hand disc shown in Figure 5.

While a preferred form of the invention has been shown and described, it will be understood that various modifications may be made without departing from the scope of the appended claims.
