Abstract
A multi-compartment paralleling reel that allows different sets of wire to be drawn from the paralleling reel independently of each other. The multi-compartment paralleling reel includes a plurality of independent compartments. Each independent compartment can store a set of wire. A shaft mounted through the plurality of independent compartments allows each independent compartment to rotate relative to the shaft and allows each independent compartment to rotate independently of the other independent compartments. Thus, each set of wire can be drawn from each independent compartment of the multi-compartment paralleling reel independently of the other independent compartments. This allows the different sets of wire, which may include wires that have different diameter sizes, to be drawn from the independent compartments at different rates of speed or the same speed, depending upon what is desired.
Description




BACKGROUND




1. Field of the Invention




The present invention relates to the mechanical arts. In particular, the invention relates to a multi-compartment paralleling reel for allowing a plurality of different sets of wire to be drawn from the paralleling reel independently of each other.




2. Description of Related Art




Standard paralleling reels are well known in the art. Generally, electrical contractors use standard paralleling reels to install feeder wire, as well as other types of wiring, during the construction or maintenance of structures requiring electricity, such as buildings. For example, feeder wire is used as main electrical wiring to feed the electrical panels of buildings and typically has a large diameter. Standard paralleling reels can be composed of one large compartment having a hub and a pair of opposed rings at the hub's ends, which stores a single set of wire (wrapped around the hub), or multiple compartments formed by a plurality of rings dividing up the hub into multiple compartments each of which stores a different set of wire (wrapped around the hubs, respectively). Often, the standard paralleling reel is rotatably coupled to a platform by being fixedly mounted to a shaft, which is in turn rotatably coupled to the platform. Also, the standard paralleling reel is often motorized to aid in the loading of wire.




In the multiple compartments case, a worker typically draws a wire, by hand, from each of the multiple compartments, to install the wires. The multiple compartments are typically fixed onto the shaft of the standard paralleling reel such that the multiple compartments rotate together in unison. Thus, the multiple compartments all turn at the same time and at the same rate of speed. Accordingly, the different wires are released at whatever rate of speed that the multiple compartments are turning at. Unfortunately, it is often desirable for the workers to be able to pull the various wires from the different multiple compartments independently of one another at different rates of speed.




Additionally, it is often desirable for the workers to be able to pull wires having different diameter sizes from the different multiple compartments at the same rate of speed. However, when the diameter size of wire in one compartment differs from the diameter size of wire in other compartments, the various wires having differing diameter sizes are released at different rates of speed, which results in a significant loss of efficiency for the workers who are trying to pull the wires out in unison.




In view of the above, it should be appreciated that there is a need for a multi-compartment paralleling reel having independent compartments that allows the independent compartments to rotate independently of one another such that workers can draw the different sets of wire from the independent compartments at differing speeds. Particularly there is a need for a multi-compartment paralleling reel to allow workers to simultaneously unload different sets of wire having different diameter sizes at the same rate of speed. The present invention satisfies these and other needs and provides further related advantages.




SUMMARY




The present invention discloses a multi-compartment paralleling reel that allows different sets of wire to be drawn from the paralleling reel independently of each other. The multi-compartment paralleling reel includes a plurality of independent compartments. Each independent compartment can store a set of wire. A shaft mounted through the plurality of independent compartments allows each independent compartment to rotate relative to the shaft and allows each independent compartment to rotate independently of the other independent compartments, respectively. Thus, each set of wire can be drawn from each independent compartment of the multi-compartment paralleling reel independently of the other independent compartments. This allows the different sets of wire to be drawn from the independent compartments at different rates of speed or the same speed, depending upon what is desired. Accordingly, workers can unload different sets of wire having the same diameter size, or different diameter sizes, from the multi-compartment paralleling reel, at a desired speed, independently of one another and the other sets of wire. For example, workers can simultaneously unload different sets of wire having different diameter sizes at the same speed.




In one embodiment, the multi-compartment paralleling reel is rotatably coupled to a platform and is connected to a motor. The multi-compartment paralleling reel may further include a reel securing bar that extends transversely through the independent compartments to secure the independent compartments to one another. In this embodiment, the reel securing bar is used to secure the independent compartments to one another when different sets of wire are loaded onto the independent compartments, respectively. For example, the motor can be used to turn the independent compartments to load the wire. On the other hand, the reel securing bar is removed when the wire is unloaded. This allows the independent compartments to rotate independently of one another about the shaft such that workers can draw the different sets of wire, possibly having different diameter sizes, from the independent compartments at a desired speed. For example, workers can simultaneously unload different sets of wire having different diameter sizes at the same speed. This results in a significant increase in efficiency for workers trying to unload wires having different diameter sizes in unison.

The present invention discloses a multi-compartment paralleling reel that allows different sets of wire to be drawn from the paralleling reel independently of each other. The multi-compartment paralleling reel includes a plurality of independent compartments. Each independent compartment can store a set of wire. A shaft mounted through the plurality of independent compartments allows each independent compartment to rotate relative to the shaft and allows each independent compartment to rotate independently of the other independent compartments, respectively. Thus, each set of wire can be drawn from each independent compartment of the multi-compartment paralleling reel independently of the other independent compartments. This allows the different sets of wire to be drawn from the independent compartments at different rates of speed or the same speed, depending upon what is desired. Accordingly, workers can unload different sets of wire having the same diameter size, or different diameter sizes, from the multi-compartment paralleling reel, at a desired speed, independently of one another and the other sets of wire. For example, workers can simultaneously unload different sets of wire having different diameter sizes at the same speed.





FIG. 1

is a perspective view of a multi-compartment paralleling reel according to one embodiment of the present invention. As shown in

FIG. 1

, a multi-compartment paralleling reel


10


is rotatably coupled to a platform


12


by a shaft


13


and can be connected to a motor


14


. As will be discussed, the multi-compartment paralleling reel


10


allows different sets of wire, which may include wires having different diameter sizes, to be drawn from independent compartments that rotate independently of one another about the shaft


13


, at different rates of speed or the same speed, depending upon what workers operating the multi-compartment paralleling reel desire.




The platform


12


includes a rectangularly shaped base


20


having a first pair of opposed members


22


and a second pair of opposed members


24


. Further, the rectangularly shaped base


20


includes a pair of cross-supports


28


mounted between the second pair of opposed members


24


. Four base supports


30


(only three shown) depend perpendicularly from the rectangularly shaped base


20


and are used to support the platform against the ground. A pair of triangular supports


32


and


34


extend perpendicularly from the rectangularly shaped base


20


. The triangular support


32


includes motor supports


33


to mount the motor


14


to the platform


12


. The motor


14


may be a portable drive unit such as those produced by WAMCO Inc. Also, extending perpendicularly from the rectangularly shaped base


20


is a reel securing bar storage


36


that can be used for storing a reel securing bar, which will be discussed later.




At the top end of each triangular support


32


and


34


, u-shaped pillow bearing shafts


40


and


42


, respectively, rotatably mount the shaft


13


to the platform


12


. The u-shaped pillow bearing shafts


40


and


42


may be connected to the triangular support by conventional means nut and bolt assembly, rivets, welding, etc. Each u-shaped pillow bearing shaft includes a type-2 pillow bearing (not shown), respectively, to rotatably couple the shaft


13


to the platform


12


. Additionally each bracket includes a bearing oiler hole


50


(only one shown) to allow oil to be applied to the type-2 pillow bearing to ensure smooth rotation of the shaft


13


and the multi-compartment paralleling reel


10


. The shaft


13


also includes a square motor shank


52


that is connected to the motor


14


. The motor


14


can rotate the shaft


13


and the multi-compartment paralleling reel


10


such that wire can be loaded onto the multi-compartment paralleling reel


10


.




The multi-compartment paralleling reel


10


includes a plurality of independent compartments


55


,


56


,


57


,


58


, and


59


and the shaft


13


to allow different sets of wire to be drawn from the multi-compartment paralleling reel independently of each other. Particularly, in this embodiment five independent compartments


55


,


56


,


57


,


58


, and


59


are shown. However, it should be appreciated that the multi-compartment paralleling reel


10


of the invention may have any number of independent compartments and this embodiment is only exemplary.




Each independent compartment includes a cylindrically shaped hub


62


and a pair of opposed rings


64


and


66


, respectively. Each independent compartment can store a set of wire. The set of wire is stored by being wrapped around the hub


62


between the opposed rings


64


and


66


. Each hub has two arbor holes


68


and


70


on each side (only two shown). A wire of a set of a wire can be looped through the arbor holes to fix the wire onto a hub. After fixing wires to hubs, the sets of wires can be loaded onto the hubs of the independent compartments, respectively, by the motor


14


turning the independent compartments of the multi-compartment paralleling reel


10


, in unison, to wrap the sets of wires around the hubs, respectively.





FIG. 2

is a partial sectional view of the multi-compartment paralleling reel illustrating different sized types of wire mounted within three independent compartments, respectively, according to one embodiment of the present invention. As shown particularly in

FIG. 2

, each hub


62


of each independent compartment can store a set of wire. For example, independent compartment


59


can store a smaller sized diameter wire


72


, independent compartment


58


can store a medium sized diameter wire


74


, and independent compartment


57


can store a larger sized diameter wire


76


.




The shaft


13


mounted through the plurality of independent compartments


55


,


56


,


57


,


58


, and


59


, respectively, allows each independent compartment to rotate relative to the shaft and allows each independent compartment to rotate independently of the other independent compartments, respectively. The shaft


13


extends transversely through aligned holes


80


and


82


contained within first and second sides


84


and


86


of each hub


62


, respectively. Moreover, the shaft


13


extends through bearings


88


and


90


contained within each hub


62


, near the first and second sides


84


and


86


, respectively. The bearings


88


and


90


of each hub


62


allow each independent compartment to rotate freely relative to the shaft


13


. Alternatively, bushings can be used in lieu of bearings. Also, as previously discussed, the shaft


13


rotatably mounts the independent compartments of the multi-compartment paralleling reel


10


to the platform


12


.




With the configuration of the multi-compartment paralleling reel


10


of the present invention, each set of wire can be drawn from each independent compartment


55


. . .


59


of the multi-compartment paralleling reel independently of the other independent compartments. Typically, during unloading, a worker draws or pulls the wire from the independent compartments for installation into a structure that needs electrical wiring, such as a building. The independent rotation of the different independent compartments allows different sets of wire to be drawn from the independent compartments at different rates of speed or the same speed, depending upon the desires of the workers pulling the wires from the independent compartments. Accordingly, workers can unload different sets of wire having the same diameter size, or different diameter sizes (e.g. wire sets


72


,


74


,


76


), from the multi-compartment paralleling reel, at a desired speed, independently of one another and the other sets of wire. For example, workers can simultaneously unload different sets of wire having different diameter sizes (e.g. wire sets


72


,


74


,


76


) at the same speed. This results in a significant increase in efficiency for workers trying to unload wires having different diameter sizes in unison as opposed to previous types of standard paralleling reels.




Referring to

FIG. 1

, the multi-compartment paralleling reel


10


further includes a reel securing bar


94


having a rectangular head


95


and a hollow shaft


96


that can be placed transversely through the independent compartments


55


. . .


59


to secure the independent compartments to one another. Particularly, the reel securing bar


94


can be placed through aligned holes


97


and


98


contained within the first and second sides of each hub


62


of each independent compartment, respectively.




The reel securing bar


94


is used to secure the independent compartments


55


. . .


59


to one another when different sets of wire are loaded onto the independent compartments, respectively. A wire of a set of wire can be looped through the arbor holes


68


and


70


of a hub


62


to fix the wire onto the hub. After fixing wires to hubs, the sets of wire can then be loaded onto the hubs of the independent compartment, respectively, by the motor


14


turning the independent compartments of the multi-compartment paralleling reel


10


together, in unison, the independent compartments being secured together by the reel securing bar


94


, to wrap the sets of wire around the hubs, respectively. On the other hand, the reel securing bar


94


is removed when wire is unloaded. The far end of the reel securing bar


94


, which has a hollow shaft


96


, can be placed over the reel securing bar storage


36


to store the reel securing bar.




When the reel securing bar


94


is removed, this allows the independent compartments


55


. . .


59


to rotate independently of one another, about the shaft


13


, such that workers can draw the different sets of wire, possibly having different diameter sizes (e.g. wire sets


72


,


74


,


76


), from the independent compartments at any desired speed (e.g. different speeds or the same speed). The weight and friction of the shaft keeps the shaft in a basically fixed position relative to the independent compartments such that the independent compartments can rotate freely about the shaft. For example, workers can simultaneously unload different sets of wire having different diameter sizes (e.g. wire sets


72


,


74


,


76


) at the same speed, which results in a significant increase in efficiency for workers trying to unload wires having different diameter sizes in unison.




The method of use and operation of the multi-compartment paralleling reel


10


, constructed as described, generally proceeds as follows.

FIG. 3

is a flowchart illustrating a process


300


for allowing a plurality of different sets of wire to be drawn from a paralleling reel independently of each other according to one embodiment of the present invention. First, each set of wire is stored within an independent compartment, respectively (block


302


). To accomplish this, turning to

FIG. 4

, which is a flowchart illustrating a process


400


for storing each set of wire within an independent compartment according to one embodiment of the present invention, the independent compartments are initially secured together (block


402


). Next, the different sets of wire are loaded onto each independent compartment, respectively (block


404


).




Particularly, as shown in

FIG. 1

, the reel securing bar


94


is placed through the holes


97


and


98


of the independent compartments


55


. . .


59


to secure the independent compartments to one another. A wire of a set of wire can be looped through the arbor holes


68


and


70


of a hub


62


to fix the wire onto the hub of the independent compartment. After fixing wires to hubs, the sets of wire can then be loaded onto the hubs of the independent compartments, respectively, by the motor


14


turning the independent compartments of the multi-compartment paralleling reel


10


together, in unison, to wrap the sets of wire around the hubs, respectively.




Continuing with reference to

FIG. 3

, to unload the wire, each independent compartment is allowed to rotate independently of each of the other independent compartments (block


304


) and each set of wire is drawn from an independent compartment independently of each of the other independent compartments (block


306


). Particularly, with reference also to

FIGS. 1 and 2

, the reel securing bar


94


can be removed from the independent compartments


55


. . .


59


allowing the independent compartments to rotate independently of one another, about the shaft


13


, such that workers can draw the different sets of wire, possibly having different diameter sizes (e.g. wire sets


72


,


74


,


76


), from the independent compartments at any desired speed. Accordingly, workers can unload different sets of wire having the same diameter size, or different diameter sizes, from the multi-compartment paralleling reel, at a desired speed (e.g. different rates of speed or the same rate of speed), independently of one another and the other sets of wire. For example, workers can simultaneously unload different sets of wire having different diameter sizes (e.g. wire sets


72


,


74


,


76


) at the same speed, which results in a significant increase in efficiency for workers trying to unload wires having different diameter sizes in unison.




While this invention has been described with reference to illustrative embodiments, this description is not intended to be construed in a limiting sense. Various modifications of the illustrative embodiments, as well as other embodiments of the invention, which are apparent to persons skilled in the art to which the invention pertains are deemed to lie within the spirit and scope of the invention.
