Abstract
A spool assembly for dispensing a coil of wire, such as Romex, wherein a first cylindrical core having top and bottom ends, and provided with a circular radially extending flange secured to the bottom end, is provided in combination with a second cylindrical core having top and bottom ends and a circular radially extending flange secured to the top end of this second core. The first and second cores are threadably engageable with each other for thereby drawing the flanges towards each other to form a spool with the Romex coil retained in the spool assembly. A core tail end retainer is provided on the first core to retain the tail end of the wire coil and a clamping mechanism is provided on the second core for engaging the core tail end of wire retained in the afore-described retainer in clamping engagement when the cores are fully threadably engaged. A hand grip is also provided and is slidably received in the core assembly for axial rotation of the spool assembly thereon for easy hand dispensing of the Romex coil, and a removeable center core is also provided to permit rotation of the spool assembly on a shaft.
Description
- The present invention relates to a spool assembly and to the dispensing of coiled wire from the spool.
- In the field of commercial and residential electrical wiring, Romex wire is shipped in coils from the factory to retail and wholesale electrical supply houses in a thin clear plastic sheet or a cardboard box. The Romex is generally provided in 250 foot rolls or less for number 14-2 or number 12-2 Romex,
number 14 ornumber 12 American Wire Gauge (AWG) with two conductor wires plus a ground wire. - The factory container is adequate for distribution to the consumer, but provides a very inadequate or poor dispensing device. The 250 foot coil acts similar to a spring that needs to be straightened out, and without special care in handling, it can turn into a ball of coiled knots and kinks. This is because the wire coil is presented whereby it must be pulled from the side of the coil.
- Accordingly, it is a principal object of the present invention to provide an apparatus for efficiently and effectively dispensing the coiled Romex, or other wire.
- The dispensing apparatus of the present invention for dispensing a coil of wire is provided in the form of a spool assembly which is comprised of a first cylindrical core having top and bottom ends with a circular radially extending flange secured to the bottom end of the core, and a second cylindrical core having top and bottom ends with a circular radially extending flange secured to the top end of this second core. The first and second cores are threadably engageable with each other for thereby drawing the flanges together toward each other to form a spool with the unpackaged coil of wire retained between the flanges.
- A retaining mechanism is provided on the first core for retaining a core tail end of a wire coil to be retained in the spool, and a clamping mechanism is provided on the second core for engaging the core tail end of wire that is retained in this retaining mechanism in clamping engagement when the cores are fully threadably engaged.
- In a preferred embodiment, the second core has internal threads threadably engageable with external threads on the first core for providing the threaded engagement and the bottom end of the second core provides the clamping mechanism. This bottom end of the second core may include a series of teeth for engaging a core tail end of the wire retained in the aforesaid retaining mechanism. The retaining mechanism for the core tail end may in one embodiment take on the form of a wedged shaped groove for initially retaining a core tail end of the wire coil.
- The spool assembly is preferably constructed of plastic, as by injection molding.
- The inner core end of the role of Romex is inserted and retained in the wedge shaped groove for initially retaining the core tail end of the wire coil. This is done when the unpackaged roll of Romex is initially placed over the first cylindrical core. Thereafter the second cylindrical core is threadably engaged with the first cylindrical core and screwed thereon to bring the flanges together and thereby sandwich the Romex coil between the spool flanges until the bottom end of the second core engages the captured core tail end with the series of teeth to thereby clamp the coil core tail end in the retaining mechanism provided in the first cylindrical core.
- Accordingly, the factory roll of Romex can be unreeled from the Romex dispenser of the present invention very easily with no twists, kinks or knots in the wire by grasping the outer core end of the Romex end spooling it off the spool assembly of the present invention.
- A hand grip for the spool assembly of the present invention may also be provided whereby the handgrip is slidably received in the cores for axial rotation of the spool thereon whereby one may hand dispense the coiled wire by gripping the handgrip with one hand and with the other hand pulling the Romex off the roll or coil as the spool assembly of the present invention rotates on the handgrip.
- Once the Romex is cut to length, the excess cable can be recoiled back onto the remaining coil of Romex and the free end of the Romex can be inserted through one of four holes provided in an outer flange of the spool assembly, pulled tight and there bent to retain the coil on the spool assembly.
- In addition, footage indicators are also preferably provided on the inner side of at least one of the flanges so that one can precisely estimate the amount of Romex remaining on the spool assembly.
- The spool assembly of the present invention is constructed of materials that are extremely light in weight, yet will be very affordable and provide the user with a durable tool that can be used for many years.
- Other objects and advantages appear hereinafter in the following description and claims. The accompanying drawings show, for the purpose of exemplification, without limiting the invention or the appended claims, certain practical embodiments of the present invention wherein:
-
FIG. 1 is an exploded front view of the spool assembly of the present invention illustrated in an unassembled condition; -
FIG. 2 is a view in vertical mid cross section of the spool assembly shown inFIG. 1 illustrated as being in a partially assembled condition with an unpackaged coil of Romex wire contained therein; -
FIG. 3 is a top view of the spool assembly shown inFIGS. 1 and 2 in assembled condition; -
FIG. 4 is a top view of the lower portion of the spool assembly shown inFIG. 1 as seen along section line A-A; -
FIG. 5 is a sectional view seen along section line B-B ofFIG. 2 illustrating the spool assembly ofFIG. 2 fully assembled with a coil of 12-2 Romex contained therein and with the inclusion of a hand grip, the hand grip being shown in mid cross section; -
FIG. 6 is a top view of the hand grip shown in conjunction with the spool assembly as seen inFIG. 5 and as seen along section lines C-C ofFIG. 5 without the inclusion of the spool assembly itself in order to provide an unobstructed top view of the hand grip; -
FIG. 7 is a bottom view of the bottom portion of the spool assembly shown inFIG. 1 with a removable center core inserted for supporting the spool assembly for rotation on a shaft; and -
FIG. 8 is a view in mid cross section of the assembly shown inFIG. 7 as seen along section line D-D and with the center core shown unsectioned and in the process of being inserted. - Referring to
FIGS. 1 through 4 , thespool assembly 10 of the present invention is comprised of a firstcylindrical core 11 having top andbottom ends flange 14 secured tobottom end 13, and a secondcylindrical core 15 having top andbottom ends flange 18 secured totop end 16. First andsecond cores male threads 20 onfirst core 11 and matingfemale threads 21 onsecond core 15 for thereby drawingflanges tail end retainer 22 is provided onfirst core 20 for retaining acore tail end 23 of a Romexwire coil 24 retained in thespool assembly 10. - The
core tail end 23 of thecoil 24 is inserted and pressed intoretainer 22 for temporary retention.Retainer 22 has a wedge shapedchannel 19 therein to assist in temporary retainment and confinement of thetail end 23. A coretail end clamp 25 is provided on thebottom end 17 ofsecond core 15 for engagingcore tail end 23 confined inretainer 22 in clamping engagement when thecores tail end clamp 25 is provided with a series ofteeth 26. When the Romexcoil 24 is not being uncoiled onspool assembly 10, theouter tail end 26 may be passed through one of the fourretainer passages 27 provided insecond flange 18 and thereafter bent over to retain this free end and thereby prevent accidental unwinding of thecoil 24 in storage. - As is illustrated in
FIGS. 5 and 6 , ahand grip 28 is slidably received within and throughcores spool assembly 10 thereon for hand dispensing of the Romex 24.Hand grip 28 slidably rides against the innercylindrical surface 30 offirst core 11 on upwardly protrudingslide runner ribs 31 which have curved upper surfaces contoured to fit the inner curvature ofcylindrical surface 30. - In order to retain the
hand grip 28 on thespool assembly 20,core 11 is provided with annular axially extendingribs 32 and thehand grip 28 is provided with opposed in turned interlockingfinger flanges 33 which ride over top of axially extendingribs 32.Hand grip 28 is secured to thecore 11 of the first cylindrical core at the factory for permanent retention. Accordingly, Romex 24 is dispensed from thespool assembly 10 with no twists, kinks, or knots as it unreeled from thespool assembly 10 by grasping the slidinghand grip 28 with one hand and with the other hand pulling the Romex off thecoil 24 thereby causing thespool assembly 10 to rotate on thehand grip 28. Once the desired length is unreeled and cut off, the excess Romex 24 is recoiled back onto theremaining coil 24 and thefree end 26 is inserted through one of thepassages 27 and bent over for retention. - In addition, as is illustrated in
FIGS. 2 and 4 , theinside 40 offirst flange 14 is provided with inner raised ribfootage marker rings 41 so that the user will know the approximate footage of Romex remaining on thecoil 24. - The
spool assembly 10 is preferably manufactured of plastic as, for example, by injection molding so that it is lightweight and will not rust and is durable and therefore also reusable. - Referring next to
FIGS. 7 and 8 , aremovable center core 42 is illustrated which is removably retained within thefirst core 11 and is provided with acenter bore 43 therethrough for axial rotation of thespool assembly 10 on a shaft (not shown) for dispensing of Romex or other wire therefrom. Thecenter core 42 is circular for mating and insertion into the internalcylindrical surface 30 ofcore 11. Insertion is accomplished by inserting thecircular center core 42 into the cylindrical interior ofcore 11 in the direction as indicated byarrow 44. - The inside
circular perimeter end 45 ofcenter core 42 is provided with four equally spacedflexible fingers 46, each having outwardly protrudinglips 47 for flexibly riding over and then catching theouter surface 48 ofannular rib 49 provided on theinner surface 30 ofcore 11. Once fully engaged thecenter core 42 is retained within thecore 11 and cannot be removed unless and until thefingers 46 are flexed inwardly so that thelips 47 thereof will clearrib 48 and permit withdrawal of thecentral core 42. In this embodiment thespool assembly 10 with its fully insertedcenter core 42 may then be mounted on a shaft for rotation to permit dispensing of Romex or other wire coiled on theassembly 10. This embodiment is particularly useful for larger spools of Romex which are too heavy for hand dispensing. - In the embodiment shown in
FIGS. 7 and 8 ,spool assembly 10 is illustrated without the inclusion of thehand grip 28 shown inFIGS. 5 and 6 . However, it should be realized that theremoveable center core 42 may be adapted to also be received within the core of thespool assembly 10 provided with thehand grip 28. This is accomplished by providing thecenter core 42 with a side segment thereof removed to provide clearance for thehand grip 28 shown inFIGS. 5 and 6 . Accordingly acenter core 42 may be utilized with thespool assembly 10 which includes or does not include ahand grip 28 for rotation of the spool assembly on a shaft (not shown).
