Abstract

A portable supporting apparatus for systematically unwinding conduit wire (Romex for example) protectively coiled for use in cardboard cartons of various sizes. It permits the wire to be pulled out and dispensed smoothly without twisting. One man can pull the wire up through walls and wherever else necessary without having to return to the carton to untwist kinks and unmanageable deformations. It comprises a pedestal-type stand, a rotatable carton supporting platform, and piloting and guard means on the post above the platform which guides the free end of the wire to govern it and minimize dispensing difficulties.

Claims

1. A supporting, unwinding and dispensing apparatus for a supply of electric wire coiled in a cardboard carton comprising a portable stand embodying a self-supporting normally horizontal base centrally provided with a rigid vertical post, a carton seating and supporting platform mounted for free rotation on a median portion of said post, said platform being spaced from and rotatable in a plane parallel to said base and having means for releasably clamping the respective corner portions of the carton and assisting in retaining the carton atop and for simultaneous rotation with said platform, and a guard operatively mounted on an upper end of said post and designed and adapted to govern and guide the free end of the wire as it is hand pulled and payed out of a discharge opening which is provided therefor in a top wall of said carton.

2. The apparatus defined in and according to claim 1, and in combination, a drum mounted on an upper portion of said post and interposed between a central axial portion of said platform and an underneath central portion of said guard.

3. The apparatus defined in and according to claim 2, and wherein said drum is cylindrical in cross section and is of a vertical height slightly greater than the depth of the carton so that an upper end protrudes above the level of the top wall of said carton.

4. The apparatus defined in and according to claim 2, and wherein said guard comprises a concavo-convex disc having its concave side facing upwardly and its convex side facing downwardly, and manually regulatable assembling means carried by an upper end of said post and removably clamping said disc atop a coacting upper end of said drum.

5. The apparatus defined in and according to claim 4, and wherein said disc is of a prescribed diameter larger than the diameter of the drum so that the outer marginal portion overhangs and projects evenly beyond the outer peripheral surfaces of said drum.

6. The apparatus defined in and according to claim 4, and wherein said disc is of a prescribed diameter larger than the diameter of the drum so that the outer marginal portion overhangs and projects evenly beyond the outer peripheral surfaces of said drum;

said assembling means comprising an internally screw-threaded socket member fixed atop said post, a screw having a shank screwed into the socket member, said screw having an upper end provided with a handling and carrying grip.

7. A supporting, unwinding and dispensing apparatus for a coiled supply of electric wire confined, as usual, in a packaging and protecting carton, said apparatus comprising a ringlike self-standing base having coplanar radial circumferentially spaced spokes, said base adapted to reside flatwise on a floor or similar support surface, an axial post having a lower end joined to and connecting inner ends of said spokes, a stationary collar surrounding and fixed to an elevated median portion of said post and having an outstanding ledgelike flange, an inverted hub-forming cup encircling the post and having a depending rim flange resting and turnable on and relative to said ledgelike flange and providing hub means, antifriction ball bearings operatively housed in said hub means, a carton seating and supporting reel providing a platform and embodying coplanar radial circumferentially spaced arms joined at inner ends to the rim of said cup, angle brackets adjustably and detachably mounted on the respective outer ends of said arms and adapted to retentively grip coacting corners of the carton when it is seated for use on the platform, a significant upper portion of said post extending above the level of said platform, and means carried by the extending upper portion of said post for assisting in dispensing and paying out the wire progressively and for unhampered remote controlled use by an electrician, whereby to speed up wire stringing requirements.

8. The supporting unwinding and dispensing apparatus defined in and according to claim 7, and wherein the aforementioned means which is carried by the extending upper end portion of the post embodies a cylindrical readily applicable and removable drum, said drum being provided with apertured end portions fitted over component portions of the post, said drum being of a vertical height greater than the depth of the carton in a manner that the upper portion is capable of extending through and beyond an opening which is cut in the upper wall of the carton, said means also embodying an attachable and detachable guard, said guard being of concavo-convex form and comprising a disc, said disc being of a diameter greater than the diameter of the upper end of the drum and having outer marginal edge portions overhanging the peripheral surfaces of the drum.

9. The supporting unwinding and dispensing apparatus defined in and according to claim 7, and wherein the aforementioned means which is carried by the extending upper end portion of the post embodies a cylindrical readily applicable and removable drum, said drum being provided with apertured end portions fitted over component portions of the post, said drum being of a vertical height greater than the depth of the carton in a manner that the upper portion is capable of extending through and beyond an opening which is cut in the upper wall of the carton, said means also embodying an attachable and detachable guard, said guard being of concavo-convex form and comprising a disc, said disc being of a diameter greater than the diameter of the upper end of the drum and having outer marginal edge portions overhanging the peripheral surfaces of the drum, and said means also including a handle and a screw-threaded shank and means for coupling the screw-threaded shank to a socket member on the upper end of the standard, and the upper end of said shank being provided with a handle.
