Abstract

A rack for rotatably mounting one or more wire dispensing spools. A set of four rollers extend horizontally between a pair of spaced parallel side walls and are positioned in a substantially square-shaped configuration and rotatably mount and retain the spools therebetween. Each roller includes a cylindrical low friction plastic sleeve mounted on a center support rod or axle. A plurality of spacers separate the sleeve into a plurality of sleeve sections allowing the spools to rotate independently of each other without affecting the rotation of adjacent spools. A top roller of each set is spring biased and moves horizontally within a pair of aligned slots formed in the spaced side walls allowing the spring biased roller to move horizontally toward and away from the other top roller of each set enabling the spools to be easily inserted or removed from the rack. Front and rear wheels and a handle allow the rack to be used as a cart to transport the spools and other equipment and materials to and from the work site. In a second embodiment the rack may be hand carried and contain only one four roller set.

Claims

1. A rack for rotatably supporting one or more spools including:

a frame which includes at least two spaced side walls;

a pair of spaced top rollers and at least one bottom roller spaced below said top rollers, said top and bottom rollers extending between the two side walls for holding at least one spool in a storage zone located between said rollers;

spring means for biasing one of the top rollers towards the other of said top rollers; and

means mounting the said one top roller for allowing said one top roller to move with respect to said other top roller and overcome the biasing of the spring means to change the spacing between said top rollers for inserting and removing a spool into and from the storage zone.

2. The rack defined in claim 1 including a spool;

in which a plurality of pairs of aligned holes are formed in the side walls; and

in which a rod is mounted in an aligned pair of said holes and extend between said side walls for rotatably mounting said spool between the side walls.

3. The rack defined in claim 1 in which certain of the rollers includes a rod covered by a cylindrical low friction plastic sleeve.

4. The rack defined in claim 3 in which said certain rollers each includes a plurality of circular spacers mounted on the rod dividing the low friction plastic sleeve into a plurality of sleeve sections.

5. The rack defined in claim 4 in which certain of the sleeve sections are approximately seven inches in length and certain others of said sleeve sections are approximately three and one-half inches in length.

6. The rack defined in claim 4 in which the circular spacers are annular washers mounted concentrically on the rod.

7. The rack defined in claim 1 in which the spring means includes a pair of tension springs, each of which is fastened to opposite ends of each of the top rollers.

8. The rack defined in claim 1 including a plurality of wheels mounted on the frame for movably mounting the cart and a handle for movement of the rack on said wheels.

9. The rack defined in claim 8 in which the handle is U-shaped having a pair of legs extending along the side walls of the frame with said spring means being located within said legs to conceal said spring means.

10. The rack defined in claim 8 in which at least one of the wheels includes a braking mechanism engageable with said one wheel for braking said wheel for keeping the rack stationary while in use.

11. The rack defined in claim 1 in which a pair of bottom rollers are positioned between the side walls;

and in which top and bottom roller pairs are mounted in a square-shaped configuration with one roller at each corner to hold the spools in the storage zone.

12. The rack defined in claim 11 in which said rack includes only one set of spaced top and bottom rolls;

and in which a handle is mounted on the two side walls of the frame for manually lifting and carrying said rack.

13. The rack defined in claim 11 including a spool having a pair of end flanges movably supported on the spaced bottom rollers.

14. The rack defined in claim 13 in which the top two rollers are adapted to engage the spool end flanges to trap the spool within the storage zone.

15. In combination at least one spool having a pair of spaced annular flanges and an intervening hub, and a rack for rotatably mounting said spool for dispensing material wound about said hub, said rack including:

a frame having at least a pair of spaced side members;

a plurality of rods including a pair of upper rods and at least one lower rod providing a rod set extending between the side members and forming a zone between said rods for rotatably mounting and trapping the spool therein with the lower rod engaging the spool flanges and supporting the spool within said zone and the upper two rods loosely trapping the spool in said zone as the spool is rotated for dispensing material therefrom; and

means movably mounting one of the upper rods for changing the spacing between said upper two rods for inserting and removing the spool into and from the storage zone between said rods, said mounting means includes a pair of opposed slots formed in the side members for movably supporting opposed ends of said one upper rod and spring means for biasing said one upper rod towards the other of said upper rods.

16. In combination at least one spool having a pair of spaced annular flanges and an intervening hub, and a rack for rotatably mounting said spool for dispensing material wound about said hub, said rack including:

a frame having at least a pair of spaced side members;

a plurality of rods including a pair of spaced upper rods and at least one lower rod providing a rod set extending between the side members and forming a zone between said rods for rotatably mounting and trapping the spool therein with the lower rod engaging the spool flanges and supporting the spool within said zone and the upper two rods trapping the spool in said zone as the spool is rotated for dispensing material therefrom; and

mounting means movably mounting one of the upper rods for changing the spacing between said upper two rods for inserting and removing the spool into and from the storage zone between said rods, said mounting means including a pair of opposed slots formed in the side members for movably supporting opposed ends of said one upper rod, and spring means for biasing said one upper rod towards the other of said upper rods.

17. A rack for rotatably supporting at least one spool including:

a frame which includes spaced side members;

at least three spaced rods including a pair of spaced upper rods extending between the side members and forming a zone between said rods for rotatably mounting and trapping the spool therein;

mounting means for movably mounting one of said upper rods with respect to the other of said upper rods for changing the spacing between said upper rods to permit the spool to be inserted into and removed from the zone; and

spring means for biasing the said one rod towards the other of said upper rods enabling the spool to be inserted into and removed from said zone.
