Description
~ 1~5739 - 1. The invention pertains to dispensers for coiled
2. wire, and particularly relates to dispensing coiled wire
3. supported upon a pallet.
4. Wire is normally stored and transported while in
5. coils, and the coils may be wound on reels or spools, boxed,
6. banded, placed over spindles, or otherwise handled. Coils
7. of welding wire used to supply elcctric welding equi~ment
8. are often dispensèd rom coils. Welding wire can be most
9. economically purchased in large coils, but previously,
10. welding apparatus dispensers were not capable of handling
11. large welding wire coils, and consecluently, wire costs are
12. greater than they would be if coils weighing several hun-
13. dred pounds could be utilized. To handle such heavy coils
14. it is necessary that the same be placed upon material hand-
15. ling devices, such as a pallet, which may be readily lifted,
16. transported and positioned by a lift truck or similar
17. material handling apparatus.
18. It is known to dispense wire from a coil by means
19. of a guide rotatable about the coil axis, the wire being
20. fed through the guide and into a stationary eye or conduit.
21. Such devices include cover members which engage the upper
22. portion of the spool and brake means control over run of
23. the wire guide.
24. In the past, a coiled wire dispenser for welding
25. wire has not been available which could utilize large, eco-
26. nomical wire coils. Usually, it is necessary to transfer
27. the wire coil to specially built coil dispensing apparatus,
28. and this necessity to handle the coil has limited the coil ; 29. size as well as other handling and dispensing factors.
30. It is an object of the invention to provide a wire *
57~
1. coil dispenser which may be employed with pallet supported 2. wire coils directly, without necessitatin~ the need to 3. transfer the coiled wire from the pallet on which it is 4. shipped.
5. A further object of the invention is to provide a 6. coiled wire dispenser which may be directly installed upon 7. a conventional pallet, and wherein installation of the dis-8. penser tends to hold the wire coils on the pallet during 9. use and augments the relationship between the pallet and 10. its coiled wire load.
11. In the practice of thc invention the dispenser in-12. cludes a vertically oriented column having wire guide means 13. rotatably associated with the column upper end through 14. which the wire is removed from the coil exterior and fed 15. in the desired direction. The column upper end also in-16. cludes a cover engaging the coil upper surface and threads 17. defined upon the column receive nut means for forcing the 18. cover into firm engagement with the coil upper surface.
19. The lower end of the column includes a hook type 20. bracket having a horizontal portion which is received be-21. tween the lowermost horizontal slats of a conventional wood 22. pallet. The horizontal hook portion is of a vertical dimen-23. sion no greater than the vertical dimension of the lower 24. pallet slats and the hook may be readily placed between 25. the pallet slats and positioned as desired substantially 26. coaxial with the wire coil.
27. Tightening of the nut means simultaneously forces 28. the cover into engagement with the coil upper surface and

1. coil dispenser which may be employed with pallet supported 2. wire coils directly, without necessitatin~ the need to 3. transfer the coiled wire from the pallet on which it is 4. shipped.
5. A further object of the invention is to provide a 6. coiled wire dispenser which may be directly installed upon 7. a conventional pallet, and wherein installation of the dis-8. penser tends to hold the wire coils on the pallet during 9. use and augments the relationship between the pallet and 10. its coiled wire load.
11. In the practice of thc invention the dispenser in-12. cludes a vertically oriented column having wire guide means 13. rotatably associated with the column upper end through 14. which the wire is removed from the coil exterior and fed 15. in the desired direction. The column upper end also in-16. cludes a cover engaging the coil upper surface and threads 17. defined upon the column receive nut means for forcing the 18. cover into firm engagement with the coil upper surface.
19. The lower end of the column includes a hook type 20. bracket having a horizontal portion which is received be-21. tween the lowermost horizontal slats of a conventional wood 22. pallet. The horizontal hook portion is of a vertical dimen-23. sion no greater than the vertical dimension of the lower 24. pallet slats and the hook may be readily placed between 25. the pallet slats and positioned as desired substantially 26. coaxial with the wire coil.
27. Tightening of the nut means simultaneously forces 28. the cover into engagement with the coil upper surface and
29. draws the hook upwardly to produce a firm mechanical inter-
30. connection between the column and pallet. Thus, rotation 1. of the nut means firmly positions the column relative to 2. the wire coil and pallet, and the forces imposed upon the 3. coil by the cover tend to maintain the shape and configura-4. tion of the wire coil as it is depleted, and ~revents the 5. wire coil from shifting relative to the pallet.
6. The aforementioned objects and advantages of the 7. invention will be appreciated from the following descrip~
8. tion and accompanying drawings wherein:
9. Fig. 1 is an elevational view, partially in section, 10. illustrating a wire dispenser in accord ~ith the invention 11. as mounted upon a pallet, 12. Fig. 2 is a top plan view of Fig. 1, and 13. Fig. 3 is an enlarged, detail, elevational section-14. al view of the column hook as taken along Section III-III
15. of Fig. 1.
16. With reference to Fig. 1, a wire coil, such as of 17. welding wire, generally indicated at 10 is mounted upon a 18. conventional wood pallet 12. The coil 10 may weigh several 19. hundred pounds, and is normally strapped or banded to the 20. pallet for shipping purposes. The pallet includes a plu-21. rality of spaced parallel upper slats 14 nailed, screwed 22. or otherwise affixed to three primary wood base members or 23. elements 16 perpendicularly disposed to the slats 14. Such 24. material handling pallets also usually include lower parallel 25. slats 18 transversely disposed to base elements 16 and di-26. rectly located below slats 14.
27. The dispenser includes a vertically extending co-28. lumn 20 of cylindrical configuration having an upper end 29. 22 which is provided with exterior threads 24. The column 30. lower end 26 includes a hook bracket 28 welded thereto, ~ . , - .. .... .
ILB~'7~9 1. which will be later described in detail.
2. The column 20 includes a blind hole 30 coaxially 3. bored therein rotatably receiving the guide support shaft 4. 32.
5. A circular cover 34 rests upon the upper coils of 6. coil 10 and the cover consists of a plurality of radially 7. extending elements 36 affixed to a hub 38 ~nd reinforced 8. by a circular ring 40 and welded at their outer ends to 9. circular rim 42 which extends slightly beyond the peri-10. phery of the wire coil. A nut 44 threaded upon threads 24 11. may be rotated by hand]es 46, and the washer 48 engaging 12. the nut also engages the covcr hub 38 wherein tightening 13. of the nut 44 produces a downward force upon the cover 34.
14. The guide support shaft 32 supports a shaped con-15. duit wire guide 50 which has an outlet at 52 coaxial with 16. the shaft 32, and a wire inlet at 54 disposed adjacent the 17. wire coil periphery. Bracing rod 56 extends toward the 18. outer portion of the guide conduit 50 from the shaft 32, and 19. a braking member 58 formed of friction material such as 20. rubber, leather, or the like rotates with the guide and 21. engages cover rim 42 to function as a brake to prevent 22. overtravel of the guide as it is rotated during wire dis-23. pensing.
24. ~lollow bearing structure generally indicated at 60 25. is located at the upper end of the guide conduit 50 at 26. outlet 52 and supports the wire discharge conduit 62. Dis-27. charge conduit 62 is relatively stationary and dispenses 28. the wire entering inlet 54 in the desired direction, such 29. as toward the welding machine. The bearing structure 60 30. may take any conventional form, and it will be appreciated " ~_ ~ 1657~9 _, 1. that as the wire 64 is pulled from the discharge conduit 2. 62 the guide 50 will rotate about the axis of the column 3. 20 and guide the wire being removed from the coil into the 4. inlet 54.
5. The wire dispensing apparatus is mounted relative 6. to the coil 10 and pallet 12 by the hook bracket 28 which 7. is welded to the column lower end 26. The hook includes 8. a vertically extending portion 66, and a substantially 9. horizontally disposed portion 68 which extends below the 10. central pallet base element 16. As will be appreciated 11. from Figs. 1 and 3, the vertical dimension of the hook 12. portion 68 is no ~reater than the vertical ~imension of 13. the lower pallet slats 18 whereby the hook may be readily 14. inserted under the central base elemcnt 16 even though the 15. lower slats 18 are resting upon a solid floor. The hook 28 16. is of a width capable of being inserted between both the 17. upper and lower slats 14 and 18, Fig. 3, and it will be 18. appreciated that tightening of the nut 44 to force the 19. cover 34 into engagement with the coil 10 also imposes an 20. upward force on the hook to firmly engage the portion 68 21. with the associated base element 16. Thus, tightening of 22. the nut 44 provides an effective mechanical interconnection 23. between the wire dispensing column, cover, the wire coil 24. and pallet.
25. The wire dispenser construction, and particularly 26. the use of the hook bracket 28, permits the dispenser to 27. be installed merely by lowering the column through the cen-28. ter of a strapped wire coil. The hook portion 68 may be 29. inserted under the central base element 16 and the nut 44 30. tightened to firmly force the cover 34 against the coil.
I ~57~9 "_, 1. Thereupon, the banding straps binding the coil may be 2. cut, if they have not already been severed, and the dis-3. penser may be firmly installed prior to the coil being 4. released from its transport banding.
5. The forces impos~d u~,on the coiled wire by the 6. cover 34 tend to maintain the coil configuration during 7. use, and as many wire coils include an inner cylindrical 8. spool or other similar member which defines the coil length 9. the use of the cover aids in maintaining the coil confiyu-10. ration even until the coil is substantially depleted. In-11. stallation of the dispenser of the invention is readily 12. aceomplished by unskilled personnel, and the dispenser 13. strueture may be fabricated at relatively low cost.
14. It will be appreciated that various modifications 15. to the inventive eoneept may be apparent to those skilled 16. in the art without departing from the spirit and scope of 17. the invention.
