An apparatus for gathering, picking up and carrying loose materials such as dirt, leaves, debris, trash, hay, ice, snow and other materials or objects consists of two grasping elements which each have shafts with grasping devices or heads at one end, and a coupling which joins their shafts. The grasping elements can be commercially available rakes or shovels. Loose materials are gathered and picked up by placing one hand on the shaft of each grasping element and drawing the heads together. The coupling is flexible and can be moved along the shafts of the grasping elements to change the manner in which the elements function together. When the coupling is positioned at the end near the grasping heads, the apparatus functions in the manner of a post hole digger. When it is positioned near the middle or far end of the shafts, the apparatus functions in the manner of rake tongs or tweezers tongs.

What is claimed is: 1. An apparatus for gathering, picking up and carrying materials comprising: a) two grasping elements which each have a shaft with a grasping head at one end; b) flexible coupling means which can be moved along the shafts of the grasping elements to connect them together while permitting each of the grasping elements to rotate along the axes of their shafts and to pivot with respect to each other so that the grasping heads can be brought together or moved apart from each other; c) wherein each shaft has a length of two to six feet; and d) wherein each grasping head consists of tines arrayed to form a rake. 2. An apparatus as in claim 1, wherein the shafts have a diameter of 0.5 to 3 inches. 3. An apparatus as in claim 1, wherein the coupling means consists of two loops that have diameters slightly larger than the diameters of the shafts to be connected and said loops are connected by a flexible linkage means having a length of one-fourth to four inches. 4. An apparatus as in claim 3, wherein the entire coupling means is molded of or cut from sheets of an inherently flexible material. 5. An apparatus as in claim 3, wherein the flexible linkage of the coupling means is made of a rigid material fabricated in the form of a chain to impart flexibility. 6. An apparatus as in claim 3, wherein the flexible linkage means is a band of flexible material. 7. An apparatus as in claim 3, wherein the loops of the coupling means contain clamping devices that permit them to be moved along the shafts to a desired position and then clamped there to prevent further unwanted movement. 8. An apparatus as in claim 3, wherein the coupling means is made from rubber. 9. An apparatus as in claim 3, wherein the coupling means is made from plastic. 10. An apparatus as in claim 3, wherein the coupling means is made from metal. 11. An apparatus for gathering, picking up and carrying materials comprising: a) two rakes which each have a shaft with a grasping head at one end; b) flexible coupling means which can be moved along the shafts of the rakes to connect them together while permitting each of the rakes to rotate along the axes of their shafts and to pivot with respect to each other so that the grasping heads can be brought together or moved apart from each other; and c) wherein each shaft has a length of two to six feet. 12. An apparatus as in claim 11, wherein the shafts have a diameter of 0.5 to 3 inches. 13. An apparatus as in claim 11, wherein the coupling means consists of two loops that have diameters slightly larger than the diameters of the shafts to be connected and said loops are connected by a flexible linkage means having a length of one-fourth to four inches. 14. An apparatus as in claim 13, wherein the entire coupling means is molded of or cut from sheets of an inherently flexible material. 15. An apparatus as in claim 13, wherein the flexible linkage of the coupling means is made of a rigid material fabricated in the form of a chain to impart flexibility. 16. An apparatus as in claim 13, wherein the flexible linkage means is a band of flexible material. 17. An apparatus as in claim 13, wherein the loops of the coupling means contain clamping devices that permit them to be moved along the shafts to a desired position and then clamped there to prevent further unwanted movement. 18. An apparatus as in claim 13, wherein the coupling means is made from rubber. 19. An apparatus as in claim 13, wherein the coupling means is made from plastic. 20. An apparatus as in claim 13, wherein the coupling means is made from metal. 21. An apparatus for gathering, picking up and carrying materials comprising: a) two shovels, for shoveling dirt, snow or other material, which each have a shaft with a grasping head at one end; b) flexible coupling means which can be moved along the shafts of the shovels to connect them together while permitting each of the shovels to rotate along the axes of their shafts and to pivot with respect to each other so that the grasping heads can be brought together or moved apart from each other; c) wherein each shaft has a length of two to six feet. 22. An apparatus as in claim 21, wherein the shafts have a diameter of 0.5 to 3 inches. 23. An apparatus as in claim 21, wherein the coupling means consists of two loops that have diameters slightly larger than the diameters of the shafts to be connected and said loops are connected by a flexible linkage means having a length of one-fourth to four inches. 24. An apparatus as in claim 23, wherein the entire coupling means is molded of or cut from sheets of an inherently flexible material. 25. An apparatus as in claim 23, wherein the flexible linkage of the coupling means is made of a rigid material fabricated in the form of a chain to impart flexibility. 26. An apparatus as in claim 23, wherein the flexible linkage means is a band of flexible material. 27. An apparatus as in claim 23, wherein the loops of the coupling means contain clamping devices that permit them to be moved along the shafts to a desired position and then clamped there to prevent further unwanted movement. 28. An apparatus as in claim 23, wherein the coupling means is made from rubber. 29. An apparatus as in claim 23, wherein the coupling means is made from plastic. 30. An apparatus as in claim 23, wherein the coupling means is made from metal. 31. An apparatus for gathering, picking up and carrying materials comprising: a) two grasping elements which each have a shaft with a grasping head at one end; b) flexible coupling means which can be moved along the shafts of the grasping elements to connect them together while permitting each of the grasping elements to rotate along the axes of their shafts and to pivot with respect to each other so that the grasping heads can be brought together or moved apart from each other; c) wherein each shaft has a length of two to six feet; and d) wherein each grasping head consists of shovel head that is fabricated from sheets of metal, wood or plastic and that extends along the axes of the shaft for three to eighteen inches and extends sideways equally on both sides of the shaft for a total wide of three to twenty four inches. 32. An apparatus as in claim 31, wherein the shafts have a diameter of 0.5 to 3 inches. 33. An apparatus as in claim 31, wherein the coupling means consists of two loops that have diameters slightly larger than the diameters of the shafts to be connected and said loops are connected by a flexible linkage means having a length of one-fourth to four inches. 34. An apparatus as in claim 33, wherein the entire coupling means is molded of or cut from sheets of an inherently flexible material. 35. An apparatus as in claim 33, wherein the flexible linkage of the coupling means is made of a rigid material fabricated in the form of a chain to impart flexibility. 36. An apparatus as in claim 33, wherein the flexible linkage means is a band of flexible material. 37. An apparatus as in claim 33, wherein the loops of the coupling means contain clamping devices that permit them to be moved along the shafts to a desired position and then clamped there to prevent further unwanted movement. 38.
