Nut gatherer and method of constructing same
A nut gatherer device includes a cage formed by a plurality of wires and a pair of hubs. Each hub includes first and second annular sets of spaced teeth, with portions of the wires secured in the radially-aligned spaces. In use, the wire cage is rolled on the ground into contact with a bulky object, such as a nut, so that the object forces the wires to separate and permit the nut to pass into the cage where it is retained until emptying.
1. A device for collecting objects from the ground, comprising:
a pair of hubs each comprising a first set of annular teeth and a second set of annular teeth that is spaced radially inward from the first set of teeth, wherein open spaces between the teeth in the first set of teeth are aligned with open spaces between the teeth in the second set of teeth; and
a cage formed from a plurality of circumferentially spaced wires extending between said pair of hubs, wherein each of the wires is received within one of the open spaces between the teeth in the first set of teeth and within one of the open spaces between the teeth in the second set of teeth in each of said pair of hubs.
2. The device of claim 1 , wherein a portion of each of the wires is received within one of the open spaces between the teeth in the first set of teeth and within one of the open spaces between the teeth in the second set of teeth in one of said pair of hubs, and a portion of each of the wires is received within one of the open spaces between the teeth in the first set of teeth and within one of the open spaces between the teeth in the second set of teeth in the other one of said pair of hubs.
3. The device of claim 1 , wherein each of said wires has a bowed middle segment and opposed end portions.
4. The device of claim 3 , wherein said opposed end portions of each of the wires are received within one of the open spaces between the teeth in the first set of teeth and within one of the open spaces between the teeth in the second set of teeth in each of said pair of hubs respectively.
5. The device of claim 3 , wherein said end portions project inwardly.
6. The device of claim 1 , wherein the first set of teeth is located around the periphery of said hub.
7. The device of claim 1 additionally comprising a retainer adapted to hold said wires in position between said teeth.
8. The device of claim 7 additionally comprising at least one fastener engaging said retainer to maintain said retainer in a fixed position.
9. The device of claim 7 additionally comprising a washer positioned between said hub and said retainer.
10. The device of claim 9 , wherein said washer is compressible.
11. The device of claim 7 additionally comprising a compressible washer positioned between said hub and said retainer.
12. The device of claim 11 , wherein said second set of teeth in at least one of said hubs presents an annulus which receives said washer.
13. The device of claim 1 additionally comprising a plurality of retainers adapted to hold said wires in position between said teeth.
14. The device of claim 1 , wherein said each of said hubs has an outer surface and an inner surface and wherein said first and second sets of teeth project from said inner surface of said hubs respectively.
15. The device of claim 1 , wherein each of said wires includes a straight leg portion between said bowed portion and said end portion, said straight leg portions being received in said open spaces between said teeth.
16. The device of claim 15 , wherein said straight leg portions present an angle of approximately 90° with said end portions.
17. The device of claim 1 , wherein each of said hubs further comprises an axial aperture to allow said device to be rotatably attached to a handle.
18. A method of making a nut gathering device, comprising:
providing a plurality of wires;
providing a pair of hubs, each comprising first and second annular sets of spaced teeth, said second set being spaced radially inwardly from said first set of teeth, the open spaces between said teeth in said first set being aligned with the open spaces between said teeth in said second set; and
inserting portions of said wires into said spaces in said hubs.
19. The method of claim 18 additionally comprising affixing a retainer to each of said hubs to secure said wires within said spaces.
20. The method of claim 19 additionally comprising placing a washer over said inserted wires between said hub and said retainer.
21. The method of claim 19 , wherein said affixing step comprises attaching said retainer to said hub using a fastener.
