  • Patent number: 5151005
    Abstract: An apparatus for collecting cans from a ground surface. The apparatus comprises a basket portion having a carriage pivotally attached thereto. A bearing mounted shaft extends transversely across said carriage, and a plurality of flexible discs are connected to said shaft. At least one carriage wheel is attached to said shaft and has an outside diameter greater than an outside diameter of the discs. The carriage may be locked in a non-operating position wherein the carriage wheel and discs are spaced from the ground surface, and the carriage may be pivoted downwardly to an operating position wherein the carriage wheels engage the ground surface. The discs flex outwardly from one another when a can is pushed therebetween so that the discs engage the can and move it toward the basket portion. A can disengaging finger is positioned between pairs of adjacent discs for disengaging the cans therefrom so that the cans are free to fall into the basket portion.
