  • Patent number: 5461849
    Abstract: A new and improved versi-rake attachment comprising a clamp adapted to be secured to a handle of a tool. Two apertures are formed on the clamp. Two thumb screws are adapted to be received through the apertures formed on the clamp. The two thumb screws function to secure or release the clamp from the handle of the tool. A plurality of small spikes are integral with the clamp. The small spikes function to grasp the handle of the tool and prevent the clamp from rotating. The device contains a bracket having a generally rectangular configuration. The bracket is secured to the outer surface of the clamp. Two apertures are formed on the bracket. The device also has a tool head portion having two apertures formed therethrough. The two apertures correspond with the two apertures formed on the bracket.
