Abstract
A clamping mechanism that is particularly suited for use as an attachment to a skid steer loader or forklift. The clamping mechanism can grasp both regularly and irregularly shaped objects between a moving clamp and retractable paddles.
Claims16
A material clamping mechanism comprising:
- a clamping plate having first and second opposing edges ends, said clamping plate having a first planar surface in a first plane, said first plane having a first side and an opposing second side;
- a generally planar first paddle pivotably supported by said clamping plate for selective movement in a second plane generally perpendicular to said first plane and adjacent said first end of said clamping plate from a first open position where said first paddle is mostly on said first side of said first plane and a second closed position where most of said paddle is mostly on said second side of said first plane;
- an elongate clamping member pivotably supported by said clamping plate adjacent said second end of said clamping plate for arcuate movement about an axis generally parallel to said second plane from a position generally perpendicular to the clamping plate towards the surface of said clamping plate;
- said first paddle and said clamping member being pivotable through a power source.

In a skid steer loader having a boom and a boom faceplate, the improvement comprising:
- a clamping plate supported on said boom faceplate and having top, bottom and first and second opposing ends, said clamping plate having a first planar surface in a first plane, said first plane having a first side and an opposing second side;
- a generally planar first paddle pivotably supported by said clamping plate for selective movement in a second plane generally perpendicular to said first plane and adjacent said first end of said clamping plate from a first open position where said first paddle is mostly on said first side of said first plane and a second closed position where most of said paddle is mostly on said second side of said first plane;
- an elongate clamping member pivotably supported by said clamping plate adjacent said second end of said clamping plate for arcuate movement about an axis parallel to said second plane from a position generally perpendicular to the clamping plate towards the surface of said clamping plate;
- said first paddle and said clamping member being pivotable through a power source.
