ABSTRACT:

FIELD OF THE INVENTION
This invention relates generally to clamps for power tools and, more particularly, to a clamp that is easy to install on the power tool and to adjust against a workpiece.
BACKGROUND OF THE INVENTION
When cutting a workpiece on a power tool, such as a miter saw, chop saw, drill press, table saw, etc., it may be desirable to clamp the workpiece to the base of the power tool or against a fence attached to the power tool. However, many individuals do not use available prior art clamps as they can be difficult to adjust when clamping or releasing a workpiece and/or difficult to install on the power tool. For example, some prior art clamps, such as the one illustrated in U.S. Pat. No. 5,582,089, requires a user to repeatedly rotate a threaded rod to clamp or release the workpiece.
It is therefore an object of this invention to provide a clamp that is easy to adjust when clamping or releasing a workpiece and that is easy to install on the power tool.
SUMMARY OF THE INVENTION
In accordance with the present invention, an improved clamping apparatus is employed. The clamping apparatus includes a clamp body having a first and a second end, an attachment member having a first and second end, the first end of the attachment member connected to the first end of the clamp body, a clamping member having a first end and a second end, the clamping member slidably connected to the second end of the clamp body, a locking mechanism for locking the clamping member, and a spring biasing the locking mechanism towards a locking position.
Additional features and benefits of the present invention are described, and will be apparent from, the accompanying drawings and the detailed description below.
