Abstract
A power tool assembly includes a workpiece support surface, a throat opening defined in the workpiece support surface, an arbor shaft configured to support a shaping device, the arbor shaft positioned beneath the workpiece support surface and accessible through the throat opening, and a camming device rotatably mounted at a location adjacent to the throat opening, the camming device including a first camming surface portion configured to cam against a second camming surface potion of a throat plate inserted into the throat opening, thereby locking the throat plate within the throat opening.
Claims16
A power tool assembly comprising:
- a workpiece support surface;
- a throat opening defined in the workpiece support surface;
- an arbor shaft configured to support a shaping device, the arbor shaft positioned beneath the workpiece support surface and accessible through the throat opening;
- and
- a camming device rotatably mounted at a location adjacent to the throat opening, the camming device including a first camming surface portion configured to cam against a second camming surface potion of a throat plate inserted into the throat opening, thereby locking the throat plate within the throat opening.
The power tool assembly of claim 8, wherein:
- the camming device is located adjacent a first end portion of the throat plate opening;
- the workpiece support surface includes at least one tab receiving structure adjacent a second end portion of the throat plate opening, the second end portion opposite the first end portion;
- and
- the throat plate includes at least one tab configured to be inserted within the at least one tab receiving structure when the throat plate is inserted into the throat opening.
A method of installing a shaping device in a power tool assembly comprising:
- rotating a camming device rotatably mounted at a location adjacent to a throat opening in a workpiece support surface of the power tool assembly in a first direction to unlock a throat plate;
- removing the throat plate to expose an arbor shaft with the camming device still mounted;
- mounting a shaping device on the exposed arbor shaft;
- inserting the throat plate in the throat plate opening after the shaping device is mounted on the arbor shaft;
- and
- rotating the camming device in a second direction opposite the first direction to cam a first camming surface portion of the camming device against a second camming surface potion of the inserted throat plate, thereby locking the throat plate within the throat opening.
