Abstract
A guide assembly in one embodiment includes at least one guide rigidly supported by a table saw, a bearing assembly including a first, a second, and a third bearing engaged with the at least one guide, and a fence base assembly supported by the bearing assembly, wherein the first and the second bearings are biased in a first direction with respect to the at least one guide and the third bearing is biased in a second direction with respect to the at least one guide, the second direction at least partially opposite to the first direction.
Claims13
A table saw guide assembly, comprising:
- a rail including a base portion and a guide portion and rigidly supported by a table saw, the guide portion including a guide cavity defining two guides, the two guides arranged opposing one another and rigidly supported by the table saw;
- a bearing assembly including a first, a second, and a third bearing engaged with the guide portion;
- and
- a fence base assembly supported by the bearing assembly,
- wherein the first and the second bearings are biased in a first direction with respect to the guide portion and the third bearing is biased in a second direction with respect to the guide portion, the second direction at least partially opposite to the first direction.
A guide assembly comprising:
- a clamp bar fixedly positioned with respect to a table saw and extending along one side of the table saw;
- a first spring plate releasably engageable with the clamp bar;
- a second spring plate releasably engageable with the clamp bar;
- and
- a cam lock configured to selectively bias the first spring plate toward a first side of the clamp bar and to selectively bias the second spring plate toward a second side of the clamp bar,
- wherein the cam lock is hingedly connected to a cam lock actuator,
- wherein the cam lock actuator is pivotably connected to a fence base portion,
- wherein the first spring plate is pivotably connected to the fence base portion, and
- wherein the second spring plate is pivotably connected to the fence base portion.
A guide assembly comprising:
- a clamp bar fixedly positioned with respect to a table saw;
- a first spring plate releasably engageable with the clamp bar;
- a second spring plate releasably engageable with the clamp bar;
- a cam lock configured to selectively bias the first spring plate toward a first side of the clamp bar and to selectively bias the second spring plate toward a second side of the clamp bar;
- a rail defining the clamp bar and fixedly attached to the table saw;
- a pair of opposing guides rigidly supported by the rail;
- and
- a bearing assembly including a first, a second, and a third bearing engaged with the pair of opposing guides, wherein the first and the second bearing are biased toward a first of the pair of opposing guides and the third bearing is biased toward a second of the pair of opposing guides.
