Abstract
A table saw fence includes a clamping member at both the front and rear of the fence to provide substantial clamping power and accuracy. The fence includes an interior cavity housing a linkage mechanism that engages the front and rear clamps through the actuation of a single handle. Furthermore, the fence includes an opening leading to the interior cavity, thereby permitting the blade, riving knife, blade guard, and any other blade accessories to extend within the interior cavity when the fence is used in a blade cover configuration.
Claims17
A rip fence for a table saw comprising:
- a casing including an upper wall, a lower wall, a first sidewall, and a second sidewall that collectively define an interior cavity configured to receive a portion of a circular saw blade extending through a table when the casing is placed on the table, the lower wall including an opening through which the blade extends when the blade is received in the interior cavity,
- a first lock member provided on a first end of the casing;
- a second lock member provided on a second end of the casing;
- and
- a channel structure formed in the first sidewall of the casing longitudinally extending between the first end and the second end of the casing,
- a linkage residing in the channel structure and operably connecting the first lock member and the second lock member, the linkage configured to move the second lock member to a locked position when the first lock member is moved to a locked position, and to move the second lock member to an unlocked position when the first lock member is moved to an unlocked position;
- wherein the channel structure is spaced apart from the upper wall and the second sidewall.

An apparatus for cutting comprising:
- a table comprising a planar surface with an opening;
- a blade projecting through the opening in the table;
- a first fence guide secured to one side of the table;
- a second fence guide secured to an opposite side of the table;
- and
- a fence releasably secured to the table, the fence including,
- a casing including an upper wall, a lower wall, a first sidewall, and a second sidewall that collectively define an interior cavity configured to receive a portion of the blade, the lower wall including an opening into the interior cavity through which the blade is configured to extend when received in the interior cavity,
- a first clamp positioned on a first end of the casing, the first clamp configured to selectively clamp onto or release from the first fence guide,
- a second clamp positioned on a second end of the casing, the second clamp configured to selectively clamp onto or release from the second fence guide,
- a channel structure formed in the first sidewall of the casing longitudinally extending between the first end and the second end of the casing,
- a linkage residing in the channel structure and extending between the first clamp and the second clamp, the linkage configured to engage the second clamp such that the second clamp is clamped to the second fence guide when the first clamp is clamped to the first fence guide and such that the second clamp is released from the second fence guide when the first clamp is released from the first fence guide,
- wherein the channel structure is spaced apart from the upper wall and the second sidewall of the casing.
