Abstract
A saw stop assembly is provided with a fence and a stop assembly. The fence may be provided with a first array of teeth. The stop assembly may also be provided with a second array of teeth. The first and second arrays of teeth are designed such to meshingly engage with one another. A clip may be provided to affix the stop to the fence.
Claims16
A saw stop assembly comprising:
- an elongated fence disposed in a first lengthwise direction comprising a plurality of first dovetail teeth disposed in repeating fashion along said first lengthwise direction, each of said first dovetail teeth further comprising at least three engagement surfaces wherein each engagement surface is disposed at an acute angle with respect to a neighboring said engagement surface in a second direction orthogonal to said first lengthwise direction;
- a first stop comprising one or more second dovetail teeth, each of said second dovetail teeth further comprising at least three stop engagement surfaces wherein each stop engagement surface is disposed at an acute angle with respect to a neighboring said stop engagement surface and which are geometrically similar to said first dovetail teeth;
- wherein each tooth of said one or more said second dovetail teeth matingly engageable with a respective one of said first dovetail teeth in only one translational direction, wherein said translational direction is both orthogonal to said first lengthwise direction and collinear with the planar surfaces of said engagement surfaces;
- and
- a second stop comprising one or more third dovetail teeth, wherein said first stop has a first dimension extending from said fence and said second stop has a second dimension extending from said fence, and wherein said first and second dimensions are unequal.

A saw stop assembly comprising:
- an elongated fence disposed in a first lengthwise direction and further comprising a first array of dovetail teeth;
- and
- a first stop comprising a second array of dovetail teeth;
- wherein each tooth of said first array of dovetail teeth comprises at least three vertical engagement surfaces wherein each engagement surface is disposed at an acute angle with respect to a neighboring said engagement surface in a second direction orthogonal to said first lengthwise direction;
- wherein said second array comprises fewer teeth than said first array;
- wherein each of said second array of dovetail teeth matingly engages with a respective one of said first array of dovetail teeth in only one translational direction, wherein said translational direction is both orthogonal to said first lengthwise direction and collinear with the planar surfaces of said engagement surfaces;
- and
- wherein said fence includes incremental markings thereon.

A saw stop assembly comprising:
- a fence having a fence rear surface, a fence front surface, and a fence top surface extending between said rear and front surfaces, said fence extending in a lengthwise direction;
- a first stop comprising a stop rear surface, a stop side surface extending substantially orthogonally from said stop rear surface, and a stop top surface extending between said stop rear surface and said stop side surface;
- a plurality of fence dovetail teeth extending laterally from said fence front surface in a direction orthogonal to said lengthwise direction;
- one or more stop dovetail teeth geometrically similar to said fence dovetail teeth and extending laterally from said stop rear surface;
- and
- a clip comprising a lateral arm and a vertical arm, said lateral arm being affixed to said stop top surface;
- wherein, when assembled, said one or more stop dovetail teeth meshingly engage some of said plurality of fence dovetail teeth only in one translational direction which is orthogonal to said lengthwise direction and orthogonal to said fence top surface and said clip lateral arm extends over said fence top surface, and said clip vertical arm is in contact with said fence rear surface.
