ABSTRACT:
A new and improved miter apparatus includes a base plate assembly which includes a front end, two sides, and a rear end. The base plate assembly includes a slot at the front end midway between the two side members for receiving a saw blade. A track assembly is located between the rear end and the slot on the base plate assembly. A carriage assembly is supported by the track assembly. The carriage assembly is capable of being moved back and forth along the track assembly. The carriage assembly includes a first pivot assembly and a second pivot assembly supported by the base plate assembly at a position between the track assembly and the slot on the base plate assembly. A pair of miter arms are pivotally connected to the second pivot assembly. The miter arms include respective third pivot assemblies supported by the miter arms. A pair of control arms are connected between the first pivot assembly and the respective third pivot assemblies, such that when the carriage assembly is moved along the track assembly toward the slot, the miter arms move such that respective miter angles between the slot and the respective miter arms decrease. Conversely, when the carriage assembly is moved along the track assembly away from the slot, the respective miter angles between the slot and the respective miter arms increase. A tongue assembly is attached to a bottom side of the base plate assembly and rides in a complementary slot in a table.
