Compound miter saw

In a compound miter saw, a supporting frame, a turntable selectively rotatably mounted on said supporting frame, a power driven saw blade pivotally mounted on said turntable along a predetermined path relative to said turntable, and said turntable having saw blade slot means for receiving the saw blade therein, the improvement comprising:

• a work supporting fence having a bottom surface mounted upon said supporting frame and including a pair of work engaging surfaces longitudinally aligned across the saw blade slot means, said work supporting fence having first angularly offset surfaces on each side of said saw blade slot means which are aligned in generally parallel relationship with second angularly offset surfaces provided in said supporting frame, and clamping means for clamping the first angularly offset surfaces of said work supporting fence relative to the second angularly offset surfaces of said supporting frame.

In a compound miter saw pivotally mounted on a supporting frame between an operational position, when lowered, and a rest position, when raised, and having a motor driven saw blade rotatably mounted on a shaft, a housing partially encasing the saw blade, and a swinging blade guard arranged to cover an exposed area of the saw blade when in its rest position, the improvement comprising:

• said swinging blade guard having a pivot center on said housing which is eccentrically offset upwards from the saw blade shaft and backwards toward the pivotal mounting of said compound miter saw, the eccentrically offset pivot center of said swinging blade guard being located on a detachable mounting plate that also pivots on said housing on a second eccentrically offset pivot center when detached at one end from said housing, to facilitate access to the saw blade shaft without substracting from workpiece capacity when the compound miter saw is used in miter or bevel operations.

In a compound miter saw, a supporting frame, a turntable selectively rotatably mounted on said supporting frame for selective miter adjustment, a saw blade being pivotally mounted on said turntable for movement between an operational position, when lowered, and an at rest position, when raised, said saw blade also being pivotally mounted on said turntable for bevel pivot adjustment in a direction generally transverse to the pivotal movement of said saw blade between operational and at rest positions, the improvement comprising:

• first and second closed cylinders extending transversely relative to one another and having transversely extending axes, said first and second transversely extending closed cylinders being positioned between said supporting frame and said saw blade, the first closed cylinder including means for the pivot movement of said saw blade between operational and at rest positions, and said second closed cylinder including means for the bevel pivot adjustment of said saw blade relative to said turntable.

A compound miter saw comprising:

• a supporting frame, a turntable selectively rotatably mounted on said supporting frame and including a handle and index spring assembly for selectively rotatably positioning said turntable relative to said supporting frame, a power driven saw blade pivotally mounted on said turntable along a predetermined path relative to said turntable, said turntable having saw blade slot means for receiving the saw therein, a work supporting fence mounted on said supporting frame and including a pair of work engaging surfaces longitudinally aligned across the saw blade slot means, said work supporting fence including a depending arm extending through said saw blade slot means and being received within an elongated opening in said index spring, and said work supporting fence having first angularly offset surfaces on each side of said saw blade slot means which are aligned in generally parallel relationship with second angularly offset surfaces provided in said supporting frame, and clamping means for clamping the first angularly offset surfaces of said work supporting fence relative to the second angularly offset surfaces of said supporting frame.

A compound miter saw, said saw being pivotally mounted on a supporting frame between an operational position, when lowered, and a rest position, when raised, said pivotally mounted saw including a motor driven saw blade rotatably mounted on a shaft, a housing partially encasing the saw blade, a swinging blade guard arranged to cover an exposed area of the saw blade when in its rest position, said swinging blade guard having a pivot center on said housing which is eccentrically offset upwards from the saw blade shaft and backwards toward the pivotal mounting of said compound miter saw, the eccentrically offset pivot center of said swinging blade guard being located on a detachable mounting plate that also pivots on said housing on a second eccentrically offset pivot center when detached at one end from said housing, and said swinging blade guard including an actuator arm which is eccentrically offset from the pivot center of the swinging blade guard, whereby to facilitate access to the saw blade shaft.

A compound miter saw comprising:

• a supporting frame, a turntable selectively rotatably mounted on said supporting frame for selective miter adjustment, a saw blade being pivotally mounted on said turntable for movement between an operational position when lowered, and an at rest position, when raised, said saw blade also being pivotally mounted on said turntable for bevel pivot adjustment in a direction generally transverse to the pivotal movement of said saw blade between operational and at rest positions, first and second closed cylinders extending transversely relative to one another and having transversely extending axes, said first and second transversely extending closed cylinders being positioned between said supporting frame and said saw blade, the first closed cylinder including fixed and movable cylinder sections for pivotal movement of said saw blade between operational and at rest positions, and said second closed cylinder including fixed and movable cylinder sections for bevel pivot adjustment of said saw blade relative to said turntable, and said first and second transversely extending closed cylinder sections being integrally joined and fixed to one another across one of the fixed and movable cylinder sections between said first and second transversely extending closed cylinders.
