Abstract:
A scotch yoke mechanism for a reciprocating saw including a reversible rotary motor which is rotatable in both first and second directions, the second direction being opposite to the first direction, the reciprocating saw further including a saw blade operably connected to the motor such that rotational movement of the motor is converted into linear movement of the saw blade, said scotch yoke mechanism comprising:a cam operably connected to and receiving rotational force from the motor, and a stroke length toggle eccentrically connected to said cam, said stroke length toggle being adjustable between a first position and a second position, said stroke length toggle being operably connected to the saw blade; wherein rotation of said cam in said first direction causes said stroke length toggle to assume said first position which defines a first stroke length; wherein rotation of said cam in said second direction causes said stroke length toggle to assume said second position which defines a second stroke length; said first stroke length being different than said second stroke length.
