Abstract
A machine for cutting one or two slots in the sides of a log intended for use as a roofing rafter, the machine including a pair of dado saws, means for moving the saws up and down past the sides of a log, and supports for the saws which are adjustable to coordinate the angle of the cuts with the angle of a previously made notch.
Claims6
A machine for side slotting a roofing rafter comprising means for supporting a rafter in a horizontal position, at least one rotary saw rotatable on an axis lying in a vertical plane parallel to the vertical plane through the center line of the rafter and spaced laterally therefrom, a motor operatively connected to the saw, a support for the saw and motor, the saw and motor support being pivotally mounted for movement around an axis perpendicular to said vertical planes and being independently laterally displaceable, means for adjusting the angular position of said saw and motor support, means for laterally displacing said saw and motor support, and means for moving the saw upward and downward along a rafter side cutting path.
A machine for side slotting a roofing rafter comprising means for supporting a rafter in a horizontal position, a pair of rotary saws each rotatable on an axis lying in a vertical plane parallel to and on opposite sides of the vertical plane through the center line of the rafter, a pair of motors each connected to a respective saw, supports for the saws and motors, each saw and motor support being pivotally mounted for movement around an axis perpendicular to said vertical planes, means for adjusting simultaneously the angular positions of both said saw and motor supports, and separate means for moving the saws into rafter cutting position.
