-20- Abstract Horizontal motorized drive rods in an upright rectangular frame control the movement of vertical guide rods in the X direction of the frame. Motorized guide rods move a router on a movable mount along the Y direction. A plungeable router, spring-mounted on the guide rods, is moved adjustably into the plane in the Z direction. The router removes glazing from a window sash and cuts deeper into the rabbit joint of the sash to allow double pane glass to be inserted into the sash. A rotary saw, with blade depth adjustment is swivel mounted to another vertical guide for cutting a slot in both vertical and horizontal rabbit joints to receive glazing beads. Pins rigidly mounted in front of and behind the cutting edges of the rotary saw blade act as guides and stops for the saw. Horizontal threaded rods with opposing right and left threads on either side of the center of the horizontal rod forms a centering device. A pair of depressable spring-loaded stops are equally spaced from the center of the rod, and a crank moves the stops reversibly. Sashes are centrally mounted on the frame using a sash centering device. A rotary saw slidably mounted on a vertical guide is positioned by a guide centering device. Equal amounts are out off each side of a sash using a rotary saw. A spring-loaded pulley or counterweight is strung from the top of the vertical bar and connoted to the cutting tools to help support them. The frame is adjustable to be mounted on various sized window frames or to allow sashes of various sizes and shapes to be mounted on the frame between clamp members on the frame.
