ABSTRACT:
A cutting tool guide device fits within a window frame in a vertically mounted position. The device guides a cutting tool, such as a router, along the X,Y, and Z coordinates. Simultaneous movement along the X and Y coordinates parallel to the window is possible by means of vertical and horizontal controls which allows any angle or curves to be followed. Measured adjustment along the Z coordinate, perpendicular to the window, is provided by a screw threaded router tool casing mounted in a collar with external measured detentes contacted by a spring loaded ball. Rotary movement of the router is restrained by a slot in the router receiving a-pin. Great precision is obtained in removing glazing from a window sash and in cutting into the rabbit joint of the sash. The cutting allows double pane glass to be inserted into the sash. The cutting tool guide device is adjustable to fit into various sized window frames. Resilient material at the points where the guide device contacts the window frame in a tensioned relationship prevents harm to the window frame. The guide device may be mounted on a separate frame to hold a window which has been removed from a building.
