Abstract
A workstation having an assembly that includes a support for holding a jamb positioned with the face thereof at a site for mortising a hinge pocket in the face, a support for receiving and holding a door with its hinge side edge at the site adjacent to and parallel with the jamb for mortising operations at that edge and a cutting tool carried by the assembly operating to form hinge mortises in an edge of the door and the jamb face at the site. The support for the door is operable to pivot the door about the hinge side edge of the door from a first angle for forming hinge mortises in the hinge edge of a door having a bevel and a second angle for forming hinge mortises in the hinge edge of a door having no bevel.
Claims10
A workstation suitable for processing a jamb having a face along a longitudinal side of the jamb and a door having a longitudinal hinge receiving side edge and an opposed latch receiving side edge, the hinge receiving side edge being for receiving at least one butt hinge having a pair of hinge leaves, one of the leaves to be applied to the door edge and the other leaf to an adjacent jamb face and the workstation being suitable for selectively processing a door having either a square or beveled hinge receiving side edge which comprises:
- a. structure for supporting a door and a jamb for processing and for supporting equipment for processing the door edge and jamb face;
- b. at least one butt router supported on the structure, the router having a rotatable cutter that routs about a rotational axis and is capable of routing in a forward direction of the cutter axis of rotation and transversely of the cutter axis of rotation, the router being positioned to rout in the forward direction of the cutter rotational axis from a preselected routing contact position and transversely to the forward direction, the router being provided with means for moving the router cutter on a routing path transverse to the router cutter rotational axis for forming mortises along the path;
- c. means operably positioned on the structure relative to the butt router for holding the jamb with the jamb face at the routing contact position confronting, coplanar with and extending along the router transverse routing path;
- and
- d. means operably positioned on the structure relative to the butt router for holding a door with a hinge receiving side edge adjacent to the jamb and at the routing contact position confronting, coplanar with and extending along the router transverse routing path, the door holding means being adapted to hold the door at a first angle about the hinge side edge, for forming hinge mortises in the hinge edge of a door having a bevel, and at which the beveled edge is coplanar with the router transverse routing path, and, alternatively, at a second angle about the hinge side edge, for forming hinge mortises in the hinge edge of a door having a square edge, and at which the square edge is coplanar with the router transverse routing path.

- c. an automatic door hinger on the structure in a position operable to apply, at the transverse routing path at the routing contact position, a butt hinge between the jamb face and the door edge, with one hinge leaf at a hinge pocket in the door edge and the other leaf at a hinge pocket in the adjacent jamb face;
- d. means operably positioned on the structure relative to the butt router for holding the jamb with the jamb face at the routing contact position confronting, coplanar with and extending along the router transverse routing path;
- and
- e. means operably positioned on the structure relative to the butt router for holding a door with a hinge receiving side edge adjacent to the jamb and at the routing contact position confronting, coplanar with and extending along the router transverse routing path, the door holding means being adapted to hold the door at a first angle about the binge side edge, for forming hinge mortises in the hinge edge of a door having a bevel, and at which the beveled edge is coplanar with the router transverse routing path, and, alternatively, at a second angle about the hinge side edge, for forming hinge mortises in the hinge edge of a door having a square edge, and at which the square edge is coplanar with the router transverse routing path, said door holding means comprising a pivotable framework, the pivotable framework having a pivot that is supported on the support structure and has a pivot axis adjacent to and extending along the transverse path of the router cutter.
