Abstract: An apparatus for mitre cutting an elongated moulding to produced a mitred end, and for cutting a groove in the end comprises a frame having longitudinal and lateral extent, and a laterally elongated table on the frame to receive and support a first portion of a moulding extending longitudinally; a first clamp on the frame for clamping the moulding to a first portion of the table; a first carriage supported by the frame to travel laterally back and forth, relative to the table; a first rotary disc cutter and a drive therefor supported on the carriage for cutting the clamped moulding laterally therethrough to produce the mitred end, as the carriage travels laterally; and a first router and a drive therefore supported by the carriage for laterally penetrating the mitred end of the moulding as the carriage travels laterally, for cutting the groove in the mitred end.

Abstract: Apparatus for cutting grooves in moulding members adapted to have their ends joined in L-shaped assembly by an L-shaped bracket, the apparatus comprising:(a) a first base, and a first guide surface on the base to engage the back side of the moulding thereby to position the moulding directionally laterally, and to extend directionally longitudinally,(b) a first stop to engage and position the mitred end of the moulding, thereby to position the moulding longitudinally,(c) clamp means movable to engage the positioned moulding and retain the moulding on the base,(d) a first router and a rotary drive therefor, the router projecting into lapping relation with said mitred end of the moulding,(e) means to displace the first rotating router relative to the base to directionally sidewardly engage and penetrate the mitred end of the moulding, thereby to produce said groove, the router thereafter being sidewardly removable from said groove,(f) and means to adjustably position the base, laterally, thereby to position the

Abstract: Apparatus for cutting an insert groove in a longitudinally elongated moulding having a backside and mitred end includes:(a) a first base, and a first guide surface on the base to engage the back side of the moulding thereby to position the moulding directionally laterally, and to extend directionally logitudinally,(b) a first stop to engage and position the mitred end of the moulding, thereby to position the moulding longitudinally,(c) clamp structure movable to engage the positioned moulding and retain the moulding on the base,(d) a first router and a rotary drive therefor, the router projecting into lapping relation with the mitred end of the moulding,(e) and guide structure to guide bodily displacement of the first rotating router relative to the base to directionally engage and penetrate the mitred end of the moulding, thereby to produce the groove, the router thereafter being sidewardly removable from the groove.
