ABSTRACT:
A cutting machine to form a tenon at each end of a piece of timber, which tenon has opposite faces which are inclined both longitudinally and transversely relative to the piece of timber and forming hereinafter called skew tenon faces. This tenon cutting machine is of simple construction and uses a single and simple cutting head to produce both skew tenon faces at each end of a piece of timber. This machine includes a bench to hold a piece of timber with one end thereof overhanging the bench, an arm pivotable operatively transversely to the piece of timber at this one end of the latter, a carriage slidable along the pivotable arm, a rotatable cutting head bodily displaceable with the carriage transversely of the piece of timber in any of two oblique directions relative to opposite faces of the piece of timber, a motor rotating the cutting head, one hydraulic cylinder selectively pivoting the arm for operative cutting displacement of the cutting head and carriage consecutively in the two oblique directions, in response to sliding of the carriage along the pivotable arm under the action of a second hydraulic cylinder.
