A device is disclosed for assembling frames and moulding frames, comprising a monolithic assembly piece (31) forming a double tenon and having the form of two identical circular truncated cones of a height substantially equal to the thickness of the workpieces (32, 33) to be assembled. Said assembly piece is fitted into blind bores (34, 35) of corresponding shape having on the edge junction surfaces of the workpieces to be assembled. It is intended to assembling, with or without bonding, joinery pieces of wood or other materials, such as mitered moulding frames. The mitering machine for implementing the assembly device (31) comprises a sealed casing (1) equipped with two circular saw blades (4, 5) perpendicular to each other and driven with a single electric motor. The casing is mobile vertically with respect to a working surface (3) equipped with fixing means (15, 16) for the workpiece to be cut. Two conical milling tools (28) situated under the working surface provide simultaneously the bores (34, 35) of the workpieces to be assembled.
摘要:
A fastening device of preferably spring steel for securing abutting members having a rectangular shaped body portion with leg portions extending at right angle at the leading edge and at an acute angle at the trailing edge. The leading edges of the body and leg portions having V-shaped notches with sharpened edge portions whereby upon forcing the fastening device into the abutting members, the body and leg portions cut a slot along which the fastener slides with the leg portions yieldingly forcing the abutting members in a direction toward each other.
