ABSTRACT:
Arrangements are disclosed for a lightweight engine frame wherein weight reduction and manufacturing simplicity are obtained primarily through the use of skeletal box frames fabricated from extruded material joined at their ends forming a unique double lap joint assembly without the need for additional components. The disclosure describes the inventions advantageous corner construction which permits simple assembly with a minimum of tools. Also the described construction may be combined with a soundproofed exterior shell. Shown is an engine of the axial type, but similar constructions may be employed for other engine types, as well as transmission cases and where precise frame structures are required and the use of this invention may be an economic alternative.
