ABSTRACT:
A chain saw having a housing in the form of a plastic shell of structural foam fully open on one of its lateral sides to expose a central chamber. The chain saw includes an integral motion assembly formed of an engine, a blade mounting bracket, forwardly projecting blade and driven cutter chain. A mounting plate is secured to the underside of the engine, the plate being formed of a thin plate of metal having substantially parallel front and rear edges received in front and rear grooves within the shell, the central chamber being sized to receive the engine so that the engine and mounting plate may be slid into seated but floating position in the chamber in the manner of a drawer. Resilient connectors interposed between the engine mounting plate and the shell and interposed between the blade mounting bracket and the shell hold the motion assembly in seated position. A closure plate also formed of structural foam encloses the open lateral side of the shell while providing clearance for the forwardly projecting blade and the cutter chain mounted therein.
