Disclosed is an exhaust silencer suitable for use with portable combustion engines, and particularly for use with chain saw engines, comprising a chamber having an inlet and outlet for receiving the engine exhaust; means disposed about the chamber outlet for reducing the kinetic energy of the exhaust flowing therethrough; and an air duct means mounted exteriorly of the chamber below the chamber outlet for cooling the chamber, the kinetic energy reducing means, and the exhaust gas by contact with a stream of ambient air flowing therethrough.

Silencer, especially for portable motor chain saws

A spring action guide bar stop for portable power chain saw is located adjacent the saw housing near where the chain returns to the housing to absorb and dampen vibration during operation of the saw. The spring stop is preferably a leaf spring coiled into a loop so that the side of the loop contacts the object being cut with friction dampening being obtained by providing frictional contact between the ends of the spring loop.
