A chain saw having a resilient deflectable rear handle. The rear handle is connected to a housing of the chain saw at a first end and has a second end that is cantilevered. A portion of the housing is suitably sized, shaped and positioned relative to the rear handle second end to form a deflection overload constraint to prevent the rear handle from deflecting too much. The cantilevered configuration of the rear handle and its deflectability allow vibrations generated during operation of the chain saw to be reduced at an operator's grasping location on the rear handle.

A flywheel magnet rotor assembly. The assembly comprises a core, a magnet, two pole shoes and a molded resin disk. The core is comprised of metallic nonferromagnetic material forming a general can shape with apertures through a first wall. The magnet is sandwiched between the pole shoes inside the can shape and portions of the pole shoes extend out the apertures. The molded resin disk substantially surrounds the core.

A carburetor and chain oiling assembly and method of manufacturing the same for use in a chain saw. The assembly generally comprises a carburetor section, an oil pump section and a cover connecting the two sections. The cover can connect the oil pump section to the carburetor section forming a cover for a carburetor fuel diaphragm and a working chamber with an oil pump diaphragm. The cover has a gas conduit between the carburetor housing and the working chamber such that gas pulses from an engine crankcase can be supplied to the working chamber to operably move the oil pump diaphragm to provide a continuous and automatic metered flow of oil to a saw chain.

Carburetor and oil pump assembly and method of making the same

The invention is directed to a self regulating rotor for a centrifugal clutch. The rotor is designed to reduce the clearance between the rotor and the the drum by being stressed above its elastic limit as speeds above the normal engagement speed whereby any enlargement of the rotor diameter that occurs above the eleastic limit results in a permanent set.

Self adjusting rotor for a centrifugal clutch

The invention is directed to a rotor for a centrifugal clutch of the type where the rotor resides inside a drum and engages the drum above a predetermined speed. The rotor comprises a plurality of randomly oriented similar rotor elements each capable of expanding ourwardly independently of one another to engage the drum. The rotor elements are preferably stamped from sheet metal.
