Title:
VERTICAL SHAFT INTERNAL COMBUSTION ENGINE WITH OVERHEAD POWER TAKE-OFF
Document Type and Number:
WIPO Patent Application WO2003036060
Kind Code:
A3
Abstract:
An internal combustion engine includes a crankcase and a crankshaft mounted vertically in the crankcase. The crankshaft has an end that extends outwardly from the bottom of the crankcase for attachment to a primary implement, such as a lawnmower blade, that is to be driven by the engine. Another end of the crankshaft extends outwardly from the top of the crankcase and has a coupling to engage an accessory device. The accessory device may be permanently or removably attached to the engine. Preferably, a cover extends over the top of the crankcase and has an exterior surface from which a well extends toward the crankcase. The coupling projects into the well, but does not extend outwardly beyond the exterior surface of the cover so that the well thereby shields the rotating coupling from inadvertent contact by the user of the equipment on which the engine is mounted. A cap also may close the well when an accessory device is not connected to the coupling to further safeguard against inadvertent contact.
