Abstract
A sawmill includes a four-stroke internal combustion engine having an output shaft for driving a sawblade. The output shaft has a longitudinal axis. The engine is mounted on the sawmill for rotation between a first operative position with the longitudinal axis of the output shaft extending at a first angle, and a second operative position with the longitudinal axis of the output shaft extending at a second angle transversely to the first angle. The engine has fuel injection to facilitate operation in the first and second operative positions and a lubrication system incorporating a wet sump. An oil pick up for the lubrication system is configured to pick up oil from the wet sump at both the first and second operative positions.
Claims28
A sawmill including:
- an engine or motor having an output shaft for driving a sawblade, the output shaft having a longitudinal axis;
- a support apparatus for supporting the engine or motor, the support apparatus including a support framework, the engine or motor configured to selectively pivot relative to a portion of the support framework between a first operative position with the longitudinal axis extending at a first angle, and a second operative position with the longitudinal axis extending at a second angle different to the first angle,
- the support apparatus further including a pivot body pivotably mounting the engine or motor to said portion of the support framework, the pivot body including:
- pivot portions for pivotable mounting of the pivot body about a pivot axis to said portion of the support framework;
- a mounting portion to which the engine/motor is secured, the mounting portion surrounding the output shaft;
- and
- a housing portion to accommodate the output shaft exited from the engine/motor.
The sawmill as claimed in claim, 4 wherein the first and second operative positions are the only selectable operative positions.
A pivot body to pivotably mount an engine or motor to a portion of a support framework, the pivot body including:
- pivot portions for pivotable mounting of the pivot body about a pivot axis to said portion of the support framework;
- a housing portion having a mouth to receive an output shaft of the engine/motor;
- and
- a peripheral mounting portion at the mouth of the housing portion for mounting of the engine/motor.
