Abstract
Abstract A self-propelled harvester thresher having a grain tank, an engine compartment mounted on top the separator in front of the grain tank, an operator''s platform mounted adjacent to one side of the engine compartment, an engine mounted in the engine compartment, a first driven rotary screen mounted on the side of the engine compartment adjacent to the operator''s platform, a radiator mounted inside the engine compartment, and a first fan mounted adjacent to the radiator for pulling air through the screen and the radiator and forcing the air to move across the rear portion of the engine compartment and out through a grill in the side of the engine compartment away from the operator''s platform. A second fan is mounted on the wall of the engine compartment adjacent to the operator''s platform for pulling air through a driven rotary screen and forcing the air to move through the forward portion of the engine compartment. Oil coolers for the hydraulic systems and condensers for air conditioners can be placed adjacent to the fans inside the engine compartment.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
317 words
In a self-propelled combine having a frame with a table and a separator mounted on the frame for performing conventional crop harvesting and treating operations, and traction drive wheels and steerable wheels to support the frame, the combination including: a grain tank for temporary storage of grain mounted on the frame, an operator''s platform mounted on the frame, an enclosed engine compartment with a front wall, two sidewalls and a top wall mounted on the frame above the traction drive wheels, on top of the separator, in front of the grain tank and adjacent to one side of the operator''s platform, a liquid cooled engine mounted in the engine compartment, an output shaft connected to the engine for propelling the combine and for driving the table and separator, at least two air intake openings on the side of the engine compartment adjacent to the operator''s platform, at least two fans for moving air through the air intake openings, into the engine compartment, a radiator mounted in the rear portion of the engine compartment between a first one of the fans and a first one of the air intake openings, an enclosure betWeen the radiator and said first one of the air intake openings, a heat exchanger secured in the enclosure between the radiator and said first one of the air intake openings, at least two rotary screens driven by the engine to filter the air which passes through the air intake openings on the side of the engine compartment adjacent to the operator''s platform, a second enclosure mounted in the forward portion of the engine compartment between a second one of the air intake openings and a second one of the fans, a heat exchanger secured in the second enclosure, and at least one opening on the side of the engine compartment away from the operator''s platform for the passage of air out of the engine compartment.

Claim 3
Dependent Claim
245 words
A self-propelled combine including a frame, a separator mounted on the frame, a grain tank mounted on the frame, traction drive wheels to propel the combine and support the forward portion of the frame, steerable wheels to steer the combine and support the rear portion of the frame, an engine compartment mounted on the frame above the separator in front of the grain tank and above the traction drive wheels, a liquid cooled engine mounted in the engine compartment with the axis of its crankshaft perpendicular to the direction of travel of the combine, an operator''s platform mounted adjacent to one side of the engine compartment above the traction drive wheels and forward of the rear wall of the engine compartment, an air intake in the side of the engine compartment adjacent to the operator''s platform, a rotary screen to filter the air entering the engine compartment through said air intake mounted on the frame to rear of the operator''s platform, a radiator mounted in the rear portion of the engine compartment adjacent to the air intake, a fan mounted in the engine compartment adjacent to the radiator for pulling air through the rotary screen and the radiator and for forcing the air into the engine compartment to pressurize the engine compartment, and at least one opening on the side of the engine compartment away from the operator''s platform for the passage of air out of the engine compartment and away from the operator''s platform.
Claim 4
Dependent Claim
245 words
A self-propelled combine including a frame, a separator mounted on the frame, a grain tank mounted on the frame, traction drive wheels to propel the combine and support the forward portion of the frame, steerable wheels to steer the combine and support the rear portion of the frame, an engine compartment mounted on the frame above the separator in front of the grain tank and above the traction drive wheels, a liquid cooled engine mounted in the engine compartment with the axis of its crankshaft perpendicular to the direction of travel of the combine, an operator''s platform mounted adjacent to one side of the engine compartment above the traction drive wheels and forward of the rear wall of the engine compartment, an air intake in the side of the engine compartment adjacent to the operator''s platform, a rotary screen to filter the air entering the engine compartment through said air intake mounted on the frame to rear of the operator''s platform, a radiator mounted in the rear portion of the engine compartment adjacent to the air intake, a fan mounted in the engine compartment adjacent to the radiator for pulling air through the rotary screen and the radiator and for forcing the air into the engine compartment to pressurize the engine compartment, and at least one opening on the side of the engine compartment away from the operator''s platform for the passage of air out of the engine compartment and away from the operator''s platform.
Claim 5
Dependent Claim
51 words
The combine of claim 2 including a second air intake opening in the side of the engine compartment adjacent to the operator''s platform, a fan to pull air through the second air intake and a rotary screen to filter the air entering the engine compartment through the second air intake opening.
Claim 6
Dependent Claim
14 words
