Abstract
Abstract A grain-harvesting apparatus with an engine enclosed in an engine compartment and a radiator for cooling the engine in a radiator compartment. A fan pulls filtered air into the engine compartment creating a positive pressure in the compartment thereby keeping dust and chaff out and cooling the compartment. Another fan pulls air into the radiator compartment through screen sections of the compartment walls, through the radiator and exhausts the hot air away from the operator''s platform.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
In a self-propelled combine having a wheeled frame with units mounted thereon for performing conventional crop harvesting and treating operations, the combination including: an operator''s platform mounted on the frame; an enclosed engine compartment mounted on the frame; a liquid cooled engine mounted in the enclosed engine compartment; first fan means to force cool air into the engine compartment to create a pressure above atmospheric pressure in the engine compartment; an air intake filter to filter the air forced into the engine compartment by said first fan means; means to transmit power from the liquid cooled engine to propel the combine and operate the units for crop harvesting and treating; an enclosed radiator compartment, mounted on the frame; a radiator for cooling the engine mounted in the enclosed radiator compartment; screened air intake for filtering the air which enters said radiator compartment; second fan means mounted inside the radiator compartment for causing air to flow through the screened air intake and through the radiator; and a plurality of ports for the escape of air from the engine compartment including at least one port located in a position relative to the radiator compartment so that the air passing through said one port tends to blow dust and chaff away from the air intake sections of the radiator compartment.

In a self-propelled combine having a wheeled frame with units mounted thereon for performing conventional crop harvesting and treating operations, the combination including: an operator''s platform mounted on the frame; an enclosed engine compartment mounted on the frame; a liquid cooled engine mounted in the enclosed engine compartment; first fan means to force cool air into the engine compartment to create a pressure above atmospheric pressure in the engine compartment; an air intake filter to filter the air forced into the engine compartment by said first fan means; means to transmit power from the liquid cooled engine to propel the combine and operate the units for crop harvesting and treating; an enclosed radiator compartment, mounted on the frame; a radiator for cooling the engine mounted in the enclosed radiator compartment; screened air intake for filtering the air which enters said radiator compartment; second fan means mounted inside the radiator compartment for causing air to flow through the screened air intake and through the radiator; and a plurality of ports for the escape of air from the engine compartment including at least one port located in a position relative to the radiator compartment so that the air passing through said one port tends to blow dust and chaff away from the air intake sections of the radiator compartment.
Claim 3
Dependent Claim
18 words
The self-propelled combine of claim 1 wherein the engine compartment air intake filter is a rotary air screen.
Claim 4
Dependent Claim
56 words
The self-propelled combine of claim 1 in which at least one of the ports for the escape of air from the engine compartment is located in a position relative to the operator''s platform so that the air that passes through said one of the ports tends to blow dust and chaff away from the operator''s platform.
