Abstract
Abstract An anti-fouling air intake stack for use on an agricultural combine which is equipped with a swingable rotary screen air filter basket. The air intake stack provides an elevated air intake which is of greater elevation above ground level than the normal air intake and which draws cooling air for the engine, hydraulic and air conditioning components of the combine from a height which is relatively debris-free while allowing unimpaired access to the combine engine compartment.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
An anti-fouling, air intake stack for use on a combine having an engine, a housing enclosing the engine including a vertical portion having an aperture through which air travels for cooling the engine, and a rotary screen air-filtering basket mounted on the vertical portion and extending outwardly around the periphery of the aperture, said stack comprising: a vertical, single-chambered box having an open top, and an open bottom, said box including a member positioned and arranged to be selectively movable between a first position closing said bottom and a second position in which the bottom is at least partially open, and vertical sides attached to and extending from the bottom, including one side with an opening disposed adjacent said bottom and sized to allow passage of the basket freely therethrough, said one side being fixedly mountable on the vertical portion so as to allow the basket to extend through the side opening, said box being sized to receive internally, entirely and unobstructedly the basket when said one side is mounted on the vertical portion.
Claim 2
Dependent Claim
174 words
An anti-fouling, air intake stack for use on a combine having an engine, a housing enclosing the engine including a vertical portion having an aperture through which air travels for cooling the engine, and a rotary screen air-filtering basket mounted on the vertical portion and extending outwardly around the periphery of the aperture, said stack comprising: a vertical, single-chambered box having an open top, and an open bottom, said box including a member positioned and arranged to be selectively movable between a first position closing said bottom and a second position in which the bottom is at least partially open, and vertical sides attached to and extending from the bottom, including one side with an opening disposed adjacent said bottom and sized to allow passage of the basket freely therethrough, said one side being fixedly mountable on the vertical portion so as to allow the basket to extend through the side opening, said box being sized to receive internally, entirely and unobstructedly the basket when said one side is mounted on the vertical portion.
Claim 3
Dependent Claim
23 words
The stack of claim 1, wherein said member is positioned and arranged to be slidably movable between said first and said second positions.
Claim 4
Dependent Claim
175 words
A single-chambered, anti-fouling air intake stack for use on a combine having an engine, a housing enclosing the engine including a vertical portion having an aperture through which air travels for cooling the engine, and a rotary screen air-filtering basket mounted on the vertical portion and extending outwardly around the aperture periphery, said stack comprising an open bottom and a member positioned and arranged to be selectively slidable between a first position closing the bottom and a second position in which the bottom is at least partially open, and vertical wall means joined to said bottom and having an opening sized to allow passage of such a basket therethrough, mountable on the vertical portion so as to allow the basket to extend through said opening, said walls forming at their top an air inlet disposed substantially vertically so as to be above such basket when operatively received within said intake, said walls and bottom being constructed to receive internally, entirely and unobstructedly the basket when said wall means is operatively mounted on the vertical portion.
Claim 5
