Abstract
Abstract An air flow control mechanism for use in a radiator system of the type having a radiator core constructed from a plurality of parallel core sections which are equally spaced apart and aligned in a single row with the opposing faces of adjacent core sections being open to provide air flow passageways through each core sections at right angles to the cooling air directed at the front of the radiator core. The radiator air flow control mechanism comprises gate means operatively connected in each of the spaces between adjacent core sections to pivot between a first and second position, where the gate means in the first position directs the cooling air through each of the core sections' air flow passageways in one direction and where the gate means in the second position reverses the direction of flow through each of these passageways. A drive means is provided for reciprocally moving the gate means between the first and second positions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
An improvement in a radiator system of the type having a radiator core comprising a plurality of parallel spaced core sections arranged in a row with the opposing faces of adjacent core sections being open to define an air flow passageway through each core section at a constant transverse angle to the direction that the cooling air is delivered towards said row of core sections, said improvement comprising gate means having a first position for directing the cooling air through each of said air flow pageways of said core sections in one direction and having a second position for directing the cooling air through each of said air flow passageways in the opposite direction to said one direction, and drive means for continuously reciprocating said gate means between said first and second positions.
Claim 2
Dependent Claim
133 words
An improvement in a radiator system of the type having a radiator core comprising a plurality of parallel spaced core sections arranged in a row with the opposing faces of adjacent core sections being open to define an air flow passageway through each core section at a constant transverse angle to the direction that the cooling air is delivered towards said row of core sections, said improvement comprising gate means having a first position for directing the cooling air through each of said air flow pageways of said core sections in one direction and having a second position for directing the cooling air through each of said air flow passageways in the opposite direction to said one direction, and drive means for continuously reciprocating said gate means between said first and second positions.
Claim 3
Dependent Claim
64 words
The improvement as defined in claim 1, wherein said gate means comprises a baffle plate pivotally supported between each of said adjacent core sections on an axis parrallel to said opposing faces of adjacent core sections, the width of each of said baffle plates being of sufficient length to engage the diagonally opposite corners of said opposing longitudinal faces of said adjacent core sections.
Claim 4
Dependent Claim
67 words
The improvement as defined in claim 2, wherein said drive means comprises a drive member extending across said row of core sections and in driving engagement with each of said baffle plates in a manner to reciprocally rotate said baffle plates in unison from one pair of diagonally opposite corners of said opposing faces of said adjacent core sections to the other pair of diagonally opposite corners.
Claim 5
Dependent Claim
144 words
An improvement in a radiator system of the type having a radiator core comprising a plurality of parallel equally-spaced core sections aligned in a single row with the opposing faces of adjacent core sections being open to define an air flow passageway through each core section at a constant right angle to the direction that air is delivered into the space between said adjacent core sections, said improvement comprising gate means operatively connected in each space between said adjacent core sections having a first position for directing the cooling air through each of said air flow passageways of said core sections in one direction and having a second position for directing the cooling air through each of said air flow passageways in the reverse direction to said one direction, and drive means for continuously reciprocating said gate means between said first and second positions.
Claim 6
Dependent Claim
144 words
An improvement in a radiator system of the type having a radiator core comprising a plurality of parallel equally-spaced core sections aligned in a single row with the opposing faces of adjacent core sections being open to define an air flow passageway through each core section at a constant right angle to the direction that air is delivered into the space between said adjacent core sections, said improvement comprising gate means operatively connected in each space between said adjacent core sections having a first position for directing the cooling air through each of said air flow passageways of said core sections in one direction and having a second position for directing the cooling air through each of said air flow passageways in the reverse direction to said one direction, and drive means for continuously reciprocating said gate means between said first and second positions.
Claim 7
Dependent Claim
69 words
The improvement as defined in claim 4, wherein said gate means comprises a baffle plate pivotally supported at the center of said space between each of said adjacent core sections on an axis parallel to said opposing faces of adjacent core sections, the width of each of said baffle plates being of sufficient length to engage the diagonally opposite corners of said opposing faces of said adjacent core sections.
Claim 8
Dependent Claim
70 words
The improvement as defined in claim 5, wherein said drive means includes a drive member extending across said single row of core sections and in driving engagement with each of said baffle plates in a manner to reciprocally rotate all of said baffle plates in unison from one pair of diagonally opposite corners of said opposing faces of said adjacent core sections to the other pair of diagonally opposite corners.
