Abstract
Abstract A vehicle engine radiator assembly has a radiator having first and second opposed surfaces, an inlet conduit, and an outlet conduit. A fluid coupling is connected to each conduit and is of a construction sufficient for pivotal movement of the radiator for controllably directing either the first or second surface outwardly from the vehicle. Means is provided for permitting pivotal movement of the radiator and maintaining the radiator fixed to the vehicle at a preselected position. The radiator is pivoted for changing the direction of air flow therethrough for removing dirt and other materials from the radiator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
In a vehicle engine radiator assembly having a radiator having first and second opposed cooling surfaces, an inlet conduit, an outlet conduit, and means for passing fluid from the inlet conduit to the outlet conduit while passing air from one of the cooling surfaces through the radiator and to the other cooling surface, the improvement comprising: a first fluid coupling pivotally connected to the inlet and being of a construction sufficient for passing fluid into the inlet at a first position of the radiator at which the first cooling surface is directed outwardly from the vehicle and a second position at which the second cooling surface is directed outwardly from the vehicle; a second fluid coupling pivotally connected to the outlet and being of a construction sufficient for passing fluid from the outlet at said first and second radiator positions; and first means for maintaining at least one of the fluid couplings fixed to the vehicle for movement of fluid couplings toward and from the vehicle for movement of the radiator between the first and second positions while passing fluid through the radiator from the inlet conduit to the outlet conduit.
Claim 2
Dependent Claim
191 words
In a vehicle engine radiator assembly having a radiator having first and second opposed cooling surfaces, an inlet conduit, an outlet conduit, and means for passing fluid from the inlet conduit to the outlet conduit while passing air from one of the cooling surfaces through the radiator and to the other cooling surface, the improvement comprising: a first fluid coupling pivotally connected to the inlet and being of a construction sufficient for passing fluid into the inlet at a first position of the radiator at which the first cooling surface is directed outwardly from the vehicle and a second position at which the second cooling surface is directed outwardly from the vehicle; a second fluid coupling pivotally connected to the outlet and being of a construction sufficient for passing fluid from the outlet at said first and second radiator positions; and first means for maintaining at least one of the fluid couplings fixed to the vehicle for movement of fluid couplings toward and from the vehicle for movement of the radiator between the first and second positions while passing fluid through the radiator from the inlet conduit to the outlet conduit.
Claim 3
Dependent Claim
19 words
Apparatus, as set forth in claim 1, wherein first means are associated with each first and second fluid couplings.
Claim 4
Dependent Claim
37 words
Apparatus, as set forth in claim 1, wherein said first means comprises an elongated element having an axis, a first end portion connected to the vehicle, and a second end portion connected to an associated fluid coupling.
Claim 5
Dependent Claim
45 words
Apparatus, as set forth in claim 3, wherein the first end portion of the elongated element has a slot extending along the axis; and second means extending through the slot and being connectable to the vehicle for movably connecting the first means to the vehicle.
Claim 6
Dependent Claim
96 words
Apparatus, as set forth in claim 1, wherein each fluid coupling has a chamber, a fluid passageway communicating with the chamber, and adjacent openings on opposed sides of the chamber, said adjacent openings being of sizes sufficient for receiving a respective one of the inlet and outlet conduits, and each inlet and outlet conduit has at least one opening positioned at a location sufficient for communicating with the chamber of the respective fluid coupling in the installed position therethrough, and including: means for maintaining a fluid seal between the fluid coupling and the associated respective conduit.
Claim 7
Dependent Claim
33 words
Apparatus, as set forth in claim 5, wherein the sealing means comprises an O-ring positioned in the annulus between the associated respective conduit and the fluid coupling on opposed sides of the chamber.
