Abstract
Abstract A fuel tank and hydraulic reservoir are provided with a contiguous outer wrap with spaced side walls to define an air baffle therebetween. The baffle is an open channel communicating with the engine compartment so that air flows through the channel as a result of the pressure differential created by the engine driven fan within the compartment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
A compact arrangement for mounting the fuel tank and hydraulic reservoir on a vehicle comprising: a vehicle frame; an engine mounted on said frame; shroud means partially surrounding the engine and forming a semi-enclosed engine compartment; a fan driven by the engine and capable of creating a pressure differential between the compartment and ambient pressures; means mounting said fuel tank and said hydraulic reservoir on said frame adjacent said shroud means; said tank and reservoir having facing side members; said members being spaced apart to form an open channel; one end of said channel communicating with the interior of said compartment and the other end of said channel being exposed to ambient atmosphere; whereby flow of air through the channel is created by said pressure differential to minimize the transfer of heat between said reservoir and said tank.
Claim 2
Dependent Claim
138 words
A compact arrangement for mounting the fuel tank and hydraulic reservoir on a vehicle comprising: a vehicle frame; an engine mounted on said frame; shroud means partially surrounding the engine and forming a semi-enclosed engine compartment; a fan driven by the engine and capable of creating a pressure differential between the compartment and ambient pressures; means mounting said fuel tank and said hydraulic reservoir on said frame adjacent said shroud means; said tank and reservoir having facing side members; said members being spaced apart to form an open channel; one end of said channel communicating with the interior of said compartment and the other end of said channel being exposed to ambient atmosphere; whereby flow of air through the channel is created by said pressure differential to minimize the transfer of heat between said reservoir and said tank.
Claim 3
Dependent Claim
86 words
A compact arrangement according to claim 1, wherein said tank and reservoir each comprises: a pair of side walls engageable with and secured to the associated side member; a wrap member is secured to said side walls and said side member to form the bottom, outer wall, and top of the respective tank and reservoir; each wrap member extending beyond the associated side member toward the other side member; and means securing the wrap members together to form said channel and to provide a unitary structure.
Claim 4
Dependent Claim
40 words
A compact arrangement according to claim 2, wherein said mounting means comprises: a pair of legs secured to said structure and extending downward therefrom; and fastening means for detachably securing the lower end of said legs to said vehicle frame.
Claim 5
Dependent Claim
37 words
A compact arrangement according to claim 3, wherein one of said legs is secured to the wrap member for the fuel tanK and the other of said legs is secured to the wrap mamber for the reservoir.
Claim 6
Dependent Claim
30 words
A compact arrangement according to claim 4, wherein the upper surfaces of said wrap members are contiguous both with each other and with the upper surface of said shroud means.
Claim 7
Dependent Claim
118 words
A unitary fuel tank and hydraulic reservoir structure comprising: a tank side member; a pair of tank side walls secured to the tank side member; a tank wrap member secured to the outer edges of said tank side walls and member; said tank wrap member having upper and lower extensions; a reservoir side member; a pair of reservoir side walls secured to the reservoir side member; a reservoir wrap member secured to the outer edges of said reservoir side walls and member; said reservoir wrap member having upper and lower extensions; means securing the corresponding extensions together; said extensions and said side members forming an open channel; and fan means for causing air to flow through said channel.
Claim 8
Dependent Claim
118 words
A unitary fuel tank and hydraulic reservoir structure comprising: a tank side member; a pair of tank side walls secured to the tank side member; a tank wrap member secured to the outer edges of said tank side walls and member; said tank wrap member having upper and lower extensions; a reservoir side member; a pair of reservoir side walls secured to the reservoir side member; a reservoir wrap member secured to the outer edges of said reservoir side walls and member; said reservoir wrap member having upper and lower extensions; means securing the corresponding extensions together; said extensions and said side members forming an open channel; and fan means for causing air to flow through said channel.
Claim 9
Dependent Claim
30 words
A unitary structure according to claim 6 wherein said unitary structure is mounted on a vehicle having an engine and said fan means consists of a conventional engine-driven cooling fan.
Claim 10
Dependent Claim
30 words
A unitary structure according to claim 7, wherein said engine is partially enclosed by shroud means and said unitary structure cooperates with said shroud means to further enclose said engine.
