Abstract
Abstract An enclosure, in the form of a mold, attached to the hood or cowling of a vehicle engine, having an air inlet integral with the hood or cowling, combines with the hood to form passages for flow of combustion air to the engine as it passes through the mold. The mold provides cold air to the engine, and in combination with a boot provides control of noise emanating from the engine while being attached to and movable with the hood to provide access to the engine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
In a vehicle having an engine with a covering and an inlet therein, apparatus for directing combustion air going to and sound waves emanating from the engine comprising: a single piece enclosure attached to and movable with the covering having an opening therein; an open face on said enclosure for engagement with the covering, said enclosure including an inner portion within and spaced from the outer periphery of said open face extending toward the covering to form passages for directing the flow of air, and extending away from the covering to form a plenum for receiving said flow of air from said passages and slowing the velocity of incoming air directed to the engine while also dispersing sound waves; and means for sealing by contact the opening of said enclosure to the engine, said open face of said enclosure being connected to the inlet to cause outside air to be directed to the engine and to isolate the sound waves traveling through said enclosure.
Claim 2
Dependent Claim
164 words
In a vehicle having an engine with a covering and an inlet therein, apparatus for directing combustion air going to and sound waves emanating from the engine comprising: a single piece enclosure attached to and movable with the covering having an opening therein; an open face on said enclosure for engagement with the covering, said enclosure including an inner portion within and spaced from the outer periphery of said open face extending toward the covering to form passages for directing the flow of air, and extending away from the covering to form a plenum for receiving said flow of air from said passages and slowing the velocity of incoming air directed to the engine while also dispersing sound waves; and means for sealing by contact the opening of said enclosure to the engine, said open face of said enclosure being connected to the inlet to cause outside air to be directed to the engine and to isolate the sound waves traveling through said enclosure.
Claim 3
Dependent Claim
61 words
The apparatus defined in claim 1 wherein said enclosure includes an entry internal of said enclosure for passage of air to the opening of said enclosure, said entry located in said inner portion extending toward the covering to permit shielding said entry from the inlet by said inner portion to reduce the noise level at the inlet originating from said entry.
Claim 4
Dependent Claim
18 words
The apparatus defined in claim 1 wherein said enclosure includes a snout containing the opening in said enclosure.
Claim 5
Dependent Claim
19 words
The apparatus defined in claim 1 including a seal for sealing a portion of said enclosure to the covering.
Claim 6
Dependent Claim
34 words
The apparatus defined in claim 1 wherein said means for sealing includes a boot for selectively sealing the connection of said boot to said enclosure to permit said enclosure to move with the covering.
Claim 7
Dependent Claim
24 words
The apparatus defined in claim 1 wherein said enclosure is adaptable to receive air flow directing vanes located within said opening of said enclosure.
Claim 8
Dependent Claim
113 words
The apparatus defined in claim 1 wherein said enclosure is a single piece mold and said sealing means is a boot, said inner portion including a ridge, said ridge encompassing the upper portion of said plenum and being connected thereto by an inner partition, said mold further including an outer partition and a pan shaped portion, said outer partition interconnecting said ridge with said pan, at least a portion of the perimeter of said inner and outer partitions being cut away to form said entry into said plenum above said pan, said outer partition, pan shaped portion and the covering combining to form devious passages for the flow of air from said inlet.
Claim 9
Dependent Claim
26 words
The apparatus defined in claim 7 including a snout on said plenum having cylindrical and conical portions, said conical portion adapted to seat within said boot.
Claim 10
Dependent Claim
146 words
In apparatus for a vehicle with an engine and a covering therefor, the apparatus directing combustion air going to and sound waves emanating from the engine and being located between the covering having an inlet therein and means for sealing the apparatus to the engine, a single piece mold comprising: an open face on said mold for engagement with the covering; an inner portion within and spaced from the outer periphery of said open face extending toward the covering to form passages for directing the flow of air; a plenum formed by extending said inner portion away from the covering for slowing the velocity of incoming air and dispersing sound waves; and an entry internal of said mold located in said inner portion to shield said entry from the inlet by said inner portion to reduce the noise level at the inlet origiNating from said entry.
Claim 11
Dependent Claim
146 words
In apparatus for a vehicle with an engine and a covering therefor, the apparatus directing combustion air going to and sound waves emanating from the engine and being located between the covering having an inlet therein and means for sealing the apparatus to the engine, a single piece mold comprising: an open face on said mold for engagement with the covering; an inner portion within and spaced from the outer periphery of said open face extending toward the covering to form passages for directing the flow of air; a plenum formed by extending said inner portion away from the covering for slowing the velocity of incoming air and dispersing sound waves; and an entry internal of said mold located in said inner portion to shield said entry from the inlet by said inner portion to reduce the noise level at the inlet origiNating from said entry.
