Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 135 words
For use in combination with a snowmobile having an engine and an engine air intake on said engine, the improvement comprising an intake duct and tool box combination for carrying air to said engine air intake comprising a housing having outer walls defining a passageway, said housing having a main portion, an elbow section leading from said main portion of said housing to said engine air intake and being open to said passageway, connection means to connect said engine air intake to said elbow section, an upper wall of said housing having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by walls spaced from said outer walls on sides of said housing other than the upper wall, and cover means to cover said upwardly open receptacle.
Claim 2
Dependent Claim 135 words
For use in combination with a snowmobile having an engine and an engine air intake on said engine, the improvement comprising an intake duct and tool box combination for carrying air to said engine air intake comprising a housing having outer walls defining a passageway, said housing having a main portion, an elbow section leading from said main portion of said housing to said engine air intake and being open to said passageway, connection means to connect said engine air intake to said elbow section, an upper wall of said housing having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by walls spaced from said outer walls on sides of said housing other than the upper wall, and cover means to cover said upwardly open receptacle.
Claim 3
Dependent Claim 187 words
For use in combination with a snowmobile having an engine and an engine air intake on said engine, the improvement comprising an air intake duct and tool box combination for carrying air to said air intake duct comprising a housing having outer walls defining a passageway, the uppermost of said walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by walls spaced from said outer walls on sides of said duct other than the upper side, wherein said housing has an outlet opening and a main body portion that is at substantially right angles to the axis of the outlet opening from said housing, said main body portion being of substantially greater cross-sectional area than said outlet opening, and said receptacle protruding into said main body portion, so that the passageways defined in the interior of said main body portion between said walls forming said receptacle and the walls forming said main body portion are of at least equal cross-sectional area to the area of the outlet opening, and cover means to cover said upwardly opening receptacle.
Claim 4
Dependent Claim 187 words
For use in combination with a snowmobile having an engine and an engine air intake on said engine, the improvement comprising an air intake duct and tool box combination for carrying air to said air intake duct comprising a housing having outer walls defining a passageway, the uppermost of said walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by walls spaced from said outer walls on sides of said duct other than the upper side, wherein said housing has an outlet opening and a main body portion that is at substantially right angles to the axis of the outlet opening from said housing, said main body portion being of substantially greater cross-sectional area than said outlet opening, and said receptacle protruding into said main body portion, so that the passageways defined in the interior of said main body portion between said walls forming said receptacle and the walls forming said main body portion are of at least equal cross-sectional area to the area of the outlet opening, and cover means to cover said upwardly opening receptacle.
Claim 5
Dependent Claim 26 words
The combination as specified in claim 2 wherein said housing uppermost wall has additional receptacles molded therein for holding spark plugs and a spark plug wrench.
Claim 6
Dependent Claim 19 words
The combination as specified in claim 3 wherein said housing is a molded assembly made of a plastic material.
Claim 7
Dependent Claim 154 words
For use in combination with a snowmobile having a frame, an operator's area on the frame including foot supports, an engine, a cooling air intake for said engine, and means to mount said engine adjacent the forward end of said frame, the improvement comprising an air intake duct and tool box combination for carrying air to said air intake duct comprising a housing having outer walls defining a passageway, means to position said housing adjacent a lateral side of the engine, said passageway having an inlet adjacent a foot support of said snowmobile and having an outlet connected to the air intake, an upper one of said outer walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by receptacle walls spaced from said outer walls on sides of said housing other than the upper side, and cover means to cover said upwardly opening receptacle.
Claim 8
Dependent Claim 154 words
For use in combination with a snowmobile having a frame, an operator's area on the frame including foot supports, an engine, a cooling air intake for said engine, and means to mount said engine adjacent the forward end of said frame, the improvement comprising an air intake duct and tool box combination for carrying air to said air intake duct comprising a housing having outer walls defining a passageway, means to position said housing adjacent a lateral side of the engine, said passageway having an inlet adjacent a foot support of said snowmobile and having an outlet connected to the air intake, an upper one of said outer walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by receptacle walls spaced from said outer walls on sides of said housing other than the upper side, and cover means to cover said upwardly opening receptacle.
Claim 9
Dependent Claim 147 words
For use in combination with a snowmobile having an engine and an air intake on said engine, the improvement comprising an air intake duct and tool box combination for carrying air to said engine air intake duct comprising a housing having outer walls defining a passageway having an inlet opening adjacent one end thereof and an outlet connected to the engine air intake, the uppermost or said outer walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by receptacle walls spaced from said outer walls on sides of said housing other than the upper side, and said receptacle walls including a wall adjacent the inlet opening and forming a baffle to cause a change in direction of flow of a substantial portion of the air entering the inlet, and cover means to cover said upwardly opening receptacle.
Claim 10
Dependent Claim 147 words
For use in combination with a snowmobile having an engine and an air intake on said engine, the improvement comprising an air intake duct and tool box combination for carrying air to said engine air intake duct comprising a housing having outer walls defining a passageway having an inlet opening adjacent one end thereof and an outlet connected to the engine air intake, the uppermost or said outer walls having a receptacle defined therein and extending into the passageway, said receptacle being upwardly open and being defined by receptacle walls spaced from said outer walls on sides of said housing other than the upper side, and said receptacle walls including a wall adjacent the inlet opening and forming a baffle to cause a change in direction of flow of a substantial portion of the air entering the inlet, and cover means to cover said upwardly opening receptacle.
Claim 11
Dependent Claim 45 words
The combination as specified in claim 6 wherein said walls defining said receptacle include walls cooperating with said housing to define an airflow path that changes direction at least one additional time between the wall forming a baffle and the air intake on said engine.
