Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
An internal combustion engine having a cylinder block, a crankcase member affixed to one end of said cylinder block, an output shaft rotatably journaled by said engine and having a starter gear affixed thereto in exposed relationship at one side of said engine, a mounting plate mounted in spaced relationship to said crankcase member and on the side thereof opposite to said cylinder block for defining a cooling air gap therebetween, and a starter motor mounted on said mounting plate on the side of said mounting plate facing away from said crankcase member and operably engaged with said engine output shaft starter gear for effecting electrical starting of said engine.
Claim 2
Dependent Claim
110 words
An internal combustion engine having a cylinder block, a crankcase member affixed to one end of said cylinder block, an output shaft rotatably journaled by said engine and having a starter gear affixed thereto in exposed relationship at one side of said engine, a mounting plate mounted in spaced relationship to said crankcase member and on the side thereof opposite to said cylinder block for defining a cooling air gap therebetween, and a starter motor mounted on said mounting plate on the side of said mounting plate facing away from said crankcase member and operably engaged with said engine output shaft starter gear for effecting electrical starting of said engine.
Claim 3
Dependent Claim
112 words
An internal combustion engine having a cylinder block, a crankcase member affixed to one end of said cylinder block, an output shaft rotatably journaled by said engine and having a starter gear affixed thereto in exposed relationship at one side of said engine, a mounting plate mounted in spaced relationship to said crankcase member for defining a cooling air gap therebetween, and a starter motor mounted on said mounting plate on a side thereof said mounting plate being spaced from said crankcase member by bosses formed on one of the mounting plate and crankcase member and operably engaged with said engine output shaft starter gear for effecting electrical starting of said engine.
Claim 4
Dependent Claim
112 words
An internal combustion engine having a cylinder block, a crankcase member affixed to one end of said cylinder block, an output shaft rotatably journaled by said engine and having a starter gear affixed thereto in exposed relationship at one side of said engine, a mounting plate mounted in spaced relationship to said crankcase member for defining a cooling air gap therebetween, and a starter motor mounted on said mounting plate on a side thereof said mounting plate being spaced from said crankcase member by bosses formed on one of the mounting plate and crankcase member and operably engaged with said engine output shaft starter gear for effecting electrical starting of said engine.
