Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 219 words
In a road vehicle, provided with a running gear in the form of a wheel suspension system with one of the wheels being a steering wheel mounted for horizontal turning about a turning axis by a pitman arm connected thereto, and having a steering system which includes a rod assembly connected for moving the pitman arm, the improvement comprising: a steering gear stabilizer apparatus for resisting turning movement of the steering wheel about the turning axis; said stabilizer apparatus comprising a single fixed mounting bracket, a shaft having opposed ends, compression springs, a universal joint, spring retainers, and a movable mounting bracket; means by which said shaft is reciprocatingly received in supported relationship respective to said fixed mounting bracket; said springs being spaced from one another by said fixed mounting bracket; said spring retainers being affixed to opposed ends of said shaft in a position to bias each of said springs towards said fixed mounting bracket; said universal joint connecting one end of said shaft to said movable bracket; means by which said movable mounting bracket is affixed to said steering system; means by which said fixed mounting bracket is connected in fixed relationship with respect to said movable bracket; so that turning movement of the wheel about the turning axis is resisted by one of said compression springs.
Claim 2
Dependent Claim 219 words
In a road vehicle, provided with a running gear in the form of a wheel suspension system with one of the wheels being a steering wheel mounted for horizontal turning about a turning axis by a pitman arm connected thereto, and having a steering system which includes a rod assembly connected for moving the pitman arm, the improvement comprising: a steering gear stabilizer apparatus for resisting turning movement of the steering wheel about the turning axis; said stabilizer apparatus comprising a single fixed mounting bracket, a shaft having opposed ends, compression springs, a universal joint, spring retainers, and a movable mounting bracket; means by which said shaft is reciprocatingly received in supported relationship respective to said fixed mounting bracket; said springs being spaced from one another by said fixed mounting bracket; said spring retainers being affixed to opposed ends of said shaft in a position to bias each of said springs towards said fixed mounting bracket; said universal joint connecting one end of said shaft to said movable bracket; means by which said movable mounting bracket is affixed to said steering system; means by which said fixed mounting bracket is connected in fixed relationship with respect to said movable bracket; so that turning movement of the wheel about the turning axis is resisted by one of said compression springs.
Claim 3
Dependent Claim 19 words

Claim 7
Dependent Claim 171 words
In combination with a steerable vehicle having a steerable wheel supporting the vehicle and turnable about a turning axis, a stabilizer apparatus, said stabilizer apparatus comprising a single fixed mounting bracket, a shaft having opposed ends, compression springs, a universal joint, spring retainer, and a movable mounting bracket; means by which said shaft is reciprocatingly received in supported relationship respective to said fixed mounting bracket; said springs being spaced from one another by said fixed mounting bracket; said spring retainers being affixed to opposed ends of said shaft in a position to bias each of said springs towards said fixed mounting bracket; said universal joint connecting one end of said shaft to said movable bracket; means by which said movable mounting bracket can be connected to said steering system; means by which said fixed mounting bracket can be connected to said vehicle in fixed relationship with respect to said movable bracket; so that turning movement of the steerable wheel about the turning axis is resisted by one of said compression springs.
Claim 8
Dependent Claim 171 words
In combination with a steerable vehicle having a steerable wheel supporting the vehicle and turnable about a turning axis, a stabilizer apparatus, said stabilizer apparatus comprising a single fixed mounting bracket, a shaft having opposed ends, compression springs, a universal joint, spring retainer, and a movable mounting bracket; means by which said shaft is reciprocatingly received in supported relationship respective to said fixed mounting bracket; said springs being spaced from one another by said fixed mounting bracket; said spring retainers being affixed to opposed ends of said shaft in a position to bias each of said springs towards said fixed mounting bracket; said universal joint connecting one end of said shaft to said movable bracket; means by which said movable mounting bracket can be connected to said steering system; means by which said fixed mounting bracket can be connected to said vehicle in fixed relationship with respect to said movable bracket; so that turning movement of the steerable wheel about the turning axis is resisted by one of said compression springs.
Claim 9
Dependent Claim 19 words
The combination of claim 6 wherein said fixed mounting bracket is affixed to the main frame of the vehicle.
Claim 10
Dependent Claim 18 words
The combination of claim 6 wherein said fixed mounting bracket is affixed to a cross-member of the vehicle.
Claim 11
Dependent Claim 19 words
The combination of claim 6 wherein said movable bracket is affixed to the pitman arm of the steering system.
Claim 12
Dependent Claim 19 words
