Abstract
Abstract In a vehicle such as a trailer, carriage, wagon, or the like, the front axle or frame of the vehicle proximate each front wheel assembly includes a first axle which is pivotally mounted thereto and disposed to provide for turning of the wheel, while a second axle pivotally mounts to the first axle to provide for limited wheel shifting forwardly or rearly of the first axle, one of said axles having an angular formation to acquire camber, which camber translates into wheel toe-in due to this pivotal movement of the second axle to thereby facilitate the guidance of said vehicle while being moved in either the forward or reverse direction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
In facilitating the directional movement of a vehicle through the arrangement of its front wheel assemblies to follow a guided course of travel comprising, a vehicle including a supporting frame for mounting of its wheel assemblies, each wheel assembly including a first axle pivotally mounting to said frame and maintaining an angular relationship with the frame to which it mounts to thereby achieve wheel camber, a second axle rotatably supporting a wheel and being mounted for limited forward and reverse pivotal movement to said first axle to thereby achieve wheel toe-in in the direction of vehicle movement.
Claim 2
Dependent Claim
97 words
In facilitating the directional movement of a vehicle through the arrangement of its front wheel assemblies to follow a guided course of travel comprising, a vehicle including a supporting frame for mounting of its wheel assemblies, each wheel assembly including a first axle pivotally mounting to said frame and maintaining an angular relationship with the frame to which it mounts to thereby achieve wheel camber, a second axle rotatably supporting a wheel and being mounted for limited forward and reverse pivotal movement to said first axle to thereby achieve wheel toe-in in the direction of vehicle movement.
Claim 3
Dependent Claim
67 words
The invention of claim 1 wherein said first axle includes a stop means fixed to its end, said second axle having a sleeve means formed on one end and being mounted for limited pivotal movement upon the end of said first axle, said sleeve including a shoulder means cooperating with said stop means to limit the extent of the forward and reverse pivot of said second axle.
Claim 4
Dependent Claim
65 words
The invention of claim 2 and including a camming member loosely mounted with respect to said second axle, said wheel having a drum connecting thereto and disposed surrounding said second axle and camming member, and a roller arranged intermediate said camming member and drum to effect the limited forward and reverse pivot of said second axle as the vehicle initiates movement in an opposite direction.
Claim 5
Dependent Claim
27 words
The invention of claim 3 wherein said camming member includes a track, and said roller is formed having a corresponding groove to ride upon said cam track.
Claim 6
Dependent Claim
86 words
In the methOd of facilitating the directional movement of a vehicle through the arrangement of its wheels to follow a guided course of movement comprising, mounting a front pair of wheels upon the vehicle to achieve camber wherein said wheels are closer together at the bottom than at the top, pivotally mounting the axle supporting each wheel whereby the axle leads the wheel and achieves toe-in in the direction of vehicle movement, and moving said vehicle to simultaneously achieve camber and toe-in to enhance vehicle guidance.
Claim 7
Dependent Claim
86 words
In the methOd of facilitating the directional movement of a vehicle through the arrangement of its wheels to follow a guided course of movement comprising, mounting a front pair of wheels upon the vehicle to achieve camber wherein said wheels are closer together at the bottom than at the top, pivotally mounting the axle supporting each wheel whereby the axle leads the wheel and achieves toe-in in the direction of vehicle movement, and moving said vehicle to simultaneously achieve camber and toe-in to enhance vehicle guidance.
Claim 8
Dependent Claim
114 words
In facilitating the directional movement of a vehicle through the arrangement of its front wheel assemblies to follow a guided course of travel comprising, a vehicle including a supporting frame for mounting of said wheel assemblies, each wheel assembly including a pair of axles, a first axle being pivotally mounted to said frame, a second axle rotatably supporting a wheel and being mounted for limited forward and reverse pivotal movement to said first axle, one of said axles maintaining an angular relationship with respect to said frame to achieve camber of the mounted wheel, whereby said wheel camber translates partially into wheel toe-in as the second axle reaches the limit of its pivotal movement.
Claim 9
Dependent Claim
114 words
In facilitating the directional movement of a vehicle through the arrangement of its front wheel assemblies to follow a guided course of travel comprising, a vehicle including a supporting frame for mounting of said wheel assemblies, each wheel assembly including a pair of axles, a first axle being pivotally mounted to said frame, a second axle rotatably supporting a wheel and being mounted for limited forward and reverse pivotal movement to said first axle, one of said axles maintaining an angular relationship with respect to said frame to achieve camber of the mounted wheel, whereby said wheel camber translates partially into wheel toe-in as the second axle reaches the limit of its pivotal movement.
