Abstract
Abstract A leveling apparatus for a motor driven vehicle having its blade arranged on a rotating plane disposed beneath a triangularly shaped pivot seat wherein its front end is extended in a ball joint on the chassis of the vehicle and wherein the opposite ends are suspended via ball joints and pivotably arranged on hoists which are freely supported in all directions and mounted on the vehicle chassis so that coupled to the front end of the pivot seat is a bolt casing which receives a bolt containing a ball at its end for the ball joint suspension, the axis of the ball being displaced from the axis of the bolt contained within the bolt casing so that when the bolt is pivoted, the height of the vehicle chassis can be adjusted accordingly.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
In a levelling apparatus for a vehicle having a blade arranged on a rotating plate disposed beneath a triangular-shaped pivot seat, wherein a front end of said seat is connected to the chassis of the vehicle by universal means, and wherein two opposite ends of said seat are suspended via ball joints and pivotably arranged on hoisting means which are freely supported in all directions and slidably mounted on the vehicle chassis, said universal means comprising; a bolt having an axis, a front end and a rear end, a bearing casing pivotably encasing said bolt and secured to the triangularly shaped pivot seat so that the axis of said bolt lies along the direction of the vehicle movement, a ball having an axis in in the direction of vehicle movement, serving as the front ball joint connection to said chassis and coupled to the front end of said bolt, the axis of said ball being displaced and parallel with respect to the axis of said bolt, and means associated with said bolt and said bearing casing for arresting the pivotal movement of said bolt with respect to the bearing casing.
Claim 2
Dependent Claim
190 words
In a levelling apparatus for a vehicle having a blade arranged on a rotating plate disposed beneath a triangular-shaped pivot seat, wherein a front end of said seat is connected to the chassis of the vehicle by universal means, and wherein two opposite ends of said seat are suspended via ball joints and pivotably arranged on hoisting means which are freely supported in all directions and slidably mounted on the vehicle chassis, said universal means comprising; a bolt having an axis, a front end and a rear end, a bearing casing pivotably encasing said bolt and secured to the triangularly shaped pivot seat so that the axis of said bolt lies along the direction of the vehicle movement, a ball having an axis in in the direction of vehicle movement, serving as the front ball joint connection to said chassis and coupled to the front end of said bolt, the axis of said ball being displaced and parallel with respect to the axis of said bolt, and means associated with said bolt and said bearing casing for arresting the pivotal movement of said bolt with respect to the bearing casing.
Claim 3
Dependent Claim
75 words
The levelling apparatus as recited in claim 1, wherein said arresting means comprises; a first toothed disc fixedly mounted to said ball, adjacent to said bolt, a second toothed disc fixedly mounted to the front end of said bearing casing having its toothed surface arranged for engagement with the toothed surface of said first toothed disc, and means for securing together said first and second toothed discs to arrest the pivotable movement of said bolt.
Claim 4
Dependent Claim
69 words
The levelling apparatus as recited in claim 2, wherein said securing means comprises; a cover member disposed over the rear end of said bolt and in contact with the rear end of said casing, said cover member including an axial bore, and a stud fastener disposed within said axial bore and threadably engaged to the rear end of said bolt, said fastener being in axial alignment with said bolt.
Claim 5
Dependent Claim
34 words
The levelling apparatus as recited in claim 3 which additionally comprises adjusting facets disposed around the axis of said bolt for receiving a wrench, said facets being disposed between said ball and said bolt.
