Abstract
A measuring bridge including extensible legs supporting the measuring bridge into position beneath a vehicle. The extensible legs each include a compression spring for upward movement into engagement with the bottom of a vehicle frame. The measuring bridge also includes apparatus for adjustably positioning the pointers of the measuring bridge to compensate for variations in the size of reference holes provided in the vehicle frame.
Claims11
A measuring bridge for determining the orientation of measured points on a motor vehicle with respect to reference points;
- the measuring bridge comprising:
- an elongated main beam;
- a pair of set-up beams connected to the elongated beam, the set-up beams being positioned in spaced apart parallel relation and extending generally perpendicularly to the elongated main beam, the set-up beams each including opposite ends, and the set-up beams and the elongated main beam being adapted to be positioned beneath a vehicle;
- vertically extending set-up pointers supported by the set-up beams and including upper ends adapted to engage reference points on the motor vehicle;
- means for connecting the set-up pointers to the set-up beams for adjustable movement along the length of the set-up beams;
- at least one measuring beam connected to the elongated main beam and extending generally perpendicularly to the elongated main beam;
- a measuring pointer supported by the measuring beam;
- and
- means for resiliently supporting the set-up beams such that the set-up pointers are selectively biased upwardly against the vehicle frame, the means for resiliently supporting including a plurality of extensible legs.

- a pair of set-up beams connected to the elongated beam, the set-up beams being positioned in spaced apart parallel relation and extending generally perpendicularly to the elongated main beam, the set-up beams each including opposite ends, and the set-up beams and the elongated main beam being adapted to be positioned beneath a vehicle;
- vertically extending set-up pointers supported by the set-up beams and including upper ends adapted to engage reference points on the motor vehicle;
- means for connecting the set-up pointers to the set-up beams for adjustable movement along the length of the set-up beams, the means for connecting including means for supporting the set-up pointers for vertical adjustable movement;
- at least one measuring beam connected to the elongated main beam and extending generally perpendicularly to the elongated main beam;
- and
- a measuring pointer supported by the measuring beam;
- the means for supporting the set-up pointers including a pointer support member supported by one of the beams, and the pointer support member including a central vertically extending bore adapted to house a pointer, and a compensating member surrounding the pointer support member, the compensating member being supported on the pointer support member for vertically adjustable movement, and means for adjusting the position of the compensating member with respect to the pointer support member, and the compensating member including a measurement scale.
