Abstract
Abstract Apparatus for pivotally interconnecting a force applying member to an apparatus for repairing and straightening is disclosed in its preferred form for use in repairing and straightening the body and frame of a vehicle. The disclosed apparatus includes a small cylindrical pivot member mounted in a first stationary position located adjacent the front of an apparatus for repairing and straightening and second and third small cylindrical pivot members mounted to a tram movable within the apparatus for repairing and straightening. A force applying member in the form of an elongatable pull tower is shown together with a connector arm which extends from the pull tower to a point adjacent to the pivot member. A clamp member and a ring sleeve type bearing are provided according to the present invention to pivotally mount the connector arm to one of the pivot members. Thus, under the teachings of the present invention, the counterforces applied to the connector arm by the pull tower can be conveyed to the pivot member from any direction. Further provided according to the present invention are positioning and leveling members including a thrust plate and adjustment screws which abut with the thrust plate. A nylon type bearing is also provided between the thrust plate and the clamp member to reduce the amount of friction between the thrust plate and the clamp member when the connector arm is pivoted about pivot member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
Apparatus for pivotally interconnecting force applying means to an apparatus for repairing and straightening the body and frame of a wheeled vehicle comprising, in combination: a small cylindrical pivot member mounted to the apparatus for repairing and straightening; a connector arm extending from the force applying means to a point adjacent the pivot member; and means for pivotally mounting the connector arm to the pivot member and for allowing the counterforce applied to the connector arm by the force applying means to be conveyed to the pivot member from any direction comprising, in combination: a first clamp member pivotably connected about the pivot member; a first ring-sleeve type bearing located between the first clamp member and the pivot member; a second clamp member pivotably connected about the pivot member and spaced from the first clamp member; a second ring-sleeve type bearing located between the second clamp member and the pivot member; and means for positioning and leveling the connector arm on the pivot member comprising, in combination: a thrust plate; and adjustment screws abutting the thrust plate, wherein the means for pivotally mounting the connector arm to the pivot member and for allowing the counterforce applied to the connector arm by the force applying means to be conveyed to the pivot member from any direction operatively rests on the thrust plate.
Claim 2
Dependent Claim
