Abstract: The device described is designed to balance wheels and comprises a tripod, an element sliding vertically and mounted upon the tripod, a supporting element serving to support the wheel to be balanced and supported, in turn, in one instance, by the vertically-sliding element, a suspension element mounted upon the tripod and comprising a lever extending above the supporting element, a connecting element uniting the supporting element to the lever and allowing it, in a second instance, to be supported in free suspension upon being released from the vertically-sliding element. A first reference mark is associated with the connecting element, and a second reference mark is associated with the supporting element. Wheel balancing is carried out by adding weights to the wheel until the two reference marks coincide.

Abstract: The apparatus comprises: a stand; a supporting element secured vertically thereto; locking elements mounted upon the supporting element for the purpose of securing the rim thereto; a release-rod adapted to pivot in relation to the supporting element and carrying, at one end, a head adapted to be inserted between the tire and the rim; force-reducing elements mounted rotatably upon the supporting element and upholding the rod, the elements comprising a lever-arm, successive partial rotation of which permits corresponding movements of lesser magnitude of the head of the rod; and locking elements making it possible to maintain a torque element which is stationary in relation to the supporting element during displacement of the release-rod.
