ABSTRACT:
The static balancing of a wheel is achieved quickly and in a simplified manner with the use of a scale device which is mounted alongside a rotatably mounted wheel. The scale device comprises an elongate deflectable pointer which is mounted at one end and extends in a cantilever manner alongside the wheel. A scale is mounted alongside the elongate deflectable pointer and indicia is provided on the scale indicating the amount of weight needed to be added to the wheel in order to bring the wheel into balance. A finger is provided which is adapted to be secured to the wheel at a selected circumferential location in relation to the heaviest point on the wheel and having a portion projecting laterally from the wheel for engaging and deflecting the pointer whereby the amount of deflection of the pointer can be read directly from the scale and the amount of weight needed to bring the wheel into balance can be readily determined, thus greatly reducing the amount of time required for balancing the wheel.
