Static wheel balancer

Abstract From the Canadian patent

The wheel balancer includes a plastic onepiece body having means for mounting on the shaft of the wheel and also means defining a window. A bar is carried by the body and is slidable therein to a position where the wheel is in balance, whereupon indicia on the bar, visible through the window, informs the mechanic how much weight is to be added to the wheel to place it in balance. The bar is also rotatable about its axis in the body, so that several labels corresponding to several wheel diameters can be provided on the same bar. The detent mechanism on the body and on the bar holds the bar in a selected rotational orientation while enabling the sliding movement during balancing.
