Abstract

The supply trolley overcomes difficulties to small diameter wheels which prevent the use of normal type brake gear. The drawbar of the trolley is inclined to a small angle up or down and this is used to operate the brake gear. The system consists of a wheel (2) and a moving cam (13) on an axis parallel to that of the wheel. The cam can contact the wheel and is held in the "off" position by a spring (19). The cam shaft has a pinion which engages with a rack operated by the drawgear. This arrangement can be repeated on each side of the wheel (for both directions of movement) and on both sides of the vehicle.
