These are mounted on springs, thus securing immunity from vibration troubles. The controller is of the seriesparallel type, giving four speeds forward and two reverse speeds. It is instantly accessible by means of a springcontrolled hinged door. The use of two mots provides a perfect differential action.
The battery equipment consists of 14 lead cells or 60 nickel-iron cells, according to conditions of service. There are two brake systems, including an emergency set. The condition of the battery is indicated by a meter, and an automatic charging switch cute off the supply when the battery is fully charged. Axles are, of nickel-chrome steel. •
Every chassis is subjected fo a fullload-capacity test under severe cosidibons before -being finally passed, and it should be noted that in this design the usual transmission features are eliminated, i.e., there are no chains, universal joints, differential gear, or bevels.
Special attention has been paid to lubrication, and the weather-proof qualities of the chassis.
The method of springing the motors is interesting. They are pivoted on the rear axle, being supported by balanced springs attached to the frame. They move in an arc, the radius of which Is the same as the distance between the centres of the internal gear and the driving pinions.
