A torque rod of pressed steel and of tapering channel section is fitted. It is anchored by a spring loaded ball joint at the front end and is provided with a vertical pin joint at the rear end, where it is attached to the axle. No. radius rods are used. Springs. The springing of the car is not good from our point of view, the springs being very hard and not flexible. The rear springing is by no means of side and transverse springs, the side springs being 2¼" wide x 55" long. The front springs are unusual in that the front axle is not attached midway. The distance from the front spring eye to the axle being 18" and from the axle to the rear eye being 23". The spring width is 2¼". Front Axle and Steering Gear. The front axle is of 1 section of usual design. The wheels which ate of wood carry detachable rims on which are mounted tyres 36" x 4½". The hubs are mounted on Timpkin taper roller bearings and are adjustable for slack. The steering is of the worm and nut type. It is rather tiring to drive as the steering is not self centring and one has to hold the wheel continually and the car is inclined to "wander". The pendulum lever is 12¼" long which is rather unusual and points to the worm and not being a slow pitch. This exaggerates the play of the front wheels for a given amount of slack in the worm and nut and is probably the cause of the car tending to "wander" and requiring continuous correction at the steering wheel.
