STAMP: Wm 19 NOV 1927 RECEIVED Dear Sir, "Spontan" Patent Transmission. This extract from the current issue of "Engineering" will interest you especially because it contains a description of a new departure in Motor Car design - the "Spontan" Patent Transmission. This is a novelty of real importance; its application to a Car enables a simplicity of operation that will go far to promote increased sales in the Motor Car Industry, as in every family each member will be able to drive with ease without any special training. From the description you will see that the whole operation, except the steering, is achieved with only one foot and in one single foot pedal movement. The starting-up of the Car, and, in that connection, the application of variation in the motive-power; the braking, or retarding; the reversing - all are effected in a single movement with only one foot. Brake action is attained in quite a new way, by spring force opposed by the foot. This has the advantage that the application of the Brakes is always effected with the same force, irrespective of the muscular strength of the driver. When the driver begins to lift his foot to release the pressure of the gas-pedal, he has only to allow the pedal, that is already in action, to continue its movement to a higher position, | ||
