A New Clutch which Provides Smooth Pick-up

INGENIOUS CLUTCH PLATE DEVELOPED BY NOEL NEWTON

MANY of the new British cars are fitted with an ingenious form of clutch plate developed by Mr. Noel Newton, of Newton and Bennett, Ltd. Although designed in the first place for use with the well-known Newton centrifugal clutch, this plate can also be employed in an ordinary foot-operated mechanism. It is designed in such a way as to give a very gentle pick-up or progressive engagement, making it easy for the driver to move off smoothly.
Two steel plates are employed, carrying Ferodo linings, and are spaced by a series of circular washers as shown in a sectioned drawing reproduced. Each washer is held in place by a rivet which also serves to secure the linings. The washers are of spring steel, slightly dished, the curvature being arranged first in one direction and then in the other, alternately. As a result, when the clutch begins to engage, the spring load has to squeeze the washers and is therefore gently applied to the friction surfaces. An incidental advantage of the design is that the slots and holes in the two plates enable air to circulate and provide a certain degree of cooling.
In this connection it is of interest to mention that the Newton centrifugal clutch, while still employing the same principle, has been greatly simplified in design and construction. Only three weighted units are now employed, and owing to the leverage provided the weights are much lighter than in the previous Newton clutch. Furthermore, it is found necessary to use only a single plate of the new type described. This clutch is used in conjunction with the self-changing gearbox by several manufacturers, notably by Riley and Crossley.
