made as small as desired to give the required resistance to rolling. The same principle can be employed mechanically.

PRINCIPAL OF HYDRAULIC ANTI-ROLLING DEVICE
CHASSIS FRAME

The objection to anti-rolling devices is that it is not always desirable that the axle should move parallel to the frame, more especially when one wheel only is negotiating a bump. Such fitments therefore are liable to promote harsh riding under certain conditions.

V.{VIENNA} UNCONVENTIONAL SUSPENSIONS.

(a) Helical springs with fluid friction.

From previous remarks it will have been gathered that helical springs with fluid damping present a very promising field for improved suspension. The main advantage of helical springs is that they are light, have no internal friction and can be used in series and so provide a variable rating suspension.
