JACKING SYSTEMS

At least half-a.dozen patent jacks for- permanent attachment to the car have been offcrng i" Great Britain and some of the builders of better class bodies have selected one of hos e devices as a standard fitting. The simplest form of attached jacks i:e secured to the running boards. A •:et is installed on each side of the car about midway between the front and mck wheols. When it is desired to jack up the wheels, the lifter portion of the jack is dropped into a vertical position. A convement winding handle is then fitted into a socket and both back and front wheels one one side of the car are lifted clear of the ground. Another form consists of a species of large cam one of which is attached to each axle. When it is desired to lift a wheel a cam is dropped until it touches the ground, and if the car is given a light touch on the clutch it will lift one side clear of the ground on the high edge of the cam The most novel jacking system yet evolved is a pneumatic apparatus attached near each wheel. In appearance the devices are like four com. rnon hydraulic jacks. The greatest feature is that the jacks can bo brought into operation from the I driver's seat by a remarkable array of soda syphon sparklet bulbs containing compressed gas. On tho instrument, board a' magazine of eight bulbs is fitted, and tubing connects with the jacks. The operation of a jack is very similar to the aeration of a soda syphon. By pressing a lever the- driver release* the gas into any chosen jack. A light car will
