SHOCK ABSORBER

NEW INVENTION BY TWO NAPIER MEN A new stabliser attachment for motor cars, lorries etc, which has just been invented by two Napier men, is claimed to possess very unusual advantages and should prove of great value to owners of these vehicles. The invention embodies the old principle of mechanics known as the "lazy-tongs," • together with inter- 1 acting compensating levers, compression springs and slides. The device is capable of making the stan>dard car, or lorry, carry an extra load of from 4001b to one ton, while the strongest points in its favour is the fact that every time the car spring on one side is called upon to • deflect, the stabiliser makes it imperative that the load shall also be transmitted equally on to the spring | on the opposite side, thus dividing .the strain evenly between the two springs. In consequence of this both ! tyres adhere to the. ground surfaces instead of one rising during the tipping motion on the ordinary car, thus making. it a complete non-slcid attachment. The inventors claim. that spring breakage will be praetically eliminated where the stabiliser is fitted. , The device acts in two ways. As h a shock absorb er it retards the downthrust on the spring, and checks the up-kick, this latter movement being the one which causes breakages, because the bundle of spting leaves underneath the main- back leaf cannot assist the latter on the rebound, but i merely leaves the top leaf to do the work; hence the fractures. The owners and drivers of service cars will find, the inventors claim, what they have been looking for for ' many years — that is, something that : will carry that bit of extra weight, whether it be an extra passenger or two or luggage, without jeopardising the rear springs of their cars. The . terrible bugbear of car sickness will ' also be abolished, because the sideroll, which is the cause of ^this malady, will be checked. When the stabiliser is fitted motorists will attain more speed, greater economy in petrol consumption, and also less tyre wear, owing to the absence of wheel spin. Racing motorists will be able to make considerably better times, while ambulances, milk vans, etc., will travel more steadily and with greater speed. The patent has already been protected both in and outside of New Zealand.
