| Labour-free motoring at last JACKALL FOUR - WHEEL JACKING SYSTEM. The Jacking System of the Future VERY year motor-car manufacturers succeed in improving their products so that the motorist may ride care-free. Until now there has always remained the bugbear of grovelling on the ground with a dirty jack. The “JACKALL” System permanently, quickly and simply fixed to your car enables you to raise and lower any, or all wheels in a few seconds, without effort, without bending and without soiling your hands. The “JACKALL” consists of four small tubular hydraulic and telescopic jacks, permanently fitted close to each wheel and on both axles of the motor car. The control, a small flat box of about six inches square and three inches high, with an oil reservoir attached, is fitted to one or other of the running boards, and automatically operates each jack through flexible tubing. A hand lever works the hydraulic system, by means of which any one or all of the wheels can be raised without effort in a few seconds. Although the lifting power required may be over three tons, a child can work the system. This Four-Wheel Jack, being a permanent fixture, is, therefore, always ready and in position when required. ADVANTAGES 1. The apparatus is inexpensive, neat, strong and efficient and All British Made. 2. The Jacking System is always ready in position and produces no strain or distortion of the chassis. 3. The car cannot fall off the jacks, even if loaded, and can be left for long periods with tyres off the ground. 4. No drilling of the chassis is necessary and the maker’s guarantee is not thereby imperilled. 5. The “JACKALL” can be fitted to private cars and commercial vehicles of all sizes, and does not add unduly to the weight. 6. Car cleaning, greasing, oiling, washing, adjustment of brakes. etc., can be done more easily and quickly. 7. First cost is final cost, as it can be transferred from one car to another. 8. Passengers need not be disturbed when the jack is operated. The apparatus banishes, once and for all, the necessity of the so-called “mobile jack”—an accessory, at the best, both crude and antiquated. THE opinion of the experts is unanimous. The “JACKALL” must soon be standard equipment on every car. This amazing four-wheel jack, permanently fitted, will lift any one wheel in twelve seconds—all four wheels in fifty seconds. And this wonderful performance is achieved without effort, without any trouble. Just a touch on the lever of the “JACKALL” and up goes the car. Think of that! No more grovelling in the dirt—no more messing about with a dirty jack. The “JACKALL” does the work while you watch. Shortly a car without a “JACKALL” will be as out of date as a car without a self-starter. The “JACKALL” has made motoring perfect. It is a necessity that all can afford—and that all will want. “JACKALL” raises all 4 wheels off the ground in a few seconds WRITER and RACER join in praise MALCOLM CAMPBELL, world-famed Record Breaker writes:— “The nightmare of removing a wheel —especially when this has to be done in the dark—has now been entirely overcome by the ‘JACKALL’ system. The method of raising a car by the old system has been one of the greatest drawbacks to motoring in the past. I would as soon think of having a car without a self-starter as I would now a car without ‘JACKALL’.” KAYE DON declares:— “The ‘JACKALL’ is the answer to the prayers of every motorist who has ever had to change a wheel. “I would never have believed such simplicity and ease of operation possible had I not seen, used and owned a ‘JACKALL’ myself. “I can only be voicing the thought of all motorists when I say: Never again will I take out a car that is not fitted with a ‘JACKALL’.” JOHN DOUGLAS writes:— “Punctures no longer annoy me. They give me the pleasure of demonstrating my ‘JACKALL’ to astounded onlookers. In twelve seconds any wheel of my car can be off the ground. I take no credit for that remarkable performance. A child could do the same with a ‘JACKALL.’ The motorist who uses a car not fitted with a ‘JACKALL’ deserves all the backaches he gets.” W. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} ASTON says:— “I have the ‘JACKALL’ system on my Talbot saloon. I would never willingly have a car without it. In my opinion, your hydraulic jacks are the greatest contribution to motoring convenience since the introduction of the self-starter. It cannot be long before every car with pretensions of being up to date is fitted with these time and trouble-saving jacks.” [Logo Text]: JACKALL EST. 1928 | ||
