Show AUTO JACK THAT WORKS QUICKLY Prolongs Life of Tires by Taking Off Heavy Load While Car Is in Garage. CONSTRUCTION VERY SIMPLE Once Made and Put to Use Set Will More Than Pay for Themselves in Few Months Illustration Shows Operation. It is possible to prolong the life of automobile tires if the car is jacked up as often as possible when not in use. During the night, and at other times when the car is in the garage, which usually represents more than half of the time, the car might just as well be raised from the floor, saving sav-ing that much weight on the tires. Extra load is not only removed from the tires, but any tendency toward to-ward flattening of the shoe and making mak-ing its wearing qualities uneven is lessened considerably. Pay for Themselves. A set of home-made jacks will not take long to make, and once made and put to use, will much more than pay for themselves in a few months. The construction of the jacks is simple. A six-foot length of strap iron three-fourths inch in thickness and one inch wide is required for each jack. This is bent nearly double in the center, and each end provided with a right-angle turn and four inches turned to slightly more than right angles with the length of the jack.

This is then bored for a one-quarter-inch bolt an inch from the other end and holes to match drilled through each side of the jack at a height which will place the bottom of the notch on a level with a point about the center of the wheel-hub. How Jack Is Used. The illustration shows how the jack is used. The first position shows the feet of the jack placed tight against the tire with the notch of the wood block against the undo side of the wheel. When the top of the jack is pushed in toward the wheel, the action ac-tion raises the wheel about two Inches and transfers the weight from the tire to the hub. The feet afford suflicient hearing to enable the car to stand rigidly when four jacks have been applied and remove all possibility of its shifting to one side and back to (he floor.
