This armor is not stiff or hard, and an additional ad-vantage claimed for it is that it takes up an important amountof strain or jar, thus protecting the air tube against the injuryto which this feature of most pneumatic tires is subject. Thenew tire has been applied to bicycles, wagons, and automobiles,including one vehicle weighing 3000 pounds, with satisfactoryresults. The specially prepared fabric used in the tires is alsooffered for use in filling horse collars, bicycle saddles, and rub-ber heels, as well as a substitute for felt.
