If a man has a nickel he can drop it in the hopper and immediately pass to his train without losing time buying tickets.

Loosening all the Lugs of a De- mountable Rim at Once

F you own an automobile you know just what it means to have a tire puncture. You have to unbolt each clamping lug in order to remove the rim and then adjust and tighten each into position when the rim is replaced. If you" have six bolts to unscrew and then tighten, each one takes you about two minutes — a total of twelve minutes. What a saving and a blessing it would be if all the clamping lugs could be released at once and clamped back into position at once.

Mr. R. G. Mason, a Brooklyn in- ventor, has made this possible and thus you can change your tire in almost no time at all. He mounts a heavy locking ring outside or in front of the clamping lugs on the side of the wheel felly. This ring has openings corresponding with the lugs, and by moving the ring the detachable part of the rim can be taken off and put on in one operation. Turn the ring until the openings are op- posite the lugs; the rim can be removed because the lugs are loosened. Now when the lugs are to l)e readjusted and locked into position, the ring is shifted again until the solid portions of it are opposite the lugs. The illustration shows the details.
