WHEN THE TIRE DEFLATES THE BELL RINGS. 



All the experts on tires insist, in season and out of season, 

 that the one chief cause of tire degeneracy is deflation, and that 

 if the motorist would keep his eye constantly on the tire to 

 see that it is properly inflated his troubles would be greatly 

 decreased. A certain inventive genius has come to the assistance 

 of the motorist with a device that renders it unnecessary for 

 him to keep his eye constantly on the tire, as this will do the 

 •work for him. It is a small piece of metal in the shape of a 

 "U" and goes over the tire, having two plungers which drop 

 past the rim. When the tire is entirely inflated nothing happens, 

 hut when the air begins to escape and the tire to go a trifle flat 

 these two plungers are driven up a little further past the rim 

 and strike a bell. The motorist then knows it's time to insert 

 more air. 



■ I ■ HERE is no place in the world where it is so essential to stop 

 *• a fire as on shipboard, as it is a case of conquering the fire 

 or going down. Every precaution is taken against the spread of 

 incipient blazes. Among these precautions is the use of the fire- 

 fighting apparatus shown in the accompanying sketch, which con-

sists of a smoke helmet attached to a rubber tube at the other 

 end of which there is a fresh air bellows. When it is necessary 

 for one of the crew to take the nozzle of the water hose into a 

 compartment dense with smoke, where breathing would be im- 

 possible or exceedingly difficult, he has only to adjust .this smoke 

 helmet to his head, while a comrade outside works the bellows 

 and keeps him supplied with an abundance of fresli air. 



WATER PAILS OUT OF OLD INNER TUBES. 



A contributor to the "Automobile Trade Journal," who has 

 an inventive turn of mind, makes the following suggestion for 

 utilizing old inner tubes as collapsible water pails : 



"Altho collapsible water pails can now be purchased very 

 cheaply, it is well to know how easily a useful one can be made 

 w'ithout any expense. If three or four feet of good rubber is 

 selected from an old inner tube a water pail of the desired 

 length can be made by cutting oflf a portion of the tube and 

 cementing one end under pressure so that it is closed water- 

 tight. Such an article as this can be carried in almost any 

 part of the car, and may prove very useful in filling a radiator 

 from a roadside stream."
