FOOD FOR THE GERMAN FIGHTING MEN Loads of produce are gathered in Cologne, Germany, for shipment into East Prussia. On the outposts along the Arras there have been exciting engagements in which the soldiers of both sides have dis tinguished themselves. Here the French have thrown back a party of Germans. Not so long ago men of this race were cannibals, very fond of long pig" as they termed the flesh of man, but they are thoroughly tamed and strong Christians now. THE MEN THAT THE TURKS ARE MEETING IN NORTH AFRICA Trained Englishmen of Egypt lead the troops in the defense of England's possessions along the Mediterranean.

(First Prize, Ten Dollars) KEEP THE TANK FROM AGREAT many water tanks are ruined each winter A AIR weights on the outside of the tank. Attach a weight to the bucket to hold it THE WEIGHTS A AND B HOLD THE INVERTED down. When the water freezes, the pressure that would be against the walls acts on the air in the bucket, compressing it. The size of the bucket should be in proportion to about one gallon to the barrel. The amount of air that is then confined beneath the surface of the water I will be able to take up the expansion of the water in the tank as it freezes. Charles Kimmel, Dayton, Ohio. (Third Prize, Two Dollars) SAFETY HOOD FOR BEVEL GEARS THE bevel gear has claimed the fingers of more mechanics than any shop device that necessarily possesses dangerous and rapidly moving parts. Experienced machinists are, however, injured more often through a lack of knowledge of the location of these parts than by any personal carelessness or oversight. The inexperienced man has been the greatest victim, for he does not realize the powerful drawing tendency of the gears if clothing once enters the mesh of the teeth. (Third Prize, Two Dollars) MOTORCYCLE MAKES A MILKCART FOR the price of a good horse, $370, an Indiana milkman purchased a motor cycle and side car, and now he makes his rounds in half the time required by horses, and his speedometer shows a thirty-five-mile-a-day average. Every evening he has to travel nine miles to get home and now he makes it in thirty minutes, although in the days of horse travel he used two and a half hours. On days when the motorcycle is not in use for carrying the milk cans about the country, it hauls other products from the farm and brings back freight, express packages, and other things from town. A special box makes the little machine into a carrier for calves that are not over two months of age and for small pigs. EQUIPPED WITH SAFETY HOOD, GEARS DO NOT INJURE WORKMEN The photograph illustrates a simple protection hood which can always be applied in some manner to these gears, no matter how they are assembled to perform their part in the operation of the machine. The hood can be so shaped and bent as to lend a pleasing appearance to the eye, and a few tap bolts small in size will anchor the supports to the machine body. Not only will this simple and inexpensive home-made hood protect the workman, but it will also protect the gears, which are so often ruined by some hard substance accidentally dropping into the gear mesh. This device was applied by a mechanic in a large machine shop when the company put through a "safety first" campaign. It proved to be very efficient, was cheap, and not only aided the campaign, but also protected the machine itself. F. W. Bentley, Jr... C. A. Kuntz, Bremen, Indiana. MILK VAN FOR DELIVERIES |
