This Sidewalk Runabout is Easy to Build

By Hi Sibley

THERE is one definite rule to follow in making a sidewalk automobile—get your engine first and build the car around it. This applies pretty much to the wheels, too.

A half-horsepower, two-cycle washing machine engine is available in nearly all sections of the country, and as these can be had second-hand at a reasonable price and have sufficient power for moderate speeds, they make satisfactory installations. Herewith are working drawings of the little car owned by Richard Weber, of San Marino, California, which is driven by this type of motor and has proved successful for a long period. It is very easy to build.

Uranium For Sale

A-metal goes on market, and other odd metals find new uses as they step out of chemistry boohs into everyday living.

By Alden P. Armagnac

WANT to buy some uranium? You can, now, for the A-metal’s on the market. Just explain to the New York licensing division of the U. S. Atomic Energy Commission what you want it for, satisfy them that you’re a reputable researcher, and you’ll get a license entitling you to send in an order.

To meet legitimate needs, the AEC has authorized the sale of 200 pounds of uranium through normal commercial chemical channels. That’s news, because in recent years every available ounce of the silvery metal has been earmarked as a source of fissionable material for A-bombs and chain-reacting piles.

New Weapons for the Next War

by JAY EARLE MILLER

The last war saw the development of tanks, flame throwers, poison gases and airplanes as war weapons—what will the next war bring forth? Little-known facts about the latest death-dealing weapons and the defenses developed to draw their fangs are set forth by Mr. Miller in this absorbing and authoritative article.

A GERMAN patrol of Uhlans, the sunlight glinting on their polished helmets and the tips of their long lances, rode out of the woods above the Marne and down toward a small copse where a scouting detachment of Algerian cavalry, with drawn sabres, laid in wait for them.

The time is mid-August, 1914, just seventeen years ago, and the description is from a recently published volume of war memoirs by a French cavalry officer. Imagine the scene—lances against sabers. Here’s another war-volume, “Fighting Fury”, the autobiography of Major James Mc-Cudden, V. C, the famous “Jimmy” McCudden of the British Royal Air Force, who shot down fifty-seven German machines before he lost his life in an accident. Just seventeen years ago today (August 22, 1914) he, with the British air force in France, saw his first German machine. The ground crew turned out to take pot shots at it with rifles while six English planes took off, armed with home-made hand grenades, in an effort to bomb it down.

Keep Photo of Deceased on Grave

PORTRAITS on tombstones are a decorative idea that is being put into practice throughout the country.

Consult the photo below to see how the idea is worked. A photo medallion of the deceased is cut out and inserted in a frame carved in the headpiece. The photo is then inserted and cemented in place.

A window of heavy isinglass, cemented, with a good grade of transparent waterproof glue, will preserve the photo for years and years against the ravages of time and weather, making a lasting memento to the one whose grave is so marked.

Four Novel Toys You Can Make With Rubber Balloons

These drawings show the construction of four novel toys made from circus balloons that will prove highly fascinating. Fill the balloon with hydrogen and attach to it a postcard bearing your name, and a request to return it from whatever point it falls to earth. Thus you can learn in what direction and how far it travels. Another balloon, equipped with a gondola will float in the air like a wartime captive dirigible. The aerial torpedo which zips up through the air is made by affixing fins to an air-filled balloon. The unique air boat cuts through the water under power of air exhaust from blown up balloon.

A phantom herd… from deep down underground

Not long ago the primary source of glycerine was herds of cattle! Fats from these animals were transformed, by the makers of soap, into glycerine.

Gliding unseen through underground pipelines to the refinery and then the chemical plant, petroleum has become the partner of cattle herds. From the products of petroleum, Shell Chemical has been making high-quality glycerine since 1948.

Today, Shell glycerine fills about one-third of
America’s needs. It goes into ink, explosives, lipstick … cellophane and tobacco … toothpaste, paint, even sausage casings. It’s used in more than 1500 different ways … in just about every industry.

Manufacture of glycerine from the products of petroleum is another Shell Chemical contribution to the nation’s industry.

THE KID WITH THE KAISER CONTRACT

by Dean Jennings

Stanley Hiller, teen-age tycoon, casually sat down in his workshop and built the co-axial flying machine Da Vinci dreamed about.

WAY back in the florid days of the Renaissance, when painters were social heroes and scientists were frequently hauled off to the clinic for nitwits, the great painter Leonardo Da Vinci invented a flying machine— on paper.

It would have two motors, one above the fuselage, one below, with long horizontal rotor blades revolving in opposite directions. This curious gadget was the father of all helicopters. But Da Vinci’s friends said he was as nutty as a squirrel, assuming they had squirrels in those days, and the idea never got beyond the drawing board.
