Are you Driving a Pleasure Car or Death Trap?

One in every three U. S. cars needs brake adjustments. One in every nine is a potential killer. This story gives the lowdown on the menace of bad brakes and tells you how to avert accidents.

by CARL D. WEBB

TWO men in a heavy touring car were roaring down the Jack Rabbit trail in California. Faster and faster they sped as the dark night and the deserted road lulled the driver into a false sense of security. Suddenly, as he rounded a curve, he saw a dark shape ahead. Frantically he jammed on his brakes and jerked the steering wheel. A wailing scream from the tearing tires— then a terrific crash as the skidding car smashed broadside into the obstruction. The two men in the touring car probably did not live long enough to feel the searing heat of the flames which enveloped their car and the gasoline truck which they had hit.

JETS LOOK FOR JOBS

WHAT we want,” the public-utilities official stated, “is an auxiliary engine that will help our construction trucks and trailers climb up into the mountains. The loaded vehicles weigh 33 tons and right now we grind along at six miles per hour. We want to get up those grades at 45 miles per hour.”

The Aerojet engineer thumbed his slide rule for a moment and grinned.

“We have just the thing,” he commented. “Five hundred horsepower in a package 18 inches square. How’s that? Turn the auxiliary power on at the foot of the grade and cruise along as fast as you want. Only trouble is, you can’t afford it. At $2.50 per gallon, fuel will cost about $1200 per trip.”

That wide tank on the left looks like it would break in half at the slightest bump and it looks like that truck on the left would have a pretty hard time pulling that huge armored trailer.

Inventors Offer Thousands of Ideas to Help Beat the Axis

WAR inventions are flooding the National Inventors Council and the U. S. Patent Office. At the Council’s headquarters in Washington, D. C, 45,000 suggestions have been received during the last year. And 3,000 of them have been adopted—one out of 15, an amazingly high proportion that pays tribute to American inventive ability. Results have well justified the effort of sorting valuable new ideas from equally well-meant schemes that prove unsuitable for various reasons.

Have Fun With This Chariot-Type Tricycle Trailer

Rolling along on semipneumatic wheels, this little trailer will double the enjoyment the youngsters get from their tricycles. The frame, rail and tongue are all bent from thin-wall conduit, either by using a standard pipe bender or by filling the conduit with sand, plugging the ends and then bending by hand. The trailer-hitch bolt engages a hole drilled in a piece of flat iron which is bolted to the tricycle-seat frame. The wheels are fastened with cotter pins or the axle is drilled and tapped for attaching them with roundheaded screws

The headline double meaning had to be intentional, right?

How to handle your car when you’re loaded

There are times when even the best suspension system can’t cope with your car’s rear-end sag.

When you tow a recreational vehicle. Or a horse trailer. Or a boat. Or a snow-mobile. Or any off-road vehicle.
When you overload the rear end of your car, or wagon, or pick-up-truck—with people, luggage, tools, samples or equipment.

The sensational new Scovill Load-Tamer works with your air shocks to keep your car on the level. No more sag. No more drag. You accelerate better, corner better, steer better. Your headlights aim properly. Your tires wear better. In short, you get a safe, reliable, comfortable ride.

Legless Man Tours in Odd Trailer

Traveling alone in a unique, powered trailer, Freddie Carson, a legless newsboy of Santa Ana, Calif., is making a 2,500-mile-trip across the continent to Florida. Hitched behind a three-wheel invalid chair, as shown in the photograph, the trailer is equipped with a one-horsepower motor that provides a top speed of thirty miles an hour. Remote-control levers operate the engine from the seat of the chair. Although the motorized trailer is only seven feet long and four feet wide, it is equipped with running water, a bed, a radio, and other accessories. On his transcontinental trip, Carson expects to get more than 100 miles to a gallon of fuel.

MIDGET TRAILERS
Here are two simple designs of midget trailers that can be towed by foot-operated juvenile autos or carts. The one at the right is exceptionally easy to build. Sides, seat and floor are plywood while the front and back may be sheet metal. With circular holes in the sides, and the latter cut to a pleasing contour as shown, the thing has a decided streamline effect. Still, there’s no top and the rider seems to project through the roof. For the more advanced young “trailerites” the “covered wagon,” shown below, may be preferred as it more closely simulates the real thing in that it has a roof and a hinged door through which riders have access to the inferior. This one, also, is built mostly of plywood on suitable framing. In both cases a pair of coaster-wagon wheels, preferably of the pneumatic-tire type, are used for comfortable riding

Cyclist Takes Bed Along in Homemade Trailer

TOWING his sleeping quarters behind him in a compact trailer, an eighteen-year-old cyclist of Menominee, Mich., recently traveled nearly 1,200 miles to Boston, Mass., economically and comfortably. Post cards that he sold to curious spectators paid for his supplies during the fourteen-day journey. Streamline in shape, the sturdy trailer is a homemade product of his own design. He is shown above demonstrating his sleeping quarters to an admiring hotel doorman.

Trailer Chapel Has Speaker System

Built into a trailer, a chapel on wheels brings church services to isolated mountain sections of Virginia and West Virginia. Its rear wall unfolds to form a platform before the altar, and a canopy containing two loudspeakers for a public-address system, which carries the preacher’s voice to the congregation. A gasoline-driven generator mounted in the back of the sedan that draws the trailer supplies electric power for the public-address system and for cooking and lighting. Supplemented by a storage battery, the generator unit automatically starts when a light or appliance is turned on, and stops when all are switched off.

Inside the Biggest Man-made Brain

Navy’s new calculator has steel bones, silver nerves, paper impulses, and can make mistakes.

By Stephen L. Freeland

THE LARGEST brain in the world today is a mammoth electrical mathematician being built at Harvard’s Computation Laboratory for the U. S. Navy Proving Grounds at Dahlgren, Va. But its reign as king of the robots will be brief.

Work already has begun on faster, better calculators based on the lessons learned in creating this machine, known as the Dahlgren Calculator, or Mark II, just as this one was designed to be the big, tough brother of Mark I, which was built for Harvard during the war by the International Business Machines Corp. (PSM, Oct. ‘44, p. 86). Mark II, however, will not be retired. Even Mark I has many years of useful labor ahead. There is plenty of work waiting for all the big calculators now in existence and on the drawing boards. Mark I is still churning out answers to abstruse mathematical problems 24 hours a day, and Mark II will be taken to Virginia next month to begin an equally strenuous career.

The census department had some serious technical chops in 1950. Census workers were given maps and aerial photos of their districts so they could find all of the residences. The punch card counting machines seem pretty advanced as well with data validation circuits that would reject, for example, a two year old with six kids. I wonder how many kids they considered it alright for a two year old to have?

COUNT OFF, AMERICANS…

By Richard F. Dempewolff

For A house-to-house canvass that will make all the brush salesmen in the world look like an army of pikers, wait until you see the one that gets under way April first. Yup, it’s time for the 1950 decennial census, Uncle Sam’s national inventory of noses—the biggest quiz show, most mammoth tabulating phenomenon and most accurate poll in history.

It’s a job that has taxed the ingenuity of a harried Census Bureau every zero year since 1790. At that time 17 U. S. marshals and 600 assistants knocked on colonial doors, asked five questions of whoever answered, then tacked their lists on the walls of local taverns, so that people who’d been skipped could add their names or Xs when they dropped by for a flagon of ale. Results were mailed to the President.

New Comforts for Trailer Travel

ANY attractive spot along the road is home, for the owner of the latest in automobile trailers and fittings. Pictures on these pages show some of the most ingenious accomplishments of clever designers in providing new luxuries for those who live on wheels.

Vying to combine roominess with the most elaborate array of conveniences, trailer makers have performed magic space-saving feats. One offers a double-duty fireplace that heats the trailer by day, and turns into a dresser at night! Another provides a three-gallon hot water tank that swings out over a gasoline-stove burner to heat a supply for the washstand, shower, or kitchen sink, and disappears into a closet when it is not in use.
