Working Steam Roller Model Pulls Two Persons On Cart
STANDING only ten and three-quarter inches high with an overall length of 20 inches, a working scale-model of a steam roller constructed by C. Hollandtrick, of Lincolnshire, England, is claimed to be powerful enough to haul a small trolley seating two persons. The model weighs 26 pounds and was constructed at a cost less than five dollars. A coal fire being impractical on such a small model, the water is heated by means
of a paraffin burner to create a steam pressure of approximately 40-45 pounds per square inch in the broiler.
Novel Cigarette Automat
YOU probably never saw a real live bird that looked like this one, but then you never saw a real live bird do what this one does. When you want a cigarette he bobs down and comes up with one in his beak, just like that. Unlike most trick cigarette boxes, this one won’t be discarded very soon because you and your friends will never get tired of having cigarettes handed to you in this novel manner.
Make Trailer From Defunct Auto
OLD automobile bodies that have been consigned to the junkyard can still do a lot of good in the world, for they can be pressed into service as very substantial trailers.
The chief operation you will have to perform on the auto is the cutting ofF of the front at about the point of the dashboard. This disposes of the motor and its weight. You can easily contrive your own coupling. In the photo above the side members of the chassis are bent in, to form a V, at the point of which is attached the coupler.
Of course, weight should be reduced to a minimum. Strip the machine down to its essentials, and you’ll have accommodations for extra passengers and luggage when you go camping.
Runners Convert Wagon
Four small wheel runners quickly convert this child’s wagon into a steerable sled for use in winter. Patented by Emil Lersch, of Pensacola, Fla., the ski-like, turned-up metal runners are each clamped firmly to a wheel of the wagon by a pair of side plates shaped to conform closely to the wheel’s contours. In addition, angled braces between the runners and the axles provide lateral stability.
This Sidewalk Runabout is Easy to Build
By Hi Sibley
THERE is one definite rule to follow in making a sidewalk automobileâ€”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.
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.

You Can Learn Glass Blowing
THE reason that amateur glass blowing is such an interesting hobby is that the work acts as a stimulant to your creative ability. With very simple and inexpensive tools, in a corner of a room or in the attic or basement, you can quickly learn to make dozens of useful and ornamental pieces such as vases, small glasses of different shapes, beverage sippers and other articles of that nature. With further practice and experience you will not find it difficult to make the tiny animal, bird and flower novelties or “whatnots,” which are so popular in the home, and know that the design is original and that a similar article cannot be purchased in the stores.
From brazen helmet and warrior’s shield of the ancient world to the modern flashlight cell and galvan-ized steel plate, zinc has worked in the service of man.
By KENNETH M. SWEZEY
THOUGH it seldom makes headlines, humble zinc ranks with iron, copper, and lead as one of the most widely used metals in the world. Hundreds of thousands of tons of zinc are used annually as a molten dip to coat iron and steel pipes, tanks, and roofing for protection against corrosion. The process is known as galvanizing.
Brass is made of about 30 percent zinc and 70 percent copper. Granular zinc and zinc dust are used in the laboratory to release hydrogen from acids, to recover gold and silver from solutions, and in organic synthesis. More than 500,000,000 zinc cases for use in electrical dry cells are manufactured every year.
Model-Airplane Motor Drives Scooter
Up to 230 miles on a gallon of gasoline is the economical fuel-consumption rate of a curious motorized scooter constructed by E. Roberts, of Philadelphia, Pa. Converted from a toy motor cycle, the midget vehicle is driven by a one-fifth-horsepower model-airplane engine, acting on the front rubber-tired wheel through a spring-supported friction roller. Fifteen miles an hour is top speed on level ground.
