Personalized Laundry Bag for Child’s Room
Topped with a portrait of its little owner, this child’s laundry bag looks much like a life-size doll, and its novelty will go far to encourage children to take care of their soiled clothing. A good close-up snapshot of the child is selected and that portion of the negative showing only the head and possibly part of the shoulders is enlarged as close to 8 x 10 in. as possible.
GIVE CHILDREN ENDLESS FUN AT HOME
By Morton Bartlett
UNIQUE comic-strip “talkies” can be given in your own home at trifling cost. The pictures are thrown upon a screen by means of a simply made magic lantern, and the children speak the lines of the various characters through a home microphone connected to an ordinary radio receiving set.
The materials are listed on page 85. The first step is to make the lantern. Its width is equal to the focal length of the magnifying glass which will be the lens. Determine this by tacking a piece of paper against the wall 10 ft. from a lighted lamp. Hold a ruler perpendicular to the paper, and run the lens, perpendicular to the ruler, along the inch marks. At some point a clear image of the lamp will be seen on the paper. The focal length may now be read from the ruler. This distance is the dimension YM in the drawings. Having found this basic dimension, cut ten pieces of wood as specified in the list.
Puppets Made from Light Bulbs
ELECTRIC-LIGHT bulbs and radio tubes form the basic materials with which Alfred Wronkow, of New York City, fashions the amusing caricature figures shown above. For the “social-light” wedding scene pictured, Wronkow used common household items to dress the principals and attendants at the fusing of “Claire Coppertop,” a dainty twenty-five-watt bride, and “John Glasstum-my,” her husky seventy-five-watt groom.
A One-Man Show with a Magic Hat
IMPERSONATING different characters by appearing in a succession of hats is a trick well-known to the stage comedian and one that you can easily perform in your home with the aid of the simple ring of felt shown here. By folding and twisting it, the wearer transforms himself successively into a general, a president, a clown, and as many other personages as ingenuity may suggest. Make the ring of heavy hat felt if procurable; otherwise, have two thicknesses of the lighter grade, that every dry-goods store sells, stitched together on a sewing machine. A mirror behind a screen will help you to adjust your hat carefully but speedily for each impersonation. To aid in learning the shapes, the indicated letters may be chalked on the ring. At the end of entertainment, pull the ring down around your neck and say, “Myself.”
Magnesium the BANTAMWEIGHT METAL
How Chemists Have Put It to Work as a Jack-of-All-Trades.
By KENNETH M. SWEZEY
DURING the war magnesium was extensively used as a lightweight structural metal for aircraft parts and as pyrotechnic material for star shells, signal flares, tracer bullets, and flash and incendiary bombs. Strong, silvery white, and only two thirds as heavy as aluminum, it is the lightest of all construction metals. In the form of powder, thin sheets, or wire, it burns with a dazzling flame that water or even carbon dioxide will not put out. Never found alone in nature, magnesium is made on a tremendous scale by the electrolysis of its compounds. These compounds are among the most plentiful substances in the crust of the earth. Whole mountain ranges consist of dolomite, a double carbonate of magnesium and calcium. Asbestos, talc, and meerschaum are magnesium silicates. Epsom salts, named after the springs at Epsom, England, where they were first isolated in 1695, are magnesium sulphate. In the form of its chloride, there are nearly 6,000,000 tons of magnesium in every cubic mile of-the sea, a vast storehouse of supply.
Motor Unit Runs Bike or Mower
Powered by a 1-1/2-hp. engine, a two-wheeled unit designed and built by William Lusk of Cicero, Ill., can be readily attached to a bicycle, lawn mower, or scooter. Small pneumatic wheels carry its 200-lb. weight without marking soft turf and give ample traction for cutting heavy grass. Used on the highway as a scooter or bike motor, the unit delivers better than 25 m.p.h.
Lusk used a 1/8″ steel plate as a combined platform and chassis. The axle is a 5/8″ steel shaft running in ball bearings, with a small over-riding clutch at each wheel to give differential action. Power is transmitted by a pair of V-belts from the engine to a 7-to-l gearbox taken from a washing machine. A movable idler acts as the main clutch. By using V-belt pulleys of different diameters, Lusk changes the effective gear ratio to suit the job the unit is doing.
Retired Sailor Builds Cars For Handicapped Veterans
Using surplus airplane parts almost exclusively, a retired Navy chief petty officer builds oversize motor scooters for handicapped veterans. Also built into the compact vehicle are small power tools such as a jeweler’s lathe, a key-duplicating machine, a knife-sharpening outfit and a shoe-repair kit so the veteran can earn his living right inside his car. The retired sailor, Edward T. Adkins of Watsonville, Calif., started to build the first vehicle, which he calls the “Vetmobile,” while a patient at a Navy hospital. He did it to get a fellow patient, a discouraged amputee, “interested in something.” The tiny cars are made of a drop tank split lengthwise and mounted on a strengthened motor-scooter chassis. A converted auxiliary starter-motor generator from a B-29 powers the machine. One Vetmobile built for a Dallas, Tex., amputee is equipped with a two-way radio.
ELECTROMAGNET Drives VIBRATING JIG SAW
ONE of the most useful of all power tools for the home workshop, yet perhaps the easiest to make, is the vibrator type electric jig saw. You may use such a saw to cut intricate patterns in wood as thick as 1/2-inch, or as thin as 1/16-inch. The great speed at which the saw travels provides smooth and accurate cuts. With no rotating parts, a jig saw of this type should last indefinitely.
An electro-magnet attracts and releases a metal diaphragm to which is attached a saw blade. A flat steel spring supports and gives necessary tension to the upper end of the saw blade. With the unit adjusted properly, the stroke will be about 5/8-inch.
The speed of this saw depends upon the frequency of the A. C. power used, as the magnet is energized and de-energized twice for each cycle. Thus there will be 120 strokes per second when 60 cycle power is used for the electro-magnet.
Hydraulic Wheel-Chair Support
Anyone confined to a wheel chair will find use for this support, whether in the home or in business, as it permits the occupant to raise, lower, or turn the chair to any angle
By Clinton R. Hull
SPECIFICALLY DESIGNED to hold the wheel chair of a handicapped filing clerk who uses a two-shelf, circular desk in his work, this swivel support is mounted on the hydraulically controlled column of an old barber chair. The latter not only permits a swivel action, but its hydraulic mechanism allows the wheel chair to be raised by its occupant to any height within the limits of the barber-chair columnâ€”in this case to permit the occupant to work from either level of the desk. It also positions the chair at a height most convenient for using a typewriter which is fitted on a swivel bracket mounted on the end support of the circular-desk shelf.
