“Tourist” Trailer for Youngsters Is Towed by a Tricycle (Oct, 1938)

For some reason this reminds me of a David Lynch film…

“Tourist” Trailer for Youngsters Is Towed by a Tricycle
Touring the seashore at Venice, Calif., is a streamline trailer towed by a streamline tricycle. Tiny as it is, the miniature trailer is big enough for two little girls to “keep house” in as they play on the beach. Their grandfather built the two-wheel trailer.

X-Ray Tells if You’re Grand Opera Star (Sep, 1932)

X-Ray Tells if You’re Grand Opera Star

IS THE time drawing near when science will be able to devise an almost mathematical formula for making great singers out of any aspirant to musical fame? Is there any way to determine the precise physiological differences in vocal organs and other parts of the body which might account for good, bad and indifferent singing voices?

An attempt at answering the questions is being made by scientists, who have made X-ray exposures, during the actual act of singing, of the throats and heads of such famous opera stars as Lawrence Tibbet, Benjamin Gigli, Reinold Werrenrath, and others of vocal fame.

Tour of a Very Early TV Station (Nov, 1931)

Operating a TV station using electro-mechanical equipment looks really hard. That camera looking thingy at the bottom of the page is not in fact a camera, but an arc lamp. In front of the lamp is a spinning disc with holes punched in it which scans the light across the subject. The “camera” is actually composed of those six light-bulb looking things in front of the subject. They are just ordinary photo-electric cells.

And to view it at home? Here’s what you need:

“you will require a 60-hole scanning disc, revolving at 1200 revolutions a minute, giving 20 frames a second. Further, you will need two short-wave receivers, if you desire to pick up both image and voice frequencies. The images are transmitted on 107 meters, and the sound is sent out from W2XE’s shortwave transmitter on 49 meters.”

Latest Television Broadcast Station

CHICAGO, Toronto, Boston and Washington have recently reported the regular reception of both “sight” and “sound” signals from the new Columbia television station W2XAB, and its accompanying sound transmitter W2XE. The Columbia “telecasting” station was opened on July 21 last, when the Hon. James J. Walker, mayor of New York City, lifted the curtain from the photo-electric cells; which formally marked the opening of the station. The television transmitting apparatus and antenna systems are adjacent to the studio, which is located on the 23rd floor of the Columbia Building at 485 Madison

Checkers for the Invalid (Aug, 1951)

Checkers for the Invalid

Checkers or chess can be played by invalids and blind persons with slotted boards that hold the pieces in place. Each square is numbered with raised numerals so the blind can identify them. The black pieces have one flattened side for identification by touch. The key slots hold the pieces in place even though the board is tilted as it would have to be when used by many bedridden persons.

Ad: Erector Set (Dec, 1935)


Hello Boys!
Look at that giant power plant! You build it yourself with the great new Erector. Piece by piece you erect its massive steel frame. Assemble its enormous fly whee1—pistons—governor. Mount its big, shining boilers. Then you hook up the powerful Erector electric engine and it throbs with action.

Sensational THRILL RIDES Invented for N.Y. World Fair (Apr, 1939)

“one smart inventor has devised a ship that takes passengers to Venus, which is part of the way to the moon”
Wow, I had no idea Venus was so close!

And don’t forget: “These are no sissy rides, and if it’s a thrill you want, you’ll get it at the New York World’s Fair!”

Sensational THRILL RIDES Invented for N.Y. World Fair

HOW would you like to experience the thrill of a parachute jump— without the accompanying dangers of the ‘chute failing to open, of being blown out to sea or of landing in a tree? Well, that thrill will be yours if you are one of the lucky 60,000,000 expected to visit the New York World’s Fair after it opens on April 30. As a matter of fact, a safe parachute jump will be only one of the many sensations ingenious engineers have invented for the Fair visitor’s amusement. If the ‘chute jump seems tame, try the aerial ship which the rider can pilot himself. It’s safe, of course, because a cable keeps the ship anchored to a revolving pole, but you can turn or stall in a steep climb or experience the sensation of a power dive, if you are up to it.

First Surround Sound – 1934 (Apr, 1934)

And it only took us another 50 years or so before it became commonplace.


“Three-Dimensional” Sounds Created

LIKE pictures on a screen, the best of public-address amplification and loudspeaker reproduction hitherto available has lacked reality. It is not that the instruments are defective in their reproduction of pitch and volume; but the ear is a fairly selective instrument, and hard to deceive when aided by the eyes. The sounds are right, but the directions from which they come are wrong. However, a recent demonstration, staged by telephone engineers, has the astonishing effect of overpowering the testimony of the eyes. Unseen players, singers and dancers seem to move tunefully or noisily across an empty stage.

Inventors Turn to Toys (Dec, 1928)

I particularly like the cow on the second page. You can fill it up with milk and um… milk it.

Inventors Turn to Toys


This locomotive is made for the boy who likes to build his own, for it comes “knocked down” packed in a box. It is assembled or taken apart by following instructions; and parts may be replaced. — Dorfan Co., Newark, New Jersey

Water Wings (Oct, 1931)

Inflated Arm Bands Cut Hazards of Swimming Lessons
THE hazards and effort involved in learning to swim are greatly reduced by means of the novel inflated arm bands, or “side wings,” recently introduced at Los Angeles beaches. Wearing these wings, the novice can venture into deep water without fear and can rest when exhausted.

When pumped up with air, the wings, which are made of rubber and fitted on the arms near the shoulders, enable the swimmer to keep his head above water while he perfects his strokes, thus simplifying the ordeal considerably.

Each arm band is provided with valves for inflation. When blown up the wings are extremely light and in no way interfere with circulation of the blood.

Machine Shows Cartoons Without Screen (Sep, 1932)

Machine Shows Cartoons Without Screen
A NEW idea in motion pictures machines has just been developed. by Max Fleischer, the well-known movie cartoonist. The mechanism, shown above, consists of a large cylinder on which are attached cartoons of the various comic characters, and a large rotating shutter with two narrow slits on either side of it.

As the cylinder is rotated, the shutter revolves in unison, so that by standing at a point in front of the machine and looking at the right portion of the shutter, animated cartoons of amazingly smooth action can be viewed.

In contradistinction to the common movie projector, Mr. Fleischer’s machine has no intermittent action, and the big wheel never stops but revolves continuously. A full picture with smooth flickerless action is the result.
