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.
SEE WHAT MIGHTY MECHANICAL MARVELS YOU CAN BUILD WITH THE GREAT NEW
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 whee1â€”pistonsâ€”governor. Mount its big, shining boilers. Then you hook up the powerful Erector electric engine and it throbs with action.
“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!
Sensational THRILL RIDES Invented for N.Y. World Fair
HOW would you like to experience the thrill of a parachute jumpâ€” 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.
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. â€” Dorfan Co., Newark, New Jersey
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.
Spring-Driven Boat Model
RIVER boats, with the paddle wheel at the stern, are well known in many localities. A simple little model, which will run fast, can be made as shown, from a board.
A, 18″ by 6″ by 1/2″ thick (although any size may be used) with a 3″ by 4″ notch cut in one end for the paddle wheel, and the other end tapered as shown.
The paddle wheel’, B, consists of two bent L shaped pieces of tin soldered to a 1/8″ metal shaft. The shaft is placed in screw eye bearings. To hold the front of the boat down the lead weight D, may be used.
Two stiff steel springs, C, with strings, E, attached to the free ends, are mounted on the board. The other ends of the strings are securely attached to the shaft. Wind up the wheel and the boat is ready to go.
Bridge Played Via Short Waves
CONDUCTING a bridge match in which the opponents were 6,000 miles away sounds incredible, but the Culbertsons engaged in just such a game. Using two official “dummies” who made the plays called for by the players located at Buenos Aires Mr. and Mrs. Culbertson engaged in the International Contract Bridge match although they were in New York.
At Buenos Aires an announcer named the plays made by the South American players. The “dummies” at New York followed these just as though they were opposing the Culbertsons, themselves. At the other end “dummies” representing the Culbertsons made the plays announced over the air.
New Power For Mechanical Toys Opens Large Field For Alert Inventive Minds
COUNTLESS inventors have rolled up tremendous fortunes by the development of new and simple toys as the several hundred manufacturers in this industry are ever in need of fresh attractions. Indeed, at the present time, there is an urgent cry for new material, and consequently we shall devote this month’s department to an outline of some of the more pressing problems. Toys can be developed by any man without an elaborate work shop since most of them are made of bits of wood and cardboard. Some of the biggest money makers on record have been perfected with little more than a jack knife.
FOR new Hallowe’en thrills, put on a mediumistic party with turban-bedecked medium, darkened room, spirit writing, tables floating in the air, and all the other tricks which fake spirit mediums use so successfully. The mere suggestion, on your invitations, that all weak-hearted persons should stay at home will insure a crowd.

ANT PALACES Create NEW Pastime
THOUGH it sounds like something out of “Alice in Wonderland,” the ant palace is a very real contrivance that sells for five dollars, and sells very rapidly at that. Strange things have been built in the name of entertainment, but seldom anything quite as novel and ingenious as these glazed-in ant apartments with both northern and southern exposure.
