High and Dry

In 1859, Irish priest Edward James Cordner reflected that most strandings of sailing vessels occurred on a lee shore; that is, the wind was blowing inland from the vessel’s location. This gave him an inspired idea: If the ship carried a selection of kites, these could be attached one to another and payed out until they sailed steadily over the land, and the line might then support a sort of gondola that could ferry crew and cargo to safety.

When a sufficient power of elevation and traction has been attained, a light boat of basketwork or other material, capable of containing one or more persons, is attached to the suspending rope of the last kite, more rope is then veered away and the light boat with its cargo will eventually reach the land without any chance of its being submerged in the sea, no matter how great may be the elevation of the waves.

It’s not known whether Cordner’s idea was ever adopted, but he does seem to have tried it out: In his 1894 Progress in Flying Machines, Octave Chanute reports that “it was tested by transporting a number of persons purposely assembled on a rock off the Irish coast, one at a time, through the air to the main land, quite above the waves, and it was claimed that the invention of thus superposing kites so as to obtain great tractive power was applicable to various other purposes, such as towing vessels, etc.”

The Wheel Cipher

http://commons.wikimedia.org/wiki/File:Jefferson%27s_disk_cipher.jpg

Thomas Jefferson, already absurdly accomplished by 1795, somehow found time to delve into cryptography, where he devised this cipher system. The letters of the alphabet are printed along the rim of each of 36 disks, which are stacked on an axle. One party rotates the disks until his message can be read along one of the 26 rows of letters, somewhat like a modern cylindrical bike lock. Now he can record the letters in any one of the other 25 rows and send that string safely to another party, who decodes it by reversing this procedure. If the message is intercepted, it’s useless even to someone who has the disks, because he must also know the order in which to stack them, and 36 disks can be stacked in 371,993,326,789,901,217,467,999,448,150,835, 200,000,000 different ways.

This is pretty robust. The cipher below, created in 1915 by U.S. Army cryptographer Joseph Mauborgne, has never been solved. “The known systems from this year (or earlier) shouldn’t be too hard to crack with modern attacks and technology,” writes NSA cryptologist Craig P. Bauer. “So, why don’t we have a plaintext yet? My best guess is that it used a cipher wheel” like Jefferson’s.

Through the Motions

https://www.google.com/patents/US563578

This “device for teaching swimming,” patented by James Emerson in 1896, teaches good technique mechanically. The teacher places the machine in a swimming pool or open water, the student climbs aboard, the teacher turns crank handle 13, and the machine guides the student through the motions of swimming, “these arm movements being so nearly like those performed by an actual swimmer that the beginner who has these movements mechanically imparted to her arms thereby shortly acquires the swimming arm stroke.” What could go wrong?

Moonlight Towers

When electricity became widely available in the late 19th century, some American cities put it to its fullest use: They replaced the moon.

Fitted with powerful carbon arc lamps, “moonlight towers” could illuminate a city’s streets “brightly enough to read a watch from as far away as 1,500 feet.” At first they were greeted as symbols of progress: A visitor declared the citizens of Aurora, Ill., to be “in a state of delighted enthusiasm over the splendid practical results,” and one Detroit resident reported that “the foliage is weird and beautiful. All places within the scope of light are bathed in the faint but fairy-like illumination of the moon in its first quarter.”

But in time residents found that simple streetlights provided better illumination and eliminated the disorienting shadows cast by an artificial moon. Most of the old installations have been dismantled, but 17 of the original 31 towers in Austin, Texas, are still in use — the 165-foot landmarks have stood since 1895, and have been listed since 1976 on the National Register of Historic Places.

Rising Above

This is rather unpleasant. In 1883 John Fleck patented a “life-saving apparatus for privy-vaults,” “to provide a means of escape from the vaults should a person by accident fall therein.”

Apparently this was a problem. “In various sections of the United States deep vaults are commonly used, generally constructed of masonry, and, as is often the case, they are but imperfectly covered or otherwise protected at the top to guard against persons falling therein.”

Fleck’s solution is basically a ladder set into the wall of the vault. Good for him, I guess. I hope he wasn’t inspired by some personal tragedy.

Likeness

At left is the official White House portrait of John Quincy Adams, painted by George Peter Alexander Healy. At right is a daguerreotype of Adams in 1843, when he became the first president to be photographed.

In a diary entry for Aug. 1, 1843, Adams noted that four daguerreotypes had been taken and pronounced them “all hideous.” Three more were taken the following day, but he found them “no better than those of yesterday. They are all too true to the original.”

That raises an interesting question: Which of these images is the more revealing record of the man? In Puzzles About Art, philosopher Matthew Lipman asks, “Which would we rather have, a portrait of Socrates by Rembrandt or a photograph of Socrates?”

Eternal Repose

https://www.google.com/patents/US964439

Angelo Lerro hated the thought of a body mouldering in a traditional casket, so in 1910 he offered this tidy alternative: The body is embalmed and arranged in a natural posture in a hermetically sealed glass bell filled with a preservative gas. This way the survivors can view the deceased without distress, and entire graveyards can be filled with sealed bells to keep soil and watercourses clean. (I suppose it will also keep down the vampire population.)

An even more permanent solution.

Box Scores

“It is probable that television drama of high caliber and produced by first-rate artists will materially raise the level of dramatic taste of the nation.” — RCA president David Sarnoff, 1939

“Television? The word is half Greek and half Latin. No good can come of it.” — Manchester Guardian editor C.P. Scott, 1928

“Television won’t matter in your lifetime or mine.” — Rex Lambert, The Listener, 1936

“Television won’t last because people will soon get tired of staring at a plywood box every night.” — movie producer Darryl Zanuck, 1946

“Television won’t last. It’s a flash in the pan.” — BBC school broadcasting director Mary Somerville, 1948

“How can you put out a meaningful drama or documentary that is adult, incisive, probing, when every fifteen minutes the proceedings are interrupted by twelve dancing rabbits with toilet paper?” — Rod Serling, 1974

“I hate television. I hate it as much as peanuts. But I can’t stop eating peanuts.” — Orson Welles, 1956

Rise or Fall

https://www.google.com/patents/US325437

Here’s an old-timey way to prevent oversleeping, patented by A.J. Nordmann in 1885. Set your alarm clock as normal but attach it to a lever on Nordmann’s “alarm and waking bed.” Now if you don’t turn off the alarm in time, the head of the bedframe will drop to the floor.

“Thus a person sleeping is awakened as the alarm sounds, and should he fail to rise he is immediately dropped down with the head portion of the mattress F, which then has its bearing upon the springs H.”

I suppose that really chronic oversleepers could remove the springs, to make the jolt even more jarring.

Inside Job

https://www.google.com/patents/US754217

Viennese inventor Adolf Herz patented this “portable bath or sack for washing or bathing purposes” in 1904. Fill it with “bathing agent or fluid,” step in, and close the upper end around your neck, and draw your soap, sponge, and towel from pockets in the interior.

Bathing or washing can be effected in the sack with every convenience. Splashing of water and wetting of the floor is thus entirely prevented. Also by means of the sack the evaporation of the water on the body otherwise taking place in bathing and washing is prevented, whereby the catching of colds is avoided. The bathing and washing can therefore be done in cool places. Also radiation of the heat of the body is considerably reduced, whereby a very agreeable sensation is produced when using the sack.

Afterward you can drain it through a runoff pipe. “After the sack has been emptied it can be folded together, so as to occupy a very small space, and then, if desired, tied or fastened together and kept in a bag, satchel, knapsack, or the like.”
