Escape Suspenders

https://www.google.com/patents/US323416

In 1885 George C. Hale had the bright idea of weaving a zigzag cord into a pair of suspenders. Now if the wearer is trapped in a burning building, he can free the cord, lower it from a window to receive a rope, and escape to safety.

Hale’s patent application says, “I have found by experimenting that from fifty to one hundred feet, or even more, of the cord can be secured to the suspender in the manner heretofore described.”

The application was granted. I wonder if he ever went into business with this.

Bright Idea

Robert Heath thought we should all wear luminous hats. Confronted with the resounding question Why?, he offered this poetic paragraph:

Among the advantages of the invention are, the facility of seeing and finding the hat, &c., in closets and dark rooms and places, the presentation of a hat, &c., of different shades during day and night, the beautiful appearance of the article when worn at night, and the provision of distinguishing or indicating the localities of those who may wear the hats, &c., whose occupations are dangerous, such as miners, mariners, &c. For persons who are exposed to weather, sea, &c., the head-wear will be suitably waterproofed, so that the self-luminous nature thereof will not be injured by water.

Simple enough. His patent was granted on Feb. 27, 1883.

Green Activism

There must be a story behind this one: In 1900 Ludwig Ederer patented an “alarm bed” to wake an attendant when a greenhouse grows too cold.

If the steam pressure in the boiler drops, the bed suddenly tilts upright, “so that the sleeper will slide or roll off, thus reminding him that the steam within the pipe system is below a certain point, endangering the life of the plants within the greenhouse.”

After he’s stoked the fire the attendant can go back to bed and dream about getting a better job.

Tipu’s Tiger

When British forces plundered the palace of Indian prince Tipu Sultan in May 1799, they found an infuriating trophy:

In a room appropriated for musical instruments was found an article which merits particular notice, as another proof of the deep hate, and extreme loathing of Tippoo Saib towards the English. This piece of mechanism represents a royal Tyger in the act of devouring a prostrate European. There are some barrels in imitation of an Organ, within the body of the Tyger. The sounds produced by the Organ are intended to resemble the cries of a person in distress intermixed with the roar of a Tyger. The machinery is so contrived that while the Organ is playing, the hand of the European is often lifted up, to express his helpless and deplorable condition.

Tipu had allied himself with France against the encroaching East India Company, and the Fourth Mysore War brought his downfall. The tiger, it appears, had symbolized his defiance of British colonialism. The instrument was removed to London, where it became a centerpiece in the Company’s Leadenhall Street gallery; John Keats saw it there and immortalized it in The Cap and Bells, his satirical verse of 1819:

Replied the Page: “that little buzzing noise,
Whate’er your palmistry may make of it,
Comes from a play-thing of the Emperor’s choice,
From a Man-Tiger-Organ, prettiest of his toys.”

“Indeed, the horrific image of a wild beast attacking a helpless fellow Briton must have stirred strong reactions in the British audience so few years after the brutal Mysore campaigns,” write Jane Kromm and Susan Benforado Bakewell in A History of Visual Culture (2010). “Contained within one wondrous work of art was an illustration of the intensity of resentment toward European imperialism, the ferocious power of the enemy prince, and the moral justification for colonization.”

A Human Cantilever

To illustrate the design principle behind Scotland’s Forth Bridge, engineer Sir Benjamin Baker offered a personal demonstration. Sir John Fowler (left) and Baker (right) each hold two wooden poles with outstretched arms, forming two diamond shapes. When construction foreman Kaichi Watanabe sits in the center, the diamonds are prevented from tipping inward because their outer ends are anchored.

It worked. The bridge, opened in 1890, held the record as the world’s longest single cantilever bridge span for 17 years.

Chebyshev’s Paradoxical Mechanism

Russian mathematician Pafnuty Chebyshev devised this puzzling mechanisms in 1888. Turning the crank handle once will send the flywheel through two revolutions in the same direction, or four revolutions in the opposite direction. (A better video is here.)

“What is so unusual in this mechanism is the ability of the linkages to flip from one configuration to the other,” write John Bryant and Chris Sangwin in How Round Is Your Circle? (2011). “In most linkage mechanisms such ambiguity is implicitly, or explicitly, designed out so that only one choice for the mathematical solution can give a physical configuration. … This mechanism is really worth constructing, if only to confound your friends and colleagues.”

A Jump Ahead

http://commons.wikimedia.org/wiki/File:Marion_Tinsley.jpg

Mathematician Marion Tinsley lost only seven games of checkers in a career that spanned 45 years. Between 1950 and 1995, he took first place in every tournament in which he played. “Dr. Tinsley has taken the game beyond what anybody else ever conceived,” International Checkers Hall of Fame founder Charles Walker told Sports Illustrated in 1992. “No one presumed to think they could beat him.”

His last and best opponent was a machine, Chinook, designed by University of Alberta computer scientist Jonathan Schaeffer. When the American Checkers Federation refused to let a machine play for the championship in 1990, the sporting Tinsley resigned his crown and immediately accepted the match.

He won 4-2, with 33 draws. In one game, after the program had played its 10th move, Tinsley said, “You’re going to regret that.” Chinook resigned 26 moves later, and in the ensuing analysis Schaeffer found that Tinsley had looked 64 moves ahead to find the only winning strategy. (When asked for the source of his advantage, Tinsley, a lay preacher, said, “I’ve got a better programmer — God.”)

But the machine kept improving, and Tinsley’s health began to fail. He had to withdraw after six draws in their 1994 rematch, and he died of pancreatic cancer shortly afterward at age 68.

Chinook has since solved the game — after 18 years of thinking, it produced a map that would show it a non-losing move in any situation. In principle, at least, the computer is now invincible — the best a human can hope for is a draw.

This might have disappointed Tinsley, who played not for supremacy but for a love of the game. “Checkers can get quite a hold on you,” he said. “Its beauty is just overwhelming — the mathematics, the elegance, the precision. It’s capable of wrapping you all up.”
