The gas mask was invented in 1849 though and the traffic light? Hahaha

Perhaps the biggest misconception about his safety hood was that it was a gas maskā€”it was not and neither was it a forerunner for any type of gas mask. As a man of science, if Garrett Morgan were alive today he would be the first to point out how this would be impossible. The safety hood used a series of tubes to draw clean air off the lowest level the tubes could extend to. Smoke, being hotter than the air around it, rises, and by drawing air from the ground, the Safety Hood provided the user with a way to perform emergency respiration. If gas is not heated it is often denser than air around it and will sink to the lowest level it can.[20] Against gas, the smoke-hood would offer no protection and would actually facilitate the inhalation of gas rather than protect against it.

To deal with the growing problem of traffic accidents, a number of versions of traffic signaling devices began to be developed, starting around 1913.

In 1923, the U.S. Patent Office granted Patent No. 1,475,024 to Garrett Morgan for his three-position traffic signal. Though Morgan’s was not the first traffic signal (that one had been installed in London in 1868)

According to Popular Mechanics, “The common sponge was used in ancient Greece as a gas mask…”[4] An early type of rudimentary gas mask was invented in the 9th century by the Banu Musa brothers in Baghdad, Iraq. They described it in their Book of Ingenious Devices,[5][verification needed] mainly for protecting workers in polluted wells.[6]

Primitive respirator examples were used by miners and introduced by Alexander von Humboldt already in 1799, when he worked as a mining engineer in Prussia; long before that there was a Plague doctor’s bird beak shaped mask/face piece filled with herbs.

The forerunner to the modern gas mask was invented in 1847 by Lewis P. Haslett, a device that contained elements that allowed breathing through a nose and mouthpiece, inhalation of air through a bulb-shaped filter, and a vent to exhale air back into the atmosphere.[7] According to First Facts, it states that the “gas mask resembling the modern type was patented by Lewis Phectic Haslett of Louisville, Kentucky who received a patent on June 12, 1849.” [8] U.S. patent #6,529 issued to Haslett, described the first “Inhaler or Lung Protector” that filtered dust from the air.[9]

Early versions were constructed by the Scottish chemist John Stenhouse in 1854 and the physicist John Tyndall in the 1870s.

Another early design was the “Safety Hood and Smoke Protector” invented by Garrett Morgan in 1912, and patented in 1914. It was a simple device consisting of a cotton hood with two hoses which hung down to the floor, allowing the wearer to breathe the safer air found there.
