This week in history I learned about the riveted blue jeans, fire sprinkler, the QWETY keyboard, and the dental drill.
The first thing I learned about this week was the riveted blue jeans. Expanding industry in the 1800s, demanded higher quality work clothes. Levee Strauss and Jacob Davis invented blue jeans in response to the demand for higher quality jeans in 1873. Featuring a unique riveted design to reinforce weak points in the jeans they are durable comfortable pants for some people. They spread among railroad workers and during the Dude Ranch craze They remain very popular today, and were a part of the historic but iconic ‘’uniforms’’ of the past.
The second ting I learned about was the fire sprinkler Fire extinguishers had been invented to handle smaller fires but the appearance of factories created need for better protection systems. Henry Parmalee invented the automatic fire sprinkler in 1874. It activates a water deluge when detecting heat from a fire. Parmalee educed insurance companies, and Grinnel improved his design. Grinnel’s legacy is the NFPA, which establishes and maintains fire protection requirements for buildings.
The third thing I learned about was the QWERTY keyboard. A series of fires broke out in the Midwest in 1871, even in the state of Wisconsin. Cristopher Latham Sholes. Working in Wisconsin invented the QWERTY keyboard layout in 187. It’s the world-standard layout that optimizes typing speed. Several typewriters tried competing, but they had different layouts and ultimately failed. The typewriter industry led to the computer industry, and the QWERTY keyboard helped ignite the smart phone industry.
The fourth and last thing I learned about was the dental drill. In the old days dentistry required slow-turning manual drills and painful procedures. George Green invented the dental drill by adapting the pneumatic drill with a electric motor. They turn at very high speeds to remove decay as painlessly as possible. Their low-pain benefits produced by their high speeds were advertised. Dental procedures today keep out teeth and gums healthy with relatively little pain involved when fixing dental problems.
I think the most interesting thing this week was the fire sprinkler, because when they tour on they look so cool and they help save people and buildings.
This week I learned about things that help with, fire, writing speed, and dental health.
