History 5 Lesson 35

Combine Harvester

Hiram Moore was born in 1801 in New Hampshire. His neighbor, hascal, had  fled the Freemasonry affair. Hascall had a farm, but no workers to reap the harvest. Hascall told Moore about his wife’s dream. Moore developed the combine harvester in 1834, it was a miniature mobile grain factory. A fan and Archimedes screw sifted grain from chaff. Grains were bagged at the top. 30 acres harvested per baile, cost reduction of 80% (From $5 to $1) Moore’s harvester (all-in-one) was really too early, it also had several drawbacks. Received monetare support from Hascall and a US representative. They sent some to California to harvest over 600 acres of wheat (1854) 


Solar Compass

Willam Austin Burt was born in 1792,  he developed interest in nautical navigation. His life’s calling: was to help mankind, He was the inventor of several devices. Burt became a surveyor in the US government. Invented solar compass to solve compass to solve problems of magnetic interference in 1835. The solar compass didn’t rely on earth’s magnetic field. It was a complete instrument with movable parts to determine position. Burt won an award from the Franklin Institute. He made continual improvements,  he demonstrated at world’s fair in London. The US government made it a standard tool for it’s surveyors. 


Franacis Pettit Smith was born in England in 1808. He became a farming apprentice, he was fascinated by boats as a child. Smith grew interested in how boats were powered. He invented the screw propeller in 1835. The screw propeller had advantages over the  paddle wheel. It was lighter and more efficient. It helped ships rock less. Made boats are easier to navigate. Propeller converts rotational motion into “thrust” (linear motion) Another inventor patented a propeller 6 weeks after Smith did. He Began advertising to the Navy. His rival’s model didn’t impress the Navy. Smith convinced Brunell to use the propeller instead of the paddlewheel. 

       Mechanical Computer 

Charles Babbage was born in London in 1791. He became self-taught in math. Books of logarithms and data tables were vital in many fields. They contained errors, and Babbage wanted to fix that. He designed his “Analytical Engine” in 1835. Expanded capabilities beyond computing logarithms. He was programmable using punched cards. He did most actions of modern computers (loops, branches) It even had date memory. It would print tables automatically and accurately. Babbage never built the machine, Ada Lovelace was fascinated by the concept. She became the world’s first programmer. Babbage’s machine never received much publicity during his lifetime.
