DISHWASHER
The first dishwasher was patented in 1850 by Joel Houghton; his machine was a hand-turned wheel that splashed water on dishes - unfortunately, it wasn't very effective at washing dishes. The first working automatic dishwasher was invented by Mrs. Josephine Garis (W. A.) Cochran, of Shelbyville, Illinois, in 1889. Her dishwasher was a wooden tub with a wire basket in it - the dishes went in the basket, and rollers rotated the dishes. As a handle on the tub was turned, hot, soapy water was sprayed into the tub, cleaning the dishes. Cochran's machine was first shown at the 1893 World's Fair in Chicago, Illinois. At first, her machine was only bought by some restaurants and hotels. Cochran's small company was eventually associated with the KitchenAid company. The dishwasher didn't become widespread as a labor-saving machine until the 1960s.

SEWING MACHINE
Elias Howe (1819-1867) was American inventor who patented an improved sewing machine in 1846. His revolutionary machine used two separate threads, one threaded through the needle, and one in a shuttle; it was powered by a hand crank.

A sideways-moving needle with its eye at one end would pierce the fabric, creating a loop of thread on the other side; a shuttle would then push thread through the loop, creating a tight lock stitch. Earlier sewing machines used only one thread and a chain stitch that could unravel. Howe's business did not thrive. Others, like Isaac Singer made slight modifications in the machine and built successful businesses. Howe sued those who had infringed on his patent and won royalties on all machines sold (he was paid $5.00 for each sewing machine sold). Howe died the year his patent expired.

MECHANICAL REAPER
Cyrus Hall McCormick (February 15, 1809 - May 13, 1884) was an American inventor (of Irish descent) who developed the mechanical reaper. His new machine combined many of the steps involved in harvesting crops, greatly increased crop yields, decreased the number of field hands needed for the harvest, lowered costs, and revolutionized farming.

RUBBER BAND
The first rubber band was made in 1845 by Stephen Perry of the rubber manufacturing company Messers Perry and Co., in London, England. This rubber band was made of vulcanized rubber. Perry invented the rubber band to hold papers or envelopes together.

SAXOPHONE
Antoine-Joseph (Adolphe) Sax (1814 - Feb. 4, 1894) was Belgian musical instrument manufacturer and musician (he played the clarinet) who invented the saxophone. Sax first exhibited his newly-invented woodwind instrument at the 1841 Brussels Exhibition, and patented it in 1846. Sax also invented the saxhorn (a family of bugles with 3 or 4 valves), which he first exhibited in 1844.
