In 1881, Edison filed for a patent for a method to preserve fruits, vegetables and other organic substances in a glass vessel. The vessel was filled with the items to be preserved, and then all the air was sucked from it with an air pump. The vessel tube was sealed with another piece of glass. This invention came about from his work with vacuum pumps while developing long-life incandescent light bulbs.
Made with air-impregnated foam to keep the weight at only one-and-a-half times that of wooden furniture, Edison's line of concrete furnishings would be sanded and smoothed into a mirror-like finish or stained to look like wood grain. He claimed he could furnish an entire house for less than $200. In 1911, Edison's company molded a piano, bathtub and cabinets that could house Edison's phonographs.
Patented in 1890, Edison developed miniature phonographs and inserted them into dolls. The phonograph was enclosed in a tin casing that comprised the doll's chest, then pre-made arms and legs were attached, along with a bisque head made in Germany. The talking dollies sold for about $10.
In 1877, Thomas Edison first suggested using the word "hello." Before this, telephone users would often pick up the phone with phrases like, "Do I get you?" and, "Are you there?" But Edison found "hello" to be much more efficient, and the word caught on quickly - much to the dismay of Alexander Graham Bell. The inventor of the telephone preferred using the seafarer’s phrase "ahoy" to begin a conversation instead.
In the early 1880's, Edison discovered what is known today as thermionic emission, as a by-product of his work with improving early incandescent light bulbs. He patented the "Edison Effect" and actually used it as part of his first electric utility system in NYC. However, later this discovery became the basis for the diode and triode vacuum tubes that lead to modern technology we know today like radio, television and even phones!
In the 1920's, Edison's company released a line of luxury kitchen appliances, one of which was the automatic toaster. Many cheaper toasters were being invented and sold around this time, but what made these unique was that it used two compartments for the toast that opened automatically when it was done, instead of the springs popping the bread up. It was marketed for its speed - Toasting 2 slices of bread at once to the degree of toasted you set it at (and never burning)!
