Thomas Edison Drawing: The Important ones
Phonograph: while Edison was working on the telegraph and its variants the idea of recording sound on tinfoil-coated cylinders came across his mind.
In the year 1877, he made a machine with 2 needles, one for recording and another one for playback. As he spoke through the mouthpiece the recording needle would create indentations on the tinfoil-cylinder. He got patent for this on February 19, 1878.
This detailed Thomas Edison drawing of a phonograph gives a frontal and side view of the phonography.
Light bulb: the year 1879 marks the anniversary of the incandescent bulb which majorly replaced the gas lights.
An incandescent light bulb comprises a thread-like object or filament which gives off light when heated by an electric current. In the beginning, they used a platinum filament; being expensive it was later replaced with carbon filament. Furthermore, this highly coiled carbon filament offers great resistance to the current producing radiation. He got patent for this on January 27, 1880.

In the year 1880, Edison came up with a device which automatically records the current used and gives instant result. He got patent for this on April 26, 1881.
