In 1858, Hyman Lipman of Philadelphia patented a pencil with a groove in the tip, into which an eraser was glued. By the early 1860s, the Faber company made pencils with attached erasers. In 1862, Joseph Rechendorfer of New York City patented an improvement of Lipman's design and sued Faber. The United States Supreme Court determined that the idea of combining a pencil with an eraser could not be patented. The reason for this decision was the fact that combining the pencil and the eraser did not change the function of either. This decision opened the way for numerous companies to make pencils with erasers.

Nicolas Conte developed and patented the process used to make pencils in 1795. He used a mixture of clay and graphite that was fired before it was put in a wooden case.

In 1839, Charles Goodyear discovered a way to cure rubber and make it a lasting and useable material. He called his process vulcanization, after Vulcan, the Roman god of fire.

The first patent for attaching an eraser to a pencil was issued in 1858 to a man from Philadelphia named Hyman Lipman. But this patent was later held to be invalid because it was merely the combination of two things, without a new use.

So although the idea of a pencil and eraser is brilliant, the man who decided to combine the two in which most pencils are made today, has been thrown under the bus. Is there no fairness in this world.

On March 30, 1858, Hymen Lipman of Philadelphia, Pennsylvania, USA, received the first patent for attaching an eraser to the end of a pencil. It was later invalidated because it was determined to be simply a composite of two devices rather than an entirely new product.

I cannot find it anywhere, but I do know that the name of the part that connects them is called a ferrule.
