The History Of Tattoo MachinesThe history of tattoo machines go a long way back.The predecessor to the tattoo machine was the electric pen invented by Thomas Alva Edison and patented under the title Stencil-Pens in Newark, New Jersey, United States in 1876. It was originally intended to be used as a duplicating device, but in 1891, Samuel O'Reilly discovered that Edison's machine could be modified and used to introduce ink into the skin, and later patented a tube and needle system to provide an ink reservoir.
While O'Reilly's machine was based on the tattoo rotary technology of Edison's device, modern tattoo machines use electromagnets. The first machine based on this technology was a single coil machine patented by Thomas Riley of London, just twenty days after O'Reilly filed the patent for his rotary machine. For his machine, Riley placed a modified doorbell assembly in a brass box. The modern two-coil configuration was patented by Alfred Charles South, also of London. Because it was so heavy, a spring was often attached to the top of the machine and the ceiling to take most of the weight off the operator's hand.
