Tattoo machine

time2010/08/20

A tattoo machine is a hand-held device generally used to create a tattoo, a permanent marking of the skin with indelible ink. Modern tattoo machines use alternating electromagnetic coils to move a needle bar up and down, driving pigment into the skin. Tattoo artists generally use the term "machine", or even "iron", to refer to their equipment.
History
The basic machine was invented by Thomas Alva Edison and patented as the 'Electric pen' or 'Stencil pen' in Newark, New Jersey, United States in 1876. It was originally intended to be used as an engraving 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.
The technology used to make modern tattoo machines has come a long way, however. While O'Reilly's machine was based on the rotary technology of Edison's engraving 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 door bell 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.
Most modern tattoo machines can control needle depth, speed, and force of application, which has allowed tattooing to become a very precise art form. Such advancements in precision have also produced a style of facial tattooing that has attained mainstream popularity in America called dermapigmentation, or "permanent cosmetics".
From "Basic Fundamentals of Modern Tattoo"
The basis of the modern tattoo machine is still relatively unchanged from the 1820 discovery by a Danish inventor Hans Christian Oersted called electromagnetism (Brian & Cohen 2007). Oersted’s invention is now known, in what is commonly implemented as a prime motor for the doorbell circuit, as the basis for all modern coil tattoo systems. Modern tattoo is symbolized by the advent of the mechanized version of the emplacement of some form of ink or dye under the skin. The basic usage was first transposed from an invention patented in 1876 by Thomas Edison (U.S. Patent 196,747). Edison’s machine was not intended for the skin, but for creating embroidery patterns by means of an electric punch. This concept was further elaborated on in 1891 by Samuel O’Reilly, who took a modified version of Edison’s now dual coiled mechanism and deemed it proper for skin tattooing (U.S. Patent 196,747). It is argued that O’Reilly was the inventor, even though it is actually Charlie Wagner who holds the 1904 patent for the “tattoo machine”.This patent demonstrates that the “tattoo device” has an ink chamber or “tube” and uses the single coil method for movement of the armature bar. In 1929 Percy Waters received his patent for the dual coil tattoo machine, which was set in a frame (U.S. Patent 1724812). Another patent was issued in 1979 to Carol Nightengale, who made some substantial modifications to the frame (U.S. Patent #4159659). Some of Nightengale’s modifications can be seen today in cutback machines, and fully adjustable frame styles. Nightengale’s version was also the first patented design that utilized front and rear spring apertures. While the history of the modern machine appears just as obscure as that of the history of the ancient process of tattoo, it is obvious that there were many individuals working toward the same concept. Even today there are many innovations such as the “swash drive” or bearing driven rotary machine, the “pneuma” which is run off air compression and cuts the coils and electromagnetism completely out of the machine, and the contactless machines which avoid the use of spark and utilize vibration to move the armature bars. Advances in coils from 6 to 16 wraps are also available.Tattoo machines have evolved in many ways, but the primary goal has remained the same over the ages; to put ink into the skin. The speed and accuracy that this is achieved has evolved over time, and the inks and pigments used have also changed. There are many exciting things being developed and with the information age of the Internet being upon us currently, the knowledge of machine builders and the number of tools available to tattoo artists around the world is expanding at an exponential speed. Even with all these advancements in the tattoo world, it is not uncommon to still see tattoo rituals performed in places like Japan and American Samoa the same way that they have been done for centuries.
