Abstract

This invention is intended to improve the electromagnetic coil technology currently used in tattoo machines. Existing coil technology generates electromagnetism that causes a round steel post to alternately repel and attract an armature bar, moving a needle bar and attached needle groupings into and out of the skin in the act of tattooing. The Square Electromagnetic Coil Bobbin Assembly uses a square steel post instead of a round post, increasing the surface area where the post contacts the armature bar and improving the magnetism and general movement of the bar. Increasing the amount of metal-to-metal contact results in significant improvements in the overall functioning of the tattoo machine and the operator'"'"'s ability to achieve more solid color, smoother shading, and more consistent lines, all of which depend on the rate of movement of the armature bar. The Square Electromagnetic Coil Bobbin Assembly also uses removable instead of non-removable retaining washers and O-rings for the magnetic wire to allow the operator to customize and repair the magnetic wire.

Claims

1. What we claim as our invention is the square electromagnetic coil bobbin assembly as shown in FIG. 3, including the steel posts, retaining washers, o-rings, insulation tape, windings, and protective tape.
