Abstract: An improved electromagnetic coil tattoo machine offers the operator the opportunity to customize the machine's structural and operating properties. An embodiment of the invention provides a tattoo machine having at least one electromagnetic support coil which may include a coil core which has threaded holes which accommodate fasteners used to structurally secure and support 2 or 3 piece sub-frame members which house the secondary components that a conventional one-piece frame would house—such as the spring/armature bar, the binding posts and the preferred tube vice system. Accordingly in one embodiment, the support coil assemblies themselves act as a primary structural frame member. In a further embodiment, the electromagnetic support coil assembly may also use removable instead of non-removable retaining washers and O-rings to retain magnetic wire windings such as to allow the operator to customize and repair the magnetic wire.

Abstract: Prior art electromagnetic coil technology in tattoo machines employs a round steel post to alternately repel and attract an armature bar retained by a spring, reciprocally moving a needle bar and attached needle groupings into and out of the skin in the act of tattooing. The present invention uses a hexahedron shaped steel post to increase the surface area contacted on the armature bar, improving the magnetism and general movement of the bar. The improved rate of movement of the armature improves the overall functioning of the tattoo machine including the operator's ability to achieve more solid color, smoother shading, and more consistent lines. Removable retaining washers and o-rings are employed to allow the operator to customize and repair the magnetic wire.

Abstract: An apparatus is disclosed for attaching a needle housing or tube to the frame of a tattoo machine which facilitates cleaning and sterilization. The apparatus, or tube vice, comprises a tube which houses a needle which moves in and out of the subject's skin during tattooing, a hollow cylinder, a split ring ferrule and a compression nut. The tube is inserted into the hollow cylinder and the ferrule slides over the tube. The ferrule, nut and the hollow cylinder have beveled edges which mate. The nut slides over the tube to screw onto the hollow cylinder thereby compressing the ferrule against the tube without bending or crimping the tube. A tube grip may be attached to the tube. A method of manufacturing the tube vice is also disclosed. The tube vice can be provided in kit format.

Abstract: On all modern tattoo machines, the tube grip is a removable part that houses the needle bar, which holds the needle groupings that move into and out of the skin in the act of tattooing. The tube grip and needle groupings must be removable to allow for cleaning and sterilization.

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.
