Patent attributes
A tattoo machine apparatus is disclosed. The apparatus comprises a grip adjuster, a grip guide, and a ratchet disc. The components are arranged so that the grip adjuster houses a cartridge receiver and allows for needle depth adjustment while the grip guide ensures that the needle cartridge maintains its orientation and accepts the ratchet disc which provides positive stop adjustment and prevents unwanted rotation and thus accidental adjustment of the needle depth. In use, a backstem portion of a tattoo machine grip is inserted into the receiving portion of a tattoo machine. The tattoo machine is tightened down onto the backstem of the tattoo machine grip and holds it in place.
