Tattoo machine

1. A tattoo machine for oscillating a tattoo needle, comprising:

a main housing;

a motor secured to the main housing;

a needle bar member movably secured to the main housing for linear oscillation relative thereto;

a drive mechanism operatively connected to an output shaft of the motor and to the needle bar member for translating rotary movement of the output shaft into linear oscillation of the needle bar member, wherein the drive mechanism includes:

an eccentric member fixed to the output shaft of the motor for rotation therewith, and

a cartridge operatively connected to the needle bar member and having a slot defined therein for complementarily receiving the eccentric member such that rotary movement of the eccentric member linearly oscillates the cartridge and thereby the needle bar member; and

a pair of magnets disposed axially within the main housing at one end of the cartridge for dampening oscillating movement of the cartridge and thereby the needle bar member, the pair of magnets including a first magnet and a second magnet, the first magnet arranged for synchronous movement with the cartridge and the second magnet mounted to the main housing, wherein an axial distance is defined between the pair of magnets when the cartridge is at rest, said axial distance is adjustable while the cartridge is at rest, and wherein the second magnet is adjustably movable relative to the main housing for adjusting said axial distance between the pair of magnets.

2. The tattoo machine of claim 1 , wherein the cartridge includes:

a primary piston having the slot defined therein; and

a secondary piston slidably and nestably received within an axial recess defined within one end of the primary piston, the needle bar member fixed to the secondary piston for synchronized movement therewith.

3. The tattoo machine of claim 1 , wherein the second magnet is prevented from adjustment when a tattoo tube is installed and secured to the main housing.

4. The tattoo machine of claim 1 , wherein the pair of magnets are disposed at a lower end of the cartridge for dampening extended movement of the needle bar member.

5. The tattoo machine of claim 4 , wherein the pair of magnets is a first pair of magnets and the tattoo machine further includes:

a second pair of magnets disposed axially within the main housing at an upper end of the cartridge for dampening retracted movement of the needle bar member.

6. The tattoo machine of claim 5 , wherein another axial distance is defined between the second pair of magnets when the cartridge is at rest, and wherein said another axial distance is adjustable.

7. The tattoo machine of claim 1 , wherein the cartridge includes:

a primary piston to which the needle bar member is fixed for synchronized movement therewith.

8. The tattoo machine of claim 7 , wherein the cartridge further includes:

a sleeve member in which the primary piston is received, the sleeve member having an axially oriented sleeve slot through which the needle bar member extends and a cutout portion defined therein along which a cut-out portion of the primary piston slidably travels.

9. The tattoo machine of claim 1 , wherein the motor is fixedly secured within a motor housing that is removably secured to the main housing thereby allowing the motor housing and the motor to be selectively detached from the main housing.

10. The tattoo machine of claim 9 , wherein the motor housing is removably secured to the main housing by at least one magnetic connection.

11. A tattoo machine for oscillating a tattoo needle, comprising:

a main housing;

a motor secured to the main housing;

a needle bar member movably secured to the main housing for linear oscillation relative thereto; and

a drive mechanism operatively connected to an output shaft of the motor and to the needle bar member for translating rotary movement of the output shaft into linear oscillation of the needle bar member, wherein the drive mechanism includes an eccentric member fixed to the output shaft of the motor for rotation therewith and a cartridge operatively connected to the needle bar member and having a slot defined therein for complementarily receiving the eccentric member such that rotary movement of the eccentric member linearly oscillates the cartridge and thereby the needle bar member, wherein the cartridge includes a primary piston having the slot defined therein and a secondary piston slidably and nestably received within an axial recess defined within one end of the primary piston, the needle bar member fixed to the secondary piston for synchronized movement therewith,

and further wherein the primary piston includes a base wall defining a depth of the axial recess, the base wall configured to abut one end of the secondary piston when the eccentric member moves the primary piston in a first direction toward the secondary piston and is configured to move the secondary piston in said first direction with said primary piston.

12. The tattoo machine of claim 11 , wherein the primary piston includes a side wall defining a circumference of the axial recess, the side wall defining an axially oriented slot through which at least one of the secondary piston and the needle bar member is received, end portions of the side wall defining the axially oriented slot are configured to limit oscillating movement of the secondary piston and the needle bar member relative to the primary piston.

13. The tattoo machine of claim 12 , wherein the cartridge further includes a sleeve member in which the primary piston is received, the sleeve member having an axially oriented sleeve slot defined therein along which the axially oriented slot defined in the primary piston slidably travels, and the sleeve member having a cutout portion defined therein along which a cut-out portion of the primary piston slidably travels.
