Abstract
Abstract A tattooing device is provided which includes a motor housing and a needle housing secured thereto. A motor and an eccentric drive structure driven by the motor are mounted in the motor housing. In addition, a needle shaft and tattooing needle are mounted for reciprocation in the needle housing and are driven to reciprocate by the eccentric drive structure in the motor housing. The needle housing has an opening at the lower end thereof through which the tattooing needle reciprocates, and a silicone rubber bushing is mounted in the needle housing and is provided with an opening through which the needle extends. The diameter of the bushing opening is less than the diameter of the opening in the lower end of the needle housing so that the bushing operates to constrain transverse movement of the reciprocating needle and thereby reduces noise, ink splatter, the tearing of skin, and improves line clarity. In a preferred embodiment, the motor housing is provided with a mercury switch for energizing and de-energizing the motor so that the tattooing device can be operated with only one hand.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A tattooing device for performing a tattoo, comprising: a motor housing and a needle housing secured to said motor housing, said motor housing having mounted therein a motor and an eccentric drive structure driven by said motor, a needle shaft and tattooing needle mounted for reciprocation in said needle housing and driven to reciprocate by said eccentric drive structure, said needle housing having an opening at the lower end thereof through which said tattooing needle reciprocates, and a bushing formed of noise reducing material mounted in the bottom section of said needle housing and having an internal opening through which said tattooing needle extends, the internal diameter of said bushing opening being less than the internal diameter of said needle housing opening so that said bushing operates to constrain transverse movement of said reciprocating needle and thereby reduces noise, ink splatter, and the tearing of skin and improves the line clarity of the tattoo produced.
Claim 2
Dependent Claim
155 words
A tattooing device for performing a tattoo, comprising: a motor housing and a needle housing secured to said motor housing, said motor housing having mounted therein a motor and an eccentric drive structure driven by said motor, a needle shaft and tattooing needle mounted for reciprocation in said needle housing and driven to reciprocate by said eccentric drive structure, said needle housing having an opening at the lower end thereof through which said tattooing needle reciprocates, and a bushing formed of noise reducing material mounted in the bottom section of said needle housing and having an internal opening through which said tattooing needle extends, the internal diameter of said bushing opening being less than the internal diameter of said needle housing opening so that said bushing operates to constrain transverse movement of said reciprocating needle and thereby reduces noise, ink splatter, and the tearing of skin and improves the line clarity of the tattoo produced.
Claim 3
Dependent Claim
24 words
A tattooing device in accordance with claim 1, wherein said eccentric drive structure includes means for reducing transverse movement of said reciprocating tattoo needle.
Claim 4
Dependent Claim
70 words
A tattooing device in accordance with claim 2, wherein said reducing means includes a boss mounted on the output shaft of said motor, said boss including an integral cam extending therefrom, said cam being connected to the head of said needle shaft to drive said needle shaft to reciprocate in said needle housing, said boss and said head being securely fastened to reduce transverse movement of said reciprocating needle shaft.
Claim 5
Dependent Claim
27 words
A tattooing device in accordance with claims 1, 2, or 3, wherein said motor housing includes a mercury switch mounted therein for energizing and de-energizing said motor.
Claim 6
Dependent Claim
40 words
A tattooing device in accordance with claims 1, 2, or 3, wherein said motor housing includes a mounting member having a recess formed therein, in which said motor is securely mounted to reduce motor vibration and to enhance quiet operation.
Claim 7
Dependent Claim
37 words
A tattooing device in accordance with claims 1 or 2, further including means for preventing said needle shaft from engaging the interior walls of said needle housing by increasing the space therebetween in order to reduce noise.
Claim 8
Dependent Claim
57 words
A tattooing device in accordance with claim 6, wherein said means for preventing engagement includes a needle housing wall which is relatively thin and a needle shaft having a relatively small diameter so as to increase the space between said needle housing wall and the needle shaft to thereby prevent engagement between said elements to reduce noise.
Claim 9
Dependent Claim
18 words
A tattooing device in accordance with claims 1 or 2, wherein said bushing is formed of silicone rubber.
