Abstract
Abstract A reciprocating tool in the nature of a dental handpiece is modified to carry a needle/cone assembly for use as a tattooing device. The needle/cone assembly includes a needle assembly trapped in a cone structure. The needle assembly includes a cap portion which is held by fingers in the handpiece to prevent rotation of the needle assembly, and a frangible neck which is broken on removal of the needle/cone assembly from the handpiece to prevent reuse of the needle assembly. A removable protective tube around the needles acts also as an insertion tool for the needle assembly.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
93 words
In a tattooing device including a housing, a needle retainer in the housing, and a drive means in the housing for reciprocating the needle retainer with respect to the housing, the improvement comprising a needle/cone assembly removably attached to the housing, the needle/cone assembly comprising a cone structure, means for removably attaching the cone structure to the housing, a needle structure, the needle structure being reciprocatably mounted in the cone structure, means for trapping the needle structure in the cone structure, and connecting means for connecting the needle structure to the needle retainer.
Claim 2
Dependent Claim
93 words
In a tattooing device including a housing, a needle retainer in the housing, and a drive means in the housing for reciprocating the needle retainer with respect to the housing, the improvement comprising a needle/cone assembly removably attached to the housing, the needle/cone assembly comprising a cone structure, means for removably attaching the cone structure to the housing, a needle structure, the needle structure being reciprocatably mounted in the cone structure, means for trapping the needle structure in the cone structure, and connecting means for connecting the needle structure to the needle retainer.
Claim 3
Dependent Claim
23 words
The improvement of claim 1 wherein the needle structure is snap-fitted to the needle retainer for reciprocation with respect to the cone structure.
Claim 4
Dependent Claim
59 words
The improvement of claim 1 wherein the needle retainer is tubular and wherein the connecting means comprise an enlarged cap part on the needle structure and finger means at an upper end of the needle retainer for engaging the cap part, the needle structure further including at least one needle extending below the lower end of the needle retainer.
Claim 5
Dependent Claim
49 words
The improvement of claim 3 wherein the needle structure includes a frangible part between the cap part and the at least one needle, the finger means on the needle retainer engaging the cap part sufficiently tightly that removal of the needle/cone assembly from the housing breaks the frangible part.
Claim 6
Dependent Claim
72 words
The improvement of claim 1 wherein the cone structure includes a frustoconical portion at its lower end and a cylinder part, the means for trapping the needle structure in the cone structure comprising an enlarged part on the needle structure in the cylinder part of the cone structure, and means at the upper end of the cylinder part cooperative with the enlarged part to trap the needle structure in the cone structure.
Claim 7
Dependent Claim
28 words
The improvement of claim 1 wherein the means for removably attaching the cone structure to the housing comprise cooperating threads on the housing and on the cone structure.
Claim 8
Dependent Claim
35 words
The improvement of claim 1 wherein the needle structure includes a frangible part, the connecting means engaging the needle structure sufficiently tightly that removal of the needle/cone assembly from the housing breaks the frangible part.
Claim 9
Dependent Claim
94 words
In combination, a device comprising a housing, a tool retainer in the housing, and a drive means in the housing for reciprocating the tool retainer with respect to the housing; a tool comprising a tool structure and a tool carrier in which the tool structure is reciprocable; one-way attachment means for attaching the tool structure to the tool retainer by a one-way fitting, means for removably attaching the tool carrier to the housing, and means in the tool structure for rendering the tool structure unusable upon removal of the tool carrier from the housing.
Claim 10
Dependent Claim
94 words
In combination, a device comprising a housing, a tool retainer in the housing, and a drive means in the housing for reciprocating the tool retainer with respect to the housing; a tool comprising a tool structure and a tool carrier in which the tool structure is reciprocable; one-way attachment means for attaching the tool structure to the tool retainer by a one-way fitting, means for removably attaching the tool carrier to the housing, and means in the tool structure for rendering the tool structure unusable upon removal of the tool carrier from the housing.
Claim 11
Dependent Claim
43 words
The combination of claim 8 wherein the means in the tool structure for rendering the tool structure unusable upon removal of the tool carrier from the housing is a part which is broken upon removal of the tool structure from the tool retainer.
Claim 12
Dependent Claim
49 words
The combination of claim 9 wherein the carrier is threaded to the device housing, the tool is snap-connected to the tool retainer as the carrier is threaded onto the device housing, and a frangible portion of the tool is broken as the carrier is threaded off the device housing.
Claim 13
Dependent Claim
62 words
A needle/cone assembly for use in a tattooing device having a housing and a needle retainer in the housing, the needle/cone assembly comprising a cone structure, quick-connect means on the cone structure for removably attaching the cone structure to the device housing, a needle structure reciprocatable in the cone structure, and means for permanently trapping the needle structure in the cone structure.
Claim 14
Dependent Claim
62 words
A needle/cone assembly for use in a tattooing device having a housing and a needle retainer in the housing, the needle/cone assembly comprising a cone structure, quick-connect means on the cone structure for removably attaching the cone structure to the device housing, a needle structure reciprocatable in the cone structure, and means for permanently trapping the needle structure in the cone structure.
Claim 15
Dependent Claim
27 words
The needle/cone assembly of claim 11 wherein the needle structure includes means rendering the needle structure unusable as the needle/cone assembly is removed from the device housing.
Claim 16
Dependent Claim
37 words
The needle/cone assembly of claim 12 wherein the needle structure is a needle assembly including a plurality of needles carried by a needle carrier, the means rendering the needle structure unusable being provided in the needle carrier.
Claim 17
Dependent Claim
46 words
The needle/cone assembly of claim 13 wherein the needle carrier includes an upper cap part, the upper cap part including means interengageable with the needle retainer in the device for snap-fitting the needle assembly to the needle retainer for reciprocation with respect to the cone structure.
Claim 18
Dependent Claim
