Abstract

Convenient anodizing is provided through a pen form factor anodizing tool having a reservoir for holding anodizing fluid and an electrical cable connection communicating electrical power to a tip dispensing anodizing fluid from the reservoir at a anodizing voltage from electrical power through the electrical cable connection.

First claim

What we claim is:

1 . An anodizing pen comprising:
a housing extending along a housing axis between a first and second end, the housing sized to be grasped like a pencil by a user with the first end extending distally from a user's hand; a reservoir adapted to hold an anodizing solution; a valve; a metering tip extending from the first end and communicating through the metering valve with the reservoir to receive and release anodizing solution from the metering tip; and an electrical cable received by the housing and providing a conductor in electrical communication with anodizing solution passing through the metering tip.

2 . The anodizing pen of claim 1 further including an electrical control exposed through a wall of the housing to provide control of electrical voltage received on the electrical cable and communicated to the anodizing solution.

3 . The anodizing pen of claim 2 wherein the electrical control provides signals through the electrical cable to a remote power supply to adjust the voltage of that power supply and wherein the electrical cable conducts voltage from the power supply to the anodizing pen.

4 . The anodizing pen of claim 2 wherein the electrical controls include a first and second button increasing or decreasing the electrical voltage, respectively, by a predetermined increment.

5 . The anodizing pen of claim 2 further including a normally open electrical switch having an operator exposed through a wall of the housing and positioned between the electrical cable and the anodizing solution to cease providing electrical power from the electrical cable to the anodizing solution when the operator is not activated by the user.

6 . The anodizing pen of claim 5 wherein the normally open electrical switch includes contacts within the housing for disconnecting the electrical cable from the anodizing solution.

7 . The anodizing pen of claim 1 further including a releasable tip connector at the first end adapted to releasably receive the metering tip and to communicate anodizing solution from the metering valve to the metering tip.

8 . The anodizing pen of claim 7 wherein the metering tip provides a porous brush having independent multiple filaments conducting anodizing fluid there between.

9 . The anodizing pen of claim 7 wherein the metering tip provides a porous stylus sharpened to a point and conducting anodizing fluid therethrough.

10 . The anodizing pen of claim 7 wherein the metering tip provides a spring-loaded ball that may be pressed into the metering tip to release anodizing fluid.

11 . The anodizing pen of claim 1 further including a set of different interchangeable metering tips including the metering tip and selected from the group consisting of a porous brush having independent multiple filaments conducting anodizing fluid therebetween, a porous stylus sharpened to a point and conducting anodizing fluid therethrough, and a spring-loaded ball that may be pressed into the metering tip to release anodizing fluid.

12 . The anodizing pen of claim 1 wherein the valve provides a valve operator extending from the housing to control an opening of the valve and a flow of anodizing fluid from the reservoir.

13 . The anodizing pen of claim 1 further including a power supply receiving the electrical cable to provide electrical voltage to the electrical cable and providing a grounding cable for independent connection to a workpiece.

14 . The anodizing pen of claim 13 wherein the power supply is adapted to receive signals from the electrical cable from the anodizing pen to control the voltage provided to the electrical cable.

15 . The anodizing pen of claim 1 wherein the reservoir extends from within the housing from the second end and provides a resealable opening through which the reservoir may be filled.

16 . The anodizing pen of claim 1 wherein housing is constructed of an electrically insulating material.

17 . The anodizing pen of claim 1 wherein the housing provides a radial projection at the second end receiving the electrical cable along an axis substantially parallel to an axis between the first and second end.
