Air flow particle inhibiting cap for use with direct beam abrasion system

Abstract

A cap device for preventing an airflow streaming from an inlet bore of an abrasion contact tool to a plurality of outlet bores disposed thereabout. The cap device comprises a cap engageable to the abrasion contact tool having an inner surface. A bar formed or attached to the inner surface is provided that is positionable over the inlet bore to prevent the airflow streaming therefrom when the cap is engaged to the abrasion contact tool so as to allow the outlet bores to selectively exert a vacuum airflow exiting therethrough.

What is claimed is:  
     
         1 . A cap device for preventing an airflow streaming from an inlet bore of an abrasion contact tool, the cap device comprising: 
 a cap having an inner surface, the cap further being engageable to the abrasion contact tool; and    a bar attached to the inner surface, the bar being positionable over the inlet bore to prevent the airflow streaming therefrom when the cap is engaged to the abrasion contact tool.    
     
     
         2 . The cap device of  claim 1  wherein the cap is a plastic cap.  
     
     
         3 . The cap device of  claim 1  wherein the cap has a rear section and the abrasion contact tool defines a front end, the rear section of the cap being sized and configured to engage the front end of the abrasion contact tool.  
     
     
         4 . The cap device of  claim 1  wherein the cap has a front section with an opening, the opening of the front section being directable towards a target area.  
     
     
         5 . The cap device of  claim 1  wherein the bar is molded to the inner surface.  
     
     
         6 . The cap device of  claim 1  wherein the cap has a front and a rear section, the bar being diametrically extendable across the inner surface between the front and the rear section.  
     
     
         7 . The cap device of  claim 6  wherein the inlet bore defines a top end and the bar is strategically attachable between the front and the rear section so as to position the bar in abutting contact with the top end of the inlet bore.  
     
     
         8 . The cap device of  claim 6  wherein the bar is an elongate bar and the inlet bore is defined by a diameter, the elongated bar being sized to correspond to overlap the diameter of the inlet bore.  
     
     
         9 . The cap device of  claim 6  wherein the elongate bar has edges, none of the edges being extendable beyond the diameter of the inlet bore when the elongated bar is superimposed thereon.  
     
     
         10 . The cap device of  claim 1  wherein the elongate bar is defined by two ends having a width and an intermediate area therebetween further having a width, the width of the two ends being generally lesser than the width of the intermediate area.  
     
     
         11 . The cap device of  claim 1  wherein abrasive particles are disposed in the airflow streaming from the inlet bore.  
     
     
         12 . The cap device of  claim 1  wherein the materials are abraded particles to be extracted via the airflow exiting through the outlet bores.  
     
     
         13 . A method for utilizing a cap having an opening and a bar to prevent an airflow streaming from an inlet bore of an abrasion contact tool to a plurality of outlet bores disposed thereabout to create a vacuum force, the method comprising the steps of: 
 a) attaching the cap having the bar to the abrasion contact tool such that the bar superimposes upon the inlet bore in abutting contact thereto to prevent the airflow streaming therefrom; and    b) contacting said opening of said cap against a target area.    
     
     
         14 . The method of  claim 13  wherein the inlet bore has a periphery and the outlet bores are spaced uniformly around the periphery thereof.  
     
     
         15 . The method of  claim 14  wherein the cap has an inner surface and the bar is diametrically extendable thereacross.  
     
     
         16 . The method of  claim 13  wherein the bar is defined by two ends having a width and an intermediate area therebetween further having a width, the width of the two ends being generally lesser than the width of the intermediate area so as to provide greater access of the materials to the outlet bores when the intermediate area is superimposed upon the inlet bore.
