Spring Loaded Brush

Abstract

A spring loaded brush is adapted for use in relatively inaccessible regions wherein access is obtained through an opening having a relatively small diameter. The brush employs an elongated handle base with a spring extension which is welded to the handle base. A wire harness secures a plurality of bristles and has a distal end with a protective chip. The harness is welded to the spring extension. In one embodiment, the brush tip has angled array of bristles in linear segments which have are oriented at an angle of 22.5°.

1 . A spring loaded brush comprising;
 an elongated handle base defining a longitudinal axis;   a spring extension having opposed ends, one end welded to said handle base and axially extending from said handle along the longitudinal axis; and   a brush tip having a plurality of bristles and secured by a wire harness and having a distal end with a protective tip and a proximal end which is welded to a second end of said spring extension.   
     
     
         2 . The spring loaded brush of  claim 1  wherein said brush tip has an angled array of bristles which radially extend from a pair of linear retaining segments oriented at an acute angle with respect to each other. 
     
     
         3 . The spring loaded brush of  claim 1  wherein the angle is approximately 22.5°. 
     
     
         4 . The spring loaded brush of  claim 1  wherein said protective tip has a rounded configuration. 
     
     
         5 . A spring loaded brush comprising;
 an elongated handle base defining a central axis;   an elongated spring extension having opposed first and second ends, said first end welded to said handle base and said extension axially extending from said handle base; and   a brush tip assembly comprising a harness having a first end with an integral protective tip and an opposed second end welded to said second end of said extension, said brush tip comprising a plurality of bristles generally radially extending from said harness.   
     
     
         6 . The spring loaded brush of  claim 5  wherein said handle base has a first substantially uniform diameter and said spring extension has a second substantially uniform diameter, said second diameter being less than said first diameter. 
     
     
         7 . The spring loaded brush of  claim 6  wherein said harness has a portion adjacent said second end having a third diameter, said third diameter being less than said second diameter. 
     
     
         8 . The spring loaded brush of  claim 6  wherein said plurality of bristles extend a radial distance which is approximately equal to said first diameter. 
     
     
         9 . The spring loaded brush of  claim 5  wherein said brush tip has an angled array of bristles which radially extend from a pair of retaining segments oriented at an acute angle with respect to each other. 
     
     
         10 . The spring loaded brush of  claim 5  wherein the angle is approximately 22.5°.
