Abstract

A rotary terminal cleaner for cleaning terminals such as on automotive batteries and the like includes a cylindrical housing having an internal key running along the housing, an end cap having a cylindrical shape for mating with the hollow housing and forming a snug fit within an end of the hollow housing, the end cap having a longitudinal slot to mate with the key of the housing to prevent relative rotation of the end cap and the housing, the end cap also having a shaft integrally formed with the end cap for driving the cleaner by a rotary device such as a power drill. The cleaner also includes first and second brushes of abrasive material which fit within the hollow housing to abrade and clean the terminals. The first brush is a rectangular piece of abrasive material perhaps having bristles such as a section of a wire brush which fits in the end cap in such a manner as to permit the bristles to be facing the open end of the hollow housing. The second brush is a strip having a generally rectangular shape also having a plurality of bristles the second brush being formed in a circular manner within the hollow housing in such a manner as to be held in place by the key way on the inside of the housing and which in turn holds the first brush in fixed position.

Claims

1. Apparatus for cleaning cylindrical terminals, comprising:

a housing having first and second parts, said first part comprising a generally cylindrical member having an internal key, and said second part comprising an end cap having a slot therein for mating with said internal key in said first part to prevent relative rotation between said first part and said second part during operation; and

first and second abrading members located within said housing, said first abrading member being adapted to clean an exterior cylindrical surface of said terminal and said second abrading member being adapted to clean a flat end surface of said terminal.

2. Apparatus according to claim 1, wherein said first abrading member and said second abrading member further comprise a plurality of abrading elements, wherein a first group of abrading elements on said first abrading member interlock with a second group of abrading elements on said second abrading member for retaining said second abrading member in a fixed position relative to said first abrading member.

3. Apparatus according to claim 1 wherein said second part of said housing further includes a shaft integrally formed with said second part to adapt said apparatus for rotation by a power tool.
