Abstract

An electric reciprocating file or polishing member held in a housing. The housing supports a motor for reciprocating an enclosure held within the housing. A spring is held within the enclosure and the file is shaped to be snapped in or pulled out of the spring for use.

Claims

1. An electric abrasive file comprising:

a housing including a handle, said housing supporting an electric motor capable of driving a reciprocating member and said housing including an enclosure support cavity having an external opening at a file end of said housing;

a clip support enclosure having an open end, said enclosure being slidingly held in said enclosure support cavity, said clip support enclosure being controllably reciprocated by said reciprocating member;

a generally U-shaped spring clip held by said clip support enclosure having a pair of spring arms and a spring base, said spring arms surrounding an open spring end and said spring base being at a closed end respectively of said spring clip, said generally U-shaped spring clip having an inward bend and an outward bend at each end of said spring arms of said U-shaped spring clip said generally U-shaped spring clip being held in said enclosure so that its open spring end faces the open end of said clip support enclosure; and

a file having an inner end, an outer end, a top surface and a bottom surface, a first side and a second side, an indentation in said first and second sides near said inner end, said inner end and said first and second sides adjacent said inner end being shaped to snap into and out of said spring clip whereby the file may be inserted into and removed from said clip support enclosure and into holding contact with said spring clip and reciprocated by the movement of said reciprocating member to provide a smoothing function to a work piece in contact with one of said top and bottom surfaces.

2. The electric abrasive file of claim 1 wherein said clip support enclosure has a base and a cap and when said base and cap are assembled there is a bar which holds the base of said spring clip in said clip support enclosure.

3. The electric abrasive file of claim 2 wherein said base and said cap are assembled, said clip support enclosure has a smooth top and a smooth bottom and a pair of sides.

4. The electric abrasive file of claim 3 wherein said cap has a pair of openings adjacent the sides of said cap and the base has a pair of tabs which fit into said openings of said cap so that the cap and base are fixed together when said clip support enclosure is held in said support cavity.

5. The electric abrasive file of claim 4 wherein said clip support enclosure has a pair of openings in sides thereof to permit an outward flexure of said spring arms of said spring clip.

6. The electric abrasive file of claim 1 wherein an intersection of said inner end of said file and the sides thereof are rounded.

7. The electric abrasive file of claim 1 wherein said clip support enclosure supports a pin which holds an end of said reciprocating member.

8. An electric file which holds an abrasive stick and causes it to reciprocate in and out when activated, said electric file and abrasive stick comprising:

a housing enclosing means for reciprocating a driven member, said housing having a file end;

a cavity having an opening at the file end of said housing;

a clip support enclosure comprising said driven member held within said cavity, said clip support enclosure having an outer surface which is slidingly retained in said cavity, said clip support enclosure holding two biased open arms, said clip support member having an open end positioned in front of the two open arms, said two arms being flexible and each having an inwardly facing protrusion thereon; and

a file having an inner end, an outer end, a top surface, a bottom surface, a first side and a second side, said file having two outwardly facing indentations in each side thereof near the inner end, said file and said two outwardly facing indentations being shaped to mate with the inwardly facing protrusion of said biased open arm whereby said file may be pressed into the open end of said clip support member into the two biased open arms and held thereby while being reciprocated by said driven member and removed by pulling the file out of the biased open arms.

9. The electric file of claim 8 wherein said clip support member is fabricated from a polymer having a low coefficient of friction in said generally rectangular shaped cavity.
