Claim 17

The attachment of claim 1 wherein the deflector means is connected to the stop means.

Claim 18

The attachment of claim 16 wherein the deflector means and the stop means comprise a unitary body.

Claim 19

An attachment for removing material from a work surface, the attachment being for use with a hand-held vibrating-type power sander having a power driven platen having first and second opposite ends, first and second opposite sides, a bottom surface and a top surface, the attachment comprising: a metal plate means having top and bottom surfaces, a platen engaging portion, and a blade portion having a front edge; and connecting means for removably connecting the platen engaging portion of the metal plate to the platen with the top surface of the platen engaging portion of the metal plate means proximate the bottom surface of the platen, and the blade portion of the metal plate means projecting forward of the first end of the platen and being generally parallel to the platen, whereby the blade portion is power driven with the platen, said connecting means being positioned above a plane defined by the bottom surface of the blade portion thereby permitting the blade portion to be oriented essentially parallel to the work surface when power driven.

Claim 20

An attachment for removing material from a work surface, the attachment being for use with a hand-held vibrating-type power sander having a power driven platen having first and second opposite ends, first and second opposite sides, a bottom surface and a top surface, the attachment comprising: a metal plate means having top and bottom surfaces, a platen engaging portion, and a blade portion having a front edge; and connecting means for removably connecting the platen engaging portion of the metal plate to the platen with the top surface of the platen engaging portion of the metal plate means proximate the bottom surface of the platen, and the blade portion of the metal plate means projecting forward of the first end of the platen and being generally parallel to the platen, whereby the blade portion is power driven with the platen, said connecting means being positioned above a plane defined by the bottom surface of the blade portion thereby permitting the blade portion to be oriented essentially parallel to the work surface when power driven.
