To all whom it may concern:

Be it known that I, EDWARD A. DUBEY, a

The invention mainly consists of a sheet of paper having Well defined and divided uncovered grooves or creases between sections that are covered with varying kinds of sand, emery, or like abrading substance.

In the accompanying drawings, Figure 1 represents a face view of a sheet of sand-paper constructed according to my invention. Fig. 2is an end or edge view of the same, and Fig. 3 a perspective View showing how the sheet can be folded.

A is a sheet of paper of suitable size. The same is provided with uncovered narrow portions to b c, which form creases or grooves, and with covered sections d e f, d e fiwhich are covered with sand, emery, or abrading substance.

the same time, he being able so to fold the sheet that the surfaces may either have the same kind of grain or difierent kinds of grain exposed for action at one time.

Instead of paper, cloth may be used as a foundation for this fabric.

What I claim is- 1. A sheet of sand-paper or the like having on its surface sections covered, respectively, with varying grades of abrading substance.
