lNlPROVENl ENT IN PLANlNG-TOOLS.

Specification forming part of Letters Patent No. 113,800, dated April 18, 1871.

To all whom 'it may concern:

Be it known that I, NATHANIEL RUSSELL, of Plymouth, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Planing-Tool; and Iv do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art. to make and use the saine, reference being had to the accompanying ndrawing, 'forming part of this sp'eeiiication. l l

This invention relates to a new and useful improvement in tools for planing Wood and meta-ls; and consists in confining a series of steel plates in a hollow bloeit or case by means of a screw or keys or wedges, or in any substantial manner, sov that the plates may be conlined at any angle for use or for grinding, the cutting-.edges of the said plates being eitherI beveled or square, the construction and arrangement heilig as hereinafter more fully described.

In the accompanying drawing, Figure l represents a vertical longitudinal section of Fin'. 2, taken on the line a' af. Fig. 2 is a top or plan view.

Similar letters of reference indicate corresponding parts.

A is a hollow block or` 4case et' suitable size and strength, made of metal, with a fasteningscrew, B, passing throughiene end. C represents a series of thin steel plates, which correspond in width with the cavity in the block or case A, and which proie-et up above the block or ease, as seen in Fig. l, more or less, as may be desired. The plates lare of' uniform size, and all rest upon the bottom of the cavity in the block. The outer edges of these tion, as represented, so that sharp projecting cutting-angles will come in contact with the surface of the wood or metal, or other material to be plaued or smoothed, giving the face a fine saw-tooth appearance. i

The plates may be made with square edges and placed in an inclined position, and will operate in that manner; but the cutting-angles will, in that case, be simply right angles, and consequently not so sharp and well adapted to the purpose as -when the edges are heveled.

The plates may be fastened by one or more screws, or by keys or wedges arranged and operating on the plates-in any manner suit-a ble for the purpose et' holding them in any required position. l

When the cutting-edges become dull from use, they are fastened in the block at any angle which will give their edges the required bevel or shape, and then they are all ground together and of uniformi shape.

The planer may be applied to either wood,

metal, or other material, and he operated by
