TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES P. CARTER, of the city of'Poughkeepsie, iu the county of Dutchess, and State of New York, have invented a new and improved Implement for Sharpening Watch-Wood, used by watchmakers;

'and I do hereby declare that the following is a full, clear, and exact description.

The nature of my invention consists in providing a block of suitable size and form to receive an angularshaped knife or cutter, said knife being secured and held firmly in'plaee by a screw, the whole being rmly and permanently attached to the work-bench, tho wood to be pointed or sharpened being drawn across the knife and block by the hand of the workman. I

The manner in which watchmakers have heretofore sharpened the wood used by them has been by using a common pocket-knife, holding the wood in one hand and the knife in the other.

My improvement requires the-use of one hand only to sharpen thewood, while the other bandeau be holding a watch, or part of' a watch, the workman not being obliged to lay'the Work'down, as in the old Way, and much ,time is saved.

In the accompanying plate of drawings, my improvement in sharpening the wood is illustrated- Figure 1 being a perspective view. p

I Figure 2 a transverse or longitudinally sectional view, showing how the knife is situated and held in place by the screw. v

Figure 3 shows the knife or-cutter.

Similar letters of reference indicate like parts.

a representsV the block or holder lfor the knife, which I make of brass, or composition, or any suitable material. Upon the upper side of the block, at E, I makelan angular or -shaped groove, extending part the length of the block. At b, figi'l, I show the, position'of the cutting-portion of the knife. vD D are holes for the screws to secure the block tothe bench.` i

The knife Zi, iig.' 3, is pla-eed in the block, as shown in iig. 2, and is adjustable. The knife is heidiu'place by the screw e, which is forced against it, as shown in fig. 2. The knife, as seen at tig. 3, is madeof thin steel, and ofthe shape shown. The cutting-portion seen at E, iig. 33, is ground on both sides alike, which prevents it from taking too rank hold of the wood, and also gives space for the chips or shaviugs to pass through.

In using my improvement, after the block is properly secured to the bench of the workman, the operator takes the piece of wood and places one'end in the groove E, iig. 1, and draws it back and forth across the edge of knife b, and at the same time turning it in his hand. In this manner a sharp, round point is obtained, which v is then ready for use in cleaningr out the pivot-holes of clocks und watches, and for other like uses.

What I claim as my invention, and desire to secure by Letters Patent,'is- The block a, knife 7J, and screw c, when arranged and combined to operate substantially the same asshown and described. i
