C. H. `WESION, OF NASHUA, NEW HAMPSHIRE.

SPOKESHAVE.

Specification of Letters Patent No. 20,459, dated June 1, 1858.

To all 'whom 'it may concern:

Be itknown that I, CHARLES H. lllrs'roN, of Nashua, in the count)7 of Hillsboro and State of New Hampshire, have invented a new and uselul Spokeshave; and I do hereby declare that the following is a full, clear, and eXact description ot the construction and operation of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l, is a perspective view ot the shave in readiness for operation; Fig. 2, is a view of the cap or holder; and Fig. 3, a section of the handle with the cap and cutter removed.

Similar parts are indicated by the same letters in all the iigures.

The nature of in v invention consists. first, in eonlining the cutter by means of a thumbscrew and a single metal plate so constructed as to operate both as a lever-cap and holder; second, in making said cap, or holder, acljustable so as to work in combination with the cutter, when desired, as the top-iron of a double-iron plane; and third, in providing the handle with concave projections on either side ot' the cutter, to serve as rests tor the fingers of the operator, when shoving the instrument from him.

To enable others, skilled in the art, to make and use my invention, I will now describe its construction and operation.

A A, Fig. l, is a metallic handle, cast in one piece, and ot any convenient size, like those in comuion use; l) (Fig. 3) being the opening for the reception of the cutter and delivery ot shavings.

B is a thin plate of metal, (a top view ot which is `given in Fig. 2) the underside being` a little concave, and the lower edge beveled like that of a plane iron.

Z) b are arms projecting each side of B, the top sides of which (see Fig. 2) are t'ure nished with little pins, or knobs, e, e.

a a are projecting arms, the under sides of which serve as fulcrums for the arms, b Z), of the plate B.

l, Q, and l, 2, are small holes (see Fig. 3) in the arms, o, a, into which the pins, or knobs, e, e, fit. Then e e are placed in holes, l, l, the lower edge of plate, B, is carried down so near to the cutter. C, as to answer for the upper iron of a` double-iron plane, or shave, and when in 2, 2, it operates as simply a cap and holder.

G is a thumb-screw passing through a female screw in the plate B, until its point bears on the cutter, which (as is evident from Fig'. l) will bring the arms, Z), Z). against the fulcruln arms, a ai, and the lower edge of B against the lower part of the out.- ter, C; by which means the cutter can be quickly and securely fastened.

(l Z are the concave projections in the trame, on both sides ot the cutter (as seen in Fig. l) to serve as rests t'or the fingers of the operator when shoving` the instrument from him.

B v loosening the tlnunb-screw, G, the cutter can readily be adjusted so to take anj7 thickness ot' shaving. or be removed in order to be sharpened.

The method in which the shave can be used either as a single, or double-iron shave, at pleasure. b v means ot' the adjustable cap, or holder. B. has been explained above.

1What I claim as my invention and desire to secure bv Letters Patent, is

1. The plate. B, provided with arms, Z), I), so as to operate, substantialljT as set forth, in combination with the tulcrum arms, a, a. and thumb-screw G and projections both as a cap and holder to the cutter, C.

2. lalaking,- the cap or holder, B, adjustable bv means of knobs, e e, and holes, l 9., or their equivalents, so that it majT operate either as a simple cap and holder to the cutter, C, or in combination with it, as the upper iron of a double-iron plane, substantiallj7 as described.
