UNITED STATES PATENT CFETCE.

GEORGE IQWEAVER, OF HARTFORD, CONNECTICUT.

IMPROVEMENT lN PLANES.

Specification forming part of Letters Patent No. 160,] 32, dated February 23, 1875; application filed May 23, 1874.

`part of this specification, and to the letters and iigures of reference marked thereon.

Figure l of the drawing is a representation of a sectional view of plane, and Fig. 2 is an end view of the same. Figs. 3 are detail views.

This invention has relation to hand-planes; and it consists in a novel construction of the stock-frame, having stationary inclined beds, and the adjustable wed ge having its upper beveled surface parallel with the cutting-iron, as hereinafter more fully described and claimed.

In the annexed drawings, A designates a metal plane-stock, which is constructed with two sides or cheeks, B B, the outer faces of which are perpendicular to the sole of the plane, as shown in Fig. 2. C designates the plane iron or bit, which is supported upon an adjustable bed, D, and a stationary bed, F, and which is rigidly secured thereupon by means of a clamp, G, which is pivoted to cheeks B, at g, and provided with a set-screw, g. The bed D is wedge-shaped, with an an- Y gle coincident to that of the stationary bed F,

and parallel with the plane or cutting iron, and is adjustable by means of a screw, E, which adjustment will allow the throat or month a to be enlarged or diminished as circumstances require. At the same time the wedge D affords a rigid support for the planeiron near its lower cutting-edge b. F represents a standard, extending upward from the stock, and having its upper end beveled at d, directly opposite the set-screw g of the clamp, to afford a bearing-surface for the upper portion of the cutting-iron C. By this construction the cutting-iron C is rmly secured at its lower and upper edges to the inclined beds F -clby means of the clamp G and set-screw gf, as shown in Fig. 1.

I am aware that a wedge arranged between the cutting-iron and the bed of the stock, operated by a screw to adjust the cutting-iron, is not new, and therefore I do not claim such invention, broadly but What I claim as new is- The hand-plane herein described, having the stationary inclined beds F d, the adjustable wedge-shaped bed D, having an angle coincident with that of the bed F, and a beveled surface parallel with the cuttingiron C, and affording, with the bed d, a rigid support for the same7 and the clamp G, with its setscrew g', all combined for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE L. WEAVER.
