Lette/rs Patent No. 86,295, dated .anfumfy 26, 1869.

IIMPROVEMENT IN BENCH-PLANES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it ma/y concern.-

Beit known that I, PHILANDER S. FOSTER, of Richmond, in the county of Sagadahoc, and State of Maine, have invented a new and valuable Improvement in Bench-Planes; and I do hereby declare that the following is a full, clear, and exact description of the con struction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, and to the letters and gures of reference- -c'ulty commonly called choking, by meansthat are more permanent and eicient than have heretofore been devised. l

By .my device, also, a wider bit may .be used, and consequently a wider shaving be cut, than by the ordinary bench-planes.

CVE-he letter A, of the drawings, represents the removable and adjustable Wooden front of the plane, and the letter B is the Wooden rear thereof.

The part A is constructed with a slot in its middle, running lengthwise, as shown on iig.2, adapted to hold and operate with the Athumb-screw C. This slot is marked H on the drawings.

The letters D are metallic plates, adjusted respectively on each side of the wooden parts of the plane, in the manner shown on gs. 1 and 3.

That portion of these metallic side plates respectively which is adjusted forward of the bit and throat, is constructed in' a bevelled form, as shown on iig. 3, and is adapted to corresponding grooves, cut in the sides of the part A, in which grooves it is held securely and rmly by the thumb-screw G,'in conjunction with its bevelled form so resting in its grooves.

The part A is cut oii square at its rear end, leaving a small bevel at the point c, upon which the hammer may be used.

I sometimes also arrange metallic boxings in the grooves of the part A, adjusted to the plates D. These boXings will save the Wear of the wood, and when properly oiled, will aid inthe adjustment of said part to the bit of the plane.

The thumb-screw C passes through both plates D and the slot H, and serves as a means of tightening, loosening, and fastening the part A, at the will of the operator.

The letter Eis the bit, and letter F is the Wedge of the plane. These are adj usted in diagonal slots, formed in the inner sides of the plates D respectively, in the manner shown on g. 2.

The fact that the bit and wedge are adjusted in plates of metal, instead of the Woodenthroat of the plane, as is usual, justifies the manufacturer in adapting a bit to the plane, that shall be wider, and consequently shall cut awider shaving than is prudent in planes wherein the bit is adjusted in wood only.

It will readily be perceived that by the upright formation of the rear end of part A, the 'plane is provided with a large open throat, which greatly lessens the dangerof choking, and that in case such Van event occurs, the chips in the throat may be easily loosened and removed, by moving the part A forward. This movementl is effected by unscrewing the thumb-screw C, and striking a gentle blow with a'hammer on the bevel c.

What I claim as my invention, and desire to secure nesses.
