UNITED STATES PATENT OFFICE.

WILLIAM STEERS, OF SHERBROOKE, QUEBEC, CANADA.

BENCH- PLANE.

- SPECIFICATION forming part of Letters Patent No. 284,919, dated September 11, 1883,

' Application filed January 25, 1883. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM SrEERs, a citizen of Canada, residing at Sherbrooke, in the county of Sherbrooke and Province of Quebec, Canada, have invented certainlnew and useful Improvements in Adjustable Composite Bench Planes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in bench-planes; and it consists in the devices for adjusting the cap upon the cutting-iron, the movements of the cutting-iron, and the closing of the throat of the plane to suit the different materials to be dressed, and also in the construction of the metallic body or frame of the stock, all of which will be hereinafter more fully described, and set forth in the claims.

In the drawings forming a part of this specification, Figure l is a longitudinal vertical section. Fig. 2 is an under side view of the face of the plane. Fig. 3 is a plan view of the plane-iron on top. Fig. 4 is a plan view of the cap. Fig. 5 is a transverse section on w x of Fig. 1.

A is a lever, pivoted at at, having at its lower end a segment-rack, a, which meshes with a worm-gear, B, that is supported upon a proper bearing or standard, B, within the stock of the plane A, which is in this case secured by a screw, a, through the bottom plate, A. This bearing or standard B also supports the lever A, and forms a bed at b for the plane-iron I, against which it is pressed by the screw J.

In the planeriron, on top, is a groove, H, for the foot of the screw J. In the plane-iron I there are holes 1' i i, into any one of which the small end a of the lever A can be inserted and below the lever A is one of the holes j, for the insertion of the end of a set-screw, D. Said screw works in a nut, C, below the cap K, and through the orifice d in the cap, for a purpose to be hereinafter explained.

J is a straining or clamp screw,which works in the nut is on the end of the cap-iron K.

G G are studs projecting on the inside of the stock-frame A, to lock the cap-iron K.

E is a strong spring attached at top to a standard, E, and its lower end, 6, made .as wide as the throat of the plane, and forming a casing for the front edge, e, of it.

e is an adjusting-screw by which the spring E is made to close the throat to such an adjustment as may be required to suit the character of the material to be dressed.

The adjusting worm-screw B is set in the standard B by means of a neck, a, and a retaining-pin, c, which will allow the screw to be rotated, but prevents its withdrawal.

The bottom plate, A, is formed with wide grooves F F, in which are inserted hard-wood strips F F, as seen in section, Fig. 5.

The set-screw D is inserted in the hole j, and when the cap K has been properly adjusted to the plane-iron I, the screw Dis then tightened, so that the nut C clamps the capiron K in its position; and by this device-the plane-iron, when removed from the plane to be sharpened, will come to the same position each time, after being sharpened, without any further adjustment, as screw D will be dropped into the same hole each time.

The series of holes t t, 860., in the plane-iron I is for the purpose of being used successively as the iron is ground away in sharpening, and they are at such a distance apart as to be accommodated to the other devices in connection therewith.

I claim 1. In planes, the cap-iron K, provided with a slot, a-set-screw having a free end passing through said slot, which enters the plane-iron, as shown, and a clamping-nut for fastening the screw at any point in the slot, substantially as and for the purpose described.

2. The cap-iron K, having a clamping-nut and screw, constructed as described, in combination with the plane-iron having a series of holes, andthe lever A, which enters one of said holes, substantially as described.

3. The combination of the spring-plate E, located in the throat of a plane, with the standard E and the adj usting-screw e, substantially as and for the purpose described.

4.. The metallic face-plate having longitudinal ribs and transverse ribs forming the throat of the plane, combined with wooden strips, as F, inserted between the ribs, as set forth. p In testimony whereof I affix my signature, in presence of two witnesses, this l8th'day of December, 1882. I

WILLIAM STEERS. Witnesses:

JOHN WInLIAMsoN STOOKDALE, J. D. J OHNSON.
