UNITED STATES PATENT. OFFICE.

PHILIP B. STANLEY, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE STANLEY WORKS, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

, CARPENTERS PLANE.

To all whom it may concern:

Be it known that I, PHILIP B. STANLEY, a citizen of the United States of America, residing at New Britain, Hartford County, State of Connecticut, have invented new and useful Improvements in Carpenters Planes, of which the following is a specification.

My invention relates particularly to the cutter construction, and the main object is to provide a construction in which the cutting element is small and inexpensive and adapted to standard planes. course, becomes dull with use, and ordinarily it is necessary to re-sharpen it from time to time. This re -sharpening takes time and skill, as well as facilities which are not always handy. It has been proposed to turnish small, thin blades, to be used in conjunction with specially formed portions, and one of the objects of my invention is to furnish a blade which can be used with standard planes.

Another object is to provide a construction of this character in which the cutter is more securely fastened in place.

In carrying out my invention, I provide a comparatively thin detachable cutter, having what are sometimes called key-hole shaped openings, and which is adapted to be secured to the upper surface of the plane iron by means of correspondingly located screws.

Figure 1 is a side view and partial section showing a construction embodying the improvements of my invention.

Figure 2 is an edge view of the cutter and its carrier, shown substantially full size.

Figure 3 is a plan view of a fragment of the plane iron with the cutter attached.

Figure 4 is a plan view of the detached cutter.

Figure 5 is a transverse sectional view of the cutter and the supporting iron.

The plane may be of any suitable design or construction having a body 6 provided with such handle or handles as may be desired. 7 indicates the usual type of plane iron or blade adapted to be adjusted in and out by usual yoke 8 and thumbscrew 9, and adapted to be tilted from side to side by usual lever or arm 10.

The cutter 11 is made very thin, say approximately of an inch thick, I and it may have either pne or two edges This A cutter, of

cutter is secured to the iron 7 by means of a plurality of screws 12 which have threaded engagement in the iron. These screws also preferably have upset shoulders or flanges 13 to prevent the screws from being withdrawn from the iron. The'iron is preferably recessed at 14 to receive the shoulders 13.

The cutter is provided with slots each of which has a large portion 15 adapted to receive the head of the screw, and a smaller portion 16 adapted to accommodate the shank of a screw. lVhen the screws 12 are tightened, the cutter 11, in effect, becomes a rigid part of the iron 7. When the screws are loosened, the blade may be slipped sideways 'and then removed,

On account of the very thin and exceptionally flexible character of the cutter, I find it desirable to hold it adjacent its cutting edge by means of a cap plate 17 which is secured to the iron 7oby a screw 18. By tightening this screw, the tip of the cap 17 may be pressed tightly against the cutter adjacent the tip of the iron 7 so as to clamp the parts securely together. By having the cap 17 arched at 19, I provide sufficient room heneath it to allow for the heads of the screws 12. The two parts 7 and 17 constitute a support or carrier for the detachable cutter and this support is secured to the body of the plane by means of detachable lever 20,

adjusting screw 21, and campiece 22. The pressure of the cam is transmitted through the lever 20 to the arched portion 19 of the cap 17 and thence to the cutter adjacent'its operating edge and thence through the iron 7 to the body of the plane at the edge of the throat in the sole of the plane. The pressure of the lever 20 may be adjusted by the screw 21'.

The pressureof the cam piece 22 may be released and the lever 20 may be removed in the usual way. The adjustment of the cutter is efiected by adjusting the carrier parts I 7, 17 by means of the thumb screw 9 or the overstand the edges of the narrow ends of said slots to elamp said cutter to said iron.
