SPECIFICATION forming partof Letters Patent No. 287,612, dated October 30, 1883;

Application filed June 21, 1883, (N model.) n

To all whom it may concern:

Be it known that I, HENRY B. BEACH, a citizen of the United States, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvementsin bench or block planes; and the object is to improve and simplify their construction, to dispense with the ordinary clamping iron, and form of the shaving-turningiron the clamping-plate, to be adjusted by a screw through the upper surface and bearing against the bit or cutting-iron, a fulcrum-point being also formed on said shaving-turning iron or clamping-plate, which. bears against the crossbar formed on the body or frame of the plane.

-The invention consists in the construction and arrangement of parts, as will be more fully described hereinafter, and more specifically pointed out in the claims, reference being had to the accompanying drawings and the letters of reference marked thereon.

V Like letters of reference indicate like parts in the different figures of the drawings, in

" Figure 1 represents a plan view of my plane.

Fig. 2 is alongitudinal section ofthe same on the line 00 m. Fig. 3 is a longitudinal section, showing the clamping-plate provided with the fulcrun1-point. Fig. 4 is a perspective view of the turning-iron.

In the accompanying drawings, A is the I body or frameof the plane,,cast with the ordinary opening, a, for the plane-iron 0r bit, and

. at the upper side with a cross-bar, b, as also withla lug, 0, having its upper surface-proor bit, and forms a fulcrum against it. By

screwing down the screw 6, the point of the shaving-turner is firmlyand evenly forced against the entire width of the bit, thus pre- Aeap, f, is cast 011 the turning-iron or clamping-plate, to prevent the hand coming in contact with the end of the bit or plane-iron.

Said cap is shown and claimed in another application filed April 4, 1883, I attached to a clamping-plate, and claimed therein.

The advantages of attaching the fulcrumpoint to the shaving-turning iron or clamping plate will be apparent to those skilled in the art, and amongthem are that a much longer fulcrum-point can be obtained. By adjusting the shaving-turning iron against the cross-bar onthe frame, the lower point can be clamped much tighter and closer against the plane-iron or bit, and the shavings are turned out of the way without clogging the plane, the necessity of a strong screw-driver for adjusting the shaving-turner against the bit is obviated, and the screw with a milled head is easier to. operate and to get at, and the cost of the plane is also greatly reduced. p

The old clamping-plate can be used by inserting a lug with point in the elongated slot, as now employed.

I am aware that a central bearing-point has been attached to the cross-bar on the frame, and a clamping-plate adjusted against it by a thumb screw; but said clamping-plate was plane, and could not form a shaving-turning iron, and I therefore disclaim such.

.I am aware of the Patent No. 144,823, granted to Baldwin, also Patent No. 7,565, granted to Traut and Richards, as well as N 0. 279,885, granted to Bust, and disclaim the con-' struetion therein shown; but

Having thus described my invention, what I claim, and desire to secure byLetters Patent, 1s
