To all whom it may concern:

Be it known that I, CLIFFORD E. MARTIN, a citizen of the United States, residing at Greenfield, county of Franklin, State of Massachusetts, have invented certain new and useful Improvements in Core-Box Planes, of which the following is a full, clear, and exact description.

My invention relates to improvements in planes, and particularly to that type of plane termed a “core-box” plane.

The broad object of the invention is to provide a simple improvement in planes of the above type, by which improvement perfect segments of circles may be planed out with the greatest ease and accuracy. This feature of improvement and others will be more fully explained in the following description.

In the drawings, Figure 1 is a perspective view of the plane complete. Fig. 2 is a rear end elevation of the plane as it appears when actually in use. Fig. 3 is a front end elevation of the plane. Fig. 4 is a perspective view of certain details. Fig. 5 is a perspective view, partly broken away, of one of the details shown in Fig. 4.

The stock of the plane includes a suitable handle 1 connected to the main body, which latter includes the two side plates 2 and 3. The surfaces of these two plates are arranged in two planes intersecting each other at an angle of 90°.

4 is the plane iron. In this particular form the plane iron is arranged in a groove intersecting the surface of the plate 2, said groove being formed at a suitable rearwardly inclined angle relatively to the direction of movement of the plane iron during its cutting movement. The cutting edge of the plane iron is exposed at the meeting angle of the plates 2 and 3, and the groove in which the plane iron stands is preferably cut back at an oblique angle to the surface of plate 12 so that its cutting edge will be presented obliquely to the work, thus producing a draw-cut.

5 represents a clearance groove or recess formed in the side plate 3 and intersecting the meeting angle of plates 2 and 3, and of a width corresponding substantially to the width of the plane iron. This clearance groove 5 is of sufficient depth to provide for the proper thickness of shaving. The cutting edge of the plane iron, when properly adjusted, is coincident with the surface of plate 3 so that the extreme edge will be located accurately in one of the planes of the right angle.

A clamping device 6 is carried by the plane iron and passes longitudinally through the base of the handle 1 and wholly below the grip portion thereof. This clamping device has a hooked end 6a arranged to partially embrace the plane iron 4 as shown in Fig. 4.

6b is a suitable screw device arranged to engage the rear end of the body 6 of the clamping device, said screw device 6b being accessible at the rear end of the base of said handle. This clamping device 6 is arranged at an angle to the plane iron as shown in Fig. 4 so that when the adjusting screw 6b is set down the hooked end 6a of the clamping member will bind the plane iron firmly upon its seat.

As will new be seen, when the plane is used in the manner illustrated in Fig. 2, the cutting will be performed in such a way as to work out a groove of perfect semi-circular outline in cross-section. That part of the clearance groove 5 in front of the cutting edge of the plane iron permits the latter to encounter the material to be cut without projecting said cutting edge beyond or outside of the right angle. That part of the groove 5 to the rear of the plane iron operates to let the edge of the plane settle at each stroke whether or not said plane is drawn back sufficiently far to cause the plane iron to entirely clear the end of the groove. Thus short strokes may be employed to cut away tenacious portions of the wood. Were it not for this rearward extension of the clearance groove 5, the progress of the work would be very much impeded.

The usual throat to permit the escape of shavings is of course provided directly in front of the cutting edge of the plane iron through which chips and shavings will escape in the usual manner.

What I claim is:

1. In a plane of the character described, a stock having two diverging side plates the surfaces of which are arranged at an angle of 90 degrees relatively to each other, a plane iron having its cutting edge coincident with said angle and extending to one side thereof and in the plane of one of the side plates, and a clearance groove in said side plate extending forwardljv and rearwardly of the cutting edge of said plane iron.

2. In a core-box plane, a stock comprising two side plates the surfaces of which are arranged in planes intersecting one another at right angles, a clearance groove in one of said plates extending the full length thereof and coincident with the angle of intersection of said side plates, a plane iron carried by said stock, and means for detachably holding said plane iron in place, the cutting edge of said plane iron projecting into said clearance groove.

3. In a core-box plane, a stock including two side plates the surfaces of which are arranged in intersecting planes at right angles to each other, a groove in one of said sides intersecting the surface thereof for receiving a plane iron, a plane iron adapted to said groove, and rneans for detachably holding the same therein, a clearance groove in the surface of the other plate to the front and rear of the cutting edge of the plane iron and of a width corresponding substantially thereto.

4. In a core-box plane, two side plates the surfaces of which are arranged in planes intersecting each other at right angles, a clearance groove in one of said plates at and adjacent to the meeting angle of said planes and extending the full length of said side plate, a plane iron, and means for detachably holding the same, the cutting edge of said plane iron projecting into said clearance groove and being arranged to stand directly in one of said intersecting planes.

5. ln a plane of the character described, a stock having two diverging side plates the surfaces of which are arranged at an angle of 90° relatively to each other, a plane iron having its cutting edge coincident with said angle and extending to one side thereof and in the plane of one of said plates, and a clearance groove in said side piate extending forwardly and rearivardly of the cutting edge of the plane iron, a handle arranged in the angle between the two side plates, and a clamping device carried lay said handle and wholly below the grip portion thereof.

6. ln a plane of the character described, a stock having two diverging side plates, the surfaces of which are arranged at an angle of 90° relatively to each other, a plane iron having its cutting edge coincident with said angle and extending to one side thereof and in the plane of one of said side plates, and a clearance groove in said side plate forward of said cutting edge, a handle arranged in the angle between the diverging side plates, and a clamping mernber for the plane iron arranged in the base of said handle and accessible at the rear thereof for operation.

To all whom it may concern:

Be it known that I, EDWARD B, SHEPARDSON, a citizen of the United States, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Gages for Wood-Working Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in gages as attachments to woodworking planes; and it has for its object to provide an attachment to planes of hollow metal construction, one part of which is adjustable about an axis of motion to any required angle with reference to the bottom surface of the plane to which said gage is attached, so that a guide will be formed to fit against one surface of the material and slide against the same as the bottom of said plane rides over an edge of said material, cutting the same and forming an angle with reference to anotherside of said material greater or less than a right angle.

Mechanics who are in the habit of using wood-working tools are familiar with the difficulties encountered in beveling the edge of a board where the eye and feeling or judgment alone are depended upon in making the required angle. It is desirable, in view of such difficulties, that a good and simple device be provided, so that the operation of beveling may be only mechanical. Such devices have been invented, I am aware, as applicable to planes the stocks of which are of wood. My gage is intended to be applied to a plane the stock of which is of metal. My gage is formed, in the main, of two pieces of metal hinged together. One of said sections consists of a horizontal bar having at each of its two ends projections of T form, the bar, with its two ends, forming an H, as seen from the outside. Each of the T ends is bent inward nearly at right angles. The upper of these bent ends forms lugs for clamping-screws, and the lower of said bent portions is slotted and connected by a bracing-bar. The lower part of the gage is composed of a bar of U shape, the inner plane-surface of which is smooth, and the ends of said bar form tongues, which enter the slots in the upper portion of said gage where the two said parts are hinged together. Bifurcated pieces, forming clevises, project outward from the H -bar and the U -bar, and in these are pivoted or hinged screw-threaded nuts. A right-and-left screw provided with a thumb-piece on its center engages these nuts, and when operated increases or diminishes the angle between the two parts of the gage.

In my drawings, Figure 1 is an elevation of the gage as seen from the outside. Fig. 2 is a transverse vertical section of the same, showing the application of the gage to a plane and the relation of the latter to a piece of material being beveled.

Similar reference-letters indicate like parts in both of the figures.

Referring to the drawings, A is the horizontal bar of the upper portion of the gage, and B B’ are the T ends ofthe same, provided with bent portions a a’ b b’, the latter of which are connected by the strengthening-bar C.

d d’ are slots formed in the bent ends b b’, which receive the tongues e e’ of the lower portion of the gage.

D is the lower portion of the gage, formed as previously stated, the tongue ends of which are hinged in the slots of the T-pieces B B’. The long bar of the upper portion of the gage and the curved bar of the lower portion of the same have projecting from their centers outward bifurcated pieces or clevises E E’. In the outer ends of these clevises are pivoted swivel-nuts f f’, adapted to receive the right and left ends of the double screw F.

The bent T ends a a’ have screw-threaded openings to receive the screws G G’, the clamping ends of which latter may be threadless.

In applying this gage to a plane I place the bent portions a a’ on one of the side walls, with the long bar A resting against the outside of said wall and the clamping-screws — not yet driven down — against the inside of the same. The gage should be so placed upon the plane that one of the clamping-screws shall be in front of the handle and the other rearward of the same. When the screws are driven down to place, they impinge upon the bottom plate of the plane and draw the bent ends b b’ of the gage up against the bottom surface of said plane, and the gage is thus firmly held to place.

It may be observed that the interior angles between the T-pieces and portions a a’ are less than right angles, so that the screws when driven home find their places in the angle of the plane formed by the inner surface of the bottom and the inner surface of the said side wall. The gage being thus firmly secured to the plane, when the angle of the bevel to be made is determined the lower or U -shaped bar of the gage is moved about its axis by the right-and-left screw G G’ until the proper angle is formed. The gage is now applied with the plane to the piece of material to be planed in such a manner that the inner surface of the U-shaped bar rests against one side of said material and the bottom surface of the plane upon the edge of the same to be beveled.

The operator has only to keep the gage upon the guiding-surface of the material as he operates the plane to insure accurate work.

Having thus described my invention, whatl claim as new, and desire to secure by Letters Patent, is —

In a gage for use with wood-working planes, the combination, with the upper portion provided with clamping-screws, a swivel-nut, and jaws or bearings for the same, of the lower portion of said gage hinged to the said upper portion, provided with a swivel-nut and jaws or bearings for the same, and the right-and-left screw engaging said swivel-nuts to adjust the two portions, the one with reference to the other, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, DAVID C. ROGERS, a citizen of the United States, residing at Greenfield, in the county of Franklin and Commonwealth of Massachusetts, have invented a new and useful Improvement in Miter-Planers, of which the following is a true and full specification.

The accompanying drawings show the invention, and form part of this specification, in which —

Figure 1 is a plan showing the several features of my invention. Fig. 2 is a vertical central section of the same. Fig. 3 is a detail showing the rest G.

Similar reference-letters indicate like parts in all of the figures.

A represents the fixed bed-plate, semicircular in term, having at its rear the frame B, on which the plane runs, having a groove on its under side matching on a tongue to keep it true and steady. This bed-plate has on its outer upper edge notches placed at regular and fixed intervals, into which drops a catch from the upper bed-plate, to hold it securely at any angle desired.

C is the upper movable bed-plate, in quadrant form, having at right angles sides D D, which act as guides for the material to be planed, and revolving on a pivot at the rear end or apex touching the plane, passing through the lower bed-plate. These sides or guides are so accurately arranged with reference to the plane that when the movable bed-plate C is set with its center-line at a right angle to the plane a stick placed on either side will be planed to a perfect “miter.” The revolving movement of this bed-plate C is controlled by a screw and clamp, E, fixed in the upper bed-plate, and passing through a segmentally-shaped slot in the lower bed-plate, in which is a nut which clamps the upper bed-plate firmly in position when it is desired to fix it permanently at any given angle to the plane. This is commonly such as to finish the work at an angle of forty-five degrees, or a true miter. The movable bed-plate C is also provided at its outer edge with a small lever, F, controlled by a spring, and having on its under side a catch which is pressed down into the notches on the lower bed-plate, so arranged as to hold the stick to be planed at any given angle to the plane.

About midway in length of the sides D, and let in so as to be flush with the face of each side, is a rest, G, at the bottom of which is a segmental arm running back in ways on the movable bed-plate C, having through its length a slot through which into the said bed-plate passes a screw controlling its movement back and forth. The special purpose of this rest is to enable one to finish the ends of curved work with exactness.

In preparing pieces for circular or oval frames, for pulleys, emery-wheels, circular patterns, and all such work, it is necessary to plane the ends of the various segments composing the same at different angles, and when a curved stick is to be planed, the end must be closely pressed against the side or guide which supports it; but in doing this of course the other end of the curve is thrown out and away from the guide, as the stick can only touch the guide at the extreme end which is to be planed. Consequently, except at that point, the stick has no support but the unreliable action of the hand. To provide for this, the movable rest is run out till it touches the work on the outer curve, and then being secured by turning down the screw in the slotted segmentary arm forms a complete rest and support for the work to be planed.

This device supplies a want hitherto needed.

What I claim in a miter-plane is —

1. In a machine for planing miters, the quadrantal pivoted bed-plate, provided with segmental guardways fixed thereon, in combination with rests G, provided with segmental clamping-arms adapted to hold the material to be mitered in position for the planer, as and for the purpose set forth.

2. The combination, with the tired bed-plate A and frame B, of the pivoted bed-plate C, provided with adjustable rests G, substantially as and for the purpose set forth.
