To all whom it may concern:

Be it known that I, CHARLES G. MILLER, of New Britain, in the county of Hartford and State of Connecticut, have invented an Improvement in Tonguing and Grooving Planes, of which the following is a specfication:

In Letters Patent No. 165,355, granted July 6, 1875, a plane is shown with two cutters and an intermediate groove for the tongue that is left upon the edge of the piece of wood, and there is a guide that can be turned around or reversed when the plane is to be used for grooving. In this plane there is but one guide for the face of the board, the guide having two sides, one of which comes against the board in planing the tongue, and the other comes against the face of the board in planing the groove after the guide has been swung around for that purpose.

My present improvement consists in the combination, with a tonguing and grooving plane and stationary guide, of a second guide that is movable in a plane parallel to the face of the stationary guide, so that the plane can be used in the ordinary manner for tonguing the edge of the board, the movable guide remaining out of the way while so doing, and upon depressing the movable guide it changes the tool into a grooving-plane, so that only one cutter is used to form the groove.

In the drawing, Figure 1 is a side view of the plane. Fig. 2 is an inverted plan. Fig. 3 is a section at x x, with the movable guide or fence out of use; and Fig. 4 is a section at the line y y, representing the plane as in use for forming a groove.

The stock a, handle b, and knob c, are of any usual or desired size or character. The two cutters e and f are also constructed in the ordinary way and clamped, preferably by levers and thumb-screws. The stationary guide or fence It is upon the plane-stock, and I runs against the face of the board in the ordinary manner when the plane is being used to form a tongue. The cutter e is of the same width as the tongue ; hence to use said cutter in forming a groove it is only necessary to introduce a movable fence or guide at the proper distance from the cutter to enable the work-man to use the plane for grooving the wood for the reception of the tongue.

I accomplish this object by using the movable fence or guide i that moves in a plane parallel with the face of the stationary guide k.

I have shown this guide i as sliding vertically in a narrow channel made through the plane-stock, and the guide i is attached at one side of a headed stud, k’, that passes through the hollow stud l upon the plane-stock.

The portion of the stock that forms the bed for the cutters is slotted or channeled to allow of the movement of this guide ; so, also, is the stud upon which the knob e is placed. When the guide fi is pushed down into position shown in Fig. 4, the plane is adapted to grooving, and when said guide is not needed, it is moved in the plane parallel to the face of the board so as to be out of the way when using the plane for forming the tongue. This guide i might be pivoted at one end and swing in the same plane of motion as aforesaid, in a manner similar to a knife-blade.

I claim as my invention —

The combination, with a tonguing-plane, having stock a, cutters e and f, and guide k, of the second guide or fence i, moving in a plane parallel to the face of the stationary guide, substantially as set forth.

To all whom it may concern:

Be it known that I, CHARLES G. MILLER, of New Britain, in the county of Hartford and State of Connecticut, have invented an Improvement in Tonguing and Grooving Planes, of which the following is a description and specification, reference being had to the accompanying drawings, where —

Figure 1 is a side view of a plane embodying my invention, the view showing that side of the tool upon which the shifting guide, hereinafter described, is hung. The tool is adjusted as a tonguing-plane. The view from this side is, however, precisely the same when the tool is adjusted as a grooving-plane. Fig. 2 is a front-end view of the tool adjusted as a tonguing-plane, showing the pivot, on which the shifting guide is hung, in central vertical section. Fig. 3 is a front-end view of the tool adjusted as a grooving-plane.

This invention is a device which is, at pleasure, a plane for tonguing the edges of boards, or a plane for grooving the edges cf boards to receive such tongues. It is a tool for use in making what is known to carpenters as “matched stuff,” and combines in itself both a tonguing and a grooving tool.

The invention consists in a shifting guide, which can be adjusted so as to leave both the knives or chisels uncovered, making a tonguing-plane of the tool; or it can be adjusted to cover one of the chisels or knives, making a grooving-plane.

The letter a denotes the metallic stock or body of the tool; b, the handle, and c the throat, down which runs what carpenters call the “iron” d, forked at its lower end into the two chisels d1 d2, which do the cutting. e denotes the wedge which holds the iron in place. The letter f denotes the shifting guide, eccentrically attached to the shaft i, hung and rotating in the socket g, attached to the stock a. The pin i1 runs into the top of the shaft or trunnion i, and forms, practically, a part thereof. The spring m, bearing between the shoulders g1 i2, presses the guide f constantly upward. In either adjustment, for tonguing or for grooving, the guide f is held to position by the pins n, (shown in dotted lines,) which project downward from the fingers o, which project side-wise from the stock a, three teats entering corresponding holes in the top of the guide f.

When the operator desires to shift the adjustment of the guide f, he presses downward upon the top of the pin i1 till the guide clears the pins n, when it can be readily rotated upon its pivot in the socket g from one adjustment to the other.

In place of the vertical movement allowed, by this construction and arrangement, to the guide f, I contemplate depriving the guide of this vertical play, and in place thereof make one of the pins n, or both of them, a spring-catch.

When the guide f is adjusted as shown in Fig. 2, both the chisels d1 d2 are left uncovered for work, and the tool forms a tonguing-plane. When the guide f is adjusted as shown in Fig. 3, one of the chisels is covered, and the tool forms a grooving-plane; and these differences of adjustment are due to the fact that the guide f is hung eccentrically upon its pivot.

I claim as my invention —

ln combination with the body or stock a and the chisels d1 d2, the guide f, having adjustments to cover and uncover one of the chisels, substantially as shown and described.
