To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full clear and exact description.

My invention relates to an improvement in planes, the object of the invention being to provide a simple and efficient plane construction which may be used for the purpose of accurately truing up or squaring up the edges of boards. Where heretofore various more or less complex constructions, including separate attachments, have been provided in conjunction with plane bodies for accomplishing this purpose, in the present invention the plane body itself is of unique construction, being integral throughout, the handle portion being so arranged that the pressure applied to the plane is in such a direction relatively to the work being done that said plane naturally seeks a true position upon the board being planed.

In the drawings Figure 1 is a plan view of the plane complete, ready for use and practically full size. Fig. 2 is a side elevation thereof. Fig. 3 is a front end elevation.

The frame is made of a single body casting and comprises two right-angle side fianges 1–2, which furnish the two right-angle bearing faces 1a–2a respectively. The flange 1 is continued upwardly at its front end to form an inclined and rearwardly facing thumb-rest 3. To the rear of the thumb-rest 3 and back of the middle line of the plane is a palm-rest 4 formed by a cross-web or flange set at an angle on the upper end of flange 1 and projecting above flange 2. This palm-rest is bulged to conform to the palm of the hand, so that the position of the hand upon the plane body will be such that pressure applied will cause both bearing surfaces 1a–2a to press uniformly upon the surface and edge of the board being planed. Upon the outer side of the plane is supported at a proper angle a cutter 5. The side flange 1 is provided with a throat, preferably oblique, in which throat the cutting edge of the plane iron or cutter 5 stands.

6 is a cap detachably held at the middle by the usual screw 7. 8 is a clamp screw at the rear of the cap, for causing said cap to properly engage the cutter to hold it tightly upon its support and in its properly adjusted position. The palm-rest 4 is preferably connected with the flange 2 by means of flanges or ribs 9–10, formed by widening the ends of the cross-web and which serve to rigidly hold the two flanges against distortion.

11 is a lug to support the cutter at its side edge to prevent it from turning during the progress of the work. The width of the cutter is such that it extends the full width of the bearing surface 1a.

12 is a reinforcing rib, which bridges the plane body at the end of the throat in which the cutter stands, so as to stiffen the same at this otherwise weakened point, due to forming the throat. The rib 12 is preferably extended around the forward end of the plane and also rearwardly back to the bulged palm support or bearing.

What I claim is :–

1. As an article of manufacture, a one-piece metal casting forming the body of a plane and comprising a work collocating tool guiding flange and a slotted tool carrying flange extending therefrom and forming a right angle, and an integral palm rest arranged at the rear end of said casting extending outwardly from and obliquely to the line of junction of said flanges and formed by a cross-web or fiange set at an angle on the upper edge of the tool carrying flange and which projects above the first mentioned flange.

2. As an article of manufacture, a one-piece metal casting forming the body of a plane and comprising a work collocating tool guiding flange and a slotted tool carrying flange extending therefrom and forming a right angle, and an integral palm rest arranged at the rear end of said casting extending outwardly from and obliquely to the line of junction of said flanges and formed by a cross-web or flange set at an angle on the upper edge of the tool carrying flange and which projects above the first mentioned flange, the ends of said web being widened to form flanges across the latter flange.

IMPROVED EDGE-PLANE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN E. PLUMMER, of Binghamton, in the county of Broome, and State of New York, have invented a new and useful improvement on Edge-Planes for trimming the edges of boots and shoes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which —

Figures 1 and 2 are perspective views, showing the concave and convex cutters.

Figure 3 represents the stock with the cutter-guard and throat detached.

Similar letters of reference indicate corresponding parts in each figure.

The object of my improvement is to construct a “reversible-edge plane” for trimming the soles of boots and shoes, which shall possess all the qualities requisite to accomplish the object with greater facility and ease, and at the same time to require less attention to keep it in order, than those in common use.

The nature of my invention consists in arranging a cutter on each side and in the centre of a stock, with a handle at each end. One of the cutters is designed for trimming the fore part of the sole, and the other for the “shank,” or that part under the instep, thereby combining in the same tool a cutter for the front or convex edges, and another for the “shank,” or concave edges of the sole.

It also consists in the simplicity of its construction and the adaptability of its form to accomplish the object designed.

I construct the stock A and the handles of cast brass, iron, or other suitable material. In the centre of the stock, I make projections B B on each side of the handles for the cutters C C, which are held in their places by the guard-plates D D, which are grooved to correspond with those in the stock, as represented in fig. 3, letters E E. The lower ends of said guard-plates are notched to fit into the shanks of the handles. The upper ends F F project above the face of the cutters, and are chamfered to work between the sole and the “uppers” of the boot or shoe, thereby protecting the work from injury. I then drill a hole, G, through the plate and into the stock, tap it, and enter the screw, but before turning it fully down, and while the guard-plate is still slightly loose, I enter the cutter into the grooves E E, and turn up the screw, which holds it securely in position. The throat H of the plane is made of steel, bent at right angles to the face, fitted between the guard and stock-back of the cutters, and the arm into a recess, I, held in place by a screw. The hole in the arm, through which said screw passes into the stock, is slightly elongated, for the purpose of graduating the shaving of the cutter. The stock A is chamfered down under the cutter and throat for the purpose of giving clearance to the shavings. The handles of the plane are slightly curved, and connect with the stock opposite, and their upper sides nearly flush with, the face of the plane or cutter on each side, so that when trimming the concave edges of the sole under the instep the opposite handle will not interfere with the work. One of the cutters is made straight for the purpose of trimming the convex edges of the sole. The other is curved to correspond to the concave edges under the instep.

The convex or fore part of the sole requires a “finer set” of the cutter than that of the shank or concave part, consequently manufacturers often use two instruments to accomplish the object rather than be constantly changing the “set” of the tool.

I am aware that there are many other arrangements for a similar purpose, but, so far as I know, there are none involving the combinations of my improvement. I therefore disclaim all interference with others, and confine myself to the novel features of my improvement.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is —

The construction and use of a “reversible-edge plane,” substantially as described and represented for the purpose set forth.
