To all whom it may concern:

Be it known that I, SIDNEY C. CARPENTER, a citizen of the United States, residing at West Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Convertible Planes; and I do 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.

My invention relates to convertible planes of that character designed to be used for planing curved or flat surfaces; and the objects of same are to provide a plane with a spring bearing-surface which may be readily and quickly adjusted to the required degree to bear upon surfaces of more or less curvature and which may be readily converted into a plane of the ordinary or usual construction provided with a flat bearing-surface.

Another object is to provide a plane of this character which may be quickly and accurately adjusted for use under varying conditions and which will be provided with means for adjusting cutting-blades or bits relatively, accurately, and quickly.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which —

Figure 1 is a side view of a plane constructed in accordance with my present invention and having the curved spring bearing-plate secured thereto. Fig. 2 is a perspective view of the spring bearing-plate detached from the plane. Fig. 3 is a perspective view of the fiat plane-surface which may be substituted for the spring when it is desired to convert the device into an ordinary plane. Fig. 4 is a vertical section on the line 1 1, Fig. 1. Fig. 5 is a longitudinal section on the line 2 2, Fig. 1.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the body portion of the plane, said body portion being oppositely inclined in front and rear, as shown at 2 3, and provided with suitable handles 4 5 and a cutter or bit 5a. A transverse slightly-curved surface 6 is provided at the central lower portion of the stock or body, and a lug 8, extending upward from the curved steel plate 9, is secured to the stock by a bolt 21, said plate forming the bottom or bearing surface of the plane. Near opposite ends of the plate 9 are lugs 10, projecting upward, said lugs being connected to links 11, pivoted at 12 and connected at their upper ends at 13 to longitudinal levers 14 and 15. Said levers 15 extend toward the middle of the frame upon opposite sides thereof and are connected by a pin 16, extending through the body or stock of the plane and through the front levers 14, a link 17 connecting said levers with a pivoted bolt 18, having fitted thereon a nut 19 for adjusting the levers 14 15 upon their pivots 20 to raise or lower the links 11, and thus adjust the spring-plate 9 to the required curvature for the work to be operated upon.

If it is desired to convert the plane into one of ordinary construction, the bolt 21 may be removed and the plate 22 substituted for the spring-plate in an obvious manner.

From the foregoing it will be obvious that my plane is of comparatively simple construction and may be readily converted from a circular to a flat-bottom plane. The curved steel plate may be readily adjusted to the required degree, depending upon the degree of curvature of the work to be performed.

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

A plane comprising a stock having oppositely-inclined bottom faces, a spring face-plate secured to said stock between said inclined surfaces, said face-plate having upwardly-extending end lugs, links pivoted to said lugs, levers pivoted to said links and extending longitudinally to the center of the stock, a pin connecting the meeting ends of said levers, a link connected to said pin, a bolt connected to said link, and a nut for adjusting the bolt, the levers and the spring, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SIDNEY C. CARPENTER.

Application filed June 26, 1902. Serial No. 113,228. (No model.)

To all whom it may concern:

Be it known that I, ALBERT E. CHURCH, of West Hartford, Hartford county, Connecticut, have invented certain new and useful Improvements in Carpenters’ Planes, which improvements are described in the following specification and are illustrated by the accompanying drawings.

My invention relates in general to wood-working-planes made of metal, and in particular to the stock or body of such planes.

It is the object of the invention to facilitate the construction of such stock or body by the manufacturer, and incidentally to render the action of the plane lively and elastic in the hand of the user. To accomplish these results, I form not only the sole of the stock, but also two side walls or flanges rising from the edges of the sole and two intermediate bridges extending across from one of said flanges to the other, all from a single sheet of metal, and upon such transverse bridges I seat the knob and the handle of the plane.

The best manner in which I have contemplated applying the principles of my invention is shown in said drawings, in which —

Figure 1 is a central longitudinal section of a plane which is constructed in accordance with those principles. Fig. 2 is a plan view of a stock-blank, being a flat sheet of metal, preferably cold-rolled steel, stamped out in suitable shape to be formed into the stock of said plane by bending. Fig. 3 is a perspective view of the plane-stock, including the frog-seat, in position.

In the views the sole of the stock and the side walls or flanges of the same are indicated, respectively, by the numerals 1 and 2. The wings 3 and 3 of the blank (shown in Fig. 2) make a terminal abutment with each other when the blank is bent into shape, and thus constitute bridge 3, which is shown in the remaining figures. In like manner the wings 4 of the blank become the bridge 4 of the stock. Bridge 3 serves as a slightly-yielding and resilient support for the knob 5, which is fastened thereto by means of a screw 6 and nut 7, and in like manner bridge 4 constitutes a similar seat for the handle 8, which is secured thereto by the screws 9 and 10 and the screw-plate 11. The frog-seat 12 is firmly secured to the stock in its proper position by pins 13 and dowel 14 and reaches from one flange 2 to the other, as shown in Fig. 3. Neither the frog 15, which is adjustably secured to seat 12 by screws 16, nor the plane-iron 17, the plane-iron cap 18, and the cap 19, all which are exhibited in a familiar form in Fig. 1, require any particular description, as their special form does not affect the essence of my invention.

The described construction of the stock from a single flexible sheet is simple and easy in respect of the process of manufacture, and the described mounting of the knob and the handle of the plane upon raised bridges of the stock renders the manipulation of the tool smooth and easy to the hand of the carpenter.

Such being the construction and operation of my improved carpenters’ planes, I claim as my invention —

l. In a plane-stock, a sole, and two flanges bent up respectively from the side edges of the sole, in combination with a transverse bridge, from one of said flanges to the other, all formed from a single piece of sheet metal, substantially as and for the purpose specified.

2. A plane-stock, formed of a single sheet of metal, and consisting of a sole, two flanges bent up respectively from the opposite edges of the sole, and two bridges from one of said flanges to the other, in combination with a knob and a handle which are mounted upon said bridges respectively, substantially as and for the purpose specified.

3. In a plane-stock, a thin sole, and two thin flanges bent up respectively from the side edges of the sole, in combination with a bridge from one of said flanges to the other, all formed from a continuous piece of sheet metal, and provided with a knob or handle which is mounted upon said bridge, substantially as and for the purpose specified.

4. A plane-stock, formed from a single sheet of metal, stamped out, and consisting of a flat sole, two flanges bent up respectively from opposite edges of such sole, and two bridges between said flanges, substantially as and for the purpose specified.

In testimony whereof I hereunto set my name in the presence of two witnesses.

ALBERT E. CHURCH.
