To all whom it may concern:

Be it known that l, WILLIAM E. SPAKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more particularly to a novel construction of sheet metal planes.

Certain features of my improvements are especially applicable to planes of the smaller sizes which are known as pocket planes or toy planes, but the invention is not limited in this particular.

The primary object which I have in view is the provision of a light, handy, efficient and durable plane, in which the number of parts is reduced to a minimum, and which can be readily and cheaply manufactured.

To this and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a plane embodying my improvements, Fig. 2 is a top plan view of the same, Fig. 3 is a section on line 3–3 of Fig. 2, Fig. 11 is a front end elevation of the plane, Fig. 5 is a rear end elevation thereof, Fig. 6 is a section on line 6–6 of Fig. 1, Fig. 7 is a top plan view of the frog, detached, Fig. 8 is a top plan view of the clamp, and Fig. 9 is a bottom plan view of the clamp.

Referring to the drawing, the body or stock 10 is of the usual channeled form and it is preferably constructed of sheet metal. The frog 11 has the usual relation with respect to the throat 12 and said frog is constructed of a sheet metal plate 11a having downturned side portions 11b fitted within and against the side walls of the stock. In order to secure the frog firmly in place in the stock, it is necessary to employ only two fastening members such as the rivets 13, 14. These rivets pass through the extensions 11b of the frog into and through the respective side walls of the stock. It will be noted from a comparison of Figs. 1 and 3 that the rivets 13, 14 are out of line with each other whereby any turning or rotary movement of the frog relatively to the stock is absolutely prevented simply by the use of these two fastening members, one associated with each of the side walls of the stock.

At the rear of the frog the same is provided with integral downturned lugs 15, 16 provided with threaded perforations for the shank 17 of the adjusting screw 18. The cutter or bit 19 is supported on the frog 11 in the usual manner and it is of customary form except for the fact that its rear extremity is provided with a transverse slot 20 to receive the milled head 21 of the adjusting screw 18. The peripheral portion of the head 21 extends through the slot 20 for a slight distance, and as the adjusting screw is turned, the head thereof will turn freely in the slot 20 thereby advancing or retracting the cutter 19 according to the direction in which the screw is rotated. ln other words, the slot 20 in fitting over the head 21 interlocks the cutter and the adjusting screw against relative longitudinal displacement while permitting the rotation of the screw relatively to the cutter.

The frog 11 carries a pivot or stud 22, and the cutter is provided with the usual slot to fit over this stud 22. The clamp 23 consists of a sheet metal plate having downturned edges 24 and a keyhole slot 25 adapted to cooperate with the stud 22 in the usual manner. At the rear extremity of the clamp 23, the same is provided with a threaded socket 26 through which a clamping screw 27 passes into engagement with the upper surface of the cutter or bit. The cooperation between the clamping screw 27, the clamp 23, the stud 22, and the bit 19 is more or less usual and need not be further described.

In order to afford a convenient and handy grip for the workman, the stock is provided at the rear end with a palm rest 28. This consists of an upwardly directed sheet metal plate having a convex rear surface and forwardly extending lugs 29 fitting between and against the side walls of the stock. The palm rest is substantially U-shaped in cross-section, the upper edge 28a being rounded and the lower edge 28b straight and horizontal and fitting snugly against the top surface of the bed of the stock. The lugs or extensions 29 are secured to the side walls of the stock by rivets 30, 31 or similar fastening members. The rivets 30, 31 are offset from each other as in the case of the rivets 13, 14 so that turning movement of the palm rest relatively to the stock is absolutely prevented without the employment of additional fastening means, Preferably, the forwardly and upwardly curved plate 28 forming the palm rest is located at the rear extremity of the plane body or stock, and is spaced from the frog and cutter located at the intermediate part of the stock so that the adjusting screw may be located between the palm rest and cutter. The rear surface of the palm rest curves forwardly in order to fit the palm of the operator, and the form of the palm rest is such that it merges from a shallow U-shaped cross-section near the top into a deeper U-shaped cross section at the bottom where the forwardly directed extensions 29 are provided.

I do not claim herein the combination with a stock having upright side walls, of a frog comprising a sheet metal plate having integral downturned side members secured to the side walls of the stock, and integral downtnrned lugs for the bit adjusting screw, one of said lugs being struck out from the rear edge of the frog, and the other being struck out of an opening at the intermediate portion of the frog, as claimed in my co-pending application, Serial No. 778,083.

Without limiting myself to the construction shown, I claim:

1. In a plane, the combination of a stock having side walls presenting a channeled cross-section, a member fitting within the stock and having side walls abutting the respective first-named walls, and means of connection between each side wall of said member and the adjacent side wall of the stock, said two means of connection being located ont of line with each other; substantially as described.

2. In a plane, the combination of a stock having parallel side walls, a sheet metal member having bent-up extensions at the sides fitting within and against said side walls, and a rivet securing each of said extensions to the corresponding side wall of the stock, said rivets being out of line with each other; substantially as described.

3. In a plane, the combination of a stock having upright side walls, a palm rest composed of a plate resting at its lower edge on the bed of the stock and having forwardly directed extensions or lugs at the sides, and a rivet securing each extension or lug to the respective side walls of the stock, said rivets being out of line with each other; substantially as described.

In witness whereof, I have hereunto set my hand on the 5th day of July, 1913.

To all whom it may concern:

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

This invention relates to metal tool bodies and the process of forming the same. The tool body so formed is designed to provide lightness as far as weight is concerned, with effectiveness of structure and strength to resist load strains under practical working conditions. The parts are so combined and connected that there will be practically no distortion due to load strain, or at least so that distortion is minimized. The tool body so formed is light yet substantial and combines with this desirable quality the further desideratum of rigidity.

For the purpose of illustrating and describing a specific embodiment thereof, I have selected a metal plane, the specific construction of which is described in the following detailed specification, taken in connection with the accompanying drawings which illustrate a preferable embodiment of such a plane body.

In these drawings, — Figure 1 is a plan view of the plane body, parts of the plane being omitted. Fig. 2 is a longitudinal vertical section on the line 2–2 of Fig. 1, portions of the operative parts of the plane being shown to illustrate the purpose of the body structure. Fig. 3 is a plan view of a metal blank from which the outer shell or case of the body is formed. Fig. 4 illustrates the metal blanks from which the inner face of the body is formed, these blanks being subsequently treated to provide the strengthening corrugations and tool seats. Fig. 5 is a detail of construction.

Referring to the drawings by numerals, 1 designates the base or shoe portion of the outer shell slotted at 2 to provide the usual cutter throat. This base is provided with side walls or flanges giving the shell or shoe a channel formation. Preferably this outer shell of the plane body is formed of sheet metal stock which may be bent up from a single blank, such as shown in Fig. 3, to form the side walls or flanges 3 and the base 1. This outer shell by itself will hardly be substantial enough to stand the load strain of actual working conditions. I have provided an inner bracing means for this outer shell which bracing means is designed to carry the operating parts of the tool and take a large portion of the load strain from the outer shell. I preferably form this bracing means also from sheet metal stock.

In Fig. 4, 4 designates a metal blank having laterally extending ears 5, and 6 designates a metal blank of the same width but greater length having similar laterally extending ears 7. The two blanks, before the bending operation about to be described, are each provided with threaded bores 3 therein to receive screws from the handle and other parts of the tool. The first blank 4 is of a width to fit between the side walls 3 of the outer shoe. It is treated in a press or other machine to form longitudinal strengthening corrugations 9 therein and preferably also laterally extending corrugations 10, the blank at the intersection of these corrugations being formed with a raised seat 11 for the hand-knob of the plane to rest upon. At the rear end of the longitudinal corrugation 9 the blank is bent laterally to form an upwardly extending bridge 12, the ears 5 being turned inwardly to rest against the side walls or flanges 3 of the outer shell. It will be understood that the side edges of the formed blank will have a snug fit within the side flanges 3 of the outer shell, and that the ears 5 and the edges of the bridge 12 will likewise abut thereagainst at a point substantially above the base 1. The formed blank 4 will be positioned forwardly of the throat 2 in the outer shell. The blank 6, which is designed to carry the cutter, handle, etc, is positioned to the rear of this cutter throat slot. Its forward edge is struck up to form a raised seat or bridge 13, which may constitute a seat for the plane-frog 14; (Fig. 2), this frog having attaching screws 15 which extend through the apertures 8 and into the threaded bores 16 in a strengthening metal piece or blanking 17, which will be positioned under the seat or bridge 13 and above the upper face of the base 1 of the outer shell. This blanking 17 is preferably previously secured to the seat in a suitable manner, as by riveting, although the welding process hereinafter described may also be employed.The ears 7 of the blank 6 are bent upwardly to abut against the sides 3 of the outer shell at points substantially at the base of said shell. The blank is also treated in a press or other instrumentality to provide it with longitudinally extending corrugations 18 and also preferably with a plurality of transversely extending corrugations 19. Intermediate its ends the corrugation 18 is enlarged and elevated to form the raised seat 20 to which the tool handle 21 may be attached by screws 22 taking into the threaded bores 8 previously formed in the blank. When these formed blanks have been assembled in their proper positions upon the upper face of the base of the outer shell, they are preferably secured thereto and rigidly united therewith by fusing the parts together. The method I preferably employ is known as “spot welding.” This spot welding operation preferably takes place about the outer edges of the formed plates so that these formed plates will be fused to the outer shell at points along the lines of the edges of the plates so as to make the outer shell stiii at the point where the side flanges are bent upwardly therefrom, which would otherwise make the body weak at that point. The ears 5 and 7 are also welded to the side walls and with the raised bridge edges, seats, etc., strengthen the outer shell at points above the bend of the side walls, the fusion of the metal taking place therefore, at both sides of the bend and the inner plates. The spot welding may take place both at the outer edges of the plates 4 and 6 and inwardly of said edges and between the edges and the corrugations. These corrugations materially strengthen the base against distortion through working strain, and as the seats for the tool operating parts are raised, these parts do not contact with the base. Consequently the operating load strain is largely taken by the corrugations which, together vvith the bridges, prevent distortion of the base.

What I claim therefore and desire to secure by Letters Patent is:

1. A plane having a tool body of deformable metal, comprising an outer shell having a base and integral upwardly extending side walls, and an inner plate permanently secured to said ba.se and to said upwardly extending side walls, said inner plate having intersecting longitudinally and laterally extending raised strengthening corrugations formed therein bracing the outer shell against longitudinal and lateral strains, and forming a handle support and securing means.

2. A tool body of deformable metal comprising an outer shell having a base and integral upwardly extending side walls and an inner plate permanently secured to said base and to said upwardly extending side walls, said inner plate having intersecting longitudinally and laterally extending raised strengthening corrugations formed therein and said corrugations being broadened at their intersection to provide a longitudinally and laterally braced seat for a tool operating part, raised above the plane of the base whereby communication of deforming strains from such tool operating part to said base is prevented.

To all whom it may concern:

Be it known that I, WILLIAM E. SPARKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more especially to planes constructed wholly of metal.

One of the primary objects of the invention is to provide a light, strong, durable and inexpensive plane, wherein the stock or frame, the frog, and the clamp for the cutter are constructed of sheet metal. To this end the parts mentioned are of novel form and are combined and assembled in a novel way.

Another object of the invention is the provision of certain improved features of construction in what is known as a low angle block plane, more particularly the mechanism for giving the bit or cutter its lengthwise adjustment, and the location of such adjusting means in such a position that the head of the adjusting screw for the cutter serves as a palm rest when the plane is in use.

However, although my improvements are of particular advantage in low angle block planes and in planes constructed for the most part of sheet metal, certain features will be found advantageous in planes of other types.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

ln the accompanying drawings, Figure 1 is a side elevation of a low angle block plane embodying my improvements, Fig. 2 is a top plan view of the same, Fig. 3 is a section on line 3–3 of Fig. 2, Fig. 4 is a front end elevation of the plane, Fig. 5 is a rear end elevation, Fig. 6 is a fragmentary plan view of the stock with the cutter and clamp removed, Fig. 7 is a section on line 7–7 of Fig. 1, Fig. 8 is a detail bottom view of the frog prior to assembling, Fig. 9 is a detail bottom view of the clamp, and Fig. 10 is a detail section on line 10–10 of Fig. 2.

Referring to the drawings, the stock or body 10 is of the usual channeled section but instead of being constructed of cast metal as customary, it is bent up from sheet metal such as sheet steel. The frog 11 is also constructed of sheet metal and it is given the special form shown in Figs. 3, 6, 7 and 8. The frog comprises a plate 11a provided with integral extensions at opposite sides which are bent downward to form legs 12. Rivets 13 connect these integral sheet metal legs with the side walls of the stock between which the frog is set. The legs 12 are so located relatively to the frog and stock as to give the main part of the frog the required inclination to the horizontal. The legs 12 secure the frog to the stock at the rear end of the frog and the forward end of the frog is secured to the stock by means of a lug 14 struck out from the plate 11a and lying in contact with the upper surface of the bed or sole 15 of the plane. In the form shown the downwardly bent lug 14 of the stock is secured to the bed 15 by spot welding, but of course, a rivet or other fastening member could be used if desired.

At the rear of the frog are two downturned lugs 16, 17 for the adjusting screw 18. The lug 17 is struck out of the plate 11a leaving an opening 17a therein, and the lug 16 extends downwardly from the rear edge of the frog substantially parallel to the lug 17. These lugs are provided with threaded perforations engaged by the shank 19 of the adjusting screw 18. The shank 19 is manipulated by a large head or wheel 20 having a neck 21 and a shoulder or collar 22.

The cutter 23 is positioned on top of the frog 11 in the usual manner with its forward extremity in the throat 24 of the bed or sole. The cutter 23 is provided at its rear under portion with a series of transverse arcuate grooves 25 any one of which is adapted to fit snugly over a portion of the periphery of the shoulder or collar 22 on the adjusting screw 18. This provides for the lengthwise adjustment of the bit or cutter as the adjusting screw is moved forwardly or rearwardly in the lugs 16, 17, as will be understood. The shoulder 22 is free to rotate in the groove 25 in which it engages, but the provision of the grooves form shoulders cooperating with the shoulder 22 in such a manner that the cutter or bit partakes of the lengthwise movement of the adjusting screw.

The clamp 26 like the stock and frog is also constructed of sheet metal. Its strength is considerably increased by forming the same of a sheet metal plate having its edges flanged or downturned, substantially throughout the contour thereof, as indicated at 27. This stiffens and strengthens the clamp considerably and it is also reinforced by an integral rib 28 stamped in the same. The clamp is provided with the usual key-hole slot 29 adapted to fit over the usual headed stud 30 which projects up from the frog between the lug 14 and the opening 17a. At the front of the clamp 26 the downturned edge 27 rests on the upper face of the cutter, and is clamped against the cutter at that point by a screw 31 extending through a threaded opening 32 at the rear end of the clamp and engaging the upper surface of the cutter. The stud 30 acts as a pivot in the usual manner so that as the screw 31 is screwed into its socket, the front and rear portions of the clamp will have the customary binding action on the cutter whereby the latter is securely held in place.

In using the plane, the head 20 of the adjusting screw 18 serves as a palm rest. It will be noted that the diameter of the head 20 is at least approximately equal to the width of the cutter. Moreover, the head 20 projects outward beyond the rear extremity of the cutter and is so located with reference to the stock as to form a comfortable support for the palm of the person using the plane. Usually the forefinger will rest in a socket 33 formed in the upper surface of a button 34 riveted to and extending upward from the forward end of the clamp. By this construction, the plane can be grasped and manipulated in a most convenient and satisfactory manner.

In order to make the head 20 of the adjusting screw 18 serve as an effective and comfortable palm rest, said head is not only made of a diameter approximating the width of the stock, but it is also provided with a convex rear surface adapted to conform to the hand of the operator.

It will be manifest that the construction described provides a light, handy plane, which can be readily and cheaply manufactured and is quite strong and durable.

Without limiting myself to the construction shown, I claim:

1. In a plane, the combination of a stock, a frog in said stock, a cutter supported on said frog, an adjusting screw for adjusting said cutter longitudinally, a head for said adjusting screw at the rear of the cutter, of a diameter approximating the width of the stock, and having a convex rear portion or surface to serve as a palm rest for the operator’s hand, a clamp for securing said cutter on the frog, and a button secured to the front end portion of the clamp at the upper surface thereof, said button having an upper surface adapted to support the forefinger of the operator‘s hand, when the latter is supported on the head of said adjusting screw; substantially as described.

2. In a plane, the combination of a stock, a frog in said stock, a cutter supported on said frog, an adjusting screw for adjusting said cutter longitudinally, a head for said adjusting screw at the rear of the cutter, of a diameter approximating the width of the stock, and having a convex rear portion or surface to serve as a palm rest for the operator’s hand, a clamp for securing said cutter on the frog, and a button secured to the front end portion of the clamp, at the upper surface thereof, said button having a socket at its upper surface adapted to receive and conform to the forefinger of the operator’s hand, when the latter is supported on the head of said adjusting screw; substantially as described.

3. In a plane, the combination of a stock with upright side walls, a frog set in between said side walls, and composed of a sheet metal plate having downturned legs at the rear riveted to said side walls, said plate having at the forward portion thereof a struck-out piece or lug parallel to and resting on the sole plate of the stock, said lug or struck-out piece being welded to said sole plate, parallel lugs integral with said frog at the rear portion thereof, and depending therefrom, a cutter supported on said frog, an adjusting screw for said cutter threaded through said parallel lugs, and a clamp for securing said cutter on the frog; substantially as described.

4. In a plane, the combination with a stock having upright side walls, of a frog comprising a sheet metal plate having integral downturned side members secured to side walls of the stock, and integral down-turned lugs for the bit adjusting screw, one of said lugs being struck out from the rear edge of the frog, and the other being struck out of an opening at the intermediate portion of the frog, an adjusting screw threaded through said lugs, a cutter on the frog adjustable by said adjusting screw, and a clamp to secure the cutter on the frog; substantially as described.

In witness whereof I have hereunto set my hand on the 7th day of July 1913.

To all whom it may concern:

Be it known that I, CHARLES E. MITCHELL, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to planes.

Among the main objects of my invention are to provide a plane construction which is simple, inexpensive, effective, and durable. These objects I attain by the use of a new form and arrangement of parts permitting the employment of wrought or sheet metal in the formation of several of the important elements.

ln the drawings, Figure 1 is a side elevation of a plane embodying my invention. Fig. 2 is a longitudinal section through the same. Fig. 3 is a front elevation. Fig. 4 is a perspective view of a detail. Fig. 5 is a perspective view of another detail. Fig. 6 is a plan view of a blank. Fig. 7 is a perspective view of said blank after it has been partially formed. Fig. 8 is a perspective view of a detail of construction formed from the blank 6, and Fig. 9 is a perspective view of another detail.

The stock — that is, the body — of the plane is preferably formed of sheet metal, in which the bottom portion 1 and the sides or cheek-pieces 2 2 may be formed from a blank of a single thickness of sheet metal of proper shape — for example, such a shape as shown in Fig. 6. In the preferable construction this blank is first bent upwardly or crowned, and the sides are also bent upwardly, so as to give to the blank the shape indicated in Fig. 7. When the bottom or floor 1 is flattened down, it will cause the sides or cheek-pieces 2 2 to converge, so that they will assume practically a vertical position. Manifestly the manipulation of the metal in order to produce the desired form may be modified in various ways. ln practice it is customary to provide a transverse passage in the bottom or floor 1, termed the “throat,” through which the cutting edge of the plane-iron projects in use. The throat 3 is indicated in dotted outline in Fig. 6 and may be formed at any time, either before or after the shaping of the stock.

ln the operation of planes of any considerable size it is customary to use both hands, and to that end two handles are usually employed. ln the drawings, 4 is a rear handle, and 5 is a knob constituting a forward handle. The knob 5 may be carried upon a plate 6, which performs the double function of supporting said knob and of reinforcing and strengthening the fioor of the said stock. This plate 6 is provided, by preference, with an integral angular bend 7 at its rear edge so positioned relatively to the throat 3 as to stand closely in front of the same, as best seen in the sectional view Fig. 2. This angular bend also serves to further stiffen the floor directly adjacent to the throat. The handle 4 is carried by the plate 8, which performs the double function of supporting said handle and of reinforcing the floor 1 to the rear of the throat 3.

9 is a supporting chair or bearing, preferably formed near the forward edge of the plate 9, giving further strength to the parts and performing an additional function — to wit, that of a bearing for the frog 10, against which the plane-iron, hereinafter referred to, is clamped. ln the preferable construction the chair or bearing 9 is so formed that the frog will rest upon the rear portion thereof. The forward end of the frog 10 bears upon the floor 1 or upon an extension of the plate 8, if it is desired to extend said plate close to the throat.

11 is a screw-bolt (any desire d number may be provided) which serves to clamp the frog securely in place upon the two bearings-the floor 1 and the chair 9. The bolt 11 is so positioned that it is intermediate of said bearings and will cause the frog to hug tightly thereon, thus preventing chattering of the parts when in use. The frog 10 supports the plane-iron 12, which is clamped thereto by means of a cap-piece 13, which engages with a cap-screw 14, carried by the frog, said engagement being effected in the usual manner.

17 is a cam carried by the cap-piece 13, the same being of the usual construction and performing the usual function — to wit, putting the parts under such tension as to properly clamp the cap-piece and plane-iron against the frog.

15 is a lever carried by a portion of the frog and operated by an adjusting-nut 16, a portion of the lever engaging the plane-iron, so that by means of the nut 16 said plane-iron may be adjusted accurately in the usual way.

I preferably employ a long plate 11a in place of an ordinary nut to coact with the screw-bolt 11. This is a preferable construction, because usually two screw-bolts are employed, both of which may engage with said plate 11a , which gives abroad bearing against the under side of the angular portion formed in the plate 8.

The plates 6 8 may be secured in place against the floor 1 in any well-known manner. One method of attaching the plates is shown in Fig. 3, in which the sides 2 2, close to the floor 1, may be milled out or undercut, and the edges of the plates 6 8 may be correspondingly beveled to take into said undercut recesses. Thus by making a tight fit the plates 6 8 may be driven tightly into place to reinforce and strengthen the floor. The handles 4 5 may be secured in any desired way; but by preference I secure them by means of rivet-bars 41 and 51, respectively. The heads of said rivet-bars engage in countersunk openings in the plates 8 6, respectively, while nuts 42 52 at the upper ends of said rivet-bars serve to clamp the handles 4 5 thereon, respectively.

Additional clamping devices may be employed-for example, a screw-bolt 43, having a nut 44. By this arrangement it will be observed the superposed parts may be securely fastened to the floor without projecting through the same, thus avoiding any danger of marring the wood upon which the plane is used by reason of any irregular projections from the under side of the plane, the surface of which should be smooth and even.

Various modifications may be made without departing from the spirit and scope of my invention, the essential feature of which is to provide a plane of such a construction that sheet metal may be utilized to form the stock or body portion thereof, which stock or body portion will possess all of the advantages of a cast-metal stock in addition to the advantages inherent in the use of sheet metal. This invention permits the use of comparatively thin sheet metal in forming the stock, since the floor is of duplex construction, giving to it the desirable or necessary thickness and strength.

What I claim is —

1. A plane comprising, a body formed of sheet metal and having a sole portion and integral upturned reinforcing-flanges forming the sides, a reinforcing and strengthening plate secured between the side flanges having a stiffening-rib adjacent the throat and a handle separately formed but secured to said reinforcing-plate.

2. A plane comprising a body portion having a sole and sides of sheet metal integral therewith and reinforcing and strengthening plates secured in place against the top of the sole and between the sides having stiffening-ribs adjacent the throat and handle members for said plates, a frog mounted above one of said plates and means for adjusting said frog.

3.

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.

IMPROVEMENT IN BENCH-PLANES.

Specification forming part of Letters Patent No. 168,431, dated October 5, 1875; application filed June 15, 1875.

_________________

To all whom it may concern:

Be it known that we, JUSTUS A. TRAUT and HENRY RICHARDS, both of New Britain, county of Hartford and State of Connecticut, have jointly invented certain new and useful Improvements in Bench-Planes; and to enable others skilled in the art to make the same we will proceed to describe them, referring to the drawings, in which the same letters indicate like parts in each of the figures.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is an end view taken from the front.

The object of the present invention is to produce a plane with a wrought-metal stock or shell of suitable shape and form to possess all the needed strength and stiffness at the points of greatest strain, and yet be neat and serviceable in all the details and particulars of its construction; and to this end it consists in swaging or stamping said stock or shell from a blank or sheet of wrought metal, properly cut so as to afford strong sides and stiff angles, and in combining therewith a suitable body or filling, all as will now be more fully and particularly set out and explained.

In the accompanying drawings the wrought-metal stock or shell is indicated by the letter a; the wooden portion or filling of the plane is marked by letter b. This metal stock or shell is made from or of a piece of wrought metal, which is first cut according to suitable pattern of proper shape and size.

When thus prepared the same is placed over a die, and forced or compressed into the desired shape by a drop-hammer or power-press, thereby easily producing the desired shapes with rigid corners or angles in the stock or shell.

It will be seen that we prepare this form that the metal on a line with the opening where the cutting-iron is inserted shall be sufficiently wide to make broad and strong sides, wide enough, when shaped as above described, to come nearly or quite to the top of the wood.

The filling of the plane may be fastened or secured thereto in any convenient or usual way. By giving this breadth of metal and this shape to the stock or shell in this manner, and attaching it to the filling as described, the parts may be firmly united, and all tendency of the metal to yield or spring is entirely obviated.

The process of manufacture is very easily carried out, and need not be described any more at length in order to be fully understood by persons skilled in this manufacture.

Hitherto planes have been made with a cast-metal stock or shell, and various shapes and forms of them have been so constructed; but, so far as we have any knowledge of the art, none of these show the particular features now considered novel.

Planes have also been made having iron or steel soles, with flange edges sufficiently high to afford space to fasten them to the wooden sides of the plane; but we do not claim any such.

Having thus described our invention, what we consider new, and desire to secure by Letters Patent, is —

The combination of the wrought-metal stock or shell a, having two broad and strong sides, a a’, with a suitable filling, b, substantially in the manner and for the purposes set forth.
