To all whom it may concern:

Be it known that I, JOHN M. DODENHOF a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to planes for dove-tailing tongue and grooving, dado work and the like, and the primary object of the invention is to provide an improved attachment for planes of this character, which is so constructed that dove tail tongue and grooving can be cut at any angle in an expeditious and simple manner.

Another object of the present invention is to provide an improved guide for dove tail tongue and grooving work and the like, which will hold the plane and its cutting blade at the correct and desired angle, the guide being so arranged and associated with the main stock of the plane in such a manner as to permit the same to be swung at any angle and at any distance from the main stock.

A still further object of the invention is to provide an improved sliding section for the main stock of the plane, so as to permit various sizes and shapes of cutting blades to be used with the plane, the sliding section being formed in separate pieces which are adjustable toward and away from the work, and toward the main stock.

A still further object of the invention is to provide an improved attachment for planes of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market and associated witii planes at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of the improved plane showing the same in use, the work being shown in longitudinal section.

Fig. 2 is a top plan view of the plane and its attachment.

Fig. 3 is a front elevation of the plane and its attachment showing the use of the same for making dove tail grooves, the work being shown in transverse section.

Fig. 4 is a fragmentary side elevation of the plane and attachment looking in the opposite direction from Fig. 1, illustrating the position of the plane and attachment when in use, the work being shown in section, and

Fig. 5 is a detail transverse section taken through the main stock and sliding section illustrating the means of adjustably connecting the sliding section with the main stock.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the plane, B, its sliding section, and C, the improved adjustable guide therefor.

The plane A may be of the usual or any preferred form and of any desired make, or of the type utilized for making dove tails, tongue and grooving, dado work and the like. As shown the plane A includes the main stock 10 having the handle 11 arranged on one end of the same. The main stock 10 is provided with the usual cutting blade or tool guide 12 for the tool or blade 13. As shown the guide is arranged at an angle to the vertical in the usual manner and is provided with the usual holding blade nut and bolt 14’. As shown the bolt extends transversely of the stock. The handle 11 supports at its forward end the usual adjusting device 14, which may be of any preferred construction. The main stock 10 is provided with the straight laterally extending hollow bosses 15, which slidably support the guide arms 16, which are held in their preferred adjusted positions by means of set screws or the like 17. These arms 16 may be of any preferred length and are utilized for supporting the sliding section B and the improved attachment C.

The improved sliding section B of the plane is constructed similar to the usual sliding sections for planes of this character, with the exception that the same is constructed in three sections, namely, the forward body section 20, the rear body section 21 and the connecting bridge piece 22. The body sections 20 and 21 are formed of any preferred material and are in direct vertical alinement with each other and are adapted to receive between the same the cutting blades or tools which are carried by the main stock 10. The forward edge of the body piece 21 of the sliding section B is inclined to conform to the inclination of the guide 12 for the cutting tool or blade.

The bridge piece 22 may be connected to the body sections 20 and 21 in any preferred manner, and if so desired the terminals thereof may be welded or brazed to the body section. As shown the bridge piece 22 is substantially arcuate shaped in plan and is so shaped as to permit blades or cutting tools of various widths to be used. The body pieces 20 and 21 are provided with inclined guide slots 23, which slidably receive the flattened or polygonal shaped terminals 25 of the guide arms 16. It can be seen that the slidin section B may be raised or lowered according to the depth of the groove, tongue or the like being made. To hold the sliding section B in its adjusted position, the flattened or polygonal shaped terminals 25 of the guide arms 16 are provided with threaded bores for the set screws 26 which are adapted to frictionally engage the outer surface of the sliding section B. If so desired the sliding section B may be provided with the swinging spur 27 for cross grain work.

The improved attachment or side section C includes the flat rectangular shaped plate or bottom 28, which is adapted to engage the work and hold the main stock 10 with its cutting blade or tool at the desired angle for making the desired dove tail groove or tongue. The upper surface of the base plate or bottom 28 is provided adjacent to its opposite ends with the upstanding ears 29 which are connected to the lower terminals of the adjusting screw threaded stems 30 by means of pivot ins or the like 31. These screw threaded adjusting stems 30 are slidably carried by blocks 32 which are provided with transverse bores for the reception of the guide arms 16. It can be seen by referring to Fig. 2 of the drawings that the blocks 32 project laterally from the guide arms 16 and are adjustably mounted thereon toward or away from the main stock 10. These blocks are held in their adjusted positions on the guide arms by means of set screws or the like 34. It is to be also noted that not only are the guide arms themselves adjustable but that the blocks 32 are adjustably mounted thereon.

The screw threaded guide stems 30 are, as stated, slidably carried by the blocks 32 and these stems are held in their adjusted positions by means of upper and lower lock nuts 33 which are threaded on the stems into engagement with the opposite sides of the blocks. The lower terminals of the stems 30 are provided with the outwardly extending rigid plates 35, which adjustably support the screw threaded members 36, which are adapted to engage the upper surface of the guide plate or bottom 28 for holding the same at the desired angle in relation to the main stock 10 of the plane A. These screws 36 are held in their adjusted position by means of nuts 37 which are threaded thereon into engagement with the plates 35.

In operation of the plane and guide, the desired tool or cutting blade is placed in the guide 12 in the usual manner and the blade or tool is adjusted by means of the device 14. The sliding section B is then adjusted toward the blade by means of the sliding arms 16 until the section is at the desired point. The guide plate or bottom 28 is then slid on the guide arms 16 to the desired point and held in place by means of the set screws 34 provided for that purpose, after which the plate or bottom 28 is swung to the desired angle at which the dove tail grooves or tongues are to be made on the pivot pins 31, after which the set screws 36 are adjusted so as to hold the plates or bottoms in this position. The plate or bottom engaging the work will effectively hold the main stock 10 and its cutting blade at the desired angle and the dove tail will be made with the desired inclination to the walls thereof. The depth of the groove to be made can be determined by the distance on the plate 28 from the tool and this distance can be varied as desired by means of the threaded stem 30. If so desired, the position of the plate 28 can be changed from one side to the other to suit varying conditions.

The plane, if so desired, can also be used with the usual sliding section and fence (not shown) for rabbeting or the like, but the same forms no part of this invention.

Changes in details may be made without departing from the spirit or scope of this invention; but, I claim:

1. In a plane, the combination with a main stock, a sliding section adjustably carried by the main stock and arranged in parallel relation to the main stock, a cutting blade arranged between the sliding section and the main stock, of a guide including a laterally projecting pivoted plate arranged to turn both in a plane at right angles to the stock and in a plane parallel to the stock and sliding section, and means for varying the angle of the plate in relation to the main stock, sliding section and blade.

2. In a plane, the combination with a main stock, a sliding section adjustably carried by the main stock and arranged in spaced parallel relation thereto, a cutting blade arranged between the main stock and sliding section, of a guide including a laterally projecting plate adjustably toward and away from the main stock, means pivotally securing the plate in position to permit the same to turn both in a lane at right angles to the stock and sliding section and in a plane parallel to the stock and section, means for raising and lowering the plate in relation to the stock, and means for varying the angle of the plate in relation to the stock.

3. In a plane, the combination with a main stock, a sliding section adjustably carried by the main stock, a cutting blade arranged between the main stock and sliding section, of a guide including a laterally projecting substantially rectangular shaped plate, means pivotally securing the plate in position to permit the same to turn both in a plane parallel to the stock and sliding section and in a plane at an angle to the stock and sliding section, means for adjusting the height of the plate in relation to the main stock, sliding section and blade, and means for varying the angle of the plate in relation to the stock.

4. In a plane, the combination with a main stock, a pair of sliding guide arms carried by the stock, means for holding the guide arms in adjusted position, a sliding section adjustably carried by the guide arm, means for holding the sliding section in adjusted position, a cutting blade arranged intermediate the sliding section and main stock, of a guide including a pair of blocks adjustably mounted on the guide arm, threaded stems slidably carried by the blocks, means for holding the threaded stems in adjusted position in relation to the blocks, a substantially rectangular shaped flat plate pivotally carried by the lower ends of the stems, and means for holding the plate in adjusted position in relation to the stems.

5. As a new article of manufacture, a guide for bench planes comprising a flat plate, a pair of pivoted stems carried by the upper surface of the plate, blocks adjustably carried by the stems, means for holding the stems and the blocks in adjusted relation to each other, laterally projecting plates rigidly carried by the stems adjacent to their lower ends, adjustable set screws carried by the laterally projecting plates arranged to engage the upper surface of the first mentioned plate, the blocks having transversely extending bores therein, and set screws carried by the blocks arranged to extend into said bores.

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 Iinprovements in Dovetail Tongue and Groove Cutters, of which the following is a full, clear, and exact description.

My invention relates to an improved means in the nature of a plane for forming dovetailed or undercut tongues and grooves.

The object of the invention is to provide a means for performing the above function which shall be so constructed as to permit the forming of such tongues or grooves with the greatest facility and accuracy.

In the drawings, Figure 1 is a side elevation of the tool assembled and adjusted for the purpose of forming an undercut groove. Fig. 2 is a rear end elevation of Fig. 1, showing the tool as it appears in the act of forming a groove. Fig. 3 is an end elevation of the tool assembled and adjusted for the purpose of cutting a tongue. Fig. 4 is a side elevation of the main body and certain parts on a somewhat reduced scale. Fig. 5 is a view of the reverse side of the parts shown in Fig. 4. Fig. 6 is a sectional view on the line x–x of the Fig. 4, looking in the direction of the arrow. Fig. 7 is a side elevation of a guide frame, arranged for association with the main body of the plane. Fig. 8 is an end view of the guide frame shown in Fig. 7. Fig. 9 is a side elevation of a detail. Fig. 10 illustrates another detail in diderent positions. Fig. 11 is a side elevation of another guide frame arranged for association with the main body of the plane. Fig. 12 illustrates three different sizes of plane irons, on the scale indicated in Fig. 4. Fig. 13 is a side elevation of a detachable spur carrier.

1 is the main body or cutter carrier of the tool, the same being provided with a handle 1a and with a long narrow sole 1b.

2 is a cutter or plane iron, the cutting edge of the same being adjustable in a throat in the sole 1b.

3 is a clearance outlet for shavings or chips and located above the aforesaid throat.

4 is a clamp screw for locking the cutter in various positions of adjustment.

The cutter is located in a channel arranged obliquely in the side of the main body 1.

5 is a clutch operated by screw 4, for wedging down upon the cutter 2 when the latter is in position to prevent its unintentional or accidental dislodgment.

The oblique channel for receiving the plane iron is so arranged as to support the upper and lower surface of the shank of the cutter, the lower side of that part of the cutter opposite the recess 3 being supported on the incline 6. As will later be seen, cutters having cutting edges of different widths may be substituted, but to secure the best results the shank portion of each cutter should be substantially alike, the variations in sizes occurring at and directly above the cutting edge.

As will be seen by Figs. 2 and 3, the sole 1b of the body 1 is formed at an oblique angle to the opposite side walls thereof and in practice it is obvious that the edge of the cutter should be shaped to correspond.

7–7a are spurs arranged on opposite sides of the main body 1, both spurs being arranged to be projected to any desired degree or to be entirely retracted as desired. The function of said spurs is to score the wood in advance of the cutter 2, whereby, when said tool is used across the grain, the score lines made by the spurs 7–7a will prevent splintering the wood, thereby enabling the cutter 2 to plow out or to cut a clean channel. It should be stated that the width or thickness of the sole edge of the main body 1 is not greater than the minimum width of the smallest channel which it is possible to form.

The foregoing is a general description of the main body or cutter carrier element of the tool.

8 is the main body portion of what I term the composite guide frame, which frame is arranged for association with the cutter carrier 1 for the purpose hereinafter described.

8a is the side flange of the frame 8, said side flange being arranged obliquely to the sole 8b of said frame.

9 is an upright slot in the fiange 8a terminating at its lower end in an opening 9a.

10–10a are bosses, having passages therein at right angles to the sole 8b of the guide frame 8.

11–11a are set screws carried by the bosses 10–10a respectively.

12 is a thumb piece arranged to receive the thumb of the operator to facilitate the operation of the tool.

14 is a headed stud carried by the main body of the cutter carrier 1, the shank of said stud standing in the upright slot 9 of the frame 8 when the parts are assembled.

15 is a scale at one side of the slot 9.

16 is a gage arranged to co-act with the scale for the purpose hereinafter described. The gage 16 has a slot 16a. 17 is a set screw passing through slot 16a and into the body of the cutter carrier 1, whereby said gage may be adjusted up and down, said scale facilitating said adjustment.

18–18a are threaded holes arranged fore and aft in the body 1 of the cutter carrier, these threaded holes being arranged to receive the two guide posts, spaced apart properly to register with the sockets 10–10a of the guide 8. One of these guide posts is shown at 19, Fig. 3. These guide posts may be readily applied or removed by simply turning the screw end of each into the threaded openings 18–18a. These guide posts are used only when the tool is asembled for forming a tongue.

It will be observed that the stud 14 is arranged directly above the cutting edge of the plane iron 2, the purpose of this being later seen.

I will now describe the tool as assembled and employed in forming an undercut or dovetail groove. In this connection particular reference is directed to Figs. 1 and 2. In these figures it will be seen that the cutter carrier 1 is combined with the guide frame 8 and it may be assumed that the gage 16 is secured by the screw 17 on the scale 15 at the proper elevation to limit the depth of the cut. The intention now is to form a dove-tail groove in a piece of wood indicated at 20 (Fig. 2). To do this, the location of the groove is determined and a guide cleat 21 is tacked down to said piece of wood in a line parallel to the groove to be formed, and at one side thereof a distance corresponding to the width of the bottom of the sole 8b of the guide frame 8. The tool is then placed in the position indicated in Fig. 2 bearing against the cleat 21 and is moved to and fro until the cutter has descended into the wood 20 to the desired depth determined by stop 16. In forming this cut, both spurs 7–7a should be turned down, particularly if cut is to be made across the grain. The cutter carrier 1, being connected to the guide frame 8 only by the stud 14, may take an oscillating movement relatively to the guide frame 8 and hence may follow any warped portion of the wood in which the cut is being formed. By reason of the location of the stud connection 14 relatively to the cutter 2, the oscillating movement of the carrier relatively to the guide frame will not permit the cutter 2 to descend into any part of the wood 20 more than the amount predetermined by the gage 16. When an oblique groove has been cut as indicated in Fig. 2 the tool is removed and the cleat 21 is taken off and tacked down on the opposite side of the groove as indicated in dotted lines, being spaced apart from the adjacent edge to be of the groove a distance corresponding to the width of the bottom of sole 8a of the guide frame. The instrument is then turned around and operated as first described, the cutter 2 working down in the wood until the balance of the intended dove-tail groove is formed, as indicated in the dotted lines, Fig. 2. In forming this last part of the groove, it is unnecessary to employ the spur 7a which may be turned back into the position shown in Fig. 5, a recess in the said main body 1 receiving the same, so that it will stand flush, the spurs themselves being held in all positions by ordinary machine screws. The spur 7a will be seen to be unnecessary at this time because as the cutter descends, the wood on that side of the plane iron (the side toward the spur 7a) has previously been cut away in forming the first part of the groove, hence no chipping or splintering is possible on that side.

In forming a dove-tail tongue, another adjustment is employed, namely, the right angle guide 22, the same being substituted in the place formerly occupied by the guide 8, which latter is transferred to the opposite side of the frame 1 (as shown in Fig. 3) and mounted upon the posts 19–19, the sole 8b of the said guide 8, being spaced apart from the opposite side of the cutter carrier 1, a distance corresponding to the depth of the tongue to be formed. 23 represents the piece of wood upon which the dove-tail tongue is to be formed, said tongue portion being indicated at 24. The gage 16 is now adjusted on the scale 15 to such a position as to properly limit the descent of the cutter carrier 1. The instrument is placed in the position indicated in the Fig. 3, and moved to and fro. The right angle guide 22 cooperates with the guide 8 in holding the cutter carrier 1 in the proper position to cause the cutter to enter the wood as shown in Fig. 3, in which one-half of the tongue is represented as completed. In performing this work, the guide 8 obviates the use of a batten such as 21, although the latter could be used if desirable. To form the other half of the tongue 24 (indicated by dotted lines), the piece of wood 23 is simply turned over and the tool is used on the opposite surface in the same manner. In the formation of the tongue only one spur need be employed, namely the spur 7.

From the foregoing it will be seen that a dove-tail groove and a tongue of corresponding size and cross section may be formed with the greatest accuracy and ease.

Thus far I have described the device as fitted to produce tongues and grooves of the minimum size. When it is desired to produce a tongue and groove of greater size it is merely necessary to substitute a cutter having a cutting edge of greater width than the thickness of the sole 1b of the cutter carrier. When such wider cutter is employed it is obvious that one edge of the same will project beyond one side edge of the sole 1b, and in such an event, in order to provide a spur adjacent to that edge of the cutter, a supporting spur carrier or spacer 25 may be secured to the adjacent side of the main body 1. An illustration of this spacer 25 with the spur 7a is indicated in Fig. 13 and its construction is too obvious to require detailed description. The spacer 25 may be secured to the main body of the cutter by screws which may screw into threaded openings 27–27, Fig. 4.

28 is a projecting stud or screw head, which is arranged below the stud 14, the width of said screw head 28 being less than the width of the slot 9. This projecting head 28 is preferably employed to prevent unnecessary oscillation of the guides 8–22, relatively to the main body 1 of the plane iron carrier, but obviously it may be dispensed with.

In Fig. 12 I have shown cutters 2, 2a, 2b of three different sizes, said cutters being on a scale adapted to the scale of Figs. 4 and 5.

The frame 8 I have termed a composite guide, since it may be applied to either side of the cutter carrier. While in the drawings the outer edge of the guide 8 is shown as straight to furnish a bearing to parallel the sole of the cutter carrier, obviously this and other features may be modified in a variety of ways, so long as the results described are accomplished by means equivalent to those shown and in substantially the same way.
