Description
JOINT DEVICE FOR WOOD-HANDLED WOODTURNING TOOLS
FIELD OF THE INVENTION
The present invention relates to the field of wood turning.
BACKGROUND OF THE INVENTION
In the field of wood turning, various tools, such as bowl gouges and spindle gouges, are used for shaping wood.
Historically, woodturning tools included a wooden handle having a recess defined therein at one end; a metal wood-cutting bit fitted in and extending from the recess; and a ferrule fitted around the handle, overlying the recess, to strengthen the end of the handle and prevent splitting therein.
It is known for wood turners to self-manufacture woodturning tools, by assembling purchased wood-cutting bits and purchased ferrules with self-manufactured handles.
This reduces cost to the wood turner, and permits the wood turner to self-manufacture a handle that is customized in terms of shape and wood to his or her liking.
However, proper application of a ferrule to a wooden handle is not an easy task, and is typically facilitated by the use of specialized ferrule clamping equipment, which is not always readily available to wood turners.
Accordingly, specialized handles have been developed, which releasably, securely receive wood-cutting bits. One known handle of this type includes a handpiece having a recess at one end. The recess is adapted to receive a wood-cutting bit, such as a spindle gouge or bowl gouge, such that the wood-cutting bit projects from the recess.
In the handle, a pair of threaded bores are provided, in which are threaded conventional set screws. In use, a wood-cutting bit is fitted in the recess, and the set screws are engaged, to bear against the wood-cutting bit and releasably secure same in position.
This fastening mechanism enables bits to be easily replaced.
These specialized handles render it possible for the wood turner to avoid the costs associated with the purchase of wooden handles and the procurement of specialized ferrule clamping tools. However, these specialized handles are relatively costly, and providing same in a wide variety of shapes and sizes, to meet the specific desires of individual wood turners, would add even further to costs.
SUMMARY OF THE INVENTION
A device for use with a bit and a wooden handle forms one aspect of the invention.
The bit and handle with which this device is used have respective ends. This device comprises a body. The body defines a first recess, a second recess and at least one threaded bore. The first recess receives the end of the bit in use. The second recess securely receives the end of the handle in use. The at least one threaded bore extends from the first recess through the body. This device further comprises a set screw for each threaded bore and threadably engaged therein, in use, to bear against the bit and releasably lock the bit in the first recess, to form a hand tool.
A device for use with an elongate wood-cutting bit and an elongate wooden handle forms another aspect of the invention. The bit and handle with which this device is used have respective ends. This device comprises a body. The body defines a first recess, a second recess and at least one threaded bore. The first recess receives the end of the wood-cutting bit in use. The second recess securely receives the end of the handle in use. The at least one threaded bore extends from the first recess through said body.
This device further comprises a set screw for each threaded bore and threadably engaged therein, in use, to bear against the bit and releasably lock the bit in the first recess, to form a wood-turning tool.
A device for use with an elongate wood-cutting bit and an elongate wooden handle forms another aspect of the invention. The bit with which this device is used has a shank portion and a cutting portion. The handle with which this device is used has a handpiece and a frustoconical end. This device comprises a body defining a first recess, a second recess and at least one threaded bore. The first recess receives the shank portion of the wood-cutting bit in use. The second recess securely receives the end of the handle in use. The at least one threaded bore extends from the first recess through the body. This device further comprises a set screw for each threaded bore and threadably engaged therein, in use, to bear against the bit and releasably lock the bit in the first recess, to form a wood-turning tool.
These devices permit a wood turner to relatively inexpensively self-manufacture a hand tool, having a turned handle that is customized in terms of shape and wood to his or her liking, without the need to press-fit a ferrule. Other advantages, features and characteristics of the present invention, as well as methods of operation and functions of the related elements of the structure, and the combination of parts and economies of manufacture, will become more apparent upon consideration of the following detailed description and the appended claims with reference to the accompanying drawings, the latter being briefly described hereinafter.

DETAILED DESCRIPTION
With reference to FIGURE 1, a preferred embodiment of the present invention, a joint device, is illustrated and is designated by the general reference numeral 20.
The device is shown in use in FIGURE 2 with an elongate wood-cutting bit 22 and a wooden handle 24. The wooden handle 24 has a handpiece 26 and a frustoconical end (not shown). The wood-cutting bit 22 is a gouge, and has a shank portion 28 and a cutting flute portion 30.
With reference to FIGURE 1 through FIGURE 5, the device 20 comprises a brass body 32 and a pair of set screws 34.
The body 32 defines a first cylindrical recess 36, a second frustoconical recess 38 and at least one threaded bore, specifically, two threaded bores 40, each extending from the first recess 36 through the body 32. The first recess 36 and second recess 38 are substantially coaxial, and the bores 40 are axially spaced from one another.
The body 32 defines an interior thread 44 surrounding the second recess 38, In use, as shown in FIGURE 2, the first recess 36 receives the shank portion 28 of the wood-cutting bit 22, the frustoconical end of the handle 24 is disposed in the second recess 38 and securely received by the body 32, by engagement of the thread 44, and the set screws 34 are threadably engaged in the bores 40 to bear against the bit 22 and releasably lock the bit 22 in said first recess 36, to form a wood-turning tool, specifically, a bowl gouge, indicated generally with reference numeral 42 in FIGURE 2.
So as to provide a tight, secure fit between the handle 24 and the device 20, the frustoconical end of handle 24 is preferably shaped so as to taper at the same rate as the thread 44, with a widest end of the frustocone being slightly larger than the minor diameter of the thread 44 at thread start, and the length of the frustocone being about the length of the thread 44 or the recess 38, whichever is longer.
The structure illustrated in FIGURE 1 - FIGURE 5 is a 5/8" device, that is a device intended for use with 5/8" OD bits. FIGURE 6- FIGURE 8 show a'h" device.
FIGURE 9- FIGURE 11 show a 3/8" device. FIGURES 12-14 show a'/a" device.
Structures in FIGURES 6-14 corresponding to structures shown in FIGURES 1-5 are identified with the same number.
It is notable that the structures of FIGURE 9- FIGURE 14 include only a single threaded bore 40, since duplicate bores 40 are not necessary for these devices.
Otherwise, the structures of FIGURES 6-14 are substantially functionally and structurally substantially identical to the structure of FIGURES 1-5, and no further description thereof is viewed as necessary.
Various specifications for these devices are set forth below:

It is to be understood that while but four embodiments of the present invention have been herein shown and described, it will be understood that various changes in size and shape of parts may be made. For example, whereas the joint devices herein are described to be brass, other materials, such as aluminum, could be utilized.
As well, whereas the devices herein are shown to form a bowl gouge, it will be evident that the use of a different bit would produce a different tool. By way of example, only, spindle gouges could equally be formed. As well, whereas various sizes, dimensions and thread arrangements are specified, other sizes, dimensioned and thread arrangements can be utilized. For example, the handle from which the tools described herein are produced is indicated to have a frustoconical end, into which end the device thread cuts during assembly. It is equally possible to utilize a handle with a pre-cut thread, in which event it may be desirable to modify the pitch, spacing and/or shape of the thread surrounding the second recess. Accordingly, the invention should be understood as limited only by the claims appended hereto, purposively construed.
