Abstract

A farriers' rasping tool (4) has a rasp (6) and a handle (7). The handle (7) includes a hand-grip (10) with two opposed tines (9) extending from one end of the hand-grip (10). The handle (7) also has a rasp carrier (8) that is pivotally mounted between the tines (9) by means of pivot-pins (12). The carrier (8) has a socket (11) in it which is dimensioned so that a time (13) of the rasp (6) is a force-fit into it. Pivotal movement of the carrier (8) between the tines (9) results in rotation of the rasp (6) between the position shown in solid outline in figure 3 and the position shown in dotted outline in that figure. This range of pivotal movement is about (15) degrees and readily- released locking pins (which are not shown in the drawings) are used to lock the carrier (8) in either of the positions that are illustrated in figure 3. The hand-grip (10) is placed so that its longitudinal axis is spaced above the plane of the rasp (6) relative to the orientation of the rasp as shown in solid outline in figure 3.

Description

Title
Handle for a farrier's rasp or the like
Field of the invention The present invention relates to the trimming of horses' hooves.
Background of the invention
Traditionally domesticated horses have been shod with metal horseshoes. Presently there is a worldwide revolution - "barefoot trimming" - to de-shoe and transition horses to barefoot. This has huge health benefits for horses in general. With the advent of this so- called barefoot trimming movement there is a need for new tools to adequately maintain horses' hooves as there are major differences between how hooves were maintained traditionally to how they are being shaped today.
The traditional farrier shaped the ground-bearing surface of the hoof to accommodate a metal shoe which meant it was flat. To achieve a flat surface the rasping style was big long swipes across the hoof from heel to toe. The barefoot horses' hooves have a totally different shape as they are based on the shape of wild horses' hooves. The ground bearing surfaces of the wild horses' hooves are arched or concave and the outside edge of the walls of the hoof are rounded. This means to achieve and maintain this shape a totally different trimming style is required and hence the need for a different rasp to basically sculpt the hoof into its required shape
Figure 1 shows a traditional farriers' tool 1 consisting of a farriers' rasp 2 retained in a handle 3. The rasping surface of the rasp 2 is traditionally about 35 centimetres in length and the rasp 2 has a tang (not shown in the drawings) which is inserted into the handle 3 to retain the rasp 2 in place in the handle 3, resulting in the longitudinal axes of the rasp and of the handle being substantially coaxial.
It has been found that the traditional tool such as is shown in figure 1 is not optimal for applying a sculpted edge to a horse hoof, in that some regions of the hoof are difficult to access with such a tool. The difficulties of accessing those regions increases the risk of injury to the farriers' hands, so many farriers now choose to wear gloves. The overall length of the tool is also such that it is difficult for persons of less robust physique to use it conveniently.
When using a traditional rasp such as is shown in figure 1, it is generally necessary for the farrier to use long, sweeping strokes of the rasp when working on the bottom surface of the hoof. This involves gripping the rasp handle with one hand and applying both downward (that is, towards the hoof) and forward force. Depending on the strength of the individual farrier, the farrier may also grip the end of the rasp that is opposite the handle with the other hand. Because of the shape of the traditional rasp handle, the farrier's hand at the "trailing" (handle) end of the stroke is close to the rasping surface of the rasp and the hand is at risk of jamming against the horse hoof at the extreme forward end of the stroke.
It will also be seen from the drawings that a farriers' rasp is a relatively long, narrow, flat bar of steel with teeth (of substantially triangular cross-section) formed on opposed surfaces. One end of the rasp carries a tang which is generally in the shape of an elongated triangle which has been truncated at its sharpest apex. The farriers' rasp is accordingly similar to wood working rasps and to metalworking rasps and files. Accordingly, throughout this description (including the claims) the term "rasp" is used to include references to all such rasps and files in general.
It has been traditional to fix files and rasps into wooden handles by force-fitting the tang into a hole formed in the handle, and usually the adjacent periphery of the handle is reinforced with a metal band known as a ferrule. It will be evident that files and rasps may be fixed to handles by using mechanisms other than tangs. Accordingly, throughout this specification (including the claims) the term "tang" is used to include a reference to any mechanism that is suitable for fixing a rasp or the like to a handle or the like.
Summary of the invention In contrast to traditional rasps and the like, according to one embodiment the present invention provides handle for a farriers' rasp or the like, comprising: a receptacle portion that is adapted to releasably receive a tang of the rasp; and a hand-grip portion that is displaced from a rasping surface of the rasp in a direction that is normal to that rasping surface. It is preferred that the receptacle portion is adapted to releasably receive the tang of the rasp in: a first position in which the longitudinal axis of the plane of the rasping surface of the rasp is substantially parallel to a longitudinal axis of the hand-grip portion; and a second position in which the longitudinal axis of the plane of the rasping surface of the rasp is displaced through an angle towards the longitudinal axis of the handgrip portion.
According to another embodiment, the present invention provides a kit of parts comprising two handles for a farriers' rasp or the like, each handle comprising: a receptacle portion that is adapted to releasably receive a tang of the rasp; and a hand-grip portion that is displaced from a rasping surface of the rasp in a direction that is normal to that rasping surface, in which: in one of the handles, the receptacle portion is adapted to releasably receive the tang of the rasp in a first position in which the longitudinal axis of the plane of the rasping surface of the rasp is substantially parallel to a longitudinal axis of the hand-grip portion; and in the other of the handles, the receptacle portion is adapted to releasably receive the tang of the rasp in a second position in which the longitudinal axis of the plane of the rasping surface of the rasp is displaced through an angle towards the longitudinal axis of the hand-grip portion.
Such a tool makes it easier to work on regions of the hooves that are more difficult to access using the traditional farriers' rasp.
Brief description of the drawings
In order that the invention may be more readily understood, preferred embodiments of it are described with reference to the accompanying drawings in which: figure 1 shows a currently known type of farriers' rasp and handle; figure 2 is a plan view illustrating a preferred embodiment of the present invention; figure 3 is a side-elevational view of the embodiment of figure 2; figure 4 is a cross-sectional view on the line A-A of figure 2; and figures 5 and 6 are side-elevational views illustrating alternative orientations of the embodiment of figure 2.
Description of preferred embodiments of the invention A farriers' rasping tool 4 according to a preferred embodiment of the present invention has a rasp 6 and a handle 7. The handle 7 includes a hand-grip 10 with two opposed tines 9 extending from one end of the hand-grip 10. The handle 7 also has a rasp carrier 8 that is pivotally mounted between the tines 9 by means of pivot-pins 12. The carrier 8 has a socket 11 in it. The socket 11 is dimensioned so that a tine 13 of the rasp 6 is a force-fit into it.
As can be seen from figure 3, pivotal movement of the carrier 8 between the tines 9 results in rotation of the rasp 6 between the position shown in solid outline in figure 3 and the position shown in dotted outline in that figure. According to the embodiment of figure 3, this range of pivotal movement is about 15 degrees and readily-released locking pins (which are not shown in the drawings) are used to lock the carrier 8 in either of the positions that are illustrated in figure 3. Figures 5 and 6 further illustrate the relative positioning of the rasp, with figure 5 corresponding to the position of the rasp that is shown in solid outline in figure 3 and figure 6 corresponding to the position of the rasp that is shown in dotted outline in figure 3.
As can also be seen from figure 3, the hand-grip 10 is placed so that its longitudinal axis is spaced above, and substantially parallel to, the plane of the rasp 6 relative to the orientation of the rasp as shown in solid outline in figure 3. It will be seen, particularly with reference to figure 3 that the lowermost surfaces of the hand-grip 10 (considering the orientation of the tool 4 as shown in figure 3) are accordingly displaced from the lowermost portion 16 of the tool. This displacement in turn results in some clearance between the farrier's fingers and the lowermost portion 16 of the tool 4 when the farrier is gripping the hand-grip 10. It is preferred that displacement of the hand-grip 10 from the plane of the rasp 6 is such that there be at least 10 millimetres spacing clearance between the farriers' fingers and the lowermost portion 16 of the tool. We have found that this can generally be achieved when the longitudinal axis of the hand grip portion is spaced between 20 millimetres and 60 millimetres above (but preferably between 30 millimetres and 50 millimetres above) the plane of the lowermost rasping surface when the rasp is in the first position.
It is preferred that the rasping surfaces of the rasp 6 be about 3.5 centimetres wide and that the rasp 6 be about 22 centimetres long, excluding the tang 13.
According to another preferred embodiment of the invention (which is not illustrated in the drawings) the carrier 8 has two sockets such as socket 11. One of these sockets is orientated so that it retains a rasp 6 in an orientation such as is shown in solid outline in figure 3 and the other socket is orientated so that it retains a rasp 6 in an orientation such as is shown in dotted outline in figure 3. According to this embodiment of the invention, the rasp carrier is not pivotable relative to the handle. Instead of relying on pivotal movement of a rasp carrier to give different orientations of the rasp relative to the handle, the rasp is removed from a first socket (such as 11) and placed into another socket which is at the required angular displacement relative to the first socket.
According to yet another preferred embodiment of the invention (which is not illustrated in the drawings) the pivotal movement of the carrier 8 is continuous and there is a locking mechanism that releasably locks the carrier in any desired position over its range of movement.
The surface of the rasp that is shown as lowermost in figures 3, 5 and 6 has finer teeth than does the surface of the rasp that is shown as uppermost in those figures.
When the present tool is in use, the farrier uses it with the rasp 6 in the orientation that is shown in solid outline in figure 3 to trim the bottom surface of the hoof, applying the rasp surface that is shown as lowermost (that is, the surface that has the finer teeth). The farrier grips the hand-grip 10 with one hand and may also grip the other end of the rasp with the other hand. Long sweeping strokes are then used to work on the heels of the hoof. Because of the clearance that the present invention provides between the farrier's fingers (of the hand gripping the hand-grip 10) those fingers do not jam against the horse hoof if the farrier applies a too-aggressive forward stroke. The displacement of the hand-grip 10 away from the plane of the rasp 6 also enables the farrier to apply greater downwards force on the horse hoof than would normally be the case with the conventional positioning of the hand-grip as is shown at 3 in figure 1.
To scoop the quarters of the hoof and to apply a roll to the toe of the hoof, the farrier moves the rasp 6 into the relative position that is shown in dotted outline in figure 3 and in figure 6 and turns the tool over in the hand. The farrier then applies the surface that is shown as uppermost in figures 3, 5 and 6 (the more coarsely -toothed side of the rasp) to the hoof.
While the present invention has been described with reference to a few specific embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications may occur to those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
"Comprises/comprising" when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
