Abstract
A device for edging stone which is adapted for attachment to a standard wet stone polisher. The device comprises a plate-like housing for squaring the stone polisher with the edge of the stone surface, means for ejecting water or air onto the stone surface, and stoppers for adjusting the depth that the polisher cuts into the stone.
Description
- The present invention relates to a device for edging stone materials which is adapted for attachment to a rotary stone polishing tool.
- There are a number of tools for cutting, shaping, and polishing stone, granite, marble, and the like (hereinafter collectively referred to as “stone”). One such tool is an edger which generally comprises a rotary shaft adapted for combination to various bits. Edgers are primarily used to shape, finish, and profile the edges of slab stone articles, such as counter tops, using differently shaped bits. The process of edging a piece of rough stone is similar to sanding a rough piece of wood in that smoothing and shaping the edge of the stone requires a number of different bits used in succession beginning with a coarse bit and ending with a smooth bit.
- There are several different kinds and sizes of stone edgers that have been used in the art. One such edger is for shaping the edge of a stone countertop. This edger comprises a housing having an internal electric motor with a bit extending below the surface of the housing. In use, the housing rests on the level counter surface while the motor spins the bit and the user guides the bit along the edge of the counter surface smoothing and shaping the edge of the stone counter. The problem with this type of edger is that the internal motor makes it heavy and difficult to transport and maneuver over the counter surface. Further, the weight of the edger's motor causes friction between the lower surface of the housing and the stone countertop as the device moves across the countertop. The friction can cause scratches in the stone's surface. Another problem with this type of edger is that it is relatively expensive to purchase and maintain because of the many moving parts that comprise the gears and internal motor.
- Another device known in the art that can be used as an edger is called a stone polisher. Stone polishers are known in the art as an essential tool for stone workmen. A stone polisher is a small hand tool comprising a rotating shaft able to combine with various bits for etching, polishing, and cutting slab materials such as stone. Stone polishers can be powered pneumatically, electrically, or by any other suitable means. The problem with using a stone polisher as an edger is that stone polishers do not have housings or other guides for aligning and squaring them with the stone. This makes it difficult to form consistent cuts and profiles in stone edges because the angle of the stone polisher relative to the stone's edge is hard to keep consistent. This can lead to more time spent by the stone workman, which means more expense to finish the stone product.
- Therefore, there is a need for a stone edging device that is light weight, easy to use, easy to align with the stone surface, inexpensive, and provides precise edging on stone substrates.
- The present invention is an edging device that comprises a plate which is adapted for attachment to a standard stone polisher. The plate has a top side and a bottom side. The stone polisher is combined with the plate so that the rotating shaft of the polisher extends downward beyond the plane of the plate bottom side. The plate top side has a handle to aid the user in guiding the device over the stone surface and an inlet port adapted for combining the device to a water or air source. The inlet port is in communication with a plurality of holes on the plate bottom side. The holes are adapted to eject the water or air onto the stone surface. The ejected water or air helps to reduce scratches on the stone that may be caused by the plate.
- The device has several features which help to align the polisher with the stone's edge. First, the plate maintains the bit of the polisher at a consistent and proper angle relative to the stone because the majority of the plate's surface area rests level with respect to the stone's surface. Second, the plate serves to align the elevation of the bit relative to the stone's edge because the polisher and plate are always combined at the same relative height. Third, the plate bottom side comprises stoppers which serve to ensure the rotating bit of the polisher cuts into the stone at a consistent and desired depth.
- In use, after the stone polisher is combined with the plate, and after a bit is combined with the shaft of the stone polisher, the device is moved along the edge of a stone surface causing the polisher's rotating bit to contact the edge of the stone surface. The device of the present invention provides a light weight, easy to use edging tool that is relatively inexpensive since most stone workmen already own a stone polisher.

FIG. 6 is a top view showing the bifurcated ends of the collar and the flange at the lower end of the opening. - The present invention is an edger attachment device for combination with a
standard stone polisher 18. As seen inFIGS. 1 and 2 , the present invention comprises aplate 10 having a top side 10 a and a bottom side 10 b, respectively. In the preferred embodiment, the plate top side 10 a is comprised of metal covering and the plate bottom side 10 b is comprised of plastic because plastic is less likely to scratch the stone'ssurface 22. - As seen in
FIGS. 1 and 4 , theplate 10 comprises anopening 12 for attachment to thestone polisher 18. Thestone polisher 18 is inserted into opening 12 until thepolisher 18 rests againstflange 25 near the bottom of the opening 12. Theflange 25 ensures thestone polisher 18 is combined with theplate 10 at a consistent relative height so that thepolisher 18 can be removed and reattached to theplate 10 in the same position.FIG. 1 shows a first embodiment wherein the opening 12 of theplate 10 is located near a first end of theplate 10. Since the majority of the plate's 10 surface area is located away from theopening 12, theplate 10 counterbalances the weight of thestone polisher 18 and theplate 10 remains level with respect to thestone surface 22. Ahandle 14 is positioned on the top portion of theplate 10 thereby allowing the user to firmly press down on thehandle 14 to ensure that theplate 10 remains level on thestone surface 22 even though thestone polisher 18 is hanging off the edge of thestone surface 22 near theplate 10 first end. -
FIG. 4 shows an alternate embodiment wherein theopening 12 is located near the center portion of theplate 10. This embodiment enables the device to be used on the inside edges of openings cut in stone, such as an opening adapted to receive a sink or other plumbing fixture. In this embodiment, theopening 12 is located near the center of theplate 10 to allow a sufficient surface area of theplate 10 to contact and remain level with thestone surface 22 while thepolisher 18 shapes and edges around the sink opening. As seen inFIG. 4 , this embodiment preferably comprisesmultiple handles 14 for better control of theplate 10. Although not shown inFIG. 4 , the elements and features of the first embodiment shown inFIGS. 1-3 , 5, and 6 may also be used in this center-hole embodiment. - As shown in
FIG. 6 , theopening 12 has acollar 13 with a first and second bifurcatedend ends collar 13, respectively. The bifurcatedends screw 15 that is threaded through both bifurcatedends FIGS. 2 and 3 ) is combined with theplate 10 by inserting thestone polisher 18 into theopening 12. Thescrew 15 is then tightened thereby moving thebifurcated ends collar 13 andcorresponding opening 12. Thecollar 13 tightens around thestone polisher 18 thereby securely combining thepolisher 18 with theplate 10. - In addition to the
flange 25 described above, the device of the present invention has several features for aligning thebit 20 of thepolisher 18 with the stone'sedge 50. First, theplate 10 squares thepolisher 18 to the stone'sedge 50 because a sufficient surface area of theplate 10 contacts thestone surface 22 so that theplate 10 is level with respect to the surface of thestone 22. Thepolisher 18 is inserted into opening 12 as described above so that the polisher'sshaft 30 extends downward at a generally ninety degree angle relative to the plane of theplate 10, thereby making the polisher'sshaft 30 square with respect to the stone'sedge 50. - In addition,
FIGS. 2 and 3 show thestoppers 34 on the bottom side of theplate 10. Thestoppers 34 allow the user to adjust the depth at which thebit 20 cuts into thestone 22. Thestoppers 34 are mounted onto shafts which are movable along the length of theslots 35 so the user can adjust the depth of cut that is made into thestone 22 with thebit 20. Typically, thestoppers 34 are positioned so that they contact the stone'sedge 50 just behind thebit 20. This allows thebit 20 to make contact with the stone'sedge 50 without penetrating too deeply into thestone 22. However, if the stone'sedge 50 is extremely uneven or otherwise not desirable, the user may set thestoppers 34 so thebit 20 is allowed to penetrate more deeply into thestone 22. - In the preferred embodiment, the shafts are bolts which can be hand tightened by
fasteners 36 extending from theslots 35 on the plate top portion 10 a. Thefasteners 36 can be wing nuts, “L” shaped bolts, or any other suitable fastening means. In addition to preventing the user from cutting too deeply into thestone 22, thestoppers 34 also comprise a bearing orrotatable ring 37 which is adapted to rotate. The bearings orring 37 rotates against thestone surface 22 as the user moves the device along the stone'sedge 50 to provide a smooth motion for the device at a consistent stone cutting depth. - As shown in
FIG. 1 , the plate top side 10 a has aninlet port 16 adapted for combining the device to a water or air source. Theinlet port 16 has amain water valve 21 for turning the water or air flow on or off. As shown inFIG. 2 , the plate bottom side 10 b has a plurality ofholes 32 which are in communication with theinlet port 16 for ejecting water and/or air onto thestone surface 22. The plate top side 10 a and plate bottom side 10 b are spaced apart to form a chamber for water to flow through. The ejection of the water or air from theholes 32 allows theplate 10 to glide on a water film or an air pocket formed between the plate bottom side 10 b and thestone surface 22. This helps to reduce scratches on the stone surface that may be caused by theplate 10 as well as expel stone debris out from under theplate 10. - Also in communication with the
water inlet port 16 is anozzle 40 as shown inFIG. 2 . Thenozzle 40 is for ejecting water directly onto thebit 20. Thenozzle 40 has avalve 23 for turning the water flow on or off. Thevalve 23 is preferably located down stream frommain water valve 21 so that water can be supplied to the plurality ofholes 32 by turningmain water valve 21 “on”, whilevalve 23 is turned “off” thereby restricting the flow of water tonozzle 40. Thenozzle 40 receives water from thewater inlet port 16 and expels it onto thebit 20 for cooling thebit 20 and for keeping thebit 20 free from debris. - In an alternate embodiment, water can be received directly into the
stone polisher 18 and expelled through thebit 20, as shown inFIG. 5 . In this embodiment, water is received into thestone polisher 18 then directed through the end of theshaft 30 and intobolt 44.Bolt 44 has anopening 31 in its end for receiving the water.Bolt 44 also has a plurality of holes through which water is expelled toward the inside of thebit 20.Bit 20 also has a plurality of holes through which the water is finally expelled onto thestone surface 22. If water ejection through thebit 20 is not desired, abolt 44 may be used that does not have the plurality of holes. This prevents water from being ejected out of thebit 20 and onto thestone 22 as described in this paragraph. - As shown in
FIG. 5 , thebit 20 is attached to thestone polisher 18 by screwing afastener bolt 44 upward through the center of thebit 20, as is known in the art. Abit adapter 42 is placed between thestone polisher 18 and thebit 20 to place thebit 20 at its proper height. The present invention has no means for adjusting the height of thebit 20 relative to plate 10 other than changing the size of thebit adapter 42. As discussed in the “Background” section of this specification, it is usually necessary to useseveral bits 20 when edging a rough stone surface, beginning with a rough bit and ending with a smooth bit. It is necessary that as the user changes the bits, the successive bits remain at the same height relative to theplate 10 and stone's edge. The system comprises a number ofbit adapters 42 which differ for each different edge profile, such as one adapted for the succession of bull nose bits, one for ogee bits, ect. . . . - In use, the present invention is first combined with a
standard stone polisher 18 by securing thestone polisher 18 to thecollar 13 of theplate 10. Abit 20 is attached to theshaft 30 of thestone polisher 18 and theplate 10 is placed on astone surface 22 which squares thebit 20 with the stone'sedge 50. Thestone polisher 18 is actuated causing thebit 20 to rotate. The user guides theplate 10 along the stone'sedge 50 using thehandle 14. Thestoppers 34 allow thebit 20 to grind and/or polish thestone 22 at a consistent depth with the while rotating as the user moves theplate 10 to allow theplate 10 to move smoothly along the stone'sedge 50. Water or air may be introduced throughport 16 and expelled onto thestone surface 22 throughholes 32, and/or expelled onto the rotatingbit 20 throughnozzle 40.
