Abstract
A tile saw includes a saw with a cutting blade, a frame supporting the saw, a table supporting a workpiece and being slidable relative to the frame, and a rear fence secured to the table. The rear fence has an engagement surface and is adjustable between an operating position and a bypassed position. The bypassed position includes the engagement surface of the fence being no higher than even with the planar surface of the table to allow a workpiece to extend beyond a rear edge of the table. In the operating position, the engagement surface of the rear fence projects axially from the planar surface of the table to support the workpiece as the workpiece is pushed into the cutting blade during operation. The fence can be adjusted between the operating and bypassed positions by using any one of a cam lever clamp, pin and guideway, or rotatable latch.
Description
TECHNICAL FIELD

This disclosure concerns a tile saw. More particularly, this disclosure relates to a tile saw having an adjustable fence and methods of use.


BACKGROUND

Tile saws are used for cutting workpieces, such as ceramic tile. Typically, tile saws are sized to accommodate up to 8 in×8 in or 12 in×12 in tiles. However, larger tile sheets are now being offered and are popular in the market place.


SUMMARY

In one aspect, a tile saw is provided. The tile saw includes a saw having a cutting blade; a frame supporting the saw; a table having a planar surface configured to support a workpiece, the table being slidable relative to the frame; and a rear fence secured to the table. The rear fence has an engagement surface and is adjustable between an operating position and a bypassed position. The operating position includes the engagement surface of the fence fixed to project upwardly from the planar surface of the table to support the workpiece during a cutting operation. The bypassed position includes the engagement surface of the fence no higher than even with the planar surface of the table to allow a workpiece to extend beyond a rear edge of the table.


In some examples, the engagement surface, when in the operating position, is disposed along a plane that is perpendicular to a plane containing the cutting plane.

DETAILED DESCRIPTION

This disclosure provides a wet tile saw 10 that can be used to accurately and quickly cut construction materials, such as ceramic, marble, or granite tiles, and the like. The wet tile saw 10 employs a lubricant, such as water, to cool a cutting blade 15 and to carry away debris removed during the cutting process. As illustrated in FIG. 1, the wet tile saw 10 includes a saw 20, a table 25, a frame 30, a pan 35, and an extension 40.


The frame 30 is a structural component that includes one or more rails 50 (e.g., a pair of rails) that extend along a longitudinal axis 55 of the tile saw 10, the one or more rails 50 defining a guide. In some embodiments, at least two rails 50 are spaced apart from one another such that they are on opposite sides of the frame 30.


The table 25 may include a substantially planar top surface 95 that is arranged to support a workpiece 135, such as a piece of tile (shown schematically in FIG. 1) to be cut. The workpiece 135 may extend beyond the edges of the table 25 in some embodiments, and include a greatest dimension (e.g., a maximum length, a maximum width, and/or the like) that is at least about 12″ more, at least about 24″ more, at least about 36″ more, and/or the like. The workpiece 135 may include a square shape, a rectangular shape, and/or the like.


The top surface 95 includes a plurality of grooves or slots 100 arranged to direct the liquid coolant and collected cutting debris off the table 25 and into the pan 35. In addition, the table 25 includes multiple slots 105 (e.g., two slots 105, three slots 105, and/or the like) that extend parallel to the saw axis 55 and that are shaped to receive the cutting blade 15 during a cut. A first slot 105a is arranged to receive the blade 15 during a vertical cut and is therefore substantially vertical. A second slot 105b is angled at a first angle, such as 45° from vertical, to receive the saw blade 15 during a bevel cut at the first angle. A third slot 105c is arranged at a second angle, such as 60° from vertical, to receive the saw blade 15 during a bevel cut at the second angle. Additional slots 105 may be provided at different angles, if desired.


The extension 40 is configured to attach to the pan 35, the frame 30, and/or a stand (not shown) and extends beyond the pan 35 behind the saw 20. The extension 40 functions as a water tray 45 and is angled to catch lubricant that splashes in the rearward direction and direct the lubricant back to the pan 35. The water tray 45 is on a side of the saw 20 opposite of the cutting blade 15.


The table 25 may include a rear fence 110. The rear fence 110 is configured to provide support for the workpiece 135 as the workpiece 135 is pushed, or otherwise moved, into the blade 15 during a cutting operation. As is described further below, the rear fence 110 has an engagement surface 115 (FIGS. 3, 6-10, 17, 19, 22, and 23) that is adjustable (e.g., via rotating, pivoting, sliding, and/or the like) between an operating position and a bypassed position (the bypassed position being shown in FIG. 1). The fence 110 is described in detail further below.


The operating position includes the engagement surface 115 of the rear fence 110 fixed to project upward from the planar top surface 95 of the table 25 to support workpiece 135, such as tile, as the workpiece 135 is pushed into the cutting blade 15 during operation. Alternatively, other arrangements can include saws in which the workpiece 135 is stationary, while the blade moves or translates over the workpiece 135. FIGS. 2, 4, 7, 12, 14, 17, and 20 show the engagement surface 115 of the rear fence 110 in the operating position. In the operating position, the table 25 will move along the rails 25 along the axis 55 (FIG. 1) in a direction toward the cutting blade 15, with the engagement surface 115 engaged against (e.g., abutting) the workpiece.


The bypassed position includes the engagement surface 115 of the rear fence 110 no higher than even with the planar top surface 95 of the table 25. That is, in some embodiments the engagement surface 115 of the rear fence 110 may be substantially even with and, thus, substantially planar with the planar top surface 95 of the table 25. In some embodiments, the engagement surface 115 of the rear fence 110 may be lower than and non-planar with the planar top surface 95 of the table 25. This layout allows the workpiece 135 to extend beyond a rear edge 125 (FIG. 1) of the table 25. In this way, larger workpieces 135 may be accommodated for cutting by the saw 20. In FIG. 1, the workpiece 135, shown schematically, extends beyond the rear edge 125 of the table 25. This position of the workpiece 135 is possible because the engagement surface 115 does not extend higher than the planar top surface 95 of the table 25. The bypassed position is shown in FIGS. 1, 3, 5, 6, 8, 9, 13, 15, 18, and 21.


When the engagement surface 115 of the rear fence 110 is in the bypass position, a rip guide 145 (FIG. 1) having an engagement surface 146 parallel to the plane of the cutting blade 115 and the axis 55 is used to abut against an edge of the workpiece 135. The position of the rip guide 145 is adjustable, and can be selectively moved or translated or slid by the user into an abutting engagement against an edge of the workpiece 135,


When the engagement surface 115 of the rear fence 110 is in the bypassed position, the table 25 may be fixed relative to the frame 30. The workpiece 135 may be moved into the cutting blade 15 by the user pushing the workpiece 135 across the top surface 95 of the table 25 and into the cutting blade 15.


1. The Embodiment of FIGS. 2-11

Attention is now directed to the first embodiment of the rear fence 110 shown in FIGS. 2-11. In this embodiment, the rear fence 110 is pivotable between the operating position and the bypassed position. FIG. 2 shows the rear fence 110 in the operating position. The engagement surface 115 is contained within a plane perpendicular to a plane containing the cutting blade 15.


The rear fence 110 is pivotable about a hinge point 155. When the rear fence 110 is pivoted from the operating position to the bypassed position, the engagement surface 115 is in a same plane, or a plane no higher than the planar surface 95 of the table 25. FIG. 9 shows a cross-sectional view of the table 25 with the rear fence 110 in the bypassed position. In the example embodiment, the engagement surface 115 is in the same plane as the planar surface 95 of the table 25. In other embodiments, the engagement surface 115 can be in a plane parallel to, or substantially parallel (i.e., within about +/−10° of being parallel) to the planar surface 95 of the table, and be lower than the top surface 95.


Still in reference to FIGS. 2-11, the tile saw 10 includes a latch arrangement 160 to selectively hold the rear fence 110 in the operating position and release the rear fence 110 to the bypassed position. Many embodiments are possible. In the one shown, the latch arrangement 110 includes a rotatable latch 165. The rotatable latch 165 includes a handle 170 (FIG. 11). The handle 170 can be used to rotate the wall 175, which varies in height. The rotatable latch 165 is secured using mount 180 to the rear fence 110 at latch location 185 (FIG. 10). A keeper 190 is integral with a rear portion or face 195 (FIG. 10) of the table 25. In use, the latch 165 is in the locked or latched position (FIG. 2) with the keeper 190 extending over the wall 175 of the latch 165. When it is desired to move the rear fence 110 into the bypass position, the handle 170 may be rotated within a plane generally parallel to the engagement surface 115. This moves the locking portion of the wall 175 from engagement with the keeper 190. This then releases the rear fence 110 and allows the rear fence 110 to pivot about the hinge point 155 for positioning the engagement surface 115 into the bypass position.


2. The Embodiment of FIGS. 12-19

Reference is now made to the embodiment of FIGS. 12-19. In this embodiment, the rear fence 110 is slidable and, thus, linearly translatable between the operating position (FIGS. 12, 14, and 17) and the bypassed position (FIGS. 13, 15, and 18.)


The engagement surface 115 of the rear fence 110 remains perpendicular, or substantially perpendicular (i.e., within about +/−15° of being perpendicular), to the planar top surface 95 of the table 25, when in both the operating position and the bypassed position. The engagement surface 115 is also within a plane that is perpendicular, or substantially perpendicular, to the plane containing the cutting blade 15. The engagement surface 115 is adjustable between the operating position and the bypass position by a pin and guideway arrangement 200. The pin and guideway arrangement 200 selectively holds the rear fence 110 in the operating position and releases the rear fence 110 to the bypassed position.


Many embodiments are possible. In the embodiment shown, the pin and guideway arrangement 200 includes a guideway 205 (FIGS. 17-19) defined within the fence 110. A knobbed pin 210 is adjustable within the guideway 205 to selectively fix the rear fence 110 in one of the operating position and bypassed position.


The knobbed pin 210 includes a threaded section 215 (FIG. 19) and a turn knob 220. The guideway 205 is shaped so that the pin 210 can be moved therewithin, and the end of the pin 210 can be positioned within an aperture 225 along the rear face 195 of the table 25.


In use, when the user desires to move the rear fence 110 from the operating position to the bypass position, the user may rotate the knob 220 in a direction away from the rear fence 110. This allows the pin 210 to be moved within the guideway 205 from the operating position of FIG. 17 to the bypass position of FIG. 18. The knob 220 can then be rotated in a direction toward the rear fence 110 to tighten the knob 220 against the fence 110 and secure the pin 210 in its position in the guideway 205 and within the aperture 225.


3. The Embodiment of FIGS. 20-23

Reference is now made to the embodiment of FIGS. 20-23. In this embodiment, the rear fence 110 is slidable between the operating position (FIG. 20) and the bypassed position (FIG. 21).


The engagement surface 115 of the rear fence 110 remains perpendicular to the planar top surface 95 of the table 25, when in both the operating position and the bypassed position. The engagement surface 115 is also within a plane that is perpendicular to the plane containing the cutting blade 15. The engagement surface 115 is adjustable between the operating position and the bypass position by a pin and guideway arrangement 300. The pin and guideway arrangement 300 selectively holds the rear fence 110 in the operating position and releases the rear fence 110 to the bypassed position.


Many embodiments are possible. In the embodiment shown, the pin and guideway arrangement 300 includes a guideway 301 embodied as at least a first elongated through slot 305 defined by the fence 110. The slot 305 has a longitudinal axis 306 (FIG. 23) perpendicular to a plane containing the planar top surface 95 of the table 25. A pin 310 includes a first threaded bolt 312 secured to the table 25 and has a first turn knob 320 threadably connected to the first bolt 312. The slot 305 is movable about the pin 310 to selectively fix the rear fence 110 in one of the operating position and bypassed position.


While only a single pin and guideway arrangement 300 can be used, in the embodiment shown, there may additionally be a second elongated through slot 330 and a second threaded bolt 332 with a second turn knob 334, functioning the same as the first slot 305, first bolt 312, and first turn knob 320.


In accordance with principles of this disclosure, the tile saw 10 may additionally include a spring and detent arrangement 340 for holding the fence 110 in the selected operating position or bypassed position. The spring and detent arrangement 340 includes at least one spring 342 secured to either one of the fence 110 and a rear face 195 of the table 25, and at least one detent arrangement 344 positioned to engage the spring 342 defined by the other of the fence 110 and rear face 195 of the table 25.


In the embodiment shown, the at least one spring 342 comprises a leaf spring 346 secured to the rear face 195 of the table 25 and positioned to engage the detent arrangement 344 defined by the fence 110 along the same surface as the engagement surface 115. While only a single spring and detent arrangement 340 can be used, there may be two springs 342, 343, each being a leaf spring secured to the rear face 195 of the table 25, and two detent arrangements 344, 345.


Attention is directed to FIG. 23, which shows an enlarged view of the detent arrangement 344. The detent arrangement 345 is structured the same as arrangement 344. The detent arrangement 344 includes an upper detent 350 and a lower detent 352 with a slide surface 354 therebetween. Spring 342 slides between the upper detent 350 and lower detent 352 to hold the fence 110 in the selected bypassed position (FIG. 21) and operating position (FIG. 20) while the turn knobs 320, 334 are retightened.


In use, when the user desires to move the rear fence 110 from the operating position to the bypass position, the user may rotate the knobs 320, 334 in a direction away from the rear fence 110. This allows the fence 110 to be moved vertically so that the slots 305, 330 move about the bolts 312, 332 from the operating position of FIG. 20 to the bypass position of FIG. 21. This also includes moving the fence 110 against the springs 342, 343 and between the lower detents 352 and upper detents 350. The knobs 320, 334 can then be rotated in a direction toward the rear fence 110 to tighten the knobs 320, 334 against the fence 110.


4. The Embodiment of FIGS. 24-28

Reference is now made to the embodiment of FIGS. 24-28. In this embodiment, the rear fence 110 is slidable between the operating position (FIG. 25) and the bypassed position (FIG. 24). In particular, the rear fence 110 is slidable in an axial direction relative to the table 25 between the operating position and bypassed position. By “axial direction,” it meant that the fence 110 is slidable within a plane orthogonal to a plane containing the table 25. See arrow 405 in FIG. 25 showing the direction of motion of the fence 110.


The engagement surface 115 of the rear fence 110 remains perpendicular, or substantially perpendicular, to the planar top surface 95 of the table 25, when in both the operating position and the bypassed position. The engagement surface 115 is also within a plane that is perpendicular to the plane containing the cutting blade 15. In this embodiment, the engagement surface 115 is adjustable between the operating position and the bypass position by a clamp arrangement 400. The clamp arrangement 400 selectively holds the rear fence 110 in the selected position of either the operating position or the bypassed position.


Many embodiments are possible. In the embodiment shown, the clamp arrangement 400 includes a pair of cam lever clamps 402, 403. Each cam lever clamp 402, 403 includes a pivot lever 404 with a handle 406 a cam head 408. The handle 406 is sized to be gripped by a human hand and can be used to pivot the pivot lever 404 between a locked position and an unlocked position. In this embodiment, the locked position has the handle 406 adjacent and generally parallel to the fence 110 (FIG. 24), while the unlocked position has the handle 406 generally perpendicular to the fence 110 (FIG. 25).



FIG. 24 shows pivot arrows 410 indicating the direction of pivot from the locked position to the unlocked position, while FIG. 25 shows pivot arrows 412 indicating the direction of pivot from the unlocked position to the locked position. While FIG. 25 shows the fence 110 in the operating position and with the handles 406 in the unlocked position, it should be understood that after adjusting the fence 110 to the operating position, the pivot lever 404 would be pivoted into the locked position (handles 406 adjacent to the fence 110) to lock the fence 110 in the operating position.



FIGS. 26-28 show further details of the example clamp arrangement 400. The pivot lever 404 is secured to a bolt 414 that is biased by a spring 416. The bolt 414 extends through the rear fence 110 and is movable along a vertically extending guide slot 422 (FIG. 28) in the rear fence 110. The bolt 414 extends into the rear face 195 of the table 25. A nut 418 is securable on an end of the bolt 414 to keep the bolt attached to the table 25. Also visible in FIGS. 26 and 27 is a washer 420 between the cam head 408 and the bolt 414, and a lock washer 424 against the fence 110. While only the cam lever clamp 402 is shown in FIGS. 27 and 28, it should be understood that the assembly for the cam lever clamp 403 is the same.


In use, when the user desires to move the rear fence 110 from the operating position to the bypass position, the user may pivot the pivot lever 404 by gripping the handles 406 and moving in the direction of arrows 410 from the locked position to the unlocked position. This motion rotates the cam head 408, which loosens the clamping force between the table 25 and the fence 110. Loosening of the clamping force allows the fence 110 to be moved vertically from the operating position of FIG. 25 to the bypass position of FIG. 24. This also includes moving the guide slots 422 in the fence 110 along the bolts 414. The pivot lever 404 can then be pivoted back into the locked position in the direction of arrows 412 to lock the fence 110 into the bypass position.


When the user desires to move the rear fence 110 from the bypass position to the operating position, the user pivots the pivot lever 404 in the direction of arrows 410 from the locked position to the unlocked position, which loosens the clamping force between the table 25 and the fence 110 and allows the fence 110 to be moved vertically from the bypass position of FIG. 24 to the operating position of FIG. 25. After adjusting the fence 110 to the operating position, the pivot lever 404 can then be pivoted back into the locked position in the direction of arrows 412 to lock the fence 110 into the operating position.


5. Methods

The tile saw 110 can be used in a method of adjusting the tile saw 110 to accommodate a long length of tile. The method includes providing saw 20 having cutting blade 15. The frame 30 supports the saw 20. Table 25 has planar surface 95 configured to the support the workpiece 135, which can be tile. Rear fence 110 is secured to the table 25. The method includes the step of adjusting the rear fence 110 from the operating position to the bypassed position by moving the engagement surface 115 to a position no higher than even with the planar surface 95 of the table 25 to allow the workpiece 135, such as tile, to extend beyond the rear edge 125 of the table 25.


The step of adjusting the rear fence 110 may include pivoting the rear fence 110 between the operating position and bypass position.
