Abstract

A tile or masonry saw assembly may include a saw, a frame, and a workpiece support. The saw includes a motor operable to turn a blade assembly to cut a workpiece. The frame is operably coupled to the saw to enable the saw to be moved along the frame in a first direction. The workpiece support is operably coupled to the frame to support the workpiece relative to the saw, and to allow the workpiece support to be moved along the frame. The saw assembly further includes a movement assembly via which both movement of the workpiece support and movement of the saw relative to the frame is accomplished, such that a movement of the work piece support along the frame in a second direction is enabled to cause the saw to move along the frame in the first direction which is opposite the second direction.

First claim

The invention claimed is:

1. A tile or masonry saw assembly comprising:
a saw including a motor operable to turn a blade assembly to cut a workpiece;
a frame operably coupled to the saw, the frame comprising a first side, a second side, and an end extending between the first side and the second side;
a workpiece support operably coupled to the frame to support the workpiece relative to the saw and configured to be moved along the frame;
a first rail and a second rail extending along each of the first side and the second side of the frame, the first rail being arranged at a higher elevation than the second rail within the frame; and
a first aperture arranged on the first side of the frame between an end portion of the first side of the frame that extends above and inwardly at least to the first rail and the end of the frame of the saw assembly and a second aperture arranged on the second side of the frame between the end of the first rail and the end of the frame of the saw assembly,
wherein first rollers of a first roller assembly of the workpiece support are configured to be positioned below the first and second apertures to be lifted up through the first and second apertures, and thereafter second rollers of the first roller assembly of the workpiece support are configured to be positioned below the first and second apertures to be lifted up through the first and second apertures to remove the workpiece support from the frame.

2. The saw assembly of claim 1 , wherein a support arm of the saw is fixed to the frame.

3. The saw assembly of claim 1 , wherein a support arm of the saw is movable along the frame.

4. The saw assembly of claim 1 , wherein a movement of the work piece support along the frame in a first direction is configured to cause the saw to move along the frame in a second direction which is opposite the first direction.

5. The saw assembly of claim 1 , wherein the workpiece support is coupled to the first rail of each of the first side and the second side of the frame via the first roller assembly, and wherein a support arm of the saw is coupled to the second rail of each of the first side and the second side of the frame via a second roller assembly.

6. The saw assembly of claim 5 , wherein the first rail inhibits upward and downward movement of the first roller assembly, and the second rail inhibits upward and downward movement of the second roller assembly.

7. The saw assembly of claim 5 , wherein a first movable pulley and a second movable pulley, respectively, are coupled to the support arm, the first and second movable pulleys being operably coupled to a flexible coupling member.

8. The saw assembly of claim 7 , wherein the workpiece support is removably attached to the flexible coupling member.

9. The saw assembly of claim 8 , wherein the workpiece support is operably coupled to the flexible coupling member via a clamp that provides removable attachment between the workpiece support and the flexible coupling member.

10. The saw assembly of claim 9 , wherein the clamp is enabled to be loosened relative to the flexible coupling member to enable the workpiece support to be lifted from the frame via the first and second apertures.

11. The saw assembly of claim 1 , wherein the first rollers of the first roller assembly are disposed at a first end of the workpiece support and the second rollers of the first roller assembly are disposed at a second end of the workpiece support.

12. The saw assembly of claim 11 , wherein the second rollers are removable from the first rail at the first and second apertures in sequence after the first rollers have been removed from the first rail at the first and second apertures.

13. The saw assembly of claim 1 , wherein the workpiece support is disposed in a first plane while being moved along the frame, wherein the first and second rollers move in a second plane parallel to the first plane while the workpiece is moved along the frame, and wherein the first and second apertures are disposed above the first and second rollers.

14. The saw assembly of claim 13 , wherein the first and second apertures are disposed below the first plane and above the second plane.

15. The saw assembly of claim 13 , wherein an axis of rotation of the first and second rollers extends parallel to the first and second planes.
