A scraper is mountable on a snow removing machine for scraping snow on a road surface. The scraper has a polygonal prism member rotatably mountable to a lower end portion of a snow removing plate of a snow removing machine. The polygonal prism member has a first end, a second end disposed opposite the first end, surfaces disposed between the first and second ends, and a central hole extending throughout a length of the polygonal prism member from the first end to the second end. The scraper also has blades each removably connected to respective ones of the surfaces of the polygonal prism member. A rotation prevention device has a pair of rotation prevention members for preventing rotation of the polygonal prism member. Each of the rotation prevention members has a plate disposed on a respective one of the first and second ends of the polygonal prism member and fixedly mountable to the snow removing plate, a support shaft extending through the central hole of the polygonal prism member and connected to the polygonal prism member for rotation therewith, and a lock member for releasably locking the plate and the support shaft to one another to prevent rotation of the polygonal prism member.

An improved tile spacer as recited in claim 11, wherein said at least first groove is configured to have a width that is narrower than the width of said spacer arms. 14. An improved tile spacer as recited in claim 11, further comprising a second groove established within the flat bottom surface of said spacer body. 15. An improved tile spacer as recited in claim 14, wherein said spacer body defines a center within which said first groove intersects said second groove at substantially the center of said spacer body. 16. An improved tile spacer as recited in claim 15, wherein said first groove intersects said second groove to form a cross-shaped groove that is radially offset from said interconnected spacer arms of said spacer body by an angle of approximately forty five degrees. 17. An improved tile spacer as recited in claim 11, wherein said at least first groove is substantially configured having a "v" shaped cross section. 18. An improved tile spacer as recited in claim 11, wherein said at least first groove is substantially configured having a "u" shaped cross section. 19. An improved tile spacer as recited in claim 11, further comprising a concavity at the intersection of said interconnected spacer arms. 20. A tile spacer for maintaining spacing between corners of adjacent tiles during installation, comprising: a spacer body having extended spacer arms; a substantially flat bottom surface established by the spacer body; and means for establishing a raised bead of adhesive between the corners of the tiles. 21. A tile spacer as recited in claim 20, wherein said means for establishing said raised bead of adhesive comprises: at least a first groove established within said flat bottom surface of said spacer body. 22. A tile spacer as recited in claim 21, wherein said means for establishing said raised bead of adhesive further comprises: at least a second groove established within said flat bottom surface. 23. A tile spacer as recited in claim 22, wherein said spacer body defines a center and said first groove intersects said second groove at substantially the center of said spacer body. 24. A tile spacer as recited in claim 23, wherein said first groove intersects said second groove to form a cross-shaped groove that is radially offset from the extended arms of said spacer body by an angle of approximately forty five degrees. 25. A tile spacer as recited in claim 23, further comprising: a handle extending from said spacer body from a side opposite said first and second grooves. 26. A tile spacer as recited in claim 20, wherein said at least first groove is substantially configured in a "v" shaped cross section. 27. A tile spacer as recited in claim 20, wherein said at least first groove is substantially configured in a "u" shaped cross section. 28. A tile spacer as recited in claim 20, further comprising a concavity at the intersection of said spacer arms within said spacer body. 29. A tile spacer, comprising: a spacer body having extended spacer arms; a substantially flat bottom surface established by said spacer body; and at least a first groove established in said bottom surface of said spacer body. 30. A tile spacer as recited in claim 29, further comprising: at least a second groove established in the bottom surface of the spacer body. 31. A tile spacer as recited in claim 29, wherein the intersection of said extended arms within said spacer body form a cross-shaped spacer having a center in which said first groove intersects said second groove. 32. A tile spacer as recited in claim 31, wherein said first groove intersects said second groove to form a cross-shaped groove that is radially offset from said cross-shaped spacer body by an angle of approximately forty five degrees. 33. A tile spacer as recited in claim 29, further comprising: a handle extending from said spacer body in a direction opposite said bottom surface of said spacer body. 34. A tile spacer as recited in c laim 29, wherein said at least first groove is configured with a "v" shaped cross section. 35. A tile spacer as recited in claim 29, wherein said at least first groove is configured with a "u" shaped cross section. 36. A tile spacer as recited in claim 29, wherein said at least first groove is configured to have a width that is narrower than the width of said extended arms of said spacer body. 37.
