The most common wet saw consists of a diamond saw blade rotating about a horizontal axis with a reservoir pan being located beneath the saw blade for retaining a Coolant which is continuously pumped from the reservoir onto the saw blade while the saw blade is in use. A sliding platform or table mounts on tracks directly within their resident reservoir providing for moving a work piece underneath the circular saw Blade. Such a construction is shown in U.S. Pat. No. 3,635,206 issued Jan. 18, 1972 to HARCLEROGE. More modern wet saws, especially those with smaller diamond blades, try moving the motor with blade attached over the material to be cut, while leaving the platform stationery. Still, the platform must be kept stationery and flat because of the coolant reservoir directly beneath as in a drip pan. Unlike conventional saws, the sliding tray of most Mason's wet saw cannot be permitted to have any angle adjustments relative to the saw blade. This is required because the mounting tracks, on which the platform slides are, as described above, located directly in the cooling reservoir, which would spill its contents if tipped out of the horizontal plane. Therefore, because the platform is not adjustable, a separate miter guide attachment must be provided on the platform. There are those that do have platforms in which a section can be tilted, primarily, only for cutting a miter on a flat tile edge and are of little to no use in cutting radius or odd shaped masonry products. There exists a need for our quick, safe consistent platform to assist in cutting miters on ceramic radius edge trim tiles. Radius edge trim tiles and caps are frequently used as decorative trim and edge pieces in many modern ceramic and Masonry installations. One of the more difficult challenges a tile mason faces is the consistent cutting of 45 and 22.5 degree angles in order to make smooth joints and transitions around the corners and in other locations, as well as with common decorative trim patterns. This problem is exasperated when using radius tile caps, chair rails, ropes, crowns, base, and many others. These styles are much more difficult to lay on a smooth flat surface to use with a standard table style cutting blade. While substantial art exists for measuring tiled cuts and even for drawing complex angles. This art is often complex and does not address the basic need for 45 and 22.5 degree angles, as well as a holding the tile/radius edge trim pieces to be cut in a quick safe fashion.
The ornamental design for a multi-angle tile saw miter guide as shown in U.S. Pat. D 481,603. Kelly. Shows a block like platform to be used as an accessory to a wet saw in the function of cutting tile V cap. Kelly states, prior art as FTS—150 portable production tile saw and cutting accessories described on page 12 of the Felker full-line products catalog, 11th edition, which may be considered prior art relative to the instant application. www.Felkersaws.com. The design patent makes no mention of dimensions or method and materials of manufacture. This design does not allow for a saw blade guide, allowing the saw blade to cut radius material safely and without harming diamond blade.
Other devices may exist in the art for actual tile cutting but these devices also provide a more complex method for cutting variable angles and involve complex table size components with the concurrent increased expense and increase bulkiness and increased complexity that such matters would provide. Therefore, it can be appreciated that there exists a need in the art for a waterproof, light weight, durable and inexpensive wet saw accessory composed of a material that will not harm the expensive diamond saw blade and of the dimensions best suited the widest variety of materials to be miter cuts on standard tile saws. The plastic “miter block with saw blade guide” will aid in the precise safe, cutting of multiple angles on a wide variety of masonry trim and radius cap pieces. The inventions intended usefulness has evolved over years of necessity and research by trial and error while the inventor worked as a mason in the tile arts.
A known masonry saw as described in U.S. Pat. No. 3,635,206 includes a saw blade (2) rotating about a horizontal axis, a coolant containing reservoir and a sliding platform or table with curb (3). The problems encountered while cutting certain miters are well described in U.S. Pat. No. 4,315,494. As well as U.S. Pat. No. 6,082,723. The present invention dramatically simplifies the problem of miter cutting on radius edged masonry products. While the invention (1) may also be used to cut a wide variety of masonry products, for the purpose of the preferred embodiment, the cutting of ceramic tile V-cap (4), using a standard masonry wet saw will be addressed. One skilled in the art will recognize that many of the functions for cutting a wide variety of miter cuts will be equally applicable to cutting masonry products generally. The tile cap (4) may be placed in any of numerous orientations allowing for various dimensions of the tile cap (4) to be cut at the predefined dimensions by simply aliening the saw guide (5) of the invention with the saw blade (2) then pushing the table with curb (3) and the invention (1) with tile cap (4) forward along table carrying the desired portion of the tile Through the cutting blade (2) at the desired angle either 22.5 (6) or 45 degree (7). The invention (1) is to be made of injection molded plastic so as to not harm the expensive diamond saw blade (2).
In summary the invention uses the elements of simple 45 (7) and 22.5 degree (6) angles separated by a slot known as a saw guide (5) built to the dimensions that would best be used with a standard 10 inch blade (2) tile saw and for cutting common tile cap (4). The invention (1) would be made of injection molded plastic materials that do not harm expensive diamond masonry saw blades (2) and is not affected by the wet conditions of work environment produced by the coolant used by the pre-described tile saws. The invention (1) consists of a hollow body with support ribs as shown in cutaway views
