Detailed description of the invention
A known masonry saw as described in US patent number 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 US patent number 4, 315, 494. As well as US patent number 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 ½(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). .
Figure 5 illustrates a view looking straight down to demonstrate the invention (1) at work, with the usual environment of the invention, showing the bottom of the invention (1) abutting the vertical saw table curb (3) that is reflected by two horizontal phantom lines (3) and extending parallel to the bottom of the invention (1), the top of the invention (1) is shown supporting a piece of tile cap (4) that is depicted by rectangular phantom lines extending inclined to the tile saw table curb (3 ) by a 22 and halve degree (6)angle to the tile saw blade (2) that is depicted by two horizontal solid lines extending perpendicular to the tile saw table curb(3) in a position the blade occupies(8) both before and after making a miter cut on a single peace of the tile cap( 4 ).
In summary the invention uses the elements of simple 45°(7) and 22 1/2 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 Fig. #1 and Fig.#3 for weight and strength. The invention (1), a block like platform, provides a water proof, stable, flat and square surfaces to facilitate miter cuts on a wide variety of masonry products. The simplicity of this system cannot be overstated in regards to speed, safety and accuracy.
