A The owners of the new vehicle make a claim against Jack’s insurance policy (they are not injured) and once the vehicle damages have been estimated, the insurance company tells the owner of the new vehicle that the insurance will pay such and such amount.
A The owners of the vehicle believe the value of their insurance claim (diminished value or total loss) is more than the insurance company does. You figure you’ve got at least $10,000 in real damages, but the insurance company is sticking by their number.


The lubricating guide support assembly includes two guide supports each having a bearing surface disposed immediately adjacent opposite sides of the saw plate at a spacing to the cutting area for proper alignment of the saw blade during cutting. A Fill out the form to the right to get our sample demand and make your diminished value demand today!
At least one of the guide supports includes a recessed area containing liquid exposed to the saw plate whereat a thin film of the liquid is applied to the saw plate as it passes by the recessed area during cutting. The guide support assembly is required because the circular saw blades have been reduced to a thickness rendering them incapable of maintaining a generally planar configuration during cutting, thereby making them unsuitable for use without auxiliary side support. The openings are arranged on the saw plate to pass by the recessed area and are dimensioned to receive liquid therein for transport away from the recessed area.
Unfortunately, as saw blade thickness decreases more support must be provided by the bearing surface of the guide support against the saw blade which generates greater friction therebetween. When each opening clears the bearing surfaces of the guide supports the liquid transported therein is distributed to the saw plate and the cutting area including the carbide insert teeth by air turbulence and inertial forces. This increase in friction can lead to excessive heating of the saw blade which, in turn, can ultimately lead to carbide insert teeth breakage, sawing deviation, guide pad wear, and saw blade damage.Further improvements to this saw arrangement were made in the late 1980's. Such a saw blade having a thickness at least as small as 0.080 inches is used to cut lumber from Southern Yellow Pine. In a first improvement, cooling of the saw blade is accelerated by the provision of circumferential air slots throughout the saw body, of which the saw blade disclosed in Carter Jr. Each slot consists of an arc of a circle concentric with the saw body and parallel to the peripheral edge of the saw body.
The common problem of sawdust packing in similar openings formed in a saw body, as disclosed for example in Jansen-Herfeld U.S. Furthermore, unlike the blade disclosed in Jansen-Herfeld, the circular saw blade of Carter Jr.
In this arrangement, the plurality of slots provide a radiator cooling effect that accelerates cooling of the saw blade but the slots fail to reduce any friction generated between the saw body and the bearing surface of the guide supports.In a second, independent improvement to the saw arrangement having guide supports, an actual reduction of the friction between the saw blade and the guide supports is accomplished by the application within each guide support of a lubricating liquid to the saw body. A conventional saw arrangement including a representative illustration of this improvement is disclosed in McGehee U.S. In this saw arrangement a mixture of oil and water is applied to a saw body of a circular saw blade as it passes by guide supports retaining the saw blade in proper cutting alignment. Nevertheless, a need has arisen in recent years to reduce the thickness of a circular saw blade for cutting Southern Yellow Pine still further as demand for greater productivity in lumber mills has arisen. Such attempts at thinner saw blades generally have been unsuccessful due to insufficient cooling and consequent overheating, and better cooling techniques must be developed to advance this sought-after reduction in saw blade thickness.SUMMARY OF THE PRESENT INVENTIONThe present invention exhibits improved cooling of a saw blade retained in proper cutting alignment by lubricating saw guide supports, thereby advancing attempts to reduce saw blade thickness. The saw blade includes a saw body that defines a cavity therein and a cutting edge disposed along a periphery of the saw body for cutting during movement of the saw blade.
Each guide support includes the bearing surface being disposed immediately adjacent the saw body for support of the saw blade during cutting as well as a lubricating system comprising a recessed area extending from the bearing surface and containing liquid exposed to the saw body, whereby the liquid is applied to the saw body as it passes by the recessed area during movement of the saw blade.In a feature of the present invention, the cavity is arranged on the saw body to pass by the recessed area during movement of the saw blade and is dimensioned to receive liquid therein for transport away from the recessed area to be distributed to the saw body as well as a cutting area of the saw blade.
Preferably, the saw blade is circular, and the saw body is planar and includes three cavities disposed relative to one another at 120 degrees about the center of the saw blade. Each cavity is triangular in cross-section and extends from a first planar side of the saw body to a second planar side thereof. Also, each cavity preferably includes only rounded corners, and each cavity preferably has a radial dimension that varies along a circumferential direction of the circular saw blade between opposed circumferential ends of the cavity.The present invention also relates to a method of using a circular saw blade itself with a lubricating guide support assembly to cut lumber from Southern Yellow Pine. In particular, the circular saw blade includes a planar saw body having an axial thickness of no greater than 0.080 inches and defines a cavity therein having a radial dimension that varies along a circumferential direction of the circular saw blade between opposed circumferential ends of the cavity. In particular, the method includes the steps of delivering liquid into a recessed area of the lubricating guide support, filling a cavity of the saw body with the liquid by passing the cavity immediately adjacent the recessed area, and transporting the liquid away from the recessed area by continuing to move the cavity from the recessed area towards the cutting area.

3 including a cavity of the present invention.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTReferring now to the drawings, the present invention relates broadly to a saw arrangement 8 including the combination of a circular saw blade 10 and a lubricating guide support assembly 12. 1, this combination can be repeated to form what is commonly known as a horizontal gang saw 14 in the lumber industry. 3, the saw blade 10 includes a cutting edge 16 comprised of carbide insert teeth 18 for cutting during rotation of the saw blade 10. The saw blade 10 also includes a central opening 20 by which the saw blade 10 is mounted to an arbor 22 extending along an axis 24 that simultaneously drives each saw blade 10 by rotation in a circumferential direction ?. Furthermore, each planar saw body 28 preferably defines three liquid transport cavities 30 therein which extend entirely through the axial extent of the saw body 28 from a first planar surface 32 thereof to a second planar surface 34 thereof. Each cavity 30 is also triangular in cross-section in the embodiment shown, but other shapes are equally applicable.Regardless of the actual cross-sectional shape of the cavity 30 that is used, the cavity 30 preferably includes a radial dimension ? that varies along a circumferential direction ? of the circular saw blade 10 between opposed circumferential ends 36, 38 of the cavity 30 as shown in FIG. A trailing edge 42 of the cavity 30 is also preferably oriented at a negative angle ? of preferably 5 degrees with respect to a radius R of the saw blade 10.


These design configurations for the cavity 30 of the present invention prevent sawdust packing and enhance liquid distribution to the saw body 28 and cutting area 26 as discussed in detail below.The lubricating guide support assembly 12 includes a plurality of guide supports 44. 2, each guide support 44 includes a bearing surface 46 disposed immediately beside an adjacent saw blade 10 for proper alignment and support of the saw blade 10 during cutting. Each guide support 44 also includes a separate bearing surface 46 for each adjacent saw blade 10. The recessed area 48 is filled with a liquid under a pressure of approximately 35 psi that is exposed to the adjacent saw bodies 28, whereby a thin film of liquid is applied to each saw body 28 as it passes by the recessed area 48 during rotation of the saw blade 10. 4 corresponding to an area of the saw body 28 exposed to the liquid in the recessed area 48, the recessed area 48 preferably covers in one rotation of the saw blade 10 a large portion of an annular section of the saw body defined by dashed lines 50 thus providing for wide coverage of the saw body 28. 3, the cutting triangle 54 is an approximate right triangle having an arc 56 of the cutting edge 16 as a hypotenuse. In particular, the arc 56 extends between a first vertex 58 defined by the point where a carbide insert tooth enters the cant, and a second vertex 60 defined by the point where another carbide insert tooth simultaneously exits the cant. A first leg 62 lies along a bedplate 64 of the saw arrangement 8 and includes the first vertex 58, and a second leg 66 lies perpendicular to the bedplate and includes the second vertex 60. The rotation of the saw body 28 past the recessed area 48 and the disposition of the bearing surface 46 of each guide support 44 immediately adjacent the saw body 28 in conjunction with the pressurized liquid in the recessed area 48 results in a thin film of liquid initially being applied to the annular section defined by the dashed lines 50 shown in FIG. 4.Each cavity 30 is formed in each saw body 28 in this annular section defined by dashed lines 50 whereby each cavity 30 will pas by the recessed area 48 during rotation of the saw blade 10 as illustrated in FIG. As the cavity 30 passes by the recessed area 48 the pressurized liquid is driven into the cavity 30 and transported away from the recessed area 48 toward the cutting area 26.
Once the cavity 30 clears the bearings surface 46 of the guide support 44, air turbulence and inertial forces cause the transported liquid to pass out of the cavity 30 for distribution to the saw body 28 and the cutting area 26 including the cutting edge 16 of the saw blade 10 both before and within the cant. The distribution of liquid to the saw body 28 and to the cutting area 26 is thereby increased as opposed to simply applying a liquid film to the annular section define by dashed lines 50.The design configurations of each cavity 30 set forth above enhance this liquid distribution and prevent sawdust packing. In particular, due to the radial variance of ? in the dimension of the cavity 30, the cavity 30 is narrower at the leading point first 68 passing by the recessed area 48 and grows radially larger circumferentially along the saw body 28. This narrow-to-wide transition, in conjunction with the rounded corners 40 and negative angle ? of the trailing edge 42 of the cavity 30, draws the liquid into the cavity 30 and, when the cavity 30 clears the bearing surface 46, draws air into the cavity 30 displacing the liquid carried therein out of the cavity 30 in what is believed to be a vortex or swirling action. It has also been observed that the trailing edge 42, because of its angled orientation to the radius R of the blade 10, enhances distribution of the liquid toward the center of the saw body 28 before inertial forces draw the liquid in a direction from the center of the saw body 28 towards the cutting edge 16.
Moreover, during its pass through the cant, sawdust is driven towards the angled trailing edge 42 and is deflected thereby without finding niches to accumulate within, especially since the corners 40 of the cavity 30 are rounded. Thus, among other benefits of the present invention, sawdust packing is avoided without unduly limiting the radial dimension ? of the cavity 30 to a constant value less than 0.015 inches as taught by Carter Jr.
In particular, following cutting of lumber from Southern Yellow Pine, a layer of liquid along the cut lumber and relatively cool sawdust both were observed using the saw arrangement 8 of the present invention, but no liquid layer and relatively hot sawdust both were observed using the saw blade of Carter Jr. In particular, the rounded corners 40 and size of each cavity 30 allow for easier clean out and reshaping of the cavity 30 by a saw filer. For instance, the heating and cooling of the saw blade 10 causes the area of the saw body 28 defining the cavities 30 to harden, becoming brittle and cracking over time. By further rounding the cavities 30, the saw filer is able to file away these hardened areas without significantly altering the shape of the cavity 30. The filer can also refurbish openings defining the cavities 30 where the edges have been worn by friction, maintaining the integrity of the saw body 28 and the effectiveness of the liquid transporting capabilities of the cavities 30.Another benefit of the present invention over conventional saw arrangements including liquid lubrication guide supports such as that disclosed in McGehee is the reduction in the accumulation time of the liquid within the recessed area 48 due to the additional removal of the liquid from the recessed area 48 by the cavities 30.
Reduction of the time of the liquid within the recessed area 48 reduces the time in which the liquid within the recessed area 48 is thermally exposed to the guide support 44 and subjected to heat transfer via convection resulting from the abutment between each bearing surface 46 with an adjacent saw body 28.In sum, the liquid transport cavities of the present invention achieve a degree of cooling not obtained by the aforementioned conventional saw arrangements and provide greater operating life and easier and less maintenance than that of other conventional saw blades. Many embodiments and adaptations of the present invention other than those herein described, as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing description thereof, without departing from the substance or scope of the present invention. Accordingly, while the present invention has been described herein in detail in relation to its preferred embodiment, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for purposes of providing a full and enabling disclosure of the invention.
The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.Thus, it will be apparent, for example, that the liquid passageways of the guide supports could deliver the liquid under pressure directly to the saw body in the manner of liquid ports forming the recessed area of the guide supports, with the liquid transport cavities passing by the liquid ports for receipt of liquid directly therein. The cavities also do not have to extend entirely through the saw body, although better distribution of the liquid carried therein to the saw body and the cutting area is achieved when air turbulence passes through the saw body.
Moreover, the configuration of the cavity need not be triangular in cross-section nor have only rounded corners therein. It is only a requirement that the cavities be of sufficient area and dimension to receive a quantity of liquid therein from the guide supports as it passes thereby for delivery to the saw body and cutting area. It should also be apparent that while a horizontal gang saw has been used to illustrate the preferred embodiment of the present invention, the present invention is equally applicable to vertical gang saws or to single blade rip saws, whether vertically or horizontally disposed.
