DETAILED DESCRIPTION OF THE INVENTION

(12) The present inventor has devised a unique and innovative apparatus that enables a user to clean a saw blade quickly and efficiently. The apparatus is self-contained and may include additional implements and associated compartments that can aid in the cleaning process. The apparatus may also enable a user to clean tools other than a saw blade, such as router bits, shaper cutters, and the like.

(13) FIG. 1 is a perspective view of an example embodiment of a blade cleaning apparatus 100 disclosed herein. It includes a base 102 configured to retain a cleaning liquid therein, a lid 104 configured to be secured to the base 102 via latches 106, and a variety of tools and respective recesses in the lid 104 to store the tools. In this example embodiment, a brush 110 is disposed in a brush recess 112. Abrasive pads 114 suitable for a rotary tool such as a Dremel® are disposed in an abrasive pad recess 116. Abrasive pads 114 mounted on a tool bit 120 suitable for the rotary tool are disposed in a tool bit recess 122. A handle 124 having one or more magnets 126 is disposed in a handle recess 128. In alternate example embodiments, instead of magnets 126, the handle 124 may include suction cups or other temporary surface mounting hardware. An example handle is a GRRR-RIPPER handle made by MicroJig of Winter Park, Fla., with suitable magnets attached to the ends. Each recess has a respective grip-relief 132, 134, 136, 138 that enables a user to grip the respective tool when removing or replacing the tool from the recess. One or more of the recesses may be at least partly form fitting and/or may be configured to hold the respective tool therein via a press fit or a compressive fit or a snap-in fit between the tool and the walls that form the recess.

(14) In an example embodiment, the blade cleaning apparatus 100 also includes a router bit cleaning feature that includes a router bit cleaning compartment lid 150 to which a router bit holder (not visible in FIG. 1) is secured and that covers a router bit cleaning compartment(not visible in FIG. 1).

(15) FIG. 2 is a perspective view of the blade cleaning apparatus 100 with the lid 104 removed to expose an abrasive mat 200 configured to rest on a bottom 202 of the base 102 and to support a saw blade such as those used in table saws, miter saws, and circular saws in a horizontal orientation. In an example embodiment, the abrasive pad is or is comparable to a Scotch-Brite™ pad made by 3M. An example diameter is thirteen (13) inches in order to be able to clean a wide range of saw blade sizes. The base 102 includes a centering post 204 configured to protrude up through a center of the saw blade. In addition, in this example embodiment, a watertight seal is formed between the base 102 and the lid 104 via an O-ring 210 or another suitable element known to the artisan. In this example embodiment, the latches 106 are the type that secure the lid 104 to the base 102 by pulling the lid 104 down onto the base. This compresses the O-ring 210 to form the watertight seal configured to retain a liquid in the base 102.

(16) FIG. 3 is a side cross sectional view of the blade cleaning apparatus 100 of FIG. 1. In an example embodiment, at least one of the base 102 and the abrasive mat 200 comprises a taper such that a perimeter of the saw blade resting thereon is supported whereas a center of the saw blade is not supported. In this example embodiment, the bottom 202 of the base 102 is angled at an angle 300 so that a distance 302 at a radially inner edge 304 of the abrasive mat 200 is larger than a distance 306 at a radially outer edge 308 of the abrasive mat 200. The abrasive mat 200 is shown as flat and horizontal. The saw blade 310 rests in a horizontal orientation atop the abrasive mat 200 and the centering post 204 protrudes up through a center 322 of the saw blade 310. Due to the angle 300 and the flexible nature of the abrasive mat 200, teeth 324 (e.g. carbide teeth) disposed at the perimeter 326 of the saw blade 310 are supported by the abrasive mat 200 while the center is not likewise supported. A cleaning solution liquid is disposed in the bottom 102 and the saw blade 310 is submerged below a surface 330 of the liquid. Example liquids include Simple Green made by Sunshine Makers Inc., Pine Sol® made by Clorox®, laundry detergent, baking soda with water, and even plain water.

(17) As can be seen in FIG. 3A, the handle 124 can be used to handle the saw blade 310. In an example embodiment, the magnets 126 generate about ten pounds of pull force on the saw blade 310. By placing the handle 124 on the side of the saw blade 310, the saw blade 310 can be safely placed in the liquid to reach the configuration shown in FIG. 3 and FIG. 3A without the user having to touch either the saw blade or the cleaning liquid. The saw blade 310 may be left to soak for as little as under a minute, for example, twenty (20) seconds. The user can then press down gently. This causes the center of the saw blade 310 to flex down, at which time the user can merely spin/rotate the saw blade 310 about the centering post 204 for as little as a quarter to half a turn to remove the pitch and gum. Because the perimeter 326 of the saw blade 310 is supported and the center 322 is not, pressing down gently on the saw blade 310 increases a contact force between the teeth 324 and the abrasive mat 200. The spin action translates the teeth across the abrasive mat 200 which abrades the pitch and gum off all of the teeth 324 simultaneously in about ten (10) to fifteen (15) seconds. The saw blade 310 can be flipped and the process can be repeated to clean the other side of the teeth 324. Accordingly, a user can clean a saw blade 310 in this manner much quicker and easier compared to prior art techniques.

(18) FIG. 4 is a perspective view from below of a cross section of the blade cleaning apparatus 100 showing the router bit cleaning compartment lid 150, a router bit holder 400 secured to an underside 402 of the router bit cleaning compartment lid 150, and a router bit recess 404 in an exterior surface of the lid 104. In example embodiments, the router bit holder 400 may be composed of a resilient material (e.g. rubber, foam etc.). A base of a router bit can be inserted into a bit receptacle 410 so that the router bit holder 400 is held upside down in the router bit recess 404. A cleaning solution liquid may be disposed in the router bit recess 404 so that a tip of the router bit is disposed below a surface 412 of the liquid. The router bit may be left to soak until it is removed and may additionally be manually cleaned using, for example, any of the tools secured in the lid 104 and/or the rotary tool.

(19) FIG. 5 is a perspective view of another example embodiment of the blade cleaning apparatus 500 disclosed herein. It likewise includes a base 502 configured to retain a liquid therein, a lid 504 configured to be secured to the base 502 via latches 506, and a variety of tools and respective recesses in the lid 504 to store the tools. In this example embodiment, a brush 510 is disposed in a brush recess 512, and a handle 524 having one or more magnets 526 is disposed in a handle recess 528. In alternate example embodiments, instead of magnets 526, the handle 524 may include suction cups or other temporary surface mounting hardware. Each recess has a respective grip-relief 532, 534, that enables a user to grip the respective tool when removing or replacing the tool from the recess. One or more of the recesses may be at least partly form fitting and/or may be configured to hold the respective tool therein via a press for or a compressive fit or a snap-in fit between the tool and the walls that form the recess. In this example embodiment, the blade cleaning apparatus 500 also includes a router bit cleaning feature that includes a router bit cleaning compartment lid 550 to which a router bit holder (not visible in FIG. 5) is secured and that covers a router bit cleaning compartment(not visible in FIG. 5). Also visible is an upper grip recess 560 that cooperates with a lower grip recess (see FIG. 9) to enable a user to easily grab and carry the blade cleaning apparatus 500.

(20) FIG. 6 is a perspective view of the blade cleaning apparatus 500 of FIG. 5 with the lid 504 removed to expose an abrasive mat 600 configured to rest on a bottom 602 of the base 502 and to support the saw blade. In this example embodiment, the base 502 includes a centering post 604 configured to protrude up through a center of the saw blade. In addition, in this example embodiment, a watertight seal is formed between the base 502 and the lid 504 via an O-ring or another suitable element known to the artisan. The latches 606 in this example embodiment are the type that secure the lid 504 to the base 502 by pulling the lid 504 down onto the base. This compresses the O-ring to form the watertight seal configured to retain a liquid in the base 502.

(21) Also visible is a saw blade holding station 610 including a blade slot 612 configured to hold the saw blade in a vertical orientation. The blade slot 612 shown has a rounded shape to conform to the perimeter of the saw blade. The saw blade may be placed in the blade slot 612 to dry after cleaning. The blade slot 612 may also be used to safely hold the saw blade while the user moves the handle 524 from one side of the saw blade to the other without the user's hand touching the saw blade and/or cleaning chemicals. Any liquid pulled by gravity into the blade slot 612 may drain from the blade slot 612 into the base 502 via a drain 614. A recess 616 adjacent the blade slot 612 can receive the handle 524 when the saw blade is lowered into the blade slot 612. Having the handle 524 disposed toward the bottom of the upright saw blade in the blade slot 612 enables a user to pull/pry the handle 524 from the saw blade while the blade slot 612 holds the saw blade in place. The embodiment of FIG. 6 may include some or all of the same features of the embodiment of FIG. 1 in addition to the saw blade holding station 610. Likewise, the embodiment of FIG. 1 may include the saw blade holding station 610 of FIG. 6.

(22) FIG. 7 is a side cross sectional view of the saw blade holding station 610 of the blade cleaning apparatus 500 of FIG. 5. In this example embodiment, any fluid from the blade slot 612 will enter the drain 614 via gravity and will then drain into the bottom 502 because a bottom 700 of the drain 614 is sloped at an angle 702 into the bottom 502. It can also be seen that, like the embodiment of FIG. 1, the bottom 720 of the base 502 is angled at an angle 722 so that a distance 724 at a radially inner edge 726 of the abrasive mat 600 is larger than a distance 728 at a radially outer edge 730 of the abrasive mat 600.

(23) FIG. 8 is another side cross sectional view of the saw blade holding station 610 the blade cleaning apparatus 500 showing the arcuate shape of the blade slot 612. In example embodiments, the arcuate shape can match that of the saw blade, such as but not limited to 4.5 to 7.25 inches for handheld circular saw blades, and seven (7) or ten (10) inch saw blades for table and miter saws.

(24) FIG. 9 is a perspective view showing the lower grip recess 900 of the blade cleaning apparatus 500 of FIG. 5. The lower grip recess 900 cooperates with the upper grip recess 560 to enable a user to carry the blade cleaning apparatus 500. For example, a user may put a thumb in the lower grip recess 900 and one or more fingers in the upper grip recess 560 and thereby be able to hold and carry the blade cleaning apparatus 500.

(25) While various embodiments of the present invention have been shown and described herein, it will be obvious that such embodiments are provided by way of example only. Numerous variations, swapping of features among embodiments, changes, and substitutions may be made without departing from the invention herein. Accordingly, it is intended that the invention be limited only by the spirit and scope of the appended claims.
